Abstract

Dispositif de transmission à rapport variable automatique, à courroie trapézoïdale, comprenant des poulies réglables dont chacune au moins comporte une moitié de poulie pouvant être déplacée axialement. Le rapport de transmission entre les poulies est pratiquement constant dans une portion déterminée de la zone de vitesse de rotation du moteur; ce rapport constant peut être obtenu notamment par la forme 14 d'une surface de came de masses centrifuges 8. Application à l'entraînement d'un véhicule.
