Abstract
The utility model discloses a guider for a vehicle vibration damper. The guider for the vehicle vibration damper comprises an annular base and bushings which are slidingly matched with a piston rod of the vibration damper, wherein the bushings are arranged in a mounting hole in the annular base; an oil outlet groove is formed in the side wall of the annular base; annular beads along the inner wall are arranged on the bottom of the mounting hole of the annular base; gaps remain between the annular beads and a mounting hole bottom face as well as between the annular beads and the bushings; a plurality of oil passing holes which axially penetrate through the annular beads are uniformly formed in the annular beads; and a branched oil tank which is communicated with the oil outlet groove is arranged at the bottom of the mounting hole. By a design that the annular beads are arranged on the inner wall at the bottom of the mounting hole of the annular base, lubricant remained on the surface of the piston rod is uniformly distributed effectively, excessive lubricant enters the branched oil groove through the oil passing holes on the annular beads and finally enters the oil outlet groove, so that pressure of oil gland of the vibration damper is effectively reduced, service life of the vibration damper is prolonged, and working efficiency of the damper is improved.
Description
Technical field
The utility model relates to a kind of accessory of automobile absorber, is specially a kind of guide apparatus for automobile shock absorber.
Background technique
For accelerating the decay of vehicle frame and body vibrations, to improve ride of vehicle, in the suspension system inside of most of automobiles vibration damper is housed.Concussion when vibration damper is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.The working principle of vibration damper is when being subjected to vibration relative movement to occur between vehicle frame or wheel and the vehicle body, piston in the vibration damper moves up and down, pressure oil in the vibration damper just flows in the shock absorber oil storage cylinder through different throttle orifices from a vibration damper clutch release slave cylinder repeatedly, the at this moment friction between hole wall and the hydraulic oil and the intermolecular interior friction of hydraulic oil forms damping force to vibration, make automobile vibrational energy be converted into fluid heat energy, be dispersed in the atmosphere by the vibration damper absorption again.
Guider is one of important spare part in the vibration damper, and it has played good leading role to the motion of piston rod in the vibration damper, and has born the huge lateral force that produces therefrom, and the oilhole by guider is communicated with clutch release slave cylinder and oil storage cylinder simultaneously.Yet in actual use, because long-time the use, meeting more residual lubricant oil on piston rod surface, can cause like this oil sealing pressure of vibration damper to increase, make simultaneously the lubricant film on the piston rod surface inhomogeneous, thereby shorten the working life of vibration damper, affect the working efficiency of vibration damper.
The model utility content
The purpose of this utility model provides a kind of guide apparatus for automobile shock absorber, traditional guider can not carry out uniform treatment to the residual lubricant oil on the piston lever of reducer in the prior art to solve, and then lip-deep lubricant film is inhomogeneous when piston rod is used, and affects the vibration damper problem in working life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of guide apparatus for automobile shock absorber, the lining that includes annular base body and be slidingly matched with piston lever of reducer, described lining is installed in the mounting hole on the annular base body, described annular base body sidewall is provided with out oil groove, it is characterized in that: the mounting hole bottom of described annular base body is provided with circular fin along inwall, described circular fin leaves the gap respectively and between mounting hole bottom surface and the lining, evenly be provided with the oil-through hole that several axially connect circular fins on the described circular fin, described mounting hole bottom is provided with and the branch's oil groove that goes out oil groove and be communicated with.
Described a kind of guide apparatus for automobile shock absorber is characterized in that: described circular fin height diametrically is identical with the thickness of lining.
Described a kind of guide apparatus for automobile shock absorber is characterized in that: the bump surface of described circular fin is curved.
The beneficial effects of the utility model are:
The utility model adopts the design that circular fin is set in the mounting hole bottom interior wall of annular base body, lubricant oil residual on the piston rod surface is evenly distributed, and make unnecessary lubricant oil enter branch's oil groove by the oil-through hole on the circular fin, finally enter out oil groove, can effectively alleviate like this pressure of oil seal for shock damper, make simultaneously to form the uniform lubricant film of one deck on the piston rod, thereby prolonged the working life of vibration damper, promoted the working efficiency of vibration damper.
