Die Erfindung betrifft einen schienengebundenen Güterwagen mit Einrichtung zur Abstützung und Führung eines Stoßbalkens im Untergestell des Güterwagens, insbesondere für Güterwagen, die zum Transport von stoßempfindlichen Ladegütern eingesetzt werden.The invention relates to a rail freight wagon with means for supporting and guiding a bumper in the undercarriage of the freight wagon, in particular for freight wagons, which are used for the transport of shock-sensitive cargo.

Ein Eisenbahngüterwagen mit einer derartigen Einrichtung ist aus der DE 15 30 165 B2 bekannt. Diese besteht aus einem Stoßbalken, der im Untergestell des Güterwagens angeordnet ist und waagerechte, aus dem Fahrbetrieb resultierende Zug- und Stoßkräfte aufnimmt. Der Stoßbalken ist gegenüber dem Untergestell, das die Gewichte des Wagenkastens und der Zuladung aufnimmt, unter Zwischenschaltung eines Langhubstoßverzehrers längsverschiebbar gelagert. Der Stoßbalken ist mit seiner Unterseite auf Stützglieder des Untergestells abgestützt, wobei der Stützbalken mit seitlichem Spiel und unter Einhaltung eines Zwischenraumes zwischen seiner Oberseite und der Oberseite des Untergestells derart gelagert ist, dass der Stoßbalken bei Biegebeanspruchung des Untergestells weitgehend unbeaufschlagt bleibt.A railway freight wagon with such a device is known from DE 15 30 165 B2. This consists of a shock bar, which is arranged in the undercarriage of the freight car and receives horizontal, resulting from the driving operation tensile and impact forces. The buffer beam is mounted longitudinally displaceable with respect to the undercarriage, which receives the weights of the car body and the payload with the interposition of a Langhubstossverzehrers. The buffer beam is supported with its underside on support members of the underframe, wherein the support bar is supported with lateral play and while maintaining a gap between its top and the top of the undercarriage that the shock bar remains largely unencumbered in bending load of the undercarriage.

Die beschriebene Ausführung des Stoßbalkens als offenes Kastenprofil und die Art und Weise der Abstützung des Stoßbalkens im Untergestell gewährleistet insbesondere bei langen Schienenfahrzeugen und der damit verbundenen großen Anzahl von notwendigen Stützgliedern die Rückstellung des Stoßbalkens in seine Normallage nicht mehr sicher.The described embodiment of the bumper as an open box section and the way the support of the bumper in the base guaranteed especially in long rail vehicles and the associated large number of necessary support members, the provision of the bumper in its normal position no longer safe.

In der DE 41 10 986 C1 ist eine Stütz- und Führeinrichtung zur Lagerung eines Stoßbalkens im Untergestell eines Schienenfahrzeuges beschrieben, bei dem der Stoßbalken aus einem Paar seitlicher Längsträger gebildet ist, die sich in Richtung der Längsachse des Schienenfahrzeuges erstrecken. Die voneinander beabstandeten Längsträger sind durch im Abstand angeordnete Querträger untereinander verbunden. Die Längsträger weisen seitliche, nach außen gerichtete Ausnehmungen auf, in die im Untergestell angeordnete Stütz- und Führungselemente hinein ragen. Die Stütz- und Führungselemente sind als Gleitlager oder Wälzlager ausgebildet, die bezüglich einer Querebene jeweils paarig angeordnet und jeweils in gleicher Bauart, entweder als Gleitlager oder als Wälzlager ausgeführt sind.In DE 41 10 986 C1 a supporting and guiding device for supporting a bumper in the base of a rail vehicle is described in which the buffer beam is formed from a pair of lateral side members extending in the direction of the longitudinal axis of the rail vehicle. The spaced apart longitudinal members are interconnected by spaced-apart cross members. The longitudinal members have lateral, outwardly directed recesses into which support and guide elements arranged in the substructure protrude. The support and guide elements are designed as plain bearings or roller bearings, which are arranged in pairs with respect to a transverse plane and are each designed in the same design, either as plain bearings or as rolling bearings.

