Air springs for trailer / semitrailer applications

  • Air suspension on trailers ensures gentler treatment of both the load being hauled and any trailer body mounted equipment.

    Trailer air springs further contribute to less road wear due to low natural frequency, reduced unsprung axle mass and reduced wheel load fluctuations. 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. Usually convoluted air springs are used for raising and lowering lift axles.
