Abstract

UN APARATO DE SERVODIRECCION ASISTIDO HIDRAULICAMENTE (10) SOMETIDO A UN CAMBIO DEL ESFUERZO DIRECCION DEBIDO A UN CAMBIO DE TEMPERATURA SE COMPENSA PARA QUE DE UNA RESPUESTA CONSISTENTE A TODAS LAS TEMPERATURAS. HAY UNA VALVULA DE CONTROL HIDRAULICA (16) ACOPLADA A UN DISPOSITIVO ELECTROMAGNETICO (92) QUE CONTROLA EL ESFUERZO DE DIRECCION COMO UNA FUNCION DE CORRIENTE DE ENERGIZACION. LA CORRIENTE SE AJUSTA SEGUN LA TEMPERATURA PARA COMPENSAR LOS CAMBIOS DE TEMPERATURA. UNA UNIDAD DE CONTROL DE MICROORDENADOR (178) ALMACENA DATOS EMPIRICOS REFERENTES AL EFECTO DE LA TEMPERATURA EN EL ESFUERZO DE DIRECCION Y CALCULA EL AJUSTE DE CORRIENTE NECESARIO PARA CUALQUIER TEMPERATURA DEL APARATO MEDIDA. EN UNA PUESTA EN PRACTICA DE LA INVENCION, LA TEMPERATURA NO SE MIDE DIRECTAMENTE SINO QUE SE DERIVA DE LA DESVIACION DE LA CORRIENTE DE ENERGIZACION DE LA CORRIENTE DESEADA TEORETICA, CUYA DESVIACION ES UNA FUNCION DE TEMPERATURA. EL EFECTO DE LAS VARIACIONES DE TENSION TAMBIEN SE COMPENSA.
