Abstract

<B>SENSOR DO LIMITE DO ATUADOR DE FREIO PARA FINS DE MANUTENçãO<D>Um atuador de freio tendo um dispositivo interruptor montado em um alojamento de atuador com uma peça mola parcialmente cercando uma haste de atuador e adaptada para entrar em contato com uma seção de maior diâmetro da haste do atuador quando o desgaste do freio leva o curso da haste do atuador à sua posição limite de manutenção. Durante operação normal, a peça mola está afastada da seção de menor diâmetro da haste do atuador. O dispositivo interruptor é fixado à primeira extremidade da peça mola tendo um primeiro e um segundo contato elétrico que estendem-se e fazem contato elétrico com uma placa condutora fixada na segunda extremidade da peça mola enquanto a haste do atuador de freio não alcançou seu limite de manutenção.
