Description
Technical field
The present invention relates to a kind of bearing, more particularly, to a kind of vehicle shock absorber bearing.
Background technology
Vibration is produced because flexible member is hit in automobile suspension system, is to improve vehicle running smoothness, suspension
In be installed in parallel shock absorber with flexible member, be decay vibration, wherein shock absorber be mainly used to suppress spring shock-absorbing after
Concussion during bounce-back and the impact from road surface.When by uneven road surface, although shock-absorbing spring can filter road surface
Vibrations, but spring itself also has reciprocating motion, and shock absorber for suppressing the jump of this spring.
From shock absorber operation principle, the requirement of shock absorber bearing working, be mainly hit load, and rotation mode is
Without spin and low speed oscillations, and it is chronically at dust and diffuses, is worked in the adverse circumstances that mud splashes, thus it is right
Its reliability requirement is high.Current domestic manufacturer production standard thrust ball bearing, using effect is undesirable, main table
Now：The phenomenons such as rotation is dumb, grease leakage throws away, raceway early stage peeling, product corrosion cause bearing in early days
Fail, therefore host computer market is mainly still monopolized with the class bearing by external producer.
The content of the invention
The purpose of the present invention is exactly to provide one kind and improve bearing for the defect for overcoming above-mentioned prior art to exist
Life-span, the vehicle shock absorber bearing of install convenient.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of vehicle shock absorber bearing, it is characterised in that described including seat ring, blowout patche, steel ball and case
Seat ring, steel ball and blowout patche are set gradually, and the raceway groove of steel ball rolling is respectively provided with described seat ring and blowout patche,
Described seat ring and blowout patche is wrapped up by case.
Raceway groove on described seat ring and blowout patche is unsymmetric structure, and its ditch outside is higher than ditch inner side.
Described case includes outer casing and inner can, and described inner can is connected after encasing seat ring with blowout patche, makes axle
Circle is fixedly connected with seat ring, and described outside housing cover encases blowout patche.
Described inner cover lid is U-shape structure, and two perpendicular ends bend inwards, with being brought into close contact for blowout patche.
Described outer casing is inverted U-shaped structure, and it is connected with blowout patche interference fit.
Described case is the case after phosphorating treatment.
The Bearing inner is full of lubricating grease.
Described lubricating grease is Volkdwagen RENOLITFCH2 lubricating grease
The radius of curvature of described raceway groove is 0.52.
Compared with prior art, the present invention has advantages below：
1st, when bearing produces swing, steel ball can produce a centrifugal force laterally, and the centrifugal force belongs to radially
Power, can be supported by raceway groove outside rib higher, it is ensured that it is oval all inside raceway groove that contact stress is produced,
So as to improve the life-span of bearing.
It is mainly low speed oscillations and shock loading when the 2, being worked due to the product, raceway groove is set using smaller ditch curvature
Meter, raceway groove increases with rolling element contact area, and bearing capacity is improved, and the life-span is significantly lifted.
3rd, inner can encases seat ring and blowout patche, grease work when be difficult to throw away, and outside dust, mud
Bearing inner cannot be penetrated into, sealing function is played；The other case ensure that blowout patche and seat ring are not separated, and install just
It is prompt.
4th, all wrapped up using phosphatization case up and down, serving prevents product corrosion.
5th, grease uses Volkdwagen RENOLITFCH2 lubricating grease, and adhesive force is strong, and crush resistance is strong, low speed
Still ensure that rolling friction surface forms oil film covering under swing impact loading.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out it is clear,
It is fully described by, it is clear that described embodiment is a part of embodiment of the invention, rather than whole embodiments.
Based on the embodiment in the present invention, those of ordinary skill in the art are obtained on the premise of creative work is not made
The every other embodiment for obtaining, should all belong to the scope of protection of the invention.
As shown in figure 1, a kind of vehicle shock absorber bearing, including seat ring 1, blowout patche 2, steel ball 3 and case,
Described seat ring 1, steel ball 3 and blowout patche 2 set gradually, and are respectively provided with described seat ring 1 and blowout patche 2
The raceway groove of steel ball rolling, described seat ring 1 and blowout patche 2 is wrapped up by case.
Raceway groove on described seat ring 1 and blowout patche 2 is unsymmetric structure, and its ditch outside is higher than ditch inner side.
Described case includes outer casing 4 and inner can 5, and described inner can 4 is connected after encasing seat ring with blowout patche,
Blowout patche is set to be fixedly connected with seat ring, described outside housing cover encases blowout patche.Described inner cover lid 4 is U-shape structure,
Two perpendicular ends bend inwards, with being brought into close contact for blowout patche.Described outer casing 5 is inverted U-shaped structure, itself and axle
Circle interference fit connection.
The present invention carries out asymmetric design, i.e. ditch on the basis of common thrust ball bearing to its blowout patche and seat ring raceway groove
Outside can be supported higher than ditch inner side, the centrifugal force produced when steel ball rotates by outside rib higher, it is ensured that connect
Tactile stress is all in raceway groove.
Milling radius are designed as 0.52, it is ensured that steel ball is greater area of with channel surface to be contacted.
Blowout patche and seat ring are encased using inner can, it is ensured that blowout patche and seat ring can not be separated, and seat ring is individually using outer
Case is covered, it is ensured that whole bearing is exposed outside without any position；Envelope surface uses phosphorating treatment, to reach
Prevent the purpose of corrosion.The Bearing inner is full of lubricating grease.Lubricating grease uses Volkdwagen RENOLITFCH2
Lubricating grease.
When automobile turns round, tire swings to left or right, and shock absorber bearing swings therewith accordingly, the steel in bearing
Ball produces a centrifugal force, and the centrifugal force can cause steel ball to touch trench edges, of the invention high by raceway groove outside
In inner side design, it is ensured that the ellipse that contact stress is produced is all in raceway groove.When automobile bumpiness produces vibration, pass through
Shock absorber is decayed, and it vibrates, and the vibration produces impulsive force to bearing, easily causes local stress increase, channel surface
Produce depression.Smaller ditch curvature design, raceway groove is used to increase with rolling element contact area by its raceway groove, phase
Significantly reduce with the lower contact stress of load effect.Seat ring and blowout patche are encased by lower encioser, when grease works not
Easily throw away, and the dust of outside, mud cannot penetrate into Bearing inner, play sealing function；The other case is true
Blowout patche is protected and seat ring has not been separated, install convenient.By all being wrapped up using phosphatization case up and down, serve
Prevent product corrosion.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, can readily occur in various equivalent
Modification or replacement, these modification or replacement should all be included within the scope of the present invention.Therefore, the present invention
Protection domain should be defined by scope of the claims.
