Abstract
Description
Die Erfindung betrifft eine Unterbodenverkleidung für ein Kraftfahrzeug nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to an underbody paneling for a motor vehicle after further defined in the preamble of claim 1 Art.
Gattungsgemäße
Unterbodenverkleidungen für Kraftfahrzeuge sind beispielsweise
aus der
Der Nachteil der meisten dieser bekannten Unterbodenverkleidungen ist jedoch deren hohe Materialdicke und das sich dadurch ergebende hohe Gewicht sowie die hohen Kosten dieser Unterbodenverkleidungen, da häufig teure Materialien, wie beispielsweise Glasfaser, eingesetzt werden müssen, um eine ausreichende Steifigkeit sicherzustellen.Of the Disadvantage of most of these known underbody panels is but their high material thickness and the resulting high weight as well as the high cost of these underbody panels, as common expensive materials, such as glass fiber, are used need to ensure sufficient rigidity.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Unterbodenverkleidung für ein Kraftfahrzeug zu schaffen, welche eine hohe Steifigkeit bei geringer Dicke und damit geringer Masse aufweist und mit geringem Aufwand und damit kostengünstig herzustellen ist.It is therefore an object of the present invention, an underbody paneling for a motor vehicle to create, which has a high rigidity has a small thickness and thus low mass and low Effort and therefore inexpensive to manufacture.
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.
Durch den erfindungsgemäßen Einsatz des wenigstens einen Armierungselements zur Versteifung der Unterbodenverkleidung ist eine hohe Steifigkeit der Unterbodenverkleidung auch mit geringer Materialdicke und damit geringer Masse zu erreichen, wobei die Kosten für ein derartiges Armierungselement erheblich niedriger anzusetzen sind als bei aus dem Stand der Technik bekannten Lösungen, da auf teure Materialien verzichtet werden kann. Umgekehrt kann bei gleicher Materialdicke eine erheblich höhere Steifigkeit der Unterbodenverkleidung erreicht werden, um ein Durchhängen der Unterbodenverkleidung zu vermeiden.By the use according to the invention of at least one Armierungselements for stiffening the underbody paneling is a high rigidity of the underbody paneling even with low material thickness and thus to achieve lower mass, the cost of to set such a reinforcing element considerably lower are as in solutions known from the prior art, because expensive materials can be dispensed with. Conversely, can with the same material thickness, a considerably higher rigidity the underbody cladding can be reached to sag to avoid the underbody cladding.
Da das wenigstens eine Armierungselement gezielt dort eingesetzt werden kann, wo hohe Belastungen zu erwarten sind, können aerodynamische Belastungen, bei spielsweise durch Unterdruck entstehende Zugspannungen, durch die Unterbodenverkleidung sehr gut aufgenommen werden. Die erfindungsgemäße Unterbodenverkleidung ist damit vor allem für diejenigen Anwendungsfälle gut geeignet, bei denen wenige Befestigungspunkte zur Anbringung der Unterbodenverkleidung an der Karosserie vorhanden sind.There the at least one reinforcing element are used selectively there can, where high loads are to be expected, aerodynamic loads, in example by negative pressure resulting tensile stresses, by the underbody paneling is very well received. The inventive Underbody covering is thus especially for those Use cases well suited, where few attachment points for attaching the underbody paneling to the bodywork are.
Zusätzliche Verbindungselemente können eingespart werden, wenn in einer vorteilhaften Weiterbildung der Erfindung die Unterbodenverkleidung und das Armierungselement an wenigstens einer gemeinsamen Verbindungsstelle mit der Karosserie verbunden sind. Dadurch kann eine Kostenerhöhung aufgrund des wenigstens einen Armierungselements vermieden werden.additional Connecting elements can be saved if in one advantageous development of the invention, the underbody paneling and the reinforcing element at at least one common connection point connected to the bodywork. This may increase costs due to the at least one reinforcing element can be avoided.
Eine besonders einfache und sichere Anbringung des Armierungselements an der Unterbodenverkleidung ergibt sich, wenn das Armierungselement mittels Nieten mit der Unterbodenverkleidung verbunden ist.A particularly simple and secure attachment of the reinforcing element on the underbody cladding results when the reinforcing element connected by rivets to the underbody paneling.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass das wenigstens eine Armierungselement in Längsrichtung des Kraftfahrzeugs verläuft. Eine solche Anbringung des wenigstens einen Armierungselements entspricht der am häufigsten auftretenden Belastung und stellt somit eine optimale Anordnung für sehr viele Belastungsfälle dar.In a further advantageous embodiment of the invention can be provided be that the at least one reinforcing element in the longitudinal direction of Motor vehicle runs. Such attachment of at least a reinforcing element corresponds to the most common Load and thus provides an optimal arrangement for very many load cases.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den restlichen Unteransprüchen. Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig dargestellt.Further yield advantageous embodiments and refinements of the invention from the remaining subclaims. The following is an embodiment of the invention with reference to the drawing shown in principle.
