Abstract

UN COMPONENTE VARIADOR DE LA RELACION PARA UNA TRANSMISION DEL TIPO RODANTE DE CARRERA TOROIDAL, EN QUE CADA UNO DE LOS RODILLOS (1) QUE TRANSMITEN EL PAR ENTRE UN DISCO DE ENTRADA (51, FIG. 3) Y UN DISCO DE SALIDA CORRESPONDIENTE (40) SE ENCUENTRA COLOCADO HIDRAULICAMENTE MEDIANTE UN PISTON HIDRAULICO ACOPLADO (5) Y UNA COMBINACION DE CILINDROS (6), EN QUE TODOS LOS CILINDROS SE ENCUENTRAN COLOCADOS EN EL MISMO LADO DE UN PLANO COMUN (43A) QUE INCLUYE EL EJE (43) DE LOS DISCOS. LOS CILINDROS PUEDEN ESTAR SOPORTADOS EN UNA ESTRUCTURA TIPO BLOQUE COMUN (419, DENTRO DE LA CUAL PUEDE HABER UNOS CONDUCTOS HIDRAULICOS (31A, 32A, 37A, 44).
