Abstract

The variable gauge running gear for rail vehicles has four wheels (1) and elements for the positioning and locking of the track width. The wheels and an associated wheel hub drive (2) are installed in a swinging arm (3), whereby the swinging arms are connected to horizontal bearing axles (4) on a chassis frame and for track change are movable on them in the transverse direction. The range of travel of the swinging arms in the transverse direction is limited on both sides by fixed stop (5), with the swinging arms being lockable in their two end positions.

Description

Die Erfindung betrifft ein Spurwechselfahrwerk für Schienenfahrzeuge mit vier Rädern und Elementen zum Positionieren und Verriegeln der Spurweite.The invention relates to a lane change chassis for rail vehicles with four Wheels and elements for positioning and locking the track width.

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, dessen Räder auf einfache Weise angetrieben und geführt sind. Außerdem sollen bei diesem Fahrwerk so weit wie möglich erprobte Baugruppen - wie Fahrwerkrahmen, Primärfederung, Sekundärfederung und, entsprechend den Anforderungen des Fahrzeugkastens, ein Wiegenträger mit Drehverbindung - realisierbar sein.The invention is based on the object, even for larger track width differences to create suitable undercarriage whose wheels on simple Way driven and guided. In addition, with this chassis as far as possible tested components - such as chassis frames, primary suspension, Secondary suspension and, according to the requirements of the vehicle body, a cradle with slewing ring - be realizable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Räder und ein zugehöriger Radnabenantrieb jeweils in einer Schwinge angeordnet sind, wobei die Schwingen an einem Fahrwerkrahmen an horizontalen Lagerachsen angelenkt und für den Spurwechsel auf diesen Lagerachsen in Querrichtung verschiebbar sind.This object is achieved in that the wheels and a associated wheel hub drive are each arranged in a rocker, wherein the wings on a chassis frame on horizontal bearing axles articulated and for the lane change on these bearing axles in the transverse direction are movable.

Am Querträger 7.2 befinden sich horizontale Lagerachsen 4 für Schwingen 3, die über Gleitlager an den Lagerachsen 4 gehalten sind. Die Schwingen 3 nehmen jeweils ein Rad 1 und einen zugehörigen Radnabenantrieb 2 auf. Jeder Radnabenantrieb 2 besteht aus einem Radnabenmotor und einem integrierten Planetengetriebe.The H-shaped, for example made of welded box profiles composite frame 7 of the chassis has longitudinal members 7.1 and a cross member 7.2. There are horizontal bearing axles on the cross member 7.2 4 for rockers 3, which are held on the bearing axles 4 via plain bearings are. The rockers 3 each take a wheel 1 and an associated one Wheel hub drive 2 on. Each wheel hub drive 2 consists of a wheel hub motor and an integrated planetary gear.

Zwischen den Schwingen 3 und den Längsträgern 7.1 des Fahrwerkrahmens 7 sind Primärfedern 9 angeordnet, z. B. Gummi-Metall-Federn. Die Primärfedern 9 übertragen die vertikalen Lasten zwischen den Schwingen 3 und dem Fahrwerkrahmen 7. Die Führung der Schwingen 3 in Längs- und Querrichtung erfolgt über die Lagerachsen 4. Der in Fig. 1 angedeutete Fahrzeugkasten 8 wird über Sekundärfedern 11 abgestützt, die zwischen dem Querträger 7.2 des Fahrwerkrahmens 7 und einem Wiegenträger 10 angeordnet sind. Als Sekundärfedern 11 eignen sich insbesondere hydropneumatische Federn; eine Verwendung von Stahlfedern ist ebenfalls möglich.Between the wings 3 and the side members 7.1 of the chassis frame 7 primary springs 9 are arranged, for. B. rubber-metal springs. The primary springs 9 transfer the vertical loads between the wings 3 and the Chassis frame 7. The guide of the rocker 3 in the longitudinal and transverse directions takes place via the bearing axles 4. The vehicle body 8 indicated in FIG. 1 is supported by secondary springs 11 which between the cross member 7.2 of the chassis frame 7 and a cradle 10 are arranged. As Secondary springs 11 are particularly suitable for hydropneumatic springs; the use of steel springs is also possible.

Für das Fahrwerk sind Scheibenbremsen mit hydraulischer Bremszangeneinheit 6.1 vorgesehen. Die Bremsscheibe 6.2 ist direkt am Radnabenantrieb 2 angeflanscht. Die Bremszangeneinheit 6.1 ist an der Schwinge 3 angebracht, so daß keine Relativbewegungen zwischen Bremszangeneinheit 6.1 und Bremsscheibe 6.2 auftreten. Die Schwingen 3 können außerdem jeweils eine Magnetschienenbremse tragen.Disc brakes with a hydraulic brake caliper unit are used for the chassis 6.1 provided. The brake disc 6.2 is directly on the wheel hub drive 2 flanged. The brake caliper unit 6.1 is attached to the rocker 3, so that no relative movements between brake caliper unit 6.1 and Brake disc 6.2 occur. The wings 3 can also each one Wear the magnetic rail brake.

