MINI REPORT #1 MATV

8936 Mechanical Project – MATV Pg 1

1 Scope

The scope of project MATV – Memorial All Terrain Vehicle is to design a hydraulically powered

amphibious vehicle, able to navigate through rough terrain, typical of a Newfoundland off road

environment. The vehicle will have automated controls, however the design of these are outside

the scope of the current term deliverables.

Project MATV strives to improve upon the design of existing competitors vehicles that have inherent

design weaknesses. Typical competitors have limited off road abilities, low operational speeds, and

limited pay loads. Another common downfall seems to be the low power to weight ratio and short

autonomy, associated with their choice of battery powered vehicles.

Future scope for this project may include autonomous navigation through rough terrain, GPS

surveying, integration with other potential projects such as active suspension systems, aerial

machine vision projects, etc.

2 Project Team

Our project team is made up of three senior mechanical students, all completing term 8 of the

mechanical engineering program at Memorial University of Newfoundland. This project will serve

both as a senior mechanical design project for the team, as well as an ongoing initiative for the

engineering faculty.

The “ongoing initiative” of the faculty refers to the future scope outlined above, which may become

a planned progression for the project, most likely completed as part of future design projects for

future engineering students.

MINI REPORT #1 MATV


The current team management chart is pictured below:

Figure 1: MATV Project Management Chart

As evident in the management chart, a large portion of the project will be the technical design of

various systems and components that make up the MATV. Due to small group numbers, the team

lead (team member that manages communications between team and supervisor) has also taken

the position of technical lead. We have broken the technical aspects of the project into 4 sections,

hydraulic design, suspension design, wheel/hub design, and platform design.

Hydraulic design can be thought of as the design of the system from gasoline powered engine to

closed pump/motor hydraulic system, and all components supporting these main parts. Suspension

design can be thought of as the double a‐arm suspension, the spring/shock combo connected to the

arms, and the mounting arrangement between the suspension and the main platform or chassis.

Wheel and hub design is best described as the design of the wheel uprights, the design of the hub

connecting to the hydraulic wheel motors, and an integration of the upright into the suspension

design.

MINI REPORT #1 MATV


As shown in the aforementioned chart, the design of the platform or chassis will be done as a team,

after the various components have been completed. We reasoned that an integration of the

suspension design and the hydraulic systems design will be significant in platform design, so a team

effort we will bring the platform design to completion, to incorporate these components and fulfill

the platform specifications as described in the following section.

3 Specifications

3.1 General

The vehicle will incorporate an independent 6 wheel power train and suspension, which will be

hydraulically driven. The suspension design will be a double a‐arm with upper shock mount (shock

mounted on the upper a‐arm) instead of the standard lower shock mount. Each wheel will have its

own hydraulic wheel motor, with the left side and right side of the vehicle controlled with

independent hydraulic circuits.

The vehicle will be amphibious, meaning that not only will it be able to navigate water obstacles, but

it will do so without damage to its onboard operational systems.

3.2 Platform

The current goal for the total weight of MATV is 300lbs, with additional allowance for a 50 lb

payload. The platform should provide at least 2 cubic feet of cargo space, and allow for the

attachment of components for navigation, automation, and equipment for various future activities.

The entire MATV (including platform) will be designed with 12‐14” of ground clearance, and be less

than 48” wide, with a wheel diameter of 0.3m.

MINI REPORT #1 MATV


3.3 Performance

The MATV vehicle will be designed for a 24 hour automation period. This means that the vehicle

must be able to carry enough fuel and run long enough to survive at least a 24 hour period without

any outside interactions. Currently the only design modification to support this spec will be a larger

fuel tank, able to carry enough fuel for a 24 hour period.

The vehicle is designed to attain a speed of 30 km/hr on a flat, horizontal surface. When designing

our hydraulic system, this specification was a crucial factor in the sizing of the pump (pump

flow/displacement), and ultimately in the power required of the engine.

The MATV is designed with enough torque to climb a vertical wall if encountered, meaning that the

front 2 wheels have enough torque to lift ½ the weight up the vertical obstacle while the rear

wheels propel the vehicle into the wall. Theoretically the vehicle could climb a vertical wall with all

6 wheels; however this is obviously not a consideration in realistic design.

4 System Design

4.1 Hydraulic Design

Project MATV makes use of a robust hydraulic drive train system powered by a 4 stroke, air cooled,

single piston gasoline engine. The gasoline engine drives a tandem hydraulic pump, which supports

two closed hydraulic loops (one left side, one right side), driving 3 hydraulic wheel motors per

loop/side.

The hydraulic system operates at 2000psi. Original design was carried out with a standard 3000psi

baseline, however due to the availability of essential components such as the hydraulic wheel

motors, a more “component friendly” 2000psi operating pressure was chosen.

MINI REPORT #1 MATV


Pictured below (on the next page) is a schematic of the hydraulic system that will be implemented in

the MATV. Reading from “left to right”, you will first see the gasoline engine driving the reversible

pump. This reversible pump in this circuit represents half of the tandem pump that we will be using,

and also represents a bi‐directional hydraulic transmission for the vehicle. While the hydraulic

wheel motors are of a fixed displacement, and the engine is governed at 3600rpm with a fixed

power and torque setting, the variable pump is essentially what controls the system during

operation by adjusting the “slip” or displacement of the pump.

