Abstract
Description
Die Erfindung betrifft ein Karosseriebauteil in Form von aus Metallblechen bestehenden Längs- und/oder Querträger, insbesondere in Form eines Schwellers.The The invention relates to a body component in the form of metal sheets existing longitudinal and / or Crossbeam, especially in the form of a sill.
Um
der Zunahme der Fahrzeuggewichte in Folge höherer Sicherheitsanforderungen
bezüglich der
Steifigkeit der Fahrgastzellen von Kraftfahrzeugen und ihrer Deformationseigenschaften
begegnen zu können
gelangen im Karosseriebau in zunehmenden Maße Leichtbauwerkstoffe, wie
z. B. Aluminiummetalle zum Einsatz. Wie die
Die auf solche Weise hergestellten Karosseriebauteile haben als Hohlprofile eine gute Formsteifigkeit und nehmen bei Verformen durch einen Aufprall viel Aufprallenergie auf.The manufactured in such a way body components have as hollow sections a good stiffness and take in deformation by impact a lot of impact energy.
Es ist auch bekannt als Karosseriebauteile dienende Hohlprofile durch Strangpressen herzustellen.It is also known as body parts serving hollow profiles Produce extrusions.
Der Erfindung liegt die Aufgabe zugrunde, die Formsteifigkeit solcher Karosseriebauteile weiter zu erhöhen bei gleichzeitiger Verbesserung von deren Aufbaufolge und der Möglichkeit der optimalen Anpassung an deren Einsatzbereiche im Karosseriebau.Of the Invention is based on the object, the dimensional stability of such Body parts continue to increase while improving their structure and possibility the optimal adaptation to their application in body construction.
Diese Aufgabe ist gemäß der Erfindung durch die Merkmale des Patentanspruches 1 gelöst.These Task is in accordance with the invention by the features of claim 1 solved.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further Features of the invention will become apparent from the dependent claims.
Infolge der erfindungsgemäßen Kombination von durch Rollformen von Metallblech gebildeten Profilteilen und dem Zusammenfügen dieser Teile durch Verbinden ihrer über die Profilhöhe hinausragenden flanschartigen Blechenden entsteht ein integrales mindestens zwei Kammern einschließendes Hohlprofil sehr hoher Steifigkeit und verbesserter Fähigkeit zur Aufnahme von Aufprallenergie. Gleichzeitig ermöglicht die erfindungsgemäße Ausbildung der Rollprofile aus gleichem oder unterschiedlichen Material, eine Verbesserung der Aufbaufolge von Längs- und/oder Querträgern einer solchen Karosserie, insbesonders bei ihrer Anwendung als Schweller. Es ist nunmehr eine optimale Anpassung der Profile an die unterschiedlichen Anforderungen hinsichtlich Aufnahme von Verformungsarbeit bei einem Aufprall und hinsichtlich geforderter Karosseriegestaltung der als Innen- und Außenschweller bezeichneten Teile eines solchen Schwellers einfacher als bisher möglich. Infolge der Anwendung der Rollverformung können die genannten Profilteile in ihrer Kontur beliebig ausgebildet sein, wobei lediglich dafür Sorge zu tragen ist, dass mindestens zwei bzw. drei Kammern von den rollverformten Metallblechen umfasst sind. Die Aufteilung des Gesamtprofils in mindestens zwei Profilteile ermöglicht ferner überraschend einfach durch unterschiedliche Gestaltung und unterschiedliche Wahl der Materialstärke deren optimale Anpassung an die Aufgaben, die z. B. an einen Innenschweller und an einen Außenschweller hinsichtlich zu gestaltender Struktur und angreifender Verformungskräfte einer damit ausgestatteten Karosserie gestellt werden. Dies gilt auch für die Verwendung als Längs- oder Quer- bzw. Sitzquerträger da auch hier eine Trennung zwischen Unterbau und Aufbau mit unterschiedlichen Materialien, z. B. Aluminium für den Aufbau und Stahl für den Unterbau, durchführbar ist.As a result the combination of by roll forming of sheet metal formed profile parts and the Put together these parts by connecting their projecting beyond the profile height flange-like sheet ends creates an integral at least two Chamber enclosing hollow profile very high stiffness and improved impact energy absorption capacity. At the same time allows the training of the invention the rolling profiles of the same or different material, one Improvement of the construction sequence of longitudinal and / or cross members of a Such bodywork, especially in its application as a sill. It is now an optimal adaptation of the profiles to the different Requirements for absorbing deformation work in one Impact and in terms of required body design of the interior as and outside skirts designated parts of such a sill easier than before possible. As a result of the application of roll deformation, the profile parts mentioned be formed arbitrarily in their contour, only care To carry is that at least two or three chambers of the rollformed Metal sheets are included. The distribution of the overall profile in allows at least two profile parts furthermore surprisingly simply by different design and different choice the material thickness their optimal adaptation to the tasks that z. B. to an inner skirts and to an outside sill regarding structure to be designed and attacking deformation forces of a equipped body are provided. this is also valid for the Use as longitudinal or Transverse or seat cross member because here too a separation between substructure and structure with different Materials, eg. B. aluminum for the construction and steel for the substructure, feasible is.
Schließlich kann das erfindungsgemäße Holprofil auch aus einem rollgeformten und aus einem stranggepressten Profilteil zusammen gefügt sein.Finally, can the Holprofil invention also from a roll-formed and from an extruded profile part be together.
Das erfindungsgemäße Profil bietet also viele Vorteile, insbesonders auch in der Anbindung an benachbarte Karosserieteile.The profile according to the invention offers many advantages, especially in the connection to neighboring Body parts.
