Description
Technical field
The utility model relates to a kind of assembly of automobile absorber, the automobile absorber oil sealing of particularly a kind of improvement.
Background technique
Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump, the oil sealing of existing automobile absorber fits together with guide sleeve, easily relative sliding is there is between oil sealing and guide sleeve, under some limit service condition, limit surface conditions and under some limit weather conditions, the situation that oil gas leaks outside can be there is, thus affect the performance of automobile absorber, affect the working life of vibration damper.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides the automobile absorber oil sealing that a kind of sealability is improved preferably.
The utility model in order to the technological scheme solving its technical problem and adopt is: a kind of automobile absorber oil sealing of improvement, comprise an oil sealing urceolus, described oil sealing urceolus is embedded at the oil sealing body of vibration damper, the centre of oil sealing urceolus is provided with a center hole plugged for piston rod, described center hole upper end is provided with the first sealing lip, first sealing lip and piston rod are tightly fitted formation inflation inlet, described center hole lower end is provided with the second sealing lip, second sealing lip is equally tightly fitted piston rod and in wedge shape, described first sealing lip and the second sealing lip one-body molded, and the first sealing lip and the second sealing lip are fixed on oil sealing urceolus upper end by support block, described support block lower end surface coordinates with guide sleeve upper-end surface, the below of described support block is provided with an annular protrusion, above described guide sleeve, correspondence is provided with the annular groove mated with annular protrusion.
As further improvement of the utility model, the outside of the second sealing lip is provided with an annular slot, is embedded an O type spring in annular slot.
As further improvement of the utility model, the cross section of described annular protrusion is circular, square or triangle.
The beneficial effects of the utility model are: oil sealing main body lower end convex design of the present utility model and guide sleeve groove design, can make to be formed between oil sealing with guide sleeve the mode that a kind of pin links, thus make to closely cooperate between oil sealing and guide sleeve, avoid automobile under some limit service condition, limit surface conditions and under some limit weather conditions, the situation that oil gas leaks outside can be there is, thus the performance that ensure that vibration damper of entirety.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Indicate in figure: 1-oil sealing urceolus; 2-center hole; 3-first sealing lip; 4-piston rod; 5-inflation inlet; 6-second sealing lip; 7-O type spring; 8-support block; 9-annular protrusion.
Embodiment
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
Fig. 1 illustrates the automobile absorber oil sealing of a kind of improvement of the utility model, comprise an oil sealing urceolus 1, described oil sealing urceolus 1 is embedded at the oil sealing body of vibration damper, the centre of oil sealing urceolus 1 is provided with a center hole 2 plugged for piston rod 4, described center hole 2 upper end is provided with the first sealing lip 3, first sealing lip 3 is tightly fitted with piston rod 4 and is formed inflation inlet 5, described center hole 2 lower end is provided with the second sealing lip 6, second sealing lip 6 is equally tightly fitted piston rod 4 and in wedge shape, described first sealing lip 3 and the second sealing lip 6 one-body molded, and the first sealing lip 3 and the second sealing lip 6 are fixed on oil sealing urceolus 1 upper end by support block 8, described support block 8 lower end surface coordinates with guide sleeve upper-end surface, the below of described support block 8 is provided with an annular protrusion 9, above described guide sleeve, correspondence is provided with the annular groove mated with annular protrusion 9.The outside of the second sealing lip 6 is provided with an annular slot, is embedded an O type spring 7 in annular slot, and the cross section of described annular protrusion 9 is circular, square or triangle.
On the downside of this implementation column oil sealing support block 8, annular protrusion 9 is tightly fitted with the guide sleeve of lower end, when piston rod is had an effect and is slided, form bridging between annular protrusion 9 and guide sleeve to connect, can not make, between guide sleeve and oil sealing, relative sliding occurs, the sealability of internal gas can be ensured like this, the laminating degree that under extreme conditions can ensure rubber parts and piston rod of O type spring 7 simultaneously, thus ensure the sealing usability of vibration damper.
