The invention provides a rear power take-off assembly and a brake control method of the rear power take-off assembly, the rear power take-off assembly comprises an output assembly, an input assembly, a clutch and a brake ring, and the brake ring provides acting force opposite to reset force for a driving mechanism when a friction plate assembly is separated. The brake control method comprises the steps that first pushing force of the driving mechanism on a friction plate assembly of the clutch is controlled, so that the friction plate assembly is separated under the action of reset force of the reset mechanism; receiving an input shaft rotating speed and an output shaft rotating speed of the clutch; calculating a first speed difference according to the input shaft rotation speed and the output shaft rotation speed; and the driving mechanism is controlled according to the speed difference to enable friction plate assemblies of the clutch to tend to be combined or separated. According to the control method, the rotating speed of the clutch is monitored, and then the controller judges the drag force of the load according to the rotating speed difference of the clutch and controls the clutch to be combined or separated according to the drag force, so that the brake ring is protected when the load drag force is large, and the rear power take-off assembly is braked in time when the load drag force is small.

    本发明提出了一种后取力总成和一种后取力总成制动控制方法,后取力总成包括输出组件、输入组件、离合器和制动环,制动环在摩擦片组件分离时对驱动机构提供与复位力反向的作用力。制动控制方法包括步骤:控制驱动机构对离合器的摩擦片组件的第一推动力,使摩擦片组件在复位机构的复位力作用下分离;接收离合器的输入轴转速和输出轴转速;根据输入轴转速和输出轴转速计算第一速差;根据速差控制驱动机构使离合器的摩擦片组件趋向结合或分离。该控制方法通过监测离合器的转速,进而控制器根据离合器的转速差判断负载的拖曳力大小,根据拖曳力大小控制离合器结合或分离,以在负载拖曳力较大时保护制动环,在负载拖曳力较小时及时制动后取力总成。
