Abstract

La présente invention concerne une transmission variable (1) comprenant un train épicycloïdal qui comporte des satellites (10) sous la forme de galets coniques ou tronconiques, ainsi que deux planétaires intérieurs (3, 5), et un porte-satellite (9). Le porte-satellite (9) est prévu pour qu’une génératrice (GG) des galets coniques ou tronconiques soit parallèle à l’axe (AA) des planétaires intérieurs. Figure 1 à publier
