DESCRIPTION

When you start talking about air suspensions, the basic idea isn't all that hard to grasp. As the name suggests, instead of metal coils or leaf springs, an air suspension system uses air springs. And since the air needs to be contained somehow, the air springs look more like rubber balloons than springs.

But beyond that, what's the purpose? How does it work? What advantages are there to an air suspension? And why do you see them used in everything from pickup trucks to luxury cars and highly modified low riders?

Our friends at engineering gets into all of that, explaining the different types of air springs, the different types of air suspension systems, and the pros and cons of using on on a car. If you've ever had a question about air suspensions, odds are, he answers it here.

Air bag or air strut failure is usually caused by wet rust, due to old age, or moisture within the air system that damages it from the inside. Air ride suspension parts may fail because rubber dries out. Punctures to the air bag may be caused from on the road. With custom applications, improper installation may cause the air bags to rub against the vehicle's frame or other surrounding parts, damaging it. The over-extension of an air spring which is not sufficiently constrained by other suspension components, such as a shock absorber, may also lead to the premature failure of an air spring through the tearing of the flexible layers. Failure of an air spring may also result in complete immobilization of the vehicle, since the vehicle will rub against the ground or be too high to move. However, most modern automotive systems have overcome many of these problems.

The air springs were designed to provide a smooth ride, with the additional ability to raise the body of the vehicle for off-road clearance and lower it for higher-speeds road driving. Mechanical springs, for which deflection is proportional to load, cannot do this; with ECAS height is largely independent of load. The developers of ECAS also designed LoadSafe, a related system to ascertain load and change in load on an LCV type vehicle fitted with air springs.
