Die Erfindung betrifft ein Verfahren zum Herstellen einer Vormontagegruppe für ein Fahrzeug.The invention relates to a method for producing a preassembly group for a vehicle.

Aufgabe der Erfindung ist es, ein Verfahren zum Herstellen einer Vormontagebaugruppe für ein Fahrzeug, die aus zumindest einem metallischen Bauteil und zumindest einem Befestigungselement besteht, zu schaffen, wobei beim Herstellen der Vormontagebaugruppe Toleranzen des metallischen Bauteils ausgeglichen werden können.The object of the invention is to provide a method for producing a preassembly assembly for a vehicle, which consists of at least one metallic component and at least one fastening element, wherein tolerances of the metallic component can be compensated during the manufacture of the preassembly assembly.
Diese Aufgabe wird mit dem Verfahren zum Herstellen einer Vormontagebaugruppe für ein Fahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the method for producing a preassembly assembly for a vehicle having the features of
Erfindungsgemäß wird zum Herstellen einer Vormontagebaugruppe für ein Fahrzeug, bestehend aus einem metallischen und zumindest einem nichtmetallischen Befestigungselement, zunächst das nicht-metallische Befestigungselement in zumindest einer Aufnahme des metallischen Bauteils befestigt, sodass es vorpositioniert ist, aber in zumindest einer Richtung noch um wenige Millimeter verschiebbar ist. Dann wird das metallische Bauteil an zumindest einem Referenzpunkt aufgenommen, das zumindest eine nicht-metallische Befestigungselement in Sollposition auf dem metallischen Bauteil positioniert und anschließend an dem metallischen Bauteil angeschweißt. Ein metallisches Bauteil kann auch eine Baugruppe aus mehreren einzelnen metallischen Bauteilen sein. Das Befestigungselement dient beispielsweise zur Anbringung einer weiteren Baugruppe oder zur zusätzlichen Befestigung des metallischen Bauteils. Für die Erfindung ist es dabei nicht maßgeblich, dass das ganze Befestigungselement aus einem nichtmetallischen Werkstoff besteht, sondern dass das Befestigungselement zumindest im Kontaktbereich zum metallischen Bauteil aus einem nicht-metallischen Werkstoff ist. Es besteht bevorzugt aus einem Kunststoff. Kunststoffe können bevorzugt mit einem Ultraschall-Schweißverfahren gut verschweißt werden. Die Vorteile des Verfahrens sind um so größer, je wichtiger es ist, die vorhandenen Toleranzen zu kompensieren. Dies wird normalerweise bei besonders großen metallischen Bauteilen der Fall sein, oder bei Vormontagebaugruppen, die nur besonders geringe Toleranzen aufweisen dürfen.According to the invention, for producing a preassembled assembly for a vehicle, consisting of a metallic and at least one non-metallic fastening element, first the non-metallic fastening element is fastened in at least one receptacle of the metallic component, so that it is prepositioned, but still displaceable in at least one direction by a few millimeters is. Then, the metallic component is received at at least one reference point, which positions at least one non-metallic fastening element in the desired position on the metallic component and then welded to the metallic component. A metallic component may also be an assembly of several individual metallic components. The fastening element serves, for example, for attaching a further assembly or for additional fastening of the metallic component. For the invention, it is not relevant that the entire fastener consists of a non-metallic material, but that the fastener is at least in the contact region to the metallic component of a non-metallic material. It is preferably made of a plastic. Plastics can preferably be well welded using an ultrasonic welding process. The advantages of the method are the greater, the more important it is to compensate for the existing tolerances. This will normally be the case with very large metallic components, or with pre-assembly assemblies that are only allowed to have very small tolerances.
Es ist allgemein bekannt, ein metallisches Bauteil an seinen Referenzpunkten aufzunehmen, ein zweites metallisches Bauteil in eine Sollposition zum ersten metallischen Bauteil zu bringen und dann die beiden metallischen Bauteile miteinander zu verschweißen. Zum Befestigen eines nicht-metallischen Elements an einem metallischen Bauteil dagegen kommen normalerweise lösbare Verbindungen, wie beispielsweise Schraub- oder Nietverbindungen, zum Einsatz. Dazu muss das metallische Bauteil an den entsprechenden Stellen zur Befestigung des nichtmetallischen Elements Gewinde oder Bohrungen aufweisen. Dies erfordert einerseits einen zusätzlichen Arbeitsschritt zum Herstellen der Gewinde oder Bohrungen, andererseits entstehen dabei wieder Toleranzen. Mit dem erfindungsgemäßen Verfahren kann auf einfache Weise ein nicht-metallisches Befestigungselement an einem metallischen Bauteil angeschweißt werden. Dabei kann das Befestigungselement genau in seiner Sollposition in Bezug auf die Referenzpunkte des metallischen Bauteils angebracht werden, sodass mögliche Toleranzen des metallischen Bauteils in der Anschweißebene ausgeglichen werden können. Zudem wird für die Verbindung des metallischen Bauteils mit dem Befestigungselement außerordentlich wenig Bauraum benötigt.It is generally known to receive a metallic component at its reference points, to bring a second metallic component into a desired position to the first metallic component and then to weld the two metallic components together. For fastening a non-metallic element to a metallic component, on the other hand, normally detachable connections, such as screw or rivet connections, are used. For this purpose, the metallic component must have threads or holes at the appropriate locations for attachment of the non-metallic element. On the one hand, this requires an additional work step for producing the threads or bores, on the other hand tolerances arise again. With the method according to the invention can be welded to a metallic component in a simple manner, a non-metallic fastener. In this case, the fastening element can be mounted exactly in its desired position with respect to the reference points of the metallic component, so that possible tolerances of the metallic component can be compensated in the Anschweißßebene. In addition, extremely little space is required for the connection of the metallic component with the fastener.
