Abstract
The present invention relates to a kind of amortisseur sealing device, including shock structure and be sheathed on the urceolus outside shock structure, it is provided with Oil sealing assembly between described shock structure and urceolus, it is characterized in that, main lip one end of described Oil sealing assembly is provided with internal dust preventing component, the lower section of described Oil sealing assembly is provided with jump ring, is provided with outside dust preventing component between bottom and the shock structure of described urceolus.On the one hand the sealing device that the present invention provides can stop that the internal impurity of amortisseur arrives oil sealing main lip position, thus avoids oil seal lip to scratch and amortisseur leakage of oil；Two can reduce the shock absorber fluid impact to oil seal lip, improve the service life of amortisseur.
Description
Technical field
The present invention relates to a kind of amortisseur, particularly relate to the inversion amortisseur of a kind of automobile, motorcycle, belong to amortisseur close
Encapsulation technique field.
Background technology
Reciprocating hydraulic structure is parts conventional in modern vehicle, engineering machinery, the especially application of amortisseur,
Widely, (one is the impurity that the front parts of assembling are brought into, and two is to subtract all to have certain impurity inside existing amortisseur
The impurity that during shake device use, inter deterioration produces), particularly with being inverted amortisseur, in use, internal impurity exists
Under gravity and reciprocating effect, pass through from the gap between shock structure and neck bush (or urceolus), and be deposited in oil sealing master
Lip region, and under reciprocating motion effect, gradually run up to inside oil sealing, main for oil sealing lip is paved, causes scratching oil sealing
Lip and leakage of oil.From the point of view of the feedback analysis in market, dominant failure mode is the entrance oil seal lip such as dust and silt thus makes
Becoming and scratch leakage of oil, at present in addition to stopping external dust and silt and entering amortisseur inside, the internal impurity of its amortisseur enters oil
Envelope lip causes scuffing leakage of oil, is also particularly important, becomes apparent from particularly with being inverted amortisseur performance.
Summary of the invention
The problem that the present invention is directed to scratch leakage of oil present in existing amortisseur use process, it is provided that a kind of amortisseur seals
Device.
The technical scheme is that
A kind of amortisseur sealing device, including shock structure be sheathed on the urceolus outside shock structure, described shock structure and outer
Oil sealing assembly it is provided with, it is characterised in that main lip one end of described Oil sealing assembly is provided with internal dust preventing component, described oil between Tong
The lower section of sealing assembly is provided with jump ring, is provided with outside dust preventing component between bottom and the shock structure of described urceolus.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described internal dust preventing component is made up of support frame and elastic sealed body.
Further, the one during described elastic sealed body is dust seal, O, rectangular loop.
Further, described elastic sealed body is made up of the one in rubber, PTFE, polyurethane.
Further, described internal dust preventing component be also arranged above pad, being arranged over of described pad is sheathed on damping
Neck bush between post and urceolus.
The invention has the beneficial effects as follows:
On the one hand the sealing device that the present invention provides can stop that the internal impurity of amortisseur arrives oil sealing main lip position, from
And avoid oil seal lip to scratch and amortisseur leakage of oil；Two can reduce the shock absorber fluid impact to oil seal lip, improve amortisseur
Service life.
