I would like to ask Zhongding Co., Ltd., what are the functions of the air suspension system? What is the proportion of air suspension systems installed in the entire car at present?

Compared with the traditional steel automobile suspension system, air suspension has many advantages. The most important point is that the elastic coefficient of the spring, that is, the hardness of the spring, can be automatically adjusted according to the needs. According to the different road conditions and the signal of the distance sensor, the driving computer will determine the change in the height of the vehicle body, and then control the air compressor and the exhaust valve to automatically compress or extend the spring, thereby reducing or increasing the ground clearance of the chassis to increase the stability of the high-speed vehicle body or the passability of complex road conditions. The air suspension system enables a car to have both the comfort of a sedan and the handling performance of an off-road vehicle. AMK China has obtained orders from many domestic new car-making forces and traditional independent brand leading enterprises. As of now, the total output value of the domestic air suspension business of Zhongding Co., Ltd. is about 12.1 billion yuan, of which the total output value of assembly product orders is about 1.7 billion yuan.
