Abstract
Description
Die vorliegende Erfindung betrifft ein Stützelement, insbesondere einen Dachspriegel, für eine Kraftfahrzeugkarosserie.The present invention relates to a support element, in particular a roof bow, for a motor vehicle body.
Um sich fortlaufend verschärfende gesetzliche Anforderungen an den Kraftstoffverbrauch der Kraftfahrzeuge erfüllen zu können, sind drastische Maßnahmen zur Gewichtsreduzierung der Fahrzeuge erforderlich. Da eine solche Gewichtsreduzierung nicht zu Lasten der Insassensicherheit gehen darf, kann sie nur erreicht werden, indem in den Kraftfahrzeugkarosserien neuartige Bauelemente eingesetzt werden, die die erforderliche strukturelle Stabilität der Fahrzeugkarosserie bei geringem Gewicht erreichen.In order to meet increasingly stringent legal requirements for the fuel consumption of motor vehicles, drastic measures to reduce the weight of vehicles are required. Since such weight reduction must not be at the expense of occupant safety, it can only be achieved by novel components are used in the motor vehicle bodies, which achieve the required structural stability of the vehicle body with low weight.
Es ist z. B. in
Eine Aufgabe der vorliegenden Erfindung ist, ein Stützelement für eine Kraftfahrzeugkarosserie zu schaffen, das eine anhaltend hohe Belastbarkeit bei minimalem Gewicht garantiert.An object of the present invention is to provide a support member for a vehicle body, which guarantees a long-lasting high load capacity with minimum weight.
Die Aufgabe wird gelöst, indem bei einem Stützelement, insbesondere einem Dachspriegel, für eine Kraftfahrzeugskarosserie, das wenigstens ein Schalenteil und eine in einem Hohlraum des Schalenteils spritzgeformte Versteifungsstruktur aus Kunststoff umfasst, das Schalenteil aus einem Organoblech gefertigt ist. Die Bezeichnung Organoblech wird verwendet für plattenförmige Verbundwerkstoffe, bei denen ein Gewebe, z. B. aus Glas-Kohle- oder Kunststofffasern, in eine thermoplastische Matrix eingebettet ist. Organoblech kann wie Metallblech zugeschnitten und gelocht werden, und wenn seine thermoplastische Matrix ausreichend erwärmt ist, kann es wie Metallblech, allerdings unter Einsatz kleinerer Verformungskräfte und dementsprechend leichterer und preiswerterer Maschinerie, dreidimensional verformt werden.The object is achieved by the shell part is made of an organic sheet in a support member, in particular a roof bow, for a motor vehicle body comprising at least one shell part and a plastic injection molded in a cavity of the shell part stiffening structure. The term organo sheet is used for plate-shaped composite materials in which a tissue, for. B. glass-carbon or plastic fibers, embedded in a thermoplastic matrix. Organo sheet can be cut and punched like sheet metal, and if its thermoplastic matrix is sufficiently warmed, it can be three dimensionally deformed like sheet metal, using smaller deformation forces and correspondingly lighter and cheaper machinery.
Da die Oberfläche des Organoblechs aus Kunststoff besteht, entfällt das Problem, eine dauerhafte Metall-Kunststoff-Verbindung zu schaffen. Eine besonders innige Verbindung zwischen den Kunststoffmaterialien des Organoblechs und des Schalenteils kann erhalten werden, wenn das Schalenteil ein Matrixmaterial aufweist, welches durch das Spritzformen der Versteifungsstruktur anschmelzbar ist. Dies ist insbesondere dann der Fall, wenn das Matrixmaterial und das Material der Versteifungsstruktur gleich sind.Since the surface of the organic sheet is made of plastic, eliminates the problem of creating a durable metal-plastic compound. A particularly intimate connection between the plastic materials of the organic sheet and the shell part can be obtained if the shell part has a matrix material, which can be melted by the injection molding of the stiffening structure. This is especially the case when the matrix material and the material of the stiffening structure are the same.
Anders als bei einem Metall-Kunststoff-Verbund ist das Recycling des Stützelements einfach, da Matrix und Fasern durch Schmelzen der Matrix oder geeignete Lösungsmittel voneinander getrennt werden können. Auch hierfür ist es zweckmäßig, wenn die Materialien von Matrix und Versteifungsstruktur dieselben sind oder zumindest weitgehend gleiche Inhaltsstoffe enthalten.Unlike a metal-plastic composite, the recycling of the support member is easy since the matrix and fibers can be separated by melting the matrix or suitable solvents. Again, it is useful if the materials of matrix and stiffening structure are the same or contain at least largely the same ingredients.
Ein fester Zusammenhalt zwischen Schalenteil und Versteifungsstruktur kann ferner dadurch gefördert werden, dass das Schalenteil von der Versteifungsstruktur durchsetzte Durchbrüche aufweist.A firm cohesion between the shell part and the stiffening structure can also be promoted by the fact that the shell part has breakthroughs penetrated by the stiffening structure.
Vorzugsweise ist die Versteifungsstruktur an diesen Durchbrüchen formschlüssig verankert, insbesondere, indem sie sich auf beiden Seiten des Schalenteils über die Ränder des Durchbruchs hinaus erstreckt.Preferably, the stiffening structure is positively anchored to these openings, in particular by extending beyond the edges of the opening on both sides of the shell part.
