The elements for the positioning and locking of the track width are installed on the front (3.1) and rear (3.2) supports of the frame serving as a wheel bridge.

Description

Die Erfindung betrifft ein Spurwechselfahrwerk für Schienenfahrzeuge mit Radeinheiten, Achsbrücken und Elementen zum Positionieren und Verriegeln der Spurweite.The invention relates to a lane change undercarriage for rail vehicles Wheel units, axle bridges and elements for positioning and locking the gauge.

Bei spurweitenverstellbaren Fahrwerken nach dem bekannten Prinzip TALGO ist der herkömmliche Radsatz, bestehend aus zwei Radscheiben, die auf einer gemeinsamen Welle aufgepreßt sind, aufgeteilt in zwei Einzelräder mit separaten Radwellen, die beidseitig gelagert werden. Das Einzelrad, die Radwelle und die beidseitigen Radlagerungen einschließlich der Lagergehäuse bilden eine Radeinheit. Die Funktion der früheren Radsatzwelle übernimmt ein Rahmen, die sogenannte Achsbrücke, in der die beiden Radeinheiten gelagert sind und in der jeweiligen Spurweite zueinander positioniert werden. Die axiale Verriegelung der Radeinheiten erfolgt über Befestigungsaugen am Radlagergehäuse und in der Achsbrücke geführte Riegel, die beim Umspuren vertikal gezogen werden und die Radeinheiten zur axialen Verschiebung freigeben. Während des Umspurvorganges stützt sich das Fahrzeuggewicht über Gleitkufen an der Achsbrücke auf die Umspuranlage ab, so daß die Radeinheiten entlastet sind und mit geringem Kraftaufwand verschoben werden können. Die Breite des Riegels und des Befestigungsauges bestimmen den Verschiebeweg und damit die Spurweitenänderung.With track-adjustable undercarriages based on the well-known TALGO principle is the conventional wheel set, consisting of two wheel disks on one common shaft are pressed, divided into two individual wheels with separate wheel shafts that are supported on both sides. The single wheel that Wheel shaft and the double-sided wheel bearings including the bearing housing form a wheel unit. The function of the previous wheelset shaft takes over a frame, the so-called axle bridge, in which the two wheel units are mounted and are positioned in relation to each other in the respective track gauge. The The wheel units are axially locked using fastening eyes on Wheel bearing housing and bolts guided in the axle bridge, which are used for re-gauging be pulled vertically and release the wheel units for axial displacement. The vehicle weight is supported during the re-gauging process Skids on the axle bridge onto the gauge system, so that the wheel units are relieved and can be moved with little effort. The width of the bolt and the fastening eye determine the displacement and thus the track gauge change.

Bei Fahrwerken mit Radeinheiten nach dem TALGO-Prinzip ist der Abstand zwischen der innenliegenden Radlagerung und der außenliegenden Radlagerung von der Differenz der Spurweiten abhängig, die das Fahrwerk befahren soll. Größere Spurweitenunterschiede, z. B. von 1000 mm auf 1435 mm führen zu großen Lagerabständen und entsprechend langen Radwellen. Solche langen Radwellen können nachteilig die Fahrzeugumgrenzungen verletzen, den verfügbaren Bauraum einschränken und möglicherweise auch Festigkeitsprobleme bereiten. For undercarriages with wheel units based on the TALGO principle, the distance is between the inner wheel bearing and the outer wheel bearing depends on the difference in the track widths that drive on the chassis should. Larger track gauge differences, e.g. B. from 1000 mm to 1435 mm too large bearing distances and correspondingly long wheel shafts. Such long wheel shafts can adversely violate vehicle boundaries, limit the available space and possibly also strength problems prepare.

Der Erfindung liegt die Aufgabe zugrunde, ein auch für größere Spurweitenunterschiede geeignetes Fahrwerk zu schaffen, bei dem der Lagerabstand möglichst gering gehalten ist und möglichst kurze Radwellen eingesetzt werden.The invention is based on the object, even for larger track width differences to create a suitable chassis in which the bearing distance is kept as low as possible and the shortest possible wheel shafts are used.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Radeinheiten jeweils in einem eigenen, als Radbrücke dienenden Rahmen gelagert sind, der die Radscheibe umschließt, wobei die in Querrichtung des Fahrwerks gegenüberliegenden Radbrücken gegenüber der Achsbrücke verschiebbar geführt sind.This object is achieved in that the wheel units are each stored in their own frame serving as a wheel bridge, which surrounds the wheel disc, the opposite in the transverse direction of the chassis Wheel bridges slidably guided in relation to the axle bridge are.

Der Vorteil dieser Lösung liegt insbesondere in der durch die Radbrücke ermöglichten schmalen Bauweise der Radeinheit, bei der eine kurze Radwelle verwendet wird und dementsprechend der Lagerabstand gering gehalten ist. Dadurch können die Fahrzeugumgrenzung eingehalten und der vor allem für Antriebskomponenten notwendige Bauraum freigehalten werden. Weiter günstig sind die Radbrücken unabhängig von der Spurweite ausgebildet.The advantage of this solution is in particular that made possible by the wheel bridge narrow design of the wheel unit, in which a short wheel shaft is used and accordingly the bearing distance is kept small. This allows the vehicle boundary to be complied with and, above all, for Drive components necessary space are kept free. Further The wheel bridges are inexpensive regardless of the track width.

