Abstract

CON UNA VALVULA DE FRENO DEBE PODER GOBERNARSE LA PRESION DE UNA CONDUCCION DE FRENO EN UNA ZONA LO MAS GRANDE POSIBLE DE POR EJEMPLO 0 - 5 BAR LINEALMENTE Y SIN INTERRUPCION POR INCLINACION DE UNA PALANCA. LA UTILIZACION DE LOS TORNILLOS HASTA AHORA HABITUALES PARA VARIACION DE LA TENSION ELASTICA ES POSIBLE SOLAMENTE PARA PEQUEÑAS ZONAS DE PRESION. CON AYUDA DE UNA PALANCA (20) SE GOBIERNA LA RELACION ENTRE LA FUERZA (A) DEL RESORTE (16) Y LA FUERZA (B) ACTIVADA POR LA PRESION DE CONDUCCION DEL FRENO, CON LO QUE LAS LONGITUDES DE LOS BRAZOS DE PALANCA (11,12) ACTIVOS SE AJUSTAN POR UNA PALANCA DE FRENO. EL RESORTE (16) SE APOYA SOBRE UN RODILLO (18) EN UNA SUPERFICIE DE APOYO (22) EN FORMA DE ARCO CIRCULAR DE TAL MODO QUE AL INCLINAR LA PALANCA DE FRENO (10,46) PERMANECE CONSTANTE LA FUERZA ELASTICA.
