Abstract
The utility model discloses an anti-rotation wheel hub bolt for a vehicle, which has the advantages of simple structure, difficult shedding, easy mounting, good tightness and long service life and comprises a screw rod and a bolt head, wherein one end of the screw rod is fixedly connected in the middle of the bolt head, a stabilizing surface matched with a wheel hub is arranged on one side of the bolt head, the stabilizing surface is an arc-shaped surface, and the radian of the arc-shaped surface tallies with the contacted arc-shaped surface of the wheel hub; and a longitudinal stripe circling the full circumference is arranged on the circumferential surface of the fixed connection section of the screw rod and the bolt head. The arc-shaped surface is arranged at the upper end of the bolt head, planes are arranged on two sides, and corner angles are chamfered.
Description
Technical field
The utility model relates to a kind of bolt, is specifically related to a kind of automobile-used anti-spinning roller hub bolt that is used for fastening automotive hub.
Background technique
Realize being connected by bolt between the wheel hub of automobile and the steel ring, for the convenience of installing and fastening after stability, generally all be provided with stability plane on the side of bolt head, as shown in Figure 1 and Figure 2, cylindrical bolt head 21 is vertically cut a part of circular arc, forms parallel breach, during installation, this stabilising surface 22 leans with the stabilising surface of wheel hub, can prevent that bolt rotates thereupon in the process of lemon jack panel, and fastening back is difficult for loosening.But, the contacted area of the stability plane of this bolt head and wheel hub is too little, in lemon jack panel and wheel rolling, bolt head can constantly rub with the stabilising surface of wheel hub, thereby cause bolt loosening rotation in wheel bore, bolt after loosening very easily is cut off in the wheel process even comes off, thereby causes the appearance of short, situation such as wheel hub is scrapped in boss bolt working life.
Summary of the invention
The automobile-used anti-spinning roller hub bolt that the purpose of this utility model provides a kind of simple in structure, difficult drop-off, installation is easy, tightness good and the life-span is long.
A kind of automobile-used anti-spinning roller hub bolt comprises screw rod and bolt head; One end of screw rod is fixed in the middle part of bolt head, and the first side of bolt is the stabilising surface that cooperates with wheel hub, and this stabilising surface is a cambered surface, and its radian and contacted wheel hub cambered surface match; On affixed section circumferential surface of screw rod and bolt head, offer longitudinal stripe around full week.
The bolt head upper end is a cambered surface, and its both sides are the plane, its edges and corners rounding.
The utility model increases the length of stabilising surface by the shape that changes existing cylindrical bolt head, it is bolt and the area that contacts of wheel hub cambered surface, because the increase of surface of contact, can not rotate after the bolton and get loose, after changing stabilising surface into cambered surface simultaneously, bolt head can better coincide with the wheel hub cambered surface, and bolt is difficult for rotation and damages wheel bore, also can not cut the wheel hub contacting surface.And because the utility model offers the longitudinal stripe around full week on affixed section circumferential surface of screw rod and bolt head, when this longitudinal stripe inserts the wheel hub fixed hole at bolt, meeting and fixedly hole wall formation friction, and be not easy from the wheel hub fixed hole, to deviate from, installation is more prone to.
Description of drawings
Below in conjunction with accompanying drawing a kind of automobile-used anti-spinning roller hub bolt of the utility model is described in detail.
Fig. 1 is the structural representation of existing boss bolt;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of a kind of automobile-used anti-spinning roller hub bolt of the utility model;
Fig. 4 is the plan view of Fig. 3;
Embodiment
As shown in Figure 3, Figure 4, a kind of automobile-used anti-spinning roller hub bolt comprises screw rod 1 and bolt head 2; One end of screw rod 1 is fixed in the middle part of bolt head 2, and bolt head 2 one sides are the stabilising surface 3 that cooperates with wheel hub, and this stabilising surface 3 is a cambered surface, and its radian and contacted wheel hub cambered surface match; On affixed section 4 circumferential surface of screw rod 1 and bolt head 2, offer longitudinal stripe 5 around full week.
The upper end 6 of bolt head 2 cross sections is narrower, is circular arc; Lower end 9 broads are circular arc, and promptly stabilising surface 3;
Bolt head 2 its both sides 7,8 are the plane, its edges and corners rounding.
