Description

Die Erfindung betrifft ein Drehgestell für Lokomotiven nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bogie for locomotives according to the preamble of patent claim 1.

Im Drehgestellrahmen sind dabei im Allgemeinen zwei Triebradsätze mit zugehöriger Antriebseinheit angeordnet, wobei die Antriebseinheit im Drehgestellrahmen aufgehängt ist.In the bogie frame are generally arranged two drive wheels with associated drive unit, wherein the drive unit is suspended in the bogie frame.

Die einfachste Art der Aufhängung von Antriebseinheiten ist dabei der Tatzlagerantrieb. Die DE 195 30 155 A1 beschreibt eine solche Lösung, bei der der Motor auf einer Seite mit zwei Tatzlagern auf der Radachse der Triebräder abgestützt ist und auf der anderen Seite am Drehgestell federnd gehalten ist. Motor und Getriebe sind dabei achsreitend angeordnet. Bei dieser Antriebsart lastet die Masse des Motors und des Getriebes zum Großteil ungefedert auf dem Radsatz. Nachteil dieser Tatzlageranbindung ist, dass durch die Gleisunebenheiten eingebrachte Kräfte (Beschleunigungen) direkt auf den Antrieb übergeleitet werden. Dieser Effekt verstärkt sich mit Zunahme der Geschwindigkeit. Durch große ungefederte Massen bzw. Trägheitsmomente der primär gefederten Massen entstehen Instabilitäten und sehr hohe Kräfte zwischen Rad und Schiene, die andere Lösungen notwendig machen.The simplest type of suspension of drive units is the Tatzlagerantrieb. The DE 195 30 155 A1 describes such a solution in which the engine is supported on one side with two Tatzlagern on the wheel axle of the drive wheels and is resiliently supported on the other side on the bogie. Engine and transmission are arranged achsreitend. In this type of drive, the mass of the engine and the transmission largely unsprung on the wheelset. Disadvantage of this Tatzlageranbindung is that introduced by the unevenness of the track forces (accelerations) are transferred directly to the drive. This effect increases as the speed increases. Large unsprung masses or moments of inertia of the primarily sprung masses give rise to instabilities and very high forces between wheel and rail, which necessitate other solutions.

Insbesondere das horizontale Schwingungsverhalten macht sich bei Geschwindigkeiten ab etwa 140 km/h störend bemerkbar, wobei sich im Allgemeinen eine translatorische Schwingung mit einer quer zum Gleis gerichteten Amplitude und eine Drehschwingung um eine senkrechte Achse zu einer Schlingerbewegung überlagern.In particular, the horizontal vibration behavior is distracting at speeds above about 140 km / h, with generally superimposed on a translational vibration with a transverse to the track amplitude and a torsional vibration about a vertical axis to a rolling motion.

Diesem Problem der Fahrstabilität bzw. der Fahrsicherheit angetriebener Schienenfahrzeuge wird auf unterschiedliche Arten begegnet.This problem of driving stability or driving safety of powered rail vehicles is encountered in different ways.

Beispielsweise wird häufig der in der Technik allgemein als Tilgung bekannte Effekt herangezogen, um Quer- und Drehschwingungen um die Hochachse des Fahrwerkes zu beeinflussen und dadurch die Stabilität des Fahrzeuges entscheidend zu verbessern. Bei der Tilgung werden Eigenfrequenzen des Drehgestells bzw. der Lokomotive durch die Schwingung einer zusätzlichen Schwingmasse überlagert und gedämpft.For example, the effect commonly known in the art as eradication is often used to affect transverse and torsional vibrations about the vertical axis of the landing gear and thereby significantly improve the stability of the vehicle. In the eradication natural frequencies of the bogie or the locomotive are superimposed and damped by the vibration of an additional vibration mass.

Dieser Effekt wird durch eine Entkoppelung der Massen des Antriebs vom übrigen Fahrwerk erzielt. Vor allem bei hohen Geschwindigkeiten ist eine Entkoppelung aus lauftechnischer Sicht (instabiles Fahrverhalten) notwendig, weshalb schwere Lokomotiv-Antriebe mit achsreitendem Getriebe bisher nur bis zu Geschwindigkeiten von 160 km/h betrieben werden.This effect is achieved by decoupling the masses of the drive from the rest of the chassis. Especially at high speeds, a decoupling from a running point of view (unstable driving behavior) is necessary, which is why heavy locomotive drives are used with achsreitendem transmission so far only up to speeds of 160 km / h.

In Lokomotiv-Drehgestellen für hohe Geschwindigkeiten bis über 300 km/h werden beispielsweise voll abgefederter Hohlwellenantriebe verwendet. Dabei werden Motor und Getriebe vom Radsatz entkoppelt und die Kraftübertragung auf den Radsatz erfolgt über eine Hohlwelle, die die gesamte Radsatzwelle umschließt. Diese Lösung ist durch ihre aufwändige Konstruktion sehr teuer und schwer.In locomotive bogies for high speeds up to over 300 km / h, for example, fully sprung hollow shaft drives are used. Here, the engine and transmission are decoupled from the wheel and the power is transmitted to the wheelset via a hollow shaft that surrounds the entire axle. This solution is very expensive and heavy due to its complex construction.