Bei dem Fahrwerk nach der Erfindung wird der Spurwechsel durch Querverschieben der Schwingen 3 auf den horizontalen Lagerachsen 4 realisiert, wobei die Querverschiebung der Schwingen 3 auf beiden Seiten durch je einen Festanschlag 5 begrenzt ist. Die Schwingen 3 werden in den beiden Endpositionen verriegelt. Bei einer Änderung der Spurweite von z. B. 1435 mm auf 1000 mm beträgt der Verschiebeweg jeder Schwinge 3 in Querrichtung 217,5 mm. Die Längsträger 7.1 des Fahrwerkrahmens 7 sind derart breit ausgeführt, daß sie die Primärfedern 9 in beiden Endlagen der Schwingen 3 um 217,5 mm versetzt aufnehmen können.In the undercarriage according to the invention, the lane change is shifted by transverse movement the rocker 3 realized on the horizontal bearing axes 4, wherein the transverse displacement of the rocker 3 on both sides by one Fixed stop 5 is limited. The wings 3 are in the two end positions locked. When changing the gauge of z. B. 1435 mm The displacement of each rocker arm 3 in the transverse direction is 1000 mm mm. The longitudinal members 7.1 of the chassis frame 7 are designed so wide that they have the primary springs 9 in both end positions of the rocker 3 by 217.5 mm can accommodate offset.

Bei der vorgenannten Spurweite von 1435 mm befinden sich die Schwingen 3 in der äußeren Endstellung und sind verriegelt. Beim Einfahren in eine ortsfeste Umspuranlage wird das Fahrwerk nach und nach abgesenkt, bis Gleitkufen am Fahrwerkrahmen 7 Kontakt zu den der Umspuranlage zugehörigen Schienen für Führung und Zentrierung haben. Die Schwingen 3 senken sich gegenüber dem Fahrwerkrahmen 7 weiter ab, bis sie mit einem Ausschwinganschlag an Gleitflächen des Fahrwerkrahmens 7 aufliegen. Die auf den Schwingen 3 befestigten Primärfedern 9 sind in diesem Zustand frei, entlastet und aus ihrer Führung im Fahrwerkrahmen 7 abgehoben.The rockers 3 are located at the aforementioned track width of 1435 mm in the outer end position and are locked. When entering a stationary The undercarriage system gradually lowers the chassis until skids on the chassis frame 7 contact to those belonging to the gauge system Have rails for guiding and centering. The wings 3 lower towards the chassis frame 7 until it reaches a swing-out stop rest on sliding surfaces of the chassis frame 7. The on the Swing 3 attached primary springs 9 are free in this state, relieved and lifted out of their guidance in the chassis frame 7.

Die Schwingen 3 werden dann durch eine mechanische Betätigung über Führungsschienen in der Umspuranlage und einen Hebelmechanismus in der Mitte des Fahrwerks entriegelt. Anschließend werden die Schwingen 3 durch einen Radlenker bis zum inneren Anschlag verschoben. In dieser Stellung werden die Schwingen 3 durch Betätigung des Hebelmechanismus über die Führungsschiene bei einer Spurweite von 1000 mm verriegelt.The rockers 3 are then mechanically actuated via guide rails in the gauge system and a lever mechanism in the Unlocked middle of the undercarriage. Then the wings 3 through moved a wheel handlebar to the inner stop. In this position the wings 3 by operating the lever mechanism on the Guide rail locked at a track width of 1000 mm.

Beim Ausfahren aus der Umspuranlage kommen die Räder 1 wieder in Kontakt mit den von unten ansteigenden Schienen, und die Schwingen 3 heben von den Gleitflächen des Fahrwerkrahmens 7 ab, werden nach oben gegen den Fahrwerkrahmen 7 gedrückt und tragen dann wieder die Fahrzeugmasse. Bei diesem Vorgang werden die Primärfedern 9 wieder in ihre jeweilige Führung im Fahrwerkrahmen 7 eingedrückt. Die Gleitschuhe heben von den Schienen für Führung und Zentrierung ab. Der Umspurvorgang ist abgeschlossen. Der Umspurvorgang von 1000 mm auf 1435 mm läuft in umgekehrter Reihenfolge ab. When exiting the gauge system, the wheels 1 come into contact again with the rails rising from below, and lift the rocker 3 from the sliding surfaces of the chassis frame 7, are up against pressed the chassis frame 7 and then carry the vehicle mass again. In this process, the primary springs 9 are again in their respective guidance pressed into the chassis frame 7. The sliding shoes lift from the Rails for guiding and centering. The rerouting process is complete. The gauging process from 1000 mm to 1435 mm runs in reverse Order.
