Description

Die Erfindung betrifft ein Laufwerk für Standseil-Pendelbahnen nach dem Oberbegriff des Anspruchs 1 sowie einen starren Radsatz für ein solches Laufwerk nach dem Oberbegriff des Patentanspruchs 3.The invention relates to a drive for funicular aerial tramways according to the preamble of Claim 1 and a rigid wheel set for such a drive according to the preamble of Claim 3.

Die Erfindung bezieht sich auf Standseilbahnen mit Pendelbetrieb, die eingleisig mit automatischer Abt'scher Ausweiche ausgeführt sind.The invention relates to funiculars with shuttle operation, the single track with automatic Dodge diverters are implemented.

Bisherige Ausführungen von Standseilbahn-Laufwerken als Einzelachs-Radsätze bei zweiachsigen Wagen oder als mehrachsige Drehgestelle weisen zwei ungleich gestaltete Räder stets gleich großen Durchmessers auf, wobei ein Rad zwei Spurkränze, das andere hingegen keinen Spurkranz aufweist. Die Laufflächen beider Räder des Radsatzes sind zylindrisch. Nachteilig an dieser Ausbildung der Radsätze ist eine schlechte Laufeigenschaft auch auf geraden Streckenabschnitten, da das Zugseil bei Pendelbahnen zwangsläufig exzentrisch zum Schwerpunkt des symmetrisch gebauten Wagens angreifen muß, weil auf der Strecke zwei Seilstränge nebeneinander geführt werden. Diese Exzentrizität hat zur Folge, daß jeweils ein Spurkranz während der Fahrt selbst auf geraden Strecken ständig an der Schienenkopf-Flanke schleift. Hinzu kommt, daß die zylindrischen Laufflächen der Räder die Kurvenfahrt nicht erleichtern, wie das bei den bekannten symmetrischen Eisenbahn-Radsätzen mit konischen Laufflächen der Räder der Fall ist. Die Folge dieser schlechten Laufeigenschaften sind ein erhöhter Verschleiß, verbunden mit Geräuschentwicklung und ein erhöhter Energieverbrauch und daher erhöhte Unterhaltungskosten im Betrieb.Previous designs of funicular drives as single-axle wheel sets two-axle wagons or as multi-axle bogies have two unequal designs Wheels always of the same diameter, one wheel having two flanges, the other however has no wheel flange. The treads of both wheels of the wheelset are cylindrical. A disadvantage of this design of the wheel sets is poor running properties even on straight sections of the route, since the pull rope is inevitable on aerial tramways must attack eccentrically to the center of gravity of the symmetrically built car because on the Route two strands of rope side by side. This eccentricity means that a wheel flange is constantly attached to the Rail head flank grinds. In addition, the cylindrical treads of the wheels Do not make cornering easier, as is the case with the well-known symmetrical railway wheel sets with conical treads of the wheels. The consequence of this bad Running properties are increased wear, associated with noise and a increased energy consumption and therefore increased maintenance costs in operation.

Zur Verbesserung der Laufeigenschaften von Standseil-Pendelbahnen sind beispielsweise aus der AT 384 783 B oder der AT 384 587 B starre Radsätze mit zwei unterschiedlich gestalteten Rädern, wobei ein Rad durch zwei Führungselemente beidseitig geführt wird, bekannt. Allerdings entstehen beim Überfahren der Schienenlücken im Bereich der Ausweiche ungünstige Führungsverhältnisse und berücksichtigen diese Konstruktionen auch nicht die Folgen des exzentrischen Kraftangriffes des Zugseiles, was auch für den Gegenstand der FR 2 557 054 A1 zutrifft. For example, to improve the running properties of funicular aerial tramways the AT 384 783 B or the AT 384 587 B rigid wheel sets with two different designs Wheels, wherein a wheel is guided on both sides by two guide elements. However, when crossing the rail gaps in the area of the diverter unfavorable management relationships and do not take these constructions into account Consequences of the eccentric force attack of the pull rope, which is also the subject of FR 2 557 054 A1 applies.

Die Aufgabe der vorliegenden Erfindung besteht darin, weitere Verbesserungen der Laufeigenschaften in Form einer Erleichterung der Fortbewegung im Gleis, sowohl auf den geraden Strecken, als auch insbesondere in den Gleisbögen zu erzielen. Zudem soll auch der Exzentrizität des angreifenden Zugseiles entgegengewirkt werden.The object of the present invention is to further improve the Running characteristics in the form of facilitating locomotion on the track, both on the straight lines, as well as in particular to achieve in the track arches. In addition, the Eccentricity of the attacking pull rope can be counteracted.

Gelöst wird diese Aufgabe durch ein Laufwerk bzw. einen Radsatz mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1 bzw. 3, wonach das beidseitig geführte Rad zumindest eines Radsatzes einen kleineren Nenndurchmesser als das andere Rad aufweist, und dieses andere Rad mit dem größeren Nenndurchmesser durch ein Führungselement an der Gleisinnenseite geführt wird. Die Lauffläche des großen Rades kann im äußeren Teil auch zylindrisch ausgebildet werden.This task is solved by a running gear or a wheel set with the characteristics of the characterizing part of claim 1 or 3, according to which the double-sided wheel at least one wheel set has a smaller nominal diameter than the other wheel, and this other wheel with the larger nominal diameter through a guide element on the Track inside is guided. The tread of the big wheel can also be in the outer part be cylindrical.

