Description

Die Erfindung betrifft ein Schienenfahrzeug, insbesondere einen Stadtbahnwagen, im wesentlichen gebildet aus zumindest zwei gelenkig miteinander verbundenen Wagenkastenteilen und einem unterhalb des Gelenkes angeordneten Laufwerk.The invention relates to a rail vehicle, in particular a light rail car, essentially formed from at least two car body parts which are connected to one another in an articulated manner and a running gear arranged below the joint.

Ein Schienenfahrzeug mit den vorgenannten Merkmalen gehört aufgrund einer Vielzahl ausgeführter Konstruktionen zum Stand der Technik. Bei dem Laufwerk handelt es sich in aller Regel um ein doppelachsiges Laufdrehgestell mit Radsätzen.A rail vehicle with the aforementioned features is part of the prior art due to the large number of designs that have been carried out. The drive is usually a double-axle bogie with wheelsets.

Der Erfindung liegt die Aufgabe zugrunde, einen Stadtbahn­wagen der gattungsgemäßen Art im Bereich seines Gelenkes und des dortigen Laufwerkes so zu gestalten, daß mit möglichst wenig Aufwand eine niedrige, fahrgastfreundliche Fußbodenhöhe, ein geringeres, für kleineren Energieverbrauch günstiges Eigengewicht und eine weitgehende Reduzierung von Verschleiß zwischen Rad und Schiene erzielbar sind.The invention has for its object to design a light rail car of the generic type in the area of its joint and the drive there so that with as little effort as possible, a low, passenger-friendly floor height, a lower, for low energy consumption, its own weight and a substantial reduction in wear between Wheel and rail can be achieved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Laufwerk zwei Losräder, einen unterhalb der Radmittenebene liegenden flachen Laufwerkrahmen und einen im Laufwerkrahmen überwiegend eingebetteten, daran höhenverschiebbar geführten Gelenkträger aufweist, wobei an diesem Gelenkträger ein por­talartig ausgebildeter, schmaler Mittenspant angreift, der über eine das Laufwerk bei Kurven- sowie Kuppen- und Mulden­fahrt in winkelhalbierende Stellungen steuernde Hebelanord­nung mit den Wagenkastenteilen in Wirkverbindung steht.This object is achieved in that the drive has two idler gears, a flat drive frame located below the wheel center plane and an articulated support that is predominantly embedded in the drive frame and is guided so as to be vertically displaceable, a gantry-shaped, narrow center frame acting on this articulated support, which engages over a drive when cornering, as well as driving troughs into halving positions, the lever arrangement that controls the car body parts is in operative connection.

Das Laufwerk im Gelenkbereich hat zwei Räder 3, die jeweils als doppelt gelagerte Losräder unabhängig voneinander rotie­ren können. Auf Lagergehäusen 3a der Losräder 3 stützt sich ein unterhalb der Radmittenebene in Wagenquerrichtung ange­ordneter flacher Laufwerkrahmen 4 über Gummifedern 5 ab, die auch eine teilweise radiale Einstellung der Losräder 3 zur Schiene, speziell bei deren Einlauf von der Geraden in eine Kurve, in selbsttätiger Weise ermöglichen. Parallel zu den Gummifedern 5 arbeiten Stoßdämpfer 6. Ein überwiegend im Lauf­werkrahmen 4 eingebetteter Gelenkträger 7 wird über Mitnehmer 7a an Anschlagstücken 4a des Rahmens 4 in Längs- und Querrichtung des Fahrzeuges geführt. Zum vertikalen Abfedern des Gelenkträ­gers 7 dienen zwei Luftfedern 8, die jeweils zwischen dem Lauf­werkrahmen 4 und der Unterseite von entsprechend erhöhten Konso­len 7b an den Enden des Gelenkträgers 7 angeordnet sind.The drive in the articulated area has two wheels 3, each of which can rotate independently of one another as double-bearing idler wheels. On bearing housings 3a of the idler gears 3, a flat drive frame 4, which is arranged below the wheel center plane in the transverse direction of the wagon, is supported by rubber springs 5, which also enable a partial radial adjustment of the idler gears 3 to the rail, especially when they enter the straight line into a curve, in an automatic manner . Shock absorbers 6 work in parallel with the rubber springs 5. A joint carrier 7, which is predominantly embedded in the drive frame 4, is guided in the longitudinal and transverse directions of the vehicle via drivers 7a on stop pieces 4a of the frame 4. For the vertical cushioning of the hinge bracket 7, two air springs 8 are used, each of which is arranged between the drive frame 4 and the underside of correspondingly raised brackets 7b at the ends of the hinge bracket 7.

