Abstract
TITRE : Système hydraulique de compensation de pression de frein Système hydraulique de frein comprenant deux circuits de freinage (CF1,2) identiques, fonctionnant en parallèle et actionnant des freins indépendants (FR1,2), chaque circuit de freinage se composant d’un réservoir de liquide de frein (RES1,2) alimentant de façon commandée son frein hydraulique à la pression demandée (P1, P2) par un tiroir de commande (TC1,2) associé au frein et à l’extrémité de commande du tiroir est actionné par un dispositif de commande (120), les deux tiroirs commandant l’alimentation et le réglage de la pression de freinage (P1, P2) dans leur circuit (CF1,2), système caractérisé en ce qu’il comprend un dispositif de compensation de pression (130) recevant les deux pressions de freinage (P1, P2) et appliquant à l’extrémité de commande du tiroir (TC) fournissant la pression la plus faible, la pression de l’autre tiroir de commande (TC) fournissant la pression la plus forte des deux pressions (P1, P2).
