Function & Operation
The travel device performs three critical functions:
Function
Description
Propulsion
Converts hydraulic pressure into rotational torque to drive the track sprocket
Speed Reduction
Multi-stage planetary gears reduce speed while multiplying torque for powerful traction
Braking
Spring-applied multi-disc brake holds the machine securely when parked or on slopes
Operating Principle
- Hydraulic oil from the control valve enters the travel motor
- The motor converts oil flow into rotational force
- Planetary gear sets reduce speed and multiply torque
- Final torque drives the sprocket and track
- When controls are centered, the brake automatically engages
Common Failure Signs
Symptom
Likely Cause
