Automobile damping guider with air seal structure

Abstract

The invention discloses an automobile damping guider with an air seal structure. According to the automobile damping guider with the air seal structure, the outer wall of a second pipe body is sleevedwith a sealing leather sleeve, and the sealing leather sleeve is arranged at an output of an oil outlet hole in an attachment plugging manner; the sealing leather sleeve is used to control the oil outlet hole to be opened or closed; the outer wall of a first pipe body is sleeved with an oil guide ring, oil guide grooves are formed in the edge of the oil guide ring, and the oil guide grooves are used to discharge high-pressure oil; the oil guide grooves are disturbed on the outer side of the sealing leather sleeve in a staggered manner, and the end face of the end, close to the first pipe body, of the sealing leather sleeve is an openable end face; and the openable end face is attached to the side wall of the oil guide ring, and the oil guide ring is used to prevent high-pressure gas fromflushing the openable end face open. According to the automobile damping guider with an air seal structure, the sealing leather sleeve is used to control the oil outlet hole to be opened or closed; itis achieved that when the oil pressure in a third pipe body is over high, the sealing leather sleeve is opened to release oil fluid, and when the oil pressure in the third pipe body is relatively low, the sealing leather sleeve keeps the closed state; and therefore, it is avoided that the gas in a storage chamber enters an air cylinder pipe through the oil outlet hole.

Description

technical field [0001] The invention belongs to the technical field of shock absorber production, in particular to an automobile shock absorber guide with an air seal structure. Background technique [0002] The shock absorber is composed of a piston valve and a bottom valve that generate damping force, a cylinder body and a storage pipe that store oil and gas (air), a connecting rod that transmits the movement of the car body, and an oil seal that prevents internal gas or oil leakage; The valve is used as a reference, the upper part is called the piston joint upper chamber, the lower part is called the piston lower chamber, the storage pipe and the cylinder; the space between the body is called the storage chamber; the piston upper chamber is always filled with oil, and the lower layer of the storage chamber Filled with oil, the upper layer is filled with air or gas (nitrogen); [0003] A guide is installed on the inner top of the storage chamber, and the oil piston rod ru...

AI Technical Summary

Problems solved by technology

[0004] Current directors such as Figure 7 As shown, the outside of the guide lacks a sealing structure. When the oil pressure in the guide is low and there is no need for oil discharge and pressure relief, the gas in the upper layer of the storage room can be poured into the guide through the oil outlet hole, and the storage room is filled with air. It will affect the stability of the oil movement, destroy the dynamic balance of the oil pressure in the storage room, pose a safety hazard, and affect the shock absorption effect
