The invention belongs to the technical field of retarders, and particularly relates to an electromagnetic valve control magnetorheological fluid medium retarder loading method which comprises the following steps: when a retarder loads braking force, an unloading valve 01 and an unloading valve 02 are arranged in the retarder, an input port and an output port are respectively connected with a high-pressure cavity and a low-pressure cavity of a mechanical structure cavity of the retarder; a return spring is arranged on the right side of the piston in the valve body, and when no pressure exists on the left side of the piston, the piston is in an open state under the action of the spring. Different from the hydraulic coupling principle of a traditional hydraulic retarder, the hydraulic retarder directly intervenes in the transmission torque of the vehicle through hydraulic pressure, so that the response speed is high, and the hydraulic retarder is compact and simple in mechanical structure, small in overall size and weight and high in response speed.

    本发明属于缓速器技术领域,具体的说是一种电磁阀控制磁流变液介质缓速器加载方法,包括以下步骤:缓速器加载制动力时,缓速器内设有卸荷阀01及卸荷阀02,输入输出口分别连接缓速器机械结构腔体的高低压腔,阀体内活塞右侧带回位弹簧,当活塞左侧没有压力时,活塞在弹簧的作用下呈开启状态,本发明输入轴与变速箱传动轴采用增速降扭齿轮连接,在传动轴转矩的带动下,机械结构在缓速器腔体内产生回转运动,压力变化带动腔内的液体循环流动,实现车辆缓速功能,不同于传统液力缓速器的液压耦合原理,由于本发明是液压直接干预车辆传动转矩,所以反应速度较快,该发明机械机构紧凑简单,整体体积及重量小、反应速度快。
