Es ist allgemein bekannt, dass Schienenanlagen ein entlang einer Schienenstrecke bewegbares Schienenfahrzeug umfassen.It is well known that rail systems comprise a rail vehicle movable along a rail track.

Aus der EP 2 172 381 A1 ist eine Elektrohängebahn bekannt. Dieses Dokument beschreibt eine Schienenanlage, umfassend ein entlang einer Schienenstrecke bewegbares Schienenfahrzeug ,wobei die Schienenstrecke aus Schienenteilen zusammengesetzt ist, und wobei das Schienenfahrzeug einen Elektromotor aufweist, mittels dessen das Schienenfahrzeug antreibbar ist, also in Schienenrichtung bewegbar entlang der Schienenstrecke. From the EP 2 172 381 A1 is an electric monorail system known. This document describes a rail system, comprising a rail vehicle movable along a rail track, wherein the rail track is composed of rail parts, and wherein the rail vehicle has an electric motor, by means of which the rail vehicle is driven, so in the rail direction movable along the rail track.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Schienenfahrzeug mit möglichst geringer Masse weiterzubilden.The invention is therefore based on the object of developing a rail vehicle with the lowest possible mass.

Erfindungsgemäß wird die Aufgabe bei der Schienenanlage nach den in Anspruch 1 angegebenen Merkmalen gelöst.According to the invention the object is achieved in the rail system according to the features indicated in claim 1.

Wichtige Merkmale der Erfindung bei der Schienenanlage, umfassend ein entlang einer Schienenstrecke bewegbares Schienenfahrzeug,
wobei die Schienenstrecke aus Schienenteilen zusammengesetzt ist, sind, dass das Schienenfahrzeug einen Elektromotor aufweist, mittels dessen das Schienenfahrzeug antreibbar ist, also in Schienenrichtung bewegbar entlang der Schienenstrecke,
wobei eine oder mehrere Polradscheibenanordnungen stationär, also mit der Schienenstrecke verbunden, angeordnet ist oder sind,
wobei das Schienenfahrzeug ein Reaktionsteil aufweist, welches mit den Polradscheibenanordnungen in Wirkverbindung bringbar ist, zur Erzeugung einer von Wirbelströmen erzeugten Reaktionskraft .Important features of the invention in the rail system, comprising a rail vehicle movable along a rail track,
wherein the rail track is composed of rail parts, are that the rail vehicle has an electric motor by means of which the rail vehicle is driven, so in the rail direction movable along the rail track,
wherein one or more Polradscheibenanordnungen stationary, ie connected to the rail track, is or are,
wherein the rail vehicle has a reaction part, which is operatively engageable with the Polradscheibenanordnungen, for generating a reaction force generated by eddy currents.

Von Vorteil ist dabei, dass ein die Hangabtriebskraft überwindender Zusatzkraftbetrag von der Polradscheibenanordnung erzeugbar ist im jeweiligen Steigungsstreckenabschnitt. Somit ist der Antriebsmotor des Schienenfahrzeugs kleiner dimensionierbar und das Schienenfahrzeug mit weniger Masse ausführbar.The advantage here is that a the Hangabtriebskraft overcoming additional amount of force of the Polradscheibenanordnung can be generated in the respective pitch section. Thus, the drive motor of the rail vehicle is smaller dimensionable and the rail vehicle executable with less mass.

