The invention discloses a rear axle assembly of an electric tricycle, and belongs to the technical field of vehicle rear axles. The rear axle assembly comprises an underframe and a rear axle body; the rear axle body comprises a rear axle rod body, and a motor is connected to the rear axle body; the underframe is of a rectangular frame structure, the two ends of the underframe are symmetrically and fixedly connected with a pair of vertical plates, the upper ends of the vertical plates are perpendicularly and fixedly connected with a transverse plate, the side faces of the vertical plates are each rotationally connected with a swing arm, one end of the swing arm is fixedly connected to a rear axle rod body through a locking sleeve, the swing arm is hinged to the locking sleeve, and a spring damper is hinged between the transverse plate and the swing arm; a reinforcing plate is fixedly connected in the underframe, and the lower surface of the reinforcing plate is connected with an anti-collision plate. According to the rear axle assembly, the spring damper is connected between the rear axle rod body and the vertical plate, so that the shock absorption performance of the rear axle is improved, meanwhile, the anti-collision performance of the rear axle assembly is improved through the anti-collision plate, and the rear axle assembly is protected.

    本发明公开了一种电动三轮车的后桥组件,属于车辆后桥技术领域,本发明包括底架和后桥本体;后桥本体包括后桥杆体,后桥本体上连接有电机;底架呈矩形框体结构,底架两端对称固定连接有一对竖板,竖板上端垂直固定连接一横板,竖板侧面均转动连接一摆动臂,摆动臂的一端通过一锁紧套固定连接在后桥杆体上,摆动臂与锁紧套铰接,且横板与摆动臂之间铰接一弹簧减震器;底架内固定连接有加强板,加强板下表面连接有防撞板。本发明通过在后桥杆体和与竖板之间连接由于弹簧减震器,提高了后桥的减震性能,同时防撞板提高了后桥组件的防撞性能,对后桥组件起到保护的作用。
