Description

Die Erfindung betrifft ein Schienenfahrzeug, insbesondere einen langen Güterwagen, mit zwei Radsätzen und mit einem zumindest aus zwei Kopfträgern, nachgeordneten Querträgern und zwei äußeren Langträgern gebildeten Untergestell.The invention relates to a rail vehicle, in particular a long freight wagon, with two wheelsets and with an underframe formed at least from two head girders, subordinate cross girders and two outer long girders.

Gemäß einschlägigen eisenbahntechnischen Vorschriften (z.B. der UIC) müssen derartige Schienenfahrzeuge im Hinblick auf ihre Sicherheit gegen Entgleisen eine auf die Radaufstandspunkte als Meßbasis bezogene, ausreichende Verwindungsfähigkeit aufweisen, die unter entsprechender Auslegung der Radsatzfederung erbringbar ist. Um diese Fahrzeuge auch bei größeren Längsdruckkräften (Pufferstößen) entgleisungssicher betreiben zu können, wird für den dabei beanspruchten Fahrzeugaufbau eine von der Fahrzeugeigenmasse und der Längserstreckung der Fahrzeug- überhänge abhängige Verwindungssteifigkeit gefordert. Bei geringerer Eigenmasse und längeren Überhängen (z.B. jeweils 3 m bei einem Fahrzeug mit einer Länge über Puffer von 15 m und mit heute maximalem Radsatzabstand von 9 m) ist.die verlangte höhere Verwindungssteifigkeit vor allem dann schwieriger erzielbar, wenn für eine entsprechend steifere Gestaltung im wesentlichen nur das Untergestell heranziehbar ist.In accordance with the relevant railway regulations (e.g. the UIC), such rail vehicles must have sufficient torsional strength with regard to their safety against derailment, based on the wheel contact points as a measuring basis, which can be achieved with the appropriate design of the wheel set suspension. In order to be able to operate these vehicles safely against derailment even with greater longitudinal compressive forces (buffer surges), a torsional stiffness that is dependent on the vehicle's own mass and the longitudinal extent of the vehicle overhangs is required for the vehicle body that is claimed. With a lower dead weight and longer overhangs (e.g. 3 m in each case for a vehicle with a length over buffers of 15 m and with a maximum wheelbase spacing of 9 m today), the higher torsional rigidity required is more difficult to achieve, especially if the design is correspondingly more rigid essentially only the base frame can be used.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, ein Schienenfahrzeug der gattungsgemäßen Art an seinem Untergestell im Sinne einer geforderten Verwindungssteifigkeit zu gestalten, wobei diese Gestaltung auf möglichst einfache und vom Gewicht her günstige Weise erfolgen soll.The invention is accordingly based on the object of designing a rail vehicle of the generic type on its base frame in the sense of a required torsional rigidity, this design being intended to be carried out in the simplest possible manner and with a weight which is favorable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die äußeren Langträger durch oberhalb und unterhalb mit größtmöglichem Abstand zur Längsschwerlinie des Untergestells jeweils diagonal angeordnete Zugglieder miteinander verbunden sind.This object is achieved in that the outer long beams are connected by diagonally arranged tension members above and below with the greatest possible distance from the longitudinal center of gravity of the base frame.

Der Gegenstand nach der Erfindung zeichnet sich durch seine besonders einfache, kostengünstig herstellbare Gestaltung und die damit erzielte vorschriftengerechte Verwindungssteifigkeit aus, wobei die dazu angeordneten Zugglieder in vorteilhafter Weise die Fahrzeugeigenmasse praktisch nicht vergrößern, wodurch eine optimal hohe Ladungsmasse ermöglicht ist.The object according to the invention is characterized by its particularly simple, inexpensive to produce design and the torsional rigidity achieved in accordance with the regulations, the tension members arranged for this advantageously advantageously practically not increasing the vehicle's own mass, which enables an optimally high load mass.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Ein Aus£ührungsbeispiel der Erfindung ist in der Zeichnung prinzipartig dargestellt und wird im folgenden näher beschrieben. Es zeigen

  • Fig. 1 ein Schienenfahrzeug im Bereich seines Untergestells im Längsschnitt,
  • Fig. 2 die Draufsicht zu Fig. l,
  • Fig. 3 die Ansicht in Pfeilrichtung Z zu Fig. 1
  • Fig. 4 die Einzelheit Y aus Fig. 3, im vergrößerten Maßstab.
An exemplary embodiment of the invention is shown in principle in the drawing and is described in more detail below. Show it
  • 1 is a rail vehicle in the region of its base in longitudinal section,
  • 2 shows the top view of FIG. 1,
  • 3 shows the view in the direction of arrow Z to FIG. 1
  • Fig. 4 shows the detail Y of Fig. 3, on an enlarged scale.

Gemäß den Fig. 1 bis 3 hat das Fahrzeug-Untergestell in seinem Grundaufbau zwei Kopfträger 1 (siehe Fig. l) mit daran angebrachten, nicht dargestellten Seitenpuffern, den Kopfträgern 1 nachgeordnete Querträger 2, zwei äußere Langträger 3 und hier weggelassene mittlere Langträger. Die mit Achshaltern 7 für Radsätze 8 versehenen äußeren Langträger 3 sind im Ausführungsbeispiel nach Art eines Fischbauchträgers (siehe Fig. 1) ausgelegt.According to FIGS. 1 to 3, the basic structure of the vehicle undercarriage has two head supports 1 (see FIG. 1) with side buffers (not shown) attached to it, cross members 2 arranged downstream of the head supports 1, two outer long supports 3 and middle long supports omitted here. The outer long beams 3 provided with axle holders 7 for wheel sets 8 are designed in the exemplary embodiment in the manner of a fish belly beam (see FIG. 1).

