Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Überwachung von Koppelelementen eines Fahrzeugs.The invention relates to a method and a device for monitoring coupling elements of a vehicle.

Stand der TechnikState of the art

Koppelelemente eines Fahrzeugs, beispielsweise Federelemente oder Verbindungselemente, unterliegen einer Abnutzung beziehungsweise einer Alterung. Weder die Abnutzung noch die Alterung der Koppelelemente sind beim Betrieb des Fahrzeugs mit dem heutigen Stand der Technik vermeidbar. Daher müssen diese Koppelelemente in regelmäßigen Zeitabständen oder nach einer bestimmen Kilometerleistung des Fahrzeugs im Rahmen einer Revision ausgetauscht werden. Die Abnutzung beziehungsweise Alterung solcher Koppelelemente hat Einfluss auf deren Materialeigenschaften. Drei Hauptursachen für die Änderung dieser Materialeigenschaften sind die fortschreitende Zeit, die einwirkenden Umwelteinflüsse und die mechanische Belastung. Diese drei Hauptursachen führen zu einer Gesamtschädigung der Koppelelemente, welche für jedes Koppelelement unterschiedlich ist.Coupling elements of a vehicle, for example spring elements or connecting elements, are subject to wear or aging. Neither the wear nor the aging of the coupling elements can be avoided during operation of the vehicle with the current state of the art. Therefore, these coupling elements must be replaced at regular intervals or after a certain mileage of the vehicle as part of a revision. The wear or aging of such coupling elements has an influence on their material properties. Three main causes of the change in these material properties are the progressive time, the environmental influences and the mechanical stress. These three main causes lead to a total damage of the coupling elements, which is different for each coupling element.

Koppelelemente eines Fahrzeuges unterliegen einem großen Spektrum an mechanischen Belastungen. Diese mechanischen Belastungen sind von der jeweiligen Betriebsart sowie vom Zustand der mit dem Fahrzeug befahrenen Strecken abhängig. Zusätzlich weisen die drei Hauptursachen für die Änderung der Materialeigenschaften ein nichtlineares Schädigungsverhalten auf, so dass eine Prognose der zu erwartenden Gesamtschädigung nicht möglich ist.Coupling elements of a vehicle are subject to a large spectrum of mechanical loads. These mechanical loads depend on the respective operating mode and on the condition of the routes traveled by the vehicle. In addition, the three main causes for the change in material properties show a non-linear damage behavior, so that it is not possible to forecast the total damage to be expected.

Nach dem Stand der Technik wird daher der Zeitpunkt der Revision nicht auf Grund der tatsächlichen Gesamtschädigung der Koppelelemente festgelegt, sondern auf Grund einer bestimmten Kilometerleistung des Fahrzeugs, nach Ablauf einer bestimmten Zeitspanne seit einer vorangegangenen Revision, oder einer Kombination daraus.According to the prior art, therefore, the date of the revision is not due to the actual total damage of the Set coupling elements, but on the basis of a certain mileage of the vehicle, after a certain period of time since a previous revision, or a combination thereof.

Demzufolge besteht die Möglichkeit, dass im Rahmen einer Revision Koppelelemente des Fahrzeugs getauscht werden, welche noch im Fahrzeug einsetzbar wären.Consequently, there is the possibility that as part of a revision coupling elements of the vehicle are exchanged, which would still be used in the vehicle.

Es besteht auch die Möglichkeit, dass sich Koppelelemente eines Fahrzeugs im Einsatz befinden, welche auf Grund ihrer Gesamtschädigung nicht mehr den Erfordernissen genügen.There is also the possibility that coupling elements of a vehicle are in use, which no longer meet the requirements due to their total damage.

Das Dokument JP 2008 254578 A beschreibt ein Verfahren zur Bestimmung abnormale Betriebszustände in Koppelelementen.The document JP 2008 254578 A describes a method for determining abnormal operating conditions in coupling elements.

Zusammenfassung der ErfindungSummary of the invention Technische AufgabeTechnical task

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Überwachung von Koppelelementen eines Fahrzeugs zur Feststellung deren Einsatzeignung bereitzustellen.The invention has for its object to provide a method and apparatus for monitoring coupling elements of a vehicle to determine their mission suitability.