Bei einer vorteilhaften Ausgestaltung weist das Schienenfahrzeug einen Antrieb, umfassend ein von dem Elektromotor 5, direkt oder über ein Getriebe, angetriebenes mit der Schienenstrecke zusammenwirkendes Zahnrad oder Reibrad, auf, wobei der vom Antrieb maximal erzeugbare Vorschubskraftbetrag kleiner ist als ein in einem Teilbereich der Schienenstrecke auftretender Hangabtriebskraftbetrag. Von Vorteil ist dabei, dass ein Reibradantrieb vorsehbar ist, der allerdings nur für Strecken ohne Steigung ausgelegt werden muss. Denn in Steigungsstreckenabschnitten ist jeweils zumindest eine Polradscheibenanordnung als Zusatzantrieb installierbar.In an advantageous embodiment, the rail vehicle has a drive, comprising a gear or friction wheel, driven by the electric motor 5, directly or via a gear, cooperating with the rail track, wherein the maximum amount of feed force that can be generated by the drive is smaller than one in a partial area of the rail track occurring downgrade force amount. The advantage here is that a Reibradantrieb is providable, but must be designed only for routes without incline. Because in pitch sections each at least one Polradscheibenanordnung can be installed as an additional drive.

Bei einer vorteilhaften Ausgestaltung ist die Polradscheibenanordnung entlang eines Steigungsstreckenabschnitt angeordnet, zur Erzeugung von zusätzlicher Vorschubskraft zur Überwindung einer Hangabtriebskraft. Von Vorteil ist dabei, dass die Masse des Antriebs des Schienenfahrzeugs gering wählbar ist und trotzdem steile Steigungsstreckenabschnitte in der Anlage durchfahrbar sind. Ebenso ist auch die notwendige Leistungszufuhr ans Schienenfahrzeug gering und daher die Schleifleitungsversorgung entsprechend klein auslegbar.In an advantageous embodiment, the Polradscheibenanordnung is arranged along a pitch section, for generating additional feed force to overcome a slope force. The advantage here is that the mass of the drive of the rail vehicle is low selectable and yet steep slope sections are traversable in the system. Likewise, the necessary power supply to the rail vehicle is low and therefore the contact line supply correspondingly small interpretable.

Bei einer vorteilhaften Ausgestaltung weist jede Polradscheibenanordnung von einem Motor angetriebene Polradscheiben auf, zwischen denen zumindest ein jeweiliger Spaltbereich vorhanden ist, durch welchen ein Abschnitt des Reaktionsteils hindurchbewegbar ist.. Von Vorteil ist dabei, dass der eintauchende Abschnitt des Reaktionsteils fast bis zum Außendurchmesser der die Polradscheiben antreibenden Welle eintauchen darf. Somit ist eine hohe Zusatz-Antriebskraft erreichbar. Dabei ist das Reaktionsteil aus metallischem Material ausführbar. Mittels der Formgebung des Reaktionsteils ist der beim anfänglichen Eintauchen in den Spaltbereich Kraftstoß verringerbar. Wenn also der eintauchende schenkelabschnitt des Reaktionsteils mit einem spitzwinkligen Endbereich ausgeführt ist und mit diesem in den Spaltbereich eintaucht, ist ein sehr sanftes Bewegen des Schienenfahrzeugs ermöglicht.In an advantageous embodiment, each Polradscheibenanordnung of a motor driven Polradscheiben on, between which at least one respective gap region is present, through which a portion of the reaction member is hindurchbewegbar .. It is advantageous that the immersing portion of the reaction part almost to the outer diameter of the Polradscheiben driving shaft may dip. Thus, a high additional driving force is achievable. In this case, the reaction part of metallic material is executable. By means of the shaping of the reaction part of the initial immersion in the gap region impulse is reduced. So if the dive limb portion of the reaction part is designed with an acute-angled end portion and immersed with this in the gap region, a very smooth movement of the rail vehicle is possible.

Bei einer vorteilhaften Ausgestaltung weist jede Polradscheibenanordnung von einem Motor angetriebene Polradscheiben auf, wobei zwischen jeweils zwei benachbarten Polradscheiben jeweils ein Spaltbereich vorhanden ist, durch welchen ein jeweiliger Abschnitt des Reaktionsteils durchfahrbar ist. Von Vorteil ist dabei, dass mehrere Abschnitte des Reaktionsteils von mehreren Polradscheiben gleichzeitig antreibbar sind und somit hohe Kräfte erzeugbar sind.In an advantageous embodiment, each Polradscheibenanordnung of a motor driven Polradscheiben, wherein between each two adjacent Polradscheiben each have a gap region is present, through which a respective portion of the reaction part is durchfahrbar. The advantage here is that several sections of the reaction part of several Polradscheiben are simultaneously driven and thus high forces can be generated.

