Air suspension is a kind of suspension with outstanding advantages and disadvantages.
In fact, air suspension is not as simple as an air spring, it also requires the cooperation of CDC (adjustable damping damper). With the cooperation of the two, in addition to being lighter (really there is air), the suspension can also be adjusted in height and softness and rigidity.
For example, when you are driving at a high speed, you can adjust the suspension down and hard to improve the stability and handling of the body; when passing through bumpy roads, you can adjust it up and down to obtain a better shock absorption effect.
Because the air suspension is light, and it also takes into account the hardness and height, it is also widely used in commercial vehicles, such as pickups, medium and large passenger cars, and trucks. So don't say in the future that you haven't been in an air-suspended car.
However, the air suspension will not dominate the beams on these models. It needs to be used in conjunction with the traditional suspension structure to achieve the best results (such as leaf springs). Because the damping effect is good, the latest GB1589 (national standard) also specifically pointed out that models with air suspension can still pull an extra ton of cargo, which is a special reward for it.
In summary, the air suspension has the advantages of light weight, adjustable height and soft and hard. But this does not mean that the air suspension is perfect. Judging from the characteristics of the air suspension, it will inevitably test the wear resistance of components such as joints and rubber membranes, and the exposed rubber is inherently susceptible to environmental effects and aging
