The invention belongs to the technical field of vehicles, and particularly relates to a rear power take-off assembly, an engineering vehicle and a control method of the engineering vehicle. The rear power take-off assembly comprises a shell, a gear shaft, an output flange and a pneumatic clutch mechanism, wherein the gear shaft is arranged in the shell in a penetrating mode, and the gear shaft isused for being connected with the output end of an engine; the output flange sleeves the gear shaft, an accommodating cavity is formed among the shell, the output flange and the gear shaft, and an airinlet hole communicating with the accommodating cavity is formed in the shell; and the pneumatic clutch mechanism is arranged in the accommodating cavity, and the pneumatic clutch mechanism is used for controlling the gear shaft and the output flange to be switched between a connecting state and a disconnecting state. According to the rear power take-off assembly, connection or disconnection between the gear shaft and the output flange is controlled through the pneumatic clutch mechanism, so that interruption of power output of the engine is achieved, output power of the engine is effectivelycontrolled, and the situation that an upper air compressor device is in a working state all the time is avoided.

    本发明属于车辆技术领域,具体涉及一种后取力总成、工程车辆及工程车辆的控制方法。所述后取力总成包括:壳体;齿轮轴,所述齿轮轴穿设于所述壳体,所述齿轮轴用于连接发动机输出端;输出法兰,所述输出法兰套设于所述齿轮轴,所述壳体、所述输出法兰与所述齿轮轴之间形成有容纳腔,所述壳体上设有与所述容纳腔连通的进气孔;气动离合机构,所述气动离合机构设置在所述容纳腔内,所述气动离合机构用于控制所述齿轮轴与所述输出法兰在连接状态和断开状态之间切换。根据本发明的后取力总成,通过气动离合机构控制齿轮轴与输出法兰之间的连接或断开,从而实现发动机动力输出的中断,有效控制发动机的输出动力,避免上装空压机装置一直处于工作状态。
