Abstract

EN UNA TRANSMISION VARIABLE INFINITAMENTE, DONDE DOS DISCOS (20, 22) DE TRACCION TOROIDAL SE SOSTIENEN, DE FORMA QUE PUEDEN GIRAR, UNO FRENTE A OTRO PARA DEFINIR ENTRE ELLOS UNA CAVIDAD TOROIDAL EN LA QUE SE COLOCAN POR LO MENOS DOS RODILLOS (26, 28) DE TRACCION PARA TRANSMISION DE MOVIMIENTO ACOPLADOS CON LOS DISCOS TOROIDALES (20, 22) Y SOSTENIDOS POR SOPORTES GIRATORIOS (30, 32), Y SE FACILITAN ELEMENTOS (66, 68, 70) PARA HACER GIRAR , DE FORMA QUE PUEDAN CONTROLARSE, LOS SOPORTES GIRATORIOS (30, 32) PARA CAMBIAR EL INDICE DE TRANSMISION, SE COLOCAN ENLACES TRANSVERSALES (86, 88) EN LAS CARAS EXTREMAS DE LOS SOPORTES GIRATORIOS (30, 32) PARA PERMITIR EL MOVIMIENTO PIVOTANTE DE LOS SOPORTES GIRATORIOS (30, 32) SOLO AL UNISONO Y EN SENTIDO OPUESTO, Y LOS ENLACES TRANSVERSALES (86, 88) TIENEN SECCIONES CENTRALES SUPERPUESTAS CON SUPERFICIES DE PARADA COLOCADAS PARA ACOPLARSE UNAS A OTRAS EN LAS POSICIONES EXTREMAS PIVOTANTES DE LOS SOPORTES GIRATORIOS (30, 32) PARA LIMITAR SU MOVIMIENTO PIVOTANTE.
