Description

Die Erfindung betrifft eine Verbindung eines geräuschdämpfenden Ver­ kleidungsteiles nach dem Oberbegriff des Anspruchs 1.The invention relates to a connection of a noise-damping Ver clothing part according to the preamble of claim 1.

Eine derartige Befestigung eines Verkleidungsteiles ist durch die DE 36 04 289 A1 bekannt.Such attachment of a trim part is known from DE 36 04 289 A1.

Die DE 34 02 731 A1 offenbart ein geräuschdämmendes front­ seitig angeordnetes Verkleidungsteil, welches hakenförmig an eine obere Stoßfängerkante anschließt. Der dabei zum Motor hinweisende Haken ist ohne Selbstsicherung ausgeführt und daher nachgiebig gegenüber Windkräften.DE 34 02 731 A1 discloses a noise-reducing front side panel, which is hook-shaped an upper bumper edge connects. The one to the engine indicative hook is executed without self-locking and therefore compliant to wind forces.

Aufgabe der Erfindung ist es, die gattungsgemäße Verbindung in der Weise weiterzubilden, daß sie einfach und schnell zu montieren- bzw. demontieren ist und gleichzeitig Windkräften besser standhält.The object of the invention is the generic connection in the way that they can easily and quickly assemble or disassemble and at the same time wind forces withstands better.

Die erfindungsgemäße Lösung dieser Aufgabe ist in den Merkmalen nach dem Kennzeichen des Patentanspruches 1 zu sehen.The achievement of this task is in the features of to see the character of claim 1.

Die Erfindung ist anhand eines Ausführungsbeispieles nachstehend erläu­ tert. Die zugehörige Zeichnung zeigt inThe invention is explained below using an exemplary embodiment tert. The associated drawing shows in

Fig. 1 eine Ansicht eines Kraftfahrzeug-Motorraumes mit einem daran anzusetzenden Verkleidungsteil und Fig. 1 is a view of a motor vehicle engine compartment with a trim part to be attached and

Fig. 2 eine Schnittdarstellung gemäß Linie II-II einer der in Fahr­ zeuglängsrichtung gesehen vorderen Verbindungsstellen. Fig. 2 is a sectional view according to line II-II of one of the front connecting points seen in the longitudinal direction of the vehicle.

In Fig. 1 ist in einer perspektivischen Teilansicht eines Kraftfahrzeu­ ges 1 dessen Motorraum 2 mit diversen Einbauaggregaten erkennbar. Ein formstabiles geräuschdämpfendes Verkleidungsteil 3 mit seinem für diese Zwecke üblichen strukturellen Aufbau ist an seinem in Fahrzeuglängs­ richtung gesehen hinteren Endabschnitt 4 mit einer Anzahl von Durch­ brechungen 5 für die Aufnahme von hier nicht gezeigten Befestigungs­ schrauben ausgestattet, die in entsprechende Aufnahmen 6 eines Quer­ trägers 7 einschraubbar sind, welcher an einem Hilfsrahmen 8 befestigt ist.In Fig. 1 is a partial perspective view of a motor vehicle ges 1 whose engine compartment 2 can be seen with various installation units. A dimensionally stable noise-damping trim part 3 with its usual structural design for this purpose is equipped at its rear end section 4 , seen in the longitudinal direction of the vehicle, with a number of openings 5 for receiving fastening screws, not shown here, which fit into corresponding receptacles 6 of a cross member 7 are screwed, which is attached to an auxiliary frame 8 .

Das Verkleidungsteil 3 ist darüberhinaus mit einem Durchbruch 9 ausge­ stattet, aus dem sehr weit nach unten hervorstehende Einbauaggregate, wie beispielsweise eine Ölwanne 10, zumindest teilweise hindurchtreten können.The trim part 3 is also equipped with an opening 9 , from which very far downwardly protruding installation units, such as an oil pan 10 , can at least partially pass through.

Für die Anbindung des Verkleidungsteiles 3 mit seinem vorderen Endab­ schnitt 13 an einem nach hinten reichenden Stoßfängerüberzug 14 des Stoßfängers 15 sind über die Länge des vorderen Endabschnittes 13 in gleichen Abständen eine Anzahl von höckerförmigen Ausformungen 16 mit Querschlitzen 17 angeordnet, die eine rechteckige Grundform auf­ weisen.For the connection of the trim part 3 with its front Endab section 13 to a rear-facing bumper cover 14 of the bumper 15 over the length of the front end portion 13 a number of bump-shaped formations 16 with transverse slots 17 are arranged, which have a rectangular basic shape .

Ihnen zugeordnet sind auf der Innenfläche des Stoßfängerüberzuges 14 aufgesetzte Fanghaken 18, die jeweils zumindest mit ihrem hakenförmigen hinteren Ende 19 eine etwas geringere Breite aufweisen als die Quer­ schlitze 17 der höckerförmigen Ausformungen 16.They are assigned on the inner surface of the bumper cover 14 attached catch hooks 18 , each of which, at least with its hook-shaped rear end 19, has a somewhat smaller width than the transverse slots 17 of the hump-shaped formations 16 .

Die Montage des Verkleidungsteiles 3 geschieht nun in der Weise, daß es (in Fahrzeuglängsrichtung) von hinten nach vorne und ggf. mit einer gewissen Schrägstellung in Richtung auf die Fanghaken 18 bewegt und dabei in zwischen den hakenförmigen Enden 19 und dem Stoßfängerüberzug 14 gebildete Öffnungen 20 hineingeschoben wird. Jedes hakenförmige und elastisch nachgebende (Biegebeanspruchung des Fanghakens 18) Ende 19 gleitet dabei an der Oberfläche der höckerförmigen Ausformung 16 ent­ lang, bis es in den Querschlitz 17 einrastet, so daß dadurch eine selbstsichernde Hakenverbindung entsteht. Anschließend kann der hintere Endabschnitt 4 des Verkleidungsteiles 3 am Querträger 7 angeschraubt werden. Der vordere Endabschnitt 13 liegt auf der dem Motorraum 2 zugewandten Oberfläche 21 des Stoßfängerüberzuges 14 auf. Zum Zweck der Demontage wird nach Lösen der Schraubverbindungen das Verkleidungsteil 3 etwas nach vorne bewegt, wonach dann die hakenförmigen Enden 19 der Fanghaken 18 leicht nach oben aus den Querschlitzen 17 herausgedrückt und das Verkleidungsteil 3 durch anschließendes Bewegen nach hinten ab­ genommen werden kann.The trim part 3 is now assembled in such a way that it moves (in the vehicle longitudinal direction) from the rear to the front and possibly with a certain inclination in the direction of the catch hooks 18 and thereby in openings 20 formed between the hook-shaped ends 19 and the bumper cover 14 is pushed in. Each hook-shaped and elastically yielding (bending stress of the catch hook 18 ) end 19 slides ent on the surface of the hump-shaped formation 16 ent long until it engages in the transverse slot 17 , so that this creates a self-locking hook connection. The rear end section 4 of the trim part 3 can then be screwed onto the cross member 7 . The front end section 13 lies on the surface 21 of the bumper cover 14 facing the engine compartment 2 . For the purpose of disassembly, the cover part 3 is moved slightly forward after loosening the screw connections, after which the hook-shaped ends 19 of the catch hook 18 are pushed out slightly upward from the transverse slots 17 and the cover part 3 can be removed by subsequent movement backwards.
