Abstract

Il comprend un pignon métallique d'entrée du mouvement. solidaire de l'arbre d'entraînement qui engrène simultanément avec des roues d'engrenage avec couronnes à denture hélicoïdale en matière plastique renforcée; lesdites roues étant destinées à la commande des plateaux intermédiaires, en vue de leur entraînement souple. L'invention peut être utilisée pour tout type de variateur de vitesse à friction et à plateaux intermédiaires.
