A motor vehicle shock absorber

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.

Description

technical field [0001] The present invention relates to a shock absorber, more particularly, to a motor vehicle shock absorber. Background technique [0002] Shock absorbers are widely used in automobiles and locomotives. They can absorb the impulse generated during car washing and locomotive braking to achieve a buffering effect, so as to improve riding comfort and driving safety. Traditional shock absorbers, whether they are metal springs or gas springs, have the disadvantage of being unable to adjust the stroke freely, and generally require a more complicated structure, or need to change the length of the shaft of the shock absorber, the length of the metal spring or The purpose of changing the stroke is achieved by changing the length of the air chamber tubing of the air pressure spring. These methods are relatively complicated, and the implementation is difficult and costly. Contents of the invention [0003] The technical problem to be solved by the present inventio...

Traditional shock absorbers, whether they are metal springs or gas springs, have the disadvantage of being unable to adjust the stroke freely, and generally require a more complicated structure, or need to change the length of the shaft of the shock absorber, the length of the metal spring or The length of the gas chamber tubing of the air spring is used to change the stroke. These methods are relatively complicated, and the implementation is difficult and costly.
