Abstract

L'invention concerne un composant de transmission variable à l'infini qui comprend un disque d'entrée et un disque de sortie. Chaque disque est pourvu d'un chemin de roulement, les chemins de roulement du disque d'entrée et ceux du disque de sortie se faisant face. Des galets sont placés entre ces disques, qui possèdent une surface entrant en prise avec les chemins de roulement, et l'on peut changer la position des galets d'entraînement par rapport aux disques afin de modifier le rapport de transmission entre les disques. Au moins un des disques et de galets d'entraînement est fait à partir de l'acier de type PM M62.
