Description

Geschweißter Stahlleichtträger mit kastenförmigem Hohlquerschnitt Die Erfindung betrifft einen Stahlleichtträger mit kastenförmigem Hohlquerschnitt, der aus einem Metallband gebildet ist, dessen längsseitig verlaufende Enden in der Hauptbeanspruchungsebene liegen und miteinander verschweißt sind. Welded lightweight steel beam with a box-shaped hollow cross-section The invention relates to a lightweight steel beam with a box-shaped hollow cross-section, which is formed from a metal strip, the longitudinal ends of which in the Main stress level lie and are welded together.

Derartige Träger werden vielfach für Fahrgestellrahmen verwendet, wobei immer mehr die Forderung nach leichteren Rahmen bei gleichbleibenden Stabilitätswerten erhoben wird.Such carriers are widely used for chassis frames, there is more and more demand for lighter frames with constant stability values will be charged.

Um dieser Forderung durch Herstellung möglichst dünnwandiger Träger, die jedoch die notwendige Knickfestigkeit und Beulsteifigkeit aufweisen, weitgehend zu genügen, wird erfindungsgemäß vorgeschlagen, die längsseitigen Enden auf der Trägerseite der größten Beanspruchung durch Zug-oder Druckkräfte, materialanhäufend im Bereich eines symmetrisch oder auch asymmetrisch zur senkrechten Mittellinie des Trägers liegenden Abschnitts aufeinander zu legen.In order to meet this requirement by manufacturing the thinnest-walled carrier possible, which, however, have the necessary resistance to buckling and buckling, largely to meet, is proposed according to the invention, the longitudinal ends on the Carrier side subject to the greatest stress from tensile or compressive forces, accumulating material in the area of a symmetrical or asymmetrical to the vertical center line of the carrier lying section on top of each other.

Die asymmetrische Materialanhäufung stellt ein einfaches Mittel dar, um dem zusätzlichen Auftreten von Querkräften entgegenzuwirken. Zum andern gewährleistet das Aufeinanderliegen der längsseitigen Enden eine Vollschweißung ohne besondere Hilfsmittel, wie beispielsweise das Anbringen einer Unterlage während der Schweißung.The asymmetrical accumulation of material is a simple means of to counteract the additional occurrence of lateral forces. On the other hand, guaranteed the lying on one another of the longitudinal ends a full weld without special Aids, such as attaching a pad during welding.

In der Zeichnung sind zwei Ausführungsbeispiele eines Trägers mit kastenförmigem Hohlquerschnitt schematisch dargestellt, und zwar zeigt Fig. 1 einen Träger, bei dem die Materialanhäufung im Bereich eines Abschnitts a symmetrisch zur senkrechten Mittellinie liegt, während Fig. 2 einen Träger darstellt mit asymmetrischer Verteilung der Materialanhäufung.In the drawing, two embodiments of a carrier are with box-shaped hollow cross-section shown schematically, namely Fig. 1 shows a Carrier in which the accumulation of material in the area of a section a is symmetrical to the vertical center line, while Fig. 2 shows a carrier with asymmetrical Distribution of material accumulation.