Die hier beschrieben Stütz- und Führungseinrichtung ermöglicht auch bei langen Schienenfahrzeugen ein sicheres Zurückführen des Stoßbalkens. Allerdings weist die Einrichtung einen komplizierten Aufbau auf und die Einstellung der vorgesehenen Toleranzen zwischen Stoßbalken einerseits und Stütz- und Führungselement andererseits erfordert die Bereitstellung und Befestigung seiten- und höhenverstellbarer Lagerböcke im Untergestell.The support and guide device described here allows safe return of the bumper even with long rail vehicles. However, the device has a complicated structure and the setting of the provided tolerances between buffer beam on the one hand and supporting and guiding element on the other hand requires the provision and attachment side and height adjustable bearing blocks in the base.

Zur Vereinfachung der Darstellung der erfindungsgemäßen Lösung wird auf die Darstellung des Fahrgestells und die Aufbauten des Güterwagens sowie die Kopfenden des Stoßbalkens 2 verzichtet.To simplify the presentation of the solution according to the invention, the representation of the chassis and the superstructures of the freight car and the head ends of the impact bar 2 are dispensed with.

Das Untergestell 1 des Güterwagens wird durch zwei seitliche und beabstandete, in Güterwagenlängsrichtung verlaufende Langträger 3 gebildet, die miteinander durch eine Vielzahl von Querträgern 4 verbunden sind. Die Langträger 3 erfüllen im wesentlichen die Tragfunktion des Güterwagens. Auf den Querträgern 4 sind vier Trägerprofile 5 angeordnet, die den Fußboden 6 des Güterwagens aufnehmen. Der Fußboden 6 besteht vorzugsweise aus Sperrholz (Multiplexplatten) . Im vorliegenden Ausführungsbeispiel werden die Trägerprofile 5 aus U-Profilen gebildet, die sich in Längsrichtung des Güterwagens, parallel zu den Langträgern 3 erstrecken. Dabei werden die U-Profile so angeordnet, dass der eine Flansch auf dem Querträger 4 aufliegt und mit diesem verbunden wird und der gegenüberliegende Flansch den Fußboden 6 trägt.The undercarriage 1 of the freight wagon is formed by two lateral and spaced, running in the longitudinal direction of the wagon longitudinal beams 3, which are interconnected by a plurality of cross members 4. The longitudinal beams 3 essentially fulfill the supporting function of the freight wagon. On the crossbeams 4 four carrier profiles 5 are arranged, which receive the floor 6 of the freight car. The floor 6 is preferably made of plywood (multiplex panels). In the present embodiment, the carrier profiles 5 are formed from U-profiles, which extend in the longitudinal direction of the freight car, parallel to the longitudinal beams 3. The U-profiles are arranged so that the one flange rests on the cross member 4 and is connected thereto and the opposite flange carries the floor 6.

Der von den beiden inneren Trögerprofilen 5, die sich mit ihren offenen Seiten gegenüberstehen, der Oberkante des Querträgers 4 und der Unterseite des Fußbodens 6 eingeschlossene, sich über die gesamte Länge des Güterwagens erstreckende Raum dient der verschiebbaren Aufnahme des sich über die gleiche Länge erstreckenden Stoßbalkens 2. Der Stoßbalken 2 wird aus zwei parallel verlaufenden Doppel-T-Trägern 7 gebildet, die untereinander durch quer verlaufende Streben 8 beabstandet sind. Auf diese Weise gewährleisten Doppel-T-Träger 7 und Streben 8 einen kompakten Verbund des Stoßbalkens 2.Of the two inner Trögerprofilen 5, which face with their open sides, the upper edge of the cross member 4 and the underside of the floor 6 enclosed, extending over the entire length of the freight car space serves the slidably receiving the extending over the same length bumper 2. The buffer beam 2 is formed from two parallel double-T-beams 7, which are spaced apart by transverse struts 8. In this way, double T-beam 7 and struts 8 ensure a compact composite of the bumper 2.

