Description

Die Erfindung bezieht sich auf eine Verbesserung und weitere Ausbildung des Gegenstandes des Hauptpatents 897 953.The invention relates to an improvement and further development the subject matter of the main patent 897 953.

Gegenstand des Hauptpatents ist ein Träger, insbesondere für Kraftfahrzeuge, der aus zwei ineinander oder mehreren in einem gemeinsamen Außenrohr nebeneinander angeordneten Rohren besteht.The subject of the main patent is a carrier, in particular for motor vehicles, that of two inside each other or several side by side in a common outer tube arranged tubes consists.

Dieser Haupterfindungsgedanke hat gemäß der Zusatzerfindung dadurch eine Verbesserung und weitere Ausbildung erfahren, daß vier, aus je zwei Streifen gebildete Einzelhohlträgerelemente vorgesehen werden, die mit Hilfe von an diesen Elementen vorgesehenen Randflanschen zu einem Gesamtträger zusammengeführt werden. Auf diese Weise entsteht auch ein Träger, der nach dem Zusammenbau aus mehreren neben- und ineinanderliegenden Rohren aufgebaut ist. Die Verbesserung und@weitere Ausbildung besteht hierbei darin, daß die Rohre aus Einzelhohlträgerelementen zusammengesetzt sind, wodurch sich herstellungstechnisch beachtliche Vorteile ergeben, zumal die Einzelhohlträgerelemente durch Walzen leichter herstellbar sind als ganze Rohre.According to the additional invention, this main inventive concept has thereby an improvement and further training experience that four, out of two strips formed single hollow support elements are provided with the help of these Elements provided edge flanges are brought together to form an overall beam. In this way, a carrier is also created, which after assembling from several adjacent and nested tubes is constructed. The improvement and @ others Training consists in the fact that the tubes are composed of individual hollow support elements are, which results in considerable advantages in terms of production, especially the Individual hollow girder elements can be produced more easily than whole tubes by rolling.

In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar zeigen die Bilder fünf verschiedene Ausführungsformen eines Trägers gemäß der Erfindung.In the drawing, the invention is illustrated, for example, the pictures show five different embodiments of a carrier according to FIG the invention.

In den Bildern sind mit d im wesentlichen rechtwinklige Streifen bezeichnet, die in den Bildern i bis 3 durch flache Platten b zu Einzelelementen zusammengefügt sind, die nach der Zusammenfügung die Querschnittsform eines rechtwinkligen Dreiecks aufweisen. Vier dieser Einzelelemente ergeben zusammen einen Hohlträger, der aus einem äußeren im wesentlichen rechteckigen oder quadratischen und einem inneren rhombischen oder quadratischen Hohlträger besteht.In the pictures, d essentially denotes right-angled stripes, those in Figures i to 3 joined together by flat panels b to form individual elements are which, when assembled, have the cross-sectional shape of a right triangle exhibit. Four of these individual elements together result in a hollow beam that consists of an outer substantially rectangular or square and an inner one rhombic or square hollow beam.

In Bild i erstrecken sich die Flansche ä , b' der Einzelelemente über den Umfang des rechteckigen Gesamtträgers nach außen.In picture i, the flanges ä , b 'of the individual elements extend outward over the circumference of the rectangular overall beam.

In Bild :2 sind die Flansche d, b' so in das Innere des Profils des Gesamtträgers eingezogen, daß sie nicht über den Umfang dieses Trägers hinausragen.In Fig. 2, the flanges d, b ' are drawn into the interior of the profile of the entire girder so that they do not protrude beyond the circumference of this girder.

In Bild 3 sind die Flansche ä so angeordnet, daß sie an den Platten b unmittelbar und nicht an den Flanschen b' dieser Platten befestigt werden. Die Flansche b' dieser Platten dienen lediglich zur Vereinigung der bereits zusammengesetzten Einzelelemente a, b zum Gesamtträger.In Figure 3 the flanges ä are arranged in such a way that they are attached directly to the plates b and not to the flanges b 'of these plates. The flanges b 'of these plates serve only to unite the already assembled individual elements a, b to form the overall carrier.

In Bild q. ist ein rechtwinkliger Streifen a entsprechend Bild i statt durch ein flaches Blech durch ein gekrümmtes Blech c abgeschlossen, so daß nach der Zusammensetzung von vier Einzelelementen ein Träger entsteht, der aus einem rechteckigen Außenträger und einem rohrförmigen Innenträger besteht.In picture q. is a right-angled strip a according to picture i instead completed by a flat sheet metal by a curved sheet c, so that after The combination of four individual elements creates a carrier that consists of one rectangular outer beam and a tubular inner beam.

In Bild 5 ist ein gekrümmtes Außenblech d durch ein flaches Blech b entsprechend Bild i abgedeckt, so daß nach der Zusammensetzung der vier Einzelelemente ein rohrförmiger Außenträger entsteht, in dem sich ein rechteckiger Innenträger befindet.In Figure 5 a curved outer sheet d is through a flat sheet b covered according to picture i, so that after the assembly of the four individual elements a tubular outer beam is created in which a rectangular inner beam is located is located.
