The invention relates to the technical field of vehicle suspension systems, in particular to a shock absorber. The shock absorber comprises a damper, a spring and a spring supporting plate, wherein the spring supporting plate is further provided with a dynamic rubber ring abutting against the spring; and the position, located on the spring supporting plate, of the starting point of the spring is an initial position, the position, separated from the dynamic rubber ring, of the spring is an ending position, the lift of the spring supporting plate from the initial position to the end position is gradually increased, and the lift of the dynamic rubber ring from the initial position to the end position is gradually increased. According to the shock absorber, the dynamic rubber ring on the spring supporting plate is always attached to the lower end part of the spring in the moving process of a whole vehicle, therefore the situation that a coating of the spring is damaged by gravel due to the fact that a gap is generated between the dynamic rubber ring and the spring can be prevented, and the service life of the spring and the dynamic rubber ring is prolonged. The invention further provides a vehicle suspension. The vehicle suspension comprises the shock absorber and wheels, wherein the initial position of the shock absorber is located on the side, away from the wheels, of a vehicle body in the width direction. The invention further provides a vehicle. The vehicle comprises the vehicle suspension.

    本发明涉及车辆悬架系统技术领域,一种减振器,包括阻尼器、弹簧以及弹簧托盘,弹簧托盘上还设有与弹簧抵接的动态橡胶圈,弹簧的起点位于弹簧托盘的位置为初始位置,弹簧与动态橡胶圈分离的位置为终止位置,弹簧托盘由初始位置至终止位置的升程逐渐增大,动态橡胶圈由初始位置至终止位置的升程逐渐增大。本发明所提供的减振器,弹簧托盘上的动态橡胶圈在整车运动过程中始终与弹簧的下端部贴合,可以防止动态橡胶圈与弹簧之间产生间隙而导致砂石对弹簧的涂层的破坏,延长弹簧和动态橡胶圈的使用寿命。本发明还提供一种车辆悬架,包括减振器和车轮,减振器的初始位置位于车身的宽度方向且远离车轮的一侧。本发明还提供一种汽车,包括上述的车辆悬架。
