Abstract

The invention discloses a cylindrical oil leakage preventing shock absorber. The shock absorber comprises a plunger rod, a working oil cylinder, an oil seal and a protective cover, wherein the outer side of the shock absorber is coated with the protective cover; the upper end of the plunger rod is fixed on the shock absorber, and the lower end of the plunger rod is fixed on a circulating valve and a rebound valve for dividing the working oil cylinder into an upper working oil cylinder and a lower working oil cylinder; the top of the upper working oil cylinder is sealed by the oil seal; the bottom of the lower working oil cylinder is fixed on a compression valve and a supply valve; an oil storage barrel is arranged at the outer side of the working oil cylinder; a through port is formed in the oil seal, and is connected with an oil collecting barrel; and the circulating valve, the rebound valve, the compression valve and the supply valve are respectively coated with lantern rings. The cylindrical oil leakage preventing shock absorber has the following beneficial effects: the oil collecting cylinder connected to the outer side of the working oil cylinder effectively relieves the oil leakage caused by uneven pressure generated in the movement of the plunger rod; the added lantern rings can prevent the oil leakage phenomenon of the circulating valve, the rebound valve, the compression valve and the supply valve; and the oil seal adopts a sealing rubber synthesized by acrylic ester to improve the tightness.

Description

A kind of cartridge type anti-oil leakage damper
Technical field
The present invention relates to technical field of automobile parts, particularly relate to a kind of cartridge type anti-oil leakage damper.
Background technique
Along with economic level, the improving constantly of living standard, the car population of China is also improving constantly.Vibration damper as a kind of component of car, concussion when rebounding after being mainly used for suppressing spring shock-absorbing and the impact from road surface.But presently, vibration damper, once leakage of oil, just must be changed, and loses time and sinks money, therefore, a kind of new technological scheme is needed to solve the problem.
Summary of the invention
The invention provides a kind of cartridge type anti-oil leakage damper.
The technical solution used in the present invention: a kind of cartridge type anti-oil leakage damper comprises plunger rod, working oil cylinder, oil sealing and protective housing, shielding cover is in the outside of vibration damper, the upper end of plunger rod is fixed on vibration damper, the lower end of plunger rod fixes flowing valve and working oil cylinder is divided into upper working oil cylinder and lower working oil cylinder by rebound valve, the top oil sealing sealing of upper working oil cylinder, compression valve and replenish valve are fixed in the bottom of lower working oil cylinder, oil-storing barrel is provided with outside working oil cylinder, oil sealing is provided with port, port connects oil collection barrel, flowing valve, rebound valve, on compression valve and replenish valve, all cover has the collar.
The material of protective housing is ethylene propylene diene rubber, and the material of the collar is the nitrile butadiene rubber of sulfuration, wraps up one deck acrylate synthetic rubber outside oil sealing.
Beneficial effect of the present invention: the oil pooling cylinder of the outside connection of working oil cylinder, the leakage of oil that the pressure inequality occurred when effectively alleviating plunger rod activity causes; The collar increased can prevent the oil leakage phenomenon of flowing valve, rebound valve, compression valve and replenish valve from occurring; Oil sealing adopts the caulking gum of acrylate synthesis to add sealing.
