List of reference symbols:

1. a wheel; 2. an axle; 3. an air bladder; 4. a gas storage tank; 5. a cylinder; 6. a slidable rod; 7. a roller; 8. a track; 9. a strong spring; 10. a stopper; 11. a drive motor; 12. a U-shaped anti-roll bar; 13. a shock absorber.

Detailed Description

As shown in fig. 1, the combined air suspension device provided by the present invention is mainly divided into three parts: an air bag system with an air bag 3, a shock absorption system with a shock absorber 13 and a roll compensation system with a U-shaped anti-roll bar 12. As is known from the drawing, the shock absorber 13, the air bladder 3 and the air cylinder 5, the slidable rod 6 and the rail 8 below the air bladder 3 are all symmetrically disposed with respect to the air tank 4, and the number is at least 2. In other embodiments, the dampers 13 may be arranged side by side, in a number exceeding 2. The same is true for the air bladder 3. Multiple shock absorbers 13 and multiple air bags 3 provide greater stability for the vehicle, but the cost increases accordingly, and space issues and arrangements on the vehicle chassis should be considered. The cylinder 5 below the air bag 3 is similar in principle to the shock absorber 13, providing height adjustment for the vehicle and support for the air bag 3 by reciprocating the piston and telescopic rod within the cylinder 5. And point-to-point support is easy to cause problems, so that a rod support is added below the air airbag 3, the rod is a slidable rod 6, a roller 7 is arranged at one end of the slidable rod 6, which is in contact with the axle 2, and the roller 7 displaces in a track 8 arranged on the axle 2 to drive the air airbag 3 to change in height. Since the height of the air bag 3 cannot be changed too quickly, the ride comfort of the vehicle is reduced. The roller 7 cannot be too flexible, so that a strong spring 9 is arranged between the rail 8 and the roller 7, so that the movement of the roller 7 is controllable within a certain elastic range.

In an embodiment of the invention, a shock absorber 13 is also provided, the auxiliary air bag 3 providing height adjustment for the vehicle together. Another purpose of providing the shock absorber 13 is that when the air bag 3 goes wrong, the shock absorber 13 can still independently provide shock absorption for the vehicle, thereby ensuring the safety of the vehicle in the driving process and improving the stability.

In the embodiment of the present invention, the inclination of vehicle roll can be reduced when the vehicle is over-bent by the U-shaped anti-roll bar 12 on the axle. When the vehicle body only moves in the vertical direction, the suspensions on both sides deform the same, and the stabilizer bar does not function. When the vehicle body rolls, the suspensions on the two sides jump inconsistently, the transverse U-shaped anti-roll rod 12 twists, and the elastic force of the rod body becomes the resistance for continuing to roll, so that the transverse stabilizing effect is achieved.

The utility model provides a combination formula air suspension device is a plurality of device combinations, and every device complements each other, provides security, stability and travelling comfort for the vehicle.

It should be noted that the above only illustrates the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and a person skilled in the art can make several improvements and decorations without departing from the principle of the present invention, and these improvements and decorations all fall within the protection scope of the claims of the present invention.
