The invention discloses a rear axle damping shock absorber of an electric tricycle. The shock absorber comprises a first sleeve and a second sleeve which are coaxially sleeved. The first sleeve comprises an inner pipe and an outer pipe which are coaxially and fixedly arranged; an inner diameter of the second sleeve is not smaller than an outer diameter of the inner pipe; and the outer diameter ofthe second sleeve is not larger than the inner diameter of the outer pipe, a friction sleeve is fixedly arranged on the inner wall of the second sleeve, and the inner wall of the friction sleeve is ininterference fit with the outer wall of the inner pipe. According to the rear axle damping shock absorber of the electric tricycle, internal components are effectively reduced, production cost is reduced, and a problem of medium oil leakage is effectively avoided.
本发明公开了一种电动三轮车后桥阻尼减震器,包括同轴套装的第一套筒和第二套筒,所述第一套筒包括同轴固定设置的内管和外管,所述第二套筒的内径不小于内管的外径,所述第二套筒的外径不大于外管的内径,所述第二套筒的内壁固定设置摩擦套筒,所述摩擦套筒的内壁与内管的外壁之间为过盈配合,本,本电动三轮车后桥阻尼减震器有效减少内部组件,缩减生产成本,且有效避免介质油泄漏的问题。
