Abstract

The invention relates to a system having an air spring flexible member (6) which is clamped between a cover plate (4) and a rolloff piston (10). The movement of the rolloff piston (10) is pregiven by a curved path (16). The rolloff piston (10) is curved with the curvature being at least segmentwise of the same orientation as the curvature of the curved path (16). Because of the curvature of the rolloff piston (10), a lateral offset of the flexible member (6) to the cover plate (4) can be substantially avoided when the rolloff piston (10) plunges into the flexible member (6). The formation of a rolling lobe (20) having a different width over its periphery is also avoided.
