1. Product Overview
TheZTM06(9) TRAVEL MOTOR ASSYis an integrated hydraulic travel motor assembly widely used in the chassis drive systems of construction machinery (e.g., excavators, loaders, drilling rigs). Its core function is to convert hydraulic energy into mechanical energy to drive vehicle movement or steering. The model designation "ZTM" typically represents the manufacturer or product series, while "06(9)" may indicate displacement class or compatible machine specifications.
2. Key Technical Specifications
【表格】
Parameter Typical Value/Range Description
Displacement 6 mL/rev to 9 mL/rev Volume of hydraulic fluid discharged per revolution, directly affecting torque output.
Rated Pressure 25–35 MPa Maximum operating pressure under normal conditions; must match hydraulic pump output.
Peak Pressure ≤40 MPa Short-term allowable maximum pressure for overcoming transient loads.
Speed Range 0–150 rpm Adapts to varying travel speed requirements across work conditions.
Torque Output 50–120 Nm (pressure/displacement-dependent) Torque = Displacement × Pressure × Efficiency; critical for climbing and traction.
Brake Type Wet multi-disc/spring brake Wet brakes suit frequent starts/stops; spring brakes provide emergency stopping.
Rotation Direction Bidirectional (reversible) Supports forward, reverse, and steering functions.
3. Structural Components
• Hydraulic Motor Section:
• Piston or gear design (ZTM06(9) typically uses high-pressure piston motors).
• Key parts: port plate, cylinder block, pistons for efficient fluid distribution.
• Reduction Gearbox:
• Planetary gear system to reduce speed and increase torque.
• Alloy steel gears with surface hardening for wear resistance.
• Brake System:
• Wet multi-disc brake: hydraulically released, spring-applied for frequent operation.
• Brake torque must meet full-load safety stop requirements.
• Housing & Seals:
• Aluminum or cast iron housing for structural strength and heat dissipation.
• Dual seals (O-ring + lip seal) prevent oil leakage and external contamination.
