Abstract

Transmission à trains épicycloïdaux. La transmission comprend quatre trains épicycloïdaux permettant d'obtenir 6 rapports de vistesse en marche avant et un rapport de vitesse en marche arrière. Cette transmission permet d'obtenir par suppression d'éléments tels que couronne, freins ou embrayages des combinaisons à 5, 4 et 3 rapports de vitesse en marche avant et un rapport de vitesse en marche arrière. Application pour les automobiles, les véhicules de transport en commun et les véhicules industriels.
