OEM NUMBER

DESCRIPTION

Air suspension on trailers/semi-trailers ensures not only gentler treatment of the load being hauled but also less wear and tear on the roads. This aspect is of growing importance as traffic volume becomes increasing dense. As a rule, each axle has two air springs. In multi-axle combinations, one axle is frequently provided with an axle-lifting device to protect the tires on empty runs or when the vehicle is only partially loaded. Convoluted air springs usually are used for raising and lowering lift axles.

Air springs have been used in heavy duty vehicle suspension systems for nearly a century, where they have been able to provide usefulness by taking advantage of the compressed air required for vehicle braking systems. Air springs have provided a two-fold advantage over mechanical leaf- or coil-springs. One advantage with air suspension is the extra comfort provided by being able to vary the air pressure inside the spring, which changes the spring rate, and therefore, ride quality. Additionally, because variable control over air pressure adjusts the deck or trailer height, aligning loading docks to the level of the deck is possible when dock plates are unavailable.

For coil-sprung vehicles, the air springs fit directly into the coil spring, then are expanded by adding air pressure to support the coils and prevent them from completely compressing, creating a smoother ride and restoring any ride height lost when a heavy load is applied.

Installation is fast and simple and most of our applications do not require you to drill into your vehicle’s frame.
