Abstract

UN SISTEMA MULTI-EJE DE SUSPENSION DE AIRE PARA UN VEHICULO BASCULANTE QUE TIENE CERCA DE EL UN EJE TRASERO (7'''''') Y POR LO MENOS OTRO EJE (7'''', 7'') DELANTE DEL EJE TRASERO, SUMINISTRA UN SOBRE-AJUSTE DEL SISTEMA ECUALIZADOR DE CARGA NORMAL ENTRE LOS EJES DURANTE EL BASCULAMIENTO PARA ASI ALIVIAR LOS MOMENTOS PROPIOS DE CURVATURA DEL CHASIS DEL VEHICULO. UNA VALVULA (41) REDUCTORA DE PRESION QUE SE MANIPULA A VOLUNTAD, ESTA EN CIRCUITO CON UNA FUENTE DE PRESION DE AIRE, MUELLES DE AIRE (7C, 8C) DEL EJE TRASERO (7'''''') Y CON PRIMERA Y SEGUNDA VALVULA (23, 32), MANIPULADA SELECTIVAMENTE POR UNA TERCERA VALVULA (39), QUE ESTA EN CIRCUITO CON LOS MUELLES DE AIRE (7C, 8C; 7B, 8B; 7A, 8A) DEL EJE TRASERO (7'''''') Y LOS OTROS EJES (7'''', 7''). LA PUESTA EN MARCHA DE LA PRIMERA Y SEGUNDA VALVULA (23, 32) AISLA LOS MUELLES DE AIRE (7C, 8C) DE POR LO MENOS EL EJE TRASERO (7'''''') DE LOS DEL OTRO EJE O EJES (7'''', 7'') Y CONECTA LA VALVULA REDUCTORA DE PRESION (41) A DICHOS MUELLES (7B, 8B; 7A, 8A) PARA ASI REDUCIR SU PRESION DE AIRE.
