Abstract

ESTA INVENCION SE RELACIONA CON UN DISPOSITIVO ACCIONADOR PARA VARIAR LA RELACION DE UNA TRANSMISION VARIABLE CONTINUA EN UN VEHICULO EQUIPADO CON UN MOTOR DE COMBUSTION INTERNO. EL DISPOSITIVO CONSTA DE DOS MANGUITOS (11, 12) DOTADOS RESPECTIVAMENTE DE UN TORNILLO PRINCIPAL (16) Y UNO INTERNO (15) ENCAJADOS UNO EN OTRO DE MANERA QUE EL GIRO RELATIVO SE TRANSFORME EN TRASLACION RELATIVA. LOS MANGUITOS CONSTAN DE ACANALADURAS ANULARES (17A, 17B) QUE LES PERMITEN GIRAR LIBREMENTE EN RELACION UNO CON OTRO SIN NINGUNA TRASLACION MIENTRAS QUE LOS MANGUITOS SE HALLEN EN EL ESTADO DE MAXIMA PENETRACION RECIPROCA. LA FUNCION DEL DISPOSITIVO ACCIONADOR SE EFECTUA PREFERENTEMENTE MEDIANTE EL MISMO MOTOR ELECTRICO QUE SE UTILIZA PARA ARRANCAR EL MOTOR DE COMBUSTION INTERNA.