Die EP 0 444 016 B1 zeigt ein Beispiel für eine solche Lösung. Der Fahrmotor und das angeflanschte Getriebe sind dabei jeweils über lotrecht verlaufende Blattfedern im Drehgestellrahmen elastisch aufgehängt und wirken so gemeinsam als Tilger für Quer- und Drehschwingungen um die Hochachse des Drehgestells. Nachteilig an dieser Lösung sind die aufwändige Konstruktion, das große Gewicht und die hohen Kosten, verursacht durch die Notwendigkeit der Installation einer Hohlwelle.The EP 0 444 016 B1 shows an example of such a solution. The traction motor and the flanged gearbox are each suspended elastically via vertically extending leaf springs in the bogie frame and thus act together as a absorber for transverse and torsional vibrations about the vertical axis of the bogie. Disadvantages of this solution are the complicated construction, the great weight and the high costs caused by the necessity of installing a hollow shaft.

Ein Drehgestell nach dem Oberbegriff des Anspruchs 1 ist aus der EP 0 589 866 B1 bekannt. Allerdings ist dabei das Getriebe direkt an den Fahrmotor angeflanscht und die Motor-Getriebeeinheit mittels federnder Elemente im Drehgestell aufgehängt. Neben dem hohen Gewicht sind auch hier die aufwändige Konstruktion und die hohen Kosten dieser Lösung nachteilig.
Weiterhin ist die CH 331 740 A bekannt, in welcher ein Fahrwerk für ein Schienenfahrzeug offenbart ist, bei welchem ein Antriebsmotor und ein Getriebe federnd auf einem Fahrwerksrahmen gelagert sind. Das Getriebe ist über eine Stütze mit einem Querträger des Fahrwerksrahmens verbunden, wodurch neben Motorlagerstellen auch eine Getriebelagerstelle auf dem Fahrwerksrahmen vorgesehen sein muss und somit ein erhöhter Herstellungsaufwand zu erwarten ist.
Die Aufgabe der Erfindung lag daher darin, ein Triebdrehgestell mit einem achsreitenden Getriebe zu konstruieren, das mit Geschwindigkeiten von mehr als 160 km/h betrieben werden kann und kostengünstig in der Herstellung ist.A bogie according to the preamble of claim 1 is known from EP 0 589 866 B1 known. However, while the gearbox is flanged directly to the traction motor and the motor-gear unit suspended by means of resilient elements in the bogie. In addition to the high weight, the complex design and the high cost of this solution are disadvantageous here.
Furthermore, the CH 331 740 A known in which a chassis for a rail vehicle is disclosed in which a drive motor and a transmission are resiliently mounted on a chassis frame. The transmission is connected via a support with a cross member of the chassis frame, which in addition to engine bearings and a gear bearing point must be provided on the chassis frame and thus an increased production cost is expected.
The object of the invention was therefore to construct a drive bogie with an off-going transmission, which can be operated at speeds of more than 160 km / h and is inexpensive to manufacture.

Diese Aufgabe wird durch ein Drehgestell nach Anspruch 1 gelöst.This object is achieved by a bogie according to claim 1.

Es ist ein Verdienst der Erfindung, dass ein Drehgestell geschaffen wird, in dem die Antriebseinheit derart angeordnet ist, dass sowohl Schwingungen quer zur Fahrtrichtung des Schienenfahrzeugs als auch Drehschwingungen um die Hochachse des Drehgestells deutlich verringert werden. Durch die querelastische Aufhängung der Motoreinheit fungiert diese als Tilger.
Die Kupplung ermöglicht die Entkoppelung von Motoreinheit und achsreitendem Getriebe, was sich als günstig erweist, da es zwischen der pendelnden Motoreinheit und dem Getriebe zu Relativbewegungen kommt. Die Kupplung überträgt weiters das Drehmoment von der Motoreinheit auf das Getriebe bzw. auf die Radsatzwelle. Die Kupplung ist dabei im Anschluss an die Motorwelle angeordnet.
Dadurch dass das Getriebe über eine Drehmomentstütze mit der Motoreinheit verbunden ist, wird einerseits ein
Anbindungspunkt am Fahrgestellrahmen eingespart, andererseits werden die Relativbewegung zwischen Motoreinheit und Kupplung und daher auch die Kupplungswege beim Einfedern des Fahrzeugs während des Betriebs reduziert. Dank dieser Lösung ist es möglich, mit hohen Massen hohe Geschwindigkeiten zu fahren, was bis dahin mit vergleichbaren Drehgestellen bzw. Antriebssystemen mit achsreitendem Getriebe nicht möglich war.It is a merit of the invention that a bogie is provided in which the drive unit is arranged such that both vibrations transverse to the direction of travel of the rail vehicle and torsional vibrations about the vertical axis of the bogie are significantly reduced. By the Transversely elastic suspension of the motor unit acts as a absorber.
The clutch allows the decoupling of motor unit and axle-going gearbox, which proves to be favorable, since there is relative movement between the oscillating motor unit and the gearbox. The clutch also transfers the torque from the engine unit to the transmission or to the wheelset shaft. The coupling is arranged following the motor shaft.
The fact that the transmission is connected via a torque arm to the motor unit, on the one hand
Connection point saved on the chassis frame, on the other hand, the relative movement between the engine unit and clutch and therefore the clutch travel when the vehicle is compressed during operation reduced. Thanks to this solution, it is possible to drive high speeds with high masses, which was previously not possible with comparable bogies or drive systems with a raging gearbox.

