Abstract
"FREIO DE TAMBOR" Dentro de um cilindro da roda, um pistão de acionamento e um pistão de controle, as extremidades de base das quais recebe uma pressão hidráulica proveniente de um cilindro principal, são opostamente dispostos enquanto são axialmente alinhados um com o outro. Uma sapata primária é pressionada pelo pistão de acionamento, e uma saída de força de reação de ancoragem proveniente de uma sapata secundária é distribuída para e carregada em uma parte de ancoragem e no pistão de controle através de uma alavanca de controle. Quando a força de reação de ancoragem atinge um valor predeterminado de força ou superior, um mecanismo de conexão de controle de força de reação de ancoragem opera para mover a sapata primária para longe de um tambor de freio, verificando dessa forma o aumento da força de reação de ancoragem.
