CDM - 170: Creep Drive Motor
DRIVING INNOVATION

CDM 170 Creep Drive
3
What is a Creep Drive? • A creep drive is an hydrostatic transmission that will be
installed on an existing mechanical transmission of a truck to allow a regular and relatively slow motion.
• The Creep Drive is installed on the driveline between the truck gear box and the rear axle(s)
4
• In transport mode the creep drive motor is disengaged and the truck uses its mechanical transmission between 0 to 100 km/h (0 to 65 mph)
• In the creep drive mode the mechanical transmission is in neutral. A pump fitted on a PTO drives the Creep Drive motor which is engaged. The truck speed will be from 0 to 8 km/h (0 to 5 mph)

Features and Benefits
Features and benefits of all the Creep Drives• Allows an easy control of a regular continuous low ground speed
without playing with the clutch of the mechanical transmission. ⇒ Cost saving on maintenance.
• Allows hydrostatic braking. No need to use the mechanical brakes. ⇒ Cost saving on maintenance.
• No impact on drivability or efficiency at transport speeds.
• Easily integrated into remote control systems.
• High overall efficiency and excellent starting torque.

Features and Benefits of CDM 170
• Extremely Compact with Drive Through Shaft:– Easy installation. – Minimum design work necessary. – Minimum modification required on the truck.
13
Features and Benefits of CDM 170
• Direct Drive Very High Torque Density Light weight (125Kg):
– Minimum Modification of the truck weight.
• Direct Drive Soft Start:– Increase Driver Comfort;– Better Control of the Vehicle.

HSM + Gear-box Poclain Hydraulics• 1 specific hydraulic fluid for the
gearbox• Fluid level invisible from the
outside of the motor• Frequent and complicated oil
change
• Put and forget– HST fluid is enough
• No Oil Change required:– Reduced maintenance and longer lifetime.
