An air spring unit for a vehicle is described. The air spring unit forms a rolling fold and a cardanic fold. A type of bellows guidance of the air spring, the cardanic fold begins, at the rolling fold side, below that end of the external guide of the air spring unit which is at the air spring cover side. A cardanic fold of axially short construction is realized which, despite a small axial structural space, has the elasticity of a cardanic fold of tall construction.

A suspension device for a wheeled vehicle with a plurality of air springs is described. Two main air chambers of two air springs of a respective vehicle axle are connected together via a transverse air chamber which forms an intermediate volume. A compressor arranged between the two transverse air chambers is connected to the first transverse air chamber via a first connecting line in which a first switchable valve is arranged, and to the second transverse air chamber via a second connecting line in which a second switchable valve is arranged, so that direct filling/direct evacuation of the intermediate volumes of the two transverse air chambers is possible.

A pneumatic spring and damper unit () has working chambers () which are filled with compressed air and are partially defined by rolled bellows or corrugated bellows. The working chambers are superimposed and connected through throttle valves, arranged inside a common pot-shaped cylindrical housing (), and separated by a cylindrical piston (), in such a way that one working chamber () is arranged on the front side of the piston and the other working chamber () is arranged on the rear side of the piston. The piston and the piston rod () are respectively sealed by roller bellows inside the cylindrical housing and guided therein, and the piston rod and the piston are interconnected by an articulation ().

Disclosed is a pneumatic spring shock absorber unit having working chambers (), which are filled with compressed air and which are partially delimited by rolling or folding bellows (). These working chambers are situated one above the other and are interconnected via throttle valves that can be flowed through. Both working chambers are located inside a common pot-shaped housing () and are separated by a piston () so that one working chamber () is located on the front side of the piston and the other working chamber () is located on the rear side of the piston and at least partially surrounds the piston rod () so that the piston and the piston rod are sealed and guided inside the housing by rolling bellows ().

A rolling-lobe air spring () includes a cover (cover plate,-I or-II), a roll-off piston () and a rolling-lobe flexible member (). A support bell (-I or-II) is provided in order to solve stability problems. The support bell (-I or-II) is rigidly connected to the cover (-I or-II) in order to provide a guide of high stiffness to the rolling-lobe flexible member. The support bell (-I or-II) is rigidly connected to the cover (-I or-II) and can be arranged within or outside of the cover (-I or-II). For an inner-lying support bell (-I) the upper end of the rolling-lobe flexible member is attached to the throat region (-I) of the support bell (-I) with the aid of a clamp ring (-I) applied from the outside. For an outside-lying support bell (-II), the throat region (-II) of the support bell (-II) is deformed against the upper end of the rolling-lobe flexible member and against a support ring (-II) disposed therebelow.

An air spring includes a flexible member, which encloses an air volume, and two connecting parts. Each of the connecting parts has a clamp seat on which an end of the flexible member is attached with the aid of a clamp ring assigned to the clamp seat. The surface of at least one clamp seat is at least approximately convex and the total inner side of the clamp ring, which is assigned to the clamp seat, is configured to be at least approximately concave.
