Abstract

A.ENSEMBLE DE TRANSMISSION A RAPPORT DE VITESSES VARIABLE. B.ENSEMBLE DE TRANSMISSION CARACTERISE EN CE QUE L'ORGANE DE TRANSMISSION SANS FIN EST CONSTITUE D'UN MATERIAU METALLIQUE ESSENTIELLEMENT RIGIDE ET REVET LA FORME D'UNE CHAINE OU D'UN ORGANE ANNULAIRE, LES DEUX POULIES A GORGES EN FORME DE V ETANT MONTEES DANS UN CARTER ETANCHE CONTENANT UN FLUIDE DE TRACTION, ET L'ORGANE DE TRANSMISSION SANS FIN ETANT EN LIAISON D'ENTRAINEMENT PAR TRACTION AVEC LES DEUX POULIES PAR L'INTERMEDIAIRE D'UN FILM DE CE FLUIDE. C.L'INVENTION S'APPLIQUE NOTAMMENT A LA COMMANDE D'APPAREILS AUXILIAIRES SUR DES VEHICULES AUTOMOBILES.A. VARIABLE GEAR RATIO TRANSMISSION ASSEMBLY. B. TRANSMISSION ASSEMBLY CHARACTERIZED IN THAT THE ENDLESS TRANSMISSION UNIT CONSISTS OF AN ESSENTIALLY RIGID METAL MATERIAL AND SHALL BE SHAPED AS A CHAIN OR AN ANNULAR BODY, THE TWO V-SHAPED PULLEYS BEING MOUNTED IN A SEALED CASING CONTAINING A TRACTION FLUID, AND THE ENDLESS TRANSMISSION UNIT BEING LINKED TO THE DRIVE BY TRACTION WITH THE TWO PULLEYS THROUGH A FILM OF THIS FLUID. C. THE INVENTION APPLIES IN PARTICULAR TO THE CONTROL OF AUXILIARY EQUIPMENT ON MOTOR VEHICLES.
