Abstract
The utility model relates to an inner ring locking wheel hub bearing, which comprises a flange plate (1), a gear ring (2), a wheel hub inner ring (7) which is connected on the flange plate, a sensor (6) connecting with the gear ring, an outer ring (8) connecting with the fringe of the inner ring, a rolling element (6) arranged between the flange plate (1) with the inner ring and the outer ring, a double channel symmetrically arranged inside the outer ring, a crown face which is adaptive to the rolling element and is arranged on the interface of the section of the double channel. The utility model is characterized in that: the inner ring (7) completely contacts the step faces (9) of the neck of the flange plate (1) and interference fit locks the step faces (9) of the neck of the flange plate (1).The replacement of the inner ring locking for the snap ring locking simplifies the processing of the step part of the flange plate; at the same time, as the steel material of the inner ring is better than the material of the snap ring, the strength of the product is improved, thereby, making the structure of the wheel hub bearing compact and reducing weight and size.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, especially relates to a kind of to the isostructural improvement of the tight hub-bearing unit of inner ring ring lock.
Background technology
Present hub-bearing unit is the parts in a kind of automobile suspension system, and it is general only as the supporting of automotive wheel, possesses the basic function of transfer torque.And the ABS system that is equipped with on the present automobile is meant the braking automobile antiblock device, is also referred to as anti-sideslip brake equipment, is made up of pulse wheel and inductance sensor, and it is the new and high technology device of automobile braking safety.How does that combine both?
Chinese patent discloses a kind of hub-bearing unit (publication number: CN2621123) with abs sensor, it is characterized in that on wheel hub, being provided with abs sensor, magnetic steel sleeve in the abs sensor is contained on the gear ring swivel, and matches with it, and the gear ring swivel is with flange captives joint.Though it combines the technology of hub-bearing unit and ABS system, solved certain technical matters, but need because cooperate, its flange neck step part processed complex, and utilize snap ring that the flange neck is locked, therefore the intensity of product is not high, and the structure of unit is not compact, and can not obtain best prefastening load.
As mentioned above, there is following deficiency in prior art: flange neck step part processed complex, and utilize snap ring to the locking of flange neck, and the intensity of product is not high, and the structure of hub-bearing unit is not compact, and can not obtain best prefastening load.
Summary of the invention
The utility model has solved the problem of the flange neck step part processed complex of prior art existence, the utility model has also solved and has utilized snap ring that the flange neck is locked, product strength is not high, the structure of unit is not compact, and can not obtain the problem of best prefastening load, a kind of flange step part manufacture simplification is provided, has saved snap ring, the hub-bearing unit that utilizes inner ring locking to make product strength inner ring locking preferably.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of hub-bearing unit of inner ring locking, comprise flange, gear ring, be connected with the wheel hub inner ring on the described flange, described gear ring is connected with sensor, the inner ring periphery is connected with the outer ring, be provided with rolling body between the flange of band inner ring and the outer ring, the inboard, outer ring is provided with the double channel of symmetry, the contact surface in its cross section has the arc surface suitable with rolling body, it is characterized in that described inner ring contacts fully with flange neck step surface, and and flange neck step surface interference fit locking.Ring cross-section is L shaped in described, described gear ring be arranged on L shaped in the bottom of ring cross-section and adaptive with it, described inner ring width greater than the flange neck adaptive with it, promptly the small end face of inner ring lengthening plays the effect of locking flange axle journal.Described rolling body can be steel ball, and the utility model is directly locked replacement with original snap ring locking mechanism by inner ring, has not only saved the snap ring parts, and simultaneously because the steel of inner ring are better than the material of snap ring, has increased the intensity of product; But also because the fit system of gear ring, inner ring and flange neck part, make the hub-bearing unit compact conformation, help to reduce the weight and the size of hub-bearing unit, and can obtain best prefastening load, improved the reliability of hub-bearing unit.
As preferably, described from inner ring to and the adaptive flange neck arc surface of rolling body a step is arranged, and flange neck lateral surface between the two is parallel with the main shaft lateral surface.Flange neck step part just is " Z " shape, and manufacture simplification has improved work efficiency, makes that block construction can be compact more.
The utility model is skillfully constructed, and replaces original snap ring locking by inner ring locking, makes the utility model have following beneficial effect compared with the prior art:
On the technology, it makes the step part manufacture simplification of flange neck; On the structure, not only saved the snap ring parts, and, increased the intensity of product simultaneously because the steel of inner ring are better than the material of snap ring; But also because the fit system of gear ring, inner ring and flange neck part, make the hub-bearing unit compact conformation, help to reduce the weight and the size of hub-bearing unit, and can obtain best prefastening load, improved the reliability of hub-bearing unit.
