Whether the structural form and performance parameters of American air suspension are reasonable or not, the suspension system is one of the important assemblies in modern vehicles. It directly has a great impact on the driving smoothness, handling stability and comfort of vehicles. I know that the controllability and comfort of a car are two criteria for considering the performance of a car, and it is difficult to take both into account: the soft suspension can enhance the ride comfort because it filters a lot of impacts from the road, but the controllability will be greatly reduced; The harder suspension improves the vehicle's handling performance, but it will lead to a decline in ride comfort. So I can see that the suspension of ordinary sports cars is generally adjusted hard, while that of comfortable cars is the opposite. In the face of the fact that we can't have it both ways, greedy people do not compromise. The development of science and technology has solved this "soft and hard" problem. If the damping of the suspension can be artificially changed, the driver can set the characteristics of the suspension according to his own preferences, which is undoubtedly a big temptation for the driver. The air suspension completes this task.
In terms of American air suspension safety, active air suspension has unique charm not only in terms of comfort. Due to the involvement of the electronic system, the limit control capability of the active suspension is better than that of the ordinary suspension: when cornering at high speed, the trip computer controls the air springs and shock absorbers of the outer wheels to automatically harden, so as to reduce the body roll; During emergency braking, the electronic module will also strengthen the spring and shock absorber stiffness of the front wheels to reduce the inertial forward tilt of the body. The American air suspension also integrates the traditional chassis lifting technology: when the car runs at high speed, the body height will automatically reduce, thus improving the ground contact performance to ensure good high-speed driving stability; When the vehicle needs to pass through the bumpy road slowly, the chassis can automatically rise to improve the passing performance. Active air suspension can really be described as soft and hard. Conclusion: Control the inflation amount of the air spring airbag through the selection of the car computer and driver mode, and then control the height and damping of the body.
