Abstract
Description
Die Erfindung betrifft eine Bodenstruktur für ein Kraftfahrzeug, mit zwei Seitenteilen und einem Mitteltunnel nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a floor structure for a motor vehicle, with two side parts and a center tunnel after in the preamble Of claim 1 further defined type.

Problematisch bei den bekannten Bodenstrukturen ist, dass sich im Crashfall der Mitteltunnel erheblich verformt und somit nichts zu Steifigkeit der Karosserie beitragen kann. Dies ist insbesondere dann der Fall, wenn ein Karosserieteil, beispielsweise der Instrumententräger, über ein entsprechendes Bauteil an dem Mitteltunnel abgestützt ist, so dass das Bauteil im Crashfall eine entsprechende Verformungsenergie in den Mitteltunnel einbringt.Problematic in the known soil structures is that in the event of a crash of Central tunnel significantly deformed and thus nothing to stiffness the body can contribute. This is especially the case if a body part, for example, the instrument carrier over a corresponding component supported on the center tunnel is, so that the component in the event of a crash a corresponding deformation energy into the center tunnel.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Bodenstruktur für ein Kraftfahrzeug zu schaffen, welche in der Lage ist, im Crashfall hohe Kräfte aufzunehmen.It is therefore an object of the present invention, a soil structure for a motor vehicle that is capable of to absorb high forces in the event of a crash.
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 das erfindungsgemäße, quer zur Längsrichtung des Kraftfahrzeugs verlaufende Versteifungsteil ergibt sich eine sehr gute Versteifung des gesamten Mitteltunnels, so dass dieser insbesondere im Crashfall sehr hohe Kräfte aufnehmen kann. Auch für den normalen Betrieb des Kraftfahrzeugs ergibt sich durch das erfindungsgemäße Versteifungsteil jedoch eine größere Steifigkeit der Bodenstruktur und somit der gesamten Karosserie.By the inventive, transverse to the longitudinal direction of the motor vehicle extending stiffening results in a very good stiffening of the entire center tunnel, so this one especially in the event of a crash can absorb very high forces. Also results for the normal operation of the motor vehicle through the stiffening part according to the invention but a greater rigidity of the soil structure and thus the entire body.
Das erfindungsgemäße Versteifungsteil erfordert vorteilhafterweise nur einen kleinen Bauraum und lässt sich somit an den verschiedensten Stellen entlang des Mitteltunnels unterbringen, wenn es in einer vorteilhaften Weiterbildung der Erfindung als wenigstens annähernd flaches, zweidimensionales Bauteil ausgebildet ist.The Stiffening part according to the invention advantageously requires only a small space and can thus be used on the most diverse Accommodate places along the center tunnel when it is in one advantageous development of the invention as at least approximately flat, two-dimensional component is formed.
Wenn des weiteren vorgesehen ist, dass an dem Versteifungsteil ein Abstützelement zur wenigstens mittelbaren Verbindung mit einem Karosserieteil abgestützt ist, so wird über das Abstützelement eine bestimmte Verformungsenergie in den Mitteltunnel eingeleitet, welche dieser aufgrund des Versteifungsteils besser aufnehmen kann, so dass letztendlich eine Abstützung des Karosserieteils an dem Mitteltunnel und damit eine Versteifung der Karosserie gegeben ist.If is further provided that on the stiffening part a supporting element supported for at least indirect connection with a body part is, so on the support element is a specific Deformation energy introduced into the center tunnel, which this due to the stiffening part can absorb better, so that ultimately a Support of the body part to the center tunnel and so that a stiffening of the body is given.

Nachfolgend sind Ausführungsbeispiele der Erfindung anhand der Zeichnung prinzipmäßig dargestellt.Further yield advantageous embodiments and refinements of the invention from the remaining subclaims.
