Control system of travel motor and vehicle
The invention discloses a travel motor control system and a vehicle. The travel motor control system comprises a variable valve and an electromagnetic pressure reducing valve, an oil inlet of the electromagnetic pressure reducing valve is communicated with the high-low pressure oil way; an oil outlet of the electromagnetic pressure reducing valve is connected with a pilot port of the variable valve; a self-feedback pressure port of the variable valve is communicated with a brake cavity of the travel motor; when the variable valve is located at the left position, the pressure relief oil inlet of the variable valve is communicated with the variable piston cavity of the travel motor, and the pressure relief oil outlet of the variable valve is communicated with the pressure relief oil way; when the variable valve is located at the right position, a high-pressure oil inlet and a low-pressure oil inlet of the variable valve are communicated with the first high-pressure oil way and the second high-pressure oil way, and a high-pressure oil outlet and a low-pressure oil outlet of the variable valve are communicated with the variable piston cavity. The pilot pressure of the variable valve can be adjusted by adjusting the output oil pressure of the electromagnetic pressure reducing valve, so that the pressure of the displacement switching point of the travel motor can be adjusted, and the requirements of various working conditions can be met.
本发明公开了一种行走马达的控制系统及车辆，包括：变量阀和电磁减压阀；电磁减压阀的进油口与高低压油路连通；电磁减压阀的出油口与变量阀的先导口连接；变量阀的自反馈压力口与行走马达的制动腔连通；当变量阀位于左位时，变量阀的泄压进油口与行走马达的变量活塞腔连通，变量阀的泄压出油口与泄压油路连通；当变量阀位于右位时，变量阀的高低压进油口与第一高低压油路和第二高低压油路连通，变量阀的高低压出油口与变量活塞腔连通，通过设置电磁减压阀位于高低压油路与变量的先导口之间，使得可以通过调节电磁减压阀的输出油压调节变量阀的先导压力，从而实现对行走马达的排量切换点的压力的可调，能够满足多种工况需求。
