Abstract

Système hydraulique pour une boîte de vitesse à double embrayage Système hydraulique (HY) pour une boîte de vitesse à double embrayage (G) d’un groupe motopropulseur de véhicule automobile, dans lequel le système hydraulique (HY) comporte une première pompe (EP) destinée à l’alimentation en pression d’un premier circuit de pression (H1) et une deuxième pompe (MP) destinée à l’alimentation en pression d’un deuxième circuit de pression (H2), dans lequel le premier circuit de pression (H1) est prévu au moins pour l’actionnement hydraulique d’un double embrayage (K1, K2) de la boîte de vitesse à double embrayage (G), et le deuxième circuit de pression (H2) est prévu au moins pour la lubrification d’autres composants de la boîte de vitesse à double embrayage (G), dans lequel la première pompe (EP) peut être entraînée par un moteur électrique (EM1) affecté exclusivement à la première pompe (EP) qui n’est pas agencé pour l’entraînement du véhicule automobile, dans lequel la deuxième pompe (MP) peut être entraînée par une unité d’entraînement (VM, EM2) du groupe motopropulseur de véhicule automobile. L’invention concerne en outre un procédé de fonctionnement du système hydraulique (HY) et une boîte de vitesse à double embrayage (G) dotée du système hydraulique (HY).