The reversible pump drives all 3 wheel motors in the circuit, which have an equal pressure drop

since they are in series. Using the stated 2000psi pressure drop, a pressure drop of approximately

667psi per wheel motor will be seen.

Each wheel motor as well as the pump share a lubrication drain circuit, which allows the fluid used

in component lubrication to circulate back to the tank through an air to liquid radiator. A relief valve

is fitted to the system to prevent undesirable overpressure of the system. In the event of an

overpressure (operating pressure that exceeds the relief valve pressure), the relief valve will open to

allow high pressure fluid to bypass the hydraulic wheel motors, and take the path of least resistance

back to the low pressure side of the circuit.

Finally, you will see a filter located just after the tank; all additional fluid required by the system

travels through the filter and into the low pressure side of the system to make up for the loss due to

the pump and motor drainage circuit.

MINI REPORT #1 MATV


Figure 2: Hydraulic System Model

4.1.1 Gasoline Engine

The gasoline engine chosen for this project is a Honda GX200, it is a reliable 4‐stoke, air cooled,

overhead valve, single piston engine. This engine is rated at 5.5Hp (4.1kW) at 3600rpm, with a

net torque of 9.1 lbs∙ft (12.4 Nm) at 2,500 rpm. The engine is governed at a speed of 3600rpm,

achieved through a centrifugal mechanical governor system. This engine satisfies our calculated

design specification of 5.11 Hp at a 2000psi operating pressure. The torque and power curves

are shown below (next page).

MINI REPORT #1 MATV


Figure 3: Honda GX200 Specifications

The displacement of the GX200 is 196 cm3 (12.0 cu in) with a bore of 68mm (2.7 in) and stroke

of 54 mm (2.1 in). The compression ratio of the single piston is 8.5:1 with a counter clockwise

Power Take Off (PTO) shaft rotation. The engine is carbureted with a horizontal type butterfly

valve and dual element type air cleaner, as opposed to the conventional paper type air filter.

The engine has a forced splash lubrication system with oil capacity of 0.6L (0.63 US qt), and fuel

tank capacity of 3.1 L (3.3 US Qt.). The fuel tank, as mentioned will be removed and replaced

with a modified fuel tank, able to handle the 24 hour automation requirements.

The dimensions of the engine are (L x W x H) 321mm (12.6 in) x 376mm (14.8 in) x 335mm (13.2

in), with a dry weight of 16.0 kg (35.3 lbs). The engine has a transistorized magneto ignition

system, as well as an electric starter system with backup recoil system.

MINI REPORT #1 MATV


Figure 4: Honda GX200 Engine

We are currently awaiting an official quote from Powerquip‐div.of Barrett Marketing Group in

Dartmouth, NS. Powerquip are an official supplier of Honda small engines for Atlantic Canada,

and have the GX200 listed at $807 CAD. Our official quote should come in at a much lower price

than the list price, as this engine is for use in an official university project; the official price quote

will be reflected in our next report. It is worth noting that we are also expecting a quote from

the local “Honda One” dealership, however we anticipate this quote to come in higher than the

quote from the official supplier, as they would be acting as a secondary distributor.

4.1.2 Tandem Variable Hydraulic Pump

The variable hydraulic pump chosen for our system is a Sauer‐Danfoss “15 Series” 15PT Tandem

Pump. The pump has a maximum displacement of 0.913 in3/rev (15 cc/rpm) ‐ this is 0.913

in3/rev per outlet, which means a maximum of 2 x 0.913 in3/rev overall for the variable tandem

pump; satisfying our calculated design displacement of 0.84 in3/rev.

The pump has a continuous operating pressure of 2500 psi, easily satisfying our 2000psi

requirements, and a maximum operating pressure of 4500psi. The pump has a charge pump

built in, eliminating the need for a pressurized tank, and supplying 0.33 in3/rev (5.4 cc/rev) of

charge flow.

MINI REPORT #1 MATV


Using the supplied PV charts (similar model pump), we have estimated the pump flow rate to be

approximately 51 L/min (13.5 gpm). This satisfies our design calculation of 44.83 L/min for

pump flow rate.

The pump has overall dimensions of (L x W x H) 394mm (15.5 in) x 215mm (8.5 in) x 178mm (7.0

in) and an overall dry weight of 64 lbs (29 kg). At the time of this report, we have not acquired

an official quote for this tandem pump. We have contacted and requested a quote from the

local company Hydraulic Systems limited, who are an official supplier, and anticipate a quote

shortly.

4.1.3 Hydraulic Wheel Motors

The hydraulic wheel motors chosen for the project are Parker TJ 0080 motors with built in wheel

bearings. These motors are “medium frame” Gerotor motors, and were chosen due to their

output shaft design, light weight, and close specifications to our design model.

Figure 5: Parker TJ 0080 Wheel Motor

MINI REPORT #1 MATV


The fixed displacement of the motor is 5 in3/rev (82 cm3/rev), which satisfies our requirement of

4.6 in3/rev (76 cm3/rev), and the continuous flow rate is 45 L/min (12 gpm), satisfying our

requirement of 44.8 L/min (~12 gpm). The maximum flow rate is 57 L/min (15 gpm).

