Abstract
A spring arrangement includes two coaxial spring components (4a, 4b) which are mounted so as to oppose each other. Each of the spring components includes a rolling-lobe flexible member (6a, 6b) and a roll-off piston (8a, 8b) corresponding thereto. The two rolling-lobe flexible members (6a, 6b) define a common double rolling-lobe flexible member (6) and the two spring components (4a, 4b) have a common outer jacket (10). A simple assembly and a reliable fixation of the double rolling-lobe flexible member (6) on the outer jacket (10) is provided. For this purpose, the double rolling-lobe flexible member (6) has a clamp ring (18 or 26) mounted internally. The outer jacket (10) includes two parts (10a and 10b) having respective ends. The double rolling-lobe flexible member (6) is clamped between these ends with the aid of the clamp ring (18 and 26). The air spring arrangement is especially applicable in the forward wheel fork (16) of a two-wheel vehicle.
