Description

Die Erfindung betrifft eine Antriebseinheit für Schienentriebfahrzeuge Antriebseinheit für Schienentriebfahrzeuge nach dem Oberbegriff des Hauptanspruches.The invention relates to a drive unit for rail locomotives. Drive unit for rail locomotives according to the preamble of the main claim.

Es sind Antriebe für Schienentriebfahrzeuge bekannt, bei denen ein elektrischer Antriebsmotor üblicherweise unter Zwischenschaltung eines Getriebes einen zugeordneten Radsatz mit dem Antriebsmoment beaufschlagt, wobei die Verbindung zwischen der aus dem Antriebsmotor und dem Getriebe gebildeten Antriebseinheit und dem Radsatz durch eine kardanisch beweglich verbundene Hohlwelle erfolgt, welche konzentrisch zur Radachse des Radsatzes angeordnet ist.There are drives for rail vehicles known in which an electric drive motor usually applies the drive torque to an assigned wheel set with the interposition of a transmission, the connection between the drive unit formed from the drive motor and the transmission and the wheel set being effected by a gimbal-connected hollow shaft, which is arranged concentrically to the wheel axis of the wheelset.

Von Nachteil bei den bekannten Antrieben ist die Anordnung der Stützlager für die Rotorwelle, wobei die Stützlager den Rotor zwischen sich nehmen und das Ritzel auf dem zum Getriebe weisenden überstehenden Wellenstumpf fliegend gelagert ist, so daß das abtriebsseitige Stützlager der Rotorwelle zusätzlich zum Antriebsmoment auch ein Biegemoment der Rotorwelle aufnehmen muß. Hierdurch ergeben sich Probleme hinsichtlich der Gestaltung des Lagers, da dieses einerseits wegen der erwünschten hohen Motordrehzahl nicht zu groß werden soll, da aber andererseits das gewünschte hohe Drehmoment einen großen Lagerdurchmesser erfordert.A disadvantage of the known drives is the arrangement of the support bearings for the rotor shaft, wherein the support bearings take the rotor between them and the pinion is overhung on the protruding shaft end facing the gearbox, so that the output-side support bearing of the rotor shaft also has a bending moment in addition to the drive torque the rotor shaft must accommodate. This results in problems with regard to the design of the bearing, since on the one hand it should not become too large because of the desired high engine speed, but on the other hand the desired high torque requires a large bearing diameter.

Diesen divergierenden Leistungsmerkmalen für die Auslegung der Stützlager überlagert sich die bereits erwähnte hohe radiale Lagerbelastung aus den Zahnkräften zwischen Ritzel und Getriebezahnrad durch die fliegende Ritzenlagerung. Eine beliebige Vergrößerung des ritzelseitigen Stützlagers der Rotorwelle ist nur in beschränktem Maße möglich, da die zum Einsatz gelangenden Antriebsmotoren auf Grund der vorherrschenden Platzverhältnisse eine bestimmte Größe nicht überschreiten dürfen und daher mit relativ hohen Drehzahlen betrieben werden, die die Lagergröße nach oben einschränken.The above-mentioned high radial bearing load from the tooth forces between the pinion and the gear wheel is superimposed on these divergent performance characteristics for the design of the support bearings by the flying pinion bearing. An arbitrary enlargement of the pinion-side support bearing of the rotor shaft is only possible to a limited extent, since the drive motors used are due to the prevailing ones Space conditions must not exceed a certain size and are therefore operated at relatively high speeds that limit the size of the bearings.

Ein weiteres Problem bei herkömmlichen Antrieben resultiert daraus, daß der Antriebsmotor einerseits und das Getriebe andererseits als einzelne Komponenten zur Montage gelangen und ihre Handhabung einigen Aufwand erfordert.Another problem with conventional drives results from the fact that the drive motor, on the one hand, and the gear, on the other hand, are installed as individual components and their handling requires some effort.

Ein Einzelradantrieb für Fahrzeuge insbesondere für Eisenbahnfahrzeuge ist aus der DE-A 846 107 bekannt, bei welchem am abgefederten Rahmen der Lokomotive ein Antriebsmotor fest gelagert ist, dessen Welle in zwei endseitig angeordneten Lagern abgestützt ist. Ein auf der Welle sitzendes Ritzel steht mit einem großen Zahnrad in Eingriff, welches mittels einer Schraubenfeder mit dem anzutreibenden Treibrad verbunden und von einem geteilten Schutzkasten umschlossen ist. Das abtriebseitige Stützlager der Motorwelle ist bei diesem Einzelradantrieb von einem Lagerschild gehalten, der an einem mit dem Motorgehäuse verbundenen geteilten Schutzkasten anschließt.A single wheel drive for vehicles, in particular for railway vehicles, is known from DE-A 846 107, in which a drive motor is fixedly mounted on the sprung frame of the locomotive, the shaft of which is supported in two bearings arranged at the ends. A pinion sitting on the shaft engages with a large gearwheel, which is connected to the drive wheel to be driven by means of a helical spring and is enclosed by a divided protective box. In this single wheel drive, the output-side support bearing of the motor shaft is held by a bearing plate which connects to a split protective box connected to the motor housing.