Eine hohe Belastbarkeit der Versteifungsstruktur bei geringem Gewicht ist erreichbar, wenn diese den Hohlraum des Schalenteils kreuzende Rippen aufweist.A high load capacity of the stiffening structure with low weight can be achieved if this has the cavity of the shell part crossing ribs.
Um die von diesen Rippen aufgenommenen Kräfte effizient in das Schalenteil einzuleiten, sollten wenigstens einige der Durchbrüche an den Enden dieser Rippen angeordnet sein.In order to efficiently introduce the forces absorbed by these ribs into the shell part, at least some of the apertures should be located at the ends of these ribs.
Die Versteifungsstruktur kann insbesondere ein Fachwerk von einander kreuzenden Rippen umfassen.In particular, the stiffening structure may comprise a framework of intersecting ribs.
In diesem Fall ist es für eine effiziente Kraftübertragung zwischen Schalenteil und Versteifungsstruktur ferner zweckmäßig, wenn wenigstens einige der Durchbrüche an Kreuzungspunkten der Rippen angeordnet sind.In this case, it is also expedient for an efficient transmission of force between the shell part and stiffening structure, if at least some of the apertures are arranged at crossing points of the ribs.
Um die Versteifungsstruktur in dem Schalenteil spritzformen zu können, sollte der Hohlraum des Schalenteils einseitig offen sein. Bei einem langgestreckten Schalenteil kann der Hohlraum daher zweckmäßigerweise die Form einer Rinne haben. In order to injection mold the stiffening structure in the shell part, the cavity of the shell part should be open on one side. In an elongated shell part, therefore, the cavity may conveniently have the shape of a groove.
Beiderseits der Rinne können sich langgestreckte Flansche anschließen, die zusammen mit der Rinne einen hutförmigen Querschnitt des Schalenteils bilden. Die Flansche dienen zweckmäßigerweise zur Befestigung eines oder mehrerer gestützter Karosserieteile an dem Stützelement.On both sides of the channel can elongated flanges join, which together with the groove form a hat-shaped cross-section of the shell part. The flanges are expediently used to attach one or more supported body parts to the support element.
Eine in Längrichtung des Schalenteils verlaufende Sicke kann zu dessen Tragfähigkeit beitragen. Andererseits kann die Sicke auch einen Kleber zur Befestigung eines von dem Stützelement gestützten Karosserieteils aufnehmen. Eine solche Sicke kann in jedem der oben erwähnten Flansche gebildet sein, aber auch in der Rinne selbst.A running in the longitudinal direction of the shell part bead can contribute to its capacity. On the other hand, the bead can also receive an adhesive for fastening a body part supported by the support element. Such a bead may be formed in each of the above-mentioned flanges, but also in the groove itself.
Ein an das Schalenteil angefügtes metallisches Ansatzstück ermöglicht die Montage des Stützelements mit herkömmlichen Techniken wie etwa Nieten und insbesondere Schweißen an anderen, eventuell metallischen Teilen einer Kraftfahrzeugkarosserie.A metal extension piece attached to the shell part allows the mounting of the support element with conventional techniques such as rivets and in particular welding to other, possibly metallic parts of a motor vehicle body.
Eine feste Verbindung zwischen dem Ansatzstück und dem Schalenteil kann vorzugsweise dadurch hergestellt werden, dass Verbindungskörper sich durch miteinander überlappende Durchbrüche des Ansatzstücks und des Schalenteils erstrecken.A firm connection between the end piece and the shell part can preferably be produced by connecting bodies extending through overlapping openings of the end piece and the shell part.
Wenn diese Verbindungskörper einteilig mit der Versteifungsstruktur ausgebildet sind, können in einem einzigen Prozessschritt Schalenteil und Ansatzstück aneinander fixiert und die Versteifungsstruktur ausgebildet werden.If these connecting bodies are formed integrally with the stiffening structure, shell part and end piece can be fixed to one another and the stiffening structure can be formed in a single process step.
Weitere Merkmale und Vorteile der Erfindung werden deutlich anhand der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die beigefügten Figuren. Aus dieser Beschreibung und den Figuren gehen auch Merkmale der Ausführungsbeispiele hervor, die nicht in den Ansprüchen erwähnt sind. Solche Merkmale können auch in anderen als den hier spezifisch offenbarten Kombinationen auftreten. Die Tatsache, dass mehrere solche Merkmale in einem gleichen Satz oder in einer anderen Art von Textzusammenhang miteinander erwähnt sind, rechtfertigt daher nicht den Schluss, dass sie nur in der spezifisch offenbarten Kombination auftreten können; stattdessen ist grundsätzlich davon auszugehen, dass von mehreren solchen Merkmalen auch einzelne weggelassen oder abgewandelt werden können, sofern dies die Funktionsfähigkeit der Erfindung nicht in Frage stellt. Es zeigen:Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. From this description and the figures also show features of the embodiments, which are not mentioned in the claims. Such features may also occur in combinations other than those specifically disclosed herein. Therefore, the fact that several such features are mentioned in the same sentence or in a different type of textual context does not justify the conclusion that they can occur only in the specific combination disclosed; instead, it is generally to be assumed that it is also possible to omit or modify individual ones of several such features, provided this does not call into question the functionality of the invention.
