Abstract

UN DETECTOR DE DESGASTE DE REVESTIMIENTO INTERIOR COMPRENDE UNA TIRA (9) DISCRETA DE CAPAS MULTIPLES, DE MATERIAL ELECTRICAMENTE CONDUCTIVO, QUE SE ADHIERE AL BORDE (6) DE UN AMORTIGUADOR (2) DE FRICCION, DE MODO QUE SE DESGASTE CON EL AMORTIGUADOR, CON UN CAMBIO POSTERIOR EN LA RESISTENCIA ELECTRICA DE SU CAPA (11) DE MATERIAL RESISTIVO. ESTO PUEDE MEDIRSE MEDIANTE CONTACTOS ADECUADOS PARA INDICAR EL ESTADO DE DESGASTE DEL AMORTIGUADOR. CUANDO EL MATERIAL RESISTIVO TIENE UN COEFICIENTE DE RESISTENCIA ELEVADO DE TEMPERATURA, SE PUEDEN MONITORIZAR LOS CAMBIOS DE TEMPERATURA EN LA TIRA (9) Y EN EL PROPIO MATERIAL DE FRICCION, PARA PROPORCIONAR UNA INDICACION DE LAS CARACTERISTICAS DEL FRENO, POR EJEMPLO SI EL AMORTIGUADOR (2) SE ESTA APLICANDO POR IGUAL AL DISCO, O SI ESTA EN CONTACTO PERMANENTE DE FROTAMIENTO CON EL DISCO.
