Abstract:
A seal arrangement for an air spring system for sealing off a shock-absorbing damper is disclosed. The shock-absorbing damper is situated in a rolling tube and in another tube, where the air spring system has at least one integrated control valve for the admission of compressed air into a pressure chamber formed between the outer tube, the rolling tube, and an air spring bellows that connects the outer tube and rolling tube. The seal arrangement is arranged between an inner circumferential surface of the rolling tube and an outer circumferential surface of the shock-absorbing damper and/or between an inner circumferential surface of the outer tube and the outer circumferential surface of the shock-absorbing damper. A support ring which is of step-shaped form on an outer circumferential surface is arranged on a distal end of the rolling tube and/or on a distal end of the outer tube.