Die querelastische Aufhängung der Motoreinheit wird vorteilhafterweise mittels zweier pendelartiger Verbindungsstücke (115, 116) realisiert, mit denen die Motoreinheit (106) an den zwei Befestigungspunkten (110, 111) am Kopfträger (112) des Drehgestellrahmens (102) aufgehängt ist.The transverse elastic suspension of the motor unit is advantageously realized by means of two pendulum-like connecting pieces (115, 116), with which the motor unit (106) at the two attachment points (110, 111) on the head support (112) of the bogie frame (102) is suspended.

Die pendelartigen Verbindungsstücke weisen dabei in ihren Endbereichen Lager mit einer gewissen Torsionssteifigkeit auf, die im begrenzten Maß Bewegungen in alle Raumrichtungen zulassen. Grundsätzlich sind verschiedene Ausführungsformen der pendelartigen Verbindungsstücke denkbar, beispielsweise könnten sie auch als Blattfedern realisiert werden.The pendulum-type connecting pieces have bearings with a certain torsional rigidity in their end regions, which allow movements in all spatial directions to a limited extent. In principle, various embodiments of the pendulum-type connecting pieces are conceivable, for example, they could also be realized as leaf springs.

Eine besonders günstige Wirkung der Getriebe-Drehmomentstütze lässt sich erzielen, wenn der Punkt, an dem die Getriebe-Drehmomentstütze (113) mit der Motoreinheit (106) verbunden ist, so nahe wie möglich an der Kupplung (114) angeordnet ist. Die Kupplung ist dabei im Anschluss an die Motorwelle angeordnet. Unter so nahe wie möglich ist hier eine Anordnung zu verstehen, bei der die Getriebe-Drehmomentstütze so nahe an der Kupplung befestigt ist, wie innerhalb der konstruktiven Beschränkungen möglich ist, sodass eine ordnungsgemäße Funktion der Kupplung noch gewährleistet ist. Die Idealposition der Getriebe-Drehmomentstütze liegt in Fahrzeug-Längsrichtung genau in Höhe der Motorwelle. Genau genommen ist also der Punkt, über den die Getriebe-Drehmomentstütze am Gehäuse der Motoreinheit befestigt ist, so nahe als möglich an der Stelle anzuordnen, an der die Motorwelle aus dem Gehäuse der Motoreinheit heraustritt. Durch eine solche Anordnung der Getriebe-Drehmomentstütze wird die Relativbewegung zwischen Kupplung und Motoreinheit beim Einfedern des Schienenfahrzeugs während der Fahrt auf ein Minimum reduziert, was sich schonend auf die einzelnen Komponenten der Antriebseinheit auswirkt.A particularly beneficial effect of the transmission torque arm can be achieved when the point at which the transmission torque arm (113) is connected to the motor unit (106) is positioned as close as possible to the clutch (114) is. The coupling is arranged following the motor shaft. Under as close as possible here is an arrangement to understand in which the transmission torque arm is mounted as close to the clutch, as is possible within the design constraints, so that a proper function of the clutch is still guaranteed. The ideal position of the transmission torque arm lies in the vehicle longitudinal direction exactly at the height of the motor shaft. Strictly speaking, therefore, the point at which the transmission torque arm is attached to the housing of the motor unit is to be located as close as possible to the point where the motor shaft emerges from the housing of the motor unit. By such an arrangement of the transmission torque arm, the relative movement between the clutch and motor unit during compression of the rail vehicle while driving is reduced to a minimum, which has a gentle effect on the individual components of the drive unit.

Die Getriebe-Drehmomentstütze (113) ist vorteilhafterweise als pendelartiges Verbindungsstück ausgestaltet. Ähnlich wie bei den Verbindungsstücken, mit denen die Motoreinheit am Kopfträger des Drehgestellrahmens aufgehängt ist, besteht das pendelartige Verbindungsstück hier aus einer Art Achse, die an ihren Enden Lager aufweist, die eine Bewegung der Getriebe-Drehmomentstütze zulassen.The transmission torque arm (113) is advantageously designed as a pendulum-like connector. Similar to the connectors with which the motor unit is suspended on the head carrier of the bogie frame, the pendulum-like connector here consists of a kind of axle having at its ends bearings that allow movement of the transmission torque arm.

