Abstract

L'invention concerne une transmission automatique pour véhicule automobile, comprenant une dérivation sélective autour d'une unité hydrocinétique pour la transmission d'une partie du couple moteur. La transmission comprend un arbre d'entrée 1, une pompe 3a et une turbine 3b, un arbre de sortie 2, des embrayages C1 et C2 , un diviseur formé par un groupe X de pignons planétaires, et un train de pignons comprenant deux groupes Y et Z de pignons planétaires. L'invention permet une économie de carburant pour les véhicules équipés de transmission automatique de changement de vitesse.
