Abstract

Système d'accumulation de pression prévu pour un circuit hydraulique d'un véhicule hybride disposant de machines hydrauliques (20, 22) liées à une transmission (4) entraînant les roues du véhicule, qui délivrent une haute pression à un accumulateur de pression à gaz (46) de ce système, caractérisé en ce qu'il comporte une enceinte fermée de protection aux chocs (56) comprenant à l'intérieur l'accumulateur de pression (46), une commande d'entrée du fluide (48) dans cet accumulateur qui est sécurisée en cas d'absence de signal, et un moyen d'échappement contrôlé des gaz (52) en dehors de l'enceinte (56) en cas de surpression.
