The invention provides a buffer, a suspension system and a vehicle, relates to the technical field of vibration reduction, and aims to solve the technical problem of poor reliability of a bidirectional buffer. The buffer comprises a cylinder body, a piston and a piston rod. The cylinder body is provided with a closed end and an open end which are opposite. The piston is slidably arranged in the cavity of the cylinder body, and the part, located between the piston and the closed end, of the cavity is used for storing gas; the buffer further comprises a reset element arranged on the piston rod in a sleeving mode and a sleeve. The reset element and the sleeve are distributed in the direction away from the piston. Wherein the sleeve is slidably arranged on the piston rod; the buffer further comprises a first limiting structure close to the opening end, and the first limiting structure is provided with a first annular structure protruding out of the inner wall of the cavity. The outer diameter of the sleeve is larger than the inner diameter of the first annular structure. The two-way buffer is used for two-way buffering of a buffering object, the gas leakage risk can be avoided, and then the reliability of the buffer is improved.
本发明提供了一种缓冲器、悬挂系统、车辆,涉及减振技术领域,以解决双向缓冲器可靠性差的技术问题。该缓冲器包括缸体、活塞以及活塞杆,缸体具有相对的封闭端和开口端;活塞滑动设在缸体的腔体中,腔体位于活塞与封闭端之间的部分用于存储气体;缓冲器还包括套设在活塞杆上的复位元件以及套筒,复位元件与套筒沿着远离活塞的方向分布;其中,套筒滑动设在活塞杆上;缓冲器还包括靠近开口端的第一限位结构,第一限位结构具有凸起于腔体内壁的第一环状结构;套筒的外径大于第一环状结构的内径。本发明用于缓冲对象的双向缓冲,可以避免气体泄露风险,进而提高缓冲器的可靠性。
