静压传动是泵和马达组成的容积调速系统,靠改变泵或马达的排量来改变马达的转速与扭矩。国外有些装载机使用静压传动作为行走传动系统,如型和TLF—4型装载机。此类传动除具有一般液力传动的特点外,还具有: 1.可实现无磨损、无打滑的启动与加速,因之效率较高,加速性能好,在原动机转速较低时也可利用最大牵引力。 Hydrostatic transmission is a volumetric speed control system composed of a pump and a motor, which changes the speed and torque of the motor by changing the displacement of the pump or the motor. Some foreign loaders use static pressure transmission as a walking drive system, such as type and TLF-4-type loaders. In addition to this type of transmission has the general characteristics of hydraulic transmission, but also has: 1. Can achieve wear-resistant, non-slip start and acceleration, the higher efficiency, acceleration performance, low speed at the original prime mover can also use the maximum Traction.
