The air suspension will have a variety of states. 1. Stay in shape. When the vehicle is lifted off the ground by the lifter, the air suspension system closes the relevant solenoid valve and the computer remembers the vehicle's height so that it stays the same after landing: 2. Normal state, that is, the engine running state. During the driving process, if the vehicle height changes beyond a certain range, the air suspension system will adjust the vehicle height every once in a while: 3. Wake up state. When the air suspension system is awakened by a remote key, door switch or trunk lid switch, the system checks the height of the vehicle through the body height sensor. If the height of the car falls below a certain height, the tank will provide pressure to lift the car to normal height. At the same time, the air suspension can adjust the softness of the shock absorber, including soft, normal, hard state (also marked as comfortable, normal, movement, etc.), and the driver can control it through the control button in the car.
Of course, compared with the traditional suspension, due to the complex structure of the air adjustable suspension, the probability and frequency of failure will be higher than the spiral spring suspension system, and the air is used as the power source to adjust the height. Sealing of chassis, related components is also an issue. In addition, if the chassis height is frequently adjusted, it may cause local overheating of the pump system and greatly shorten the service life of the pump. Of course, with the continuous improvement of the technical level, many problems have been well solved, and the models used are more and more extensive.
