Description

Die Erfindung betrifft eine Antriebseinheit für Schienentriebfahrzeuge mit einem elektrischen Antriebsmotor mit in Stützlagern gelagerter Rotorwelle, welche einen Rotor (Anker) und ein Ritzel trägt, und mit einem Getriebe, welches vom Antriebsmotor beaufschlagt ist und zum Antrieb eines Radsatzes mit diesem verbunden ist.The invention relates to a drive unit for rail vehicles with an electric drive motor with a rotor shaft mounted in support bearings, which carries a rotor (armature) and a pinion, and with a gear, which is acted upon by the drive motor and is connected to this for driving a wheel set.

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 stub pointing to 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 this 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 may not exceed a certain size due to the prevailing space conditions and are therefore operated at relatively high speeds which 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.

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.
Diese Aufgabe wird erfindungsgemäß entsprechend den kennzeichnenden Merkmalen des Patentanspruchs 1 dadurch gelöst, daß ein gemeinsames Gehäuse für den Antriebsmotor und das Getriebe vorgesehen ist und daß für die ritzelseitige Lagerung der Rotorwelle ein Stützlager am ritzelseitigen Ende der Rotorwelle 20 im Gehäuse angeordnet ist, daß das Ritzel zwischen dem ritzelseitigen Stützlager und dem Rotor des Antriebsmotors angeordnet ist.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.
This object is achieved according to the characterizing features of claim 1 in that a common housing is provided for the drive motor and the gear and that for the pinion-side mounting of the rotor shaft, a support bearing is arranged on the pinion-side end of the rotor shaft 20 in the housing that the pinion is arranged between the pinion-side support bearing and the rotor of the drive motor.

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.

In zweckmäßiger Ausgestaltung der Erfindung kann vorgesehen sein, daß eine Trennfuge des gemeinsamen Gehäuses in die Ebene, in der ursprünglich das abtriebsseitige Lagerschild angeordnet war, gelegt ist, so daß die Verbindung der beiden Gehäuseteile in herkömmlicher Weise mittels Zugankern erfolgen kann. Eine derartige Gestaltung ist insoweit vorteilhaft, als die bisher üblichen Baugruppen des Antriebsmotors mit Ausnahme des abtriebsseitigen Lagerschildes beibehalten werden können.In an expedient embodiment of the invention, it can be provided that a joint of the common housing is placed in the plane in which the output-side bearing plate was originally arranged, so that the connection of the two housing parts can take place in a conventional manner by means of tie rods. Such a design is advantageous insofar as the previously customary assemblies of the drive motor can be retained with the exception of the bearing plate on the output side.

Gemäß einer anderen zweckmäßigen Ausgestaltung der Erfindung kann aber auch vorgesehen sein, daß die aus Gründen der Einzelmontage der jeweiligen Komponenten erforderliche Trennfuge parallel zur Rotorachse gelegt ist.According to another expedient embodiment of the invention, it can also be provided that the parting line required for the individual assembly of the respective components is placed parallel to the rotor axis.

Diese und weitere vorteilhafte Ausgestaltungen der Erfindungen sind Gegenstand der Unteransprüche.These and other advantageous embodiments of the inventions are the subject of the dependent claims.

Anhand zweier Ausführungsbeispiele der Erfindung, die in den Zeichnungen dargestellt sind, 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 with reference to two exemplary embodiments of the invention which are illustrated in the drawings.
Show it:
Fig. 1
1 shows a schematic representation of a drive unit according to the first variant,
Fig. 2
is a schematic representation of a drive unit according to the second variant.

In Fig. 1 ist eine Antriebseinheit 10 dargestellt, welche aus einem Antriebsmotor 12 und einem Getriebe 14, durch welches eine Radachse 16 berührungsfrei hindurchgeführt ist, in einem gemeinsamen Gehäuse 18 zusammengesetzt ist. Das gemeinsame Gehäuse 18 ist entlang einer Trennfuge 19 in zwei Teile unterteilt, die einerseits den Antriebsmotor 12 und andererseits das Getriebe 14 aufnehmen.1 shows a drive unit 10, which is composed of a drive motor 12 and a gear 14, through which a wheel axle 16 is passed without contact, in a common housing 18. The common housing 18 is divided along a parting line 19 into two parts which, on the one hand, accommodate the drive motor 12 and, on the other hand, the transmission 14.

Der Antriebsmotor 12 besitzt in seinem Gehäuseinneren eine Rotorwelle 20 mit einem darauf angeordneten Rotor 20 sowie einem ebenfalls auf der Rotorwelle 20 befestigten Ritzel 24 und ist in zwei Stützlagern 26, 28, die sich jeweils am Wellenende der Rotorwelle 20 befinden, abgestützt. Während das Stützlager 26 in dem den Rotor 22 umschließenden Gehäuseteil 18.1 eingesetzt ist, ist das ritzelseitige Stützlager 28 in dem das Getriebe aufnehmenden Gehäuseteil 18.2 eingesetzt.The drive motor 12 has in its interior a rotor shaft 20 with a rotor 20 arranged thereon and a pinion 24 likewise fastened on the rotor shaft 20 and is supported in two support bearings 26, 28, which are each located at the shaft end of the rotor shaft 20. While the support bearing 26 in the rotor 22 enclosing Housing part 18.1 is inserted, the pinion-side support bearing 28 is inserted in the housing part 18.2 receiving the transmission.

