The utility model provides a wheel hub bearing unit closes wheel hub bearing and ball cage as an organic whole, compact structure, simple to operate is simple.
Description
Technical field
The utility model relates to a kind of automobile component, particularly a kind of hub-bearing unit.
Background technology
Hub bearing plays transfer torque and the effect of supporting car body as important parts of automobile.Existing hub-bearing unit earlier with the hub-bearing unit entrucking, penetrates the ball cage central bore of hub bearing unit afterwards when entrucking, and uses hub nut that hub-bearing unit and ball cage lock are one.But annex is more during the entrucking of this kind structure, and the degree of modularity is not high, and entrucking is inconvenient; And locking torque will exert an influence to the installation play of product in the process of entrucking jam nut, is not easy to control, influences the practical life of product.
The utility model content
The purpose of the utility model provides a kind of hub-bearing unit, and its simple in structure, easy for installation, reliability and durability has solved the problems referred to above well.
A kind of hub-bearing unit; Comprise outward flange dish and inner flange; Said inner flange rigid fit has half inner ring, and it also comprises a ball cage, and said ball cage has a pipe link; Said pipe link passes inner flange and spline connection with it, and the free end that said pipe link passes inner flange is provided with flange.
Preferred as the utility model; Ball receway under in the outside of said inner flange is provided with; The outside of said half inner ring is provided with outer ball receway down, said outward flange dish inboard be respectively equipped with said in the interior outer upward ball receway of going up ball receway and cooperating that cooperates of ball receway down with said outer ball receway down; Go up in said ball receway with interior down between the ball receway, said outer go up ball receway with said outside under all be provided with retainer between the ball receway, be provided with rolling body in the said retainer.The above-mentioned rotation that is set to wheel hub provides accurate guiding.
Preferred as the utility model, said inner flange is equipped with the ABS gear ring near an end of half inner ring, and said outward flange dish is provided with sensor near an end of half inner ring.
Preferred as the utility model, said inner flange also is provided with positioning groove near an end of half inner ring, is provided with in the said positioning groove and the fastening block of half inner ring, one side.
Preferred as the utility model, said outward flange dish is away from being provided with seal ring between end of half inner ring and the inner flange, and said seal ring is a mulit-lip seal ring; Said seal ring is outside equipped with the cover of dust I; Be provided with the cover of dust II between said sensor and the inner flange.Being provided with of seal ring and cover of dust can be played dustproof and leak free effect.
Further preferred as the utility model, dress is pressed with boss bolt on the said outward flange dish, and hub-bearing unit can directly be connected with the automobile miscellaneous part.
In sum, the utlity model has following advantage:
Ball cage pipe link passes inner flange and spline connection with it; And be provided with flange and inner flange is fastening at the free end of pipe link; This structure is integrated hub-bearing unit and ball cage; Play transfer torque effect better, in the entrucking process, need the ball cage be locked on the inner flange, can not produce the play influence in the installation process.The hub-bearing unit compact conformation that the utility model provides, easy for installation simple, assembling trap rate is high.
