Abstract

MECANISMO DE ACCIONAMIENTO DE LA CATALINA DE BICICLETAS. EL MECANISMO ESTA PREVISTO PARA CONSEGUIR QUE LAS BIELAS DEL CONJUNTO PEDALIER DE UNA BICICLETA PUEDAN ALARGARSE Y/O ACORTARSE DURANTE LOS RECORRIDOS DE GIRO DESCENDENTE Y/O ASCENDENTE, RESPECTIVAMENTE DE LOS PROPIOS PEDALES DE ACCIONAMIENTO, DANDO LUGAR A QUE DURANTE EL RECORRIDO DE MAYOR ESFUERZO QUE ES EL DESCENDENTE LA BIELA SE ALARGUE Y ADQUIERA UN MAYOR BRAZO DE PALANCA, MIENTRAS QUE EN EL RECORRIDO ASCENDENTE EN DONDE EL ESFUERZO ES PRACTICAMENTE NULO LA BIELA SE ACORTA REDUCIENDOSE CON ELLO EL RECORRIDO CIRCUNFERENCIAL DEL PROPIO PEDAL. EL MECANISMO ESTA BASADO EN QUE EL EJE (3) EN EL QUE VAN MONTADAS LAS BIELAS ES FIJO Y ESTA SOLIDARIZADO EXCENTRICAMENTE EN EL INTERIOR DE UN CILINDRO HUECO (2) QUE EN SU PERIFERIA CUENTA CON SENDOS RODAMIENTOS (5) A LOS QUE SE SOLIDARIZAN LOS CASQUILLO (13) EN LOS QUE JUEGAN RODILLOS DE GIRO LIBRE (12) EMERGENTES DE LA CARA INTERNA DE LOS BRAZOS (7) QUE CONSTITUYEN LAS BIELAS JUNTO CON PIEZAS(6) MONTADAS PRECISAMENTE EN LOS EXTREMOS DEL EJE (3), ESTANDO EL BRAZO (7) VINCULADO A LA PIEZA (6) CON FACULTAD DE DESPLAZAMIENTO AXIAL RESPECTO DE ESTA.
