Abstract

The invention relates to a body structure of a vehicle body (vehicle body structure 1) which is composed of several hollow profiles (3, 4, 5), whereby a through-opening (6) is recessed in a substantially closed hollow profiled area of the body structure, said through-opening reducing the rigidity thereof. In order to produce a lightweight body structure, a reinforcement piece (reinforcement shell 8) is provided for at least partially compensating the decrease in strength, said reinforcement piece spanning the through-opening (6) in a built-in position and being secured to the edge (7) of the through-opening (6).

Description

Rohbaustruktur einer Fahrzeugkarosserie Body-in-white structure of a vehicle body
Die Erfindung betrifft eine Rohbaustruktur einer Fahrzeugkarosserie der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a shell structure of a vehicle body of the type mentioned in the preamble of claim 1.
Aus dem Serienfahrzeug ist z. B. bei Mercedes-Benz-Kraftwagen der E-Klasse bekannt, ein Hohlprofil einer in Schalenbauweise ausgeführten Rohbaustruktur der Karosserie mit einer Durchtrittsöffnungen zu versehen. Über diese Durchtrittsöffnung ist bei der Herstellung der Rohkarosserie z. B. der vom Hohl- profil begrenzte Hohlraum für einen Schenkel einer Punkt- schweißzange zugänglich.From the series vehicle is, for. B. in Mercedes-Benz motor vehicles of the E-Class known to provide a hollow profile of a shell construction of the body structure of the body with a passage openings. About this passage opening in the manufacture of the body shell z. For example, the cavity delimited by the hollow profile is accessible to one leg of a spot welding gun.
Die Schwächung des ansonsten weitgehend geschlossenen Hohl- profils an der Durchtritts ffnung bewirkt eine Verschlechterung der Festigkeit und Steifigkeit der Rohbaustruktur, so dass in der Regel Kompensationsmaßnahmen notwendig sind. Hierzu ist eine Erhöhung der Blechdicken der an die Durchtrittsöffnung angrenzenden Rohbauteile üblich.The weakening of the otherwise largely closed hollow profile at the passage opening causes the strength and rigidity of the bodyshell structure to deteriorate, so that compensation measures are generally necessary. For this purpose, an increase in the sheet thicknesses of the raw components adjacent to the passage opening is common.
Aufgabe der Erfindung ist es, eine Rohbaustruktur einer Fahrzeugkarosserie der im Oberbegriff des Anspruchs 1 genannten Art dahingehend weiterzuentwickeln, dass eine besonders Gewicht sparende Bauweise der Rohbaustruktur ermöglicht ist.The object of the invention is to further develop a bodyshell structure of a vehicle body of the type mentioned in the preamble of claim 1 in such a way that a particularly weight-saving design of the bodyshell structure is made possible.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst .This object is achieved according to the invention by the features of claim 1.
Weitere die Erfindung in vorteilhafter Weise ausgestaltende Merkmale enthalten die Unteransprüche. Der mit der Erfindung erzielte Vorteil besteht darin, dass der Querschnitt des Hohlprofils an der Durchtrittsöffnung zumindest bereichsweise durch ein mittragendes Verstärkungs- teil geschlossen ist, wodurch auf weitere Kompensationsmaßnahmen verzichtet werden kann.Further features which advantageously design the invention contain the subclaims. The advantage achieved by the invention is that the cross-section of the hollow profile at the passage opening is closed at least in regions by a supporting reinforcing part, which means that further compensation measures can be dispensed with.
Das Verstärkungsteil ist besonders zur Verstärkung einer Durchtrittsöffnung geeignet, die in einem sehr stark beanspruchten Bereich nahe eines Knotens der Rohbaustruktur angeordnet ist.The reinforcement part is particularly suitable for reinforcing a passage opening which is arranged in a very heavily used area near a node of the bodyshell structure.
Zur besonders steifen und gleichmäßigen Anbindung kann das Verstärkungsteil mit dem Öffnungsrand der Durchtrittsöffnung durch Klebung verbunden sein. Um dabei das Verstärkungsteil bei der Montage bis zum vollständigen Aushärten der Klebung auf einfache Weise an der Rohbaustruktur zu fixieren, kann zusätzlich zur Klebeverbindung ein Punktbefestigungsmittel vorgesehen sein.For a particularly rigid and uniform connection, the reinforcement part can be connected to the opening edge of the passage opening by gluing. In order to fix the reinforcement part to the body-in-white structure in a simple manner during assembly until the adhesive has fully hardened, a point fastening means can be provided in addition to the adhesive connection.
