ABSTRACT:
A double rolling-lobe flexible member spring arrangement (2) includes two coaxial spring components (4aand4b) which are arranged opposed to each other. The spring components essentially each include a rolling-lobe flexible member (6aand6b) and respective roll-off pistons (8aand8b). The two rolling-lobe flexible members (6and6b) define a common double rolling-lobe flexible member (6) and the two spring components (4aand4b) have a common outer jacket (10). A reliable effective fixing of the flexible member (6) to the inner side of the outer jacket (10) is ensured. To provide this fixation, the double rolling-lobe flexible member (6) has a support ring (14) lying centrally on the inner side thereof and this support ring has a radial recess (16) on its periphery. The outer jacket (10) has a peripherally-extending raised portion at its inner periphery which engages into the recess (16) of the support ring (14) and defines a clamp contour.
