Abstract
The utility model relates to a nondriving wheel hub bearing with a turned edge structure, which comprises a flange plate (1), a hub inner ring (3) which is connected on the steps of the neck of the flange plate, a hub outer ring (4) which is connected with the fringe of the inner ring, a rolling elemen (5) arranged between the outer ring and the inner ring and neck of the flange plate, 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: a turned edge structure (6) is arranged at the top end of the neck of the flange plate (1); the turned edge structure (6) folds into the end face of the inner ring (3) with the adaption to the turned edge structure, tightening the inner ring (3) and flange plate (1) into a whole; the diameter of the turned edge is less than that of the end face of the inner ring. The utility model has the advantages of compact structure, high reliability, no axial slide and so on; moreover, the best preload can be obtained and the reliability of the wheel Hub Bearing can be improved.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, is a kind of improvement of structure of the non-driving wheel hub-bearing unit to roll coil of strip limit structure specifically.
Background technology
At present, automobile hub bearing generally includes flange, sheathed inner ring on the flange, inner ring peripheral hardware outer ring, be provided with steel ball, retainer and seal ring between outer ring and inner ring, the general inner circle of the axial restraint of inner ring is pressed into the flange neck and is mated, and fixes by jam nut, or the baffle ring in the inner ring outside be stuck in cooperate in the groove that the flange neck is provided with fixing.It is bigger that above-mentioned these structures exist the hub-bearing unit assembly structure, and the axial restraint of inner ring is unreliable, and inner ring is easy to generate problem such as endwisely slip.
As mentioned above, there is following deficiency in prior art: the hub-bearing unit assembly structure is bigger, and the axial restraint of inner ring is unreliable, and inner ring is easy to generate and endwisely slips.
Summary of the invention
The hub-bearing unit assembly structure that the utility model has solved the prior art existence is bigger, the axial restraint of inner ring is unreliable, and inner ring is easy to generate problem in axial sliding, a kind of compact conformation, good reliability is provided and has been difficult for producing non-driving wheel hub-bearing unit in axial sliding.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: the non-driving wheel hub-bearing unit of a kind of roll coil of strip limit structure, comprise flange, be connected with the wheel hub inner ring on the step of flange neck, the inner ring periphery is connected with the wheel hub outer ring, be provided with rolling body between inner ring and flange neck step place 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 flange neck end place is provided with bead structure, described bead structure is toward the inner ring large end face turnover adaptive with it, inner ring and flange are tightened to one, and the diameter of crimping is less than the diameter of inner ring large end face.The utility model is owing to be designed to bead structure near the flange neck end place outside the inner ring large end face, and there is the slotted hole of certain depth the crimping inboard, the diameter of crimping is less than the diameter of the inner ring large end face suitable with it, make the neck end place of flange produce plastic deformation, inner ring and flange are connected to one, make whole hub-bearing unit compact conformation, help to reduce the weight and the size of hub, can obtain best prefastening load, and improve the reliability of hub-bearing unit.
As preferably, described flange neck is provided with a step, and described step and described inner ring small end face are suitable.Like this, the flange raceway groove of band inner ring and outer ring raceway form the symmetric double raceway groove.
The utility model is skillfully constructed, and by the setting of bead structure, makes this hub-bearing unit have compact conformation, in light weight, advantages such as size is little, and promptly volume is little, and inner ring is not easy to produce and endwisely slips, can also obtain best prefastening load, and improve the reliability of hub-bearing unit.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model:
Fig. 2 is the left TV structure scheme drawing of Fig. 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, Fig. 2, the non-driving wheel hub-bearing unit of this routine a kind of roll coil of strip limit structure, comprise flange 1, be connected with wheel hub inner ring 3 on the step of flange neck, the inner ring periphery is connected with wheel hub outer ring 4, is provided with rolling body 5 between inner ring and flange neck step place 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 5, and described flange 1 neck is provided with a step, and described step and described inner ring 3 small end faces are suitable.Wherein, the inner ring 3 large end faces outsides down and be provided with exterior seal ring assembly 2 between the wheel hub outer ring 4, the end face of wheel hub outer ring 4 is provided with several threaded shank holes, rolling body 5 is a steel ball, by retainer 9 fixed positions, one side matches with the double channel of wheel hub outer ring 4, and opposite side is suitable with flange 1 double channel of band inner ring.
Wherein, be provided with seal ring assembly 10 between flange 1 large end face and the wheel hub outer ring 4, it is by the sealing bore interference fit of skeleton and wheel hub outer ring 4, has many lips rubber sealing structure on the skeleton, many lips rubber contacts with flange 1 outer surface, and 10 pairs of whole wheel hub structures of poted assemblies play the effect of exclusion seal, lifelong self-lubricating.
Described flange 1 neck end place is provided with bead structure 6, and there is the slotted hole of certain depth crimping 6 inboards, described bead structure 6 is toward the inner ring 3 large end faces turnover adaptive with it, make the neck end place of flange produce plastic deformation, inner ring 3 and flange 1 are tightened to one, and the diameter of crimping is less than the diameter of inner ring large end face.
It is apparent to one skilled in the art that the utility model can be changed into multiple mode, and such change is not thought and broken away from scope of the present utility model.What all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
