What does car air suspension mean?

[Kieran]

The suspension system refers to all the force-transmitting connection devices between the car frame and the axle or wheels. Its function is to transmit forces and torques acting between the wheels and the frame, buffer the impact force transmitted from uneven road surfaces to the frame or body, and dampen the resulting vibrations to ensure smooth driving. The following is relevant content introduction: 1. The working principle of air suspension is to use an air compressor to form compressed air and deliver it to the air chambers of the springs and shock absorbers, thereby changing the vehicle's height. Level height sensors are installed near the front and rear wheels. Based on the output signals from these sensors, the air suspension control unit determines changes in vehicle height and then controls the compressor and exhaust valve to compress or extend the springs, achieving shock absorption. 2. Current air suspension systems typically use small electric motors or the engine to drive the air compressor to pre-compress air into the storage tank, eliminating the need for compression time when suspension adjustment is required.