Ausgehend von diesem Stand der Technik ist es daher Aufgabe der Erfindung, eine Antriebseinheit der eingangs genannten Art zu schaffen, welche einfach zu handhaben ist und bei welcher die Lagerbelastung des ritzelseitigen Stützlagers der Rotorwelle vermindert ist, bei ansonsten gleichen Leistungsmerkmalen.Starting from this prior art, it is therefore an object of the invention to provide a drive unit of the type mentioned at the outset, which is easy to handle and in which the bearing load on the pinion-side support bearing of the rotor shaft is reduced, with otherwise the same performance features.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des einzigen Patentanspruchs gelöst.This object is achieved by the characterizing features of the only claim.

Der Vorteil der erfindungsgemäßen Gestaltung beruht darauf, daß die Einzelkomponenten, der Antriebseinheit nämlich Antriebsmotor und Getriebe, der vormontiert zum Einbau in das Schienentriebfahrzeug gelangen und nunmehr einstückig zu handhaben sind. Dabei ist erfindungsgemäß vorgesehen, daß der Antriebsmotor auf der Abtriebsseite, auf welcher das Ritzel auf der Rotorwelle angeordnet ist, kein Lagerschild aufweist, sondern daß das diesseitige Stützlager vielmehr integraler Bestandteil des gemeinsamen Gehäuses ist.The advantage of the design according to the invention is based on the fact that the individual components, namely the drive unit, namely the drive motor and transmission, which are preassembled for installation in the rail locomotive and are now to be handled in one piece. It is provided according to the invention that the drive motor on the output side on which the pinion is arranged on the rotor shaft does not have a bearing plate, but that the support bearing on this side is rather an integral part of the common housing.

Dabei ist in zweckmäßiger Weise vorgesehen, daß eine Trennfuge des gemeinsamen Gehäuses in eine Ebene gelegt ist, die parallel zur Antriebsachse verläuft. Dabei kann die Verbindung der beiden Gehäuseteile in herkömmlicher Weise mittels Zugankern erfolgen.It is expediently provided that a joint of the common housing is placed in a plane that runs parallel to the drive axis. The two housing parts can be connected in a conventional manner by means of tie rods.

Anhand eines Ausführungsbeispieles der Erfindung, das in den Zeichnungen dargestellt ist, sollen die Erfindung, besondere Vorteile und Verbesserungen der Erfindung näher erläutert und beschrieben werden.The invention, particular advantages and improvements of the invention are to be explained and described in more detail using an exemplary embodiment of the invention which is illustrated in the drawings.

Es zeigt die einzige Figur: eine schematische Darstellung einer AntriebseinheitIt shows the only figure: a schematic representation of a drive unit

In der einzigen Figur ist eine Antriebseinheit 11 dargestellt, die aus einem Antriebsmotor 12 und einem Getriebe 14, welches eine berührungslos durchgeführte Radachse 16 eines nicht näher gezeigten Radsatzes umschließt, in einem gemeinsamen Gehäuse 38 zusammengefügt ist.In the single figure, a drive unit 11 is shown, which is assembled from a drive motor 12 and a gear 14, which encloses a wheel axle 16 of a wheel set, not shown, in a common housing 38.

Wesentlich für die in der einzigen Figur gezeigten Anordnung ist die Anordnung des ritzelseitigen Stützlagers 28, welches das Ritzel 24 zwischen sich und den Rotor 22 nehmend am Ende der Rotorwelle 20 im Gehäuse 38 angeordnet ist.What is important for the arrangement shown in the single figure is the arrangement of the pinion-side support bearing 28, which, taking the pinion 24 between it and the rotor 22, is arranged in the housing 38 at the end of the rotor shaft 20.

Demgemäß unterscheidet sich die Antriebseinheit 11 von herkömmlichen Gestaltungen unter anderem dadurch, daß nur auf der dem Ritzel gegenüberliegenden Seite, das heißt in den Zeichnungen auf der linken Seite ein herkömmliches Lagerschild zur Aufnahme des Stützlagers 26 vorgesehen ist. Auf der gegenüberliegenden Seite ist anstelle des sonst üblichen Lagerschildes ein Gehäuseabschnitt vorgesehen, der Bestandteil des antriebsmotorsseitigen Gehäuseteils 38.1 ist.Accordingly, the drive unit 11 differs from conventional designs, inter alia, in that a conventional bearing plate for receiving the support bearing 26 is provided only on the side opposite the pinion, that is to say on the left in the drawings. On the opposite side, instead of the otherwise usual bearing plate, a housing section is provided, which is part of the housing part 38.1 on the drive motor side.
