Claim Text:
1. An air spring for running gear assemblies of vehicles, which is clamped with an air spring piston and an air spring cover between the running gear assembly and a vehicle body of a motor vehicle, comprising: an air spring bellows made from elastomeric material, which at least partially delimits a compressed air-filled working chamber and which, forming at least one rolling fold, rolls on the air spring piston, wherein the air spring bellows is attached by clamping elements at a first end to the air spring cover and at a second end to the air spring piston, and an external guide, which is attached to the air spring bellows and spaced apart from the air spring cover and which is attached to the air spring bellows in such a way that a partial piece of the air spring bellows between the air spring cover and the external guide is formed as a cardanic fold which permits a deflection of the air spring bellows produced by forces acting perpendicular to the axis of the air spring bellows, wherein the air spring bellows has a folded-over ply at the first end, said folded-over ply being folded back over such a length that, after assembly of the air spring, the folded-over ply partially covers the external guide with an overlap, wherein the external guide is attached to the air spring bellows in the region of the overlap of the folded-over ply by an external clamping element such that, at a portion of the external guide that overlaps with the external clamping element in a radial direction of the air spring bellows, an outer surface of the external guide contacts the folded-over ply and an inner surface of the external guide contacts the air spring bellows.
