Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE DIRECCION ASISTIDA CON UNA SERVOVALVULA (6) ABIERTA EN EL CENTRO, DISEÑADA PARA SUMINISTRAR A UN ELEMENTO (1) ACTUADOR CON PRESION HIDRAULICA, Y CON UNA BOMBA (7) ACCIONADA POR UN MOTOR (13) ELECTRICO PARA SUMINISTRAR A LA SERVOVALVULA (6) FLUIDO HIDRAULICO, SIENDO CONTROLADO EL CONSUMO DE POTENCIA DEL MOTOR ELECTRICO POR MEDIO DE UNA UNIDAD (21) ELECTRONICA COMO UN RESULTADO DE LA COMPARACION DE LOS PARAMETROS DE FUNCIONAMIENTO MONITORIZADOS MEDIANTE SENSORES. LA INVENCION PROPONE QUE LOS SENSORES SEAN CONECTADOS A UNA UNIDAD DE CONTROL DISPONIENDO AL MENOS DE UN MICROPROCESADOR, DEFINIENDO LA UNIDAD DE CONTROL LOS VALORES DE REFERENCIA COMO UNA FUNCION DE LOS PARAMETROS DE FUNCIONAMIENTO MONITORIZADOS.
