Abstract
The invention discloses an anti-abrasion piston guider assembly device, and relates to a shock absorber of an automobile, in particular to an inner guider assembly device of the shock absorber. The anti-abrasion piston guider assembly device comprises a liquid storage cylinder, a work cylinder, a piston and a piston rod, wherein a rebuilt valve is arranged on the piston, a compensation valve is arranged at the bottom of the work cylinder, an abrasion reduction sleeve is arranged at the upper end of the work cylinder, a guider is arranged at the upper portion of the abrasion reduction sleeve, an oil seal is arranged between the liquid storage cylinder at the upper end of the guider and the piston rod, and a sealing ring is arranged between the guider and the abrasion reduction sleeve. The anti-abrasion piston guider assembly device has the advantages that after the technical scheme is adopted, an oil storage cup is formed between the guider and the oil seal, the piston rod and a lip port of the oil seal are always located in lubricating oil, and the abrasion of the piston rod, the abrasion reduction sleeve and the guider is reduced. Meanwhile, a sealing function is achieved for the piston rod, and the service life of the shock absorber is prolonged.
Description
Technical field
The present invention relates to a kind of motor vehicle damper, refer more particularly to guider assembly device in a kind of vibration damper.
Background technique
Concussion when vibration damper is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.The cylinder sleeve of vibration damper and piston are to work under high temperature, high pressure and high load conditions, and the high-speed friction due to piston rod and anti-attrition cover, guider, consequently must cause anti-attrition cover, guider abrasion deformation.Simultaneously, due to the friction of piston rod, the contacting part of piston rod and liquid storage cylinder is leaked, affect its working life.
Summary of the invention
The present invention is just in order to address the above problem, and a kind of Durable piston guider assembly device is provided, and it can effectively solve the wearing and tearing of anti-attrition cover, guider, has extended the working life of vibration damper.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of Durable piston guider assembly device, comprise liquid storage cylinder, clutch release slave cylinder, piston, piston rod, wherein piston is provided with rebuilt valve, the clutch release slave cylinder bottom is provided with recuperation valve, it is characterized in that, in the clutch release slave cylinder upper end, be provided with the anti-attrition cover, anti-attrition cover top is provided with guider, between the liquid storage cylinder of guider upper end and piston rod, is provided with oil sealing.
Between the above guider and anti-attrition cover, be provided with seal ring.
Advantage of the present invention is, after adopting technical solution of the present invention, makes between guider and oil sealing to have become an oil-storing cup, and piston rod and oil seal lip are among lubricant oil forever, have reduced the wearing and tearing of piston rod and anti-attrition cover, guider.Simultaneously, piston rod has been played to seal action, improved the working life of vibration damper.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1. liquid storage cylinder; 2. clutch release slave cylinder; 3. piston; 4. piston rod; 5. rebuilt valve; 6. recuperation valve; 7. guider; 8. anti-attrition cover; 9. seal ring; 10. oil sealing.
Embodiment
As can be known by accompanying drawing 1, liquid storage cylinder 1 of the present invention, clutch release slave cylinder 2, piston 3, piston rod 4, wherein piston 3 is provided with rebuilt valve 5, clutch release slave cylinder 2 bottoms are provided with recuperation valve 6, in clutch release slave cylinder 2 upper ends, be provided with anti-attrition cover 8, anti-attrition cover 8 tops are provided with guider 7, between the liquid storage cylinder 1 of guider 7 upper ends and piston rod 4, are provided with oil sealing 10.Between described guider 7 and anti-attrition cover 8, be provided with seal ring 9.
It should be noted that mode of execution of the present invention is only its optimal way, is only apparent change to belonging to technical solution of the present invention, within all should belonging to protection scope of the present invention.
