Abstract

UN PAR DE ZAPATAS DE FRENO (36), DISPUESTAS MUTUAMENTE ENFRENTADAS, ESTAN PREVISTAS PARA COOPERAR CON LAS SUPERFICIES LATERALES DE UNA LLANTA (F), ESTANDO FIJADA CADA UNA DE ELLAS EN EL EXTREMO DE UN BRAZO (30, 31) DE UNA PINZA DE FRENO (29). ESTOS BRAZOS (30, 31) PUEDEN GIRAR CONJUNTAMENTE, CONTRA LA ACCION DE UN RESORTE DE REPOSICION (47), EN UN PLANO PERPENDICULAR A LA DIRECCION DE LA FUERZA DE FRICCION, AL MISMO TIEMPO, QUE LAS ZAPATAS DE FRENO SE PUEDEN DESPLAZAR DE FORMA LIMITADA EN UNA DIRECCION PERPENDICULAR AL EJE DE GIRO. LOS BRAZOS (30, 31) COOPERAN CON UNA SUPERFICIE INCLINADA (23, 24) PARA SER PRESIONADOS CON MAYOR FUERZA CONTRA LA SUPERFICIE LATERAL (F) CORRESPONDIENTE DE LA LLANTA DURANTE EL MOVIMIENTO DE DESPLAZAMIENTO DE LAS ZAPATAS DE FRENO (36). PARA REDUCIR EL PELIGRO DEL AGARROTAMIENTO DE LOS BRAZOS (30, 31) AL TENSAR EL FRENO Y, CON ELLO, EL BLOQUEO DE LA RUEDA (11) FRENADA, SE APOYA CADA UNO DE LOS EXTREMOS DE LOS DOS BRAZOS (30, 31) A TRAVES DE UNA RUEDA (51) LIBREMENTE GIRATORIA EN SUPERFICIES INCLINADAS (23, 24), QUE CONVERGEN EN LA DIRECCION DE LA FUERZA DE FRICCION Y QUE ESTAN FIJADAS AL CUADRO (12, 13) DE LA BICICLETA. CADA UNO DE LOS BRAZOS (30, 31) PUEDE GIRAR ALREDEDOR DE UNA ESPIGA DE GIRO (33, 34'') PROPIA Y LAS SUPERFICIES INCLINADAS (23, 24) ASI COMO LAS RUEDAS (51) SE DISPONEN ENTRE LA ZAPATA DE FRENO (36) CORRESPONDIENTE Y LA ESPIGA DE GIRO (33, 34'').
