Abstract

A car unit, in particular for goods transport, consists of at least two car elements (1, 1') which are continuously connected to one another using buffers (2) and draw gear (3). A connecting linkage (4) which contains a plurality of joints (4a) with horizontal axis of rotation is coupled to the draw gear (3), by means of which connecting linkage (4) the car elements (1, 1') can be coupled to one another without play in the drawing direction and preferably with a slight pretensioning of the buffers (2). The connecting linkage (4) has inside at least one of its joints (4a) an elongate hole (4b) which is open in the pushing direction and is inclined at an angle with respect to the horizontal plane running through the centre of the associated coupling bolt (4c) in such a way that the connecting linkage (4) forcibly bends out downwards when buffer impacts occur. As a result, the connecting linkage (4) and the draw gear (3) are reliably protected against overloading. <IMAGE>

Description

Die Erfindung betrifft eine Wageneinheit, insbesondere für den Gütertransport, bestehend aus wenigstens zwei unter Einsatz von Puffern und Zugeinrichtungen ständig miteinander verbundenen Wagenelementen, wobei an den Zugeinrichtungen ein mehrere Gelenke mit horizontaler Drehachse enthaltendes Verbindungsgestänge angelenkt ist, durch das die Wagenelemente in Zugrichtung spielfrei und vorzugsweise unter einer geringen Vorspannung der Puffer miteinander kuppelbar sind.The invention relates to a carriage unit, in particular for the transportation of goods, consisting of at least two carriage elements which are permanently connected to one another using buffers and traction devices, wherein a connecting linkage containing a plurality of joints with a horizontal axis of rotation is articulated on the traction devices, by means of which the carriage elements are free of play and preferably in the pulling direction can be coupled to one another with a slight preload.

Eine Wageneinheit mit den vorgenannten Merkmalen ist durch UIC-Kodex 572 VE, 1. Ausgabe vom 01.01.1990, speziell Seite 17 bekannt. Die Wagenelemente sind unter Einsatz von Puffern und Zugeinrichtungen ständig miteinander gekuppelt, d. h. das dazu an den Zugeinrichtungen angelenkte Verbindungsgestänge soll kein Entkuppeln der Wagenelemente im laufenden Betrieb ermöglichen, wobei ein solches Gestänges durch den besagten UIC-Kodex nur umrißlich vorgegeben ist. Aufgrund einer Vielzahl von Wageneinheiten, die zumindest im westeuropäischen Eisenbahnnetz verkehren, gehört weiter ein Verbindungsgestänge zum Stand der Technik, das - entsprechend der grundsätzlichen Gestaltung nach UIC-Kodex - mehrere Gelenke mit jeweils horizontaler Drehachse enthält. Dieses Gestänge kann also wegen seiner Gelenke bei Pufferstößen nach unten ausknicken. Wie sich in der Praxis gezeigt hat, tritt das gewünschte Ausknicken bei besonders großen Stößen anfänglich nicht ein; das Verbindungsgestänge wirkt dann als starres Bauteil zwischen den Zugeinrichtungen der gekuppelten Wageneinheiten, so daß Schäden vor allem im Bereich der wagenseitigen Befestigung der Zugeinrichtungen nicht auszuschließen sind.A car unit with the above-mentioned features is known from UIC Code 572 VE, 1st edition from 01.01.1990, especially page 17. The car elements are constantly coupled to one another using buffers and traction devices, i.e. the connecting linkage articulated to the traction devices should not make it possible to uncouple the car elements during operation, such a linkage being only outlined by the UIC code. Due to the large number of wagon units that operate at least in the Western European rail network, a connecting linkage also belongs to the prior art, which - in accordance with the basic design according to the UIC Code - contains several joints, each with a horizontal axis of rotation. This linkage can buckle down due to its joints in the event of buffer impacts. As has been shown in practice, the desired buckling does not initially occur with particularly large impacts; the connecting linkage then acts as a rigid component between the traction devices of the coupled carriage units, so that damage, especially in the area of the carriage-side fastening of the traction devices, cannot be ruled out.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, das Verbindungsgestänge und die Zugeinrichtungen auf möglichst einfache Weise vor Überbeanspruchungen sicher zu schützen.The invention is therefore based on the object to protect the connecting linkage and the pulling devices in the simplest possible manner against overstressing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Verbindungsgestänge innerhalb zumindest eines seiner Gelenke ein in Druckrichtung offenes Langloch aufweist, das unter einem Winkel zu der durch die Mitte des zugehörigen Kuppelbolzens verlaufenden Horizontalebene derart geneigt ist, daß das Verbindungsgestänge bei auftretenden Pufferstößen zwangsläufig nach unten ausknickt.This object is achieved in that the connecting linkage has at least one of its joints an elongated hole which is open in the pressure direction and which is inclined at an angle to the horizontal plane running through the center of the associated coupling pin in such a way that the connecting linkage inevitably buckles downward when buffer bumps occur .

