Abstract

The invention discloses an adjustable hydraulic shock absorber, which comprises a cylinder, an oil chamber is arranged in the cylinder, an air chamber is arranged between the oil chamber and the outer wall of the cylinder, and the bottom of the oil chamber communicates with the air chamber through a regulating valve. A piston rod is movably inserted into the oil chamber, and the end of the piston rod is fixed with a sealing plug that slides in contact with the inner wall of the oil chamber. An oil hole is opened on the sealing plug. The regulating valve includes a valve body, and a spool is movable in the valve body. , the spool is connected with the servo motor, the outer edge of the spool is provided with an airbag, the airbag is equipped with a spring, and the airbag is connected with the intake and exhaust pipes; the inner edge of the oil hole is connected with several baffles through torsion springs. The invention can improve the deficiencies of the prior art and reduce the interference to the damping action of the shock absorber during the adjustment process.

Description

Technical field [0001] The present invention relates to a shock absorber, in particular an adjustable hydraulic shock absorber. Background [0002] Shock absorbers are widely used in various devices such as vehicles that generate vibrations during operation to buffer vibrations. In recent years, adjustable shock absorbers have gradually become popular, and adjustable shock absorbers are adjusted to achieve changes in shock absorption effects through the adjustment of damping of shock absorbers. However, the existing adjustable shock absorber will cause interference in the shock absorption process during the adjustment process, resulting in a poor experience of the adjustable shock absorber. Contents of the Invention [0003] The technical problem to be solved by the present invention is to provide an adjustable hydraulic shock absorber, which can solve the shortcomings of the prior art and reduce the interference of the shock absorber vibration reduction during the adjustment pr...
