Abstract
In einem Blechumformteil, welches eine Getriebeaufnahme für ein Getriebe darstellt, werden zur Verbesserung der lokalen dynamischen Steifigkeit dieser rohbauseitigen Getriebeanbindung Schweißmuttern verwendet, die formschlüssig in die Rohbaustruktur integriert werden. Hierzu werden die Schweißmuttern von einem Quellschaumeinleger umgeben, der im Lackprozess unter Temperatureinfluss expandiert, um die Schweißmuttern mit den angrenzenden Rohbauteilen voll umfänglich zu verbinden.In a sheet-metal forming part, which constitutes a gearbox mount for a gearbox, welding nuts are used to improve the local dynamic rigidity of this shell-side gearbox connection, which are integrally integrated into the bodyshell structure. For this purpose, the weld nuts are surrounded by a foam insert, which expands in the paint process under the influence of temperature to fully connect the weld nuts with the adjacent shell components.
Description
Die Erfindung bezieht sich auf eine Verbindungsvorrichtung und ein Verfahren zur Herstellung dieser Verbindungsvorrichtung nach den Ansprüchen 1 und 4. The invention relates to a connecting device and a method for producing this connecting device according to
Aus der
Aufgabe der Erfindung ist es, eine lokale dynamische Steifigkeit bzw. Eingangs-Steifigkeit einer rohbauseitigen Getriebeanbindung an einem Getriebeträger eines Karosseriebaus in x-, y- und z-Richtung zu verbessern. The object of the invention is to improve a local dynamic stiffness or input rigidity of a shell-side gear connection to a gear carrier of a body in the x-, y- and z-direction.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 4 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche. This object is achieved by the features of
Durch die Erfindung wird die lokale dynamische Steifigkeit der rohbauseitigen Getriebeanbindungen in allen Belastungsrichtungen verbessert, indem Schweißmuttern des Getriebeträgers jeweils von einem expandierenden Quellschaum-einleger rundherum umgeben sind, mit der die Schweißmuttern mit dem angrenzenden Rohbauteilen der Karosserie voll umfänglich verbunden werden. Es ist bei dieser Ausführung nach der Erfindung vorgesehen, dass die Schweißmuttern vorzugsweise nebeneinander in Reihe im Blechformteil angeordnet sind und der Quellschaumeinleger sich in der Länge und Breite um die Scheißmuttern herum erstreckt. Durch den in allen Richtungen im Rohbauteil bzw. im Blechumformteil des Karosserierohbaus, angeordneten Quellschaumeinleger sind die Schweißmuttern von allen Seiten her formschlüssig in die Rohbaustruktur eingebunden, so dass Belastungen in den x-, y-, z-Richtungen nach allen Seiten abgestützt aufgenommen werden können. Nach einer weiteren Ausführung der Erfindung ist vorgesehen, dass die Verbindungsvorrichtung wenigstens drei Schweißmuttern umfasst, wobei die endseitigen Schweißmuttern von einem gehäuseartigen Einleger umgeben sind. Durch diese gehäuseartigen und vom Quellschaumeinleger umgebenden Einleger, wird zusätzlich eine Stabilität der von der Quellschaum-einleger umgebenen Schweißmuttern erzielt. By the invention, the local dynamic stiffness of the rohbauseitigen gear connections is improved in all load directions by welding nuts of the gear carrier are each surrounded by an expanding foam insert around, with the weld nuts are fully connected to the adjacent shell components of the body. It is provided in this embodiment according to the invention that the weld nuts are preferably arranged side by side in series in the sheet metal part and the foam insert extends in the length and width around the shit nuts around. Due to the in all directions in the shell part or sheet metal forming part of the body shell, arranged foam insert the weld nuts are positively integrated from all sides in the shell structure, so that loads in the x, y, z directions can be supported supported on all sides , According to a further embodiment of the invention it is provided that the connecting device comprises at least three welding nuts, wherein the end-side welding nuts are surrounded by a box-like insert. By this case-like and surrounding of the foam applicator deposit, in addition, a stability of the surrounded by the foam insert foam welding nuts is achieved.
Das Expandieren des Quellschaumeinlegers erfolgt in einem Verfahrensschritt, nämlich in einem Lackierungsprozess des Fahrzeugs unter Temperatureinfluss, wobei der Quellschaum-einleger sich zu den angrenzenden Rohbauteilen ausbreitet und sich mit diesem verbindet und eine Festigkeitseinheit bildet und die Scheißmuttern einen Formschluss mit den Rohbauteilen bilden. The Expanding the Quellschaumeinlegers takes place in a process step, namely in a painting process of the vehicle under the influence of temperature, the Quellschaum-depositor propagates to the adjacent Rohbauteilen and connects to this and forms a strength unit and the nuts form a positive engagement with the shell components.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher beschrieben. An embodiment of the invention is illustrated in the drawings and will be described in more detail below.
