Embodiment Construction

[0010] Further illustrate the present invention below in conjunction with accompanying drawing.

[0011] Such as figure 1 The present invention discloses a gas-filled shock absorber, including a closed air chamber 1, a floating piston 2, an O-ring 3, a compression valve 4, a working cylinder 5, a piston rod 6, a working piston 7, and an extension valve 8 , the bottom of the working cylinder is equipped with a floating piston, the floating piston and one end of the working cylinder form a closed air chamber 1, the piston rod 6 is perpendicular to the floating piston, and the O-ring 3 is installed on the floating piston, so The working piston 7 is above the O-ring 3, and the compression valve 4 and the expansion valve 8 are mounted on the working piston 7.

[0012] When the wheel jumps up and down, the working piston of the shock absorber reciprocates in the oil, so that there is an oil pressure difference between the upper chamber and the lower chamber of the working piston, a...

Abstract

The invention discloses an inflatable vibration damper, which is characterized by including a sealed air chamber, a floating piston, an O-shaped seal ring, a compression valve, a working cylinder, a piston rod, a working piston and a rebound valve, wherein the floating piston is mounted at the lower part of the working cylinder and connected with one end of the working cylinder into the sealed air chamber; the piston rod is vertical to the floating piston; the O-shaped seal ring is mounted on the floating piston; the working piston is arranged above the O-shaped seal ring; and the compression valve and the rebound valve are mounted on the working piston. The structure of the inflatable vibration damper is simplified by adopting the floating piston, and meanwhile the O-shaped seal ring with a big cross section on the floating piston separates the high-pressure gas from the oil gas, thereby avoiding the oil emulsification.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a gas-filled shock absorber. Background technique [0002] In order to speed up the attenuation of the frame and body and improve the ride comfort of the car, shock absorbers are installed inside the suspension system of most cars. At present, two-way acting barrel shock absorbers are widely used in automobiles, but the structure of the two-way acting barrel shock absorbers is complex and prone to oil emulsification. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a gas-filled shock absorber in order to solve the deficiencies of the prior art. [0004] Technical solution: In order to achieve the above objectives, a gas-filled shock absorber according to the present invention is characterized in that it includes a closed air chamber, a floating piston, an O-ring, a compression valve, a working cylinder, a piston rod, and a working pisto...
