Reverse pressure control method, hydraulic walking system and railway maintenance machine
The invention discloses a reverse pressure control method, a hydraulic walking system and a railway maintenance machine, and relates to the technical field of hydraulic control. According to the reverse pressure control method, the current of the walking pump and the oil inlet and the oil outlet of the walking motor are controlled according to the brake pressure maintaining time and the outlet pressure of the walking motor, and a hydraulic control reverse brake cartridge valve set does not need to be arranged for controlling the displacement of the pump. Therefore, the problem that the reverse pressure of a system loop is increased due to braking or downhill of a vehicle can be effectively avoided, and the cost of the hydraulic walking system is effectively reduced.
本发明公开了一种反向压力控制方法、液压行走系统及铁路养护机械，涉及液压控制技术领域。反向压力控制方法中根据制动压力维持时间以及走行马达的出口压力对走行泵的电流以及走行马达的进、出油口进行控制，不需要设置液控反向制动插装阀组用于控制泵的排量，便可以有效避免因制动或车辆下坡造成的系统回路反向压力升高的问题，有效降低了液压行走系统的成本。
