Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren zum Verbinden zweier Bauteile zu schaffen, welches insbesondere im Karosseriebau eine einfache, sichere und für die Serienfertigung geeignete Verbindung darstellt. Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil von Anspruch 1 genannten Merkmale gelöst.It is an object of the present invention to provide a method to connect two components, which especially in the body shop a simple, safe and represents a suitable connection for mass production. According to the invention, this object is achieved by the characterizing Part of claim 1 mentioned features solved.

Durch den zuletzt erstarrenden Kernbereich zieht sich das Verbindungsteil in dem Bereich um die Hinterschneidung des ersten Bauteiles beim Erstarren so zusammen, daß sich eine Spannwirkung mit sehr hohen Kräften ergibt, welche bei vollständig erstarrtem Verbindungsteil zu einer äußerst stabilen Verbindung zwischen dem ersten Bauteil und dem Verbindungsteil führt.Through the last solidifying core area is drawing the connecting part in the area around the undercut of the first component when solidifying together, that a clamping effect with very high Forces results, which in completely solidified connection part to a very stable connection between the first component and the connecting part leads.

Anschließend wird erfindungsgemäß das zweite Bauteil an dem Verbindungsteil angebracht, wodurch letztendlich die beiden Bauteile in einfacher Weise miteinander verbunden werden.

Die Figuren 1 und 2 zeigen jeweils ein als Längsträger 1 ausgebildetes erstes Bauteil einer in ihrer Gesamtheit nicht dargestellten Fahrzeugkarosserie. Der Längsträger 1 verläuft in Längsrichtung der Fahrzeugkarosserie, z.B. an einer Dachseite, und weist an einer Seitenfläche eine Hinterschneidung 2 auf, die in diesem Fall als an sich bekannte Schwalbenschwanz-Führung ausgebildet ist. Dabei sind auch andere Ausbildungen der Hinterschneidung 2 möglich, z.B. als T-Nut. Die Hinterschneidung 2 kann nur in einem Teilbereich der Länge des Längsträgers 1 vorgesehen sein, verläuft aber aus fertigungstechnischen Gründen meist über seine gesamte Länge.Figures 1 and 2 each show a longitudinal beam 1 trained first component one in its entirety not shown vehicle body. Of the Side member 1 extends in the longitudinal direction of the vehicle body, e.g. on a roof side, and points to one Side surface of an undercut 2 on, in this case as a known dovetail guide is trained. There are also other training the undercut 2 possible, e.g. as a T-slot. The undercut 2 can only in a partial area be provided the length of the longitudinal member 1, but usually runs for manufacturing reasons over its entire length.

Im Bereich der Hinterschneidung 2 wird über einen Teil der Länge des Längsträgers 1 eine nicht dargestellte Gießform angesetzt, in welche dann flüssiges Metall zur Bildung eines Verbindungsteils 3 eingegossen wird. Die Gießform kann dabei je nach dem zum Einsatz kommenden Gießverfahren in an sich bekannter Weise als Sand-, Kokillen- oder Druckgießform ausgebildet sein.In the area of the undercut 2 is about a part the length of the longitudinal member 1 is not shown Mold applied, in which then liquid metal is poured to form a connecting part 3. The mold can be used depending on the used Casting in a conventional manner as Sand, mold or die to be formed.

Das Verbindungsteil 3 und die Hinterschneidung 2 sind dabei so ausgelegt bzw. aufeinander abgestimmt, daß bei der Erstarrung ein zuletzt erstarrender Kernbereich 4 des Verbindungsteils 3 den in der Hinterschneidung 2 sich befindlichen Anteil des Verbindungsteils 3 zusammenzieht, so daß sich durch die daraus entstehenden Spannungen das Verbindungsteil 3 mit dem Bauteil 1 fest verbindet.The connecting part 3 and the undercut 2 are thereby designed or matched to each other that during solidification a last solidifying core area 4 of the connecting part 3 in the undercut 2 located portion of the connecting part 3 contracts, so that by the resulting voltages the connecting part 3 with the Part 1 firmly connects.

Mit anderen Worten, die durch das Zusammenziehen des zuletzt erstarrenden Kernbereichs 4 entstehenden Kräfte verlaufen genau so, daß eine sehr große Spannwirkung zwischen dem Verbindungsteil 3 und dem Längsträger 1 zustande kommt. Die entsprechende Auslegung der Hinterschneidung 2 und des Verbindungsteils 3 können z.B. durch Versuche oder Computersimulation ermittelt werden.In other words, by contracting the last solidifying core region 4 resulting forces Exactly the same, that a very large clamping effect between the connecting part 3 and the longitudinal member 1 comes about. The appropriate interpretation of Undercut 2 and the connecting part 3 can e.g. determined by experiments or computer simulation become.