Zur Ermöglichung einer besonders montagefreundlichen Bauweise der Rohbaustruktur können mehrere einander benachbarte Durchtrittsöffnungen von einem gemeinsamen Verstärkungsteil überspannt sein.To enable a particularly easy-to-assemble construction of the shell structure, a plurality of mutually adjacent passage openings can be spanned by a common reinforcement part.
Das Verstärkungsteil kann besonders materialsparend auf den Umfang des Öffnungsrands der Durchtrittsöffnung abgestimmt sein.The reinforcing part can be matched to the circumference of the opening edge of the passage opening in a particularly material-saving manner.
Zur weiteren Gewichtsoptimierung der Rohbaustruktur kann das Verstärkungsteil eine Verstärkungsschale aus Faserverbundwerkstoff sein. Um dabei den Ausgleich von Karosserietoleranzen bei der Montage der Verstärkungsschale zu erleichtern, kann die Verstärkungsschale bei ihrer Montage in begrenztem Umfang widerstandsarm verformbar sein.To further optimize the weight of the bodyshell structure, the reinforcement part can be a reinforcement shell made of fiber composite material. In order to facilitate the compensation of body tolerances when installing the reinforcement shell, the reinforcement shell can be deformed to a limited extent with little resistance when it is installed.
Nachfolgend werden Ausführungsbeispiele der Erfindung anhand einer zeichnerischen Darstellung näher erläutert. In der Darstellung zeigen:Exemplary embodiments of the invention are explained in more detail below with the aid of a drawing. The illustration shows:
Fig. 1 eine Kraftwagenrohkarosserie im Bereich eines hinteren Dachknotens in einer perspektivischen Ansicht von innen undFig. 1 shows a motor vehicle body in the area of a rear roof node in a perspective view from the inside and
Fig. 2 den vorderen Bereich einer zweiten Kraftwagenrohkarosserie mit zwei vorderen Dachknoten ebenfalls in einer perspektivischen Ansicht von innen.Fig. 2 shows the front area of a second motor vehicle body with two front roof nodes also in a perspective view from the inside.
In Fig. 1 ist von der Rohkarosserie 1 eines Kraftwagens der Mercedes-Benz E-Klasse nur ein Bereich um einen hinteren linken Dachknoten 2 dargestellt, an dem ein seitlicher Dachholm 3, ein hinterer Dachquerträger 4 sowie eine C-Säule 5 aufeinander stoßen.In Fig. 1 of the body shell 1 of a motor vehicle of the Mercedes-Benz E-Class is shown only an area around a rear left roof node 2, on which a side roof spar 3, a rear roof cross member 4 and a C-pillar 5 meet.
Der Dachholm 3, der Dachquerträger 4 und die C-Säule 5 sind als geschlossene Hohlträger ausgebildet und in üblicher Schalenbauweise aus tiefgezogenen Stahlblechteilen hergestellt, die durch Punktschweißen miteinander verbunden sind.The roof spar 3, the roof cross member 4 and the C-pillar 5 are designed as closed hollow beams and are produced in a conventional shell construction from deep-drawn sheet steel parts which are connected to one another by spot welding.
An der Innenseite des Dachknotens 2 ist eine etwa ovale Durchtrittsöffnung 6 ausgebildet, über welche bei Herstellung der Rohkarosserie 1 der vom Dachholm 3, dem Dachquerträger 4 und der C-Säule 5 begrenzte Hohlraum für einen Schenkel einer üblichen Punktschweißzange zugänglich ist, um Blechteile an der Außenseite des Dachknotens 2 zu verschweißen.On the inside of the roof node 2, an approximately oval passage opening 6 is formed, through which the hollow space delimited by the roof rail 3, the roof cross member 4 and the C-pillar 5 for a leg of a conventional spot welding gun is accessible to sheet metal parts on the in the manufacture of the body shell 1 To weld the outside of the roof node 2.
Die Durchtrittsöffnung 6 ist von einem Öffnungsrand 7 umschlossen, der von der Innenwand der C-Säule 5 und der Innenwand des Dachquerträgers 4 gebildet ist. Der Öffnungsrand 7 und die Durchtrittsöffnung 6 sind vollständig von einer Verstärkungsschale 8 überdeckt, die mit dem Öffnungsrand 7 vollflächig verklebt ist. Die dünnwandige Verstärkungsschale 8 ist aus einem Faserverbundwerkstoff hergestellt und umfasst eine Kunststoffmatrix mit einer eingelegten Fasermatte, deren Fasern ungerichtet angeordnet sind. Alternativ können die Fasern in Anpassung an die örtlich auftretenden Belastungen in einer Vorzugsrichtung verlaufen sein.The passage opening 6 is enclosed by an opening edge 7, which is formed by the inner wall of the C-pillar 5 and the inner wall of the roof cross member 4. The opening edge 7 and the passage opening 6 are completely covered by a reinforcing shell 8 which is glued to the opening edge 7 over the entire surface. The thin-walled reinforcement shell 8 is made of a fiber composite material and comprises a plastic matrix with an inserted fiber mat, the fibers of which are arranged in a non-directional manner. Alternatively, the Fibers must have run in a preferred direction to match the local loads.
