Specific implementation mode
The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and this practicality cannot be limited with this
Novel protection domain.
Fig. 1 is the structural schematic diagram for automotive suspension apparatus of the embodiments of the present invention, and Fig. 2 is the utility model
Embodiment the structural schematic diagram for turning the components such as device for the torsion-bar spring of automotive suspension apparatus, link mechanism and limit.Such as Fig. 1
Shown in Fig. 2, which includes vehicle bridge main body 1, swing arm 2, damper 3, torsion-bar spring 4, connecting rod machine
Structure 5 and limit turn device 6.Vehicle bridge main body 1 is set to below vehicle body and along being laterally extended.One end of swing arm 2 and 1 pivot of vehicle bridge main body
It connects, the other end is for connecting wheel hub.Damper 3 is along being vertically set on swing arm 2 and be connected with vehicle body.Torsion-bar spring 4 can turn
It is set on vehicle body it dynamicly along being laterally extended.Link mechanism 5 be not only connected with swing arm 2 but also with the first end of torsion-bar spring 4
41 are connected.Limit turns device 6 and is connected on vehicle body and with the second end of torsion-bar spring 4 42, can allow the second of torsion-bar spring 4
End 42 prevents the second end 42 of torsion-bar spring 4 from continuing after rotating a predetermined angle.Wherein, when wheel hub pushes swing arm
2 when swinging upward or downward relative to vehicle bridge main body 1, link mechanism 5 will be driven under the action of swing arm 2 torsion-bar spring 4 around
Own axes rotate, and the second end 42 of torsion-bar spring 4 stops after capable of rotating a predetermined angle under the action of limit turns device 6 at this time
Only, and the first end 41 of torsion-bar spring 4 can its second end 42 stopping after persistently rotating and force torsion-bar spring 4 produce
Raw flexible deformation, and then auxiliary damper 3 carries out damping to vehicle body.

Under the action of driving torsion-bar spring 4 rotated around own axes.If automobile in heavy duty or in the case of bear excessive road shocks,
The second end 42 of torsion-bar spring 4 stops after capable of rotating a predetermined angle under the action of limit turns device 6, and the of torsion-bar spring
One end 41 but can persistently rotate after the stopping of its second end and torsion-bar spring 4 is forced to generate flexible deformation, and then assist
Damper 3 carries out damping to carrying out vehicle body, ensure that the ride comfort of automobile, meanwhile, in the common work of torsion-bar spring 4 and damper 3
Under, the rigidity of entire draft hitch is larger so that automobile has good control stability；If automobile is the case where being lightly loaded
Under, the rotation angle of the second end 42 of torsion-bar spring 4 will be less than predetermined angle so that torsion-bar spring 4 cannot be reversed and occur
Elastic deformation, only only damper 3 plays the role of bumper and absorbing shock, and the rigidity of entire draft hitch is smaller, and ensures automobile
Ride comfort in driving process.In conclusion effect of the draft hitch of the utility model in 4 auxiliary damper 3 of torsion-bar spring
Under achieved the effect that change draft hitch rigidity, to ensure that ride comfort of the automobile under different loads, while keeping away again
The variable stiffness coil spring using higher price is exempted from, the manufacturing cost of draft hitch is greatly saved.
Fig. 3 is that the solid of the restricted bearing for turning device for the limit of automotive suspension apparatus of the embodiments of the present invention is shown
It is intended to, Fig. 4 is that the plane of the restricted bearing for turning device for the limit of automotive suspension apparatus of the embodiments of the present invention is shown
It is intended to.As shown in Figure 3 and Figure 4, limit turn device 6 include be set to vehicle body on first bearing seat 61 and restricted bearing 62, it is restricted
Bearing 62 is set in inner ring 621 in torsion-bar spring 4 including anti-rotation and set between inner ring 621 and first bearing seat 61 and not
Energy is relative to the outer ring 622 that first bearing seat 61 rotates, wherein the groove 622a circumferentially extended is equipped on outer ring 622,
Inner ring 621 is equipped with the raised 621a for being inserted into groove 622a so that mating reaction of the inner ring 621 in raised 621a and groove 622a
Under only can relative to outer ring 622 rotate a predetermined angle.It refers to inner ring 621 to be arranged in torsion-bar spring 4 to 621 anti-rotation of inner ring
Always it rotates synchronously, such as can be realized by modes such as interference fit, spline connection or key connections with torsion-bar spring 4.Pass through
Such structure design can effectively simply limit the rotational angle of the second end 42 of spring torsion bar, meanwhile, and to the greatest extent may be used
The difficulty of processing for avoiding increasing to energy restricted bearing 62, to avoid increasing the manufacturing cost of draft hitch.Preferably,
It is seen along the axis direction of restricted bearing 6, raised 621a and the groove 622a close observations on restricted bearing 6 simultaneously
The side of person or the side of separate observer.It can ensure the structural strength of restricted bearing 62 as far as possible in this way, especially
Ensure the structural strength of outer ring 622.
As shown in figure 4, the value range of predetermined angle is -50 °~20 °.The one side wall that ∠ c in Fig. 4 are protrusion 621a
And the angle on groove 622a between the one side wall opposite with protrusion 621a, when protrusion 621a is towards close to the side of the side wall
To when movement, the value of predetermined angle be just, when the protrusion is directed away from the direction movement of the side wall, the value of predetermined angle
It is negative.With the difference of the load condition of automobile, it is adapted to the rigidity of the optimal draft hitch of automobile current load also phase
Difference is answered, only all ensures that the rigidity of draft hitch is in optimal range under different load, can ensure vapour
Vehicle has good ride comfort and control stability always.Inventor is in the structure, load and movement rule for having considered automobile
The many factors such as rule, find after largely testing and putting into practice, for the draft hitch of the utility model, when pre-
If angle ∠ c are above-mentioned value, the rigidity of entire draft hitch is under the underloading of automobile and case of heavy load all in appropriate
In range so that automobile has good ride comfort and operational stability always.Certainly, those skilled in the art can also basis
The situation of automobile reality adjusts above-mentioned predetermined angle, without being confined to this.
