Abstract
Mitteltunnel für die Bodengruppe eines Kraftfahrzeuges, der sich von einer Stirnwand bis zu einem hinteren Querträger erstreckt, wobei der Mitteltunnel durch eine obere und eine untere Blechschale gebildet ist, wobei die beiden Blechschalen eine U-Grundform aufweisen und wobei im Mitteltunnel Längshohlprofile mit Hohlräumen vorgesehen sind, dadurch gekennzeichnet, dass die obere und untere Blechschale (4, 5) zusätzlich in radialer Richtung zur Längsachse des Mitteltunnels (2) Abstufungen oder dergleichen in einer solchen Form aufweisen, dass im befestigten Zustand der Blechschalen (4, 5) durch die Anlagestellen (9, 10, 11) der Blechschalen (4, 5) aneinander Längshohlprofile mit Hohlräumen (6, 7, 8) gebildet sind und dass ein nach unten hin offenes Ende (15) des Mitteltunnels (2) durch mindestens einen Querträger (14) geschlossen ist.Center tunnel for the floor assembly of a motor vehicle, which extends from an end wall to a rear cross member, the center tunnel being formed by an upper and a lower sheet metal shell, the two sheet metal shells having a U-shaped base and with longitudinal hollow profiles with cavities being provided in the center tunnel , characterized in that the upper and lower sheet metal shells (4, 5) additionally have gradations or the like in the radial direction to the longitudinal axis of the central tunnel (2) in such a form that in the fastened state of the sheet metal shells (4, 5) through the contact points ( 9, 10, 11) of the sheet metal shells (4, 5) longitudinal hollow profiles with cavities (6, 7, 8) are formed and that an end (15) of the center tunnel (2) which is open towards the bottom is closed by at least one cross member (14) is.
Description
Die Erfindung betrifft einen Mitteltunnel für die Bodengruppe eines Kraftfahrzeuges gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a central tunnel for the Floor assembly of a motor vehicle according to the preamble of the claim 1.

Aufgabe der Erfindung ist es, einen Mitteltunnel für die Bodengruppe eines Kraftfahrzeuges zu schaffen, bei dem der Mitteltunnel sowohl in Fahrzeuglängsrichtung als auch in Fahrzeugquerrichtung eine hohe Steifigkeit aufweist und gleichzeitig leicht baut.The object of the invention is a Center tunnel for to create the floor pan of a motor vehicle in which the center tunnel both in the vehicle's longitudinal direction and also has a high degree of rigidity in the transverse direction of the vehicle and at the same time builds easily.
Diese Aufgabe wird bei einem gattungsgemäßen Mitteltunnel durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is carried out in a generic central tunnel solved by the characterizing features of claim 1.
Durch die doppelschalige Ausbildung des Mitteltunnels in der Weise, dass zwischen den beiden Schalen Längshohlprofile gebildet sind und durch das Verschließen des Mitteltunnels an seiner Unterseite mit Querträgern ergibt sich ein sehr steifes Bauteil, das mit dem bei Sportwagen eingesetzten Zentralrohr vergleichbar ist.Due to the double-shell training of the middle tunnel in such a way that between the two shells Longitudinal hollow profiles are formed and by closing the center tunnel on it Bottom with cross beams the result is a very stiff component that matches that of a sports car used central tube is comparable.
Durch die Reduzierung der Bauteile auf zwei aneinander angepaßte Schalen oder Bleche, sind bei der Herstellung entsprechend nur zwei Werkzeugsätze nötig.By reducing the number of components on two matched Shells or sheets are only two in production Toolkits necessary.
Von Vorteil ist ferner, daß an dem Mitteltunnel die Aufnahmen für die Querträger, die zu den Seitenschwellern führen, integriert sind.Another advantage is that on the Middle tunnel the recordings for the cross beams, that lead to the side skirts, are integrated.
Durch die Ausbildung des Mitteltunnels als ein separates Bauteil der Bodengruppe, an das seitlich die zu den Seitenschwellern führenden Bodenbleche angeordnet sind, ist es möglich, kleinere Werkzeuge zur Herstellung des Mitteltunnels zu verwenden. Ferner sind durch die kompaktere Bauweise des Mitteltunnels kleinere Radien in der Form der beiden den Mitteltunnel bildenden Flächen möglich.Through the formation of the middle tunnel as a separate component of the floor assembly to which the side leading the side skirts Floor panels are arranged, it is possible to use smaller tools Manufacture to use the middle tunnel. Furthermore, through the compact design of the center tunnel, smaller radii in shape of the two surfaces forming the central tunnel.
Eine Ausführungsform der Erfindung wird nachstehend anhand einer einzigen Figur beschrieben, die eine perspektivische Querschnittsansicht auf den das Getriebegehäuse aufnehmenden Abschnitt des Mitteltunnels zeigt.An embodiment of the invention is as follows described with a single figure, the perspective Cross-sectional view of the portion receiving the gear housing of the middle tunnel shows.