The max speed of the motor is 695 rpm, satisfying our 530 rpm requirement, and the continuous

torque of 160 N∙m (1416 lb∙in) easily satisfies our 50.2 N∙m requirement. The maximum

intermittent torque of the motor is 220 N∙m (1947 lb∙in).

The overall dimensions of the motor (L x W x H) are 222mm (8.73 in) x 135mm (5.31 in) x 135mm

(5.31 in), and the overall dry weight is 15.6 lbs (7.1 kg). We did obtain one local quote from

Beattie Industrial Ltd. for $720.00 CAD ea, however we are still awaiting quotes from the local

company Hydraulic Systems limited, who are an official supplier for Parker.

4.2 Suspension Design

For our suspension design we have decided to use a double wishbone suspension; also referred to

as a double A‐arm suspension. A double wishbone (or upper and lower A‐arm) suspension is an

independent (left to right) acting suspension design using two wishbone or A‐shaped arms to locate

the wheel. Each wishbone or arm has two mounting points to the chassis and one joint mounted to

the knuckle (or upright). The shock absorber and coil spring mount between the chassis and one of

the wishbones to control vertical movement of the suspension arms.

This design allows us to carefully control the motion of the wheel through the suspension travel,

controlling such parameters as camber, caster, toe, roll center height, scrub radius, scuff and more.

Due to the design of the platform/body the upper arm will be shorter than the lower arm. This will

induce negative camber as the suspension travels through its path.

MINI REPORT #1 MATV


When the vehicle is in a turn, body roll results in positive camber gain on the inside wheel, and

negative camber gain in the outside wheel due to the shorter upper arm. Although not overly

critical in our relatively low speed application, our suspension design will attempt to balance these

two effects and keep the tire perpendicular to the ground.

Another advantage to the double wishbone suspension is that it is fairly easy to work out the effect

of moving each joint, so we should be able to easily model our suspension travel to optimize wheel

motion. We are also able to work out the loads that each part is subjected to, allowing us to safely

design our suspension components. The picture below shows a typical design of a double A‐arm

suspension system with an upper arm shock mount. This design allows maximum room for fitment

of the hydraulic wheel motor at the upright, and between the control arms, even during suspension

travel.

Figure 6: Double A‐Arm Suspension with Upper Shock Mount

A design that we had not previously considered, but which came up later during research is the

extended upright as pictured below. This design still allows for use of a double a‐arm suspension,

and also allows for additional ground clearance and additional room for the hydraulic wheel motors.

MINI REPORT #1 MATV


Figure 7: Alternate A‐Arm Suspension Design

Having both A‐arms parallel and attached to the upright as shown will provide greater ground

clearance than traditional a‐arms which are angled toward the chassis to provide sufficient ground

clearance. Here, our shock absorber can attach to the base of the lower a‐arm, and at a higher point

on the chassis to allow for maximum strut travel, and hence maximum suspension travel.

4.3 Wheel/hub Design

Hub design is based on the stresses generated by operational loads acting on the wheels. During the

design of the wheel hub and upright, estimated load conditions must be taken into account as well as

the stresses and fatigue of the assembly.

The wheel assembly will include a low speed high torque motor which will drive each individual wheel in

order for the vehicle to navigate obstacles and rough terrain. Our team will be designing and fabricating

both an upright and a wheel hub which will mount directly onto the motor.

The uprights will attach the wheel motor to the suspension arms, while the hub attaches the wheels to

the wheel motors, and to the both through the uprights and suspension arms. The main goal of our

design is to make the component as light as possible while not altering the performance of the

mechanism.

MINI REPORT #1 MATV


Wheel sizing was outlined in the original system design calculations, and the task now is to find suitable

wheels and tires that will provide the correct overall diameters, sufficient grip, and be reasonably light

weight. Several companies have been considered for the supply of wheels and tires, some of these

include Coastal Marine & Recreation, Eastern Hydraulics, Princess Auto and Canadian Tire. These

companies are all local, and if suitable wheels and tires are found, the convenience and swift availability

would make these attractive suppliers for the project. Approximate dimensions of the tires are 12”

overall diameter (0.3m), 4‐5 inches wide, and a suitable tread design for an off‐road environment.

Both the hub and uprights will be designed by the team, and fabricated locally (if not by the team). The

hub will be attached to the motor by means of a taper press, key, and castle nut if applicable. The built

in bearings in the motor shaft provide a simple solution for attaching the wheels to the vehicle without

the need for bearings in the upright, or a typical splined hub and CV joint/axle.

The uprights will be mounted on the cylindrical section adjacent the motor shaft, and bolted to the

motor using 4 threaded holes located on the motor.

Figure 8: Wheel Motor Schematic

MINI REPORT #1 MATV


4.4 Platform

The design of the MATV platform/chassis is based upon an Argo type rover. This platform is able to

support rough terrain and water environments, and is strong enough to sustain damages from rough

operation. Our MATV platform will consist of a hull shaped structure, being amphibious and maintaining

a large top section to support equipment, expansion, and other various tasks. The platform requires

approximately 2 cubic feet of cargo space in addition to the room needed for components such as the

engine, pumps, electronics, hydraulics, etc. The entire platform should consist of the dimensions of 4

feet long and 3 feet wide for the purpose of not easily capsizing.

