Description

Die Erfindung betrifft ein Verfahren zum Verbinden von wenigstens zwei Bauteilen, insbesondere Karosseriebauteilen von Kraftfahrzeugen, nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to a method for connecting at least two components, in particular body components of motor vehicles, according to the in the preamble Art defined by claim 1.

Beim Karosseriebau von Kraftfahrzeugen werden gemäß einem aus der Praxis bekannten Stand der Technik zwei Bauteile, insbesondere T-förmig aneinanderstoßende Längs- und Querträger, durch Schweißen miteinander verbunden. Diese sehr gebräuchlichen Schweißverbindungen haben jedoch den Nachteil, daß dafür sehr große Schweißnähte notwendig sind und die beiden miteinander zu verbindenden Teile sich durch Wärmeeinwirkung extrem verziehen können, wodurch die Maßgenauigkeit der gesamten Karosseriestruktur, die durch das Verbinden mehrerer Bauteile miteinander entsteht, nicht auf ein hohes Niveau gebracht werden kann. In the body construction of motor vehicles according to a prior art known from practice two Components, in particular T-shaped abutting Longitudinal and cross members, by welding together connected. These very common welded joints However, they have the disadvantage that they are very large Welds are necessary and the two together Parts to be connected become extremely exposed to heat can warp, causing the dimensional accuracy of the entire body structure by connecting of several components with each other, not on one high level can be brought.

Aus der DE-OS 1 811 010 ist ein Verfahren zum gegenseitigen Verbinden von zwei Metallteilen bekannt, bei welchem die Metallteile an ihren Stoßflächen mit einander gegenüberliegenden, sich nach innen erweiternden Ausnehmungen versehen sind. Diese Ausnehmungen bilden bei zusammengefügten Metallteilen einen zusammenhängenden Hohlraum. Zur Verbindung der beiden Teile wird in diesen Hohlraum erwärmtes Metall eingebracht, das beim Erkalten schrumpft und somit die Metallteile zusammenzieht.DE-OS 1 811 010 describes a mutual method Connecting two metal parts known at which the metal parts on their abutting surfaces with each other opposite, expanding inwards Recesses are provided. Form these recesses in the case of joined metal parts, a coherent Cavity. To connect the two parts heated metal is introduced into this cavity, the shrinks on cooling and thus contracts the metal parts.

Das dort beschriebene Verfahren mag bei einfachen Bauteilen durchaus für eine Verbindung geeignet sein, im Karosseriebau kann es jedoch aufgrund der dort auftretenden komplizierten Strukturen nicht in geeigneter Weise eingesetzt werden.The method described there may be for simple components be quite suitable for a connection in Body construction can, however, because of the occurring there complicated structures not appropriate Way are used.

Die US-PS 982,265 beschreibt ein Verfahren zum Anbinden einer Stange an ein Rohr, wobei in das Rohr Metall eingegossen wird und somit die Stange mit dem Rohr verbunden wird.US Pat. No. 982,265 describes a method for binding a rod to a pipe, with metal in the pipe is poured and thus the rod with the tube is connected.

Des weiteren ist aus der US-PS 1,021,437 eine Verbindung für zwei Rohre bekannt, die durch das Eingießen von flüssigem Metall in den Verbindungsbereich der beiden T-förmig aneinanderstoßenden Rohre zustande kommt.Furthermore, there is a connection from US Pat. No. 1,021,437 known for two pipes by pouring of liquid metal in the connection area of the two T-shaped abutting tubes is coming.

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. The object of the present invention is a method to connect two components to create which a simple, safe one, particularly in body construction and represents a suitable connection for series production.

Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil von Anspruch 1 genannten Merkmale gelöst.According to the invention, this task is characterized by Features mentioned in claim 1 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.The core, which has recently solidified, runs through the connecting part in the area around the undercut of the first component when it solidifies, that there is a tension with very high Forces results when the connecting part is completely solidified to an extremely 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. Je nach der gewählten Form des Verbindungsteiles entsteht somit eine Anbindung des zweiten Bauteils an das erste Bauteil in beliebiger Art und Weise.Then the second component according to the invention attached to the connecting part, which ultimately the two components together in a simple manner get connected. Depending on the selected form of the Connection part thus creates a connection of the second component to the first component in any Way.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und aus dem nachfolgend anhand der Zeichnung prinzipmäßig dargestellten Ausführungsbeispiel.Advantageous refinements and developments of Invention result from the dependent claims and from the principle shown below with reference to the drawing Embodiment.

Es zeigt:

zwei durch eine zweite Ausführungsform des erfindungsgemäßen Verfahrens verbundene Bauteile.
It shows:
Fig. 1
Two components connected by a first embodiment of the method according to the invention; and
Fig. 2
two components connected by a second embodiment of the method according to the invention.

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 SchwalbenschwanzFührung 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 one as a longitudinal beam 1 formed first component in its entirety not shown vehicle body. Of the Side member 1 runs in the longitudinal direction of the vehicle body, e.g. on a roof side, and points on one Side surface an undercut 2, which in in this case as a known dovetail guide is trained. There are also other training courses undercut 2 possible, e.g. as a T-slot. The undercut 2 can only be in a partial area the length of the longitudinal beam 1 may be provided, runs mostly 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 over a part the length of the longitudinal beam 1 a not shown Cast mold, in which then liquid metal is cast to form a connecting part 3. The mold can vary depending on the one used Casting process in a manner known per se as Sand, mold or die casting mold.

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 designed or coordinated so that in the case of solidification, a core area that solidifies last 4 of the connecting part 3 in the undercut 2 located part of the connecting part 3 contracts, so that by the result arising voltages the connecting part 3 with the Component 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 area 4 arising forces run exactly so that a very great tension between the connecting part 3 and the side member 1 comes about. The corresponding interpretation of the 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 one Area 5 of the connecting part facing away from component 1 3 a second component 6, in this case a Cross member 6 of the vehicle body attached. This can be established using proven connection methods, e.g. Screwing or welding is done. When welding of the cross member 6 to the connecting part 3 are far fewer and smaller weld seams required, than with a direct welding of the cross member 6 on the longitudinal beam 1, as is the case with the Technology is the case. This results in a lot less tension and a lot less Delay in both 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 Component 1 T-shaped. It can through the connecting part 3 Depending on requirements also components with any other angles are connected to each other, whereby 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 the area 5 of the connecting part 3 to the corresponding cross section of the second Component 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 shown in Fig. 1 negative undercut 2 is a according to FIG. 2 Side member 1 with a so-called positive undercut 2 shown. The connecting part 3 fits in both cases when casting to the corresponding one Undercut 2 and it results as already set out above by the last solidifying core area 4 a firm connection between 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 several similar connecting parts 3 are produced and a plurality of cross members 6 on a longitudinal 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 casting mold with which it is also conceivable two or more connecting parts 3 with one single cast can be cast onto a side member 1 can. Several cross members 6 could then also be used in this way be attached to a side member 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 known for all Casting process 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 manufacturing Casting mold to note that even with a bent connecting part 3 the casting mold is separated again after casting can be.