An das Verbindungsteil 3 wird anschließend in einem dem Bauteil 1 abgewandten Bereich 5 des Verbindungsteils 3 ein zweites Bauteil 6, in diesem Fall ein Querträger 6 der Fahrzeugkarosserie angebracht. Dies kann durch bewährte Verbindungsverfahren, wie z.B. Schrauben oder Schweißen erfolgen. Beim Anschweißen des Querträgers 6 an das Verbindungsteil 3 sind weitaus weniger und auch kleinere Schweißnähte erforderlich, als bei einer direkten Anschweißung des Querträgers 6 an den Längsträger 1, wie dies beim Stand der Technik der Fall ist. Dadurch ergeben sich weitaus weniger Verspannungen und ein sehr viel geringerer Verzug in den beiden Bauteilen 1 und 6.At the connecting part 3 is then in a the part 1 facing away from area 5 of the connecting part 3 a second component 6, in this case a Cross member 6 of the vehicle body attached. This can be replaced by well-established joining methods, e.g. Screwing or welding done. When welding of the cross member 6 to the connecting part 3 are far out less and smaller welds required, as in a direct welding of the cross member 6 to the longitudinal member 1, as in the state of Technique is the case. This results in a lot less tension and a lot less Warpage in the two components 1 and 6.

Das Bauteil 6 stößt in den abgebildeten Fällen an das Bauteil 1 T-förmig an. Es können durch das Verbindungsteil 3 je nach Bedarf auch Bauteile mit beliebigen anderen Winkeln zueinander verbunden werden, wobei das Verbindungsteil 3 auch gebogen sein kann. Das zweite Bauteil 6 kann dabei zylinderförmig, rechteckig oder von beliebigem anderen Querschnitt sein. Selbstverständlich wird dann der Bereich 5 des Verbindungsteils 3 an den entsprechenden Querschnitt des zweiten Bauteils 6 angepaßt.The component 6 abuts in the cases shown on the Component 1 T-shaped. It can through the connecting part 3 as required also components with any other angles are connected to each other, where the connecting part 3 can also be bent. The second component 6 can be cylindrical, rectangular or of any other cross-section. Of course then becomes the area 5 of the connecting part 3 to the corresponding cross section of the second Part 6 adapted.

Im Gegensatz zu der in Fig. 1 dargestellten sogenannten negativen Hinterschneidung 2 ist gemäß Fig. 2 ein Längsträger 1 mit einer sogenannten positiven Hinterschneidung 2 dargestellt. Das Verbindungsteil 3 paßt sich in beiden Fällen beim Gießen an die entsprechende Hinterschneidung 2 an und es ergibt sich wie bereits oben dargelegt durch den zuletzt erstarrenden Kernbereich 4 eine feste Verbindung zwischen dem Bauteil 1 und dem Verbindungsteil 3.In contrast to the so-called negative undercut 2 is shown in FIG. 2 a Side member 1 with a so-called positive undercut 2 shown. The connecting part 3 fits in both cases when pouring to the corresponding Undercut 2 and it results as already set forth above by the last solidifying core area 4 is a firm connection between the component 1 and the connecting part 3.

In nicht dargestellter Art und Weise können gemäß beiden beschriebenen Ausführungsformen auch mehrere Gießformen an einen Querträger 1 angebracht werden, wodurch mehrere gleichartige Verbindungsteile 3 hergestellt und mehrere Querträger 6 an einen Längsträger 1 angebracht werden können.In a manner not shown, according to both described embodiments also several molds be attached to a cross member 1, whereby made several similar connection parts 3 and a plurality of cross member 6 to a side member. 1 can be attached.

Alternativ wäre auch eine Gießform denkbar, mit welcher zwei oder mehrere Verbindungsteile 3 mit einem einzigen Abguß an einen Längsträger 1 angegossen werden können. Auch so könnten dann mehrere Querträger 6 an einen Längsträger 1 angebracht werden.Alternatively, a mold would be conceivable with which two or more connecting parts 3 with a single casting to be cast on a side rail 1 can. Even so, then a plurality of cross member. 6 attached to a side rail 1.

Das beschriebene Verfahren ist bei allen bekannten Gießverfahren und Legierungen bzw. Materialien durchführbar. Die Art der Anbringung des Querträgers 6 an dem Verbindungsteil 3 kann dabei je nach Material variieren.The method described is in all known Casting and alloys or materials feasible. The type of attachment of the cross member 6 The connecting part 3 can vary depending on the material.

In jedem Fall ist beim Gießen bzw. beim Herstellen der Gießform zu beachten, daß auch bei gebogenem Verbindungsteil 3 die Gießform nach dem Gießen wieder getrennt werden kann.In any case, when casting or when making the Mold to be noted that even with bent connecting part 3, the mold after pouring separated again can be.
