The invention discloses a shock absorber, a packaging method of the shock absorber and a vehicle, and belongs to the technical field of shock absorption. The shock absorber is high in reliability and comprises a sleeve, a corrugated pipe assembly, a piston assembly and a piston rod, the two ends of the sleeve are provided with a first sealing piece and a second sealing piece respectively, the first sealing piece is provided with a mounting hole penetrating in the axis direction of the sleeve, and a first inner cavity filled with first fluid is formed between the first sealing piece and the second sealing piece; the corrugated pipe assembly is arranged in the sleeve and is subjected to the pressure action of the first fluid, the corrugated pipe assembly can stretch out and draw back along the axis when the pressure changes, the inner space of the corrugated pipe assembly can be adjusted through stretching out and drawing back so as to buffer pressure changes, and the inner space is independent of or communicated with the first inner cavity; the piston assembly is arranged in the first inner cavity and can move in the axis direction, and a circulation structure is arranged on the piston assembly; the piston rod penetrates through the mounting hole and is connected with the piston assembly, a sealing element is arranged between the mounting hole and the piston rod, and the piston rod is driven to move in the sleeve to change the pressure.
本发明公开了一种减震器及其封装方法和一种车辆,属于减震技术领域。该减震器可靠性高,包括套筒、波纹管组件、活塞组件和活塞杆,套筒两端分别设置有第一密件和第二密封件,第一密封件设置有沿套筒的轴线方向贯穿的安装孔,第一密封件和第二密封件间形成有填充第一流体的第一内腔;波纹管组件设置于套筒内并受第一流体的压力作用,且在压力变化时可沿轴线伸缩,该伸缩可调整波纹管组件的内部空间以缓冲压力变化,并且内部空间独立于或连通于第一内腔;活塞组件设置于第一内腔内并可沿轴线方向移动,活塞组件上设置有流通结构;活塞杆穿设于安装孔并与活塞组件连接,且安装孔与活塞杆之间设置有密封元件,活塞杆受驱在套筒内移动以改变该压力。
