Abstract

UNA SUSPENSION NEUMATICA PARA UN VEHICULO QUE TIENE UN ELEMENTO DE CONTROL QUE INCLUYE UNA ECU (27) Y UN BLOQUE DE VALVULAS (28) CONECTADO DE FORMA OPERATIVA A UNOS RESORTES NEUMATICOS (15, 16, 17, 18) PARA MANTENER LA ALTURA DE CONDUCCION ENTRE LAS PARTES ARMADAS CON RESORTE Y NO ARMADAS CON RESORTE DEL VEHICULO ADYACENTE A CADA RESORTE NEUMATICO SEGUN UN REGLAJE PARTICULAR. EL ELEMENTO DE CONTROL GENERA PARA CADA RESORTE NEUMATICO UNA SEÑAL DE SUBIDA RESPECTIVA QUE TIENDE A AUMENTAR LA ALTURA DE CONDUCCION Y UNA SEÑAL DE BAJADA RESPECTIVA QUE TIENE A REDUCIR LA ALTURA DE CONDUCCION. SI EL VEHICULO QUEDA PARCIALMENTE SOPORTADO POR UN CONTACTO DIRECTO ENTRE EL CHASIS (21) Y EL SUELO (PANZA AFUERA), ESTO SE DETECTA CONTROLANDO LAS SEÑALES DE LA ECU A LAS VALVULAS DE CONTROL DE LA ALTURA DE CONDUCCION DEL BLOQUE DE VALVULAS. SI SALE UNA SEÑAL DE BAJADA DURANTE MAS DE UN PERIODO DE TIEMPO PREDETERMINADO, LA SEÑAL DE BAJADA CESA Y SE RESTAURAN LAS CONDICIONES NORMALES REINFLANDO Y EQUILIBRANDODE FORMA CONTROLADA LOS RESORTES NEUMATICOS.
