Abstract

Un sistema de control neumatico automatico para los muelles de aire de un sistema de ejes/suspension tipo viga de remolque de marcha de aire para semi-remolques. Una pluralidad de conductores y valvulas del sistema de control interconectan neumaticamente una o mas fuentes de aire comprimido, los frenos de estacionamiento de vehiculo y los muelles de aire de suspension. El sistema de control incorpora una valvula piloto de dos vias de doble posicion ventilada para controlar la inflacion y deflacion de cada muelles de aire. La valvula cierra cuando las presiones de aire en un par de lineas de sensor del sistema de control difieren, permitiendo asi la completa o casi completa deflacion del muelle de aire que controla antes de que se ponga el freno de estacionamiento, disminuyendo o eliminando por consiguiente los problemas de la caida del remolque y la separacion durante la carga de un remolque vacio, hasta ahora provocados por la completa o casi completa deflacion de los muelles de aire solo despues de que ya se han puesto los frenos de estacionamiento.
