Detailed description of the invention
See Fig. 1 and Fig. 2, the utility model provides a kind of trailer with air suspension system, comprises vehicle bridge 3, vehicle frame and shock mitigation system, and the quantity of described vehicle bridge 3 is at least 2, arrange before and after described at least 2 vehicle bridge 3, described vehicle frame is arranged in described vehicle bridge 3 by shock mitigation system.
Described shock mitigation system comprises air suspension system and torsion bar, described air suspension system comprises air bellow group, the quantity of described air bellow group is 2 times of the quantity of described vehicle bridge 3, and the arranged on left and right sides of described vehicle bridge 3 is separately installed with a described air bellow group.
It should be noted that, each air bellow group comprises at least one air bellow 4.
Suppose that air bellow group is an air bellow 4:
Specifically, the left side of each vehicle bridge 3 and right side are all provided with an air bellow 4, and such vehicle bridge 3 is just supported by air bellow 4 pairs of vehicle frames.
And (suppose it is 2) when each air bellow group comprises the air bellow 4 of more than 2, the left side of vehicle bridge 3 is provided with 2 air bellows 4, the right side of vehicle bridge 3 is also provided with 2 air bellows 4, that is, each vehicle bridge 3 is provided with 4 air bellows 4.

The effect of torsion bar:
When left and right wheels passes through identical bump or hole, torsion bar can't produce effect.If but left and right wheels respectively by different bump or hole time, when namely the level height of left and right wheels is different, the torsion of shaft can be caused, produce anti-dumping resistance and suppress vehicle body twisting.That is when the level height synchronization action of the right and left, torsion bar would not be had an effect, only at the right and left vehicle body because torsion bar just generation effect when road surface rises and falls or turned to the curved asynchronous action caused.If will completely by spring reduce vehicle body inclination torsion that may need stone spring, more suppress the spring of spring with the Shock absorber that damping coefficient is very high, so we just must go to bear hard spring and Shock absorber cause the sequelae that when such as passing through uneven road surface, tracking is bad.If but coordinate suitable torsion bar can significantly reduce inclination torsion, therefore, the collocation of torsion bar and air bellow 4 is the most feasible methods reaching cruising characteristic and handling compromise.
Torsion bar and air bellow 4 provide anti-dumping resistance be complementary, and anti-dumping resistance occurs in pairs, that is the anti-dumping resistance on chassis is with occurring with the anti-dumping resistance of vehicle body, but before and after the relation of the effect of vehicle body counterweight ratio and other external force can make, upper and lower anti-dumping resistance overbalance, just directly can affect the transfer of vehicle body load capacity and the balance of manipulation thus.In order to improve vehicle body stationarity, we not only can utilize torsion bar more can be used for controlling the front and back proportional distribution of vehicle body anti-dumping resistance to the twisting controlling vehicle body.The most important function of torsion bar be exactly reach vehicle body balance and limited curved time body roll torsion with improve tire subsides ground property.The vehicle body of the curved interior elongation taken turns when crossing curved and curved foreign steamer is extruded, and at this moment torsion bar will produce to reverse and suppress this situation.It can hang the vehicle body of curved foreign steamer and execute one to the strength pressed down, and executes the strength lifted to the curved interior vehicle body suspension taken turns, and the application force bestowing left and right suspension is that equal and opposite in direction direction pins down on the contrary mutually.The camber angle that too soft torsion bar is too much when the car of Pneumatic Suspension can cause curved, reduces the ground contact area of tire, is then too firmly to cause tire cannot close proximity to ground, affects vehicle body stationarity.
