An improved airspring assembly includes a collapsible support member (44) disposed within the pressurizable chamber (16) of an airspring (10) having a flexible sidewall (14). The support member (44) is configured such that it extends and collapses along a longitudinal axis of the chamber (16) responsive to pressurization and depressurization of the chamber (16), respectively. The support member (44) also is configured such that it retains a substantially rigid outer perimeter, thereby restricting movement of the chamber's flexible sidewall (14) toward the longitudinal axis when the chamber (16) is depressurized. The support member (44) also is configured such that it does not interfere with the full stroke of the airspring (10).The support member (44)is configured as a helical spring (44).
L'invention concerne un ressort pneumatique amélioré comprenant un élément de support pliable (44) disposé dans la chambre sous pression (16) d'un ressort pneumatique (10) pourvu d'une paroi flexible (14). Cet élément de support (44) est configuré de manière à s'étendre et à se plier le long d'un axe longitudinal de la chambre (16) en réponse à une pressurisation et dépressurisation de la chambre (16). L'élément de support (44) est également configuré de manière à retenir un périmètre externe sensiblement rigide, ce qui permet de restreindre le mouvement de la paroi flexible (14) de la chambre vers l'axe longitudinal lorsque la chambre (16) est dépressurisée. L'élément de support (44) est également configuré de manière à ne pas être en interface avec l'impulsion du ressort pneumatique (10). L'élément de support (44) est configuré en ressort hélicoïdal.
