The invention provides a rear power take-off assembly and an agricultural vehicle, the rear power take-off assembly comprises an output assembly, an input assembly, a clutch and a brake ring, the clutch comprises a friction plate assembly, a driving mechanism and a reset mechanism, and the driving mechanism can drive the friction plate assembly to combine so as to enable the input assembly to be in transmission connection with the output assembly; or the friction plate assembly is driven to be separated so that the transmission connection between the input assembly and the output assembly can be disconnected, and the reset mechanism transmits reset force enabling the friction plate assembly to tend to be separated through the driving mechanism; the brake ring provides acting force opposite to the reset force for the driving mechanism when the friction plate assembly is separated. When the clutch is separated, the driving mechanism is in surface contact with the brake ring, the pressure of the brake ring comes from the reset force of the reset mechanism of the clutch, the reset force is several times larger than the original brake spring force, and the contact surface is also enlarged, so that the brake torque is increased, the rotation of the output shaft can be stopped in time, and the safety problem is avoided.

    本发明提出了一种后取力总成和一种农业车辆,后取力总成包括输出组件、输入组件、离合器和制动环,离合器包括摩擦片组件、驱动机构和复位机构,驱动机构能够驱动摩擦片组件结合以使输入组件与输出组件传动连接,或者驱动摩擦片组件分离以使输入组件断开与输出组件的传动连接,复位机构通过驱动机构传递使摩擦片组件趋向分离的复位力;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。当离合器分离时,驱动机构与制动环发生面接触,制动环的压力来自离合器的复位机构的复位力,复位力比原来的制动弹簧力大数倍,并且接触面也扩大,使得制动扭矩增大,进而能够及时停止输出轴的转动,避免发生安全问题。
