Abstract

SE PRESENTA UNA TRANSMISION DE RELACION CONTINUAMENTE VARIABLE QUE COMPRENDE UNA UNIDAD DE VARIACION DE LA RELACION ("VARIADOR"), Y UNA UNIDAD EPICICLICA QUE TIENE TRES SALIDAS CONCENTRICAMENTE DISPUESTAS. DOS DE ESTAS SALIDAS ESTAN RESPECTIVAMENTE CONECTADAS EN UNA RELACION FIJA A LOS EXTREMOS OPUESTOS DEL VARIADOR, DE MANERA QUE LA RELACION DEL VARIADOR CAMBIE, LA VELOCIDAD DE UNA DE ESTAS SALIDAS SIEMPRE AUMENTA Y LA DE LA OTRA DISMINUYE. ESTAS DOS SALIDAS ESTAN TAMBIEN CONECTADAS MEDIANTE UN ENGRANAJE APROPIADO Y EMBRAGUES APROPIADOS AL EJE DE SALIDA CVT. SE OBTIENEN REGIMENES SUCESIVOS DE FUNCIONAMIENTO, DE MANERA QUE SE EXTIENDA LA GAMA TOTAL DE RELACION DEL CVT, CONECTANDO ALTERNATIVAMENTE CADA UNA DE LAS DOS SALIDAS EPICICLICAS A LA SALIDA DEL CVT. LAS RELACIONES Y OTROS PARAMETROS SE ESCOGEN DE MANERA QUE LOS CAMBIOS DE REGIMEN SEAN SINCRONICOS.
