Front air spring 
Front air spring: The air spring is filled with compressed air in a sealed container, and its elastic effect is realized by the compressibility of the gas. The air spring has ideal nonlinear elastic characteristics. After the height adjusting device is installed, the height of the vehicle body does not change with the increase or decrease of the load, the spring stiffness can be designed to be low, and the riding comfort is good. 
Rear air spring 
Rear air spring: air spring is in a sealed container filled with compressed air, the use of gas compressibility to achieve its elastic effect. The air spring has ideal nonlinear elastic characteristics. After the height adjusting device is installed, the height of the vehicle body does not change with the increase or decrease of the load, the spring stiffness can be designed to be low, and the riding comfort is good.
Controller software and hardware
Controller hardware and software: The controller is an important part of the air suspension system. It is usually used to monitor and control the air pressure and working state of the air spring. 
Air Supply Unit Assembly (ASU) 
Air Supply Unit Assembly (ASU): The air supply unit assembly provides clean, dry compressed air for the air suspension system 
FIO
FIO: Integrated air supply unit assembly (FIO) for closed systems to achieve a high degree of integration of air compressor, distribution valve, sub-controller and air reservoir; 
Active stabilizer bar 
Active stabilizer bar: The active stabilizer bar (IARC) replaces the passive stabilizer bar for variable stiffness and active adjustment to improve vehicle handling. 

Case presentation

Double chamber air spring:

1. At each height, the active selection of high and low stiffness is realized by switching between small chamber mode and large chamber mode.

2. Design offset frequency switching range: about 1.00-1.20Hz at front, 1.10-1.32Hz at rear.

3. The two modes show more performance orientation of ride comfort or handling stability.

Multi-chamber air spring:

1. At each height, the active selection of four stiffness modes is realized by different combinations of the three chambers.

2. The four combination modes are as follows from low to high by rigidity: V1+V2+V3, V1+V2, V1+V3, and V1.

3. Design offset frequency switching range: about 1.00-1.20Hz at front, 1.10-1.32Hz at rear.
