Abstract

Un train d'engrenages (1) est disposé dans le carter général d'une boîte à plusieurs vitesses. Le train planétaire (11) est placé dans le carter principal (2, 20) et l'embrayage (15) du train d'engrenages (1) dans un deuxième carter (3, 30). Un élément de transmission (16) de l'embrayage (15) est supporté sur le carter au moyen d'une plaque intermédiaire (4, 40, 400). Cette plaque intermédiaire est en mesure de transmettre des couples élevés de l'organe d'embrayage au carter de la boîte de vitesses.
