Description

Gelenkwellenantrieb für elektrische Schienen-und Straßentriebfahrzeuge Die Erfindung bezieht sich auf einen Gelenkwellenantrieb für elektrische Triebfahrzeuge mit Kommutatorfahrmotoren, wie er beispielsweise bei Straßenbahnen und Oberleitungsomnibussen verwendet wird. Bei bekannten Antrieben dieser Art ist das eine Gelenk der Gelenkwelle mit der Motorwelle verbunden. Es hat sich gezeigt, daß die senkrechten Achsbewegungen der Treibachse, die beispielsweise durch Schienenstöße oder Fahrbahnunebenheiten hervorgerufen werden, über die Gelenkwelle auf den Läufer des antreibenden Motors einwirken, so daß die Stromabnahme am Kommutator gestört wird.Cardan shaft drive for electric rail and road locomotives The invention relates to a cardan shaft drive for electric traction vehicles with commutator drive motors, such as those used in trams and trolleybuses is used. In known drives of this type, this is one joint of the cardan shaft connected to the motor shaft. It has been shown that the vertical axis movements the driving axle, caused for example by rail joints or uneven road surfaces caused by the cardan shaft on the rotor of the driving motor act so that the current consumption at the commutator is disturbed.

Für Antriebsvorrichtungen von Kraftfahrzeugen ist es bekannt, zwischen der Gelenkwelle und der Motor-bzw. Getriebewelle einen torsionselastischen Drehstab anzuordnen, der mit der Motorwelle über eine Kardanscheibe, also über eine Kreuzgelenkkupplung, verbunden ist. Da zur Erzielung einer ausreichenden Drehelastizität der Drehstab nicht allzu kurz bemessen werden kann, erfordert eine solche Antriebsvorrichtung außer einer notwendigen Fertigungsgenauigkeit eine erhebliche Baulänge, die bei vielen elektrischen Triebfahrzeugen, besonders bei solchen mit Drehgestellen, innerhalb welcher Motor und Antrieb untergebracht werden müssen, nicht zur Verfügung steht.For drive devices of motor vehicles, it is known between the cardan shaft and the motor or. Gear shaft has a torsionally elastic torsion bar to be arranged, which is connected to the motor shaft via a cardan disk, i.e. via a universal joint coupling, connected is. As the torsion bar to achieve sufficient torsional elasticity cannot be dimensioned too short, requires such a drive device apart from a necessary manufacturing accuracy, a considerable overall length, which in many electric locomotives, especially those with bogies, within which motor and drive have to be accommodated is not available.

Gemäß der Erfindung werden diese Schwierigkeiten bei einem Gelenkwellenantrieb für elektrische Triebfahrzeuge mit Kommutatorfahrmotoren, insbesondere für Straßenbahnen oder Oberleitungsomnibusse, durch die Kombination folgender - bekannter - Maßnahmen behoben: a) Die Welle des Kommutatorfahrxnotors treibt eine in radialer und axialer Richtung nachgiebige Kupplung an; b) an die nachgiebige Kupplung ist .eine fest ge- lagerte, starre Zwischenwelle .angeschlossen, und c) die starre Zwischenwelle treibt die zur Treib- achse des Fahrzeuges führende Gelenkwelle an. Die nachgiebige Kupplung gleicht den Ungleichförmigkeitsgrad der Winkelgeschwindigkeit der Zwischenwelle aus. Es ist besonders vorteilhaft, die Zwischenwelle in einem Gehäuse zu lagern, das fest mit dem Motorgehäuse verbunden und gegebenenfalls abnehmbar ausgebildet ist.According to the invention, these difficulties in a cardan shaft drive for electric traction vehicles with commutator drive motors, in particular for trams or trolleybuses, are eliminated by the combination of the following - known - measures: a) The shaft of the commutator drive motor drives one compliant in the radial and axial directions Coupling on; b) there is a tight fit on the flexible coupling. mounted, rigid intermediate shaft .connected, and c) the rigid intermediate shaft drives the axis of the vehicle leading cardan shaft. The compliant coupling compensates for the degree of irregularity in the angular velocity of the intermediate shaft. It is particularly advantageous to mount the intermediate shaft in a housing that is permanently connected to the motor housing and, if necessary, is designed to be removable.