Die Verbindung der Wagenkastenteile 1 und 2 miteinander und mit dem Gelenkträger 7 erfolgt über eine mehrteilige Kugelpfannen-­Konstruktion, die im wesentlichen aus einer Bettung 7c in der Mitte des Gelenkträgers 7, einem aus Unterteil und Oberteil ge­bildeten Kugelkörper 9 und einer oberen Bettung 1b eines Ausle­gers la des in Zeichnungsebene linken Wagenkastenteiles 1 besteht. Ein Ausleger 2a des rechten Wagenteiles 2 erstreckt sich zwischen die beiden Teile des Kugelkörpers 9. Ein Bolzen 10 mit einem aufgesetzten Spurpilz 10a sichert die vorbeschriebene Kugel­pfannen-Verbindung, wobei zwischen dem Bolzen 10 und den von ihm durchgriffenen Bohrungen ausreichend Spiel im Hinblick auf die Knickbewegungen des Gelenkes bei Mulden- und Kuppen­fahrt besteht. Der Spurpilz 10a des Bolzens 10 unterstützt einen nachfolgend näher beschriebenen Mittenspant 11 in dessen Quermitte.The connection of the car body parts 1 and 2 with each other and with the hinge bracket 7 takes place via a multi-part ball socket construction, which essentially consists of a bed 7c in the middle of the hinge bracket 7, a spherical body 9 formed from a lower and upper part and an upper bed 1b of a boom la of the left body part 1 in the drawing plane. A boom 2a of the right car part 2 extends between the two parts of the spherical body 9. A bolt 10 with an attached mushroom 10a secures the ball socket connection described above, there being sufficient play between the bolt 10 and the bores penetrated by it with regard to the bending movements of the joint during trough and crest travel. The toe mushroom 10a of the pin 10 supports a central frame 11, described in more detail below, in the transverse center thereof.