Technische LösungTechnical solution

Erfindungsgemäß wird diese Aufgabe gelöst durch ein Verfahren, bei dem für ein zu überwachendes Koppelelement zumindest eine maßgebliche Relativbewegungsrichtung bestimmt wird, Relativbewegungen entlang der maßgeblichen Relativbewegungsrichtung des zu überwachenden Koppelelements gemessen und gespeichert werden, und eine Auswertung der gespeicherten Relativbewegungen erfolgt.According to the invention, this object is achieved by a method in which at least one relevant relative movement direction is determined for a coupling element to be monitored, relative movements are measured and stored along the relevant relative direction of movement of the coupling element to be monitored, and an evaluation of the stored relative movements takes place.

Koppelelemente können in den verschiedensten Bauformen ausgeführt sein. Die maßgeblichen Relativbewegungsrichtungen werden in Abhängigkeit der Bauform der Koppelelemente und der betriebsmäßig auf das Koppelelement einwirkenden Kräfte bestimmt. Für das zu überwachende Koppelelement kann nur eine Relativbewegungsrichtung als maßgeblich bestimmt werden, es können aber auch mehrere maßgebliche Relativbewegungsrichtungen pro Koppelement bestimmt werden.Coupling elements can be designed in a variety of designs. The relevant relative movement directions are determined depending on the design of the coupling elements and the forces acting on the coupling element forces. For the coupling element to be monitored, only one direction of relative movement can be determined to be decisive but also several significant relative directions of movement per Koppelement can be determined.

Die Relativbewegungen entlang der zumindest einen maßgeblichen Relativbewegungsrichtung des zu überwachenden Koppelelements werden gemessen und gespeichert. Die gespeicherten Relativbewegungen werden anschließend ausgewertet.The relative movements along the at least one relevant direction of relative movement of the coupling element to be monitored are measured and stored. The stored relative movements are then evaluated.

Die Koppelelemente führen durch mechanische Belastung Relativbewegungen aus, welche zu einer Schädigung der Koppelelemente führen.The coupling elements perform by mechanical load relative movements, which lead to damage to the coupling elements.

Der Vorteil des erfindungsgemäßen Verfahrens ergibt sich dadurch, dass durch Messung und Auswertung dieser Relativbewegungen festgestellt werden kann, ob die Koppelelemente noch den Erfordernissen genügen, beziehungsweise wie weit die Schädigung der Koppelelemente fortgeschritten ist. Damit kann auch abseits einer Revision jederzeit die Einsatzeignung der Koppelelemente im Fahrzeug bestimmt werden und gegebenenfalls rasch ein Austausch von geschädigten Koppelelementen im Rahmen einer Revision veranlasst werden.The advantage of the method according to the invention results from the fact that it can be determined by measuring and evaluating these relative movements, whether the coupling elements still meet the requirements, or how far the damage of the coupling elements has progressed. This means that the use of the coupling elements in the vehicle can also be determined at any time apart from a revision and, if necessary, an exchange of damaged coupling elements can be promptly initiated as part of a revision.

Ein weiterer Vorteil des erfindungsgemäßen Verfahrens ist, dass im Rahmen einer Revision nur jene Koppelelemente des Fahrzeugs getauscht werden, an welchen auch tatsächlich eine Schädigung durch das erfindungsgemäße Verfahren festgestellt wurde.A further advantage of the method according to the invention is that, in the context of a revision, only those coupling elements of the vehicle are exchanged, on which a damage has actually been determined by the method according to the invention.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens werden die Relativbewegungen des zu überwachenden Koppelelements mittels jeweils eines entlang der maßgeblichen Relativbewegungsrichtung angeordneten Gebers und eines Nehmers gemessen und gespeichert.In a preferred embodiment of the method according to the invention, the relative movements of the coupling element to be monitored are measured and stored by means of a respective sensor arranged along the relevant relative movement direction and a receiver.

Der Abstand des Gebers und des Nehmers entlang der maßgeblichen Relativbewegungsrichtung ist variierbar. Damit können sämtliche Relativbewegungen in der maßgeblichen Relativbewegungsrichtung gemessen und gespeichert werden.The distance between the transmitter and the receiver along the relevant direction of relative movement is variable. Thus, all relative movements in the relevant direction of relative movement can be measured and stored.

In einer weiteren bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens wird die Anzahl jener Relativbewegungen des zu überwachenden Koppelelements gespeichert, die über einen vorher festgelegten Schwellenwert liegen.In a further preferred embodiment of the method according to the invention, the number of those relative movements of the coupling element to be monitored is stored, which are above a predetermined threshold.