Eine vorteilhafte Aufhängung der Motoreinheit im erfindungsgemäßen Drehgestell lässt sich realisieren, wenn die Aufhängung der Motoreinheit (106) am Kopfträger (112) des Drehgestellrahmens (102) mittels zumindest einem Tragarm (117, 118) erfolgt, wobei die Verbindung zwischen Tragarm (117, 118) und den Befestigungspunkten (110, 111) über zumindest einen auswechselbaren Tragarmadapter (119) erfolgt.An advantageous suspension of the motor unit in the bogie according to the invention can be realized when the suspension of the motor unit (106) on the head support (112) of the bogie frame (102) by means of at least one support arm (117, 118), wherein the connection between the support arm (117, 118 ) and the attachment points (110, 111) via at least one interchangeable Tragarmadapter (119).

Der Tragarm ist dabei im Wesentlichen horizontal angeordnet. Neben der als einfachste Ausführungsform möglichen Variante mit genau einem Tragarm werden bevorzugt zwei Tragarme verwendet, wodurch sich eine einfachere Verbindung mit den Befestigungspunkten bzw. den Tragarmadaptern realisieren lässt. Die Tragarmadapter sind mit den Tragarmen beispielsweise verschraubt oder verschweißt.The support arm is arranged substantially horizontally. In addition to the possible as the simplest embodiment variant with exactly one arm preferably two support arms are used, resulting in a simpler connection with the Can realize attachment points or the Tragarmadaptern. The Tragarmadapter are bolted or welded to the support arms, for example.

Günstigerweise sind zwei Paare von Tragarmen (117, 118, 122) vorgesehen, die nebeneinander angeordnet sind und jeweils aus einem oberen und einem unteren Tragarm bestehen.Conveniently, two pairs of support arms (117, 118, 122) are provided, which are arranged side by side and each consist of an upper and a lower support arm.

Dadurch ist eine besondere Stabilität der Konstruktion gegeben, weiters lässt sich die Verbindung zwischen Tragarmen und Tragarmadaptern stabiler gestalten.As a result, a special stability of the construction is given, furthermore, the connection between support arms and Tragarmadaptern can make more stable.

Dadurch, dass die Verbindung zwischen den Tragarmadaptern und den Befestigungspunkten am Drehgestellrahmen über die Tragarmadapter erfolgt, lässt sich eine modulare Bauweise realisieren, mit der der Drehgestellrahmen auf den jeweils geplanten Anwendungsbereich zugeschnitten werden kann.The fact that the connection between the Tragarmadaptern and the attachment points on the bogie frame via the Tragarmadapter, a modular design can be realized with which the bogie frame can be tailored to the intended application area.

In einer Variante der Erfindung sind die Tragarmadapter (119) beispielsweise derart ausgestaltet, dass sie direkt mit den Befestigungspunkten (110, 111) am Kopfträger (112) des Drehgestellrahmens (102) starr verbunden sind.In a variant of the invention, the support arm adapters (119) are designed, for example, such that they are rigidly connected directly to the attachment points (110, 111) on the head support (112) of the bogie frame (102).

Eine solche Ausführung kann beispielsweise für Schienenfahrzeuge verwendet werden, die eine maximale Geschwindigkeit von 160 km/h erreichen. Durch eine solche Ausführung könnten beispielsweise Anschlagmittel und Dämpfungselemente eingespart werden, da es durch die starre Verbindung zu keinen Schwingungsbewegungen der Motoreinheit kommt, weiters sind keine pendelartigen Verbindungsstücke notwendig, wodurch sich die Kosten eines solchen Drehgestells deutlich reduzieren.Such an embodiment can be used for example for rail vehicles that reach a maximum speed of 160 km / h. By such an embodiment, for example, stop means and damping elements could be saved, as it comes through the rigid connection to no vibration movements of the motor unit, further no pendulum-type connectors are necessary, thereby significantly reducing the cost of such a bogie.

In einer weiteren Variante sind die Tragarmadapter (119) derart ausgestaltet, dass die Verbindung von einem Tragarmadapter (119) und dem Befestigungspunkt (110, 111) am Kopfträger (112) des Drehgestellrahmens (102) mit einem pendelartigen Verbindungsstück (115, 116) erfolgt.In another variant, the Tragarmadapter (119) are designed such that the connection of a Tragarmadapter (119) and the attachment point (110, 111) on the head support (112) of the bogie frame (102) with a pendulum-like connector (115, 116) ,

Mit dieser pendelnden Aufhängung, wie sie durch die Verwendung von pendelartigen Verbindungsstücken erfolgt, lassen sich höhere Massen und Geschwindigkeiten für Schienenfahrzeuge mit dem erfindungsgemäßen Drehgestell realisieren. Geschwindigkeiten über 160 km/h sind so möglich.With this pendulum suspension, as is done by the use of pendulum-like connectors, higher masses and speeds for rail vehicles can be realized with the bogie according to the invention. Speeds over 160 km / h are possible.

