Passagierschienenfahrzeuge für den Nahverkehr wie U-Bahnen sind fast ausschließlich mit Mittelpufferkupplungen  Passenger rail vehicles for public transport such as subways are almost exclusively with central buffer couplings
ausgestattet. Diese Mittelpufferkupplungen können so fitted. These central buffer couplings can do so

fahrzeugführerlose Schienenfahrzeuge erforderlich, welche alle betrieblichen Rangier- und Kuppelvorgänge Vehicle-guided rail vehicles required, which all operational shunting and dome operations

Die nichtgekoppelten  Central buffer couplings to each other, which must not exceed a certain level, otherwise the dome operation is not automatically executable. The uncoupled
Kupplungen am Zugbeginn und am Zugende sind mit einer geeigneten Vorrichtung federnd in Mittelstellung gehalten um eine Schwingbewegung der Kupplung während der Fahrt zu verhindern. Dadurch kann ein Kuppelvorgang in einem Clutches at the beginning of the train and at the end of the train are resiliently held in the middle position with a suitable device in order to prevent a swinging movement of the clutch while driving. This can be a coupling process in one

In engeren Gleisradien ist somit nur mit manueller Hilfe ein Track curves are only executed if the curve radius is one certain value is not exceeded and the so-called gripping range of the clutch is not left. In narrower track radii is thus only with manual help
Kuppelvorgang möglich. Gemäß dem Stand der Technik kann dieses Problem teilweise mittels eines Gestänges zwischen der Mittelpufferkupplung und dem ersten folgenden Drehgestell reduziert werden, welches die Mittelpufferkupplung Dome operation possible. According to the prior art, this problem can be partially reduced by means of a linkage between the central buffer coupling and the first following bogie, which forms the central buffer coupling
entsprechend dem Drehwinkel des Drehgestells nachführt. according to the angle of rotation of the bogie tracks.
Dieses Verfahren weist beträchtliche Nachteile auf, da das Gestänge Bauraum an der Unterseite des Fahrzeugs benötigt und regelmäßiger Wartung bedarf. Weiters ist es an Übergängen von einem geraden Gleisabschnitt in eine Kurve (Kurveneinfahrt) wirkungslos, da an dieser Stelle das betreffende Drehgestell noch nicht gegenüber dem Wagenkasten verdreht ist. This method has considerable disadvantages, as the linkage requires space at the bottom of the vehicle and requires regular maintenance. Furthermore, it is at transitions from a straight track section in a curve (corner entry) ineffective, since at this point the bogie in question is not yet rotated relative to the car body.
Darstellung der Erfindung Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren und eine Einrichtung zur Zentrierung einer ungekuppelten Mittelpufferkupplung anzugeben, womit bei jedem von dem Fahrzeug befahrbaren Gleisradius die nichtgekoppelten The invention is therefore based on the object of specifying a method and a device for centering an uncoupled central buffer coupling, with which the uncoupled at each of the vehicle traversable track radius
Mittelpufferkupplungen zentriert werden können. Central buffer couplings can be centered.
Die Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 und ein Schienenfahrzeug nach Anspruch 6 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand untergeordneter Ansprüche . The object is achieved by a method having the features of claim 1 and a rail vehicle according to claim 6. Advantageous embodiments are the subject of the subordinate claims.
Dem Grundgedanken der Erfindung nach wird ein Verfahren zur Zentrierung einer ungekuppelten Mittelpufferkupplung eines Schienenfahrzeugs beschrieben, wobei die Mittelpufferkupplung mittels eines kraftbetriebenen Antriebs horizontal schwenkbar angeordnet ist und folgende Verfahrensschritte abgearbeitet werden : According to the basic idea of the invention, a method for centering an uncoupled central buffer coupling of a rail vehicle is described, wherein the central buffer coupling is arranged horizontally pivotable by means of a power-driven drive and the following process steps are performed:
- erfassen mindestens eines bestimmten Kriteriums durch eine Steuereinrichtung,  capture at least one particular criterion by a control device,
- bestimmen einer Sollstellung der Mittelpufferkupplung mittels des Kriteriums,  determine a desired position of the central buffer coupling by means of the criterion,
- ansteuern des Antriebs durch die Steuereinrichtung bis die Mittelpufferkupplung die Sollstellung eingenommen hat.  - Actuate the drive by the controller until the central buffer clutch has assumed the desired position.
Dadurch ist der Vorteil erzielbar, die Mittelpufferkupplung jederzeit in eine solche Position (Winkellage zur As a result, the advantage can be achieved, the central buffer coupling at any time in such a position (angular position for
Fahrzeuglängsache) stellen zu können, dass ein Kuppelvorgang ausführbar ist. Dabei wird die Kupplung kraftunterstützt in eine Lage (Sollstellung) gebracht, in welcher sie sich in ihrem jeweiligen Greifbereich befindet, sodass ohne manuelle Einwirkung ein automatischer Kuppelvorgang ausführbar ist. Fahrzeuglängsache) to make that a dome operation is executable. The clutch is power assisted brought into a position (debit position) in which it is in their respective gripping area, so that an automatic dome operation can be performed without manual intervention.
Dazu ist ein Kraftantrieb vorzusehen, mittels welchem die Mittelpufferkupplung in einem bestimmten Winkelbereich horizontal verschwenkbar ist. Typischerweise ist dabei ein Winkelbereich von H— 30 Grad zur Fahrzeuglängsachse For this purpose, a power drive is provided, by means of which the central buffer coupling can be pivoted horizontally in a certain angular range. Typically, this is an angle range of H-30 degrees to the vehicle longitudinal axis

