Luftleitköfper für ein KraftfahrzeugAir guide body for a motor vehicle
An mehreren Stellen eines Kraftfahrzeuges sind Luftleitbleche erforderlich, um Strömungsverluste gering zu halten oder ein unerwünschtes Umströmen zu verhindern. Beispielsweise ist ein solches Leitblech zwischen dem Kühler und der Karosserie von Vorteil für die Kühlleistung des Kühlers. Auch Lüftungsklappen für Luftaus- oder -eintritte sollen im allgemeinen relativ dicht verschliessen um Luftzug an unerwünschten Stellen zu vermeiden. Ein anderes Anwendungsbeispiel solcher Leitbleche sind Lampenfassungen.There are air baffles at several points on a motor vehicle required to keep flow losses low or to prevent unwanted flow around. For example such a baffle between the radiator and the body is advantageous for the cooling performance of the radiator. Ventilation flaps for air outlets or inlets should also generally close relatively tightly to prevent unwanted drafts Avoid bodies. Another application example of such baffles are lamp sockets.
Solche Leitbleche überbrücken häufig Oeffnungen oder Spalte, deren Abmessungen nicht genau eingehalten werden können. Um aufwendige Anpassarbeiten zu vermeiden, hat man in solchen Fällen schon vorgeschlagen, am Blechrand eine elastomereSuch baffles often bridge openings or gaps, the dimensions of which cannot be precisely adhered to. In order to avoid time-consuming adjustment work, it has already been proposed in such cases to use an elastomeric one on the edge of the sheet metal

Dichtlippe anzukleben. An Lüftungsklappen wird zürn Abdichten oft am Rand ein Schaumgummistreifen aufgeklebt. Diese Bauteile sind dadurch relativ aufwendig in der Herstellung. Zudem hält der Klebstoff selten über die ganze Lebensdauer des Fahrzeuges den klimatischen Äenderungen und der Belastung stand, sodass entweder der Bauteil vorzeitig ausgewechselt werden muss oder seine Funktion nur noch unbefriedigend erfüllen kann.Glue the sealing lip. The ventilation flaps are tightly sealed often a foam rubber strip is glued to the edge. As a result, these components are relatively expensive to manufacture. In addition, the adhesive seldom withstands climatic changes and stress over the entire service life of the vehicle so that either the component has to be replaced prematurely or its function is only unsatisfactory can.
Die Neuerung bezweckt, diese Nachteile des bekannten Standes der Technik zu beseitigen. Diese Aufgabe wird mit einem Luftleitkörper gemäss Anspruch 1 gelöst.The aim of the innovation is to eliminate these disadvantages of the known prior art. This task is done with an air deflector solved according to claim 1.
Durch die Materialwahl des Formteils und der Dichtlippe lässt sich der Luftleitkörper in einem Arbeitsgang spritzgiessen, was niedrige Herstellungskosten ergibt. Dichtlippe und Formteil sind dabei an der Stossstelle miteinander verschmolzen, was eine zuverlässige, dauerhafte Verbindung der beiden Teile gewährleistet·Due to the choice of material for the molded part and the sealing lip, the air guide body can be injection molded in one operation, resulting in low manufacturing costs. The sealing lip and molded part are fused together at the joint, which ensures a reliable, permanent connection of the two parts
Durch die vorzügliche Verbindung ist es auch möglich, flache Teile miteinander stumpf zu verbinden, wie dies Anspruch 2 vorschlägt. Dies ergibt eine sehr flache Bauweise.Due to the excellent connection, it is also possible to butt-connect flat parts to one another, as claimed in claim 2 suggests. This results in a very flat design.
Es ist an sich bekannt, bei Sanitärrohren eine elastomere Dichtung in einem Arbeitsgang im Spritzgiessverfahren anzu-It is known per se to apply an elastomeric seal to sanitary pipes in one operation using the injection molding process.

bringen. Bei solchen Röhren sind allerdings" die Kontaktflächen wesentlich grosser und die Dichtung ist erheblich geringeren thermischen und mechanischen Beanspruchungen ausgesetzt. bring. In such tubes, however, "the contact surfaces significantly larger and the seal is exposed to significantly lower thermal and mechanical stresses.
Nachfolgend wird ein Ausführungsbeispiel der Neuerung anhand beiliegender Zeichnung erläutert.An exemplary embodiment of the innovation is explained below with reference to the accompanying drawing.
Ein aus einem thermoplastischen/ harten Kunststoff bestehender Formteil ist mit einer elastomeren Dichtlippe 2 versehen und überbrückt beispielsweise einen Spalt zwischen dem Karosserie-Frontblech 5 und dem Kühler 6. Die Dichtlippe 2 gleicht dabei die Einbautoleranz des Kühlers 6 gegenüber dem Frontblech 5 aus. Der Formteil 1 ist am Frontblech 5 z.B. durch angedeutete Schrauben 4 befestigt.A molded part made of a thermoplastic / hard plastic is provided with an elastomer sealing lip 2 and bridges, for example, a gap between the body front panel 5 and the radiator 6. The sealing lip 2 compensates for the installation tolerance of the cooler 6 with respect to the front panel 5. The molded part 1 is attached to the front sheet 5 e.g. fastened by indicated screws 4.
Der Formteil 1 und die Dichtlippe 2 werden gemeinsam und gleichzeitig spritzgegossen.. An der Stossstelle 3 verschmelzen dabei die beiden unterschiedlichen Materialien miteinander. The molded part 1 and the sealing lip 2 are injection molded together and at the same time the two different materials with each other.
Als Material für den Formteil 1 eignet sich beispielsweise glasfaserverstärktes Polypropylen in Verbindung mit Polypropylen mit einem Weichmacher als Material für die Dichtlippe. Weitere vorteilhafte Materialkombinationen sind in den Ansprüchen 4-6 umschrieben.A suitable material for the molded part 1 is, for example, glass fiber reinforced polypropylene in conjunction with polypropylene with a plasticizer as the material for the sealing lip. Further advantageous material combinations are in the Claims 4-6 circumscribed.
