Abstract

Un sistema combinado de detección de desgaste de zapatas de freno y de nivel de fluido, que comprende un freno (10) dotado de una zapata de freno (16) y de una superficie de frenado conductora (12), acoplándose dichas zapata (16) y superficie (12) durante el frenado por la acción de un sistema de freno accionado por fluido (1) siendo suministrado dicho fluido desde un depósito de fluido de frenos (27), un lazo sensor (18) embebido en la zapata de freno (16) y colocado de forma que resulte roto cuando el desgaste de dicha zapata (16) rebase el límite de trabajo, medios indicadores (40) y medios detectores (32, 34) que accionan dichos medios indicadores (40) al romperse el lazo sensor (18), caracterizado además por ir dotado de un medio interruptor (24) conectado en serie con el lazo sensor (18) y accionado por un flotador (25) instalado en el depósito de fluido de frenos (27), cuyo medio interruptor (24) se halla en un primer estado cuando el fluido está por encima de un nivel predeterminado, y en un segundo estado cuando se encuentra por debajo de dicho nivel predeterminado, accionado también los medios detectores (32, 34) a los medios indicadores (40) cuando el interruptor (24) se halla en dicho segundo estado.
