Abstract

The invention relates to the technical field of shock absorbers, and discloses a floating piston assembly and a shock absorber. The floating piston assembly comprises a floating piston and a sealing ring, wherein the floating piston is provided with an annular groove, the sealing ring is arranged in the annular groove in a sleeving mode, and a sealing space is formed by the sealing ring and the inner wall of the annular groove; a first skirt part is arranged at the upper end of the floating piston, a first via hole is formed in the first skirt part, and the first via hole communicates with thesealing space; and a second skirt part is arranged at the lower end of the floating piston, a second via hole is formed in the second skirt part, and the second via hole communicates with the sealingspace. The shock absorber comprises a cylinder body and the floating piston assembly, and the floating piston assembly is installed in the cylinder body. According to the floating piston assembly, the first via hole and the second via hole which communicate with the annular groove are formed in the floating piston, pressure on the inner side and the outer side of the sealing ring is balanced, deformation of the sealing ring is uniform, and the sealing effect is good. The shock absorber adopts the floating piston assembly, so that the shock absorbing and buffering performance is better.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a floating piston assembly and a shock absorber. Background technique [0002] The shock absorber is a component used to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the car. The single-tube gas-filled shock absorber is a commonly used type of shock absorber. The cylinder of the single-tube gas-filled shock absorber is equipped with a working piston and a floating piston. The working piston is on the top and the floating piston is on the bottom. The cylinder is divided into two parts: Three parts, the closed space on the upper and lower sides of the working piston is filled with high-pressure liquid, the working piston is provided with a damping hole, and a closed air chamber is formed between the lower part of the floating piston and the cylinder body. The floating piston separates the liquid and gas on both sides ...
