Abstract

GRUPO DE TRANSMISION DE RELACION VARIABLE ENTRE ARBOLES DE ENTRADA Y SALIDA. INCLUYE UN VARIADOR DE VELOCIDAD QUE INTRODUCE UNA VARIACION CONTINUA DE RELACION ENTRE UN PRIMER ARBOL (9, 10) Y UN SEGUNDO ARBOL(6). LOS ENLACES ENTRE EL ARBOL DE ENTRADA (1) Y EL PRIMER ARBOL DEL VARIADOR, ASI COMO ENTRE EL SEGUNDO ARBOL DEL MISMO Y EL ARBOL DE SALIDA (14), SON REALIZADOS POR DOS DISPOSITIVOS DE ACOPLAMIENTO DESACOPLABLES. EXISTEN DOS REDUCTORES ADICIONALES DESACOPLABLES, ENTRE EL ARBOL DE ENTRADA Y EL SEGUNDO ARBOL DEL VARIADOR, ASI COMO ENTRE EL PRIMER ARBOL Y EL ARBOL DE SALIDA. LAS DOS RELACIONES DE REDUCCION DE DICHOS REDUCTORES DESACOPLABLES SON ELEGIDAS DE MODO QUE, CUANDO EL VARIADOR ASEGURA LA DESMULTIPLICACION MAXIMA ENTRE EL PRIMERO Y EL SEGUNDO ARBOLES, EL DESACOPLAMIENTO DE LOS DOS ACOPLAMIENTOS, Y EL DESACOPLAMIENTO DE LOS DOS REDUCTORES, NO PRODUZCA NINGUNA VARIACION DE VELOCIDAD NI DE SENTIDO DE ROTACION DE LOS ARBOLES. DE APLICACION EN VEHICULOS A MOTOR.
