Detailed description of the invention
Defer to technique scheme, as depicted in figs. 1 and 2, a resuspended suspension mechanism of a kind of torsion spring and spring assembly damping, comprise cantilever 8, caterpillar wheel 2 is arranged on one end of cantilever 8 by wheel shaft 1, and the other end of cantilever 8 is provided with torsion spring 10; Cantilever 8 is also provided with spring damper.
The hitch of this programme, its agent structure comprises cantilever 8, torsion spring 10 and spring damper.Wherein cantilever 8 is as tie mechanism, carries the effect of installing caterpillar wheel 2, linking springs bumper and torsion spring 10.In use, caterpillar wheel 2 is arranged on the upper end of cantilever 8 by wheel shaft 1, due to cantilever 8 having torsion spring 10 and spring damper, these two structures are all installed on car body, like this when caterpillar wheel 2 shakes, shaking force passes to torsion spring 10 and spring damper by wheel shaft 1, and spring damper energy absorption portion shakes, thus plays cushioning effect; When the vibrations of wheel shaft 1 impel cantilever 8 to rotate, due to rotation, the reset response of torsion spring 10, effective counteracting is carried out for this part shaking force, made the damping effect of spring damper better.
As shown in Figure 1, particularly, wheel shaft 1 is vertically cemented in the side of cantilever 8 upper end, and another side of cantilever 8 upper end is provided with installation shaft 7 with wheel shaft 1 coaxial inner conductor, and described spring damper is installed in installation shaft 7.
Arrange because wheel shaft 1 is parallel to car body place plane, when thus vibrations occur, amplitude maximum is wheel shaft 1.In order to reach better damping effect, spring damper and wheel shaft 1 are coaxially installed, such spring damper can have best damping effect.
The structure of a kind of spring damper proposed in this programme, as shown in Figure 1, spring damper comprises sleeve 6, recoil spring 4 is equipped with in sleeve 6, installation shaft 7 is set with axle sleeve, axle sleeve is fixed with decoupling rod 5, the end of decoupling rod 5 to be stretched in sleeve 6 and is connected with recoil spring 4; Sleeve 6 is provided with limit base 3, and limit base 3 is fixed on car body when mounted.
When shake produce time, vibrations pass to the recoil spring 4 sleeve 6 successively from caterpillar wheel 2, wheel shaft 1, axle sleeve, decoupling rod 5, recoil spring 4 fast by compress energy storage, and is slowly replied, and plays cushioning effect thus.
The bottom of cantilever 8 is provided with installation sleeve 9, cantilever 8 can and installation sleeve 9 between relative sliding; One end of described torsion spring 10 is fixed on installation sleeve 9, and the other end of torsion spring 10 is provided with permanent seat 11, and permanent seat 11 is fixed on car body.
Caterpillar wheel 2 is movable being arranged on wheel shaft 1, if Uneven road makes caterpillar wheel 2 shake, under the effect of wheel shaft 1 and spring damper, time as larger in amplitude of vibration, cantilever 8 will be impelled to rotate.When cantilever 8 rotates, due to can relative sliding between cantilever 8 and installation sleeve 9, thus the dynamics rotated will pass to torsion spring 10, torsion spring 10 rotates, rotation dynamics is absorbed, subsequently under the effect of its elastic-restoring force, slowly restores to the original state, make installation sleeve 9 get back to the original relative position with cantilever 8 simultaneously, complete shock absorbing process.
Consider to understand that the middle part of cantilever 8 is with bending in this programme in order to make damping effect better, and the two ends of cantilever 8 are parallel to each other, as shown in Figure 1, this setup can make decoupling rod 5 vertical with wheel shaft 1, and the length direction of torsion spring 10 is parallel with wheel shaft 1 simultaneously, is conducive to damping.
As shown in Figure 2, the schematic diagram on crawler vehicle is applied in for the utility model.According to the position of caterpillar wheel 2, for convenience of installing, car body plane (horizontal surface) angle of cantilever 8 and installation caterpillar wheel 2 can change between 15 ° ~ 45 °.
