Abstract

EN UN SISTEMA DE SUSPENSION POR AIRE DE UN VEHICULO LA ALTURA DE LA PLATAFORMA DEL VEHICULO SE MANTIENE, CUANDO ESTA EN USO, POR VALVULAS DE CONTROL DE ALTURA (6, 7). PARA FACILITAR LA CARGA, EL OPERADOR PUEDE AJUSTAR LA ALTURA PARA ANULAR LA VALVULA DE CONTROL DE ALTURA POR MEDIO DE UNA VALVULA SELECTORA (8). LA ALTURA PUEDE ENTONCES AJUSTARSE MEDIANTE UNA VALVULA DE ELEVACION / DESCENSO (5). SI EL OPERADOR NO DEVUELVE EL CONTROL A LA VALVULA SELECTORA Y / O NO PONE LA VALVULA DE ELEVACION / DESCENSO EN SU CONDICION NORMAL, LA VALVULA SELECTORA VUELVE A SU CONDICION NORMAL MEDIANTE UNA LINEA AUXILIAR (43) CONECTADA A LA LINEA DEL FRENO DE FORMA QUE EL VEHICULO VUELVA AUTOMATICAMENTE A LA ALTURA NORMAL DE CONDUCCION LA PRIMERA VEZ QUE SE USE EL FRENO. ALTERNATIVAMENTE, LA VALVULA (8) PUEDE HACER FUNCIONAR MEDIANTE UN SOLENOIDE CONECTADO AL CIRCUITO DE LA LUZ DEL FRENO DE FORMA QUE NO SE AFECTE AL CIRCUITO DE FRENOS. EN UNA DISPOSICION ALTERNATIVA, LA ALTURA DEL SISTEMA DE SUSPENSION SE AJUSTA MEDIANTE DOS VALVULAS DE RESORTE MANUALMENTE OPERABLES. DE NUEVO, UNA VALVULA SELECTORA DEVUELVE LA ALTURA A UNA CONDICION NORMAL DE CONDUCCION LA PRIMERA VEZ QUE SE HAGA USO DEL FRENO.
