Abstract:
1. A pneumatic bellows for a pneumatic suspension, comprising: an axle-sided area of the pneumatic bellows has a preshaped adapted shape when in its basic state, such that the axle-sided area is arrangeable on a protrusion of a plunger, wherein a protrusion of a plunger has a given shape and the adapted shape of the axle-sided area is substantially complementary to the given shape of protrusion of the plunger when no external force is exerted on the pneumatic bellows; and wherein the axle-sided area assumes the adapted shape as the axle-sided area is moved towards a frame-sided area of the pneumatic bellows after essentially complete extension of the pneumatic bellows from a shape that is different than the adapted shape, and wherein the adapted shape of the axle-sided area is designed such that the adapted shape of the pneumatic bellows rolls over the plunger in a movement of the axle-sided area toward the frame-sided area.
