Worldwide on Track.

Drive Systems for Rail Applications

Urban railways or trams, metros, regional

railcars, locomotives or high-speed trains

and special rail vehicles: Voith offers drive

components and systems solutions for

all rail vehicles.

The Voith portfolio covers all components of the drivelines:

from a wide range of transmissions, diesel engines, cardan

shafts and couplers to complete wheelsets, traction inverters,

cooling systems and waste heat recovery systems to motor-

gear units, Powerpacks and energy absorption elements. No

other supplier has such a comprehensive overall competency

in the driveline. Decades of experience and meticulous

research make us an expert partner for individual require-

ments.

Internationally networked for excellent service

Voith meets local production demands – in Europe, as well as

in China and in the USA. Whatever the country of application,

our customers receive local service and support – be it during

construction, maintenance and service or repairs of their vehicles.

Our spare parts are available quickly and all over the world.

Systems supplier – everything from one single source

As a systems supplier we offer complete solutions to our cus-

tomers. Voith looks after the complete design, assumes systems

responsibility and is thus the sole contact. Apart from logistics

benefi ts, this also results in shorter delivery times. Reduced

interfaces ensure fewer adaptation processes.

Maximum speeds of up to 700 km/h

Worldwide trains with our transmissions achieve maximum

scheduled speeds. The current top speed with a Voith trans-

mission achieved in trial operation on a test stand is at 700 km/h.

Reliability is What Drives Us.

Hi-Tech Engineering, Measuring and Production Methods

Voith offers complex engineering services

already during the planning stage of the

driveline. Our products meet the highest

demands on quality, safety and reliability.

On a production surface of 15 000 square meters Voith

produces mechanical drives for rail vehicles at the location

Heidenheim. The assembly runs in a strict cycle: every 1.2

hours a complete gear unit leaves the production hall. World-

wide, Voith has assembly capacities for over 10 000 gear units

per year.

Engineering methods for optimum design

We use state-of-the-art CAD-3D for the construction of the

gear units and complete wheelsets and optimize interfaces to

adjoining components in the bogie. The fi nite element method

helps us to determine loads within the component and to

achieve targeted perfection of all structures. With this and

other engineering processes, for example multi-body simulation,

we develop constructions and products that meet all anticipated

stress loads and have an optimum weight.

Prototypes tested under maximum load

Prototypes are tested intensively. This includes tests under

load, as well as measurements of the noise and vibration

behavior. In the environmental chamber, the transmissions

are put on the test stand and are examined under extreme

temperatures. Each transmission undergoes a series test run

before it leaves the Voith plant.

Competency in material use

For special applications that require an even lower transmission

weight, Voith produces gear units with weight-saving aluminum

housings. Many of our components also undergo special

surface and hardness treatments, in order to ensure optimum

strength and wear characteristics. Be it for specifi c customer

requirements or for standard applications – our materials meet

the highest demands.

Complete Wheelsets From OneSingle Source

The Voith production line for complete wheelsets offers many

advantages to vehicle manufacturers. We are the only trans-

mission supplier to offer complete wheelsets from one single

source. Out wheelsets comprise gear unit, gear shaft, wheels,

as well as brake disks and wheelset bearings and are individually

adapted to the respective requirements. Urban rails and trains,

metros, regional railcars, high-speed trains, locomotives of

special rail vehicles – the individual components of the complete

wheelset are perfectly matched.

Shorter production times and increased safety

With the Voith wheelset press at the location of our trans-

mission production plant in Heidenheim-Mergelstetten we have

fi nalized our systems competency for complete wheelsets. The

new machine can press all types of wheelsets. Vehicle manu-

facturers thus enjoy up to four weeks shorter production times

and benefi t from increased safety - because we assume full

responsibility for each wheelset, including design, assembly and

testing of all components, as well as for the entire logistics

chain.

Voith wheelset press: up to 315 tons of pressure

The Voith wheelset press has been designed for gauge widths

from 750 to 1 676 millimeters and a maximum wheelset mass of

7.5 tons. With the two-cylinder RADS 2-315 press built by AE,

wheels can be joined together at a pressure of up to 315 tons.

The wheel sides are mounted consecutively, checked for coun-

ter pressure after a rest period and then measured. Customers

receive a protocol documenting all processes stated in compli-

ance with EN Norm 13260.

Seamless Dynamics.

Motor-Gear Units for all Applications

We offer complete electric drivelines as motor-gear units

(MGU) for all trams, urban and standard-gauge railways. We

supply everything from one single source, from motor and

gear units to wheelsets – one supplier for the entire system.

We implement individual solutions and, apart from providing

the electric know-how, utilize our comprehensive experience

with transmissions and wheelsets.

The interface transmission-motor is perfectly adapted and

allows dynamic drive characteristics at all operating condi-

tions. The motor-gear units are particularly reliable and allow

easy maintenance. Due to their compact design, they can be

easily installed and removed.

Service across the entire product life cycle

Voith assumes the complete engineering of the motor-gear

unit from systems design, calculation of the operating cycle

and systems specifi cation to construction, verifi cation, testing

and integration into the vehicle bogie. In addition, we carry out

the service and the maintenance of the units, for which Voith

is the sole contact rather than several different suppliers.

Designed for Maximum Performance.

Gear Units for any Application

Gear units from Voith are operating reliably all over the world.

They are weight and noise-optimized and allow speeds of over

400 km/h. We offer gear units that are optimally adapted to

individual axle loads, speeds and tractive efforts for all rail

vehicles – urban railways and trams, metros, regional railcars,

locomotives, high-speed trains and special rail vehicles.

High-performance components for any drive

Our gear units for transverse or longitudinal drives excel by

quality, reliability, high power density and proven design. Voith

offers single and double-stage helical and bevel gears. They

are available in axle mounted and, for extra protection of

vehicle and track bed, also in fully sprung design.
