Abstract
The invention is directed to an air spring system wherein an adequate carrying off of heat is ensured for a shock absorber (18) which is completely within an air spring (16) which includes a flexible member (4) and a roll-off piston (6). The interior spaces (12, 14) of the flexible member (4) and the roll-off piston (6) communicate with each other. In lieu of a conventional clamping plate, a funnel-shaped insert (22) is disposed between the flexible member (4) and the roll-off piston (6). The insert (22) surrounds the shock absorber (18) in such a manner that an annular nozzle-shaped narrow (23) results between the walls of the shock absorber (18) and the inner surface of the funnel-shaped insert (22). Openings (26) are disposed on the outer region of the insert (22). These openings (26) as well as the nozzle-shaped narrow (23) define a connection between the volume (12) of the flexible member (4) and the volume (14) of the roll-off piston (6). An air circulation (30) with an air flow along the wall of the shock absorber (18) results during spring compression and spring expansion.