Bei einer vorteilhaften Ausgestaltung weist das Reaktionsteil Schenkelabschnitte auf, wobei jeder Schenkelabschnitt in einen zwischen zwei Polradscheiben einer jeweiligen stationär angeordneten Polradscheibenanordnung Spaltbereich eintauchbar ist und durch diesen Spaltbereich in Schienenrichtung hindurchbewegbar ist. Von Vorteil ist dabei, dass mehrere Schenkelabschnitte gleichzeitig Eintauchen zwischen die Polradscheiben. Durch beidseitiges Bestücken derselben mit Dauermagneten ist eine sehr kompakte Anordnung erreichbar.In an advantageous embodiment, the reaction part has leg sections, wherein each leg section can be inserted into a gap region between two pole wheel disks of a respective stationarily arranged rotor disk arrangement and can be moved through this gap region in the rail direction. The advantage here is that several leg sections simultaneously immersion between the Polradscheiben. By equipping them with permanent magnets on both sides, a very compact arrangement can be achieved.

Bei einer vorteilhaften Ausgestaltung ist das Reaktionsteil am Gestänge des Schienenfahrzeugs befestigt, wobei das Gestänge über am Gestänge gelagerte Räder auf der Schienenstrecke oder auf Schienenteilen der Schienenstrecke verfahrbar ist. Von Vorteil ist dabei, dass die vom Zusatzantrieb erzeugte Kraft direkt auf das starr ausgebildete Gestänge des Schienenfahrzeugs geleitet und zum Vortrieb desselben nutzbar ist.In an advantageous embodiment, the reaction part is attached to the linkage of the rail vehicle, wherein the linkage is movable via mounted on the linkage wheels on the rail track or on rail parts of the rail track. The advantage here is that the force generated by the additional drive is directed directly to the rigidly formed linkage of the rail vehicle and used for propulsion thereof.

Bei einer vorteilhaften Ausgestaltung ist die Schenkelabschnitte des Reaktionsteils und/oder die Spaltbereiche regelmäßig voneinander beabstandet. Von Vorteil ist dabei, dass die Schenkelabschnitte des Reaktionsteils ebenso beabstandbar sind. Außerdem ist eine modulare Ausführung in einfacher Weise gestaltbar, bei der mehrere Polradscheiben axial hintereinander stapelbar sind.In an advantageous embodiment, the leg portions of the reaction part and / or the gap regions are regularly spaced from each other. The advantage here is that the leg portions of the reaction part are equally spaced. In addition, a modular design can be designed in a simple manner, in which a plurality of Polradscheiben are axially stacked one behind the other.

Bei einer vorteilhaften Ausgestaltung ist der Abstand zwischen in Schienenrichtung nacheinander folgenden Polradscheibenanordnungen kleiner als die Ausdehnung des Reaktionsteils in Schienenrichtung. Von Vorteil ist dabei, dass in einem Steigungsstreckenabschnitt stets mehr als nur eine einzige Polradscheibenanordnung wirksam ist.In an advantageous embodiment, the distance between successive following in the rail direction Polradscheibenanordnungen is smaller than the extension of the reaction part in the rail direction. The advantage here is that in one Gradient section always more than a single Polradscheibenanordnung is effective.

Bei einer vorteilhaften Ausgestaltung sind im Steigungsstreckenabschnitt zumindest stets zwei in Schienenrichtung voneinander beabstandete Polradscheibenanordnungen in Wirkverbindung mit dem Reaktionsteil. Von Vorteil ist dabei, dass bei langen Steigungsstreckenabschnitten ein sanfter Antriebskraftverlauf erreichbar ist.In an advantageous refinement, at least two pole wheel disk arrangements which are spaced apart from one another in the rail direction in the ascending path section are at least always in operative connection with the reaction part. The advantage here is that at long pitch sections a gentle drive power curve is achievable.