Die Abstützung und Führung des Stoßbalkens 2 erfolgt über Klammern 9, die C-förmig ausgebildete Aussparungen 10 aufweisen. Die Klammern 9 werden paarweise an den Querträger 4 oder an Hilfsträgern in der Weise fixiert, dass sie mit ihren Aussparungen 10 in den Raum für die Aufnahme des Stoßbalkens 2 hineinragen. Dabei wird der nach Innen gerichtete Bereich des Untergurtes des Doppel-T-Trägers 7 von der Aussparung 10 aufgenommen. Die Anzahl und der Abstand der Klammern 9 in Wagenlängsrichtung richtet sich nach der Knicklänge des Stoßbalkens 2.The support and guidance of the bumper 2 via brackets 9, the C-shaped recesses 10 have. The brackets 9 are fixed in pairs to the cross member 4 or to auxiliary carriers in such a way that they protrude with their recesses 10 in the space for receiving the bumper 2. In this case, the inwardly directed region of the lower flange of the double-T-carrier 7 is received by the recess 10. The number and the distance of the brackets 9 in the vehicle longitudinal direction depends on the buckling length of the bumper 2.

Gemäß der Fig. 2 und 3 sind die Klammern 9 im Bereich der Aussparung 10 in besonderer Weise ausgebildet. Fig. 2 zeigt eine detaillierte Darstellung der als Stütz- und Führungselement ausgebildeten Klammer 9 mit Gleitstücken 11. Im Bereich der Aussparung 10 sind an allen Seiten Gleitstücke 11 angeordnet, die vorzugsweise mit entsprechend gegenüberliegenden Gleitstücken 12 am von der Klammer 9 beaufschlagten Bereich des Untergurtes des Doppel-T-Trägers 7 korrespondieren.According to FIGS. 2 and 3, the brackets 9 are formed in the region of the recess 10 in a special way. Fig. 2 shows a detailed illustration of the trained as a support and guide element bracket 9 with sliders 11. In the region of the recess 10 sliders 11 are arranged on all sides, the preferably correspond with corresponding opposing sliders 12 on acted upon by the bracket 9 area of the lower flange of the double-T-beam 7.

Fig. 3 zeigt eine detaillierte Darstellung der als Stütz- und Führungselement ausgebildeten Klammer 9 mit Rollen 13. Diese Lösung kann ggf. zweckmäßig sein, um die Reibung zwischen Stoßbalken 2 und Abstützung am Untergestell 1 zu vermindern und kann auch zusammen mit Stütz- und Führungselementen mit Gleitstücken 11, 12 kombiniert werden. Bei dieser Klammer 9 sind im Bereich der Aussparung 10 Rollen 13 derart angeordnet, dass sie der Oberseite, der Unterseite und der Stirnseite des von der Aussparung 10 aufgenommenen Bereiches des Untergurtes des Doppel-T-Trägers 7 gegenüberstehen.FIG. 3 shows a detailed illustration of the bracket 9 with rollers 13 designed as a support and guide element. This solution may be expedient if necessary to reduce the friction between the buffer beam 2 and the support on the underframe 1 and can also be combined with support and guide elements can be combined with sliders 11, 12. In this clamp 9, rollers 13 are arranged in the region of the recess 10 such that they face the upper side, the lower side and the front side of the region of the lower flange of the double-T carrier 7 received by the recess 10.

