Beschreibung
Zusammenfassung:	An air spring for a heavy-duty vehicle axle/suspension system includes a bellows chamber operatively connected to a piston chamber. An opening is disposed between the bellows chamber and the piston chamber in order to allow fluid to communicate between the bellows chamber and the piston chamber. The cross-sectional area of the opening and the volumes of the bellows chamber and the piston chamber are tuned in order to optimize the damping characteristics of the air spring. L'invention concerne un ressort pneumatique pour un système d'essieux/de suspension de véhicule lourd comprenant une chambre de soufflets fonctionnellement connectée à une chambre de pistons. Une ouverture est disposée entre la chambre de soufflets et la chambre de pistons afin de permettre au fluide de communiquer entre la chambre de soufflets et la chambre de pistons. La section de l'ouverture et les volumes de la chambre de soufflets et de la chambre de pistons sont réglés afin d'optimaliser les caractéristiques de suspension du ressort pneumatique.
