1. Air suspension refers to the suspension with pneumatic shock absorber. Independent suspension can also use pneumatic shock absorber. Most of the air suspension can automatically adjust the height. Independent suspension is not bad. In fact, air suspension is also used. Multi-link independent suspension, but the shock-absorbing spring is replaced by a cylinder type. Pneumatic shock absorbers have the advantages and disadvantages of using the same suspension type compared with ordinary spring shock absorbers;
2. Advantages of pneumatic shock absorbers: the distance from the ground can be adjusted simply by air pressure (the height of the chassis is generally calculated from the middle of the car);
3. Disadvantages: There is a slight leakage, and the air needs to be supplemented frequently.
