Abstract

L'invention porte sur une transmission à variation continue (64, 46, 48) comportant plusieurs couplages visqueux (64, 46, 48) et un ensemble de trains planétaires (20, 62, 92) à transmission de puissance par la roue solaire (30). Le couplage visqueux de départ (46) assure le démarrage à faible vitesse (46) et le couplage visqueux à rapport variable (48) commande le rapport des vitesses de sortie. Le couplage visqueux réversible (64) est doté d'une commande d'inversion. La vitesse maximale de sortie est atteinte lorsque le couplage visqueux à rapport variable (48) fonctionne à plein.
