Abstract
Description
Die Erfindung betrifft ein Verfahren zum Montieren eines Dachmoduls an einer Karosserie eines Kraftwagens.The The invention relates to a method for mounting a roof module on a body of a motor vehicle.
Zur Gewichtseinsparung – und damit zur Verringerung von Kraftstoffverbrauch mit CO2-Emissionen – werden im Karosseriebau von Personenkraftwagen zunehmend Kombinationen von Stahl- und Leichtmetallbauteilen verwendet. Ein Beispiel hierfür ist die Verwendung flächiger Dachmodule aus Aluminium, welche mit einer Karosserie aus Stahlblech gefügt werden müssen.In order to reduce weight - and thus reduce fuel consumption with CO 2 emissions - in the body construction of passenger cars increasingly combinations of steel and light metal components are used. An example of this is the use of flat roof modules made of aluminum, which must be joined with a body of sheet steel.
Solche Kombinationen aus unterschiedlichen Werkstoffen sind mit dem Nachteil behaftet, dass die jeweiligen Werkstoffe unterschiedliche Wärmeausdehnungskoeffizienten aufweisen. Bei hoher thermischer Belastung der Bauteile kann es daher zu Verzügen kommen, welche die gewünschte Maßhaltigkeit beeinträchtigen. Ein Beispiel hierfür ist der Lackierprozess, in welchem die Bauteile bzw. Bauteilkombinationen nach dem kathodischen Tauchlackieren im sogenannten KTL-Ofen bei etwa 190°C und im sogenannten Decklack-Ofen bei etwa 100°C behandelt werden.Such Combinations of different materials are with the disadvantage Afflicted that the respective materials have different thermal expansion coefficients exhibit. At high thermal stress of the components it can therefore to delay come, which the desired dimensional stability affect. An example of this is the painting process, in which the components or component combinations after cathodic dip painting in the so-called KTL furnace at about 190 ° C and be treated in the so-called topcoat oven at about 100 ° C.
Aufgabe der vorliegenden Erfindung ist es somit, ein Verfahren der eingangs genannten Art so weiterzubilden, dass unterschiedliche Wärmeausdehnungen von Bauteilen aus verschiedenen Materialien besser kompensiert werden können und so Verzüge vermieden werden können.task The present invention is thus a method of the above so-called type so that different thermal expansions components made of different materials are better compensated can and so delays can be avoided.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst.These The object is achieved by a method having the features of the patent claim 1 solved.
Im Rahmen eines derartigen Verfahrens zum Montieren eines Dachmoduls einer Karosserie eines Kraftwagens wird zunächst das Dachmodul lösbar an einem Karosseriebauteil mittels wenigstens eines ersten Befestigungsmittels in einer Lackierposition befestigt. Im folgenden Verfahrensschritt werden Dachmodul und Karosserie gemeinsam lackiert. Erst nach dem Lackieren wird das Dachmodul an dem Karosseriebauteil mittels des wenigstens einen ersten Befestigungsmittels und einer zusätzlichen Verklebung endgültig befestigt. Die lösbare Befestigung des Dachmoduls an dem Karosseriebauteil vor und während des Lackierens ermöglicht dabei vorteilhaft das Durchführen des Lackierprozesses und insbesondere der Wärmebehandlungsschritte, ohne dass es zu Wärmeverzügen kommt.in the Frame of such a method for mounting a roof module a body of a motor vehicle, the roof module is first releasably connected to a Body component by means of at least a first fastening means attached in a painting position. In the following process step Roof module and body are painted together. Only after Painting the roof module on the body component by means of at least a first fastening means and an additional Bonding final attached. The detachable Mounting the roof module to the bodywork component before and during the Painting possible while doing the advantageous the painting process and in particular the heat treatment steps, without that there is heat distortion.
