Abstract
The utility model discloses a hub bolt for preventing revolving of a vehicle, which comprises a screw rod and a bolt head. As the circumference surface of a fixed connecting section between the screw rod and the bolt head of the bolt provided by the utility model is provided with a vertical stripe surrounding the whole circumference, when the bolt is inserted into a fixing hole on the hub, friction is generated between the vertical stripe and the wall of the fixing hole and the bolt is incapable of falling from the fixing hole on the hub, so that the installation is easier. The utility model also discloses a hub nut for preventing revolving of the vehicle. The nut consists of a screw connecting part and a leading part; wherein, one end of the leading part is movably sheathed on the screw connecting part; the external edge of the leading part can be inserted into a sunken hole on the hub bolt in advance, so that when the bolt and the nut are screwed tightly, the hub can be corrected, and the installation can be more convenient and faster.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly relates to a kind of automobile-used anti-wheel hub bolt and nut that revolves.
Background technique
The wheel hub of truck with realize being connected by bolt 1 ' and nut spiral shell 2 ' (shown in Figure 1A) between the steel ring.For the convenience of installing and fastening after stability, generally all be provided with stability plane 12 ' (shown in Figure 1B) on the side of bolt 1 ' head 11 ', cylindrical bolt head 11 ' is vertically cut a part of circular arc, form parallel breach (shown in Fig. 1 C), the stabilising surface of this stability plane 12 during installation ' with wheel hub 10 ' lean (shown in Fig. 1 D), can prevent to rotate at fastening nut 2 ' process in bolt 1 ' thereupon, fastening back is difficult for loosening, but ' ' ' contacted area is too little with wheel hub 10 for the stability plane 12 of portion for this bolt head 11, fastening nut 2 ' process in bolt head 11 ' portion can cut wheel hub 10 ' stabilising surface (dotted portion among the figure), thereby cause bolt 1 ' in wheel hub 10 ' loosening rotation in the hole, ' very easily be cut off under the situation of alternate load, ' ' working life is short for bolt 1 thereby cause wheel hub 10 for bolt 1 after loosening, wheel hub 10 ' scrappage height.
The model utility content
The purpose of this utility model is to provide a kind of difficult drop-off, good, the easy automobile-used anti-wheel hub bolt and nut that revolves of assembling of tightness.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of automobile-used anti-spinning roller hub bolt, comprises screw rod and bolt head, and an 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; On affixed section circumferential surface of screw rod and bolt head, offer longitudinal stripe around full week.
The top of described bolt head is trapezoid shaped, and the stabilising surface that the bottom cooperates with wheel hub is an arc surface.
The utility model is a kind of automobile-used anti-spinning roller hub nut, and it is made up of spiro union portion and guide portion; The central authorities of described spiro union portion have tapped hole, and the one end has the flange that extends radially outward; Described guide portion inner chamber is made of an annular groove and the pilot hole and the spacing hole that connect with these annular groove two ends respectively, annular groove and pilot hole, annular groove and spacing hole form shoulder hole, the flange on the described spiro union portion is movable be nested with in annular groove and the interior edge face holding of flange on the step surface of annular groove and spacing hole.
After adopting such scheme, the utlity model has following advantage:
1, because the utility model bolt 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, can form friction with the fixed hole hole wall, and be not easy to deviate from from the wheel hub fixed hole, installation is more prone to.
2, form by spiro union portion and guide portion owing to nut of the present utility model, one end of guide portion is actively socketed on the spiro union portion, and the outer rim of guide portion can be inserted in the hub nut counterbore, when bolts and nuts screw tight in advance, the wheel hub correcting can be made that installation is more convenient, fast.
3, because the stabilising surface that the utility model bolt head bottom cooperates with wheel hub is an arc surface, increased the length of stabilising surface and wheel hub cambered surface, be that area of contact increases, be not easy after the bolton to get loose, the cambered surface of the stabilising surface of arc and wheel hub is more identical simultaneously, can not damage the wheel hub fixed hole because of the rotation of bolt.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Embodiment
As Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises bolt 1 and nut 2 as a complete fastener, and during installation, bolt 1 is screwed onto in the screw 20 of nut 2 central authorities.
As shown in Figure 2, the utility model is automobile-used anti-spinning roller hub bolt 1, and it comprises screw rod 11 and bolt head 12, and an end of screw rod 11 is fixed in the middle part of bolt head 12, the top 121 of bolt head 12 is trapezoid shaped, and the stabilising surface 122 that the bottom cooperates with wheel hub is arc surface (as shown in Figure 7).Offer the longitudinal stripe 111 around full week on affixed section circumferential surface of screw rod 11 and bolt head 12, these longitudinal stripe 111 meetings and wheel hub fixed hole hole wall form and rub, and make that bolt 1 is not easy to deviate from from the wheel hub fixed hole.
As Fig. 5, shown in Figure 6, the utility model is a kind of automobile-used anti-spinning roller hub nut 2, and it is made up of spiro union portion 21 and guide portion 22.The central authorities of described spiro union portion 21 have tapped hole 211, and the one end has the flange 212 that extends radially outward; Described guide portion 22 inner chambers are made of an annular groove 221 and the pilot hole 222 and the spacing hole 223 that connect with these annular groove 221 two ends respectively, and annular groove 221 forms shoulder holes with pilot hole 222, annular groove 221 with spacing hole 223.Flange 212 on the described spiro union portion 21 is movable be nested with in annular groove 221 and the interior edge face holding of flange 212 on the step surface of annular groove 221 and spacing hole 223, make guide portion 22 relatively spiro union portion 21 radially and axial float and can from annular groove 221, not deviate from.The socket of spiro union portion 21 and guide portion 22 can be nested with in annular groove 221 flange 212 activities on the spiro union portion 21 by the cold hobbing mode spacing hole 223 that closes up.