Quer- und Drehschwingungen um die Hochachse eines erfindungsgemäßen Drehgestells lassen sich weiter reduzieren, wenn zwischen der Antriebseinheit und dem Drehgestellrahmen (102) in an sich bekannter Weise ein in Querrichtung zur Längsachse des Drehgestells (101) wirkendes Dämpfungselement (120) vorgesehen ist.Transverse and torsional vibrations about the vertical axis of a bogie according to the invention can be further reduced if between the drive unit and the bogie frame (102) in a conventional manner a transversely to the longitudinal axis of the bogie (101) acting damping element (120) is provided.

Bei diesem Dämpfungselement kann es sich beispielsweise um einen pneumatischen oder hydraulischen Dämpfer handeln, auch andere Ausführungsformen unter Verwendung von Gummi- oder Elastomer-Elementen sind denkbar. Durch die Anordnung eines solchen Dämpfungselementes ist durch die verbesserte Abstimmungscharakteristik der Antriebs- bzw. Motoreinheit gegenüber dem Drehgestellrahmen eine Optimierung der Tilgewirkung möglich.This damping element may be, for example, a pneumatic or hydraulic damper, other embodiments using rubber or elastomeric elements are conceivable. By the arrangement of such a damping element, an optimization of the absorption effect is possible by the improved tuning characteristic of the drive or motor unit relative to the bogie frame.

In einer weiteren Ausführungsform der Erfindung ist am Kopfträger (112) zumindest eine, die Bewegung der Motoreinheit (106) in Querrichtung zur Längsachse des Drehgestellrahmens (102) begrenzende Anschlagvorrichtung (121) angeordnet.In a further embodiment of the invention, at least one stop device (121) delimiting the movement of the motor unit (106) in the transverse direction to the longitudinal axis of the bogie frame (102) is arranged on the head carrier (112).

Dadurch kann die Amplitude der Pendelbewegung der Motoreinheit innerhalb von vordefinierten Grenzen gehalten werden, wodurch eine Beschädigung des Drehgestells durch die Motor- bzw. Antriebseinheit verhindert wird.

Die Figuren zeigen jeweils Ausschnitte eines Drehgestells 101, in welchem zwei Radsätze in üblicher Weise gelagert sind, und durch je eine Motoreinheit 106 angetrieben werden. Fig. 1 zeigt die rechte Seite eines Drehgestellrahmens 102 eines erfindungsgemäßen Drehgestells 101, wobei auf der linken Seite der Fig. 1 der Querträger 109 und auf der rechten Seite der Kopfträger 112 dargestellt sind. Weiters ist ein Triebradsatz, bestehend aus einer Radsatzwelle 103 und zwei Rädern 104, 105 dargestellt. Der Radsatz ist begrenzt beweglich gegen den Drehgestellrahmen 102.The figures each show sections of a bogie 101, in which two wheelsets are mounted in a conventional manner, and are driven by a respective motor unit 106. Fig. 1 shows the right side of a bogie frame 102 of a bogie 101 according to the invention, wherein on the left side of Fig. 1 the cross member 109 and on the right side of the head support 112 are shown. Furthermore, a drive wheel set consisting of a wheelset shaft 103 and two wheels 104, 105 is shown. The wheelset is limitedly movable against the bogie frame 102.

Fig. 1 zeigt außerdem eine Antriebseinheit, bestehend aus einer Motoreinheit 106, einem Getriebe 107 und einer Kupplung 114. Die Bestandteile der Kupplung 114, beispielsweise zwei Kupplungssterne zur Übertragung des Drehmoments von der Motoreinheit 106 auf die Radsatzwelle 103, sind direkt nach der Motorwelle 123 angeordnet.
Das Getriebe 107 ist achsreitend auf der Radsatzwelle 103 montiert, wobei es um die Radsatzwelle 103 beweglich, aber unverschiebbar entlang der Welle gelagert ist.
Die Antriebseinheit ist an drei Stellen im Drehgestellrahmen 102 aufgehängt, nämlich im Hauptdrehpunkt 108 am Querträger 109 und in zwei Befestigungspunkten 110, 111, die in Fig. 1 nicht erkennbar sind, da sie vom Kopfträger 112 verdeckt werden. Fig. 1 also shows a drive unit consisting of a motor unit 106, a gear 107 and a clutch 114. The components of the clutch 114, for example two Clutch stars for transmitting the torque from the motor unit 106 to the wheelset shaft 103, are arranged directly after the motor shaft 123.
The gear 107 is mounted axially on the wheelset shaft 103, being mounted movably but immovably along the shaft about the wheelset shaft 103.
The drive unit is suspended in three places in the bogie frame 102, namely at the main pivot point 108 on the cross member 109 and in two attachment points 110, 111, in Fig. 1 are not recognizable because they are obscured by the head carrier 112.