The platform must be light weight to support the overall MATV weight of 300 lbs. In addition to the 300

lbs overall weight, a 50lb payload must be supported by the MATV. The material that most closely

meets these requirements is aluminum, due to its light weight and rugged properties. Shown below is a

picture of an Argo platform, similar to the MATV anticipated design.

Figure 9: Argo ‐ Platform Design Base

Thus far, the designing of the platform has not been explored in detail due to the attention paid to the

other main components. Following the design of the main components, the final design of the platform

will be explored and finalized.

MINI REPORT #1 MATV


5 Deliverables

Deliverables for this term will focus on the basic operation of the MATV vehicle. Automation of the

vehicle and detailed design of the onboard systems will not be focused on this term. One

deliverable for the term will be the design and fabrication of one complete hydraulically powered

wheel assembly. This includes the closed loop hydraulic system, the engine to power the system,

and all components related to hydraulic operation.

In addition to the hydraulic system, a large deliverable for the term will be the design and

fabrication of a wheel, hub and upright assembly, as well as the suspension design to support the

assembly. Integration of the hydraulic system into the suspension and wheel design will be a large

design milestone in the project.

A final deliverable, if possible, will be the design of an amphibious platform to support the hydraulic

power train, suspension setup, vehicle automation equipment, and payload. In addition to the

physical deliverables this term, there are a number of documentation oriented deliverables that tie

into the course evaluation.

A final report and presentation will be prepared for the end of the term, documenting all progress

and deliverables achieved during the term, as well as a complete design package to accompany the

physical deliverables. Several mini reports and presentations will also be completed during the term

to complement term progress and support the final documentation.

A team website will be maintained throughout the term, as a main hub for all completed work, and

as a management tool for all team progress. Finally, log books will be submitted at the end of the

term to help complete the documentation requirements for the term.

6 Competitors

6.1 FosterMiller

Currently Foster‐Miller is one of the world’s largest providers of Robotic systems, and although their

products are world renowned, we feel they can be improved. Foster‐Miller boast having the fastest

robot on the market today with a top speed of 8km/hr, and claim to have a very long battery life, which

due to battery design is actually limited to just hours. Foster‐Miller’s family of automated robots, “The

Talon”, is very limited to the terrain it can cover with a primary track design, limited to “even” ground,

and not dealing well with any obstacles.

The Talon’s line of attachments do provide flexibility, however the quality of attachment and design is

often questionable, and sometimes seem to be a “quick” or “under designed” solution. Often the

attachments seem to be “off the shelf” parts that have been attached to the vehicle without any real

thought to base vehicle integration. As you can see below the Talon does not have any payload

capabilities, and the two mounting poles really limit what attachments can be used.

Figure 10: Foster Miller Talon

MINI REPORT #1 MATV


The MATV platform will not only have 2 cubic feet of cargo space it will have an adjustable attachment

center allowing the attachment of a wide variety of items. Our designed top speed is approximately 4

times faster than that of the Talon family, and with our increased gas tank volume, our operation life is

designed for at least twenty‐four hours. With our amphibious design our platform is able to travel over

land and water and by using hydraulics we have a superior power to weight ratio. The only advantage

the “Talon” seems to have is the light weight design; however we feel that our advantages listed above

outweigh the weight savings.

6.2 Frontline Robotics

Frontline Robotics takes the approach of modifying existing vehicles with their control systems to make

them autonomous or remotely controlled. This approach allows them to offer a range of vehicles, but

limits their attachment abilities and presents size constraints. One of the more popular vehicles they

modify is the Argo; and although it offers an amphibious platform, it is limited by its suspension design

and overall size.

Figure 11: Frontline Robotics Modified Argo

MINI REPORT #1 MATV


A disadvantage of using an existing vehicle platform for automation is the existing power to weight

ratio’s and range limitations. Our vehicle is designed with plenty of torque/power, and long range

operation in mind. The application for the Frontline fleet is more of security surveillance, they are able

to patrol an area and relay information from the perimeter back to a central system; they are not

intended for long range expeditions. For this reason the Frontline Robotics Fleet is not considered a

direct competitor. The MATV will not only be able to patrol a small area if needed, but can extend its

range over long distances, maintaining a fully autonomous operation over harsh terrain.

7 Project Timeline

Currently the project is in progress and meeting the majority of the timeline requirements. As seen in

the image below, overall project design is progressing well, and we hope to align with all items on the

the original Gantt chart very soon.

Figure 12: MATV Project Timeline

MINI REPORT #1 MATV


8 Cost Analysis

Although we are still currently waiting on official quotes from some suppliers, we have received quotes

or estimated costs on most of the key components for our project. In the table below you can see which

items we currently have priced and the estimated cost.

Figure 13: MATV Cost Estimate

In regards to the hydraulic parts, we gathered an average price of the fittings and hose from McMaster‐

Carr with an estimate of the number of fittings and length of hose that are required. However we will

most likely acquire the hose and fittings from Princess Auto to ensure timely deliver and ease of

procurement. The scope of our work is to design and test one complete closed loop hydraulic wheel

assembly therefore the cost of the project will be substantially reduced compared to the

aforementioned table.

