Rolling-lobe air spring with bell-shaped support

The supporting bell (16-1) is rigidly joined to the air spring lid (6-1), preferably in one piece and is seen to lie inside the bellows (4) and here extend over the upper part (as seen) of the bellows to its maximum diameter. This inside bell clamps the bellows top end by a clamping ring (12-1) at the bell neck area (15-1). When using an outside bell shape, the top end of the bellows (4) is fixed to an inside support ring by means of the neck end of the support bell. The air spring lid (16-1) is hinged to the vehicle structure (10) by a joint (22). The bell is out of rotation-symmetry and is designed cylindrical to open it elliptical to its open outer end.
