The rotary type hydraulic shock absorber comprises a cylindrical hollow cylinder body and a rotating shaft coaxially arranged in the cylinder body, the cylinder body extends inwards in the radial direction to form a first separating piece, the rotating shaft extends outwards in the radial direction to form a second separating piece, and the first separating piece is connected with the rotating shaft in a sealed and sliding mode. The second partition piece is connected with the cylinder body in a sealed and sliding mode, an inner cavity of the cylinder body is divided into a first cavity body and a second cavity body which are filled with working liquid, and at least one of the first partition piece and the second partition piece is provided with a valve hole for the working liquid to pass through. The invention further discloses a swing arm comprising the rotary hydraulic shock absorber, a suspension structure and a vehicle. According to the rotary hydraulic shock absorber, the movement of the shock absorber can be controlled in the internal space of the cylinder body while the shock absorption effect is achieved, so that the structural length is prevented from being increased, the requirement for the arrangement space is greatly lowered, the difficulty of designing the internal space of a vehicle is lowered, and the application range of the shock absorber is widened.
本申请公开了一种旋转式液压减震器,其包括圆柱体形的空心缸体和同轴地设置在缸体内的转轴,缸体径向向内伸出第一分隔件,转轴径向向外伸出第二分隔件,第一分隔件与转轴密封且可滑动地相接,第二分隔件与缸体密封且可滑动地相接,将缸体内腔分隔出填充有工作液体的第一腔体和第二腔体,并且第一分隔件和所述第二分隔件中的至少一者上设置有可供工作液体通过的阀孔。本申请还公开了包括这种旋转式液压减震器的摆臂、悬架结构及车辆。上述旋转式液压减震器可以在实现减震效果的同时,将减震器的活动控制在缸体内部的空间,从而避免增大结构长度,对布置空间的需求大大下降,降低了车辆内部空间设计的难度,增大了减震器的应用范围。
