空氣懸掛也并不是近幾年才研發(fā)的新技術，它們的基本技術方案相似，主要包括內部裝有壓縮空氣的空氣彈簧和阻尼可變的減震器兩部分。
與傳統(tǒng)鋼制懸掛想比較，空氣懸掛具有很多優(yōu)勢，重要的一點是彈簧的彈性系數(shù)也是彈簧的軟硬能根據(jù)需要自動調節(jié)。例如，高速行駛時懸掛可以變硬，以提高車身穩(wěn)定性，長時間低速行駛時，控制單元會認為正在經(jīng)過顛簸路面，以懸掛變軟來提高減震舒適性。
另外，車輪受到地面沖擊產(chǎn)生的加速度也是空氣彈簧自動調節(jié)時考慮的參數(shù)之一。例如高速過彎時，外側車輪的空氣彈簧和減震器會自動變硬，以減小車身的側傾，在緊急制動時電子模塊也會對前輪的彈簧和減震器硬度進行加強以減小車身的慣性前傾。因此，裝有空氣彈簧的車型比其它汽車擁有更高的操控極限和舒適度。
彈簧的彈性系數(shù)是通過橡膠皮腔中空氣的流量來調節(jié)的。在短波路面或高速過彎時，皮腔中的部分氣體會被鎖定，在皮腔受壓時，空氣流量減小，令彈簧變硬，以減小車身起伏和提高車身穩(wěn)定性。在普通路面上，所有空氣都可以自由流動，皮腔受壓時，空氣流量加大，從而提供柔軟的彈簧和大程度的行駛舒適性。空氣懸掛還將傳統(tǒng)的底盤升降技術融入其中。高速行駛時，車身高度自動降低，從而提高貼地性能確保良好的高速行駛穩(wěn)定性同時降低風阻和油耗。慢速通過顛簸路面時，底盤自動升高，以提高通過性能。另外，空氣懸掛系統(tǒng)還能自動保持車身水平高度，無論空載滿載，車身高度都能恒定不變，這樣在任何載荷情況下，懸掛系統(tǒng)的彈簧行程都保持一定，從而使減震特性基本不會受到影響。因此即便是滿載情況下，車身也很容易控制。

Air suspension is not only in recent years research and development of new technologies, their basic technology similar to the scheme, including the internal with the compressed air to the air spring and shock absorber damping variable two part.
Compared with the traditional steel suspension to compare, air suspension has a lot of advantages, the most important point is that the elasticity coefficient of the spring is spring and can automatically adjust according to need. For example, when high speed travel suspension can become hard, in order to improve the stability of the car, long time runs at a low speed, the control unit that is after a bumpy road, to the suspension to improve soft shock absorbing comfort.
In addition, the wheel has ground impact acceleration is the air spring to automatically adjust the parameters of. For example, the high speed turns, the outer wheel of the air spring and shock absorber will automatically become hard, in order to reduce body roll, in emergency braking electronic module will be on the front of the spring and the shock absorber to reduce the hardness of strengthening body 's inertial forward. Therefore, equipped with air spring model than other car has higher control limit and comfort.
Spring elasticity coefficient is through a rubber cavity air traffic regulation. In short the road or high speed turns, leather cavity portion of the gas will be locked in the skin when pressed, cavity, air flow is reduced, so that the spring become hard, in order to reduce the fluctuation and improve the stability of the car body. On common road, all of the air can flow freely, leather chamber pressure, air flow is increased, thereby providing a soft spring and the greatest degree of comfort. Air suspension is traditional lifting technology into one. When running at a high speed, vehicle body height reduced automatically, thereby improving the surface properties to ensure a good high-speed running stability while reducing wind resistance and oil consumption. Slow through the bumps, chassis automatic elevation, in order to improve performance through. In addition, the air suspension system can automatically keep the body level, regardless of no-load full load, the height of the body is constant, so that at no load conditions, suspension spring trip to maintain a certain, so that the shock absorbing characteristics is basically not affected. Thus even under the condition of full load, the body is also very easy to control.