Es wird dabei jede Relativbewegung des Koppelelements, welche über dem Schwellenwert liegt, gleichwertig als normierte Einheit gezählt. Relativbewegungen des Koppelelements, welche unter dem Schwellenwert liegen, werden nicht gezählt. Diese Art der Zählung gibt Auskunft über die Anzahl der Relativbewegungen, welche größer als der Schwellenwert sind.In this case, each relative movement of the coupling element, which lies above the threshold value, is counted equally as a normalized unit. Relative movements of the coupling element, which are below the threshold, are not counted. This type of count provides information about the number of relative movements which are greater than the threshold value.

Damit kann die Empfindlichkeit des erfindungsgemäßen Verfahrens eingestellt werden, und Relativbewegungen des Koppelelements, welche nicht maßgeblich zu einer Schädigung des Koppelelements beitragen, können herausgefiltert werden.Thus, the sensitivity of the method according to the invention can be adjusted, and relative movements of the coupling element, which do not contribute significantly to a damage of the coupling element, can be filtered out.

Eine bevorzugte Ausführungsform des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, dass die Auswertung der gespeicherten Relativbewegungen des zu überwachenden Koppelelements durch Vergleichen der Anzahl mit zumindest einem vorher festgelegten Grenzwert erfolgt.A preferred embodiment of the method according to the invention is characterized in that the evaluation of the stored relative movements of the coupling element to be monitored takes place by comparing the number with at least one predetermined limit value.

Übersteigt die Anzahl der gespeicherten Relativbewegungen zumindest einen der vorher festgelegten Grenzwerte, so deutet dies darauf hin, dass das Koppelelement auf Grund seiner Schädigung nicht mehr den Erfordernissen entspricht.If the number of stored relative movements exceeds at least one of the previously defined limit values, this indicates that the coupling element no longer meets the requirements due to its damage.

Die gespeicherten Relativbewegungen werden berührungslos zu einer Empfangseinheit übertragen.The stored relative movements are transmitted without contact to a receiving unit.

Damit können die gespeicherten Relativbewegungen auch während des Betriebs des Fahrzeugs beziehungsweise während der Fahrt zur Empfangseinheit übertragen werden.Thus, the stored relative movements can also be transmitted during operation of the vehicle or while driving to the receiving unit.

Die Auswertung der gespeicherten Relativbewegungen des zu überwachenden Koppelelements erfolgt vorzugsweise nach jeweils im Wesentlichen gleichlangen Zeitintervallen oder nach jeweils im Wesentlichen gleicher Kilometerleistung des Fahrzeugs.The evaluation of the stored relative movements of the coupling element to be monitored is preferably carried out after respectively substantially equal time intervals or after each substantially the same mileage of the vehicle.

Es gilt die Annahme, dass innerhalb dieser gleichlangen Zeitintervalle beziehungsweise nach jeweils gleichen Kilometerleistungen des Fahrzeugs die auf das Koppelelement einwirkenden Kräfte im Mittel gleich groß sind.The assumption is that within these equal time intervals or after each same mileage of the vehicle, the forces acting on the coupling element forces are equal in average.

Durch Vergleich der zu den jeweiligen Zeitpunkten beziehungsweise der nach der jeweiligen Kilometerleistung gespeicherten Relativbewegungen mit vor diesen jeweiligen Zeitpunkten beziehungsweise vor dieser jeweiligen Kilometerleistung gespeicherten Relativbewegungen kann die Schädigung des Koppelelement bestimmt werden.By comparing the relative movements stored at the respective time points or the respective mileage with relative movements stored before these respective times or before the respective mileage, the damage to the coupling element can be determined.

Vorzugsweise wird der Schwellenwert und/oder der Grenzwert auf Basis von Messfahrtdaten, oder aufgrund von Simulationen des Fahrzeuges festgelegt.The threshold value and / or the limit value are preferably determined on the basis of test drive data or on the basis of simulations of the vehicle.

Der Schwellenwert und/oder der Grenzwert, beziehungsweise die Grenzwerte, welche unterschiedlichen Schädigungsstufen des zu untersuchenden Koppelelements entsprechen, können auf Basis der Analyse von Messfahrtdaten in Kombination von Schädigungsmodellen erstellt werden.The threshold value and / or the limit value or the limit values which correspond to different damage levels of the coupling element to be examined can be created on the basis of the analysis of measurement travel data in combination of damage models.

