The application of automobile air suspension system in China lags behind foreign countries for several decades. Until recent years, with the introduction of high-end bus manufacturing technology and the improvement of people's requirements for comfort, coupled with the national standard requirements for bus grade division, the automobile air suspension system began to be gradually applied. At present, the air suspension is mainly applied in the high class bus, but restricted by many factors, the allocation rate of the automobile air suspension system is still very low, basically still belongs to the "import" stage. Why don't low-end cars have automotive air suspension?
On the one hand, because of the expensive price, although the system is good, but each set of prices are much more expensive than ordinary suspension, after-sales maintenance costs are also higher. On the other hand, the air suspension determines that the car can not be overloaded, which is a common overload of domestic trucks also limited its development. Therefore, it can not be seen in ordinary cars, but in some super sports cars and SUVs.
