About Air Suspension Air suspension system, mainly composed of air spring and shock absorbers barrel core, it and the traditional mechanical suspension is different lies in the support of the vehicle spring. In the air suspension assembly, the spring is an air spring, while the traditional suspension is a regular spring. The former can adjust the hardness and height of the air spring according to the state of the road through the car computer. Advantages 1, improve the ride comfort of the vehicle;
2, improve the stability of vehicle driving control;
3, enhance the vehicle driving power and braking force on bumpy road;
4, the body height remains the same, will not increase or decrease with the load, reduce or increase;
5, prolong the service life of tires and brake discs;
6, reduce electrical, air conditioning, exhaust system, bridge, body and chassis maintenance costs;
7, prolong the service life of the vehicle and increase the depreciation value.
Its biggest advantage is that it can not only increase the stability of high-speed body or the passability of complex road conditions, improve the ride comfort of passengers, but also play an important role in road protection.
Generally speaking, equipment type adjustable air suspension vehicle front and rear wheels will be equipped with distance from the ground near the sensor, according to the distance from the earth sensor output signal, the driving computer can judge the body height change, to control the air compressor and the exhaust valve, make the spring automatic compression or elongation, so as to reduce or increase the chassis ground clearance, Increase the stability of high-speed body or the passability of complex road conditions.
