The invention relates to an automobile shock absorber with a sealing ring type two-way valve. The automobile shock absorber with the sealing ring type two-way valve comprises a cylinder barrel. An inner cavity is formed in the cylinder barrel, and one end of the inner cavity is open. An installation ring is arranged at the other end of the cylinder barrel. A piston rod is installed in the inner cavity, a lower plug assembly is installed at the bottom of the inner cavity, and an upper plug assembly is installed on the joint of the piston rod and the cylinder barrel. A piston assembly which is linked with the piston rod is installed on the end portion of the end, stretching into the inner cavity, of the piston rod. A floater assembly which can move along the inner cavity is installed in theinner cavity. An air cavity is formed between the floater assembly and a lower plug, and an inflation valve is installed in the air cavity. A second oil cavity is formed between the piston assembly and the floater assembly, a first oil cavity is formed between the upper plug assembly and the piston assembly, and the first oil cavity and the second oil cavity are filled with shock absorption oil. The sealing ring type two-way valve structure is arranged in the piston assembly and comprises a first oil passing valve structure and a second oil passing valve structure.
Description
technical field [0001] The invention relates to the field of automobile shock absorbers, in particular to an automobile shock absorber with a sealing ring type two-way valve. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, the suspension system of the car is generally equipped with a shock absorber. The two-way acting barrel shock absorber is widely used in the car. The type automobile shock absorber has high heat generation, high noise, heavy weight, and short service life, which cannot well meet the needs of automobiles for the use of shock absorbers. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art, [0004] Provide a kind of automobile shock absorber with sealing ring type two-way valve with simple structure, few parts, light weight, low heat generation, lo...
