Abstract
The utility model discloses a wheel bolt for connection and fixation of a wheel spoke and a hub of a vehicle. The wheel bolt comprises a head part comprising a support face and an anti-rotation positioning face; a through hole is formed between the support face and the anti-rotating positioning face; the anti-rotating positioning face is positioned below the support face and is arc-shaped. The wheel bolt for the connection and fixation of the wheel spoke and the hub of the vehicle can enlarge the firming capacity of the support face of the bolt, and the bolt can be prevented from being rotated to be loosened relative to the hub in multiple firming and loosening of the repeated use process.
Description
Technical field
The utility model relates to a kind of bolt, particularly relates to a kind of wheel bolt that is connected and fixes with wheel hub for the automobile spoke.
Background technique
Automobile generally adopts some bolts of fixed installation on hub for vehicle wheel in the prior art, wheel hub and spoke for connection and fixing vehicle wheel, power is delivered to spoke by the rotation of wheel hub, thereby the tyre rotation that spoke is firmly connected is travelled vehicle.As an essential condition of this power transmission chain, be between the hub and spokes contact plane, rely on bolt, nut is firm and the frictional force that produces.Thereby, realize that bolt, nut are reliably firm to spoke and wheel hub, most important, this firm be to rely on bolt bearing face and the clamping of nut support in the face of hub and spokes to realize, so the bearing value of bolt bearing face is one of key factor that ensures firm function realization.
In present technology, for traditional Technical Economy reason, bolt head is often made cylindrical.The fitting surface of bolt is plane, and the round platform on the wheel hub that prevents the bolt rotation of relying is columniform one section, is arc, and therefore, it is that line contacts with this round platform cylndrical surface that bolt is cut flat, thereby there is the possibility of left and right minor rotation in bolt.When the supporting surface of bolt less, when firm power is on the low side, bolt may be repeated fastened, with respect to wheel hub, rotate in tearing loose process open, thereby cause that whole bolt, nut connect loosening.In actual use, this kind phenomenon happens occasionally, and the most serious situation is to cause that bolt splits off, wheel comes off, and causes the serious accident of automobilism.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wheel bolt that is connected and fixes with wheel hub for the automobile spoke, the firm ability that it can increase the bolt bearing face, prevent simultaneously bolt be repeatedly used firm with tear pine open in rotate and with respect to wheel loose on axle.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of wheel bolt that is connected and fixes with wheel hub for the automobile spoke, it is characterized in that, it comprises head, head comprises supporting surface and anti-rotation locating face, between supporting surface and anti-rotation locating face, be provided with a through hole, the anti-rotation locating face is positioned at the below of supporting surface, the anti-rotation locating face be shaped as cambered surface.
Preferably, described supporting surface is shaped as shaped face.
Preferably, described head also comprises fitting surface, and the angle of fitting surface and horizontal plane is 30 degree.
Positive progressive effect of the present utility model is: the utility model adopts the bolt head that can match with the circumference of hub face, determine bolt head relatively with wheel hub surely close, stable, prevent bolt repeatedly repeat fastening and tear pine open in loosening with respect to the wheel hub face that rotates; While bolt head supporting surface abnormity sphere, can increase the firm ability of bolt bearing face, make bolt head and wheel hub location reliable, reduce bolt and the generation of wearing and tearing, security incident situation in installing and working, occurs rotating, determine the safety of automobile, extend the working life of bolt and wheel hub.
The accompanying drawing explanation
Fig. 1 is that the utility model is connected with wheel hub for the automobile spoke and the structural representation of the wheel bolt head fixed.
Fig. 2 is the structural representation that the utility model is connected with wheel hub for the automobile spoke and the wheel bolt fixed and circumference of hub face match.
Fig. 3 is that the utility model is connected with wheel hub for the automobile spoke and the plan view of the wheel bolt fixed.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
as Fig. 1, Fig. 2 and shown in Figure 3, the utility model is connected with wheel hub for the automobile spoke and the wheel bolt fixed comprises head 1, head 1 comprises supporting surface 11 and anti-rotation locating face 12, between supporting surface 11 and anti-rotation locating face 12, be provided with a through hole 15, anti-rotation locating face 12 is positioned at the below of supporting surface 11, anti-rotation locating face 12 be shaped as cambered surface, anti-rotation locating face 12 can match with a circumference of hub face 3 like this, guarantee that bolt head is combined stable with wheel hub, become the location of cambered surface to the wheel hub cylndrical surface, prevent bolt repeatedly repeat fastening with tear pine open in rotate, the rotation possibility that structure may exist is eliminated, thereby eliminated bolt owing to rotating loosening possibility occurs with respect to wheel hub.
supporting surface 11 be shaped as shaped face, the possible space that utilizes like this bolt to install on wheel hub, the bearing area that adds as much as possible king-bolt, supporting surface is lacked to shape by circle and be improved to approximate rectangular semicircle, when overall sizes is basic identical, abnormity supporting surface area is more circular to be cut flat and increases approximately 30%, effectively improve bolt and born fastening ability, increased the fastening ability of bolt bearing face, make No.1 of bolt reliable with the wheel hub location, reduce bolt and wearing and tearing in installing and working, occur rotating, the generation of security incident situation, determine the safety of vehicle, extend the working life of bolt and wheel hub.
The utility model is connected with wheel hub for the automobile spoke and the wheel bolt fixed also comprises body 2, and head 1 is fixed on a side of body 2.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
Claims (2)
1. wheel bolt that is connected and fixes with wheel hub for the automobile spoke, it is characterized in that, it comprises head, head comprises supporting surface and anti-rotation locating face, between supporting surface and anti-rotation locating face, be provided with a through hole, the anti-rotation locating face is positioned at the below of supporting surface, the anti-rotation locating face be shaped as cambered surface, described head also comprises fitting surface, and the angle of fitting surface and horizontal plane is 30 degree.
2. the wheel bolt that is connected and fixes with wheel hub for the automobile spoke as claimed in claim 1, is characterized in that, described supporting surface be shaped as shaped face, described shaped face is approximate rectangular semicircle.