Nach einer Ausgestaltung der Erfindung sind die Elemente zur Positionierung und Verriegelung der Spurweite am vorderen Querträger und am hinteren Querträger des als Radbrücke dienenden Rahmens angeordnet. Die Verriegelungselemente befinden sich also nicht mehr, wie bei dem System TALGO, an den Radlagern. Es ist zu berücksichtigen, daß die von der ortsfesten Umspuranlage betätigten Bauelemente außerhalb des Bereiches liegen, der von der Radscheibe beim Umspuren überstrichenen wird.According to one embodiment of the invention, the elements are for positioning and locking the track width on the front crossmember and on the rear Cross member of the frame serving as a wheel bridge arranged. The locking elements are no longer like in the TALGO system, on the wheel bearings. It should be borne in mind that that of the fixed gauge system actuated components are outside the range of the wheel disc is swept over during re-gauging.

Bei dem gezeigten Fahrwerk sind die Radeinheiten 1 jeweils in einem eigenen, als Radbrücke 3 dienenden Rahmen gelagert. Jede dieser Radbrücken 3 umschließt eine Radscheibe. Die in Querrichtung des Fahrwerks gegenüberliegenden Radbrücken 3 sind gegenüber der jeweiligen Achsbrücke 2 verstellbar geführt, um dadurch einen Spurwechsel vornehmen zu können. Am vorderen Querträger 3.1 und am hinteren Querträger 3.2 des als Radbrücke 3 dienenden Rahmens sind Elemente zum Positionieren und Verriegeln der Spurweite angeordnet. Durch diese Elemente werden die Radbrücken 3 formschlüssig in der Achsbrücke 2 positioniert und gegen unbeabsichtigte Verschiebung mechanisch verriegelt. Die Positionier- und Verriegelungsmechanik ist so angeordnet, daß die Radbrücke 3 auch in Längsrichtung in der Achsbrücke 2 geführt ist.In the chassis shown, the wheel units 1 are each in their own, served as a wheel bridge 3 serving frame. Each of these wheel bridges 3 encloses a wheel disc. The opposite in the transverse direction of the chassis Wheel bridges 3 are adjustable relative to the respective axle bridge 2 guided in order to be able to change lanes. At the front cross member 3.1 and at the rear cross member 3.2 of the wheel bridge 3rd serving frames are elements for positioning and locking the Track width arranged. These elements make the wheel bridges 3 form-fitting positioned in the axle bridge 2 and against unintentional displacement mechanically locked. The positioning and locking mechanism is arranged so that the wheel bridge 3 also in the longitudinal direction in the axle bridge 2 is performed.

Der Rahmen des dargestellten Fahrwerks besteht im wesentlichen aus einem unteren Querträger 4 und seitlichen Längsträgern 5. Zwischen den Längsträgern 5 und den Achsbrücken 2 befinden sich Primärfedern 6. Diese Primärfedern 6 (bzw. Lenker) dienen auch der Führung der Achsbrücke 2 gegenüber dem Rahmen des Fahrwerks. Auf dem Querträger 4 ist ein Wiegenträger 7 über Sekundärfedern 8 abgestützt.The frame of the chassis shown consists essentially of a lower cross member 4 and lateral side members 5. Between the side members 5 and the axle bridges 2 are primary springs 6. These primary springs 6 (or handlebars) also serve to guide the axle bridge 2 opposite the frame of the chassis. On the cross member 4 is a cradle 7 supported on secondary springs 8.

Das Fahrwerk hat im Ausführungsbeispiel zwei Antriebsmotore 9, die jeweils durch eine Gelenkwelle 10 mit einem Radgetriebe 11 gekoppelt sind. Die Radgetriebe 11 sind über Antriebswellen 12 mit den Radeinheiten 1 verbunden. Im übrigen ist das Fahrwerk mit Wellenbremseinheiten 13 ausgerüstet, deren Bremsscheiben auf einer Verlängerung der Motorwellen der Antriebsmotore 9 angeordnet sind.In the exemplary embodiment, the chassis has two drive motors 9, each are coupled to a wheel transmission 11 by a propeller shaft 10. The Wheel gears 11 are connected to the wheel units 1 via drive shafts 12. Otherwise, the undercarriage is equipped with shaft brake units 13, their brake discs on an extension of the motor shafts of the drive motors 9 are arranged.

Besondere Vorteile der erfindungsgemäßen Lösung liegen in der schmalen Bauweise der Radeinheiten 1 sowie darin, daß die Radeinheiten 1 mit den zugehörigen Radbrücken 3 nach dem Baukastenprinzip spurweitenunabhängig ausgebildet sind und somit für verschiedenste Spurweitendifferenzen verwendet werden können. Particular advantages of the solution according to the invention lie in the narrow Construction of the wheel units 1 and in that the wheel units 1 with the Associated wheel bridges 3 independent of track width according to the modular principle are trained and thus used for a wide variety of track width differences can be.
