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