Die Verbindung zwischen Motoreinheit 106 und den Befestigungspunkten 110, 111 am Kopfträger 112 des Drehgestellrahmens 102 erfolgt mittels Tragarmen 117, 118, an denen auf Seiten des Kopfträgers 112 jeweils Tragarmadapter 119 (Fig. 4) angeordnet sind, die aber in Fig. 1 ebenfalls durch den Kopfträger 112 verdeckt sind. In der vorliegenden Ausführungsform der Erfindung sind zwei Paare von Tragarmen 117, 118 vorgesehen, die nebeneinander angeordnet sind. Aus Fig. 4 ist erkenntlich, dass jeweils ein oberer 117 und ein unterer Tragarm 122 vorgesehen sind. Beide Tragarme sind hier mit dem Tragarmadapter 119 verbunden. Grundsätzlich wäre auch eine Aufhängung mit nur einem Tragarm denkbar, auch Varianten mit mehr als vier Tragarmen sind selbstverständlich möglich. Durch das Vorsehen von zwei Paaren von Tragarmen, die jeweils aus einem oberen Tragarm 117, 118 und einem unteren Tragarm 122 bestehen und mittels einem Tragarmadapter 119 mit dem Drehgestellrahmen 102 verbunden sind, lassen sich modulare Lösungen für die Aufhängung der Motoreinheit 106 im Drehgestellrahmen 102 realisieren. Außerdem wird durch diese Lösung die Baustabilität der Aufhängung verbessert.The connection between the motor unit 106 and the attachment points 110, 111 on the head carrier 112 of the bogie frame 102 by means of support arms 117, 118, where on the side of the head support 112 each support arm adapter 119 (FIGS. Fig. 4 ) are arranged, but in Fig. 1 are also hidden by the head carrier 112. In the present embodiment of the invention, two pairs of support arms 117, 118 are provided, which are arranged side by side. Out Fig. 4 is recognizable that in each case an upper 117 and a lower arm 122 are provided. Both support arms are connected here to the Tragarmadapter 119. In principle, a suspension with only one support arm would be conceivable, even variants with more than four support arms are of course possible. By providing two pairs of support arms, each consisting of an upper support arm 117, 118 and a lower support arm 122 and connected by a Tragarmadapter 119 with the bogie frame 102, modular solutions for the suspension of the motor unit 106 in the bogie frame 102 can be realized , In addition, this solution improves the structural stability of the suspension.

Beispielsweise kann der Tragarmadapter 119 derart realisiert sein, dass durch ein Vertauschen der oberen 117, 118 und unteren 122 Tragarme eine starre, nicht pendelnde Verbindung mit dem Drehgestellrahmen 102 bzw. dem Kopfträger ermöglicht wird. So könnten mit den gleichen Bauteilen sowohl eine starre als auch eine pendelnde Aufhängung der Motoreinheit 106 realisiert werden.
Außerdem ist es durch diesen modularen Aufbau möglich, die Radsatzwelle 103 auszubauen während die Motoreinheit 106 im Drehgestellrahmen 102 montiert bleibt. Das das möglich ist, ist sehr schön aus Fig. 4 erkennbar: Durch Ausbauen der unteren Tragarme 122 kann das Ausachsen durchgeführt werden, ohne dass weitere Umbauarbeiten am Drehgestell 101 vorgenommen werden müssen.For example, the support arm adapter 119 may be realized such that a swapping of the upper 117, 118 and lower 122 support arms a rigid, non-oscillating connection with the bogie frame 102 and the head support is made possible. So could with the same components both a rigid as well as a swinging suspension of the motor unit 106 can be realized.
In addition, this modular design makes it possible to remove the wheel set shaft 103 while the motor unit 106 remains mounted in the bogie frame 102. That that is possible is very nice Fig. 4 recognizable: By removing the lower support arms 122, the Ausachsen can be performed without further reconstruction work on the bogie 101 must be made.

Fig. 5a zeigt die Tragarme 117, 122 im Detail - in dieser Ausführung erfolgt die Verbindung der Tragarme 117, 122 mit dem Drehgestellrahmen 102 mittels einem pendelartigen Verbindungsstück 115, das über den Tragarmadapter 119 mit den Tragarmen 117, 122 verbunden ist. Die Ausführungsform, bei der eine starre Verbindung der Tragarme 117, 122, also der Motoreinheit 106, mit dem Drehgestellrahmen 102 vorliegt, ist in Fig. 5b dargestellt. Eine solche Variante erlaubt die Einsparung von Anschlagsvorrichtungen, Querdämpfern und ähnlichem. Aus den Fign. 5a und 5b ist ersichtlich, dass im Prinzip die Tragarme zur Realisierung der beiden möglichen Varianten einfach ausgetauscht werden müssen - der obere Tragarm ist dann jeweils der untere Tragarm, bzw. vice versa. Fig. 2 zeigt einen Schnitt des Drehgestells 101 aus Fig. 1 entlang der Linie A-A. Hier ist erkennbar, dass zwischen den Tragarmadaptern 119 und den Befestigungspunkten 110, 111 pendelartige Verbindungstücke 115, 116 angeordnet sind, die eine schwenkbare Lagerung der Antriebs- bzw. Motoreinheit 106 im Drehgestellrahmen 102 erlauben. Diese pendelartigen Verbindungsstücke 115, 116 sind auch in den Fign. 3 und 4 deutlich erkennbar. Die Befestigung der Verbindungsstücke 115, 116 an den Tragarmadaptern 119 erfolgt über ein Lager mit einer gewissen Torsionssteifigkeit, das ein Pendeln der Motoreinheit 106 und so ein erfindungsgemäßes Funktionieren als Tilgermasse zulässt. Fig. 5a shows the support arms 117, 122 in detail - in this embodiment, the connection of the support arms 117, 122 takes place with the bogie frame 102 by means of a pendulum-like connector 115 which is connected via the Tragarmadapter 119 with the support arms 117, 122. The embodiment in which there is a rigid connection of the support arms 117, 122, that is, the motor unit 106, to the bogie frame 102, is shown in FIG Fig. 5b shown. Such a variant allows the saving of stop devices, transverse dampers and the like. From the FIGS. 5a and 5b It can be seen that, in principle, the support arms for the realization of the two possible variants must be easily replaced - the upper arm is then the lower arm, or vice versa. Fig. 2 shows a section of the bogie 101 from Fig. 1 along the line AA. Here it can be seen that between the Tragarmadaptern 119 and the attachment points 110, 111 pendulum-like connecting pieces 115, 116 are arranged, which allow a pivotable mounting of the drive or motor unit 106 in the bogie frame 102. These pendulum-type connecting pieces 115, 116 are also in the FIGS. 3 and 4 clearly. The attachment of the connecting pieces 115, 116 to the Tragarmadaptern 119 via a bearing with a certain torsional stiffness, which allows a commuting of the motor unit 106 and so an inventive functioning as absorber mass.

Unter pendelartig wird hier eine Vorrichtung verstanden, die es erlaubt, durch Auslenkung aus der Ruhelage in Schwingung versetzt zu werden und um den zentralen, tiefsten Punkt des Masseschwerpunkts zu schwingen. Im vorliegenden Fall bedeutet das, dass die Motoreinheit 106, die an pendelartigen Verbindungsstücken 115, 116 im Drehgestellrahmen 102 aufgehängt ist, durch Beschleunigungen, die während der Fahrt eines Schienenfahrzeuges auftreten können, in Schwingung versetzt wird und dergestalt als Tilgermasse für das Drehgestell 101 fungiert. Diese Schwingungsbewegung wird auch durch die Lagerung im Hauptdrehpunkt 108 am Querträger 109 (sowie durch die pendelnde Aufhängung am Kopfträger)des Drehgestellrahmens 102 definiert.Under pendulum-like is understood here a device that allows it by deflection from the rest position in oscillation to be offset and swing around the central, lowest point of the center of mass. In the present case, this means that the motor unit 106, which is suspended on pendulum-type connecting pieces 115, 116 in the bogie frame 102, is set in vibration by accelerations which can occur during the travel of a rail vehicle and thus acts as a damping mass for the bogie 101. This oscillatory movement is also defined by the bearing at the main pivot point 108 on the cross member 109 (as well as by the pendulum suspension on the head carrier) of the bogie frame 102.

Die pendelartigen Verbindungsstücke 115, 116 können dabei auch als Blattfedern realisiert sein.The pendulum-like connecting pieces 115, 116 can also be realized as leaf springs.

In Fig. 3 ist erkennbar, dass weiters zwischen der Antriebseinheit und dem Drehgestellrahmen 102 zur Bedämpfung der Motorbewegung geeignete Dämpfungseinheit 120 vorgesehen ist, die in Querrichtung zur Längsachse des Drehgestells 101 eingebaut ist. Diese Dämpfungseinheit 120 ist beispielsweise hydraulisch oder pneumatisch ausgeführt, kann aber auch anders ausgestaltet sein. Auch in den Fign. 1 und 4 ist die Dämpfungseinheit 120 teilweise erkennbar.
Vorteilhaft ist auch die Anordnung der Getriebe-Drehmomentstütze 113 am Gehäuse der Motoreinheit 106. Die Getriebe-Drehmomentstütze 113 ist zwischen dem Getriebe 107 und der Motoreinheit 106 angeordnet. Die Befestigung der Getriebe-Drehmomentstütze 113 erfolgt dabei am Gehäuse der Motoreinheit 106.In Fig. 3 It can be seen that further between the drive unit and the bogie frame 102 for damping the motor movement suitable damping unit 120 is provided, which is installed in the transverse direction to the longitudinal axis of the bogie 101. This damping unit 120 is designed for example hydraulically or pneumatically, but can also be configured differently. Also in the FIGS. 1 and 4 the damping unit 120 is partially visible.
The arrangement of the gearbox torque arm 113 on the housing of the motor unit 106 is also advantageous. The gearbox torque arm 113 is arranged between the gearbox 107 and the motor unit 106. The attachment of the transmission torque arm 113 is carried out on the housing of the motor unit 106th

