Problems solved by technology

[0004] Shock absorbers with this structure are commonly used at present, but there is a fatal weakness, that is, the piston rod is prone to bending, resulting in oil leakage from the shock absorber; in more serious cases, the lower end of the piston rod (at the piston valve) will break, The piston valve fell off, causing the shock absorber to fail

Abstract

The invention relates to the technical field of automobile shock absorbers, and discloses an improved shock absorber. The improved shock absorber comprises a piston rod, an outer cylinder barrel, a piston cylinder, a piston valve and a bottom valve; the piston rod is coaxially arranged in the outer cylinder barrel and fixedly connected with the bottom of the outer cylinder barrel; the bottom valveis fixedly arranged at the upper end of the piston rod; the piston cylinder is a hollow rod body of which one end is provided with an opening; the piston valve is fixedly arranged on the inner wall at the opening of the piston cylinder; the piston cylinder sleeves the piston rod from the open end of the piston cylinder; the piston valve is slidably connected with the outer wall of the piston rodin a matched mode; the bottom valve is slidably connected with the inner wall of the piston cylinder in a matched mode; and the outer cylinder barrel is filled with oil liquid and gas, the upper end of the outer cylinder barrel and the piston cylinder are arranged in a sealed mode, and the piston cylinder drives the piston valve to move back and forth relative to the piston rod. Accordingly, the transverse force resistance effect of the shock absorber is improved, and the service life of the shock absorber is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile shock absorbers, in particular to an improved shock absorber. Background technique [0002] Such as figure 1 As shown, it is a view of the internal composition of a traditional shock absorber, which can be defined functionally as a shock absorber composed of a piston valve 101 (Piston v / v ass'y) and a bottom valve 102 (Body v / v ass'y) that generate damping force ), the outer cylinder 103 (Base Shell) and inner cylinder 104 (Tube) that store oil and gas (air), the piston rod 105 (Rod) that transmits the movement of the car body, and the oil seal 106 (Oil Seal) that prevents internal gas or oil leakage Seal), guide sleeve 107 (Rod Guide) and lug assembly 108 (EyeAss'y). When the vehicle is running, the bumps on the road are transmitted from the wheels to the shock absorber, and the fluid in the shock absorber converts the elastic energy of the coil spring into heat energy, which rationalizes th...