Weiters ist eine Steuereinrichtung vorzusehen, welche Mittel zur Ansteuerung des Antriebs umfasst, beispielsweise die dazu erforderliche Leistungselektronik. Diese Steuereinrichtung ist zur Zuführung von Sensorsignalen auszustatten, mittels welchen der Steuereinrichtung bestimmte Kriterien zuführbar sind. Aus diesen, das Kriterium beschreibenden Signalen ermittelt die Steuereinrichtung eine jeweils optimale  Furthermore, a control device is to be provided which comprises means for controlling the drive, for example the power electronics required for this purpose. This control device is to be equipped to supply sensor signals by means of which specific criteria can be supplied to the control device. From these signals describing the criterion, the control device determines a respective optimum one
Winkellage der Mittelpufferkupplung zur Fahrzeuglängsachse (Sollstellung) , bei welcher die Mittelpufferkupplung mittig in ihrem Greifbereich liegt. In weiterer Folge steuert die Steuereinrichtung den Antrieb so an, dass die Angular position of the central buffer coupling to the vehicle longitudinal axis (nominal position), in which the central buffer coupling is located centrally in its gripping area. Subsequently, the controls Control device to the drive so that the
Mittelpufferkupplung diese Sollstellung einnimmt. Central buffer coupling assumes this nominal position.
Er ist besonders vorteilhaft, das erfindungsgemäße Verfahren ausschließlich vor einem geplanten Kuppelvorgang auszuführen. Die Winkellage einer ungekuppelten Mittelpufferkupplung (jeweils an den Zugenden) ist während des Betriebs He is particularly advantageous to perform the inventive method exclusively before a planned coupling process. The angular position of an uncoupled central buffer coupling (in each case at the Zugenden) is during operation
unerheblich und nur bei einem Kuppelvorgang relevant. Durch den Verzicht auf kontinuierliches Ansteuern des Antriebs kann der Energieverbrauch reduziert und der Verschleiß des irrelevant and relevant only in a coupling process. By dispensing with continuous driving of the drive, the energy consumption can be reduced and the wear of the
Antriebs minimiert werden. Drive can be minimized.
Als Kriterium zur Bestimmung der Sollstellung der As a criterion for determining the nominal position of
ungekuppelten Mittelpufferkupplung kann dabei, ähnlich wie bei bekannten mechanischen Lösungen der Drehwinkel des der Kupplung nächsten Drehgestells gegenüber der ungekuppelten central buffer coupling can, similar to known mechanical solutions, the angle of rotation of the next coupling bogie over the
Fahrzeuglängsachse genutzt werden. Dieser Drehwinkel kann mit gebräuchlicher Sensorik einfach erfasst werden und ergibt eine genaue Möglichkeit der Ermittlung des aktuellen  Vehicle longitudinal axis can be used. This angle of rotation can be easily detected with conventional sensors and provides an accurate way of determining the current
Kurvenradius. Aus diesem Radius kann die erforderliche horizontale Verschwenkung, d.h. die Sollstellung der Turning radius. From this radius, the required horizontal pivoting, i. the debit position of
Mittelpufferkupplung ermittelt werden. In diese Berechnung fließt die Geometrie des konkreten Schienenfahrzeugs (z.B. die Länge der Mittelpufferkupplung, der Ort des Drehpunkts, der Greifbereich) ein. Nachteilig ist dabei jedoch, dass bei einem Übergang von geraden in gebogene Gleisabschnitte keine Mittenzentrierung erfolgt. Central buffer coupling can be determined. In this calculation, the geometry of the concrete rail vehicle (e.g., the length of the center buffer coupling, the location of the fulcrum, the gripping area) flows into it. A disadvantage, however, is that in a transition from straight to curved track sections no centering is done.
Ein weiteres Kriterium zur Bestimmung der Sollstellung der ungekuppelten Mittelpufferkupplung ist die Position des Schienenfahrzeugs auf der Strecke. Auf Strecken, welche hinreichend exakt vermessen sind, kann aus der Ermittlung der aktuellen Position auf der Strecke eine für diese Position optimale Verschwenkung der Mittelpufferkupplung bestimmt werden. Dazu ist eine hinreichend genaue Positionsbestimmung erforderlich. Dadurch kann jedoch auch an einem Übergang von geraden in gebogene Gleisabschnitte eine exakte Another criterion for determining the nominal position of the uncoupled central buffer coupling is the position of the rail vehicle on the track. On routes that are measured with sufficient accuracy, the determination of the current position on the track can be done for this position optimal pivoting of the central buffer coupling are determined. For this purpose, a sufficiently accurate position determination is required. As a result, however, can also at a transition from straight to curved track sections an exact
