Abstract
The utility model discloses an automobile hub bolt structure which comprises a hub, a rim and a self-aligning assembly, wherein a plurality of conical holes are uniformly distributed on the rim along the circumferential direction of the rim, threaded holes are formed in positions, corresponding to the conical holes, of the hub, the hub abuts against the rim, the self-aligning assembly is arranged in the conical holes, the self-aligning assembly comprises a bolt and a self-aligning taper sleeve, the self-aligning taper sleeve is sleeved at the lower end of the head of the bolt and is in clearance fit with the rod portion of the bolt, the self-aligning taper sleeve is in taper fit with the conical holes, and the bolt is connected with the threaded holes. The mounting structure can effectively prevent the phenomenon that the bolt is loosened due to the fact that the eccentric is generated when the conical surfaces are matched due to the error of the position degree.
Description
Technical Field
The utility model relates to an automobile hub bolt structure.
Background
The automobile hub mounting structure generally comprises a hub bolt, a rim and a hub, wherein the hub bolt is provided with an outer conical surface, a plurality of inner conical holes matched with the hub bolt are uniformly and equally distributed along the center of the hub, a plurality of threaded holes are uniformly and equally distributed along the center of the hub, the manufacturing accuracy limiting position degree is only as low as possible, and due to the position degree error, the conical surface matching is eccentric, so that the matching is not tight, and the bolts are loosened.
Disclosure of Invention
Aiming at the defects existing in the prior art, the utility model aims to provide an automobile hub bolt structure which solves the problem that the eccentric thread looseness occurs in conical surface matching.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides an automobile hub bolt structure, includes wheel hub, rim, aligning subassembly, a plurality of circular conical holes of rim along its circumference equipartition, wheel hub butt rim and wheel hub correspond the position of circular conical hole and all are equipped with the screw hole, aligning subassembly installs in the circular conical hole, aligning subassembly includes bolt, aligning taper sleeve cover establish the lower extreme at the bolt head and with bolt shaft portion clearance fit, aligning taper sleeve adopts taper fit with the circular conical hole, the bolt is connected with the screw hole.
As a further improvement of the utility model, the screw thread on the bolt is formed by extrusion, and the major diameter of the screw thread is not smaller than the inner diameter of the aligning taper sleeve.
As a further improvement of the utility model, the length of the shaft section of the bolt for installing the aligning taper sleeve is not smaller than the axial length of the aligning taper sleeve.
As a further improvement of the utility model, the end face of the wheel hub, which is abutted against the wheel rim, is provided with a positioning column, the face of the wheel rim, which is opposite to the positioning column, is provided with a positioning hole matched with the wheel rim, and the positioning column is arranged in the positioning hole.
The utility model has the beneficial effects that: the phenomenon that the bolt is loosened due to eccentricity generated during conical surface matching caused by the error of the position degree is effectively prevented.

FIG. 2 is a schematic cross-sectional view of a centering assembly of the present utility model.
Reference numerals: 1. a hub; 2. a rim; 3. a bolt; 4. a self-aligning taper sleeve; 5. positioning columns; 6. and positioning holes.
Detailed Description
The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.
Referring to figures 1-2, an automobile hub bolt structure comprises a hub 1, a rim 2 and a aligning assembly, wherein a plurality of conical holes are uniformly distributed on the rim 2 along the circumferential direction of the rim, the hub 1 is abutted against the rim 2, the positions of the hub 1 corresponding to the conical holes are respectively provided with a threaded hole, the aligning assembly is arranged in the conical holes, the aligning assembly comprises a bolt 3 and an aligning taper sleeve 4, the aligning taper sleeve 4 is sleeved at the lower end of the head of the bolt 3 and is in clearance fit with the rod part of the bolt 3, the aligning taper sleeve 4 is in taper fit with the conical holes, thus the bolt 3 is only responsible for locking and is not responsible for positioning, the aligning taper sleeve 4 can be movably and automatically aligned due to a clearance between the aligning taper sleeve 4 and the rod part of the bolt 3, the cooperation of conical surface has been guaranteed, bolt 3 is connected with the screw hole, screw thread on the bolt 3 is extrusion, and the major diameter of screw thread is not less than the internal diameter of aligning taper sleeve 4, sets up like this and prevents that aligning taper sleeve 4 from deviating from bolt 3 when the installation, the length that is used for installing the axial length of aligning taper sleeve 4 on the bolt 3 is not less than aligning taper sleeve 4 axial, sets up like this and prevents that aligning taper sleeve 4 from appearing the dead phenomenon of card in the axial, be equipped with reference column 5 on the terminal surface of wheel hub 1 butt rim 2, be equipped with rather than complex locating hole 6 on the face of rim 2 relative reference column 5, reference column 5 installs in locating hole 6.
The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
