The advantages and disadvantages of air suspension are as follows. First, the advantage of air suspension is that it can adjust the high and low state of vehicle suspension at any time according to the road conditions of the vehicle, thus ensuring the comfort of drivers and passengers in the vehicle. Improve the overall driving maneuverability and passability of the vehicle. Secondly, in the process of high-speed driving, the high-speed suspension system can automatically adjust the soft and hard state of the vehicle suspension according to the relevant acceleration, sensors and the horizontal position of the vehicle, thus improving the driving comfort and maneuverability of the vehicle when driving at high speed. Thirdly, the disadvantage of air suspension is that the manufacturing cost is relatively high, and it is easy to have corresponding faults after a long time, and the related parts are easy to age. Fourth, the air is suspended for a long time, which is easy to leak or the related solenoid valve has problems. Once the air leakage is serious, it will cause air to hang and stay. If it is particularly serious, the vehicle cannot run normally. And relatively speaking, the maintenance cost of air suspension system components is very high. The price of a normal air suspension airbag assembly is about 10000 to 15000. Air suspension refers to the use of rubber airbags instead of springs. Strictly speaking, it should be called air spring. This part has nothing to do with suspension parts, but belongs to the replacement of springs.