Für den Fachmann ergeben sich weitere sinnvolle Kombinationsmöglichkeiten von Ansprüchen und/oder einzelnen Anspruchsmerkmalen und/oder Merkmalen der Beschreibung und/oder der Figuren, insbesondere aus der Aufgabenstellung und/oder der sich durch Vergleich mit dem Stand der Technik stellenden Aufgabe.Further advantages emerge from the subclaims. The invention is not limited to the combination of features of the claims. For the skilled person, further meaningful combination options of claims and / or individual claim features and / or features of the description and / or figures, in particular from the task and / or the task posing by comparison with the prior art arise.

Die Erfindung wird nun anhand von Abbildungen näher erläutert:
In der Figur 1 ist ein schematischer Aufbau einer erfindungsgemäßen Schienenanlage mit Schienenfahrzeug gezeigt, wobei das Reaktionsteil 20 des Schienenfahrzeug nicht dargestellt ist.The invention will now be explained in more detail with reference to figures:
In the FIG. 1 is a schematic structure of a rail system according to the invention shown with rail vehicle, wherein the reaction part 20 of the rail vehicle is not shown.

In der Figur 2 ist ein Querschnitt gezeigt, wobei das Reaktionsteil 20 teilweise dargestellt ist.In the FIG. 2 a cross section is shown, wherein the reaction part 20 is partially shown.

In der Figur 3 ist eine zugehörige Schrägansicht gezeigt.In the FIG. 3 an associated oblique view is shown.

In der Figur 4 ist ein vergrößerter Ausschnitt der Figur 3 gezeigt.In the FIG. 4 is an enlarged section of the FIG. 3 shown.

Die Schienenanlage ist beispielsweise eine Einschienenhängebahn.The rail system is for example a monorail railway.

Dabei weist das Schienenfahrzeug ein Gestänge 3 auf, an welchem zumindest ein Antriebsrad, welches von einem elektromotorischen Antrieb antreibbar ist, vorgesehen ist. Das Antriebsrad rollt auf dem Schienenteil 2 der Anlage ab und treibt dabei in Art eines Reibradantriebs das Schienenfahrzeug an. Ab einem kritischen Wert an Antriebsdrehmoment des elektromotorischen Antriebs dreht das Antriebsrad durch, weil es die Haftung verliert und somit statt Haftreibung Gleitreibung bewirkt ist zwischen Antriebsrad und Schienenteil.In this case, the rail vehicle on a linkage 3, on which at least one drive wheel, which is driven by an electric motor drive, is provided. The drive wheel rolls off on the rail part 2 of the system and thereby drives the rail vehicle in the manner of a friction wheel drive. From a critical value of drive torque of the electromotive drive, the drive wheel rotates because it loses adhesion and thus instead of static friction sliding friction is effected between the drive wheel and rail part.

Die Schienenstrecke ist aus in Schienenrichtung hintereinander angeordneten Schienenteilen 2 zusammengesetzt. Dabei sind ebene, also nicht ansteigende, Schienenstreckenabschnitte, insbesondere in denen also keine Hangabtriebskraft wirksam ist, vorgesehen und auch Steigungsstreckenabschnitt, also Streckenabschnitte mit Steigung, in denen eine Hangabtriebskraft wirkt.The rail track is composed of rail parts 2 arranged one behind the other in the rail direction. In this case, even, ie not rising, rail sections, in particular in which no downgrade force is thus effective, provided and also slope section, ie sections with slope, in which a downgrade force acts.

