Abstract
Description
Die Erfindung betrifft eine Unterbodenverkleidung für den Motorraum eines Kraftfahrzeugs, mit einem Grundkörper aus einem Kunststoffmaterial. Des weiteren betrifft die Erfindung ein Verfahren zur Herstellung einer Unterbodenverkleidung für den Motorraum eines Kraftfahrzeugs.The The invention relates to an underbody panel for the engine compartment a motor vehicle, with a base body made of a plastic material. Of Furthermore, the invention relates to a method for producing a Underbody covering for the engine compartment of a motor vehicle.
Aufgrund der steigenden Anforderungen hinsichtlich der Geräusche im Innenraum von Kraftfahrzeugen wird der Motorraum eines Kraftfahrzeugs immer häufiger nicht nur an seiner Oberseite mittels einer Kunststoffabdeckung und mittels in der Motorhaube angebrachtem Dämmmaterial gegenüber Geräuschen gedämpft, sondern es werden häufig auch Verkleidungen unterhalb des Motorraums angebracht, die dann als Unterbodenverkleidung bezeichnet werden. Diese Unterbodenverkleidungen haben jedoch nicht nur die Aufgabe, den Motorraum möglichst gut gegen die Umgebung abzukapseln, sondern sie haben auch aerodynamische Aufgaben und sollen den Motor und dessen Anbauteile gegenüber äußeren Einflüssen, wie beispielsweise Steinschlag oder dergleichen, und die dadurch entstehenden Korrosionsprobleme schützen.by virtue of the increasing demands regarding the noise in the interior of motor vehicles, the engine compartment of a motor vehicle more often not only on its top by means of a Plastic cover and by means mounted in the hood insulating material but dampened against noise There are often also panels below the engine compartment attached, which are then referred to as underbody paneling. However, these underbody linings are not just the job to encapsulate the engine compartment as well as possible against the environment but they also have aerodynamic tasks and should be the engine and its attachments to outer Influences, such as rockfall or the like, and protect the resulting corrosion problems.
Aus dem allgemeinen Stand der Technik sind hierzu Unterbodenverkleidungen in Form von plattenförmigen Kunststoffteilen bekannt, die Luftleitsysteme und Versteifungsrippen aufweisen und häufig mit Glasfasern verstärkt sind. Zur Geräuschdämmung werden teilweise Volumenkörper mit Luftfüllung oder aufgeschweißte, separate Dämpfungssysteme eingesetzt. Der Nachteil dieser bekannten Verkleidungen ist jedoch der recht komplizierte Aufbau, die insbesondere im Hinblick auf die Verwendung von Glasfasern teuren Materialien und die hohen Herstellungskosten.Out The general state of the art for this purpose are underbody panels known in the form of plate-shaped plastic parts, the Have air control systems and stiffening ribs and often with Glass fibers are reinforced. For noise reduction become partially solid with air filling or welded, separate damping systems used. The disadvantage of these known panels, however the quite complicated structure, in particular with regard to the use of fiberglass expensive materials and the high production costs.

Es ist Aufgabe der vorliegenden Erfindung, eine Unterbodenverkleidung für den Motorraum eines Kraftfahrzeugs zu schaffen, welche in der Lage ist, den Motorraum nach außen und innen akustisch zu isolieren und den sich im Motorraum befindlichen Motor samt seiner Anbauteile gegen äußere Einflüsse zu schützen.It Object of the present invention, an underbody paneling for the engine compartment of a motor vehicle to create which is able to acoustical the engine compartment to the outside and inside isolate and located in the engine compartment engine including his Attachments against external influences too protect.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention This object is achieved by the features mentioned in claim 1.
Das erfindungsgemäße, an dem Grundkörper der Unterbodenverkleidung angebrachte Schallabsorberelement sorgt für eine Schalldämmung des Motorraums gegenüber der Umgebung, so dass im Motorraum hauptsächlich durch die sich darin befindlichem Brennkraftmaschine entstehende Geräusche nicht nach außen bzw. in den Innenraum des Kraftfahrzeugs gelangen können. Hierbei wird eine Beschädigung des Schallabsorberelements durch die oberhalb desselben in Richtung des Motorraums angeordnete flüssigkeitsabweisende Schicht verhindert, da diese die aus dem Motorraum auf die Unterbodenverkleidung auftreffende Flüssigkeit abweist. Die Geräuschentwicklung wird des weiteren durch die an der dem Motorraum abgewandten Unterseite des Grundkörpers angeordnete schallabsorbierende Schicht reduziert. Insgesamt ergibt sich somit eine Unterbodenverkleidung, die erheblich zu einer Geräuschdämmung sowohl in der Umgebung als auch im Innenraum des Kraftfahrzeugs beiträgt.The according to the invention, on the base body the underbody paneling attached sound absorbing element provides for a sound insulation of the engine compartment opposite the environment, so in the engine compartment mainly by the noise of the internal combustion engine is not come to the outside or in the interior of the motor vehicle can. This will damage the sound absorber element by the above the same in the direction of the engine compartment arranged Liquid-repellent layer prevents, since these are the from the engine compartment on the underbody paneling incident fluid rejects. The noise is further by the on the underside of the main body facing away from the engine compartment arranged sound-absorbing layer reduced. Total results thus a subfloor lining, which significantly reduces noise both in the environment and in the interior of the motor vehicle contributes.
Besonders gute Schallabsorptionseigenschaften ergeben sich, wenn das Schallabsorberelement aus PES besteht.Especially good sound absorption properties arise when the sound absorber element consists of PES.
Eine verfahrensgemäße Lösung der Aufgabe ergibt sich durch die Merkmale von Anspruch 10.A procedural solution to the problem results by the features of claim 10.
Durch das erfindungsgemäße Verfahren kann die oben beschriebene Unterbodenverkleidung auf besonders einfache und ökonomische Art und Weise hergestellt werden, wobei das wenigstens eine Schallabsorberelement in die flüssigkeitsabweisende Schicht integriert und auf der gegenüberliegende Seite durch die schallabsorbierende Schicht gekapselt ist.By the process according to the invention may be as described above Underbody paneling on a particularly simple and economical Be prepared manner, wherein the at least one sound absorbing element integrated in the liquid-repellent layer and on the opposite side through the sound-absorbing Encapsulated layer.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den restlichen Unteransprüchen. Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig beschrieben.Further advantageous embodiments and modifications of the invention will become apparent from the remaining subclaims. Hereinafter, an embodiment the invention in principle with reference to the drawing described.