MINI REPORT #1 MATV


9 Weight Analysis

As outlined in the table, our previous design specification of 300lbs total came in much lower than

anticipated. Due to the large weight of fluids, and components located within the wheel hubs, our

estimate is much higher than the original design weight. This additional weight will have to be

accounted for with a slight design iteration.

Figure 14: MATV Weight Estimate

Furthermore, this excludes the fifty pound payload specified in the original design. We anticipate that

the large power to weight ratio provided by the hydraulics will compensate for the additional weight,

and provide more than enough torque to meet the other design specifications required at the beginning

of the term.

Description of Operation for Series 70 and 15 Series Products

Basic Pump/Motor CircuitA typical hydrostatic transmission consists of a vari-able displacement axial piston pump connected inclosed circuit to a fixed displacement axial pistonmotor. There are two basic arrangements of hydro-static transmissions:

1. A split system in which the pump and motor aremounted separately. Pressurized fluid is con-tained and directed through hoses or tubing.

2. An integral system in which the pump and motorare contained in the same housing with pressur-ized fluid internally contained.

The variable pump (PV) is driven by a prime mover,typically an internal combustion engine. The fixedmotor (MF) drives the vehicle transmission or otherwork function. Direction of rotation and speed of themotor shaft depends on the output flow of the pump.System pressure is dependent upon vehicle tractiveresistance or other work function requirements.

Variable Displacement PumpThe variable displacement pump (PV) is an axialpiston design. It has a mechanical control connectedto the swashplate. In operation, as the machineoperator moves the control handle, the swashplatetilts. This tilting results in fluid flow from the pump,with the amount of fluid flow being proportional to theswashplate tilt angle. The direction in which fluid ispumped depends on input rotation and the side ofneutral that the swashplate is tilted or stroked. Re-versing the swashplate angle reverses the flow offluid.

Fixed Displacement MotorThe fixed displacement motor (MF) is an axial pistonmotor that has the swashplate at a fixed angle, givingit a fixed displacement. The direction of motor shaftrotation depends on the direction of fluid flow throughthe motor. Changing the direction of fluid flow throughthe motor causes opposite motor shaft rotation.

Direct Displacement ControlThe variable displacement pump swashplate in boththe Series 70 and 15 Series transmissions is directlycontrolled. For the Series 70 pump, any movement ofthe control shaft results in a proportional movementof the swashplate, with 21 degrees of control rotationresulting in 15 degrees of swashplate rotation. Forthe 15 Series pump, any movement of the controlshaft results in equivalent swashplate movement,with 15 degrees of control shaft rotation resulting in15 degrees of swashplate rotation.

MF OUTPUT

Charge PumpAxial piston pumps and motors use a small amountof fluid for internal lubrication. This results in fluidbeing lost from the closed circuit that must be replen-ished. A fixed displacement gerotor pump is used toreplenish the lost oil. This gerotor pump, called acharge pump, is driven by the prime mover throughthe piston pump drive shaft.

Since the piston pump and piston motor are con-nected in a closed circuit, either side of the hydro-static loop may be pressurized. To allow charge oil toenter the closed circuit, two check valves are used todirect charge flow to the side of the loop with thelowest pressure.

The pressure in the charge pump circuit is limited bya direct operating relief valve. Any fluid not used asreplenishing oil is discharged over this valve, eitherinto the transmission case or recirculated back to thecharge pump inlet. Flow across a small fixed orificeconnecting the charge circuit with the transmissionhousing, supplements the cooling flow in the Series70 transmissions.

Inlet FilterIt is imperative that only clean fluid enters the hydro-static transmission circuit, therefore a 20 micron(nominal rating) inlet filter is required in the chargepump inlet line. This filter should not have a bypassand should be changed regularly to ensure systemreliability.

Bypass ValveIn some applications, it is desirable to move themachine for short distances at low speeds withoutstarting the engine. A bypass valve allows oil to berouted from one side of the pump/motor circuit to theother, thus allowing the motor to turn. The bypassvalve must be fully closed during normal vehicleoperation.

Series 70 BDU-10L and 21L transmissions utilize aspool type bypass valve. A spring closes this valve onthe 10L transmission, while charge pressure closesthe valve on the 21L transmission. The BDP-10Lpump utilizes a screw type bypass valve.

15 Series PV, PT, and in-line units utilize a screw typebypass valve which is fully open at 1/2 revolution ofthe valve stem. 15 Series U transmissions utilize thecharge check valves for the bypass function. Exter-nal plungers are depressed to hold the charge checkballs off of their seats, allowing oil to bypass from oneside of the pump/motor circuit to the other.

Implement Circuit – 15 Series

Implement PumpImplement (auxiliary) flow capability is offered on theSeries 70 21 cc transmission and on 15 Series units.Charge (implement) pump sizes available are .18 in3/Rev. (3 cc/rev.) for the Series 70 BDU-21L transmis-sion, .30 in3/Rev. (4.9 cc/rev.) for the 15 U transmis-sion and .33 in3/Rev. (5.4 cc/rev.) for the 15 PV, 15PT, or 15 in-line transmission.

