The invention relates to a vehicle swing arm bushing which comprises an outer sleeve, an inner sleeve and a vulcanized rubber body vulcanized between the outer sleeve and the inner sleeve. The six large groove rings are designed in the radial direction of the rubber vulcanized body, the six small groove rings are additionally arranged among the large groove rings, and the effect of adjusting rigidity is achieved through the groove rings of different sizes so that small-amplitude vibration is isolated, a large impact in the Y direction during acceleration and braking is relieved, limitation of the bushing is guaranteed, movement of a swing arm is well limited, the service life of the rubber bushing is prolonged, and the control stability, smoothness and NVH performance of the automobile are facilitated. The bushing has the advantages of being simple in structure, light in weight, large in radial rigidity, small in torsional rigidity, capable of buffering impact, capable of limiting and comfortable in riding.
本发明涉及一种车辆摆臂衬套,包括外套管、内套管及硫化于外套管和内套管之间的硫化橡胶体。通过在橡胶硫化体径向设计有六个大槽环,在大槽环间增加了六个小槽环,通过大小不等的槽环,起到调节刚度的作用,从而隔绝小幅度的振动,缓和加速、制动时Y向大的冲击,保证衬套限位,很好地限制摆臂的运动,在提高橡胶衬套寿命的同时,有利于汽车的操纵稳定性、平顺性和NVH性能。此衬套具有结构简单,重量轻,径向刚度较大,扭转刚度较小,缓和冲击,限位和乘坐舒适的优点。
