The invention discloses a retarder unloading control method controlled through an electric pump and an electromagnetic valve. Comprising a retarder, a perforated plate electromagnetic control coil, a heat exchanger, a cooling system, an oil storage tank, a first electromagnetic valve, an electric variable pump, a safety valve, an oil inlet one-way valve, an unloading valve, a second electromagnetic valve, a third electromagnetic valve, a retarder high-pressure cavity, a retarder low-pressure cavity, a pressure sensor P2, a temperature sensor T1, a temperature sensor T2 and a pressure sensor P1. In the no-load unloading stage, the pressure of the working cavity is reduced, so that the output torque of the retarder is reduced under the condition that a vehicle is shifted down or braking force is not needed. The controller achieves the purpose of unloading the system by controlling the auxiliary variable pump, the electromagnetic valve and the perforated plate electromagnetic coil.

    本发明公开了一种通过电动泵及电磁阀控制的缓速器卸荷控制方法,包括缓速器、多孔板电磁控制线圈、换热器、冷却系统、储油箱、第一电磁阀、电动变量泵、安全阀、进油单向阀、卸荷阀、第二电磁阀、第三电磁阀、缓速器高压腔、缓速器低压腔、压力传感器P2、温度传感器T1、温度传感器T2、压力传感器P1;本发明空载卸荷阶段是降低工作腔压力,从而在车辆减档或不需要制动力的情况下,降低缓速器输出扭矩的过程。控制器通过对辅助变量泵、电磁阀和多孔板电磁线圈的控制,达到为系统卸荷的目的。