Nicht näher gezeigt ist die Art der zur Verbindung der beiden Gehäuseteile 18.1 und 18.2 vorgesehenen Befestigungselemente, die vorzugsweise mit herkömmlichen Zugankern vorgesehen ist.The type of fastening elements provided for connecting the two housing parts 18.1 and 18.2, which is preferably provided with conventional tie rods, is not shown.

Das Getriebe 14 ist nur grob schematisch dargestellt mit einem Getriebehauptrad 30, welches auf einer Hohlwelle 32 angeordnet ist, die in Stützlagern 34, 36 abgestützt ist und an einem Ende einen Flansch 38 zur Befestigung einer Kupplung aufweist, mittels welcher die Verbindung zum hier nicht näher gezeigten die Radachse 16 aufweisenden Radsatz hergestellt wird. Wahlweise kann ein weiteres Zahnrad als Zwischenrad oder ein Zahnradpaar als Untersetzungsstufe zusätzlich im Getriebegehäuse angeordnet sein.The gear 14 is shown only roughly schematically with a main gear 30, which is arranged on a hollow shaft 32, which is supported in support bearings 34, 36 and at one end has a flange 38 for fastening a clutch, by means of which the connection to the here is not closer shown the wheel axle 16 having wheelset is produced. Optionally, a further gear wheel as an intermediate gear or a pair of gear wheels as a reduction stage can additionally be arranged in the gear housing.

Nicht gezeigt sind auch die an den Gehäuseteilen vorgesehenen herkömmlichen Befestigungsvorrichtungen, mittels welcher die Antriebseinheit 10 am Schienentriebfahrzeug befestigt wird. Die im Inneren des Gehäuses 18 im einzelnen vorgesehenen Maßnahmen zur Abdichtung des mit Öl gefüllten Gehäuseteils 18.2, der das Getriebe 14 aufnimmt, sowohl gegenüber dem den Motor 12 aufnehmenden Getriebeteil, sind bekannt und daher nicht besonders erläutert.Also not shown are the conventional fastening devices provided on the housing parts, by means of which the drive unit 10 is fastened to the rail locomotive. The measures provided in the interior of the housing 18 for sealing the oil-filled housing part 18.2, which receives the gear 14, both with respect to the gear part receiving the motor 12, are known and are therefore not specifically explained.

In Fig. 2 ist eine der Anordnung gemäß Fig. 1 nahezu identisch entsprechende Antriebseinheit 11 dargestellt, die aus einem Antriebsmotor 12 und einem Getriebe 14, welches eine berührungslos im durchgeführte Radachse 16 eines nicht näher gezeigten Radsatzes umschließt, in einem gemeinsamen Gehäuse 38 zusammengefügt ist. Demgemäß gelten für die angegebenen Bezugsziffern die gleichen Erläuterungen, wie sie bereits zu Fig. 1 gegeben wurden.FIG. 2 shows a drive unit 11 which corresponds almost identically to the arrangement according to FIG. 1 and which comprises a drive motor 12 and a gear 14 which has a contactlessly carried out wheel axle 16 encloses a wheel set, not shown, is assembled in a common housing 38. Accordingly, the same explanations apply to the specified reference numbers as have already been given for FIG. 1.

Der wesentliche Unterschied zwischen der Ausgestaltung gemäß Fig. 1 und der in Fig. 2 gezeigten Anordnung besteht darin, daß abweichend von Fig. 1 die Anordnung gemäß Fig. 2 ein Gehäuse mit einer parallel zur Radachse 16, bzw. zur Rotorachse 20 des Antriebsmotors 12 bzw. zur Hohlwelle 32 des Getriebes 14 verlaufende Trennfuge 39 aufweist, welches das gemeinsame Gehäuse 38 in ein antriebsmotorseitiges Gehäuseteil 38.1 und ein getriebeseitiges Gehäuseteil 38.2 unterteilt.The main difference between the configuration according to FIG. 1 and the arrangement shown in FIG. 2 is that, in contrast to FIG. 1, the arrangement according to FIG. 2 is a housing with a parallel to the wheel axis 16 or to the rotor axis 20 of the drive motor 12 or to the hollow shaft 32 of the transmission 14 extending joint 39 which divides the common housing 38 into a drive motor-side housing part 38.1 and a gear-side housing part 38.2.

Wesentlich für beide in den Figuren 1 und 2 gezeigten Anordnungen 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.The arrangement of the pinion-side support bearing 28, which takes the pinion 24 between it and the rotor 22 at the end of the rotor shaft 20 in the housing 38, is essential for both arrangements shown in FIGS. 1 and 2.

Beide Anordnungen, die Antriebseinheit 10 gemäß Fig. 1 wie auch die Antriebseinheit 11 gemäß Fig. 2 unterscheiden sich 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 gemäß Fig. 1 zum getriebeseitigen Gehäuseteil 18.2 und gemäß Fig. 2 Bestandteil des antriebsmotorsseitigen Gehäuseteils 38.1 ist.Both arrangements, the drive unit 10 according to FIG. 1 and the drive unit 11 according to FIG. 2 differ from conventional designs, inter alia in that a conventional bearing plate is only provided on the side opposite the pinion, that is to say in the drawings on the left Support bearing 26 is provided. On the opposite side, instead of the otherwise usual end shield, a housing section is provided which, according to FIG. 1, is part of the housing part 18.2 on the transmission side and, according to FIG. 2, is part of the housing part 38.1 on the drive motor side.