The implement circuit must be of the “open center”type that allows oil from the charge pump circulatingthrough the control valve to return to the transmis-sion.

There are two styles of implement circuits dependingupon whether the Series 70 or the 15 Series is used.

In the Series 70 BDU-21 implement circuit, flow fromthe charge (implement) pump flows first to the imple-ment circuit control valve, then to the charge reliefand charge check valves. The implement circuitmust be designed to return the implement flow to thetransmission. (A check valve is provided to allow oilto be drawn into the charge circuit should the flowreturning from the implement circuit be momentarilyinsufficient to charge the closed loop.) The customermust provide an implement circuit relief valve inaddition to the implement control valve. It is alsorecommended that the customer provide a chargepressure filter between the implement control valveand the transmission to prevent any contaminantscreated in the implement circuit actuator(s) fromentering the charge circuit.

In the 15 Series implement circuit, flow from thecharge (implement) pump flows to the charge checkvalves and charge relief. Once charge pressure isestablished, the charge relief allows oil to flow to theimplement control valve, and on to the transmissioncase drain. (If an oil cooler is required in the circuit, itmay be installed between the implement controlvalve and the case connection.) The implement reliefvalve limits the pressure in the implement circuit (andcharge circuit) when the implement valve is actuated.

1 3


Easy-Ride ValvesThe Series 70 BDU-21L transmissions are availablewith optional Easy-Ride valves to reduce the rate ofchange in acceleration (“jerkiness”) in vehicle propelapplications. Each Easy-Ride valve incorporates apoppet-piston, sleeve assembly, valve spring, andplug.

A sudden increase in pressure in one side of theclosed loop will open the corresponding Easy-Ridevalve, allowing some high pressure fluid to flow to theopposite side of the loop through the charge circuitand charge check. This limits the pressure rise ratein the loop and reduces the acceleration rate of thevehicle.

The poppet-piston, sleeve assembly, and spring actas an accumulator. Once system pressure builds-upbetween the poppet-piston and sleeve assembly, thepoppet-piston will move toward its seat, closing thepassage.

A typical Easy-Ride valve cycle requires 0.5 to 1.0seconds, depending on system oil viscosity and looppressure. If the loop pressure is above the functionalrange of the valve (approximately 1500 psi [103 bar]),the valve spring will compress until the sleeve as-sembly contacts the plug, and the poppet-piston willbe rapidly forced onto its seat.

Speed RatingsMaximum speed is the highest operating speedrecommended and cannot be exceeded without re-duction in the life of the product or risking prematurefailure and loss of drive line power (which may createa safety hazard).

Continuous speed is the speed limit recommendedat full power condition and is the highest value atwhich normal life can be expected.

Pressure LimitsSystem pressure is a dominant operating variableaffecting hydraulic unit life. High pressure, whichresults from high load, reduces expected life in amanner similar to many mechanical assemblies suchas engines and gear boxes. There are load-liferelationships for the rotating group and for the shaftanti-friction bearings.

Maximum pressure is the highest intermittent pres-sure allowed. It is determined by the maximum ma-chine load demand. Maximum pressure is as-sumed to occur a small percentage of operatingtime, usually less than 2% of the total.

Continuous pressure is the average, regularly oc-curring pressure.

Both the maximum and continuous pressurelimits must be satisfied to achieve the expectedlife.

Continuous MaximumProduct Pressure Pressure

Series 70-BD 1000 2100(69) (145)

15 Series 2500 4500(175) (310)

Operation at these pressure limits (under normalconditions) will give a five year life expectancy (@200 hours usage per year), assuming recommendedmaintenance procedures are followed. In the eventthat an extreme duty cycle is anticipated, consultSauer-Sundstrand.

FluidsRatings and data for Sauer-Sundstrand products arebased on operating with premium hydraulic fluidscontaining oxidation, rust, and foam inhibitors.

These premium fluids include API CD engine oils perSAE J183, Type F automatic transmission fluids,power shift transmission fluids meeting Allison C-3 orCaterpillar TO-2 requirements and certain specialtyagriculture tractor fluids. For further information, con-sult Sauer-Sundstrand.

At continuous operating conditions, fluid viscosityshould be above 55 SUS (9 mm2/sec). Minimum fluidviscosity should be above 45 SUS (6.4 mm2/sec) atintermittent operating conditions.

FiltrationA 20 micron (nominal rating) filter should be placed inthe inlet line to the charge pump. The maximumcontinuous inlet vacuum should not exceed 10 in. Hg(0.7 bar abs.); the filter should be replaced when theinlet vacuum exceeds 10 in. Hg (0.7 bar abs.). Duringcold starts, the inlet vacuum may exceed this level.Inlet vacuum at normal operating conditions shouldnot exceed 5 in. Hg (0.8 bar abs.).

Reservoir RequirementsA suggested minimum reservoir volume is 5/8 of thetotal charge pump flow with a minimum fluid volumeequal to 1/2 of the charge pump flow. This allows 30seconds dwell time for removing any entrained air inthe oil. This is adequate for a closed reservoir in mostapplications.

The reservoir outlet to the charge pump inlet shouldbe near the bottom of the reservoir and must alwaysbe covered with fluid. The reservoir inlet (fluid return)from the transmission should be below the fluid leveland be as far away as possible from the outlet port.

