Abstract

Transmission infiniment variable à cales pour transmettre le couple d'un élément d'entraînement à un élément entraîné. En faisant varier la valeur de l'excentricité entre les deux éléments, les cales ajoutent du mouvement, par action de basculement ce qui procure différents rapports d'entraînement. Application à une transmission pour bicyclettes dans laquelle un tambour d'entrée à entraînement par chaîne est monté à excentrement sélectif par rapport à un tambour situé sur l'arbre d'une roue
