The invention discloses a high-strength anti-collision rear axle, and particularly relates to the technical field of electric vehicle rear axles, the electric vehicle rear axle needs to be provided with a corresponding anti-collision mechanism to prevent the rear axle from being collided to generate deformation, and buffer devices need to be arranged at the joint of the electric vehicle rear axle and a hub and the joint of the electric vehicle rear axle and a vehicle frame. The rear axle body comprises two half axle tubes, first springs and second springs are arranged in the two half axle tubes, anti-collision mechanisms are installed at the bottom end and on one side of the rear axle body, each anti-collision mechanism comprises a first arc-shaped elastic block and a second arc-shaped elastic block, damping mechanisms are installed at the top ends of the two half axle tubes, and each damping mechanism comprises a fifth spring. The collision force borne by the wheels is reduced through the first springs and the second springs, the first arc-shaped elastic blocks and the second arc-shaped elastic blocks are collided to generate elastic deformation, the force generated by collision is unloaded to the damping mechanisms, and the rear axle is buffered through the fifth springs.
本发明公开了一种高强防撞后桥,具体涉及电动车后桥技术领域,电动车后桥需要配置相应的防撞机构来防止后桥受到撞击产生形变,且电动车的后桥与轮毂连接处以及与车架连接处需设置缓冲装置,包括后桥本体,后桥本体包括有两个半轴管,两个半轴管内部均设有第一弹簧和第二弹簧,后桥本体底端和其一侧均安装有防撞机构,防撞机构包括有第一弧形弹性块和第二弧形弹性块,两个半轴管顶端均安装有减震机构,减震机构包括有第五弹簧,利用第一弹簧和第二弹簧减少车轮受到的碰撞力,利用第一弧形弹性块和第二弧形弹性块受到碰撞产生弹性形变,并将碰撞产生的力卸载减震机构处,利用第五弹簧对后桥进行缓冲。
