(Summary description)The air suspension is structurally consistent with the traditional suspension, and is also composed of two major components, a spring and a shock absorber. The difference is that the air suspension spring is equipped with high-pressure air, and the softness and hardness of the spring can be changed according to different needs; the damping of the shock absorber is not static, and it is also adjustable. In other words, the biggest difference between air suspension and traditional suspension is that the characteristics of the suspension are variable, such as height, softness and hardness, etc. can be adjusted according to different road surfaces. So the user has a lot of choice in the suspension characteristics setting. Models equipped with air suspension are mostly set to automatic, comfortable, normal and sports modes. Users can choose different modes according to the road conditions and their preferences. In automatic mode, the on-board computer will adjust the height of the chassis and the softness of the suspension according to the vehicle speed and various dynamic parameters of the body. For example, the chassis will automatically lower at high speeds, and the suspension will become hard during intense driving. Of course, the computer calculates Not necessarily accurate, and the response is not necessarily very positive, so there are several other modes of choice. When the comfort mode is selected, the chassis will be adjusted to the highest level and the suspension will become the softest. This mode is more suitable for driving on potholes and greatly improves driving comfort. If you drive violently at this time, the vehicle will shake more severely and the limit will be relatively low. In the normal mode, the height of the chassis and the hardness of the suspension are in the middle level, which is suitable for good pavement. In the sport mode, the chassis is adjusted to the lowest and the suspension becomes the hardest, suitable for intense driving, and the comfort is inferior to the previous two modes. From our experience, in addition to the sports mode, the chassis height can be manually adjusted in other modes to improve the passing of the vehicle, which is very user-friendly. The emergence of air suspension gives a car multiple personalities and greatly improves road adaptability. It is an equipment that is beneficial to the car. As the air suspension technology is more sophisticated, the cost is high, and the maintenance cost is relatively expensive. Most of the air suspension is equipped on luxury cars, such as Mercedes-Benz S-class, Porsche Cayenne, Audi Q7, etc., but with the popularity of technology and cost Decrease, the current equipment has a downward trend, and the current minimum has been "decentralized" to some luxury brand models of around 500,000 yuan.