Das Antriebsdrehmoment des elektromotorischen Antriebs ist derart dimensioniert, dass die durch das maximal erzeugbare Drehmoment maximal erzeugbare Antriebskraft kleiner ist als die Hangabtriebskraft im Steigungsstreckenabschnitt.The drive torque of the electromotive drive is dimensioned such that the maximum producible by the maximum torque torque can be smaller than the downhill force in the slope section section.

Daher sind in einem solchen Steigungsstreckenabschnitt Zusatzantriebe vorgesehen. Hierzu sind in dem jeweiligen Steigungsstreckenabschnitt Polradantriebe vorgesehen.Therefore, additional drives are provided in such a pitch section. For this purpose, pole wheel drives are provided in the respective pitch section.

Diese stationär angeordneten Polradantriebe umfassen jeweils eine Polradscheibenanordnung, deren Polradscheiben 1 mit einem am Schienenfahrzeug angeordneten Reaktionsteil 20 zusammenwirkt.These stationary arranged Polradantriebe each comprise a Polradscheibenanordnung, the Polradscheiben 1 cooperates with a arranged on the rail vehicle reaction member 20.

Der Abstand zwischen entlang der Schienenrichtung im Steigungsstreckenabschnitt angeordneten Polradscheibenanordnungen ist kleiner als die Länge des Reaktionsteils 20 in Schienenrichtung. Somit wird das Schienenfahrzeug stets durch mindestens zwei in Schienenrichtung voneinander beabstandete Polradscheibenanordnung angetrieben, wenn die Hangabtriebskraft auf das Schienenfahrzeug wirkt.The distance between arranged along the rail direction in the pitch section section Polradscheibenanordnungen is smaller than the length of the reaction part 20 in the rail direction. Thus, the rail vehicle is always driven by at least two spaced in the rail direction Polradscheibenanordnung when the downgrade force acts on the rail vehicle.

Die Polradscheiben 1 der jeweiligen Polradscheibenanordnung werden von einem jeweiligen Motor in Drehbewegung versetzt, vorzugsweise sobald das Schienenfahrzeug des Steigungsstreckenabschnitt erreicht. Hierzu sind Sensoren an der Strecke vorgesehen, die das Eintreffen des Schienenfahrzeugs detektieren.The Polradscheiben 1 of the respective Polradscheibenanordnung be offset by a respective motor in rotational movement, preferably as soon as the rail vehicle reaches the slope stretch section. For this purpose, sensors are provided on the track, which detect the arrival of the rail vehicle.

Der Reibradantrieb des Schienenfahrzeugs wird angetrieben von einem am Gestänge 3 befestigten Elektromotor 5, welcher ein Getriebe antreibt, mit dessen Abtriebswelle 4 das Reibrad drehfest verbunden ist. Das Reibrad ist in Reibkontakt mit dem Schienenteil 2, entlang dessen das Schienenfahrzeug geführt ist.The friction wheel drive of the rail vehicle is driven by a fixed to the linkage 3 electric motor 5, which drives a transmission with the output shaft 4, the friction wheel is rotatably connected. The friction wheel is in frictional contact with the rail part 2, along which the rail vehicle is guided.

Die Polradscheiben 1 einer jeweiligen Polradscheibenanordnung weisen an ihrer dem Reaktionsteil zugewandten Seite Dauermagnete auf, die in Umfangsrichtung der jeweiligen Polradscheibe gleichmäßig voneinander beabstandet sind. Vorzugsweise sind diese Dauermagnete auf demselben Radialabstand zur Achse der die Polradscheibe 1 antreibenden Welle angeordnet, wobei die Welle mit der Rotorwelle des Motors verbunden ist. Der Motor ist in den Figuren nicht dargestellt und vorzugsweise als Elektromotor ausgeführt.The Polradscheiben 1 a respective Polradscheibenanordnung have on their side facing the reaction part permanent magnets, which are equally spaced in the circumferential direction of the respective Polradscheibe from each other. Preferably, these permanent magnets are arranged at the same radial distance from the axis of the pole wheel disk 1 driving shaft, wherein the shaft is connected to the rotor shaft of the motor. The engine is not shown in the figures and preferably designed as an electric motor.

