Abstract

L'invention concerne une transmission de puissance à variation continue hydromécanique destinée qui transforme une puissance mécanique de rotation selon une combinaison de vitesse et un couple de rotation en une autre combinaison de vitesse et de couple de rotation sur une plage continue, qui comporte une pompe hydraulique, fonctionnellement entraînée par un arbre d'entrée, et un moteur hydraulique entraînant fonctionnellement un arbre de sortie. La pompe et le moteur hydrauliques sont couplés mécaniquement par le biais d'une paire de trains planétaires; ils sont également couplés hydrauliquement par le biais d'une rampe, ainsi, le fluide hydraulique sous pression par ladite pompe entraîne le moteur, et le fluide utilisé par le moteur est recyclé vers la pompe où il est mis une nouvelle fois sous pression. Les deux trains planétaires sont disposés coaxialement avec l'arbre d'entrée et l'arbre de sortie, la pompe et le moteur hydrauliques étant disposés en série, chacun de part et d'autre de la rampe, et parallèles aux arbres d'entrée et de sortie, ce qui permet d'optimiser l'utilisation de l'espace et de maintenir au minimum la longueur globale de la transmission, et de réduire les longueurs requises desdits arbres d'entrée et de sortie.
