The excavator travel assembly is the core component for machine movement, consisting of a hydraulic motor, reduction gearbox, sprocket, track chain, idler wheel, carrier roller, and track roller. Its key function is to convert hydraulic energy into mechanical power, enabling stable mobility across challenging terrains.
Hydraulic Power Transmission
The hydraulic pump transforms engine power into high-pressure oil, which is transmitted to the travel motor via hydraulic lines.
The travel motor converts hydraulic energy into rotational kinetic energy, generating high-speed, low-torque output.
Speed Reduction & Torque Amplification
The gearbox reduces motor speed through gear sets while significantly increasing torque, ensuring sufficient traction force for the sprocket.
Track Drive Mechanism
The sprocket engages with track links to drive the track chain. Carrier rollers and track rollers form a closed-loop track system, while the idler wheel adjusts track tension.
Differential control of dual travel motors enables forward/reverse movement, steering, and zero-radius rotation.
