DESCRIPTION

Air suspension increases the transport capabilities of trucks and trailers by providing a better grip that levels the entire suspension. An air suspension system can also be adjusted for feel, so drivers can choose between a softer feel for highway cruising or a harder ride for improved handling on more demanding roads.

In the case of hauling heavy loads, air suspension offers more consistency and keeps all wheels even. The air suspension system keeps trucks level from side to side, especially in cases where cargo is difficult to level. This results in reduced body roll when turning corners and curves.

Some of the drawbacks of air suspension systems are because of some of the mechanical issues they can be vulnerable to. Several of the common issues with air suspension systems that can require repair include:

• Rust or moisture damage from the inside that can lead to the air struts or bags to malfunction
• Failure of the air suspension tubing connecting the air struts or bags to the air system
• Air fitting failure resulting from initial fitting or infrequent use
• Compressor burn out due to air leaks in the springs or air struts from the compressor constantly engaging to maintain the proper air pressure

To be succinct, what we have here is a matter of “if it ain’t broke, don’t fix it.” Bus companies don’t see any significant benefit to air springs and air suspension as a whole. Installation of air suspension requires major work and is a very costly undertaking. Spending for aftermarket air springs will be nothing but a money drain. Even for those who are interested in the technology, instead of upgrading the springs of old buses, they can just wait until they need to purchase new units with air springs right out of the factory.