Wie in Figur 2 und 3 gezeigt, sind bei einer jeweiligen Polradscheibenanordnung auf der Welle mehrere Polradscheiben 1 angeordnet. Dabei sind die dem Reaktionsteil 20 zugewandten, jeweils mit Dauermagneten bestückten Seitenflächen der Polradscheiben 1 voneinander beabstandet, so dass das Reaktionsteil zwischen die Polradscheiben 1 hineinragt.As in FIG. 2 and 3 Shown in a respective Polradscheibenanordnung on the shaft a plurality of Polradscheiben 1 are arranged. Here are the reaction part 20 facing, each equipped with permanent magnets side surfaces of the Polradscheiben first spaced apart, so that the reaction part protrudes between the Polradscheiben 1.

Das Reaktionsteil 20 weist einen E-förmigen Querschnitt auf und ist in Schienenrichtung langgestreckt ausgeführt. Somit weist also das Reaktionsteil 20 zwei Außenschenkelbereiche und einen Mittelschenkelbereiche, die über einen Jochabschnitt verbunden sind, der als Halteabschnitt fungiert.The reaction part 20 has an E-shaped cross section and is elongated in the rail direction. Thus, therefore, the reaction part 20 has two outer leg portions and a middle leg portions which are connected via a yoke portion, which functions as a holding portion.

Die von den Polradscheiben 1 relativ am Reaktionsteil 20 vorbeibewegten Dauermagnete erzeugen in dem metallisch ausgeführten Reaktionsteil 20 Wirbelströme und somit als Reaktionskraft eine Vorschubskraft für das Schienenfahrzeug.The moving from the Polradscheiben 1 relative to the reaction member 20 permanent magnets generate 20 in the metallic reaction part carried eddy currents and thus as a reaction force a feed force for the rail vehicle.

Die beiden axial äußeren Polradscheiben 1 müssen nur auf ihrer dem jeweiligen Außenschenkel des Reaktionsteils 20 zugeordneten Stirnseitenfläche Dauermagnete aufweisen. Auf der vom Reaktionsteil 20 abgewandten Seite sind also keine Dauermagnete vorzusehen.The two axially outer Polradscheiben 1 must have only on their respective outer leg of the reaction part 20 associated end face permanent magnets. On the side remote from the reaction part 20 side so no permanent magnets are provided.

Jeder der Schenkelbereiche des Reaktionsteil 20 ist als dünnes Blechteil ausführbar und/oder das Reaktionsteil 20 ist als Stranggussteil ausführbar. Vorzugsweise ist Aluminium als Material für das Reaktionsteil 20 verwendet.Each of the leg portions of the reaction part 20 can be executed as a thin sheet metal part and / or the reaction part 20 can be executed as a continuous casting. Preferably, aluminum is used as the material for the reaction part 20.

Vom Motor aus ist also eine erste, einseitig mit Dauermagneten bestückte Polradscheibe 1 auf der vom Motor in Drehbewegung versetzbaren Welle angeordnet und mit dieser drehfest verbunden.From the motor so a first, one-sided equipped with permanent magnets Polradscheibe 1 is arranged on the displaceable by the motor in rotary shaft and rotatably connected thereto.

