A shear type rear suspension damping cushion assembly comprises a vehicle body, a lock body assembly is arranged on one side of the lower portion of the vehicle body, a U-shaped bracket is arranged below the lock body assembly, a threaded rod is connected to the middle of the U-shaped bracket in an inserted mode, a rear suspension cushion assembly is connected to the lower portion of the threaded rod in a sleeved mode, and the rear suspension cushion assembly comprises an inner cylinder. The upper end of the inner cylinder is sleeved with an upper guide block, the upper guide block is fixedly connected with the U-shaped bracket, a damping ring is arranged on the portion, located below the upper guide block, of the inner cylinder, an outer cylinder is arranged on the outer side of the damping ring, the outer side of the outer cylinder is sleeved with an outer fixing block, and a lower cushion block is arranged on the portion, located below the damping ring, of the inner cylinder. The vulcanization length of the damping ring and the inner cylinder is large, the pulling-out force between the damping ring and the inner cylinder is increased, the damping ring and the outer cylinder are not prone to being separated, vibration caused by road excitation and engine work can be effectively absorbed, the damping performance is improved, meanwhile, the rigidity in the X direction and the Y direction is large, and the operation stability is improved.
一种剪切式后悬减振软垫总成,包括车身,所述车身下方一侧设有锁体总成,所述锁体总成下方设有U型托架,所述U型托架中部插接有螺纹杆,所述螺纹杆下方套接有后悬置软垫总成,所述后悬置软垫总成包括内筒,所述内筒上端套接有上导向块,所述上导向块与U型托架固定连接,所述内筒位于上导向块下方设有减震环,所述减震环外侧设有外筒,所述外筒外侧套接有外固定块,所述内筒位于减震环下方设有下垫块。本发明减震环与内筒硫化长度大,增加了减震环与内筒之间的拉脱力,减震环和外筒不易分离,可有效吸收来自路面激励和发动机工作带来的振动,提高减振性能,同时X,Y向刚度大,提高了提高操稳性能。
