Abstract

A hollow member (3) for the body of motor vehicles consists of at least two sheet-metal profiles (5, 7), at least one of the edges facing one another being drawn inwards into the profile in order to form a groove for a weld seam or solder seam (15, 17). <IMAGE>

Description

Hohl träger für den Aufbau von Kraftfahrzeugen Hollow beams for the construction of motor vehicles

Die Erfindung bezieht sich auf einen Hohiträger für den Aufbau von Kraftfahrzeugen, welcher einen nicht konstanten Querschnitt aufweist und aus mindestens zwei, durch Schweißung oder Lötung miteinander verbundenen Blechprofilen zusammengesetzt ist.The invention relates to a hollow beam for the construction of Motor vehicles, which has a non-constant cross-section and at least two sheet metal profiles connected to one another by welding or soldering is.

Bekannte Blechprofile sind zu diesem Zweck mit Schweißflanschen versehen, welche nach außen vom eigentlichen Profilquerschnitt abstehen. Durch die Schweißflansche ist es möglich, die Blechprofile durch Punktschweißung miteinander zu verbinden. Die Schweißflansche vergrößern den Profilquerschnitt, ohne jedoch das Widerstandsmoment wesentlich zu erhöhen. Kleinere Profilquerschnitte sind jedoch im Fahrzeugbau aus verschiedenen Gründen erwünscht. Außerdem muß stets darauf geachtet werden, daß die Schweißflansche in einem Bereich angeordnet werden, in dem sie nicht störend in Erscheinung treten. Manchmal kann trotzdem nicht vermieden werden, daß separate Verkleidungen für die Schweißflansche erforderliche sind. Durch neue Verbindungstechniken (z. B Kleben) sind die Schweißflansche auch nicht mehr zum Aufschieben von Dichtungen notwendig. Bei einer einyeklebten Windschutzscheibe beispielsweise verkleinern die mit Schweißflanschen versehenen vorderen Dachsäulen den Sichtwinkel.Known sheet metal profiles are provided with welding flanges for this purpose, which protrude outwards from the actual profile cross-section. Through the welding flanges it is possible to connect the sheet metal profiles to one another by spot welding. The welding flanges enlarge the profile cross-section, but without the section modulus to increase significantly. Smaller profile cross-sections are, however, made in vehicle construction desired for various reasons. In addition, it must always be ensured that the welding flanges are arranged in an area in which they are not bothersome appear. Sometimes it can still not be avoided that separate Coverings for the welding flanges are required. With new connection technologies (e.g. gluing) the welding flanges are also no longer used for sliding on seals necessary. In the case of a glued-in windshield, for example, the Front roof pillars with welding flanges reduce the viewing angle.

Der Erfindung liegt die Aufgabe zugrunde, aus mindestens zwei Blechprofilen einen Hohl träger für den Aufbau von Kraftfahrzeugen so herzustellen, daß die Blechprofile ohne Ausbildung eines Schweißflansches miteinander verschweißt werden können.The invention is based on the object of at least two sheet metal profiles to produce a hollow support for the construction of motor vehicles so that the sheet metal profiles can be welded together without forming a welding flange.

Die Aufgabe wird dadurch gelöst, daß wenigstens einer der einander zugewandten Ränder der Blechprofile an ihrer Stoßstelle zur Bildung einer Kehle nach innen in das Profil eingezogen ist und die Kehle eine im Schweiß- oder Lötverfahren hergestellte Naht aufnimmt.The object is achieved in that at least one of each other facing edges of the sheet metal profiles at their joint to form a groove is drawn inwards into the profile and the fillet is a welding or soldering process picks up produced seam.

Durch den erfindungsgemäßen Hohlträger können sowohl offene als auch geschlossene Profile mit nicht konstantem Querschnitt kostengünstig hergestellt werden. Diese gänzlich neue Art von Hohlträger für den Aufbau von Kraftfahrzeugen ermöglicht die Realisierung kleinerer Querschnittsformen bei gleicher Festigkeit.With the hollow beam according to the invention, both open and closed profiles with non-constant cross-section produced inexpensively will. This completely new type of hollow beam for the construction of motor vehicles enables the realization of smaller cross-sectional shapes with the same strength.

Es besteht auch eine freiere Gestaltung des Profilquerschnitts, da nicht auf die Ausbildung von Schweißflanschen Rücksicht genommen werden muu. Wird die Schweiß~ bzw. Lötstelle nachbehandelt, dann ist es ohne weiteres möglich, daß diese Stelle auch eine Sichtfläche bildet.There is also a more free design of the profile cross-section, since the formation of welding flanges need not be taken into account. Will the welding or soldering point is aftertreated, then it is easily possible that this point also forms a visible surface.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben. Es zeigt Fig. 1 in perspektivischer Darstellunq schematisch eine Mittelsäule eines Personenkraftwagens und Fig. 2 den Schnitt 11-11 aus Fig. 1.An embodiment of the invention is shown in the drawing and is described in more detail below. It shows Fig. 1 in a perspective representation schematically a center column of a passenger car and FIG. 2 the section 11-11 from Fig. 1.

Eine in Fig. 1 gezeigte Mittelsäule 3 eines Personenkraftwagens weist in ihrer oberen Abschnitt den in Fig. 2 näher dargestellten Querschnitt auf.A center pillar 3 of a passenger car shown in FIG. 1 has in its upper section the cross section shown in more detail in FIG.

Die Mittelsäule 3 ist aus einem inneren Blechprofil 5 und einem äußeren Blechprofil 7 zusammengesetzt. Die Ränder 9 und 11 des inneren Blechprofils 5 sind um etwa 900 nach innen abgebogen.The center column 3 is made up of an inner sheet metal profile 5 and an outer one Sheet metal profile 7 composed. The edges 9 and 11 of the inner sheet metal profile 5 are bent inwards by about 900.

Der dem Rand 9 gegenüberliegende, ebenfalls nach innen umgebogen? Rand 13 des äußeren Blechprofils 7 bildet zusammen mit dem Rand 9 eine Kehle, welche eine beide Blechprofile verbindende Schweißnaht 15 aufnimmt.The one opposite the edge 9, also bent inwards? edge 13 of the outer sheet metal profile 7 forms together with the edge 9 a groove, which receives a weld 15 connecting both sheet metal profiles.

Eine zweite Schweißnaht 17, angeordnet an einer Ecke, wird von einer Kehle aufgenommen, welche durch den Rand 11 des inneren Blechprofils 5 und den gegenüberliegenden Rand 19 des äußeren Blechprofils 7 gebildet wird.A second weld seam 17, arranged at a corner, is of a Throat added, which through the edge 11 of the inner sheet metal profile 5 and the opposite Edge 19 of the outer sheet metal profile 7 is formed.
