Abstract
Mécanisme pour faire varier la vitesse angulaire relative de deux arbres d'une manière proportionnellement continue. Le mécanisme comprend, entre les deux arbres, une unité de transmission comportant une pluralité d'éléments tournant autour d'un axe, chaque élément pouvant établir une liaison d'accouplement entre un des arbres et un organe tournant pour un angle limité de rotation dudit arbre, la distance entre les éléments et l'axe de l'arbre ou de l'organe tournant, lorsqu'il se trouve dans la position d'accouplement, pouvant être modifiée par des moyens de réglage en vue de faire varier la vitesse angulaire re ative des deux arbres d'une manière proportionnellement continue. Application aux boîtes de vitesses pour véhicules automobiles.
