Abstract

Transmission hydromécanique. Elle comprend un arbre d'entrée, une pompe hydraulique à pistons orientés axialement associée à l'arbre et entraînée par ce dernier, un plateau oscillant pivotant associé à la pompe et faisant varier sélectivement son débit, un moteur hydraulique à pistons orientés axialement disposé coaxialement à la pompe et un plateau de distribution flottant disposé entre la pompe et le moteur et portant contre ces derniers. Une roue planétaire est portée par le moteur et une couronne dentée, par la pompe. Un support de sortie rotatif est disposé coaxialement à l'arbre et porte au moins un pignon satellite en prise à la fois avec la roue planétaire et avec la couronne dentée. L'énergie de sortie de la transmission est prise sur le support. Application à une transmission montée sur un avion et destinée à convertir la vitesse variable de son moteur en une vitesse constante permettant d'entraîner une génératrice ou des accessoires de l'avion.