Mittenzentrierung erfolgen. Centering done.
Ein weiteres, vorteilhaftes Kriterium kann mittels Another, advantageous criterion can by means of
Bilderkennung der Gleislage gewonnen werden. Mittels Image recognition of the track position can be obtained. through
geeigneter Bilderkennungsverfahren kann kontinuierlich die Lage der Mittelpufferkupplung bezogen auf die Geleise ermittelt werden. Aus dieser Ermittlung kann ein suitable image recognition method can be continuously determined the position of the central buffer coupling with respect to the tracks. From this determination can a
Korrekturwert bestimmt werden und die Mittelpufferkupplung in ihre Sollstellung bewegt werden. Zur optischen Erfassung der Position können Methoden der klassischen Bilderkennung oder auch Stereokameras und auf Stereokameras adaptierte Correction value can be determined and the central buffer coupling are moved to their desired position. For optical detection of the position methods of classical image recognition or even stereo cameras and adapted to stereo cameras
Bilderkennungsverfahren eingesetzt werden. Für eine besonders exakte Erfassung ist es empfehlenswert eine aktive Abtastung des Bereichs vor dem Fahrzeug mittels Lichtmustern oder Laserabtastung vorzusehen.  Image recognition method can be used. For a particularly accurate detection, it is advisable to provide active scanning of the area in front of the vehicle by means of light patterns or laser scanning.
Es ist empfehlenswert, alle zur automatischen Kupplung einsetzbaren Mittelpufferkupplungen eines Fahrzeugs, bzw. eines Zugverbands mit einer erfindungsgemäßen Einrichtung auszustatten. Dadurch kann ein vollautomatischer Fahrbetrieb auf der gesamten Strecke sichergestellt werden. Dies ist insbesondere vorteilhaft, da solcherart sowohl ein It is recommended to equip all for automatic coupling usable central buffer couplings of a vehicle, or a train with a device according to the invention. This ensures fully automatic driving on the entire route. This is particularly advantageous, since both such
vollautomatischer Rangierbetrieb zur vollautomatischen fully automatic shunting operation for fully automatic
Zusammenstellung der erforderlichen Zugkombinationen als auch ein Bergebetrieb möglich ist, bei welchem ein defekter Zug durch einen weiteren Zug auf jeder Position der Strecke geborgen werden kann. Der Antrieb der Zentrierung einer ungekuppelten Mittelpufferkupplung kann mit allen in Schienenfahrzeugen gebräuchlichen Mitteln erfolgen, beispielsweise mittels Druckluft oder elektrischem Antrieb. Mittelpufferkupplungen sind gemäß dem Stand der Technik mit einer federnden Compilation of the required train combinations as well as a mining operation is possible in which a defective train can be recovered by another train at each position of the route. The drive of centering an uncoupled central buffer coupling can be done with all commonly used in rail vehicles means, for example by means of compressed air or electric drive. Central buffer couplings are according to the prior art with a resilient
Rückführung in ihre geometrische Mittellage ausgestattet. Dadurch wird ein willkürliches Bewegen der Kupplung während des Fahrbetriebs verhindert, welches das Kupplungslager und die Endanschläge belastet und zu Geräuschentwicklung führt. Dabei ist eine fest angeordnete Mittenzentrierung mit dem Fahrzeugrahmen verbunden, um welche die Kupplungsstange drehbar ist und sich mittels Federkraft in die Mittelstellung selbsttätig rückführt. Es ist besonders vorteilhaft, solche Mittelpufferkupplungen mit einer erfindungsgemäßen  Equipped return to its geometric center position. This prevents an arbitrary movement of the clutch during driving, which loads the clutch bearing and the end stops and leads to noise. In this case, a fixed centering is connected to the vehicle frame, about which the coupling rod is rotatable and automatically returns by means of spring force in the middle position. It is particularly advantageous to use such central buffer couplings with an inventive

