Abstract
UNA TRANSMISION DE RODILLO DE TRACCION VARIABLE INFINITAMENTE MULTIMODO QUE INCLUYE UNA TRANSMISION DE RODILLO DE TRACCION TOROIDAL (7,8) POR VARIAR INFINITAMENTE LA PROPORCION DE TRANSMISION EN CADA UNO DE LOS MODOS. LA POTENCIA ES TRANSMITIDA DESDE UN EJE DE ENTRADA (1) AL PORTADOR PLANETRIO (54) DE UNA TRANSMISION PLANETARIA (50-54) CUYO ANILLO (51) ESTA ASOCIADO CON EL EJE DE SALIDA (2) DE LA TRANSMISION Y A TRAVES DE LA TRANSMISION (7,8) AL SATELITE (50) DE LA TRANSMISION PLANETARIA (50-54) POR MEDIO DE UNA TRANSMISION POR CADENAS O ENGRANAJE RECTO (32,36;33,41) PROVISTO CON EMBRAGUES (C2,C3) PARA ENGRANAJE SELECTIVO DE ELLO, QUE ES, PARA LA ROTACION DEL SATELITE (50) EN UNA DIRECCION O LA OPUESTA. UNA ESTRUCTURA DE FRENO (29) ESTA PROVISTA PARA FIJAR EL PORTADOR PLANETARIO (54) EN UNO DE LOS MODOS DE TRANSMISION. LA VELOCIDAD DEL EJE DE SALIDA (2) ES INCREMENTAR POR INCREMENTAR LA VELOCIDAD DE SALIDA DE LA TRANSMISION (7,8) EN EL PRIMER MODO (MODO DIRECTO), ES ADEMAS INCREMENTADO POR DISMINUIR SUBSECUENTEMENTE LA VELOCIDAD DE SALIDA DE LA TRANSMISION (7,8) EN EL SEGUNDO MODO (MODO INVERSO) Y ES ENTONCES ADEMAS INCREMENTADO POR INCREMENTAR DE NUEVO LA VELOCIDAD DE SALIDA DE LA TRANSMISION EN EL TERCER MODO (MODO PAR DIVIDIDO). EL CAMBIO ESTA SUAVIZADO, POR ELLO MANTIENE UNA TRANSMISION VARIABLE INFINITAMENTE DE RANGO DE PROPORCION ANCHO.