Auf der Welle ist auf der vom Motor abgewandten Seite der ersten Polradscheibe 1 eine zweite Polradscheibe 1 angeordnet, die beidseitig, also axial beidseitig, bestückt ist mit Dauermagneten. Zwischen die erste und zweite Polradscheibe ragt einer der Außenschenkel des Reaktionsteils 20 hinein, insbesondere möglichst nahe an die Dauermagnete der ersten und zweiten Polradscheibe 1 heran. Somit überdeckt der Außenschenkel des Reaktionsteils 20 zumindest teilweise denselben Radialabstandsbereich wie der mit Dauermagneten bestückte Bereich der ersten und zweiten Polradscheibe 1.On the shaft, a second Polradscheibe 1 is arranged on the side facing away from the motor side of the first Polradscheibe 1, which is on both sides, ie axially on both sides, equipped with permanent magnets. Between the first and second Polradscheibe protrudes one of the outer leg of the reaction part 20, in particular as close as possible to the permanent magnets of the first and second Polradscheibe 1 zoom. Thus, the outer leg of the reaction part 20 at least partially covers the same radial distance range as the area of the first and second rotor disk 1 equipped with permanent magnets.

Auf der Welle ist weiterhin auf der vom Motor abgewandten Seite der zweiten Polradscheibe 1 eine dritte Polradscheibe 1 angeordnet, die beidseitig, also axial beidseitig, bestückt ist mit Dauermagneten. Zwischen die dritte und zweite Polradscheibe ragt der Mittelschenkel des Reaktionsteils 20 hinein, insbesondere möglichst nahe an die Dauermagnete der dritten und zweiten Polradscheibe 1 heran. Somit überdeckt der Mittelschenkel des Reaktionsteils 20 zumindest teilweise denselben Radialabstandsbereich wie der mit Dauermagneten bestückte Bereich der dritten und zweiten Polradscheibe 1.On the shaft is further arranged on the side facing away from the motor side of the second Polradscheibe 1, a third Polradscheibe 1, which is on both sides, ie axially on both sides, equipped with permanent magnets. Between the third and second Polradscheibe the center leg of the reaction part 20 protrudes, in particular as close as possible to the permanent magnets of the third and second Polradscheibe 1 zoom. Thus, the center leg of the reaction part 20 at least partially covers the same radial distance range as the area of the third and second rotor disk 1 equipped with permanent magnets.

Auf der Welle ist außerdem noch auf der vom Motor abgewandten Seite der dritten Polradscheibe 1 eine vierte Polradscheibe 1 angeordnet, die einseitig, also axial einseitig, bestückt ist mit Dauermagneten auf der der dritten Polradscheibe 1 zugewandten Seite. Zwischen die dritte und vierte Polradscheibe ragt der andere Außenschenkel des Reaktionsteils 20 hinein, insbesondere möglichst nahe an die Dauermagnete der dritten und vierten Polradscheibe 1 heran. Somit überdeckt der Außenschenkel des Reaktionsteils 20 zumindest teilweise denselben Radialabstandsbereich wie der mit Dauermagneten bestückte Bereich der dritten und vierten Polradscheibe 1.On the shaft is also still on the side facing away from the motor side of the third Polradscheibe 1 a fourth Polradscheibe 1 arranged on one side, ie axially on one side, equipped with permanent magnets on the third Polradscheibe 1 side facing. Between the third and fourth Polradscheibe the other outer leg of the reaction part 20 protrudes, in particular as close as possible to the permanent magnets of the third and fourth Polradscheibe 1 zoom. Thus, the outer leg of the reaction part 20 at least partially covers the same radial distance range as the area of the third and fourth rotor disk 1 equipped with permanent magnets.

Das Reaktionsteil ist mit dem Gestänge 3 des Schienenfahrzeugs verbunden und überträgt somit die mittels der mit dem Reaktionsteil 20 zusammenwirkenden Polradscheiben 1 zusätzlich eingebrachte Antriebskraft auf das Schienenfahrzeug.The reaction part is connected to the linkage 3 of the rail vehicle and thus transmits the additionally applied by means of the cooperating with the reaction member 20 Polradscheiben 1 driving force to the rail vehicle.

Die maximal realisierbare Eintauchtiefe des Reaktionsteils 20 ist begrenzt durch den Außendurchmesser der vom nicht dargestellten Motor angetriebenen Welle.The maximum feasible immersion depth of the reaction part 20 is limited by the outer diameter of the shaft driven by the motor, not shown.
