Abstract
The utility model discloses a fastening structure which comprises a first part and a second part. A first through hole is formed in the first part. A second through hole is formed in the second part. The first part and the second part are connected with a nut through a bolt. The bolt penetrates through the first through hole and the second through hole and is in a screw thread fit with the nut, wherein a head part of the bolt presses and leans on the first part, a rod part of the bolt is in a tight match with the first through hole, and the nut presses tightly on the second part. Due to the fact that the rod part and the first through hole are in the tight match, friction between the rod part and the first through hole is increased, the first part exerts lateral force to the rod part, the phenomenon that the bolt rotates together with the nut when the nut is tighten up is avoided, and therefore installation efficiency of the nut is improved, tighten up force of the nut is increased,and the nut can press tightly on the second part. Besides, the utility model further discloses a suspension system with the fastening structure and a vehicle which includes the suspension system.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that do opposite explanation, the noun of locality of use typically refers to upper and lower in the accompanying drawing such as " upper and lower ", and " inside and outside " refers to inside and outside with respect to spare part profile.
Referring to Fig. 1, the utility model relates to a kind of fastening structure, this fastening structure comprises first component 1, second component 3, bolt 5 and nut 6, wherein, be provided with the first through hole 2 on the first component 1, be provided with the second through hole 4 on the second component 3, bolt 5 passes behind the first through hole 2 and the second through hole 4 and nut 6 carries out screw thread fit, so that first component 1 and second component 3 are linked together.
Narrow and small and can not use in the situation of the clamping device that prevents transfer at installing space, bolt 5 together rotates with nut 6 and cause can't fastening nut 6 in order to prevent from connecting first component 1 and second component 3, the utility model can make the head 51 of bolt 5 be pressed against on the first component 1, and makes the bar section 52 of bolt 5 and the first through hole 2 form flush fit.Because this flush fit can increase the friction between the first through hole 2 of the bar section 52 of bolt 5 and first component 1, so that the bar section 52 of 1 pair of bolt 5 of first component applies side force, avoided the phenomenon of bolt 5 transfers, improved the installation effectiveness of nut 6, and increased the screwing force of nut 6, nut 6 can be pressed on the second component 3.In addition, when unscrewing nut 6 along the direction opposite with tightening direction, because the bar section 52 of bolt 5 and the friction between the first through hole 2, so that be more convenient for removing nut 6.
Be appreciated that in the said structure that the first through hole 2 and the flush fit of bar section 52 can be accomplished in several ways, for example, flush fit can be interference fit, and namely the diameter of bar section 52 is a bit larger tham the internal diameter of the first through hole 2, makes it to form interference fit.Or, can form in the part that bar section 52 and the first through hole 2 match outside thread (this outside thread has opposite hand of spiral with the screw thread that matches with nut 6), form the negative thread that matches at the first through hole 2 simultaneously, thereby realize the flush fit structure.
Preferably, the utility model is formed with at the internal face of the first through hole 2 and is used to form friction tight groove or annular knurl 21, perhaps the outer peripheral face in the bar section 52 of bolt 5 forms above-mentioned groove or annular knurl 21, perhaps forms above-mentioned groove or annular knurls 21 at the internal face of the first through hole 2 and the bar section 52 of bolt 5 simultaneously.The setting of above-mentioned groove or annular knurl 21 is all for increasing the friction force between the first through hole 2 and the bar section 52.In the specific embodiment as shown in Figure 1, described groove or annular knurl 21 only form at the internal face of the first through hole 2, so that processing.
Wherein, described groove or annular knurl 21 can be formed on the internal face of the first through hole 2 at least in part, also can be formed on the whole internal face of the first through hole 2.This can select according to the installation needs of reality, and the utility model does not limit this.In the specific embodiment that Fig. 1 shows, groove or annular knurl 21 are formed on the whole internal face of the first through hole 2, namely upwards and down extend to respectively upper surface and the lower surface of first component 1.In addition, described groove or annular knurl 21 refer to the dentation of vertical bar shaped, or netted annular knurl, still, are not limited to this two kinds of concrete structures, and those skilled in the art can be to adopting multiple groove or knurling structure, to increase friction force.
In addition, in the situation that the first through hole 2 can prevent bolt 5 transfers, can make the diameter of the second through hole 4 greater than the external diameter of the bar section 52 of bolt 5, because the aperture of the second through hole 4 is relatively large, reduce the accuracy of manufacture of the second through hole 4, namely can more easily make the second through hole 4.
Referring to Fig. 2, in the specific embodiment of the present utility model, first component 1 can be flange, refer in particular to the clamp flange of ball end assembly, second component 3 can be rocking arm, and suspension arms bulb 7 is connected with rocking arm by flange, particularly, suspension arms bulb 7 is fixed on the first bight 11 of flange, is respectively arranged with the first through hole 2 on the second bight 12 of flange, third angle section 13 and the 4th bight 14, be provided with on the rocking arm with flange on each the first through hole 2 corresponding second through holes 4.By making three bolts 5 pass the first through hole 2 and the second through hole 4, and show respectively with among three nut 6(Fig. 2) behind the screw thread fit, flange and swing arm are linked together, and then being connected of realization suspension arms bulb 7 and rocking arm.
Based on the above-mentioned specific embodiment, the utility model can relate to a kind of suspension system, comprises above-mentioned fastening structure for flange and rocking arm in this suspension system.In addition, the utility model can also relate to a kind of vehicle, and this vehicle comprises suspension system.Behind the vehicle that adopts above-mentioned fastening structure, the vehicle efficiency of assembling that can improve.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove in addition, each concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode, for fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.As long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
