Abstract

EN UNA TRANSMISION VARIABLE INFINITAMENTE EN DONDE DOS DISCOS (20,22) DE TRACCION TORICOS SON GIRATORIAMENTE SOPORTADOS EN UN ALOJAMIENTO (10) OPUESTO UNO A OTRO PARA DEFINIR ENTRE ELLOS UNA CVIDAD TORICA (24) EN LA QUE AL MENOS DOS RODILLOS (26,28) DE TRACCION QUE TRANSMITEN EL MOVIMIENTO SON DISPUESTOS EN COMPROMISO CON LOS DISCOS TORICOS (20,22) Y SOPORTADOS POR MUÑONES PIVOTES (30,32), CADA MUÑON (30,32) ES PROVISTO CON UN RODILLO (34,36) SOPORTE SIMPLE DISPUESTO EN UNA SECCION (54) Y TIENE UN EXTREMO (56) DE CONTROL AXIAL QUE ES SOPORTADO PARA SER LIGERAMENTE MOVIL EN UN PLANO NORMAL AL EJE DE LOS DISCOS (20,22) TORICOS Y MEDIOS (62-70) SON PROVISTOS PARA MOVER CONTROLABLEMENTE LOS EXTREMOS DE CONTROL DE MUÑON (56) EN ARMONIA PARA LA INICIACION DE UN CAMBIO DE RELACION DE TRANSMISION. EN ESTA MANERA LOS CAMBIOS DE RELACION SON INICIADOS MECANICAMENTE EN UNA MANERA SIMPLE.
