Abstract
The utility model discloses a kind of half shaft bearing block check bolt, the flat shim and spring washer piece, threaded shank, threaded portion and nut abutted successively including bolt head, with bolt head, the threaded shank is trapezoidal cylinder body, the threaded shank outer end is provided with the expansion collar, the nut is provided with Clip Reed, the side end face of the threaded portion is provided with neck, and the Clip Reed is caught in after nut is tightened in corresponding neck.The utility model half shaft bearing block check bolt, by the way that threaded shank is set into trapezoidal cylinder body and the expansion collar is set in threaded shank outer end so that increase and the frictional force of bearing base inner surface after bolt is tightened, so as to realize locking effect；Meanwhile, neck is set on the side end face of threaded portion and Clip Reed is set on nut, Clip Reed is caught in corresponding neck after nut is tightened, the locking effect of nut is again increased, so that it is guaranteed that the connection reliability of bolt and bearing block.
Description
Technical field
The utility model belongs to automobile technical field, more particularly to a kind of half shaft bearing block check bolt.
Background technology
Automobile axle shaft be realize running car turn a strength member, it is connected with the wheel of automobile, with car
Bearing block is provided with during wheel connection, bearing block plays a part of supporting semiaxis, and connecting bolt one end thereon is and automobile chassis
Corresponding site is connected, and the other end is connected with wheel corresponding site, because automobile can produce relative movement with the bolt under steam,
And the failure of the bolt will cause serious consequence.Great property loss is not only caused, but also there is the huge of casualties
Risks, topmost harm is that wheel flies out vehicle in the process of moving, and then leads to the miserable of casualties and property loss
Play, it is therefore, particularly significant to the locking Capability Requirement of the bolt in automobile making.
That connection is screwed by spring washer, nut and bolt mostly for common bolt connection, however, these spring washers with
Bolt body is separated, the easy neglected loading in assembling, and also easily lost when repairing and changing that reliability is not high；Meanwhile, it is general
Logical screw thread is all that screw thread cusp is set into plane, is easily worked, and such threaded connection engagement system contacts for point, contact surface
Product is small, and frictional force is small, inadequate for the anti-loose ability of bolt, also easily causes the generation of accident.
Utility model content
Technical problem to be solved in the utility model is to provide one kind and can improve thread contact face can improve bolt again
Half shaft bearing block check bolt easy to installation and maintenance.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of half shaft bearing block check bolt, including bolt head, the flat shim and spring washer that are abutted successively with bolt head
Piece, threaded shank, threaded portion and nut, the threaded shank are trapezoidal cylinder body, and the threaded shank outer end is described provided with the expansion collar
Nut is provided with Clip Reed, and the side end face of the threaded portion is provided with neck, and the Clip Reed is caught in accordingly after nut is tightened
Neck in.
Further, the spring washer piece is the spring part of multi-turn coiling.
Further, the tilt angles of the threaded shank are 5 °~15 °, and the major part position of threaded shank is close to bolt head one
End.
Further, the expansion collar is elastic component.
Further, the Clip Reed and neck are distributed on the circumference of nut end face and screw thread end surface respectively.
Beneficial effect：The utility model half shaft bearing block check bolt, by by threaded shank be set to trapezoidal cylinder body and
Threaded shank outer end sets the expansion collar so that increase and the frictional force of bearing base inner surface after bolt is tightened, so as to realize locking
Effect；Meanwhile, neck is set on the side end face of threaded portion and Clip Reed is set on nut, by jump ring after nut is tightened
Piece is caught in corresponding neck, again increases the locking effect of nut, so that it is guaranteed that the connection reliability of bolt and bearing block.
Brief description of the drawings
Fig. 1 is a kind of structural representation of half shaft bearing block check bolt of the utility model.
Fig. 2 is the sectional view of the screw thread of half shaft bearing block check bolt in Fig. 1.
Fig. 3 is the left view of half shaft bearing block check bolt in Fig. 1.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1 to Figure 3, a kind of better embodiment of half shaft bearing block check bolt of the utility model includes bolt
Head 1, flat shim 2 and spring washer piece 3, threaded shank 4, threaded portion 5 and the nut 6 abutted successively with bolt head 1, the threaded shank
4 be trapezoidal cylinder body, and the outer end of threaded shank 4 is provided with Clip Reed 60, the threaded portion provided with the expansion collar 7, the nut 6
5 side end face is provided with neck 50, and the Clip Reed 60 is caught in after nut 6 is tightened in corresponding neck 50.Flat shim 2 and bullet
The effect of pad 3 is to play to reduce the gap that the irregularity degree between bolt head 1 and bearing block is brought, bolt in increase use
Friction between head 1 and bearing block, so as to play locking effect；And the threaded shank 4 of trapezoidal cylinder body and it is arranged on spiral shell
The expansion collar 7 of the outer end of bar portion 4, be in order to when tightening bolt, by the major part position extrusion expansion collar 7 of threaded shank 4 from
And increase its contact surface and frictional force with bearing seat inner surface, realize locking effect；The Clip Reed 60 set on nut 6
The neck 50 set with the end face of threaded portion 5, also for after nut 6 is tightened, Clip Reed 60 is caught in the neck of correspondence position
50, prevent that nut 6 loosens in use, so as to cause to produce loosening between bolt and bearing block, influence using effect.
In order to preferably play locking effect, the gap between bolt head 1 and bearing block, the spring washer piece are reduced as far as possible
3 be the spring part of multi-turn coiling.
In order to realize the effect of the extrusion expansion collar 7 of threaded shank 4, and also to bolt can be installed smoothly, the spiral shell
