What's the difference between air suspension and traditional suspension? What types of automobile suspensions are there?

Compared with the traditional steel automobile suspension system, air suspension has many advantages, the most important point is the elastic coefficient of the spring, that is, the soft and hard performance of the spring can be automatically adjusted according to needs. For example, when driving at high speed, the suspension can be hardened to improve the stability of the car body. When driving at a low speed for a long time, the control unit will think that it is passing through a bumpy road, and the suspension will soften, improving the shock absorption comfort. Independent suspension system At present, most cars are independent suspension systems. According to different structural forms, independent suspension systems can be divided into cross-arm, longitudinal-arm, multi-link, candle and McPherson suspension systems. Non-independent suspension system The structural feature of non-independent suspension system is that the wheels on both sides are connected by an integral frame, and the wheels and axles are suspended under the frame or car body through an elastic suspension system. Non-independent suspension system has the advantages of simple structure, low cost, high strength, easy maintenance and little change in front wheel alignment during driving. However, due to its poor comfort and handling stability, it is also used in modern cars, basically used in the rear suspension of small cars and compact cars, and also used in trucks and buses.
