Abstract
Description
Die Erfindung betrifft eine Bodenstruktur eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a floor structure of a motor vehicle according to the preamble of claim 1
Aus dem Serienfahrzeugbau sind Bodenstrukturen von Kraftfahrzeugen bekannt, deren Unterbodenverkleidung so ausgebildet ist, dass ein aerodynamisch günstiges Verhalten erzielt wird.Out the serial vehicle construction are known floor structures of motor vehicles, whose undershield is designed so that an aerodynamic favorable Behavior is achieved.

Um die Resonatorenelemente zu bilden, ist es notwendig, die Unterbodenverkleidung doppelwandig auszugestalten, so dass ein aufwendiger Herstellungsprozess erforderlich ist.Around To form the resonator elements, it is necessary to the underbody paneling double-walled design, so that a complex manufacturing process is required.
Es besteht daher die Aufgabe, eine Bodenstruktur für ein Kraftfahrzeug unter Beibehaltung der schallabsorbierenden Eigenschaften zu schaffen, die kostengünstig herstellbar ist.It There is therefore the task of maintaining a floor structure for a motor vehicle To create the sound-absorbing properties that can be produced inexpensively is.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The Task is according to the invention with the features of claim 1.
Dadurch, dass in dem Hohlraum eine Zwischenschicht vorgesehen ist, die geräuschabsorbierend wirkt, ist es nicht mehr notwendig, die Unterbodenverkleidung doppelwandig auszubilden. Je nach Ausbildung der Zwischenschicht kann damit in einfacher Weise die schallabsorbierende Eigenschaft der Bodenstruktur beeinflusst werden. Zudem können durch die Zwischenschicht andere akustisch wirksame Bauteile, wie beispielsweise im Fahrzeuginnenraum angeordnete Bodenbeläge, dünner ausgebildet werden, so dass der Fahrzeuginnenraum vergrößert werden kann. Von zusätzlichem Vorteil ist, dass die Zwischenschicht auch Klappergeräusche zwischen Bodenplatte und Unterbodenverkleidung reduziert.Thereby, that in the cavity an intermediate layer is provided, the sound absorbing it is no longer necessary, the underbody paneling double-walled train. Depending on the design of the intermediate layer can thus in simply the sound absorbing property of the soil structure to be influenced. In addition, through the intermediate layer other acoustically effective components, such as arranged in the vehicle interior floor coverings are thinner, so that the vehicle interior be enlarged can. From additional The advantage is that the intermediate layer also rattles between floor plate and underbody paneling reduced.
In einer bevorzugten Ausführungsform ist die Zwischenschicht hochfrequenzabsorbierend ausgebildet, so dass Abroll- und Windgeräusche im Innenraum verringert werden können.In a preferred embodiment the intermediate layer is designed to absorb high frequency, then that rolling and wind noise can be reduced in the interior.
Als hochfrequenzabsorbierende Zwischenschicht kann eine Luftpolsterfolie eingesetzt werden, die je nach Größe der Luftpolster entsprechende Frequenzen absorbiert.When High frequency absorbing intermediate layer may be a bubble wrap be used depending on the size of the air cushion corresponding Absorbs frequencies.
Denkbar ist auch, dass als Zwischenschicht ein Polyestervlies vorgesehen ist, das in entsprechend zugeschnittener Größe in die Hohlräume eingesetzt werden kann.Conceivable is also that provided as an intermediate layer, a polyester fleece is that used in appropriately tailored size in the cavities can be.
Wird das Polyestervlies zusätzlich mit einer Folienummantelung versehen, können zusätzliche Hohlräume gebildet werden, die als Luftschalldämmschicht wirken.Becomes the polyester fleece in addition provided with a foil coating, additional cavities can be formed be that as an airborne sound insulation layer Act.
Anhand der Zeichnung wird im Folgenden die Erfindung näher erläutert. Dabei zeigen:Based The drawing will be explained in more detail below the invention. Showing:
