Abstract
Description
Die Erfindung betrifft ein Niederflur-Schienenfahrzeug mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a low-floor rail vehicle with the features of the preamble of claim 1.
Triebzüge und Wagenzüge für den auf Vollbahnen betriebenen Nahverkehr weisen Fußbodenhöhen von 900 bis 1200 mm auf. Eine deutliche Reduzierung der Fußbodenhöhe auf 550 bis 750 mm hat einschneidende Konsequenzen auf die Ausbildung des Laufwerks. Insbesondere bei Triebzügen ist die Unterbringung der elektrischen Ausrüstung, vor allem des Antriebs, eine die räumliche Aufteilung und die Wagenkasten-Struktur beeinflussende Rahmenbedingung. Bisherige Lösungen oder Lösungsvorschläge beinhalten immer dann, wenn über die gesamte Zuglänge ein gleichförmig niedriger, nicht durch Stufen oder Rampen unterbrochener Fußboden vorgesehen ist, einen Verzicht auf die Ausbildung des Laufwerks als Drehgestell. So werden z.B. Einzelachslaufwerke, die an Gelenkportalen oder dem Wagenende angeordnet sind, oder Einzelradlaufwerke in Verbindung mit Portalen angewendet, bzw. vorgeschlagen. Die Nachteile von Einachs- oder Einzelradlaufwerken, wie unzureichende Radialeinstellung des vorlaufenden Radsatzes im Bogeneinlauf, unzureichende Abfederung und Geräuschisolierung, hohe Radsatzlast, Übertragung von Traktions-Reaktionsmomenten auf den Wagenkasten, können durch die Ausführung des Laufwerks als Drehgestell vermieden werden.Multiple units and wagon trains for local rail traffic have floor heights of 900 to 1200 mm. A significant reduction in the floor height to 550 to 750 mm has drastic consequences for the design of the drive. In the case of multiple units in particular, the accommodation of the electrical equipment, especially the drive, is a general condition influencing the spatial division and the body structure. Previous solutions or proposed solutions always include the design of the bogie as a bogie if a uniformly low floor is provided over the entire train length and is not interrupted by steps or ramps. For example, Single-axis drives, which are arranged on articulated portals or the end of the car, or single-wheel drives used in connection with portals, or proposed. The disadvantages of single-axle or single-wheel drives, such as inadequate radial adjustment of the leading wheelset in the sheet inlet, insufficient cushioning and noise insulation, high axle load, transmission of traction reaction moments to the car body, can be avoided by designing the drive as a bogie.
Aus der älteren Anmeldung DE P 42 13 948 ist die Ausführung eines Gelenkzuges bekannt, dessen Wagenkästen in einem Punkt kardanisch beweglich miteinander verbunden sind und durch entsprechende Ausbildung des Koppelpunktes auch hohe Pufferkräfte übertragen können. Die Wagenkästen des mindestens zweiteiligen Zuges sind über ein elastisches Verbindungselement mit einem beiden Wagenkästen gemeinsamen Drehpunkt miteinander verbunden. Jedem Wagenkasten ist am Gelenkende ein Radpaar zugeordnet, das mit dem Radpaar des benachbarten Wagenkastens über einen Rahmen verbunden ist. Die Wagenkästen sind über ihr gemeinsames Verbindungselement, Wiege und Sekundärfederung auf dem Laufwerk gelagert. Zur Erzielung eines durchgehend niedrigen Fußbodens sind die Radpaare als Losräder ausgebildet, die über einen tief liegenden Führungsrahmen miteinander verbunden sind.From the older application DE P 42 13 948 the execution of an articulated train is known, the car bodies of which are gimbally movably connected at one point and by appropriate design of the coupling point can also transmit high buffer forces. The car bodies of the at least two-part train are connected to one another via a flexible connecting element with a pivot point common to both car bodies. Each car body is assigned a pair of wheels at the end of the joint, which is connected to the wheel pair of the adjacent car body via a frame. The car bodies are mounted on the drive via their common connecting element, cradle and secondary suspension. To achieve a consistently low floor, the pairs of wheels are designed as idler wheels which are connected to one another via a low-lying guide frame.
Aus der DE 38 08 593 A1 ist die Ausführung eines Drehgestells bekannt, dessen angetriebene Radpaare durch eine tiefliegende Verbindungswelle mechanisch gekuppelt sind und so auch bei großen Raddurchmessern eine niedrige Anordnung des Fußbodens zwischen den Rädern ermöglicht wird. Bei der Ausführung als Triebdrehgestell sind die Räder eines Führungsrahmens über Getriebe und eine tiefliegende Welle torsionssteif miteinander verbunden.From DE 38 08 593 A1, the design of a bogie is known, the driven wheel pairs of which are mechanically coupled by a low-lying connecting shaft, thus enabling a low arrangement of the floor between the wheels even with large wheel diameters. In the design as a powered bogie, the wheels of a guide frame are connected to each other via torsion-resistant gears and a low-lying shaft.
Aufgabe der Erfindung ist es, einen Gelenkzug als Niederflur-Schienenfahrzeug mit drehgestellähnlichen Laufwerken zu schaffen.The object of the invention is to provide an articulated train as a low-floor rail vehicle with bogie-like drives.
Erfindungsgemäß werden bei einem Niederflur-Schienenfahrzeug mit einem durchgehenden stufen- und rampenlosen Mittelgang, bei dem benachbarte Wagenkästen in einem Punkt räumlich beweglich miteinander verbunden sind, wobei jedem Wagenkastenende ein Radpaar oder Radsatz zugeordnet ist und die Radpaare mit den Radpaaren oder dem Radsatz eines benachbarten Wagenkastens über einen Laufwerksrahmen oder ein Drehgestell verbunden sind, und die Radpaare oder Radsätze angetrieben oder nicht angetrieben sein können, die Radpaare derart über Lenker zwischen Laufwerks- oder Drehgestellrahmen und Wagenkasten geführt, daß sich die Radpaare in Abhängigkeit von der Stellung des Wagenkastens im Gleisbogen annähernd oder exakt radial einstellen.According to the invention, in a low-floor rail vehicle with a continuous, stepless and rampless central aisle, in which adjacent car bodies are spatially movably connected to one another, with each car body end being assigned a wheel pair or wheel set and the wheel pairs with the wheel pairs or the wheel set of an adjacent car body are connected via a running gear frame or a bogie, and the wheel pairs or wheel sets can be driven or not driven, the wheel pairs are guided over the handlebars between the running gear or bogie frame and the car body in such a way that the wheel pairs are in Depending on the position of the car body in the curve, set it approximately or exactly radially.
Nach einer Ausführung der Erfindung sind die Radpaare über die Primärfederung mit dem Laufwerks- oder Drehgestellrahmen längselastisch und über die Lenker starr mit dem Wagenkasten verbunden.According to one embodiment of the invention, the wheel pairs are longitudinally elastic via the primary suspension with the running gear or bogie frame and rigidly connected to the car body via the handlebars.
Nach einer anderen Ausführung der Erfindung sind die Radpaare über die Primärfederung längselastisch mit dem Laufwerks- oder Drehgestellrahmen und über in Buchsen mit radialer Weichheit gelagerte Lenker längselastisch mit dem Wagenkasten verbunden.According to another embodiment of the invention, the pairs of wheels are connected in a longitudinally elastic manner to the undercarriage or bogie frame via the primary suspension and in a longitudinally elastic manner to the car body via links mounted in bushings with radial softness.
Bei dieser zweiten Ausführung erfolgt die Abstimmung der Längscharakteristik der Federsysteme Primärfederung und Buchse so, daß gekoppelte Radpaare sich aufgrund der Rad-Schiene-Geometrie im Bogen radial einstellen können. Die Radpaare behalten durch Anordnung der Lenker zwischen Laufwerks-, bzw. Drehgestellrahmen und Wagenkasten auch bei Überlagerung von Traktionskräften ihre radiale Einstellung bei. Durch überradiale Einstellung der elastisch angelenkten Radpaare in Abhängigkeit vom Bogenradius kann das aus dem Anlaufen des bogenäußeren Rades resultierende Rückdrehmoment kompensiert werden.In this second embodiment, the longitudinal characteristics of the spring systems primary suspension and bush are matched so that coupled wheel pairs can adjust radially due to the wheel-rail geometry in the arc. By arranging the handlebars between the bogie or bogie frame and the car body, the wheel pairs maintain their radial setting even when traction forces are superimposed. By over-radial adjustment of the elastically articulated wheel pairs depending on the arc radius, the back torque resulting from the start of the wheel on the outside of the arc can be compensated.
Das Losradpaar wird über zwei Lenker, die zwischen Führungsrahmen und Wagenkasten angeordnet sind, so angelenkt, daß eine radiale Einstellung im Gleisbogen begünstigt wird. Hierzu werden die Lenker gegenüber der Fahrzeuglängsachse schräg angeordnet, die Primärfeder mit definierter Längs- und Querelastizität, z.B. als Flexicoilfeder, ausgeführt und die Lenker an beiden Enden mit elastischen, kardanisch beweglichen Buchsen ausgestattet.The pair of idler wheels is articulated via two handlebars, which are arranged between the guide frame and the car body, in such a way that radial adjustment in the track curve is favored. For this purpose, the handlebars are arranged at an angle to the vehicle's longitudinal axis, the primary spring with defined longitudinal and transverse elasticity, e.g. As a flexicoil spring, the handlebars are equipped with elastic, gimbal-type bushings at both ends.
Die Wagenkasten- bzw. lagerseitige elastische Lagerung der Lenkerstangen ist so ausgeführt, daß die Längswege von mindestens der Größenordnung, wie bei der Radpaarfederung gegenüber dem Laufwerksrahmen vorhanden sind, bei einem Kraftniveau zuläßt, das deutlich kleiner ist, als das aus der Rad-Schiene-Geometrie resultierende Längskraftniveau an den Radaufstandspunkten. Damit wird die freie Radialeinstellung des freilaufenden Radpaares nicht behindert. Durch Anstellung der Lenkerstangen in einem definierten Winkel wird erreicht, daß Traktionskräfte das radial eingestellte Radpaar nur in Wirkrichtung der Traktionskräfte parallel verschieben, nicht jedoch drehen.The car body or bearing-side elastic mounting of the handlebars is designed so that the longitudinal paths of at least the order of magnitude, as is the case with the wheel pair suspension with respect to the running gear frame, at a force level which is significantly smaller than the longitudinal force level at the wheel contact points resulting from the wheel-rail geometry. This does not impede the free radial setting of the free-running pair of wheels. By adjusting the handlebars at a defined angle, it is achieved that traction forces only move the radially set pair of wheels in parallel in the direction of action of the traction forces, but do not turn them.
