Abstract

UN FRENO DE EMERGENCIA PARA UN COCHE ELEVADOR. EL PROBLEMA CON LOS FRENOS DE COCHE ES LA FUERZA DE FRENADO DESIGUAL APLICADA Y EL DESGASTE DESIGUAL DE LAS GUARNICIONES. EL ELEVADOR EMPLEA RESORTES QUE MANTIENEN UNA FUERZA DE FRENADO CONSTANTE SOBRE LAS ZAPATAS. LOS RESORTES (15, 16) ESTAN COMPRIMIDOS A TRAVES DE UN PISTON ACCIONADO POR LIQUIDO Y UN MONTAJE (35) CILINDRICO. LOS RESORTES (15, 16) MUEVEN UN RODILLO DE LEVA (17) A LO LARGO DE LAS SUPERFICIES DE LEVA (20, 21) CONFIGURADAS PARA ORIGINAR QUE EL RODILLO DE LEVA (17) MUEVA UNA ZAPATA (22) DEL FRENO HACIA LA OTRA ZAPATA (24). INTERRUPTORES (63, 57) QUE FUNCIONAN A TRAVES DEL RODILLO DE LEVA (17) CONTROLAN EL COCHE (4) DE MODO QUE SE PREVIENE EL MOVIMIENTO DEL COCHE (4) CUANDO LOS RESORTES (15, 16) NO ESTAN COMPRIMIDOS Y CUANDO HAY UN USO EXCESIVO DE LA ZAPATA.