Nach einer bevorzugten Ausgestaltung der Erfindung ist das Langloch im Bereich des mit einer Kurzkupplung verbindbaren Endes eines Zwischenstückes angeordnet, das andererseits an der Zugeinrichtung gelenkig befestigt ist.According to a preferred embodiment of the invention, the elongated hole is arranged in the region of the end of an intermediate piece which can be connected to a close coupling, which on the other hand is articulated to the traction device.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

Gemäß Fig. 1 besteht die Wageneinheit aus zwei Wagenelementen 1, 1', von denen jedes einen Puffer 2 aufweist, der gegenüber dem jeweils anderen Wagenelement abgestützt ist. Weiter hat jedes Wagenelement 1, 1' eine Zugeinrichtung 3, die wie üblich im wesentlichen aus einer Feder 3a, einer gabelförmigen Zugstange 3b und einem wagenseitig angeschraubten Stützlager 3c gebildet ist.1, the carriage unit consists of two carriage elements 1, 1 ', each of which has a buffer 2 which is supported with respect to the other carriage element. Furthermore, each carriage element 1, 1 'has a pulling device 3 which, as usual, is essentially formed from a spring 3a, a fork-shaped pull rod 3b and a support bearing 3c screwed on the carriage side.

Zwischen den beiden Zugeinrichtungen 3 befindet sich ein Verbindungsgestänge 4, bestehend aus einer zentralen Gewindespindel 4e mit Vierkant, zwei bolzenartig gestalteten Kupplungsmuttern 4f, zwei Doppellaschen 4g, zwei Kuppelbolzen 4c sowie zwei Zwischenstücken 4d, die jeweils über einen Bolzen 4h an der gabelförmigen Zugstange 3b der Zugeinrichtung 3 geschlossen sind. Ein ungewolltes Lockern der Schraubenkupplung wird durch ein Sicherungsblech 4i verhindert, das den mittigen Vierkant der Gewindespindel 4e U-förmig umgreift.Between the two pulling devices 3 there is a connecting rod 4, consisting of a central one Threaded spindle 4e with square, two bolt-shaped coupling nuts 4f, two double brackets 4g, two coupling bolts 4c and two intermediate pieces 4d, which are each closed by a bolt 4h on the fork-shaped tie rod 3b of the pulling device 3. An unintentional loosening of the screw coupling is prevented by a locking plate 4i which engages around the central square of the threaded spindle 4e in a U-shape.

Wie aus der Zeichnung ersichtlich, hat das Verbindungsgestänge insgesamt vier Gelenke 4a mit horizontaler Drehachse, so daß es bei auftretenden Pufferstößen und damit verbundenen Druckkräften nach unten ausknicken kann. Um diese Knickbewegung zwangsläufig einzuleiten, ist in den beiden Zwischenstücken 4d jeweils ein in Druckrichtung offenes Langloch 4b angeordnet, wobei dieses Langloch 4b gemäß Fig. 3 unter einem Winkel zu der Horizontalebene geneigt ist, die durch die Mitte des zugehörigen Kuppelbolzens 4c verläuft. Bei Druckkräften bewegen sich also die beiden Kuppelbolzen 4c und damit die dortigen Enden der Doppellaschen 4g schräg nach oben, wodurch in den Doppellaschen 4g ein nach unten gerichteter Knickimpuls erzeugt wird. Um die korrekte Einbaulage "Langloch schräg nach oben" anzuzeigen, ist das Zwischenstück 4d mit einer sicht- und fühlbaren Markierung 5 versehen, hier einem Nocken.As can be seen from the drawing, the connecting linkage has a total of four joints 4a with a horizontal axis of rotation, so that it can buckle down in the event of buffer impacts and the associated pressure forces. In order to inevitably initiate this bending movement, an elongated hole 4b which is open in the pressure direction is arranged in each of the two intermediate pieces 4d, this elongated hole 4b according to FIG. 3 being inclined at an angle to the horizontal plane which runs through the center of the associated coupling pin 4c. In the case of compressive forces, the two coupling pins 4c and thus the ends of the double straps 4g there move obliquely upward, as a result of which a downward-directed buckling pulse is generated in the double straps 4g. In order to indicate the correct installation position "oblong hole obliquely upwards", the intermediate piece 4d is provided with a visible and tactile marking 5, here a cam.

Wegen der bei den Zwischenstücken 4d vorhandenen Wanddicke im Gelenkbereich, können die Langlöcher 4b dort auch nachträglich an bereits eingesetzten Wageneinheiten ausgeführt werden. Es versteht sich, daß alternativ eine entsprechende Anordnung von Langlöchern innerhalb anderer Gelenke 4a denkbar ist, beispielsweise in den Doppellaschen 4g.Because of the wall thickness in the joint area in the case of the intermediate pieces 4d, the elongated holes 4b can also be made there subsequently on carriage units which have already been used. It goes without saying that, alternatively, a corresponding arrangement of elongated holes within other joints 4a is conceivable, for example in the double brackets 4g.