In den Figuren 4 und 5 ist eine besonders wirtschaftliche und fertigungstechnisch vorteilhafte Ausführungsform der Gleitstücke 11 dargestellt. Stoßbalkenseitige Gleitstücke 12 können entfallen. Es ist lediglich ein Gleitstück 11 auf der Seite der Klammer 9 vorgesehen. Das Gleitstück 11 ist aus zwei zusammengefügten Gleitstückteilen 14 (Formstücke aus Kunststoff) gebildet, die beidseitig die Klammer 9 im Bereich der Aussparung 10 einfassen, die Aussparung 10 durchdringen und somit eine kompakte Baugruppe "Gleitstück" darstellt. Es entföllt damit das aufwändige Justieren und Fixieren von einzelnen Gleitstücken 11 und 12 in Längs- und Ouerrichtung an der Klammer 9 und dem Doppel-T-Träger 7. Die Gleistückteile 14 sind mittels lösbarer Befestigungsmittel 15, insbesondere mittels Schraub-/Mutterverbindung miteinander und an der Klammer 9 befestigt, womit auch ein leichter Austausch bewerkstelligt werden kann. Weiterhin weisen die Gleitstücke 14 eine C-förmig Ausnehmung auf, in die der Untergurt des Doppel-T-Trägers 7 des Stoßbalkens 2 geführt ist. Vorzugsweise bestehen die Gleitstückteile 14 aus dem Werkstoff Polyamid. Das Fixieren der Gleitstückteile 14 an der Klammer 9 kann vor dem Befestigen der Klammer 9 am Querträger 4 bzw. am Hilfsträger erfolgen.In Figures 4 and 5, a particularly economical and manufacturing technology advantageous embodiment of the sliders 11 is shown. Bumper-side sliders 12 can be omitted. It is merely a slider 11 on the side of the bracket 9 is provided. The slider 11 is formed of two joined Gleitstückteilen 14 (fittings made of plastic), the clamp 9 on both sides in the region of the recess 10, the recess 10 penetrate and thus represents a compact assembly "slider". It thus freed up the complex adjustment and fixing of individual sliders 11 and 12 in the longitudinal and Ouerrichtung on the bracket 9 and the double-T-carrier 7. The Gleistückteile 14 are by means of releasable fastening means 15, in particular by means of screw / nut connection with each other and the bracket 9 attached, whereby also a simple replacement can be accomplished. Furthermore, the sliders 14 have a C-shaped recess into which the lower flange of the double-T-beam 7 of the bumper 2 is guided. Preferably, the Gleitstückteile 14 made of the material polyamide. The fixing of the Gleitstückteile 14 on the bracket 9 can be done before attaching the bracket 9 on the cross member 4 and the subcarrier.

Die mit Gleitstücken 11, Gleitstückteilen 14 bzw. mit Rollen 13 ausgestatteten Klammern 9 dienen der leichteren und verschleißarmen Führung des Stoßbalkens 2 im Untergestell 1 des Güterwagens. Bei der Beaufschlagung des Stoßbalkens 2 z.B. im Rangierbetrieb des Güterwagens durch den Aufprall des Stoßbalkens eines benachbarten auflaufenden Güterwagens, erfährt der Stoßbalken 2 eine Längsverschiebung im Untergestell 1, die durch eine nicht dargestellte und nicht näher beschriebene Energieverzehr- und Rückstelleinrichtung aus dem Stand der Technik gedämpft wird. Die Rückführung des Stoßbalkens 2 in seine Normallage wird durch die erfindungsgemäßen Klammern 9 unterstützt.The equipped with sliders 11, Gleitstückteilen 14 or with rollers 13 brackets 9 are used for easier and low-wear guidance of the bumper 2 in the undercarriage 1 of the freight car. Upon application of the bumper 2, e.g. in the shunting of the freight car by the impact of the bumper of an adjacent oncoming freight car, the buffer beam 2 undergoes a longitudinal displacement in the undercarriage 1, which is attenuated by a not shown and unspecified energy dissipation and restoring device from the prior art. The return of the bumper 2 in its normal position is supported by the brackets 9 according to the invention.

Der besondere Vorteil der erfindungsgemäßen Einrichtung zur Abstützung und Führung des Stoßbalkens 2 besteht für alle Lösungsbeispiele darin, dass die Klammern 9 vor dem Fixieren an dem Querträger 4 durch Verschweißen oder Verschrauben auf einfache Weise zu dem in seiner Normallage ausgerichteten Stoßbalken 2 positioniert werden können. Die Klammern 9 sind sowohl in vertikaler als auch in horizontaler Richtung einstellbar. Winkelfehler des Stoßbalkenuntergurtes können bei der Positionierung ousgeglichen werden.The particular advantage of the device according to the invention for supporting and guiding the bumper 2 for all examples of solutions is that the clamps 9 can be positioned in a simple manner to the bumper 2 aligned in its normal position prior to fixing to the cross member 4 by welding or screwing. The brackets 9 are adjustable both in the vertical and in the horizontal direction. Angular errors of the bottom edge of the buffer beam can be compensated during positioning.
