Abstract

EL SISTEMA DE SUSPENSION INCLUYE DOS AMORTIGUADORES HIDRAULICOS INDEPENDIENTES (10A, 10B) QUE INTERCONECTAN RESPECTIVAS REGIONES REMOTAS DE LA PARTE SUSPENDIDA Y LA PARTE NO SUSPENDIDA DEL VEHICULO. CADA AMORTIGUADOR TIENE UNA VALVULA SOLENOIDE (62A, 62B) PARA INTERCAMBIAR ENTRE UN ESTADO EN EL QUE EL FLUJO DEL LIQUIDO ENTRE LA CAMARA BAJA (40A, 40B) DEL AMORTIGUADOR Y UNA CAMARA DE COMPENSACION ES MENOS RESTRINGIDO Y UN ESTADO EN EL QUE EL FLUJO ES MAS RESTRINGIDO. UN TRANSDUCTOR DE PRESION (50A, 50B) ESTA ASOCIADO CON LA CAMARA ALTA (38A, 38B) DE CADA AMORTIGUADOR (10A, 10B) PARA ACTIVAR LA VALVULA DEL SOLENOIDE DEL ESTADO EN QUE EL FLUJO ES MENOS RESTRINGIDO AL ESTADO EN QUE EL FLUJO ES MAS RESTRINGIDO CUANDO LA PRESION EN LA CAMARA SUPERIOR (38A, 38B) CON LA QUE EL TRANSDUCTOR ESTA ASOCIADO (50A, 50B) EXCEDE UNA PREDETERMINADA CARGA
