Abstract

The invention discloses an adjustable hydraulic shock absorber. The adjustable hydraulic shock absorber comprises a cylinder body, wherein an oil cavity is formed in the cylinder body; an air chamberis formed between the oil cavity and the outer wall of the cylinder body; the bottom of the oil cavity communicates with the air chamber through an adjusting valve; a piston rod is movably inserted and connected into the oil cavity; and a sealing plug in sliding contact with the inner wall of the oil cavity is fixed to the tail end of the piston rod; an oil passing hole is formed in the sealing plug; the adjusting valve comprises a valve body; a valve element is movably arranged in the valve body, and is connected with a servo motor; an air bag is arranged on the edge of the outer side of thevalve element; a spring is arranged in the air bag; the air bag is connected with an air inlet and outlet pipe; and a plurality of baffle plates are connected to the edge of the inner side of the oilpassing hole through torsional springs. The adjustable hydraulic shock absorber has the advantages that the defects in the prior art can be overcome; and the interference on the shock absorption action of the shock absorber in the adjusting process is reduced.

Description

technical field [0001] The invention relates to a shock absorber, in particular to an adjustable hydraulic shock absorber. Background technique [0002] Shock absorbers are widely used in various equipment that generate vibration during operation, such as vehicles, to cushion the vibration. In recent years, adjustable shock absorbers have gradually become popular. Adjustable shock absorbers realize changes in the shock absorption effect by adjusting the damping of the shock absorber. However, the adjustment process of the existing adjustable shock absorber will interfere with the shock absorption process, resulting in poor user 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 deficiencies of the prior art and reduce the interference to the damping action of the shock absorber during the adjustment process. ...
