Abstract
Description
Die Erfindung betrifft ein angetriebenes Spurwechselfahrwerk für Schienenfahrzeuge mit vier Rädern und Elementen zum Positionieren und Verriegeln der Spurweite.The invention relates to a powered lane change undercarriage for rail vehicles with four wheels and elements for positioning and locking the track.
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.In track-adjustable chassis according to the well-known principle TALGO is the conventional wheel, consisting of two wheel discs, which are pressed onto a common shaft, divided into two individual wheels with separate wheel shafts, which are mounted on both sides. The single wheel, the wheel shaft and the two-sided wheel bearings including the bearing housing form a wheel unit. The function of the previous wheel set shaft assumes a frame, the so-called axle bridge, in which the two wheel units are mounted and positioned in the respective track to each other. The axial locking of the wheel units via fastening eyes on the wheel bearing housing and guided in the axle bridge bars that are pulled vertically when Umspuren and share the wheel units for axial displacement. During the Umspurvorganges the vehicle weight is supported on skids on the axle bridge on the Umspuranlage, 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 width 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 chassis with wheel units according to the TALGO principle, the distance between the inner wheel bearing and the outer wheel bearing depends on the difference between the gauges that the chassis is to travel on. Larger gauge differences, z. B. from 1000 mm to 1435 mm lead to large bearing distances and correspondingly long wheel shafts. Such long wheel shafts can adversely affect the vehicle boundaries, limit the available space and possibly also cause strength problems.
Die EP-A1-0 648 659 beschreibt ein nicht angetriebenes Spurwechselfahrwerk mit Radschwingen.EP-A1-0 648 659 describes a non-driven lane change running gear with wheel swing.
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 has for its object to provide a suitable even for larger differences in track girth, the wheels are driven and guided in a simple manner. In addition, in this chassis as far as possible proven assemblies - such as chassis frame, primary suspension, secondary suspension and, according to the requirements of the vehicle body, a cradle carrier with rotary joint - be feasible.
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 an associated wheel hub drive are each arranged in a rocker, the rockers are hinged to a chassis frame on horizontal bearing axes and for the lane change on these bearing axes in the transverse direction are displaced.

Der H-förmig ausgebildete und beispielsweise aus geschweißten Kastenprofilen zusammengesetzte Rahmen 7 des Fahrwerks hat Längsträger 7.1 und einen Querträger 7.2. 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 and assembled, for example, welded
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
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.For the chassis disc brakes are provided with hydraulic brake caliper unit 6.1. The brake disk 6.2 is flanged directly on the
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 chassis according to the invention, the lane change is realized by transverse displacement of the
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.In the aforementioned gauge of 1435 mm, the
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
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 extending from the Umspuranlage the wheels come back into contact with the rising of the rails from below, and the
