PROBLEM TO BE SOLVED: To eliminate a crimp process of a guide tube and eliminate a support ring, by directly connecting a rolling bellow to the guide tube during molding of a bellow.SOLUTION: A pneumatic spring 10' contains a bellow 14 defining at least partially at least one work chamber 12 that is arranged and constituted so as to be filled with compressed air. A guide tube 18' encloses at least a part of the bellow 14. A part of the bellow 14 is fixed to the guide tube 18' only with bonding agent 36. A piston 16 cooperates with the bellow 14. The bellow 14 is arranged and constituted so as to roll on the outer surface of the piston 16 and the inner surface of the guide tube 18'.SELECTED DRAWING: Figure 2 |
