Air Suspension
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, in order to increase the stability of car body through sexual or complex road conditions.
In the daily regulation, air suspension there will be some state. 1, keep fit. Lifter when the vehicle is raised, away from the ground, the air suspension system will close the related electromagnetic valve, computer memory body height at the same time, keep the vehicle after landing the original height: 2, normal state, the state of engine operation. Driving process, if the body height change over a certain range, the air suspension system adjust every once in a while the body height: 3, wake up. When the air suspension system are remote control key, the door switch or luggage compartment cover switch after wake up, the system will be through the body level sensor check body height. If the body height is lower than the normal height to a certain extent, air tank will provide pressure make the body to normal height. At the same time, the air suspension can adjust damper hardness, including soft state, normal and hard state three state (also have marked as comfortable, ordinary, sports three patterns, etc.), the driver can be controlled through the car's control button.
Compared with traditional suspension, of course, due to the air type adjustable suspension structure is relatively complex, the failure probability and frequency will be higher than that of helical spring suspension system, and USES air as power source of adjust the ride height, sealing is also a problem of related parts, in addition, if frequently adjust the ride height, and may cause local overheating pump system, can greatly shorten the service life of pump. Of course, with the continuous improvement of technical level, a lot of problems have been good, at the same time, the application of the model is becoming more and more widely.
