Abstract

SISTEMA DE CONTROL DEL RODILLO PARA UNA TRANSMISION DE RELACION CONTINUA-VARIABLE DEL TIPO DE PISTA TOROIDAL Y TRACCION DE RODAMIENTO, EN EL QUE RODILLOS (60) DE ORIENTACION VARIABLE TRANSMITEN LA TRACCION ENTRE UNA PISTA EN PARTE TOROIDAL (85) FORMADO SOBRE UN DISCO DE ENTRADA (61) Y UNA PISTA SIMILAR (87) FORMADA SOBRE UN DISCO DE SALIDA COAXIAL (62). CADA UNO DE LOS RODILLOS ESTA MONTADO DE FORMA QUE GIRE A LO LARGO DE UN CENTRO FIJO (66) Y UN EJE FIJO (58) DENTRO DE UN CARRO RIGIDO (67), UNO DE CUYOS EXTREMOS CONTACTA DE FORMA RECIPROCA CON UN MECANISMO OPERATIVO SOBRE UN RECORRIDO PREDETERMINADO DE MOVIMIENTO OPERATIVO Y ACCIONABLE DE MODO QUE APLIQUE UNA FUERZA DE CONTROL AL CARRO. EL ENSAMBLAJE DE RODILLO Y CARRO SE COLOCA MEDIANTE SOLO TRES CONTACTOS CON ESTRUCTURA CONTIGUA, ES DECIR, LOS DOS CONTACTOS DE DISCO/RODILLO (86, 88) Y EL CONTACTO (82) CON EL MECANISMO OPERATIVO. ESTOS TRES CONTACTOS BASTAN PARA HACER QUE EL RODILLO BUSQUE CONTINUAMENTE UN ANGULO DE RELACION EN EL QUE ELVALOR INSTANTANEO DE LA FUERZA DE CONTROL QUEDA COMPENSADO POR EL VALOR INSTANTANEO DE LAS FUERZAS DE TRACCION A LAS QUE ESTA SUJETO EL ENSAMBLAJE DEL RODILLO DEBIDO AL CONTACTO ENTRE EL RODILLO Y LOS DOS DISCOS, Y EN EL QUE LA TRANSMISION ESTE, POR CONSIGUIENTE, EN EQUILIBRIO.
