Description
Technical field
This utility model is related to automotive field, particularly to a kind of torsion-bar spring adjustment bolt mounting structure and automobile.
Background technology
Car load pose adjustment bolt is that torsion-bar spring adjusts indispensable one of car load attitude as the car load of suspension spring
Individual part, its principle is, by adjusting the exposed length of adjustment bolt, to control the torsional deflection amount of torsion-bar spring, thus controlling
Torsion-bar spring elastic force, raises and reduces vehicle body, thus adjusting car load height.Due to torsion-bar spring torsional deflection angle very
Greatly, wheel and suspension system upper jump in the process of moving and the lower elastic force jumping torsion-bar spring all act in adjustment bolt.By
Very big in its stress amplitude, and the part that connected of whole bolt nonrigid, but some is hanging, so
Examination to the fatigue life of bolt is very harsh, and its root is susceptible to fracture in vehicle road test.
Utility model content
This utility model provides a kind of torsion-bar spring adjustment bolt mounting structure and automobile, its purpose is to solve to turn round
The short problem of the service life of bar spring adjustment bolt.
In order to achieve the above object, embodiment of the present utility model provides a kind of torsion-bar spring adjustment bolt and installs knot
Structure, including：
Bolt body, described bolt body includes bolt head and stud, and described bolt head is set with the junction of described stud
It is equipped with a chamfering structure；
Cushion block, described cushion block is provided with a through hole, and described cushion block is set on described bolt body by described through hole,
And it is provided with, in described through hole, the groove matching with described chamfering structure, described cushion block passes through described groove and described bolt head
Fit.
Wherein, described bolt body is arranged on the installation in the hole of automobile frame, and described cushion block and described automobile frame phase
One end of laminating is set to the arc structure matching with described installing hole.
Embodiment of the present utility model additionally provides a kind of automobile, including the torsion-bar spring adjustment spiral shell described in above-described embodiment
Bolt mounting structure.
Such scheme of the present utility model has following beneficial effect：
Torsion-bar spring adjustment bolt mounting structure described in above-described embodiment of the present utility model and the stud root of automobile
Chamfer design bigger than standard component, also increase chamfering at matched cushion block hole cooperation, the intensity of bolt root can be made
Significantly improve, greatly reinforced the fatigue life of bolt root, increased the reliability of system, thus improving the longevity of whole system
Life, turn avoid the increase diameter of bolt and causes cost to increase, and alleviate weight.

Specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
This utility model is for the short problem of the service life of existing torsion-bar spring adjustment bolt, there is provided a kind of torsion bar
Spring adjustment bolt mounting structure and automobile.
As shown in Figures 2 and 3, embodiment of the present utility model provides a kind of torsion-bar spring adjustment bolt mounting structure,
Including：Bolt body 1, described bolt body 1 includes bolt head and stud, and described bolt head is arranged with the junction of described stud
There is a chamfering structure；Cushion block 2, described cushion block 2 is provided with a through hole 4, and described cushion block 2 is set in described by described through hole 4
On bolt body 1, and in described through hole 4, it is provided with the groove 5 matching with described chamfering structure, described cushion block 2 passes through described
Groove 5 is fitted with described bolt head.
Torsion-bar spring adjustment bolt mounting structure described in above-described embodiment of the present utility model is by the hexagonal of bolt root
Head is designed as non-standard component, smaller, and when such car load travels, bolt rocks turret head and tilts, because turret head becomes
Little, identical in shaking volume, in the case of force value identical, after little turret head tilting, the arm of force of bolt root is reduced, bolt root
Institute's just corresponding reduction loaded；And by coordinating bigger than standard component for the chamfer design of stud root, matched cushion block 2 hole
The chamfering of the groove 5 at place also increases, and described cushion block 2 is fitted by described groove 5 and described bolt head, can make bolt root
Intensity significantly improve, greatly reinforced the fatigue life of bolt root, increased the reliability of system, thus improve whole being
In the life-span of system, turn avoid the increase diameter of bolt and cause cost to increase, and alleviate weight.
As shown in figure 1, described bolt body 1 is arranged on the installation in the hole of automobile frame 3, and described cushion block 2 and described vapour
One end that vehicle carriage 3 fits is set to the arc structure matching with described installing hole.
Bolt body 1 described in above-described embodiment of the present utility model is arranged on the installation in the hole of automobile frame 3, and described
Cushion block 2 is arranged on the installation in the hole of described automobile frame 3 together with described bolt body 1, by described cushion block 2 and described Automobile
One end that frame 3 fits is set to the arc structure matching with described installing hole, makes described cushion block 2 and described automobile frame 3
That fits is even closer, so that the intensity of bolt root significantly improves, has greatly reinforced the fatigue life of bolt root, increases
The reliability of system.
Embodiment of the present utility model additionally provides a kind of automobile, including the torsion-bar spring adjustment spiral shell described in above-described embodiment
Bolt mounting structure.
Torsion-bar spring adjustment bolt mounting structure described in above-described embodiment of the present utility model and the stud root of automobile
Chamfer design bigger than standard component, also increase chamfering at matched cushion block 2 hole cooperation, the intensity of bolt root can be made
Significantly improve, greatly reinforced the fatigue life of bolt root, increased the reliability of system, thus improving the longevity of whole system
Life, turn avoid the increase diameter of bolt and causes cost to increase, and alleviate weight.
The above is preferred implementation of the present utility model it is noted that ordinary skill for the art
For personnel, on the premise of without departing from principle described in the utility model, some improvements and modifications can also be made, these improvement
Also should be regarded as protection domain of the present utility model with retouching.