Mittelstellung in welche die Kupplungsstange sich automatisch rückführt, in einem bestimmten Winkelbereich einstellbar ist. Dazu ist die Mittenzentrierung mit einem vorzugsweise elektrischen Drehantrieb auszustatten. Besonders vorteilhaft dabei ist, dass der sogenannte Überlastschutz unverändert wirkungsvoll bleibt und die Kupplungsstange gegen die Middle position in which the coupling rod automatically returns, is adjustable in a certain angle range. For this purpose, the centering center is to be equipped with a preferably electric rotary drive. It is particularly advantageous that the so-called overload protection remains effective and the coupling rod against the
Federkraft weiterhin auslenkbar bleibt. Ein weiterer Vorteil liegt darin, dass in gekuppeltem Betrieb der auf die Spring force remains deflectable. Another advantage is that in coupled operation of the on the

In dieser Vehicles with central buffer couplings without spring-assisted centering with centering of an uncoupled one Equip central buffer coupling, wherein preferably a linear drive can be used. In this
Ausführungsform muß der Linearantrieb mit geeigneten Mittel eines Überlastungsschutzes (Federn, Rutschkupplung) ausgestattet werden und für den gekuppelten Betrieb des Fahrzeugs auskoppelbar sein. Bei Druckluftlinearantrieben kann dies durch Entlüften des Pneumatischen Antriebs erfolgen . Embodiment, the linear drive must be equipped with suitable means of overload protection (springs, slip clutch) and be decoupled for the coupled operation of the vehicle. For pneumatic linear actuators, this can be done by venting the pneumatic actuator.
Eine weitere Ausführungsform der Erfindung sieht vor, die Steuereinrichtung zusammen mit einer Kupplungssteuerung aufzubauen, welche den eigentlichen Kuppelvorgang steuert. Dadurch kann ein integriertes, kompaktes Zentrier- und Steuergerät geschaffen werden.

As a result, an integrated, compact centering and control device can be created.
