Abstract
Die Erfindung betrifft ein Profilteil als Karosseriekomponente eines Kraftfahrzeuges, das in zumindest zwei Bereiche unterteilt ist, von denen der erste Teilbereich ein ferritisches oder perlitisch-ferritisches Gefüge mit einer Festigkeit unter 850 MPa und der zweite Teilbereich ein martensitisches Werkstoffgefüge und eine Festigkeit über 1400 MPa aufweist. Um die Anwendbarkeit des Profilteils für andere Einsatzgebiete zu verbessern, wird vorgeschlagen, dass die beiden Bereiche entlang einer vertikal und/oder schräg verlaufenden Trennebene unterteilt sind.The invention relates to a profile part as a body component of a motor vehicle, which is divided into at least two areas, of which the first portion of a ferritic or pearlitic-ferritic microstructure with a strength below 850 MPa and the second portion has a martensitic material structure and a strength above 1400 MPa , In order to improve the applicability of the profile part for other applications, it is proposed that the two areas are divided along a vertically and / or inclined separating plane.
Description
Die Erfindung betrifft ein Profilteil als Karosseriekomponente eines Kraftfahrzeuges gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a profile part as a body component of a Motor vehicle according to the preamble of the claim 1.
Im Serienfahrzeugbau ist es üblich, Karosseriekomponenten entsprechend ihrer Belastung auszulegen. Um dies zu erreichen, werden Bleche mit unterschiedlichsten Festigkeiten und Werkstoffgefügen eingesetzt.in the Standard vehicle construction is common bodywork components interpreted according to their load. To achieve this, will be Sheets with different strengths and material structures used.

Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The Task is according to the invention with the features of claim 1.
Vorteilhafte Ausgestaltungen ergeben sich aus den Merkmalen der abhängigen Ansprüche.advantageous Embodiments result from the characteristics of the dependent Claims.
Die Erfindung betrifft ein Profilteil als Karosseriekomponente eines Kraftfahrzeuges, das anforderungsgerecht in verschiedene vertikal und/oder schräg getrennte Bereiche unterteilt ist. Ein erster Bereich besteht aus höchstfestem Stahl mit martensitischem Werkstoffgefüge und einer Festigkeit über 1400 MPa. Ein zweiter Bereich mit höherer Duktilität besteht aus einem ferritisch oder perlitisch/ferritischen Werkstoffgefüge mit einer Festigkeit unter 850 MPa. Die verschiedenen Festigkeitsbereiche dienen auch dazu, eine Fügbarkeit mittels mechanischer bzw. formschlüssiger Fügeverfahren wie z. B. Stanznieten, Clinchen usw. zu ermöglichen und gleichzeitig eine Crash- und Gewichtsoptimierung durchzuführen. Der duktile Bereich eignet sich für mechanische bzw. formschlüssige Fügeverfahren, während der höchstfeste Bereich eine Versteifung des Profilteils bewirkt.The The invention relates to a profile part as a body component of a Motor vehicle meeting the requirements in different vertical and / or obliquely separated areas is divided. One first area is made of highest strength steel with martensitic Material structure and a strength over 1400 MPa. A second area with higher ductility exists from a ferritic or pearlitic / ferritic material structure with a strength below 850 MPa. The different strength ranges serve also to a Fügbarkeit by means of mechanical or positive joining method such. Punched rivets, Clinching, etc. and at the same time a crash and weight optimization. The ductile area suitable for mechanical or positive locking Joining process, while the highest strength Area causes a stiffening of the profile part.
Das Profilteil kann in einem Warmumformprozess im direkten oder indirekten Herstellverfahren gefertigt und einer Wärmebehandlung unterzogen werden, um die entsprechenden Festigkeitswerte zu erreichen. Dabei können die Festigkeitsunterschiede sowohl durch die gezielte Wärmebehandlung einzelner Bauteilbereiche als auch über den Einsatz unterschiedlicher Stahlqualitäten mit Tailor-Welded-Blank-Platinen erreicht werden.The Profile part can in a hot forming process in direct or indirect Manufactured manufactured and subjected to a heat treatment, to achieve the appropriate strength values. It can the strength differences both through the targeted heat treatment individual component areas as well as the use of different Steel grades achieved with Tailor-Welded Blank blanks become.
Der Kern der Erfindung ist darin zu sehen, dass Profilteile, die eine wesentlich größere Längserstreckung als Quererstreckung aufweisen, mit einer Trennebene entlang ihrer Längserstreckung in die oben genannten Teilbereiche unterteilt ist.Of the The core of the invention is the fact that profile parts, the one much longer length than Transverse extent, with a parting plane along its longitudinal extent is divided into the above subareas.
Der zweite Bereich kann aufgrund seiner Duktilität mittels formschlüssiger Fügemethoden, wie Stanznieten oder Clinchen an benachbarte Bauteile gefügt sein.Of the second area can be due to its ductility by means of positive joining methods, such as punched rivets or clinching be joined to adjacent components.
Der erste Bereich kann aus höchstfestem Stahl gefertigt sein, so dass die Steifigkeit der gesamten Karosseriekomponente verbessert ist.Of the first area can be made of highest strength steel, so that improves the rigidity of the entire body component is.
In Abhängigkeit des Herstellungsverfahrens kann sich zwischen dem ersten und dem zweiten Bereich ein Übergangsbereich erstrecken. Die Breite des Übergangsbereichs kann beispielsweise bei Einsatz von Tailored-Welded-Blank-Platinen relativ gering sein.In Dependence of the manufacturing process can vary the first and the second area a transition area extend. The width of the transition area can be, for example when using Tailored Welded blank blanks be relatively low.
Bei gezielter Wärmebehandlung während des Umformens ergibt sich herstellungsbedingt ein breiterer Übergangsbereich.at targeted heat treatment during forming There is a broader transitional area due to the manufacturing process.
In einer bevorzugten Ausgestaltungsform kann das Profilteil eine Tailored-Welded-Blank-Platine sein.In In a preferred embodiment, the profile part can be a tailored-welded blank board be.
Eine bevorzugte Anwendung des erfindungsgemäßen Profilteil besteht als Schale an einer A-Säule. Der in Fahrtrichtung gesehen vordere Bereich ist dann als Bereich mit hoher Duktilität ausgebildet, während der hintere Bereich höchstfest ausgebildet ist. Dadurch kann die A-Säule im vorderen Bereich mit herkömmlichen Fügeverfahren gefertigt werden. Im hinteren Bereich der A-Säule bietet das martensitische Werkstoffgefüge ausreichend Steifigkeit zur Anbindung des Türscharniers.A preferred application of the profile part according to the invention exists as a shell on an A-pillar. The in the direction of travel seen front area is then as area with high ductility trained, while the rear area is extremely strong is trained. This allows the A-pillar in the front area be manufactured with conventional joining methods. At the back of the A-pillar offers the martensitic Material structure sufficient rigidity to connect the Door hinge.
Im Folgenden wird eine bevorzugte Ausgestaltungsform der Erfindung anhand der Zeichnung näher erläutert. Dabei zeigen:in the The following will be a preferred embodiment of the invention explained in more detail with reference to the drawing. Showing:
