Abstract

Transmission pour commande de traction, notamment véhiculaire. Une seule commande forme une gamme de rapports de vitesse entre les arbres d'entrée et de sortie sans raccordement de l'embrayage au moteur. Une combinaison de galets de friction complètement mécaniques et de systèmes planétaires d'engrenage sont raccordés en permanence, pour marche avant, arrêt ou marche arrière de l'arbre de sortie. Une réaction automatique de changement vers le bas à une charge croissante, et des forces de réaction axiale majeures rendues indépendantes par le mécanisme de rotation, évitent les composantes de force axiale sur les roulements principaux du mecanisme. Applicable notamment aux véhicules pour menus travaux, jardinage, etc.
