Maximum is reached, due to the supporting role of air spring, the position at the top of square set does not occur violent change.
When rotating shaft and steering wheel are given a shock motion upwards, spacer pin and shaft coupling promote postive stop baffle to transport upwards therewith
Dynamic, air spring inner chamber is extruded and deforms upwards, when the pressure that compressed air is filled in extruding force and air spring inner chamber
When equal, air spring no longer deforms, and due to the supporting role of air spring, the position at the top of square set does not occur
Violent change.
When connection steering mechanism on the steering wheel drives steering wheel and axis of rotation, in the effect of spacing guide pad
Under, postive stop baffle, air spring and square set do not rotate.
The beneficial effects of the utility model are：
（1）The damping device that the utility model is connected as vehicle frame using air spring with steering wheel, in vehicle traveling
During when being given a shock, flexible due to air spring has larger longitudinally adjusted scope, has effectively buffered vehicle frame and has been held
That receives shakes, and damping effect is notable；
（2）The utility model is welded with tangent lock sleeve vertical with the side wall of rotating shaft on the side wall of steering wheel so that
Connection between steering wheel and rotating shaft is more firm；
（3）The utility model sets spacing guide pad in the side of postive stop baffle, to prevent postive stop baffle from following steering wheel
Rotation and rotate；The position of spacing guide pad is fixed by bolt compresses rubber blanket so that spacing guide pad is installed
It is firm；
（4）The utility model compact conformation, small volume will not increase the height of vehicle frame.
