Problems solved by technology

[0003] When the hydraulic medium inside the existing barrel shock absorber is under pressure and flows, it does not have a good effect of blocking the flow of the hydraulic medium, so that the shock absorber needs to increase its own expansion and contraction range to buffer the vibration, and the shock absorption effect is not good. good

Abstract

The invention relates to the technical field of vehicle shock absorbers and discloses a cylindrical shock absorber for an automobile suspension in order to solve the problem that when a hydraulic medium in an existing cylindrical shock absorber flows due to pressure, the flow choking effect on the hydraulic medium is not good, and the cylindrical shock absorber for the automobile suspension comprises a cylinder filled with the hydraulic medium. A first piston mechanism and a second piston mechanism are arranged at the two ends of the cylinder correspondingly and used for buffering and damping the two adjacent suspensions. A first piston and a second piston move in the barrel and drive the hydraulic medium to flow into or out of a shell through penetrating holes in a reciprocating mode, at the moment, an arc-shaped component buffers and blocks the hydraulic medium flowing into the shell, and the contact area between the arc-shaped component and the hydraulic medium is increased through the arc-shaped component of the arc-shaped structure; and meanwhile, when the hydraulic medium in the shell flows back into the cylinder, the outer arc surface of the arc-shaped part blocks the flow of the hydraulic medium, a first elastic part slows down the movement of the arc-shaped part, the flowing of the hydraulic medium in the barrel is effectively slowed down, and the buffering and damping effects are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle shock absorbers, in particular to a barrel-type shock absorber for vehicle suspension. Background technique [0002] In order to quickly attenuate the vibration of the frame and the body in the car, a shock absorber is generally installed between two adjacent suspensions in the suspension system, and the shock absorber absorbs the vibration of the suspension to improve the ride comfort and stability of the car. Comfort, among which the barrel shock absorber is a commonly used shock absorber structure. [0003] When the hydraulic medium inside the existing barrel shock absorber is under pressure and flows, it does not have a good effect of blocking the flow of the hydraulic medium, so that the shock absorber needs to increase its own expansion and contraction range to buffer the vibration, and the shock absorption effect is not good. good. Contents of the invention [0004] The purpose of the p...