Um eine günstige Wirkung der Getriebe-Drehmomentstütze 113 zu erreichen, wird sie am Gehäuse der Motoreinheit 106 so nahe als möglich an der Stelle angeordnet, an der die Motorwelle 123. Die Idealposition der Getriebe-Drehmomentstütze liegt in Fahrzeug-Längsrichtung genau in Höhe der Motorwelle. Unter so nah als möglich ist hier der konstruktiv gerade noch vertretbare Abstand zu verstehen, der eine ordnungsgemäße Funktion von Getriebe 107 und Kupplung 114 erlaubt. Je geringer der Abstand ist, desto geringer ist die Relativbewegung zwischen Getriebe 107 und Motoreinheit 106 beim betriebsbedingten Einfedern des Drehgestells 101. Die Verringerung der Relativbewegungen wirkt dabei kupplungsschonend.To achieve a beneficial effect of the gearbox torque arm 113, it is placed on the housing of the motor unit 106 as close as possible to the location where the motor shaft 123. The ideal position of the gearbox torque arm lies in the vehicle longitudinal direction at the same level of the motor shaft , Under as close as possible here is the structurally just acceptable distance to understand that allows proper operation of gear 107 and clutch 114. ever the smaller the distance, the lower is the relative movement between the gear 107 and the motor unit 106 during operational compression of the bogie 101. The reduction of the relative movements acts clutch-friendly.

Die Getriebe-Drehmomentstütze 113 ist ähnlich den Aufhängungen der Motoreinheit 106 am Kopfträger 112 des Drehgestellrahmens 102 als pendelförmige Verbindung ausgestaltet.
Durch diese Momentstütze wird einerseits ein Anbindungspunkt am Drehgestellrahmen 102 eingespart, andererseits werden die Kupplungswege beim Einfedern des Fahrzeugs im Betrieb minimiert.The transmission torque arm 113 is similar to the suspensions of the motor unit 106 on the head support 112 of the bogie frame 102 configured as a pendulum-shaped connection.
By this moment support on the one hand a connection point on the bogie frame 102 is saved, on the other hand, the clutch travel during compression of the vehicle are minimized during operation.

Eine aus dem Stand der Technik bekannte Ausführungsform sieht vor, dass die Getriebe-Drehmomentstütze 113 nicht mit der Motoreinheit 106, sondern mit dem Querträger 109 des Drehgestellrahmens 102 verbunden ist. Eine solche Lösung ist in Fig. 6 dargestellt, wo der Getriebe-Drehpunkt 124 am Querträger 109 des Drehgestellrahmens 102 angeordnet ist. Es sei darauf hingewiesen, dass die Darstellung in Fig. 6 nur schematisch ist und eine tatsächliche Ausführung den realen Anforderungen entsprechend leicht verschieden ausgeführt sein wird.One known from the prior art embodiment provides that the transmission torque arm 113 is not connected to the motor unit 106, but with the cross member 109 of the bogie frame 102. Such a solution is in Fig. 6 illustrated where the transmission pivot 124 is disposed on the cross member 109 of the bogie frame 102. It should be noted that the illustration in Fig. 6 is only schematic and an actual execution will be performed slightly different according to the real requirements.

Um zu verhindern, dass die Motoreinheit 106 zu stark schwingt, ist am Drehgestellrahmen 102 eine Anschlagvorrichtung 121 angeordnet, die zu große Amplituden der schwingenden Motoreinheit 106 abfängt. So können etwaige Zerstörungen am Drehgestell 101 durch die Motoreinheit 106 verhindert werden.In order to prevent the motor unit 106 from oscillating too much, a stop device 121 is arranged on the bogie frame 102, which intercepts large amplitudes of the oscillating motor unit 106. Thus, any damage to the bogie 101 can be prevented by the motor unit 106.

Grundsätzlich ist es möglich, mit dem erfindungsgemäßen Drehgestell unterschiedliche Antriebsvarianten zu realisieren. An den drei vorgesehenen Befestigungspunkten kann beispielsweise auch ein fest am Rahmen montierter Ritzel-Hohlwellenantrieb aufgehängt sein, weiters sind der Einbau eines elastischen Ritzel-Hohlwellenantriebs wie eben vorgestellt, aber auch die Montage eines konventionellen Hohlwellenantriebs mit elastischer Fixierung für hohe Geschwindigkeiten möglich.In principle, it is possible to realize different drive variants with the bogie according to the invention. At the three provided attachment points, for example, a fixed mounted on the frame pinion hollow shaft drive can be suspended, further are the Installation of a flexible hollow shaft drive as just presented, but also the installation of a conventional hollow shaft drive with elastic fixation for high speeds possible.