Weiter nach Fig. 1 bis 3 sind die äußeren Langträger 3 zum Erzielen einer höheren Verwindungssteifigkeit durch obere und untere Zugglieder 4a bzw. 4b miteinander verbunden, die oberhalb und unterhalb mit größtmöglichem Abstand zur Längsschwerlinie des Untergestelles jeweils diagonal angeordnet sind. In Längsrichtung des Untergestelles erstrecken sich die oberen und unteren Zugglieder 4a bzw. 4b über einen durch ein Paar von Querträgern 2' begrenzten Längsabschnitt, wobei diese Querträger 2' mit den Langträgern 3 im Bereich ihres Überganges von konstanter Trägerhöhe in steigende Trägerhöhe verbunden sind. Die im Hinblick auf den größtmöglichen Abstand von der Längsschwerlinie aus Flachprofilen be- .· stehenden oberen Zugglieder 4a sind oberhalb der Querträger 2 in Horizontallage angeordnet und an den äußeren Langträgern 3 in deren Knotenpunktbereich mit den beiden Querträgern 2' durch Schweißen angeschlossen.1 to 3, the outer long beams 3 are connected to each other to achieve a higher torsional rigidity by upper and lower tension members 4a and 4b, which are arranged diagonally above and below with the greatest possible distance to the longitudinal center of gravity of the base frame. In the longitudinal direction of the underframe, the upper and lower tension members 4a and 4b extend over a longitudinal section delimited by a pair of cross beams 2 ', these cross beams 2' being connected to the long beams 3 in the region of their transition from constant beam height to increasing beam height. With regard to the greatest possible Ab stood from the longitudinal center of gravity consisting of flat profiles. · Upper tension members 4a are arranged horizontally above the cross members 2 and connected to the outer long members 3 in their node area with the two cross members 2 'by welding.

Wie aus Fig. 3 ersichtlich, bestehen die unteren Zugglieder 4b aus drei sich diagonal kreuzenden Paaren, von denen das mittlere Paar innerhalb des Längsabschnittes der gleichbleibend vergrößerten Höhe der Langträger 3 angeordnet ist. Die beiden äußeren Paare der unteren Zugglieder 4b liegen innerhalb derjenigen Langträger-Übergangsabschnitte, die durch die Enden des vorgenannten Längsabschnittes und die Bereiche des Überganges von konstanter in steigende Trägerhöhe (Querträger 2') begrenzt sind.As can be seen from FIG. 3, the lower tension members 4b consist of three diagonally crossing pairs, of which the middle pair is arranged within the longitudinal section of the constantly increased height of the long beams 3. The two outer pairs of the lower tension members 4b lie within those long beam transition sections which are delimited by the ends of the aforementioned longitudinal section and the areas of the transition from constant to increasing beam height (cross beam 2 ').

In den Fig. 1, 3 und 4 gezeigte, querangeordnete Rohre 5, die als Distanzhalter zwischen den Angriffspunkten des mittleren Paares und der beiden äußeren Paare der unteren Zugglieder 4b an den Langträgern 3 vorgesehen sind, verhindern Verformungen der Langträger 3, wobei diese Rohre 5 auch der Verwindungssteifigkeit dienlich sind. Im übrigen weisen die Langträger 3 im Bereich der vorgenannten Angriffspunkte angeordnete Stegbleche 6 als Aussteifungen auf.1, 3 and 4, transversely arranged tubes 5, which are provided as spacers between the points of engagement of the middle pair and the two outer pairs of the lower tension members 4b on the long beams 3, prevent deformations of the long beams 3, these pipes 5 are also conducive to torsional rigidity. In addition, the long girders 3 have web plates 6 arranged in the area of the aforementioned points of attack as stiffeners.

Nach Fig. 4 sind die aus einem Rundprofil bestehenden unteren Zugglieder 4b durch Spannschlösser 4c in ihrer Länge einstellbar ausgebildet. Eine entsprechende Einstellbarkeit könnte auch bei den oberen Zuggliedern 4a vorliegen. Durch die Längeneinstellbarkeit sind ein strammer Sitz und sogar eine günstige Vorspannung der Zugglieder 4b einfach erzielbar. Für eine gute Zugänglichkeit des Untergestelles von unten sind die unteren Zugglieder 4b über Bolzen 4d lösbar mit den äußeren Langträgern 3 verbunden.According to FIG. 4, the lower tension members 4b, which consist of a round profile, are adjustable in their length by turnbuckles 4c. A corresponding adjustability could also be the case with the upper tension members 4a are available. Due to the length adjustment, a tight fit and even a favorable pretensioning of the tension members 4b can easily be achieved. For good accessibility of the underframe from below, the lower tension members 4b are detachably connected to the outer long beams 3 via bolts 4d.

Die unteren Zugglieder 4b sind in ihrem jeweiligen Kreuzungspunkt durch eine Grundplatte 9, an denen übliche, die Zugglieder 4b umgreifende Schellen befestigt sind, gehaltert.The lower tension members 4b are held in their respective crossing point by a base plate 9, to which conventional clamps, which surround the tension members 4b, are fastened.
