Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Steuerung des Luftdurchsatzes durch eine im Frontbereich eines Kraftfahrzeugs vorgesehene Eintrittsöffnung nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a device for controlling the air flow rate by a provided in the front region of a motor vehicle entrance opening the preamble of claim 1.
Allgemein bekannt sind Luftsteuerklappen, um den Luftdurchsatz durch eine im Frontbereich eines Kraftfahrzeugs vorgesehene Eintrittsöffnung zu steuern. Solche Luftsteuerklappen werden bei Kraftfahrzeugen beispielsweise häufig zur Steuerung eines durch einen aktiv mittels eines Lüfters erzeugten und/oder passiv fahrtwindbedingten Kühlluftstromes verwendet. Der aktiv erzeugte Anteil eines Luftstromes ist dabei auch durch eine entsprechende Steuerung des Lüfters steuerbar, um jedoch den passiven, fahrtwindabhängigen Luftstrom zu steuern, sind Luftsteuerklappen notwendig.Generally Air control flaps are known to the air flow through a to control the entry opening provided in the front area of a motor vehicle. Such air control flaps are in motor vehicles, for example often for controlling a by an active means of a fan generated and / or used passively wind-induced cooling air flow. The actively generated portion of an air flow is also through a corresponding control of the fan controllable, however the passive, wind-dependent To control airflow, air control flaps are necessary.
Die
Steuerung insbesondere der passiven Kühlluftströme bei Kraftfahrzeugen erfolgt
vor dem Hintergrund, einerseits eine ausreichende Kühlung sicherzustellen
und andererseits – wenn
ein Kühlluftstrom
nicht erforderlich ist – den
Luftwiderstand des Fahrzeuges niedrig zu halten. Die
Ein weiteres Anwendungsgebiet von Luftsteuerklappen betrifft die Temperierung von Katalysatoren. Aus der DE-PS 22 22 498 ist dazu bereits der grundlegende Gedanke einer Temperaturregeleinrichtung für einen Abgaskatalysator eines Kraftfahrzeuges mittels einer elektromotorisch betätigten Schwenkklappe bekannt. Insbesondere NOx-Speicherkatalysatoren erreichen ausreichend hohe Konvertierungsraten nur in einem schmalen Abgastemperaturfenster, wodurch der den Wirkungsgrad steigernde Magerbetriebsbereich der Brennkraftmaschine stark begrenzt wird.Another application of air control valves relates to the temperature of catalysts. From DE-PS 22 22 498 is already the basic idea of a temperature control device for an exhaust gas catalyst of a motor vehicle by means of an electric motor operated pivoting flap known. In particular, NO x storage catalysts achieve sufficiently high conversion rates only in a narrow exhaust gas temperature window, whereby the efficiency-increasing lean operating range of the internal combustion engine is greatly limited.
Aufgabe der Erfindung ist es, eine Vorrichtung zur Steuerung des Luftdurchsatzes durch eine im Frontbereich eines Kraftfahrzeugs vorgesehene Eintrittsöffnung zu schaffen, die unempfindlich gegen Verschmutzung ist.task The invention is a device for controlling the air flow by an opening provided in the front area of a motor vehicle create that is insensitive to pollution.
Diese Aufgabe wird mit einer Vorrichtung zur Steuerung des Luftdurchsatzes durch eine im Frontbereich eines Kraftfahrzeugs vorgesehene Eintrittsöffnung mit den Merkmalen des Patentanspruchs 1 gelöst.These Task is with a device for controlling the air flow by an opening provided in the front region of a motor vehicle the features of claim 1.
Erfindungsgemäß ist zur Steuerung des Luftdurchsatzes durch eine im Frontbereich eines Kraftfahrzeugs vorgesehene Eintrittsöffnung in dieser zumindest ein aufblasbares Luftkissen angeordnet, das im nicht aufgeblasenen Zustand die Eintrittsöffnung nicht oder nur geringfügig verkleinert, während es im vollständig aufgeblasenen Zustand die Eintrittsöffnung verschließt. Im Gegensatz zu den aus dem Stand der Technik bekannten Vorrichtungen zur Steuerung des Luftdurchsatzes mittels mehrerer Luftklappen ist die erfindungsgemäße Vorrichtung auch bei starker Verschmutzung voll funktionsfähig. Während die bekannten Luftklappensysteme zudem während des Winters dazu neigen zu vereisen, ist die erfindungsgemäße Vorrichtung auch gegen Vereisungen sehr unempfindlich. Insgesamt weist die erfindungsgemäße Vorrichtung gegenüber dem Stand der Technik weniger einzelne mechanische Bauteile auf, sodass die Herstellkosten und das Gewicht gegenüber dem Stand der Technik geringer sind.According to the invention is for Control of the air flow through one in the front of a motor vehicle provided inlet opening in this at least one inflatable air cushion arranged in the not inflated state, the inlet opening is not or only slightly reduced, while it in complete inflated state closes the inlet opening. In contrast to the known from the prior art devices for control the air flow rate by means of several louvers is the device according to the invention also Fully functional if heavily soiled. While the known air flap systems also during Winters tend to ice, is the device of the invention also very resistant to icing. Overall, the device according to the invention across from the prior art less individual mechanical components, so that the manufacturing costs and the weight compared to the prior art lower are.
Durch die Schließung des Lufteintritts unmittelbar an der Eintrittsöffnung kann der aerodynamische Cx-Luftwiderstandswert des Kraftfahrzeugs bei geschlossener Eintrittsöffnung verringert werden. In der Folge resultiert daraus eine Verringerung des CO2-Ausstoßes des Kraftfahrzeugs.By closing the air inlet directly at the inlet opening, the aerodynamic C x air resistance value of the motor vehicle can be reduced when the inlet opening is closed. As a result, this results in a reduction in the CO 2 emissions of the motor vehicle.
Bevorzugt ist das Luftkissen schlauchförmig gestaltet. Günstigerweise sind in der Eintrittsöffnung mehrere schlauchförmige Luftkissen nebeneinander angeordnet, die sich im aufgeblasenen Zustand aneinander abstützen. Diese schlauchförmigen Luftkissen sind vorfeilhafterweise vom Fahrzeugäußeren aus gesehen unmittelbar hinter einem Ziersteg in der Eintrittsöffnung angeordnet, sodass die Luftkissen im nicht aufgeblasenen Zustand optisch zumindest größtenteils verdeckt sind. Günstigerweise sind die Zierstege jeweils mit einem schlauchförmigen Luftkissen verbunden und bestimmen so die Lage des Luftkissens.Prefers the air cushion is tubular. conveniently, are several in the entrance opening tubular Air cushions arranged side by side, which are inflated support each other. This tubular Luftkissen are vorfeilhafterweise seen from the vehicle exterior directly placed behind a decorative strip in the entrance opening, so that the Air cushion in the non-inflated state optically at least for the most part are covered. conveniently, the decorative webs are each connected to a tubular air cushion and thus determine the position of the air cushion.
Die erfindungsgemäße Vorrichtung kann zur Steuerung des Luftdurchsatzes in einer Eintrittsöffnung für Kühlluft für eine Brennkraftmaschine des Kraftfahrzeugs eingesetzt werden. Bevorzugt erfolgt die Steuerung des Luftdurchsatzes dann in Abhängigkeit der Kühlmitteltemperatur der Brennkraftmaschine, der Fahrzeuggeschwindigkeit, eines Klimaanlagendruckes und/oder in Abhängigkeit der Abgastemperatur der Brennkraftmaschine. Der Füllgrad des oder der Luftkissen wird dabei entsprechend dieser Messgrößen gesteuert.The inventive device can for controlling the air flow in an inlet opening for cooling air for an internal combustion engine be used of the motor vehicle. Preferably, the control takes place the air flow then depending the coolant temperature the internal combustion engine, the vehicle speed, an air conditioning pressure and / or depending the exhaust gas temperature of the internal combustion engine. The degree of filling of the or the air cushion is controlled according to these parameters.
Weitere vorteilhafte Ausgestaltungen sind Gegenstand von Unteransprüchen.Further advantageous embodiments are the subject of dependent claims.
