Shock absorber for motor vehicle with dual air chamber

Abstract

The invention relates to a shock absorber for a motor vehicle with dual air chamber. The shock absorber for the motor vehicle with the dual air chamber comprises an outer pipe and a first air chamber and a second air chamber of an inner pipe which are sleeved with one another. The outer pipe is a hard pipe with one close end and one open end. The inner pipe is a hard pipe with two close ends. A tiny hole is formed in a close opening in one end. The end, provided with the tiny hole, of the inner pipe faces the bottom of the close end of the outer pipe and is inserted into the outer pipe through the open end. The first air chamber and the second air chamber are arranged in the inner pipe in a connected mode through a separating valve. The first air chamber comprises an outer pipe connecting rod, a main piston of the first air chamber and a first air mouth. One end of the outer pipe is connected to the bottom of the close end of the outer pipe, and the other end of the outer pipe penetrates through the tiny hole and is connected with the main piston of the first air chamber arranged in the inner pipe. The first air chamber is connected with the external through a through hole, the outer pipe connecting rod and the air mouth which are connected with one another. The second air chamber comprises a second air chamber piston and a second air mouth. The second air chamber piston, the closed end without the through hole of the inner pipe and the inner wall of the inner pipe form the second air chamber.

Description

technical field [0001] The present invention relates to a shock absorber, more specifically, to a double air chamber 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 t...

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.
