The invention discloses a control method for controlling loading of a magnetorheological fluid medium retarder through a variable pump, and the control method comprises the following steps: an electromagnetic valve 01 is electrified, and the retarder is converted into a loading state from an unloaded state; the retarder is controlled to be loaded to enter an oil supplementing state, namely the electromagnetic valve 02 is controlled to be powered on; the retarder is controlled to be loaded to enter a torque increasing state, and an electromagnetic valve 02 and an electromagnetic coil are controlled according to a mechanical system pressure threshold value of the retarder; the retarder is controlled to be loaded to enter a torque reduction state, and an electromagnetic valve 02 and an electromagnetic coil are controlled according to a mechanical system pressure threshold value of the retarder; under the control of the variable oil pump, the electromagnetic valve and the electromagnetic coil, pressure is applied to the unloading valve A and the unloading valve B, so that the unloading valves are in a closed state, a cavity of a mechanical system of the retarder is closed to generate pressure, braking force is finally generated, and under the control of the variable oil pump, the electromagnetic valve and the electromagnetic coil, braking force is generated. And the liquid supplementing state, the torque increasing state and the torque reducing state of retarder loading are adjusted.

    本发明公开了一种利用变量泵控制磁流变液介质缓速器加载的控制方法,该控制方法包括以下步骤:电磁阀01通电,缓速器由未加载状态转变为加载状态;控制缓速器加载进入补油状态,即控制电磁阀02通电;控制缓速器加载进入增扭状态,根据缓速器机械系统压力大小阈值,控制电磁阀02及电磁线圈;控制缓速器加载进入减扭状态,根据缓速器机械系统压力大小阈值,控制电磁阀02及电磁线圈;在变量油泵、电磁阀与电磁线圈的控制下,对卸荷阀A、卸荷阀B施加压力,使卸荷阀呈关闭状态,进而使得缓速器机械系统腔体密闭产生压力,最终产生制动力,且通过对变量油泵、电磁阀与电磁线圈的控制下,调节缓速器加载的补液状态、增扭状态、减扭状态。
