Abstract

An air suspension system, includes an air suspension bellows connected to a vehicle frame, and an air suspension piston connected to a link, wherein the air suspension bellows and the air suspension piston are connected to each other and enclose an inner air volume, the air suspension piston has a rolling surface for rolling of the air suspension bellows, the air suspension bellows has a contact portion for rolling on the rolling surface, the rolling surface or the contact portion has at least one opening, wherein contacting areas of the rolling surface and the contact portion define a contact surface, and wherein a fluidic connection for an air flow through the at least one opening between the inner air volume and an environment is enabled and prevented by a change in the contact surface that includes a relative movement of the air suspension bellows to the air suspension piston.
