Abstract

The invention discloses a load self-adaption type stroke dependent variable-damping shock absorber. In order to solve the problems that when car loads change, an existing stroke dependent shock absorber cannot fully exert the advantages of a shock absorber, and even the car driving smoothness is reduced, the variable-damping shock absorber comprises a shock absorber body, an air spring (4), a pneumatic adjusting device and a pneumatic execution mechanism. The air spring (4) is mounted at the top end of the shock absorber body and arranged on a piston rod (3) in a sleeving manner. An air channel valve body (7) in the pneumatic adjusting device is mounted on an inner barrel (23) of the shock absorber body, and a plunger (17) is mounted in the inner barrel (23). The upper end of the plunger (17) is in sliding fit with the air channel valve body (7), and the lower end of the plunger (17) is in sliding fit with the bottom end of the inner barrel (23). The air spring (4) is connected with an air pipe (31) of the pneumatic execution mechanism through an air outlet in an upper top cover (2) of the shock absorber body. The air pipe (31) is connected with a horizontal air channel of the air channel valve body (7) through a solenoid valve (30).

Description

technical field [0001] The invention relates to a device in the technical field of automobile chassis, more precisely, the invention relates to a load-adaptive stroke-dependent variable damping shock absorber suitable for various vehicle suspension systems. Background technique [0002] The suspension system is one of the main components in the vehicle chassis, which has an important impact on the ride comfort, driving maneuverability and passenger comfort of the vehicle during driving. Among the shock absorbers commonly used in vehicle suspensions on the market, barrel shock absorbers are mostly used. The piston assembly of this type of shock absorber has a piston compression check valve, a piston stretching check valve and a piston flow valve, and a bottom valve assembly has a bottom valve compression check valve, a bottom valve stretching check valve and a bottom valve. Through the circulation valve, the piston moves up and down during the compression and expansion proce...
