Air suspension is a common function to adjust vehicle height. When the vehicle body needs to pass through, the high-pressure gas in the air tank is filled into the air spring, which makes the volume of the air spring larger and increases the height of the vehicle. Stability is usually required at high speeds. At this time, we need to reduce the height of the car body, and the air in the air spring is directly discharged into the atmosphere through the solenoid valve.
The air suspension can be adjusted automatically or manually. The height changes described above can be adjusted manually. When driving on more complex roads, automatic adjustment can be selected. For example, in the case of high-speed bending, in order to avoid severe roll, the air spring and shock absorber of the outer wheel will automatically harden to reduce the body roll. Of course, in the case of emergency braking, the air springs of the two front wheels and the hardness of the shock absorbers have also been adjusted to reduce the phenomenon of brake tilting forward.
