Inner curve hydraulic motor

characteristic

1. The overall structure is designed in a modular manner, with stacked pieces and divided into mechanical output modules and hydraulic power modules

The energy module, flow distribution module, and mechanical braking module are four parts that can be easily optimized and matched with various hosts.

2. The use of flat flow distribution technology has low sensitivity to pressure and temperature, automatically compensates for wear between flow distribution friction pairs, and can ensure high volumetric efficiency of the motor for a long time. At the same time, it adopts a roller and plunger structure, with a simple force transmission structure and fewer friction pairs, improving mechanical efficiency.

3. Compared with the QJM series motor, it uses rollers and plungers instead of steel balls and ball plugs; By optimizing the design of the stator curve, while ensuring no pulsation in output torque and speed, the contact stress of the stator is reduced. New materials and processes are used to manufacture the stator, greatly increasing the working pressure of the hydraulic motor. The maximum pressure can reach 40MPa. Due to the small inertia of the transmission mechanism, the plunger pair has a sealed piston ring, and the roller stopper uses anti friction materials, the starting efficiency is high, the low-speed performance is good, and the minimum stable speed is ≤ 0.5rpm

4. Adopting an independent mechanical output module and a large diameter output shaft and bearing, the motor can withstand large axial and radial forces and can be directly connected to the gear output or installed on the vehicle's drive wheels

5. Adopting a modular disc mechanism that can stack mechanical braking devices to achieve direct output shaft

Safety braking and parking braking

6. Motors are divided into single displacement motors and dual displacement motors. Single displacement motors have full displacement output, and the displacement of dual displacement motors can be controlled through control valves to achieve full displacement and half displacement output for speed control.
