Problems solved by technology

[0002] In foreign countries, the air suspension system is more than 80% used on heavy trucks, and 100% used on high-speed buses and luxury city buses. Some cars are also equipped with this system. It elastically connects the frame with the wheels. Its main task is to transmit all the forces and moments acting between the wheels and the frame, and buffer the impact force transmitted to the frame from the uneven road surface, and reduce the vibration caused by it, so as to ensure that the car can run smoothly; in fact , the basic principle of the air suspension device can be applied to all walking devices, but compared with automobiles, the structure of the air suspension device for automobiles is too complicated and complete, the portability is very low, and the cost is also high. In addition , since the suspension device is driven by air, and the air volume is used as input, the traditional way to improve the performance of the device is to improve the performance of the air pump, which naturally requires a lot of cost. Therefore, it is necessary to design a simple structure, low cost and a A new structure to improve performance makes sense

Abstract

The invention relates to the field of auxiliary equipment for transportation devices, and specifically discloses an air suspension device, including a vehicle body, a wheel frame device is arranged under the vehicle body, and the wheel frame device includes a first lug plate, and the bottom of the first lug plate is A first telescopic rod is provided, a second ear plate is provided under the vehicle body, a third ear plate is provided under the vehicle body, a second connecting rod is provided under the second ear plate, and a second connecting rod is provided under the third ear plate. A first connecting rod is provided, and the length of the first connecting rod is the same as that of the second connecting rod and is arranged in parallel; an air pump is arranged at the center of the bottom of the vehicle body, and the first telescopic rod and the second telescopic rod both include a first barrel. The present invention realizes the function of distance enlargement through the cooperation of gears with the first rack and the second rack, which greatly improves the performance of the device, and adjusts the height of the wheel through the principle of parallelogram. In addition, the present invention also provides two fixed points, which is convenient for secondary Development, the device structure is simple, and the cost is extremely low.