Die Erfindung erzielt eine erhebliche Verbesserung der Laufeigenschaften dadurch, daß sie die Vorzüge des bekannten Eisenbahn-Radsatzes mit den Vorzügen des bisherigen Standseilbahn-Radsatzes vereinigt. Dabei wird die Möglichkeit des eingleisigen Streckenausbaues und der bekannten automatischen Abt'schen Ausweiche der Standseil-Pendelbahnen erhalten. Dies wird erreicht, indem der Radsatz durch zwei der drei Führungselemente geführt wird, derart, daß im ersten Fall ein gleichbleibendes begrenztes Spurspiel auf der gesamten Strecke und im zweiten Fall ein größeres Spurspiel in Teilen der Ausweiche vorhanden ist. Dieses ermöglicht bei Radlaufflächen mit nach außen abnehmenden Durchmessern in geraden Strecken den bekannten abgehackten Sinuslauf und es bewirkt wegen der ungleichen Laulkreisdurchmesser beim Anlauf an das äußere Führungselement auch eine Erleichterung der Kurvenfahrt und verringert die Entgleisungsgefahr. Der exzentrische Kraftangriff des Zugseiles bewirkt dabei in bekannter Weise beim zweiachsigen Fahrzeug eine seitliche Verschiebung zur Gegenseite hin, beim Drehgestellfahrzeug hingegen eine gegenläufige Verdrehung der beiden Drehgestelle im Gleis. Die ungleich groß ausgeführten Nenndurchmesser der beiden Räder kompensieren aber einen Teil des exzentrischen Kraftangriffes des Zugseiles. Das eine Rad mit dem kleineren Nenndurchmesser wird durch zwei Führungselemente geführt und befindet sich im Hinblick auf die Ausweiche stets außen, seine Lauffläche fällt nach außen ab. Das andere Rad des Radsatzes mit einem größeren Nenndurchmesser ist im äußeren Teil zylindrisch und im inneren Teil mit einem nach außen abnehmenden Durchmesser gestaltet und wird durch höchstens ein Führungselement innen geführt; es ermöglicht in bekannter Weise das Überfahren der Schienenlücken im Bereich der Ausweiche.The invention achieves a significant improvement in running properties in that it the advantages of the well-known railway wheel set with the advantages of the previous one Funicular wheelset united. Thereby the possibility of single track Route expansion and the well-known automatic Abt dodge of the funicular aerial tramway receive. This is accomplished by putting the wheelset through two of the three Guide elements is guided such that in the first case a constant limited Track play along the entire route and in the second case a larger track game in parts of the Dodge is available. This enables the outside of wheel arches decreasing diameters in straight lines the well-known chopped sinus and it causes because of the uneven Laulkreisdiameter when starting on the outside Guide element also facilitates cornering and reduces the Danger of derailment. The eccentric force attack of the pull rope causes in a known For a two-axle vehicle, move it sideways to the opposite side Bogie vehicle, however, a counter-rotation of the two bogies in the Track. However, the unequal nominal diameters of the two wheels compensate part of the eccentric force attack of the pull rope. One bike with the smaller one Nominal diameter is guided by two guide elements and is in view on the switch always outside, its tread sloping outwards. The other wheel of the Wheelset with a larger nominal diameter is cylindrical in the outer part and inner part is designed with an outwardly decreasing diameter and is made by guided at most one guide element inside; it allows that in a known manner Driving over the rail gaps in the area of the dodge.

Der Radsatz kann in Form metallischer Räder 1, 2 mit stählernen Spurkränzen 4, 5, 8 als Führungselemente ausgeführt sein, wobei das Gleis der Bahn aus zwei metallischen Schienen besteht. Der gleiche Erfolg ist auch erzielbar, wenn anstatt der Spurkränze 4, 5, 8 andere Führungselemente, wie Führungsrollen oder Führungsschienen, am Fahrzeug verwendet werden und das Gleis zusätzlich horizontale Führungskonstruktionen erhält, sofern ein entsprechendes Spurspiel 6 gewährleistet ist. Die Erfindung betrifft starre Einzelradsätze oder aus solchen zusammengesetzte mehrachsige Laufwerke von Standseilbahnen mit Pendelbetrieb, die eingleisig mit Abt'scher Ausweiche ausgeführt sind. Sie bezweckt eine Erleichterung der Fortbewegung im Gleis, insbesondere auch in Gleisbögen und soll auch der Exzentrizität 11 des angreifenden Zugseiles 12 entgegenwirken. Der Radsatz besteht aus zwei ungleich ausgebildeten Rädern 1 und 2, die mit einer starren Achse 3 verbunden sind. Die Räder 1 und 2 können ungleich große Nenndurchmesser haben. Das äußere kleinere Rad 1 wird durch zwei Führungselemente 4 und 5 beidseitig geführt und ermöglicht ein Spurspiel 6 und es hat eine mit nach außen abnehmendem Durchmesser gestaltete Radlauffläche 7. Das innere größere Rad 2 wird nur durch höchstens ein Führungselement 8 innen geführt und seine Lauffläche erhält im inneren Teil 9 einen nach außen abnehmenden Durchmesser, im äußeren Teil 10 hingegen ist es zylindrisch. Die Führungselemente können entweder auf den Rädern oder entlang des Gleises unter Einhaltung des Spurspieles angebracht sein.Using the attached figure, in which an embodiment of the wheel set is an example is shown, the features of the invention are explained in more detail.
