Abstract
L’invention concerne une suspension pneumatique (1) comprenant un vérin pneumatique destiné à être interposé entre une portion d’un véhicule (7) roulant et un appui au sol (6) dudit véhicule, le vérin pneumatique présentant un volume interne (Vp) de réserve d’air. Le volume (Vp) est connecté pneumatiquement à au moins deux cellules (3a, 3b) comportant un volume d’air additionnel (V1, V2) respectif avec une restriction (R1, R2) disposée à l’entrée de chacun des volumes additionnels (V1, V2) piqués en parallèle sur une conduite (5) débouchant dans le volume (Vp), une électrovanne (4), positionnée entre le volume (Vp) et les volumes additionnels (V1, V2) des cellules (3a, 3b), fermant une circulation d’air dans la conduite (5) dans une première position correspondant à un mode à raideur augmentée de la suspension, et l’ouvrant dans au moins une deuxième position correspondant à un mode d’amortissement doux de la suspension.
