The invention discloses a hydraulic retarder driven valve control system which comprises a driven valve 1 and a driven valve 2, and the driven valve 1 and the driven valve 2 are arranged at an outlet and an inlet of a stator cavity and an inlet of a rotor cavity respectively. The oil storage cavity is respectively communicated with the driven valve 1 and the driven valve 2; the variable pump is communicated with the oil storage cavity; the electromagnetic valve is arranged on a pipeline between the oil storage cavity and the driven valve 1 and the driven valve 2, and is used for simultaneously controlling the opening and closing of the driven valve 1 and the driven valve 2; by arranging the two-position three-way electromagnetic valve, compared with a common electromagnetic valve matched with a valve rod structure in the market, the space occupied in the hydraulic retarder is small, the internal space of the retarder is saved, the two driven valves are controlled through the two-position three-way electromagnetic valve, an oil way is simplified, weight reduction and weight reduction are achieved, and meanwhile the cost is reduced. And the response speed during action generation of the brake pedal can be improved.
本发明公开了一种液力缓速器从动阀控制系统,该控制系统包括:从动阀1、从动阀2,所述从动阀1、从动阀2分别设置在定转子腔出口与进口;储油腔,所述储油腔分别与从动阀1、从动阀2连通;变量泵,所述变量泵与所述储油腔连通;电磁阀,所述电磁阀布置在储油腔与从动阀1、从动阀2之间的管路,用于同时控制从动阀1、从动阀2的启闭;通过设置两位三通电磁阀,相对于市面上存在的普通电磁阀配阀杆结构,于液力缓速器内的空间占用少,节省了缓速器内部空间,且通过一个两位三通电磁阀控制的两个从动阀,简化了油路,在实现减重轻量化的同时,便于提高制动踏板动作产生时的响应速度。
