Es ist ein Längsschnitt durch ein Verstärkungsrohr 5 im Bereich der Durchdringung durch einen Querträger 3 dargestellt. Eine Hülse 10 umschließt das Verstärkungsrohr 5 und führt es in einer Ausnehmung 6 des Querträgers 3. Diese Hülse 10 wird beim Zusammenbau des Untergestells 11 auf das 5 shows by way of example and schematically the passage of a reinforcing tube through a cross member. It is shown a longitudinal section through a reinforcing tube 5 in the region of penetration by a cross member 3. A sleeve 10 surrounds the reinforcing tube 5 and guides it in a recess 6 of the cross member 3. This sleeve 10 is in the assembly of the base 11 on the
Verstärkungsrohr 5 aufgeschoben und anschließend in die Reinforced tube 5 postponed and then in the
Ausnehmung 6 gedrückt. Dadurch wird das Verstärkungsrohr 5 spielfrei in der Ausnehmung 6 geführt, wodurch jegliche  Recess 6 pressed. As a result, the reinforcing tube 5 is guided without play in the recess 6, whereby any
Geräuschentwicklung unterbunden wird und aufgrund der Noise is prevented and due to the
verbesserten Führung des Verstärkungsrohres ein Ausknicken im Belastungsfall weiter verringert wird. improved guidance of the reinforcing tube buckling in case of load is further reduced.
Fig.6 zeigt beispielhaft und schematisch eine Hülse. Es ist die dreidimensionale Ansicht eines Schnitts durch eine Hülse 10 dargestellt. Diese einteilige Hülse 10 kann ebenso 6 shows by way of example and schematically a sleeve. The three-dimensional view of a section through a sleeve 10 is shown. This one-piece sleeve 10 may as well
zweiteilig hergestellt werden um sie auch nach erfolgtem Zusammenbau des Untergestells 11 montieren zu können. be prepared in two parts to assemble them even after the assembly of the base frame 11 can.
Fig.7 zeigt beispielhaft und schematisch ein Untergestell eines erfindungsgemäßen Schienenfahrzeugs bei Krafteinleitung aus dem Hauptquerträger. Es ist die Aufsicht auf ein 7 shows by way of example and schematically a subframe of a rail vehicle according to the invention when force is introduced from the main crossbeam. It is the supervision of one
Untergestell 11 eines Endes eines Schienenfahrzeugs dargestellt. Das andere Ende des Schienenfahrzeugs ist spiegelgleich aufgebaut. Das Untergestell 11 umfasst zwei Längsträger 1, mehrere Querträger 3, zwei Hauptquerträger 7 und zwei Kopfstücke 8. Die Längsträger 11 erstrecken sich über die gesamte Länge des Schienenfahrzeugs zwischen denUnderframe 11 of one end of a rail vehicle shown. The other end of the rail vehicle is mirror-like. The underframe 11 comprises two longitudinal members 1, a plurality of cross members 3, two main cross members 7 and two head pieces 8. The longitudinal members 11 extend over the entire length of the rail vehicle between the
Kopfstücken 8 und bilden zusammen mit den Querträgern 3 einen Rahmen. Die Querträger 3 sind horizontal geschnitten Head pieces 8 and together with the cross members 3 form a frame. The cross member 3 are cut horizontally
dargestellt. Zwischen den Hauptquerträgern 7 beider Enden des Untergestells 11 verlaufen zwei Verstärkungsrohre 5 in shown. Between the main cross beams 7 of both ends of the undercarriage 11 extend two reinforcing tubes 5 in