Der Mittenspant 11 ist portalartig und besonders schmal ausge­bildet. Er erstreckt sich in Fahrzeugquerrichtung unterhalb einer üblicherweise den Durchgang zwischen den Wagenkastentei­len 1 und 2 abdeckenden zweiteiligen Drehscheibe 12 bis kurz vor die Räder 3 und verläuft im weiteren, die Räder 3 horizon­tal übergreifend (siehe Fig. 2), senkrecht nach oben bis zu seinem nicht dargestellten Dachabschnitt. Der Mittenspant 11 liegt gegen die Oberseite der Konsolen 7b des Gelenkträgers 7 an und ist daran angeschraubt. Der Mittenspant 11 dient zum einen der Aufnahme von Dichtungsbälgen 13, die jeweils an den Wagenkastenteilen 1 und 2 befestigt sind und den Gelenkbereich vollständig abschirmen; vor allem aber wird mit Hilfe des Mit­tenspantes 11 das Laufwerk so gesteuert, daß winkelhalbierende Stellungen sowohl bei Kurven- als auch bei Mulden- und Kuppen­fahrt vorliegen. Dazu ist an beiden Seiten des Mittenspantes 11 jeweils ein zweiarmiger Hebel 11a um seine Mitte - in der Höhe verschiebbar bzw. elastisch - schwenkbar gelagert, wobei an den Enden der zweiarmigen Hebel 11a und an den Wagenkastenteilen 1 und 2 jeweilige Verbindungshebel 11b kardanisch angreifen. Die mittigen Schwenkpunkte der zweiarmigen Hebel 11a sind in der Vertikalebene fluchtend mit der Kugelpfannen-Verbindung und dem Gelenkpunkt einer nicht dargestellten Anlenkung zwischen Mit­tenspant 11 und Wagenkastenteilen 1 und 2 im Dachbereich ange­ordnet. In der Horizontalen fluchten die wagenseitigen, karda­nischen Gelenkpunkte der Verbindungshebel 11b mit den mittigen Schwenkpunkten der zweiarmigen Hebel 11a. Ebenso liegen die kardanischen Gelenke an den Enden der zweiarmigen Hebel 11a in einer gemeinsamen Achse mit deren mittigem Schwenkpunkt. Die durch die vorbeschriebene Hebelanordnung erzeugten Kräfte werden über den Mittenspant 11 und den Gelenkträger 7 auf den Lauf­werkrahmen 4 und dessen Losräder 3 übertragen. Um Zwänge zu vermeiden, die bei Abweichungen der Achsstellung von der ide­alen Stellung der Räder 3 beim Ein- und Ausfahren in bzw. aus Kurven denkbar wären, sind die Mitnahmeeinrichtungen - z.B. der Mittenspant 11 - hinreichend elastich verformbar und ge­nügend Spiele vorgesehen, beispielsweise zwischen den Mitneh­mern 7a des Gelenkträgers 7 und den Anschlagstücken 4a des Laufwerkrahmens 4.The central frame 11 is portal-like and particularly narrow. It extends in the transverse direction of the vehicle below a two-part turntable 12, which usually covers the passage between the body parts 1 and 2, up to just in front of the wheels 3 and, furthermore, extends horizontally across the wheels 3 (see FIG. 2), vertically up to it shown roof section. The center frame 11 lies against the top of the brackets 7b of the joint support 7 and is screwed to it. The central frame 11 serves on the one hand to accommodate sealing bellows 13, which are each fastened to the body parts 1 and 2 and completely shield the joint area; Above all, however, the drive is controlled with the aid of the center frame 11 in such a way that bisecting positions are present both when cornering and when troughs and crests. For this purpose, a two-armed lever 11a is pivotally mounted on both sides of the center frame 11 about its center - displaceable in height or elastically - gimbaling the respective connecting levers 11b at the ends of the two-armed lever 11a and on the car body parts 1 and 2. The center pivot points of the two-armed levers 11a are aligned in the vertical plane with the ball socket connection and the articulation point of an articulation (not shown) between the center frame 11 and the body parts 1 and 2 in the roof area. In the horizontal plane, the gimbal-side articulation points of the connecting levers 11b are aligned with the central pivot points of the two-armed levers 11a. Likewise, the cardanic joints at the ends of the two-armed levers 11a lie in a common axis with their central pivot point. The forces generated by the lever arrangement described above Transfer via the center frame 11 and the hinge bracket 7 to the drive frame 4 and its idler gears 3. In order to avoid constraints that would be conceivable in the event of deviations in the axial position from the ideal position of the wheels 3 when entering and exiting in or out of curves, the driving devices - for example the central frame 11 - are sufficiently elastically deformable and sufficient play is provided, for example between the Carriers 7a of the joint support 7 and the stop pieces 4a of the drive frame 4.

Eine Stabilisierung des Laufwerkrahmens 4 gegenüber Kippbewe­gungen um die Mittenachse der Räder 3 wird gemäß Fig. 4 durch Streben 4b erzielt, die winkelsteif am Laufwerkrahmen 4 ange­schlossen und gegen Anschlagflächen 11c des Mittenspantes 11 höhenverschiebbar abgestützt sind.A stabilization of the drive frame 4 with respect to tilting movements about the center axis of the wheels 3 is achieved according to FIG. 4 by struts 4b, which are connected to the drive frame 4 at an angle-stiffness and are supported in a vertically displaceable manner against stop surfaces 11c of the center frame 11.

Bei dem gemäß Fig. 5 und 6 abgewandelten Laufwerk sind - nach dem Prinzip der EP-B- 0 135 877, Fig. 2 - die Losräder 3 je­weils um eine außerhalb der Spurweite liegende senkrechte Achse schwenkbar mit dem Laufwerkrahmen 4 verbunden, der dem­entsprechend ausgebildet ist. Die beiden Losräder 3 sind durch eine Spurstange 15 in ihrer Schwenkbewegung gekoppelt. Auf die­se Weise werden ideale Radeinstellungen im Gleisbogen erzielt.5 and 6 modified - according to the principle of EP-B-0 135 877, Fig. 2 - the idler gears 3 are each pivotally connected to the drive frame 4 about a vertical axis lying outside the track width, which is designed accordingly is. The two idler gears 3 are coupled in their pivoting movement by a tie rod 15. In this way, ideal wheel settings are achieved in the track curve.

Der Gelenkbereich ist zum Fahrgastraum hin durch eine Gelenk­verkleidung 14 abgedeckt.The joint area is covered towards the passenger compartment by a joint cover 14.
