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.

In buses, air springs deliver safety and ride comfort. Thanks to the self-leveling system, the vehicle maintains the same level, which means that the boarding level also remains unchanged, regardless of the number of passengers. With additional control functions, the vehicle body can “kneel”, which aids entry and alighting. This generally entails fitting two air springs to the front axle and trailing axle and four on the rear or drive axles.

The weight of a truck, and thus the axle load, fluctuates greatly depending on the payload at any given moment. To meet the resulting suspension requirements, virtually all commercial vehicle manufacturers now employ air springs. In providing for level control, air springs also guarantee that the vehicle body maintains a constant road clearance. This, in turn, ensures safe driving regardless of the loading conditions. The vehicle body can also be raised or lowered by means of air springs actuated via optional auxiliary manual controls. This is of advantage in adjusting vehicle body height to the level of a ramp or in placing an interchangeable platform.
