Abstract
The invention relates to a shock absorber of a motor vehicle. The shock absorber of the motor vehicle comprises an outer tube, an inner tube, a first air chamber and a second air chamber, and the outer tube and the inner tube are connected in a sleeving mode. The outer tube is a solid tube with one end open and the other end closed. The inner tube is a solid tube with two closed ends, and one closed end is provided with a small hole. The end, provided with the small hole, of the inner tube faces the bottom of the closed end of the outer tube, and is plugged into the outer tube from the open end. The first air chamber and the second air chamber are connected inside the inner tube through a partition piston. The first air chamber comprises an outer tube connection bar, a first air chamber main piston and a first air nozzle. One end of the outer tube connection bar is connected to the bottom of the closed end of the outer tube, and the other end of the outer tube connection bar penetrates through the small hole and is connected with the first air chamber main piston inside the inner tube. The first air chamber is communicated with the outside through the through hole, the outer tube connection bar and the first air nozzle which are connected with one another. The second air chamber comprises a second air chamber piston and a second air nozzle. The area, between the second air chamber piston and the partition piston, of the inner side wall of the inner tube is filled with elastic elements.