Das wenigstens eine erste Befestigungsmittel ist dabei bevorzugt als Schraube ausgebildet und wird vorzugsweise so angebracht, dass es einen Flansch des Karosseriebauteils durchsetzt. Bei dem Karosseriebauteil handelt es sich vorzugsweise um einen aus Stahlblech ausgebildeten Dachrahmenträger, wobei ein Flanschbereich der Außenschale des Dachrahmenträgers als Befestigungsort für die Schraube dienen kann. Das Dachmodul selbst besteht aus Aluminiumblech und wird in einer bevorzugten Ausführungsform der Erfindung mittelbar über ein Aufnahmeelement mit dem Befestigungsmittel, also bevorzugt der Schraube, verbunden. Das Befestigungsmittel kann dabei beispielsweise als Blechbauteil ausgeführt sein, welches mit einem Endbereich mit dem Dachmodul und mit einem weiteren Endbereich mit dem Befestigungsmittel verbindbar ist.The at least one first fastening means is preferred as Screw is formed and is preferably attached so that it passes through a flange of the body component. In the bodywork component it is preferably a formed of sheet steel Roof frame carrier, wherein a flange portion of the outer shell of the roof frame carrier as a place of attachment for the screw can serve. The roof module itself is made of aluminum sheet and in a preferred embodiment of the invention indirectly via a receiving element with the fastening means, so preferably the screw connected. The fastener may, for example, as a sheet metal component accomplished be, which with an end area with the roof module and with a another end region is connectable to the fastening means.
In einer weiteren bevorzugten Ausführungsform des Verfahrens wird beim Befestigen in Schritt a) und/oder c) ein Abstandselement zum Einstellen eines vorgegebenen Spaltmaßes zwischen Dachmodul und Karosseriebauteil eingebracht. Das Einbringen eines solchen Abstandselementes vor dem Lackieren minimiert die Kontaktstellen zwischen Dachmodul und Karosserie, so dass der durch das Abstandselement erzeugte Spalt von Lack durchspült werden kann. Damit ergibt sich eine besonders gleichmäßige Lackierung von sonst schlecht zugänglichen Bereichen des Dachmoduls und der Karosserie, was den Korrosionsschutz der jeweiligen Bauteile verbessert. Die Verwendung eines Abstandselementes bei der endgültigen Montage des Dachmoduls ermöglicht das Einstellen eines definierten Spaltmaßes zwischen Dachmodul und Karosserie, so dass beim Verkleben der beiden Bauteile eine besonders gleichmäßige Klebstoffdicke erreicht wird. Weiterhin wird so die Maßhaltigkeit insgesamt verbessert.In a further preferred embodiment of the method is inserted in the fastening in step a) and / or c) Distance element for setting a predetermined gap between Roof module and body component introduced. The introduction of a such spacer element prior to painting minimizes the contact points between the roof module and the body, so that by the spacer element be generated rinsed gap of paint can. This results in a particularly uniform finish of otherwise poor accessible Areas of the roof module and the body, giving the corrosion protection the respective components improved. The use of a spacer at the final Mounting the roof module allows the setting of a defined gap between the roof module and Body, so that when bonding the two components a particularly uniform adhesive thickness is reached. Furthermore, the dimensional stability is improved overall.
In einer weiteren bevorzugten Ausführungsform des Verfahrens wird in einem zusätzlichen Schritt b1) das Dachmodul von der Karosserie demontiert und wenigstens eine weitere Dachkomponente an das Dachmodul montiert. Dies ermöglicht die einfache Montage von Komponenten, welche selbst nicht lackierbar sind an das bereits lackierte Dachmodul.In a further preferred embodiment of the procedure becomes in an additional step b1) dismantled the roof module from the body and at least one additional roof component mounted to the roof module. This allows the easy installation of components, which themselves can not be painted are to the already painted roof module.
Zugänglichkeitsprobleme, welche sich bei einem vor dem Lackieren fest mit der Karosserie verbundenen Dachmodul ergeben, werden so vermieden.Accessibility problems which is fixed to the body before painting connected roof module, are thus avoided.
Bevorzugter Weise ist die Lackierposition des Dachmoduls relativ zur Karosserie verschieden von der Endmontageposition. Insbesondere unterscheiden sich Lackierposition und Endmontageposition bezüglich eines Spaltmaßes zwischen Dachmodul und Karosseriebauteil. Damit können für die unterschiedlichen Anforderungen bezüglich des Spaltmaßes beim Lackiervorgang und beim Verkleben für die Endmontage jeweils angepasste Spaltmaße gewählt werden.preferred Way is the painting position of the roof module relative to the body different from the final assembly position. In particular, differentiate Painting position and final assembly position with respect to a gap between Roof module and body component. This allows for the different requirements in terms of the gap dimension adapted during painting and bonding for final assembly respectively clearances chosen become.
Im Folgenden soll die Erfindung und ihre Ausführungsformen anhand der Zeichnungen näher erläutert werden. Hierbei zeigen:In the following, the invention and its Embodiments will be explained in more detail with reference to the drawings. Hereby show:
