DESCRIPTION

Air spring systems are designed to maximize safe load carrying capacity, stability, and overall ride quality. They are designed and assembled in the USA. Ride-Rite air springs use the same Firestone technology used on many heavy duty trucks, trailers, and buses on the road today. That means you’ll get Firestone’s reputation for commercial grade durability, quality, reliability, and service.

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 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 current market of buses have suspension system consisting of either mechanical or air suspension system. Compared to its counterpart, air suspension system has significant benefits. Vehicle height can be maintained at a particular value irrespective of its load by varying the pressure. Standard coaches also have a system called ferry lift. This allows the air suspension to be raised above the normal ride height level to aid loading and unloading the coach on and off ferries due to their steep ramps and risk of grounding out, but can also be used on rough ground or on steep crests. Although the ferry lift may be installed on some buses, the Kneel Down facility is more common on public transport buses. This helps reduce the step height for easy ingress of passengers. The Kneel Down facility is also used when using the built-in wheelchair ramps.