Nachgiebige Kupplungen sind an sich bereits bekannt, und zwar insbesondere zur Verbindung der Motorwelle und der Gelenkwelle bei Kraftfahrzeugen. Die Verwendung einer nachgiebigen Kupplung in Verbindung mit einer starren Zwischenwelle bei einem Gelenkwellenantrieb mit einem Kommutatorfahrmotor bringt jedoch den Vorteil, .daß eine Flach-Stellenbildung am Kommutator des Fahrmotors vermieden wird. Das durch die Gelenkwelle bedingte wandernde Zusatzmoment wird nämlich durch diese Anordnung praktisch völlig von der Motorwelle ferngehalten.Compliant couplings are already known per se, in particular for connecting the motor shaft and the cardan shaft in motor vehicles. The usage a flexible coupling in connection with a rigid intermediate shaft in one Cardan shaft drive with a commutator drive motor, however, has the advantage that a flat spot formation on the commutator of the drive motor is avoided. That through the propeller shaft-related additional migratory torque is namely through this arrangement practically completely kept away from the motor shaft.

In der Zeichnung ist ein Ausführungsbeispiel eines Antriebes nach der Erfindung wiedergegeben.In the drawing, an embodiment of a drive is according to reproduced the invention.

Die Motorwelle 1 des nicht dargestellten Kommutatorfahrmotors, beispielsweise eines Straßenbahntriebwagens, ist über die nachgiebige Kupplung 2 mit der starren und fest gelagerten Zwischenwelle 3 verbunden. Am rechten Ende der Zwischenwelle 3 greift der Flansch 4 mittels Kerbverzahnung an. Der Flansch 4 dient zum Anschluß der nicht dargestellten Gelenkwelle, die die angeschlossene Treibachse des Triebwagens treibt.The motor shaft 1 of the commutator travel motor, not shown, for example a tram, is via the flexible coupling 2 with the rigid and fixedly mounted intermediate shaft 3 connected. At the right end of the intermediate shaft 3, the flange 4 engages by means of serrations. The flange 4 is used for connection the propeller shaft, not shown, which is the connected drive axle of the railcar drives.

Die nachgiebige Kupplung 2 besteht aus den beiden Flanschen 5 und 6, die mit der Motorwelle 1 bzw. der Zwischenwelle 3 über eine Kerbverzahnung in Verbindung stehen. Zwischen den beiden Flanschen 5 und 6 befindet sich der Kupplungsring 7, der aus Metallsegmenten mit dazwischenliegenden Gummisegmenten besteht. Die Metallsegmente dieses Kupplungsringes 7 sind längs des Umfanges abwechselnd mit dem Flansch 5 bzw. mit dem Flansch 6 verschraubt. Auf diese Weise ergibt sich zwischen der Motorwelle 1 und der Zwischenwelle 3 die axiale und radiale Nachgiebigkeit der Kupplung 2.The flexible coupling 2 consists of the two flanges 5 and 6, which are connected to the motor shaft 1 or the intermediate shaft 3 via a serration in Connected. The coupling ring is located between the two flanges 5 and 6 7, which consists of metal segments with rubber segments in between. The metal segments this coupling ring 7 are alternately along the circumference with the flange 5 or screwed to the flange 6. This results in between the motor shaft 1 and the intermediate shaft 3, the axial and radial flexibility of the clutch 2.

Die Zwischenwelle 3 ist mittels der Lager 8 und 9 im Gehäuse 10 gelagert, das durch die Schrauben 11 mit dem Fahrmotorgehäuse 1:, verschraubt wird und somit abnehmbar ist. Das Gehäuse 10 umschließt die Zwischenwelle 3 und die nachgiebige Kupplung 2. Um einen Austritt des Schmiermittels aus den Lagern 8 und 9 zu verhindern, werden diese in bekannter Weise durch Labyrinthdichtungen abgeschlossen.The intermediate shaft 3 is supported by the bearings 8 and 9 in the housing 10, which is screwed to the traction motor housing 1 by means of the screws 11, and thus is removable. The housing 10 encloses the intermediate shaft 3 and the flexible one Clutch 2. To prevent the lubricant from escaping from bearings 8 and 9, these are closed in a known manner by labyrinth seals.

Durch die erfindungsgemäße Anordnung werden die Kräfte, die durch die Gelenkwelle auf den Flansch 4 ausgeübt werden, von der Motorwelle 1 ferngehalten, so daß der Läufer des Motors wesentlich ruhiger als bei den bekannten Anordnungen läuft und eine gleichmäßige Stromabnahme am Kommutator erzielt wird.The arrangement according to the invention, the forces caused by the PTO shaft on the Flange 4 exerted by the motor shaft 1 kept away, so that the rotor of the motor is much quieter than with the known Arrangements runs and a uniform current decrease on the commutator is achieved.
