The invention provides a shock absorber. The shock absorber comprises a first annular piston and a second annular piston. The piston rod is sleeved with the first annular piston, the first annular piston is tightly connected with the inner wall of the shock absorber inner cylinder, the shock absorber inner cylinder is separated by the first annular piston to form a first air chamber and a second air chamber, and the first air chamber is provided with a first inflation inlet used for being connected with an air source; the second annular piston is assembled in the first cavity and divides the first cavity into a third air chamber and a fourth air chamber, and the third air chamber is provided with a second inflation inlet used for being connected with an air source. According to the shock absorber, the first inflation inlet or the second inflation inlet is communicated with an air source, the first annular piston and the second annular piston are pushed to move, the axial size of the shock absorber can be adjusted to be reduced or increased, the height of a vehicle body can be adjusted to be reduced or increased, and the requirement for rapid adjustment of the height of the vehicle body can be met.

    本发明提供了一种减振器,该减振器包括第一环状活塞和第二环状活塞;所述第一环状活塞套装在所述活塞杆上,所述第一环状活塞与所述减振器内筒内壁紧密相接,所述第一环状活塞分隔所述减振器内筒,形成第一气室和第二气室,所述第一气室上设有用于连接气源的第一充气口;所述第二环状活塞装配在所述第一腔体内,所述第二环状活塞分隔第一腔体,形成第三气室和第四气室,所述第三气室上设有用于连接气源的第二充气口。本发明中,通过给第一充气口或第二充气口接通气源,推动第一环状活塞和第二环状活塞移动,可以调节减振器轴向尺寸的减小或增大,以实现调控车身高度降低或升高,可以满足车身高度快速调节的需求。
