Description
Technical field
The utility model relates to a kind of fastening piece, is specifically related to a kind of stationary hub wheel bolt.
Background technique
Wheel bolt connects the requisite parts of wheel, needs the large torsion born between automotive hub with axletree to be connected, so have higher requirement to the bearing capacity between screw rod.
The wheel bolt that connection between the two panels wheel hub of existing truck side all adopts wheel place to connect wheel hub connects.As shown in Figure 1, existing wheel bolt comprises screw rod and nut, the screw rod of wheel bolt forms by two sections, comprise inner screw 1 and external screw rod 2, the shaft shoulder 5 of isolation two sections is provided with between inner screw and external screw rod, inner screw and external screw rod comprise respectively with externally threaded screw section and ganoid joint, inner screw are connected with the inner nut 3 that has been threaded, and external screw rod are socketed with nut collar 6 and are fixedly connected with outer nut 4.The inner screw of this wheel bolt is fixedly connected with axletree steel ring by inner nut, the joint socket two panels wheel hub of external screw rod, be fixedly connected with by outer nut after putting nut collar, because two panels wheel hub is directly connected, when outer nut loosens, produce Relative friction between two panels wheel hub to slide, cause between wheel hub and mutually wear and tear, reduce the working life of wheel hub.And existing bolt is generally minor diameter, screw rod adopts swivel nut form to be interconnected, though this swivel nut form easy processing, easily rupture, working life is shorter.
Model utility content
The purpose of this utility model is to provide a kind of barrier propterty good, inexpensive stationary hub wheel bolt.
In order to reach the purpose of this utility model, technological scheme is as follows:
A kind of stationary hub wheel bolt, comprise the screw rod be made up of inner screw and external screw rod, it is characterized in that: between described inner screw and external screw rod, be provided with the shaft shoulder, the circumferential surface of the described shaft shoulder is provided with the first groove, described external screw rod is arranged with swivel nut, and the circumferential surface of described swivel nut has the second groove.
Further, along the axial direction of the described shaft shoulder, the surface of described first groove is provided with projection.
Further, along the axial direction of described swivel nut, the surface of described second groove is provided with projection.
Further, the sectional shape of described first groove and the second groove is any one in circular arc, taper shape or ellipse.
The beneficial effect that the utility model has:
That can strengthen wheel hub is fastening, and two panels wheel hub is separately fastening, can not produce Relative friction, prevents wheel hub to wear and tear, and extends the use longevity of wheel hub.And total is rationally compact to design, can prevent from skidding, tightness is good,
Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of existing stationary hub wheel bolt;
Fig. 2 is the cross section structure schematic diagram of the utility model stationary hub wheel bolt.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
As shown in Figure 2, a kind of stationary hub wheel bolt, comprises the screw rod be made up of inner screw 8 and external screw rod 10, and one end of inner screw 8 is arranged with inner nut 7, and one end of external screw rod 10 is arranged with outer nut 14.
Be provided with the shaft shoulder 9 between inner screw 8 and external screw rod 10, the circumferential surface of the shaft shoulder 9 is provided with the first groove 11, and along the axial direction of the shaft shoulder 9, the surface of the first groove 11 is provided with projection, and projection can increase frictional force, prevents from skidding, and increases fastening force.The sectional shape of the first groove 11 and the second groove 13 is any one in circular arc, taper shape or ellipse, and the present embodiment is circular arc.First groove 11 is for fastening wherein a slice wheel hub, and the shaft shoulder 9 both as isolation inner screw 8 and external screw rod 10 use, used as fastening wheel hub again, and made total compacter.
External screw rod 10 is arranged with swivel nut 12, the circumferential surface of swivel nut 12 has the second groove 13, and along the axial direction of swivel nut 12, the surface of the second groove 13 is provided with projection, and projection can increase frictional force, prevents from skidding, and increases fastening force.The sectional shape of the second groove 13 is any one in circular arc, taper shape or ellipse, and the present embodiment is oval.Second groove 13 is for another sheet wheel hub fastening.
In addition, in the present embodiment, the shaft shoulder 9 and swivel nut 12 are all the structures of one, certainly they also can be the results of split, such as in fig. 2 shown in, by the shaft shoulder 9 and swivel nut 12 from middle " incisions " formation two symmetrical structures, assemble formation entirety again, this can increase the using scope of the shaft shoulder 9 and swivel nut 12, for the wheel hub of fastening different size, more flexibly.
Last it is noted that above embodiment only in order to illustrate the utility model and and technological scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