In einer besonders einfachen und kostengünstigen Ausführung kann auch eine Verstärkungsschale aus Stahlblech vorgesehen sein, die mit dem Öffnungsrand 7 der Durchtrittsöffnung 6 z. B. durch Klebung oder Kehlschweißung verbunden ist.In a particularly simple and inexpensive embodiment, a reinforcing shell made of sheet steel can also be provided, which with the opening edge 7 of the passage opening 6 z. B. is connected by gluing or fillet welding.
Bei der Herstellung der Rohkarosserie 1 werden zunächst die Blechteile in üblicher Weise durch Punktschweißen miteinander verbunden. Anschließend wird die Verstärkungsschale 8 in einem umfangsnahen Bereich mit einer Kleberschicht versehen und gemäß ihrer Einbaulage am Öffnungsrand 7 der Durchtrittsöffnung 6 ausgerichtet. Die Kunststoffmatrix der Verstärkungsschale 8 ist durch einen Kunststoff gebildet, der zum Zeitpunkt der Montage der Verstärkungsschale 8 noch nicht vollständig ausgehärtet ist, so dass die Verstärkungsschale 8 zum Ausgleich von Karosserietoleranzen in begrenztem Umfang widerstandsarm verformbar ist.In the manufacture of the body-in-white 1, the sheet metal parts are first connected to one another in the usual manner by spot welding. Subsequently, the reinforcement shell 8 is provided with an adhesive layer in a region close to the circumference and aligned according to its installation position at the opening edge 7 of the passage opening 6. The plastic matrix of the reinforcement shell 8 is formed by a plastic which is not yet fully cured at the time the reinforcement shell 8 is installed, so that the reinforcement shell 8 can be deformed to a limited extent with little resistance to compensate for body tolerances.
Danach wird die Verstärkungsschale 8 durch Anpressen mit dem Öffnungsrand 7 der Durchtrittsöffnung 6 vollflächig verklebt. Durch die Erwärmung während der anschließenden kathodischen Tauchlackierung der Rohkarosserie 1 härten sowohl die Klebe- Verbindung als auch die Kunststoffmatrix der Verstärkungsschale 8 aus .Thereafter, the reinforcement shell 8 is glued over the entire surface by pressing with the opening edge 7 of the passage opening 6. As a result of the heating during the subsequent cathodic dip coating of the body-in-white 1, both the adhesive connection and the plastic matrix of the reinforcement shell 8 harden.
Um bis zum vollständigen Aushärten von Kleber und Kunststoffmatrix eine zuverlässige Fixierung der Verstärkungsschale 8 in ihrer Einbaulage zu gewährleisten, kann diese zusätzlich über Niet-, Clinch oder Schraubverbindungen am Öffnungsrand 7 der Durchtrittsöffnung 6 festgelegt sein.In order to ensure that the reinforcement shell 8 is reliably fixed in its installed position until the adhesive and plastic matrix have completely hardened, it can additionally be fixed to the opening edge 7 of the passage opening 6 via rivet, clinch or screw connections.
Falls die Durchtrittsöffnung 6 zum Ablauf des Lacks während der Tauchlackierung freigehalten werden muss, kann die Verstärkungsschale 8 erst nach Lackierung der Rohkarosserie 1 in der oben beschriebenen Weise montiert werden. Dabei kann zur Aushärtung der Klebung und der Kunststoffmatrix der Verstärkungsschale 8 entweder der Lackierung eine Wärmebehandlung der Rohkarosserie 1 in einem Wärmeofen nachgeschaltet sein, oder über eine entsprechende Auswahl des Kleber- und Kunst- stoffmaterials eine Aushärtung nach der Lackierung bei Raumtemperatur vorgesehen sein.If the passage opening 6 has to be kept clear for the lacquer to run off during the dip coating, the reinforcement shell 8 can only be fitted in the manner described above after the body shell 1 has been coated. It can Hardening of the adhesive and the plastic matrix of the reinforcement shell 8 can either be followed by a heat treatment of the body-in-white 1 in a heating furnace after the painting, or a hardening after the painting can be provided at room temperature after the painting.
