Abstract

Una transmisión variable comprende un eje de entrada (18) un disco de entrada (10) montado en el eje de entrada para giro en el mismo y un disco de salida (12) orientado hacía el disco de entrada y arreglado para girar de manera coaxial en el mismo, los discos de entrada y salida definiendo entre los mismos una cavidad toroidal. Dos rodillos (14,16) son ubicados en la cavidad toroidal y el primero y segundo medio de operación del primer y segundo rodillo son proporcionados cuyo primer y segundo rodillo respectivamente son montados de manera giratoria y los medios de carga extremos (34, 36) llevan a los rodillos en contacto con los discos de entrada y salida para transmitir la operación. El medio de operación de dos rodillos es montado en las partes opuestas del eje del pivote de una palanca (50) y el eje del pivote de la palanca (50) es movible en direcciones radiales y no radiales con relación al eje rotacional de la entrada y los discos de salida.
