Abstract

L'invention concerne une transmission (100) pour un ensemble d'entraînement hybride, laquelle peut être couplée à deux groupes d'entraînement (8, 9), comprenant un arbre d'entrée (10) et un arbre de sortie (11), au moins un premier élément de changement de vitesse et un deuxième élément de changement de vitesse (SE1, SE2), et une première, une deuxième et une troisième boîte à engrenages planétaires (5, 6, 7). La cage de transmission planétaire (P1) de la première boîte à engrenages planétaires (5) est couplée à la couronne (H3) de la troisième boîte à engrenages planétaires (7), et la couronne (H1) de la première boîte à engrenages planétaires (5) est couplée à la cage de transmission planétaire (P2) de la deuxième boîte à engrenages planétaires (6), et la couronne (H2) de la deuxième boîte à engrenages planétaires (6) est couplée à la cage de transmission planétaire (P3) de la troisième boîte à engrenages planétaires (7). Le premier élément de changement de vitesse est mis au point pour ralentir ou débloquer la roue solaire (S3) de la troisième boîte à engrenages planétaires (7). Le deuxième élément de changement de vitesse est mis au point pour ralentir ou débloquer la roue solaire (S1) de la première boîte à engrenages planétaires (5). L'arbre d'entrée (10) est couplé à la roue solaire (S2) de la deuxième boîte à engrenages planétaires (6). L'arbre de sortie (11) est couplé à la couronne (H2) de la deuxième boîte à engrenages planétaires (6) et à la cage de transmission planétaire (P3) de la troisième boîte à engrenages planétaires (7).