Längsrichtung des Schienenfahrzeugs. Diese Verstärkungsrohre 5 durchdringen die Querträger 3 in Ausnehmungen 6 dieser Querträger 3. Die Verstärkungsrohre 5 sind an den Stellen dieser Durchdringung nicht mit den Querträgern 3 verbunden. Zur Verdeutlichung dieses Merkmals gegenständlicher Erfindung sind die Ausnehmungen 6 übermäßig vergrößert dargestellt. In diese Ausnehmungen können, wie in Fig.5 gezeigt, Hülsen 10 eingeführt werden (nicht dargestellt) um die Führung der Verstärkungsrohre 5 zu verbessern und jegliche Longitudinal direction of the rail vehicle. These reinforcing tubes 5 penetrate the cross member 3 in recesses 6 of the cross member 3. The reinforcing tubes 5 are not connected to the cross members 3 at the points of this penetration. To clarify this feature of the present invention, the recesses 6 are shown enlarged excessively. In these recesses, as shown in Figure 5, sleeves 10 are inserted (not shown) to improve the guidance of the reinforcing tubes 5 and any
Geräuschentwicklung zu verhindern. An jedem Ende der To prevent noise. At each end of the
Verstärkungsrohre 5 ist eine Krafteinleitungsvorrichtung 12 vorgesehen, welche das Ende jedes Verstärkungsrohres 5 führt und die Druckkräfte von dem Hauptquerträger 7 in die Reinforcing tubes 5, a force introduction device 12 is provided, which leads the end of each reinforcing tube 5 and the pressure forces from the main cross member 7 in the
Verstärkungsrohre 5 einleitet. Die Ausführung dieser Reinforcing tubes 5 initiates. The execution of this
Krafteinleitungsvorrichtung 12 wird unter anderem von der Materialpaarung Verstärkungsrohr 5 zu Hauptquerträger 7 bestimmt. Sind diese Materialien miteinander verschweißbar, so empfiehlt es sich, sie an dieser Stelle zu verschweißen, wodurch die Krafteinleitungsvorrichtung 12 besonders einfach gestaltet werden kann. Force introduction device 12 is determined inter alia by the material pairing reinforcing tube 5 to main cross member 7. If these materials can be welded together, then it is recommended that they be welded at this point, whereby the force introduction device 12 can be made particularly simple.
Fig.8 zeigt beispielhaft und schematisch ein Untergestell eines erfindungsgemäßen Schienenfahrzeugs bei Krafteinleitung aus dem Kopfstück. Es ist das Untergestell 11 aus Fig.7 dargestellt, wobei die Krafteinleitung in die 8 shows by way of example and schematically a subframe of a rail vehicle according to the invention when force is introduced from the head piece. It is the base 11 of FIG represented, wherein the force introduction into the
Verstärkungsrohre 5 bereits aus dem Kopfstück 8 erfolgt. Die Verstärkungsrohre 5 verlaufen zwischen den Kopfstücken 8 der beiden Enden des Untergestells 11 und durchdringen neben den Querträgern 3 auch den Hauptquerträger 7. Zu Verdeutlichung ist der Hauptquerträger 7 dazu teilweise geschnitten Reinforcing tubes 5 already takes place from the head piece 8. The reinforcing tubes 5 extend between the head pieces 8 of the two ends of the undercarriage 11 and penetrate next to the cross members 3 and the main cross member 7. For clarity, the main cross member 7 is partially cut to
dargestellt. Es empfiehlt sich, die Durchführungen der shown. It is recommended that the bushings of the
Verstärkungsrohre 5 durch den Hauptquerträger 7 mit Hülsen 10 (nicht dargestellt) auszustatten. Gegenständliches Reinforcing tubes 5 by the main cross member 7 with sleeves 10 (not shown) equip. materic
Ausführungsbeispiel zeigt das Prinzip der Krafteinleitung aus dem Kopfstück 8, in konkreten Ausformungen ist auf die maximale Stützweite der Verstärkungsrohre 5 zu achten um ein Ausknicken der Verstärkungsrohre 5 zu verhindern. Dabei sind gegebenenfalls zusätzliche Stützstellen (Querträger) Embodiment shows the principle of the introduction of force from the head piece 8, in concrete formations is to pay attention to the maximum span of the reinforcing tubes 5 to prevent buckling of the reinforcing tubes 5.
