Abstract
The utility model discloses a hub bolt for an automobile. The utility model comprises a T-shaped rod part, wherein the vertical part of the rod part is provided with screw threads; the rod part is provided with a polished rod part which is tightly matched with a hub bolt hole to be arranged; the polished rod part is arranged under the horizontal part of the rod part; the screw threads are arranged under the polished rod part and are extended to the polished rod part from the tail end of the rod part; the flange face under the horizontal part is provided with saw teeth; by the interference fit of a polished rod on the T-shaped rod part of a bolt and the bolt hole on a hub, the hub bolt can be prevented from being pressed during assembly. The utility model has the advantages of assembly precision enhancement, equalizing stress and good centering performance. Simultaneously, by a way that the saw teeth are arranged on the flange face under the horizontal part, the hub bolt can be prevented from sliding during the screwing of a hub nut.
Description
[technical field]
The utility model relates to a kind of automobile boss bolt.
[background technique]
The automotive hub bolt is as the part of automotive hub assembly, play crucial effects, existing automotive hub bolt mostly is structure as shown in Figure 1, and this kind bolt is provided with spline 4, cooperates with hub stud holes, because of being subjected to the influence of spline 4, when making bolt in being pressed into hub stud holes, resistance is bigger, easily causes discontinuity equalization, in the assembly manipulation of reality, bolt has is pressed askew phenomenon.
[model utility content]
The utility model provides a kind of boss bolt that prevents to be pressed askew and automobile boss bolt that assembly precision is high when assembling in order to overcome the above problems.
The technological scheme of the utility model technical solution problem is: a kind of automobile boss bolt, comprise T type bar portion, this bar portion vertical portion is provided with screw thread, have and the friction tight polished rod of hub stud holes to be installed portion in the described bar portion, polished rod portion is positioned at the below of bar portion 1 horizontal part, screw thread is positioned at the below of this polished rod portion and extends to this polished rod portion from the end of this bar portion 1, and described horizontal part lower end flanged surface is provided with sawtooth.
Described sawtooth is embedded on the flanged surface of horizontal part lower end.
Described sawtooth along the circumferential direction evenly is arranged on the flanged surface of horizontal part lower end.
The madial wall bore dia that described sawtooth forms is equal to or greater than the outer diameter of polished rod portion.
Adopt the beneficial effect of above scheme: 1) by the polished rod portion in the T type bar portion of bolt and the interference fit of wheel hub upper bolt hole, can prevent that boss bolt from being pressed askewly when assembling, improve assembly precision, and stress equalization, centering property is good; 2) sawtooth that is provided with on the interference power of the interference fit by polished rod and bolt hole and the flanged surface, boss bolt can skid in the time of can preventing to tighten hub nut.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.

Fig. 2 is the plan view of boss bolt among the utility model embodiment.
Fig. 3 is the worm's eye view of boss bolt shown in Figure 2.
Fig. 4 is the stereogram of boss bolt shown in Figure 2.
Fig. 5 is the structural representation after the assembling of boss bolt and wheel hub among the utility model embodiment.
[embodiment]
Extremely shown in Figure 5 as Fig. 2, the utility model automobile boss bolt, comprise T type bar portion 1, this bar portion vertical portion is provided with screw thread, polished rod portion 2 with wheel hub to be installed 6 bolt hole interference fit is arranged in the described bar portion, polished rod portion 2 is positioned at the below of bar portion 1 horizontal part 3, and screw thread is positioned at the below of this polished rod portion 2 and extends to this polished rod portion 2 from the end of this bar portion 1, and described horizontal part 3 lower end flanged surfaces are provided with sawtooth 5.
Described sawtooth 5 is embedded on the horizontal part 3 lower end flanged surfaces, and sawtooth 5 along the circumferential direction evenly is arranged on the horizontal part 3 lower end flanged surfaces, and the madial wall bore dia that described sawtooth 5 forms is equal to or greater than the outer diameter of polished rod.
Working procedure:
With pressure unit boss bolt is pressed in wheel hub 6 bolts hole during assembling, and make the sawtooth part on sending out face blue embed boss bolt end face (as shown in Figure 2), because polished rod portion of bolt shank 12 and bolt hole interference fit (the polished rod portion here is meant the smooth surface with the smooth outer surface of machine tooling or finish forge), therefore, when assembling, centering property is good, stress equalization when being pressed into, thereby assembly precision height; The utility model replaces spline with the sawtooth on the bolt shank horizontal part 3 lower end flanged surfaces, can play the effect that prevents that bolt from trackslipping equally, so by the acting in conjunction of interference power and sawtooth, boss bolt can not skid when tightening hub nut.