Es ist auch möglich, Messfahrten des Fahrzeugs virtuell nach zu simulieren, um so die Grenzwerte rein virtuell zu generieren.It is also possible to virtually simulate test drives of the vehicle in order to generate the limit values in a purely virtual manner.

Bei der Messfahrt des Fahrzeugs werden die Relativbewegungen des zu überwachenden Koppelelements ausgewertet und der Schwellenwert wird derart festgelegt, dass nur diejenigen Relativbewegungen des Koppelelements gespeichert werden, die maßgeblich zu einer Schädigung desselben beitragen. Die Grenzwerte, welche den unterschiedlichen Schädigungsstufen entsprechen, werden derart festgelegt, dass, wenn die Anzahl der Relativbewegungen des Koppelelements diese Grenzwerte übersteigt, der Status des Bauteiles bezüglich dessen Einsatzeignung herabgestuft wird. So besitzt jedes Koppelement einen Lebensdauer- beziehungsweise Einsatzeignungsstatus, wodurch eine genaue Planung der Revisionsintervalle und somit eine optimale Bauteilausnützung erfolgen kann.During the test drive of the vehicle, the relative movements of the coupling element to be monitored are evaluated and the threshold value is set in such a way that only those relative movements of the coupling element are stored which significantly contribute to the damage thereof. The limit values which correspond to the different damage levels are determined such that, if the number of relative movements of the coupling element exceeds these limits, the status of the component with respect to it Mission suitability is downgraded. Thus, each coupling element has a service life or insertion suitability status, as a result of which precise planning of the inspection intervals and thus optimum utilization of the components can take place.

Ein letzter Grenzwert wird derart festgelegt, dass, wenn die Anzahl der Relativbewegungen des Koppelelements diesen Grenzwert übersteigt, das Koppelelement auf Grund einer Schädigung nicht mehr den Erfordernissen beim Einsatz in Fahrzeugen genügt.A last limit value is set such that when the number of relative movements of the coupling element exceeds this limit, the coupling element due to damage no longer meets the requirements for use in vehicles.

Die zu überwachenden Koppelelemente sind vorzugsweise als Federelemente, Verbindungselemente oder Kombinationen daraus ausgeführt. Beispielsweise sind unter dem Begriff Koppelelement Kombinationen aus zwei Federelementen, aus zwei Verbindungselementen, aus einem Federelement und einem Verbindungselement oder auch beliebige Kombinationen aus mehreren Federelementen, Verbindungselementen oder beiden zu verstehen.The coupling elements to be monitored are preferably designed as spring elements, connecting elements or combinations thereof. For example, the term coupling element is to be understood as meaning combinations of two spring elements, two connecting elements, one spring element and one connecting element, or also any desired combinations of a plurality of spring elements, connecting elements or both.

Das Fahrzeug ist vorzugsweise als Schienenfahrzeug ausgeführt. Mittels des erfindungsgemäßen Verfahrens können unnötige Revisionen der Schienenfahrzeuge verhindert werden. Insbesondere ist dies deshalb von Vorteil, weil Revisionen von Schienenfahrzeugen nur mit einem relativ hohen technischen Aufwand durchgeführt werden können. Außerdem ist das entsprechende Schienenfahrzeug während der Zeitdauer der Revision nicht für den normalen Betrieb verfügbar.The vehicle is preferably designed as a rail vehicle. By means of the method according to the invention, unnecessary revisions of the rail vehicles can be prevented. In particular, this is advantageous because revisions of rail vehicles can only be performed with a relatively high technical complexity. In addition, the corresponding rail vehicle is not available for normal operation during the period of the revision.

Der Revisionszeitpunkt wird vorzugsweise als Ergebnis der Auswertung der gespeicherten Relativbewegungen der zu überwachenden Koppelelemente festgelegt.The revision time is preferably determined as a result of the evaluation of the stored relative movements of the coupling elements to be monitored.

Es kann daher zeitgenau ein Termin für eine Revision festgelegt werden.It is therefore possible to set an appointment for a revision on time.

Mittels der Auswertung der gespeicherten Relativbewegungen der zu überwachenden Koppelelemente erfolgt eine Analyse der Betriebsart, insbesondere hinsichtlich betriebsorientierter Belastungen der Koppelemente.By means of the evaluation of the stored relative movements of the coupling elements to be monitored, an analysis of the Operating mode, in particular with regard to operational loads of the coupling elements.

Mittels Einbindung der Ergebnisse dieser Analyse bei der Festlegung des Grenzwertes oder des Schwellenwertes kann die Genauigkeit des erfindungsgemäßen Verfahrens laufend verbessert werden. Es kann damit ein lernender Prozess generiert werden. Zusätzlich können die Ergebnisse auch in Neuentwicklungen von Koppelelementen einfließen.By incorporating the results of this analysis in the determination of the limit value or the threshold value, the accuracy of the method according to the invention can be continuously improved. It can thus be used to generate a learning process. In addition, the results can also be incorporated in new developments of coupling elements.

Beschreibung der AusführungsformenDescription of the embodiments

In FIG 1 ist beispielhaft und schematisch ein als Schraubenfeder ausgeführtes Koppelelement 1 dargestellt. Für das zu überwachendes Koppelelement 1 wird eine maßgebliche Relativbewegungsrichtung 2 bestimmt. Am Bauteil 9 sind ein Geber 3 und ein Nehmer 4 fixiert. Der Abstand zwischen Geber 3 und Nehmer 4 ist in der maßgeblichen Relativbewegungsrichtung 2 variierbar. Beispielsweise wird dieser Abstand durch auf die Schraubenfeder in der maßgeblichen Relativbewegungsrichtung 2 ausgeübte Zugkräfte vergrößert oder durch auf die Schraubenfeder in der maßgeblichen Relativbewegungsrichtung 2 ausgeübte Druckkräfte verringert. Führt das Koppelelement 1 Relativbewegungen in Richtung der maßgeblichen Relativbewegungsrichtung 2 aus, so führen auch der Geber 3 und/oder der Nehmer 4 diese Relativbewegungen aus. Zumindest ändert sich ihr Abstand entlang der maßgeblichen Relativbewegungsrichtung 2. Damit können Relativbewegungen des zu überwachenden Koppelelements 1 entlang der maßgeblichen Relativbewegungsrichtung 2 gemessen und gespeichert werden. Es werden nur solche Relativbewegungen als Daten gespeichert, die über einen vorher festgelegten Schwellenwert liegen. Diese Daten werden jeweils gleichwertig als normierte Einheit im Nehmer 4 gespeichert. Im Speicher des Nehmers 4 ist letztendlich die Anzahl jener Relativbewegungen gespeichert, die über dem Schwellenwert liegen. Damit können beispielsweise geringste Relativbewegungen, die keinen oder fast keinen Beitrag zu einer Schädigung des Koppelelements 1 leisten, ausgenommen werden.In FIG. 1 is exemplary and schematically illustrated as a helical spring coupling element 1 is shown. For the coupling element 1 to be monitored, a significant direction of relative movement 2 is determined. On the component 9, an encoder 3 and a slave 4 are fixed. The distance between encoder 3 and slave 4 can be varied in the relevant direction of relative movement 2. For example, this distance is increased by tensile forces exerted on the helical spring in the relevant direction of relative movement 2 or by the force exerted on the helical spring in the relevant direction of relative movement 2 Reduced compressive forces. If the coupling element 1 executes relative movements in the direction of the relevant relative movement direction 2, then the encoder 3 and / or the slave 4 also execute these relative movements. At least their distance changes along the relevant relative movement direction 2. Thus, relative movements of the coupling element 1 to be monitored along the relevant relative movement direction 2 can be measured and stored. Only those relative movements are stored as data that are above a predetermined threshold. These data are stored equally as a normalized unit in the receiver 4. The memory of the receiver 4 ultimately stores the number of relative movements which are above the threshold value. Thus, for example, the slightest relative movements, which make no or almost no contribution to a damage of the coupling element 1, are excluded.

Die im Nehmer 4 gespeicherten Daten werden mittels einer Sendeeinheit 5 zu einer Empfangseinheit 6 gesendet. Anschließend werden die übertragenen Daten ausgewertet.The data stored in the receiver 4 are sent by means of a transmitting unit 5 to a receiving unit 6. Subsequently, the transmitted data are evaluated.

Die Auswertung der Daten erfolgt dadurch, dass ein Vergleich der Anzahl der über dem Schwellenwert liegenden Relativbewegungen mit zumindest einem vorher festgelegten Grenzwert erfolgt.The evaluation of the data is carried out by comparing the number of relative movements above the threshold with at least one predetermined threshold.

Diese Auswertung der Daten erfolgt nach jeweils im Wesentlichen gleichlangen Zeitintervallen oder nach jeweils im Wesentlichen gleicher Kilometerleistung des Koppelelements 1, beispielsweise in einem in FIG 3 dargestellten Fahrzeug 7. Es gilt die Annahme, dass innerhalb dieser gleichlangen Zeitintervalle beziehungsweise nach jeweils gleichen Kilometerleistungen des Fahrzeugs 7 die auf das Koppelelement 1 einwirkenden Kräfte im Mittel gleich groß sind. Ergibt der Vergleich, dass die Anzahl der über dem Schwellenwert liegenden Relativbewegungen des Koppelelements 1 den Grenzwert übersteigt, so wird ein Revisionszeitpunkt für das Fahrzeug 7 festgelegt. Mittels der Auswertung der gespeicherten Relativbewegungen des zu überwachenden Koppelelements 1 erfolgt auch eine Analyse der Betriebsart des in FIG 3 dargestellten Fahrzeugs 7, insbesondere hinsichtlich betriebsorientierter Belastungen des Koppelements 1.This evaluation of the data takes place after each time substantially equal time intervals or after each substantially the same mileage of the coupling element 1, for example in an in FIG. 3 It is assumed that within these same time intervals or after each same mileage of the vehicle 7, the forces acting on the coupling element 1 forces are the same on average. If the comparison reveals that the number of relative movements of the coupling element 1 above the threshold exceeds the limit, a revision time for the vehicle 7 is determined. By means of the evaluation of the stored relative movements of the coupling element 1 to be monitored, an analysis of the operating mode of the in FIG. 3 illustrated vehicle 7, in particular with respect to operational loads of the coupling element. 1

Mittels Einbindung der Ergebnisse dieser Analyse bei der Festlegung des Grenzwertes oder des Schwellenwertes kann die Genauigkeit des erfindungsgemäßen Verfahrens laufend verbessert werden. Es kann damit ein lernender Prozess generiert werden. Zusätzlich können die Ergebnisse auch in Neuentwicklungen von Koppelelementen 1 einfließen.By incorporating the results of this analysis in the determination of the limit value or the threshold value, the accuracy of the method according to the invention can be continuously improved. It can thus be used to generate a learning process. In addition, the results can also be incorporated into new developments of coupling elements 1.

FIG 2 zeigt beispielhaft und schematisch ein als Konusfeder ausgeführtes Koppelelement 1. Der Geber 3 ist am Koppelelement 1 angeordnet. Der Nehmer 4 mit der Sendeeinheit 5 ist am Bauteil 9 angeordnet. Der Abstand zwischen dem Geber 3 und dem Nehmer 4 ist entlang der maßgeblichen Relativbewegungsrichtung 2 variierbar. Im Nehmer 4 werden, wie bereits anhand FIG 1 erläutert, die Relativbewegungen des Koppelelements 1 gespeichert, welche von der Sendeeinheit 5 an die Empfangseinheit 6 übertragen werden. FIG. 2 shows by way of example and schematically a running as a cone spring coupling element 1. The encoder 3 is arranged on the coupling element 1. The recipient 4 with the transmitting unit 5 is arranged on the component 9. The distance between the transmitter 3 and the slave 4 is variable along the relevant relative direction of movement 2. In the receiver 4 become, as already on basis FIG. 1 explained, the relative movements of the coupling element 1 stored, which are transmitted from the transmitting unit 5 to the receiving unit 6.

FIG 3 zeigt beispielhaft und schematisch die Anwendung des erfindungsgemäßen Verfahrens bei einem als Schienenfahrzeug ausgeführten Fahrzeug 7 mit einer berührungslosen Übertragung der Daten mittels der Sendeeinheiten 5 zur Empfangseinheit 6 während der Fahrt des Schienenfahrzeugs in Fahrtrichtung 8. FIG. 3 shows by way of example and schematically the application of the method according to the invention in a vehicle 7 designed as a rail vehicle with a non-contact transmission of the data by means of the transmitting units 5 to the receiving unit 6 while the rail vehicle is traveling in the direction of travel 8.

Dadurch können Koppelelemente 1 überwacht und ihre Einsatzeignung in einem Fahrzeug 7 bestimmt werden.As a result, coupling elements 1 can be monitored and their suitability for use in a vehicle 7 can be determined.

Die erfindungsgemäße Lösung ist nicht auf die dargestellten Beispiele beschränkt, es sind auch andere Ausführungen denkbar.The solution according to the invention is not limited to the illustrated examples, other embodiments are conceivable.
