The invention discloses a rear axle shock absorption device, and relates to the technical field of electric vehicle rear axles. The rear axle comprises a rear axle body, fixing sleeves are fixedly connected to the two ends of the rear axle body, a U-shaped fixing frame is fixedly arranged on the sides, close to an output shaft of the rear axle body, of the fixing sleeves, connecting rods are rotatably connected to the two ends of the fixing frame, and two symmetrically-distributed chassis supports are arranged over the rear axle body; the chassis support and the connecting rod are directly provided with a shock absorption assembly, and an anti-scraping assembly is arranged under the rear axle body. Shock absorption is conducted on the chassis support through the first shock absorption rod, the second shock absorption rod, the first sliding block, the second sliding block and the shock absorption spring, the shock absorption type of the chassis support is increased, the situation that when a single shock absorber is arranged for shock absorption, the shock absorber load is large, and consequently the damage degree is sharply increased is avoided, the damage degree of the shock absorber is reduced, and the service life of the shock absorber is prolonged; and the maintenance time is shortened, so that the maintenance cost is reduced.

    本发明公开了一种后桥避震装置,涉及电动车后桥技术领域;而本发明包括后桥本体,所述后桥本体两端固定连接设有固定套,所述固定套靠近后桥本体输出轴一侧固定设有呈U型的固定架,所述固定架两端转动连接设有连接杆,所述后桥本体正上方设有两个对称分布的底盘支架,所述底盘支架同连接杆直接设有避震组件,所述后桥本体正下方设有防刮组件;本发明中通过第一减震杆、第二减震杆、第一滑块、第二滑块和减震弹簧对底盘支架进行避震,增加底盘支架避震型,避免单一设置减震器来进行进行避震时,减震器荷载较大导致损坏程度剧增,降低减震器的损坏程度,延长其使用寿命,降低维护时长,从而减少维修成本。
