The invention discloses an impact-resistant rear axle assembly of an electric tricycle. The impact-resistant rear axle assembly comprises a rack and a rear axle body connected through a spring assembly. The rear axle body is connected with a transmission assembly through a linkage assembly, the transmission assembly is arranged in the rack and is in transmission connection with a locking assembly, and the locking assembly clamps or separates the spring assembly through the transmission assembly. The sliding blocks connected to the two ends of the spring assembly and the fluted discs fixedly connected to one ends of the sliding blocks are engaged with or separated from the locking assembly, and the anti-disengaging assembly is matched to stably lock the impacted end of the spring assembly, so that the sliding blocks connected to the other ends of the spring assembly move in the fixed direction along the rectangular frame. Impact on the rear axle body is released when the spring assembly is in a movable state, and the phenomenon that the rear axle body and the spring assembly are damaged after being impacted is reduced.

    本发明公开了一种电动三轮车的抗冲击型后桥总成,包括机架以及通过弹簧组件连接的后桥本体;后桥本体通过连动组件连接有传动组件,且传动组件设于机架内并传动连接有锁合组件,锁合组件通过传动组件对弹簧组件夹持或分离,本发明中,通过连动组件带动传动组件沿矩形框定向运动,传动组件带动锁合组件启闭,使得弹簧组件两端所连接的滑动块,以及位于滑动块一端固定连接的齿盘与锁合组件咬合或分离,配合防脱组件对弹簧组件受冲击端锁止稳定,实现弹簧组件另一端所连接的滑动块沿矩形框定向运动,将后桥本体受到的冲击在弹簧组件可活动的状态下释放冲击力,降低后桥本体以及弹簧组件受冲击后出现损坏的现象。
