Abstract

Un sistema de frenos, metodo para controlar el sistema de frenos y un vehiculo minero provisto con el mismo. El sistema de frenos (13) del vehiculo minero (2) comprende conjuntos de frenos liberados hidraulicamente y activados por resortes (14) en conexion con ruedas (7) del vehiculo. Los conjuntos de frenos comprenden accionadores de liberacion hidraulicos (RA) los cuales son presurizados para liberar los frenos (15). Durante la operacion normal los accionadores de liberacion son presurizados por medio de un circuito de frenos principal (16) y son controlados por un controlador de frenos (BC). Un circuito de liberacion separado (17) y fuente de presion (Ps2) pueden ser activados para liberar los frenos cuando el vehiculo esta averiado. El sistema comprende ademas un dispositivo de anulacion.