Case PressureUnder normal operating conditions, the maximumcontinuous case pressure must not exceed 4 psi (0.3bar) for Series 70-BD units or 10 psi (0.7 bar) for 15Series units. Maximum allowable intermittent casepressure during cold start must not exceed 10 psi(0.7 bar) for Series 70 units or 25 psi (1.7 bar) for 15Series units.

Allowable Pump Input Shaft Side LoadsThe following graphs assume that a self tensioningdevice is used to supply tension to the belt, and thatthe belt tension is proportional to the amount oftorque required to turn the shaft. Since torque isproportional to the system pressure generated, belttension can be determined by knowing the operatingsystem pressure and the pitch diameter of the sheave.

Typical self tension devices apply five times thetension to the tight side of the belt as is applied to theloose side of the belt. The following equations can beused to calculate the belt side load.

The accompanying graph represents the maximumallowable conditions based upon shaft stress. Allexternal shaft loads will have an effect on bearing life.If continuously applied external loads exceed 25% ofthe maximum allowable, contact Sauer-Sundstrandfor unit bearing life evaluation.

Temperature and CoolingThe operating temperature of the transmission shouldnot exceed 180° F (82° C) continuous and 220° F(104° C) intermittent. These temperature limits applyat the hottest point in the transmission, which isnormally the case drain.

Heat exchangers may be installed in the case draincircuit if necessary, and should be sized to keep thefluid within recommended temperature limits. Test-ing to verify that these temperature limits are notexceeded is recommended.

Cold oil will generally not affect durability of thetransmission components, but it may affect the abilityto start the engine, flow oil, and transmit power. Ingeneral, cold starts may be made at a temperature30° F (16° C) above the pour point of the fluid. Theaccompanying graph illustrates the relationship be-tween shaft turning torque at 400 rpm and fluidviscosity.

Auxiliary Mounting Pad (15PV)The 15 Series pump is available with an optional SAE“A” mounting pad for mounting auxiliary hydraulicpumps. Since the auxiliary pad operates under casepressure, an O-ring must be used to seal the auxiliarypump mounting flange to the pad.

The 9 tooth spline has a 450 lbf•in (51 Nm) continu-ous and 950 lbf•in (107 Nm) maximum torque rating.These ratings assume a 58 Rc hardness on themating pump shaft and 0.53 in. (13.5 mm) minimumspline engagement. The continuous torque rating isbased on spline tooth wear.

Mounting Flange Loads (15PT)Subjecting 15 Series tandem pumps to high shockloads may result in excessive loading of the mountingflange. Studs are provided at the rear of the unit forattaching a support bracket.

Direct Displacement Control (DDC)The Direct Displacement Control can be located oneither side of the Series 70 and 15 Series transmis-sion or pump (except the BDP-10L). It provides asimple, positive method of control. Movement of thecontrol shaft causes a proportional swashplate move-ment, thus varying the pump’s displacement from fulldisplacement in one direction to full displacement inthe opposite direction.

Vehicle propel applications may require a provisionfor non-linear control input to reduce control sensitiv-ity near neutral. Damping or frictional forces may benecessary to produce the desired control feel.

These units do not include any neutral centeringdevice for the swashplate. It is necessary to providea force in the machine’s control system that will holdthe swashplate at the desired angle. A “fail safe”design which will return the swashplate to neutral inthe event of linkage failure is recommended.

WARNING

With no external forces applied to the swash-plate trunnion, internal hydraulic forces maynot return the swashplate to the neutral posi-tion under all conditions of operation.

The approximate torque necessary to rotate thecontrol per 1000 psi (70 bar) of system operatingpressure is as follows:

Series 70 BD-10 65 lbf•in per 1000 psi(7.3 Nm per 70 bar)

Series 70 BD-21 100 lbf•in per 1000 psi(11.3 Nm per 70 bar)

15 Series 65 lbf•in per 1000 psi(7.3 Nm per 70 bar)

The maximum torque that should be applied to thecontrol under any condition is as follows:

Series 70 BD-10 200 lbf•in (22.6 Nm)

Series 70 BD-21 400 lbf•in (45.2 Nm)

15 Series 400 lbf•in (45.2 Nm)*

* With a maximum radial force of 100 lbsf (445 N)applied to the control shaft not more than 3 inches(76.2 mm) from the seal surface.

Implement Pump PerformanceThe following graphs provide typical implement pumpperformance information for the Series 70-BDU-21Land the 15 Series units.

BRAKING WARNING

The loss of hydrostatic drive line power in anymode of operation may cause the loss of hy-drostatic braking capacity. A braking system,redundant to the hydrostatic transmissionmust, therefore, be provided which is adequateto stop and hold the system should the condi-tion develop.

Definitions of Typical Lawn and Garden and Turf Maintenance Vehicles

Lawn Tractor – Vehicle with an 8 to 16 horsepower (6to 12 kW) gasoline engine that is used primarily formowing with limited drawbar capability and someactive ground engaging attachments (i.e. rotary tillers,snowblowers). Tire diameters are typically 18 to 20in. (457 to 508 mm) and vehicle weights are generally500 lbs. (227 kg) or less.

Yard Tractor – Vehicle with a 12 to 18 horsepower (9to 13.5 kW) gasoline or diesel engine that is usedprimarily for mowing with some drawbar capabilityand some active ground engaging attachments (i.e.rotary tillers, snowblowers, front blade). Tire diam-eters are typically 20 to 23 in. (508 to 584 mm) andvehicle weights range from 650 to 850 lbs. (295 to386 kg).

Garden Tractor – Vehicle with a 14 to 20 horsepower(10.5 to 15 kW) gasoline or diesel engine that is usedas a mowing or utility vehicle. Capability for usingpassive ground engaging implements such as mold-board plows and front end loaders distinguish thesetractors from yard tractors. Tire diameters are typi-cally 23 to 28 in. (584 to 711 mm) and vehicle weightsrange from 1000 to 1200 lbs. (454 to 544 kg).

Front Mount Mower – Vehicle used primarily formowing, where the mowing attachment is located infront of the machine. Some have accessory attach-ments such as brooms, snowblowers, and blades.The vehicle is usually driven through a transmission/transaxle arrangement and the rear wheels aresteered. Vehicle weights and tire diameters vary inrelation to the size of the mower.

Rear Engine Rider – Vehicle used primarily for mow-ing, where the mower deck is located under themachine. The engine is located at the rear, oftenunder the operator's seat. The vehicle is usuallydriven through a transaxle arrangement and the frontwheels are steered. Tire diameters are typically 18 in.(457 mm) or less, and vehicle weights are generally500 lbs. (227 kg) or less.

Dual Path Mower – Vehicle used primarily for mowingwith some accessory attachment capability. Usuallya dual path propelled vehicle in which steering isdone by controlling the speed of each drive wheelindependently. Vehicle weights and tire diametersvary in relation to the size of the mower.

Component Selection for Lawn and Garden or Turf Maintenance Vehicles

Selecting the proper transmission for a vehicle be-gins with determining the maximum vehicle speeddesired and the maximum tractive effort required.The transmission selected must meet both require-ments.

Many lawn and garden hydrostatic transmissions areused in conjunction with readily available transaxles.The maximum hydrostatic motor speed can be calcu-lated by using the following equation. The inputspeed to the pump should be 10% greater than themaximum motor speed.

Max. Motor Speed (rpm) = S x FDR x 168

LR

Where:S = Maximum Vehicle Speed in mphFDR = Transaxle Final Drive RatioLR = Tire Loaded Radius in inches

A useful parameter for determining tractive effort is“pull ratio”. Pull ratio is a dimensionless term that isthe ratio of tractive effort to gross vehicle weight. It isgenerally constant for each class of vehicle. Thesevalues may be used when actual vehicle tractiveefforts are not known.

Typical Pull Ratios for Lawn and GardenVehicles

Maximum TypicalVehicle Class Pull Ratio Pull Ratio

Lawn Tractor 0.73 0.18

Yard Tractor 0.80 0.20

Garden Tractor 1.00* 0.23

Front Mount Mower 0.80** 0.23

Rear Engine Rider 0.50 0.16

Dual Path Mower 0.85 / 2 0.25 / 2

* Assumes weight transfer to the driving wheelsfrom an implement.

** Based on wheel slip for a four-wheel-drive ve-hicle on dry asphalt. For mower service on turf, aratio of 0.62 may be more appropriate.

2 1


Component Selection (Continued)

Because there are no system pressure relief valvesin Series 70 units and many 15 Series transmissions,the maximum hydrostatic motor torque should occurat the vehicle wheel slip condition. Because of weighttransfer from pushing or pulling implements, it maybe difficult to determine the true weight on the drivewheels at wheel slip. Experience has shown that thevalues listed under “Maximum Pull Ratio” in theabove table can be used to determine the maximumtractive effort. The maximum hydrostatic motor torquecan be calculated using the following equation:

Max. Motor Torque(lbf in) =

Maximum PR x GVW x LR

FDR x FD eff

Where:

PR = Pull Ratio

GVW = Gross Vehicle Weight in lbs.

LR = Tire Loaded Radius in inches

FDR = Transaxle Final Drive Ratio

FD eff = Transaxle Final Drive Efficiency

Vehicles generally operate at the maximum tractiveeffort condition less than 2% of their life, therefore itis necessary to select a transmission which will giveadequate life under typical operating conditions. If aduty cycle for the transmission is known, Sauer-Sundstrand can assist in calculating a weightedaverage or root cubic mean motor torque and canestimate the life expectancy of the transmissionselected.

If the vehicle duty cycle is not known, then the valuesin the accompanying table listed under typical oper-ating conditions can be used in the following equationfor the motor torque determination. If the life is notadequate, the transaxle final drive ratio or tire sizemay need to be changed, or the next larger transmis-sion may be needed. Contact Sauer-Sundstrand forassistance in the correct transmission selection.

Typical Operating Motor Torque (lbf in) =

Typ. PR x GVW x LR

FDR x FD eff

Where:

Typ. PR = Typical Pull Ratio

GVW = Gross Vehicle Weight in lbs.

LR = Tire Loaded Radius in inches

FDR = Transaxle Final Drive Ratio

FD eff = Transaxle Final Drive Efficiency