Bevorzugt dringt beim Anschweißen der Kunststoff des Befestigungselements zumindest teilweise durch zumindest eine Öffnung im metallischen Bauteil hindurch und umschließt die Öffnung formschlüssig. Die so entstandene formschlüssige Verbindung zwischen dem metallischen Bauteil und dem Befestigungselement ist besonders sicher und belastbar.During welding, the plastic of the fastening element preferably at least partially penetrates through at least one opening in the metallic component and encloses the opening in a form-fitting manner. The resulting positive connection between the metallic component and the fastening element is particularly safe and resilient.
Das Befestigungselement hat idealerweise zugleich die Funktion eines Toleranzausgleichselements, das nach dem in der
Das metallische Bauteil ist günstigerweise ein Tragrohr für eine Instrumententafel, dessen beiden Enden als Referenzpunkte dienen. Derartige Tragrohre erstrecken sich zwischen der linken und der rechten A-Säule einer Fahrzeugkarosserie und dienen zur Versteifung der Karosserie und zur Aufnahme des gesamten Armaturenbretts. Üblicherweise haben solche Tragrohre im mittleren Bereich eine Abstützung, die sich vom Tragrohr zur Bodenbaugruppe im Bereich des Mitteltunnels des Fahrzeugs erstreckt. Das Tragrohr wird mit der Abstützung als Vormontagegruppe außerhalb des Fahrzeugs vorgefertigt. Aufgrund der Größe der Vormontagegruppe weist das Ende der Abstützung, das später mit der Bodenbaugruppe verbunden wird, einige Toleranzen auf. Idealerweise wird an diesem Ende der Abstützung nun ein Befestigungselement angeschweißt. Durch das Anschweißen des Befestigungselements können Toleranzen in den beiden Richtungen der Schweißebene ausgeglichen werden. Wenn das Befestigungselement zudem die Funktion eines Toleranzausgleichselements hat, können beim Anschrauben der Vormontagebaugruppe an die Bodenbaugruppe sogar Toleranzen senkrecht zur Anschweißebene ausgeglichen werden. Dadurch entstehen beim Verschrauben der Vormontagebaugruppe mit der Bodenbaugruppe keinerlei Probleme aufgrund von Toleranzen des Endes der Abstützung, da diese beim Anschweißen des Befestigungselements und ggfs. durch die Funktion des Befestigungselements als Toleranzausgleichselements ausgeglichen werden.The metallic component is conveniently a support tube for an instrument panel, whose two ends serve as reference points. Such support tubes extend between the left and right A pillar of a vehicle body and serve to stiffen the body and to accommodate the entire instrument panel. Typically, such support tubes in the central region have a support which extends from the support tube to the bottom assembly in the region of the center tunnel of the vehicle. The support tube is prefabricated with the support as Vormontagegruppe outside the vehicle. Due to the size of the pre-assembly, the end of the support, which will later be connected to the floor assembly, has some tolerances. Ideally, a fastener is now welded to this end of the support. By welding the fastener tolerances in the two directions of the welding plane can be compensated. In addition, if the fastener has the function of a tolerance compensation element, even tolerances perpendicular to the welding plane can be compensated when screwing the preassembly assembly to the base assembly. As a result, no problems arise due to tolerances of the end of the support when screwing the pre-assembly with the bottom assembly, as these are compensated when welding the fastener and, if necessary. By the function of the fastener as a tolerance compensation element.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, anhand dessen die Erfindung im folgenden näher beschrieben wird. Die einzelnen Figuren zeigen in schematischer Darstellungsweise:In the drawing, an embodiment of the invention is shown, by which the invention will be described in more detail below. The individual figures show in a schematic representation:
Personenkraftfahrzeuge weisen üblicherweise ein Tragrohr auf, das sich zwischen der linken und der rechten A-Säule der Fahrzeugkarosserie erstreckt. Das Tragrohr dient vor allem zur Versteifung der Karosserie und zur Aufnahme des Armaturenbretts. Im mittleren Bereich des Tragrohres ist zusätzlich eine Abstützung angebracht, die das Tragrohr gegenüber der Bodenbaugruppe im Bereich des Mitteltunnels abstützt, um ein Ausknicken des Tragrohres bei axialen Belastungen zu verhindern. die Abstützung ist ein einfaches tiefgezogenes metallisches Blechbauteil. Das Tragrohr bildet zusammen mit dieser Abstützung eine Vormontageeinheit. Die Referenzpunkte dieser Vormontageeinheit werden durch die beiden Enden des Tragrohres gebildet.Passenger cars usually have a support tube extending between the left and right A pillars of the vehicle body. The support tube is used primarily for stiffening the body and for receiving the dashboard. In the middle region of the support tube, a support is additionally attached, which supports the support tube relative to the base assembly in the region of the center tunnel in order to prevent buckling of the support tube under axial loads. The support is a simple deep-drawn metallic sheet metal component. The support tube forms together with this support a pre-assembly. The reference points of this pre-assembly are formed by the two ends of the support tube.
