Abstract
Description
Die Erfindung betrifft ein großflächiges Karosserieteil, insbesondere eine Motorhaube oder eine Fronthaube gemäß den Merkmalen des Patentanspruchs 1.The Invention relates to a large-scale body part, in particular a bonnet or a bonnet according to the features of claim 1
Um die Schwere von Verletzungen, insbesondere Kopfverletzungen, bei Fußgängern und anderen Aufprallbeteiligten zu reduzieren, sind im Serienfahrzeugbau Motorhauben oder Fronthauben üblich, die in bestimmten Bereichen, vorzugsweise in Kopfaufprallbereichen, aufpralldämpfend ausgelegt. Dazu sind die Motorhauben so gestaltet, dass die Aufprallenergie, die beim Aufprall aufgenommen werden soll, durch Deformation der Motorhaube abgebaut werden kann. Die Intrusionstiefe der Motorhaube darf dabei ein bestimmtes Maß nicht übersteigen, um Kontakt mit unterhalb der Motorhaube angeordneten Antriebsaggregaten zu vermeiden.Around the severity of injuries, especially head injuries Pedestrians and To reduce other impact participants are in production vehicles Hoods or Bonnets usual, in certain areas, preferably in head impact areas, impact damping designed. These hoods are designed so that the impact energy, which is to be absorbed by the impact, by deformation of the Bonnet can be removed. The intrusion depth of the hood may not exceed a certain amount, for contact with below the hood arranged drive units to avoid.
Die
Aufgrund der kompakten Anordnung von Antriebsaggregaten direkt unterhalb der Motorhaube und den beengten Bauraumverhältnissen im Motorraum müssen spezielle Kühlmaßnahmen, wie beispielsweise Abschirmbleche oder Materialumstellungen, für die Aggregate, aber auch für den Getriebetunnel geschaffen werden, die gewichts- und kostenintensiv sind.by virtue of the compact arrangement of drive units directly below the bonnet and the cramped space conditions in the engine compartment must be special Cooling measures such as shielding plates or material changes, for the aggregates, but also for To create the transmission tunnel, the weight and cost-intensive are.
Es besteht daher die Aufgabe der Erfindung darin, ein großflächiges Karosserieteil, insbesondere eine Motorhaube oder eine Fronthaube zu schaffen, die die Luftkühlung innerhalb des Motorraums verbessert bzw. unterstützt.It Therefore, the object of the invention is to provide a large-scale body part, in particular to provide a bonnet or a bonnet, the the air cooling improved or supported within the engine compartment.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The Task is according to the invention with the features of claim 1. Advantageous embodiments emerge from the subclaims.
Das erfindungsgemäße großflächige Karosserieteil zeichnet sich insbesondere dadurch aus, dass die Luftführung in die Motorhaube integriert ist. Unter Berücksichtigung des Fußgängerschutzes ist das Innenprofil mit der Außenbeplankung so verbunden, dass die gebildeten Hohlräume als dichter Strömungskanal ausgebildet sind. Dazu sind Bereiche des Innenprofils mit Bereichen der Außenbeplankung vorzugsweise flächig verklebt oder verschweißt, so dass ein dichter Strömungskanal entstehen kann. Das Innenprofil besteht aus einer relativ dünnen dreidimensionalen Blechgeometrie, welche gezielt Energie im Falle eines Kopfaufpralls durch Deformation aufnehmen kann. Die gebildeten Hohlräume werden so angeordnet, dass der geförderte Luftstrom zwischen Innenprofil und Außenbeplankung von einem -in Fahrtrichtung gesehenen- vorderen Bereich bis in einen hinteren Bereich des Motorraums gelangen kann. Folgende Vorteile ergeben sich aus dem erfindungsgemäßen großflächigen Karosserieteil: Da das Innenprofil zur Bildung eines Luftströmungskanals genutzt wird, können zusätzliche Bauteile, die der Luftführung dienen, entfallen. Es handelt sich bei der erfindungsgemäßen Lösung um eine passive, dass heißt, geschwindigkeitsabhängige Luftführung, in die die Fußgängerschutzfunktion integriert ist. Durch die ohnehin an Außenbeplankung und Innenprofil vorhandenen glatten Flächen, beispielsweise lackiertes Blech, entstehen nur geringe Strömungsverluste. Aufgrund des guten Strömungsverhaltens braucht die Luft nicht vorgewärmt werden. Der notwendige Staudruck wird durch vorhandene Bauteile, wie beispielsweise eine Hutze für die Rohluftansaugung, erzeugt.The inventive large-scale body part is characterized in particular by the fact that the air flow in the bonnet is integrated. Taking into account the pedestrian protection is the inner profile with the outer planking connected so that the cavities formed as a dense flow channel are formed. These are areas of the interior profile with areas the outer skin preferably flat glued or welded, leaving a dense flow channel can arise. The inner profile consists of a relatively thin three-dimensional Sheet metal geometry, which specifically energy in the event of a head impact can absorb by deformation. The cavities formed become like this arranged that the sponsored Air flow between inner profile and outer planking of a -in Seen direction of travel - front area to a rear Area of the engine compartment can get. The following advantages result from the large body part according to the invention: Since the inner profile is used to form an air flow channel, additional Components, the air duct serve, omitted. It is in the inventive solution to a passive, that is, speed-sensitive Air duct, in the pedestrian protection function is integrated. By anyway on exterior planking and inner profile existing smooth surfaces, For example, painted metal sheet, only small flow losses. by virtue of good flow behavior does not need the air preheated become. The necessary back pressure is created by existing components, such as a scoop for the Rohluftansaugung generated.
Vorzugsweise kann der Strömungskanal einen im – in Fahrrichtung gesehenen – vorderen Bereich der Motorhaube angeordneten Einlass aufweisen, um ein Einströmen in den Strömungskanal zu ermöglichen.Preferably can the flow channel an im - in Seen direction of travel - front Area of the hood have arranged inlet to flow into the flow channel to enable.
Wenn der Einlass als Luftsammeldüse ausgebildet ist, kann der Staudruck mit zunehmender Fahrgeschwindigkeit erhöht und der Luftstrom weiter nach hinten transportiert werden.If the inlet as Luftsammeldüse is formed, the back pressure with increasing travel speed elevated and the airflow is transported further to the rear.
In einer bevorzugten Ausführungsform ist die Luftsammeldüse im Bereich eines Kühlerquerträgers der Fahrzeugkarosserie angeordnet.In a preferred embodiment is the air collection nozzle in the area of a radiator cross member of Vehicle body arranged.
Ein – in Fahrtrichtung gesehenen – im hinteren Bereich der Motorhaube angeordneter Auslass des Strömungskanals ermöglicht das Versorgen von Aggregaten, die im hinteren Motorraum angeordnet sind, mit Kühlluft.One - in the direction of travel seen in the rear portion of the hood arranged outlet of the flow channel allows supplying aggregates located in the rear engine compartment, with cooling air.
Vorteilhafterweise kann der Auslass als Düse ausgebildet und auf die im Motorraum angeordneten Motoraggregate oder auf den Getriebetunnel ausgerichtet sein.advantageously, can the outlet as a nozzle trained and arranged in the engine compartment engine units or geared to the transmission tunnel.
Weitere vorteilhafte Ausgestaltungen der Erfindung werden im Folgenden anhand der Zeichnung näher erläutert. Dabei zeigen:Further advantageous embodiments of the invention will be described below closer to the drawing explained. Showing:
