Description
Technical field
The present invention relates to a kind of vehicle shock absorber more particularly to a kind of reciprocating vehicle dampings equipped with sealing buffering ring
Device belongs to damper technical field.
Background technique
Damper is component important on vehicle, is directly related to the comfort of vehicle ride.It is accurate easy as one
Part is damaged, the grade of damper cleaning inside degree directly influences the service life of damper.Damper is by various metals and non-
Metal parts assembling is welded, in the process of damper components, there are cleannes phenomenons not up to standard,
The impurity such as welding slag can be generated when welding each part on production line again.If being mixed into these impurity when damper finally assembles, just
It is not up to standard cleannes to be led to the problem of.Meanwhile in the use process of damper, because abrasion and vibration, can also generate miscellaneous
Matter.The impurity generated in the impurity and damper use process brought into components assembling process can all destroy the sealing of damper
System shortens the service life of damper, and studying carefully its essence is that impurity passes through and be embedded in guider inner wall inside damper, scratches and lives
Stopper rod and then the lip for destroying damper upper end oil sealing, cause damper oil leak.
Currently, the application technology for the reciprocating damper not being mounted on domestic market on automobile, existing past
In compound damper, as shown in Figure 1, guider lower end is not provided with sealing buffering ring.
In face of problems, although damper producer is controlling always cleannes grade, can not avoid completely, and
And all components cleannes of control spent it is expensive.
Summary of the invention
The present invention, in deficiency present on automobile, provides a kind of reciprocal for the reciprocating shock absorber application on existing market
Formula vehicle shock absorber sealing device.
The technical solution that the present invention solves above-mentioned technical problem is as follows：
A kind of reciprocating vehicle shock absorber sealing device is led including surrounding the guider 1 of 4 periphery of piston rod and being installed on
To the oil sealing 2 above device, the lower section of the guider is equipped with sealing buffering ring 5, and the sealing buffering ring is by the first support frame 6
It is formed with integrally formed the first rubber bodies 7 being located on the outside of the first support frame of the first support frame, the sealing buffering
The outer diameter position of ring and the pilot hole of guider are interference fitted to form static seal structure, and the inside of first rubber bodies is equipped with extremely
Few auxiliary sealing lip 8 together.
Further, the oil sealing is integrally formed by the second support frame 12 and with the second support frame positioned at the second support rib
The second rubber bodies 13 composition on the outside of frame, the inside of second rubber bodies are equipped at least one of primary seal lip 3, second rubber
The outside of colloid is equipped with upper and lower two holdings spring 14.
Further, the section of auxiliary sealing lip is triangular in shape.
The beneficial effect of vehicle shock absorber of the invention sealing device is：
1) the neck bush position that the auxiliary sealing lip of buffering ring can stop the impurity inside damper to enter guider is sealed
With the primary seal lip position of oil sealing, avoids the damper oil leak that piston rod surface scratches and the scuffing of primary seal lip is caused and lose
Effect, to improve the product quality of oil sealing and vibration damper assembly；
2) presence for sealing buffering ring can reduce impact of the damper internal high pressure oil liquid to oil sealing primary seal lip.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the lower end surface of first rubber bodies is equipped with several circumferentially extending grooves 11.
Beneficial effect using above-mentioned further technical solution is damper can be prevented when there is overrun state, limit
The upper surface of position block 9 is in contact with the lower end surface of sealing buffering ring, to play the role of bumper and absorbing shock.
Further, the ripple glaze 10 independent being equipped with along the vertical direction on the inside and outside side of first rubber bodies.
Beneficial effect using above-mentioned further technical solution is that damper is enabled to play better bumper and absorbing shock
Effect.
Further, first support frame is L-shaped, and the outside of first support frame is exposed while inside is by
One rubber bodies are coated, and are interference fitted to form static seal with the pilot hole with guider on the outside of the long side of first support frame
Structure.
