Description

Technisches Gebiettechnical field

Die Erfindung betrifft eine Spaltüberbrückung für ein Schienenfahrzeug.The invention relates to gap bridging for a rail vehicle.

Eine solche Spaltüberbrückung ist aus der WO2018114588A1 oder aus dem Zwischendokument WO2019096927A1 bekannt.Such a gap bridging is from WO2018114588A1 or from the intermediate document WO2019096927A1 known.

Stand der TechnikState of the art

Die Einstiege von Passagierschienenfahrzeugen sind häufig mit Einrichtungen zur Überbrückung des Spalts zwischen dem Passagierraumboden und dem Bahnsteig ausgestattet. Dabei ist typischerweise eine beweglich gelagerte Trittplatte vorgesehen, welche mit Hilfe eines Kraftantriebs zwischen einer eingefahrenen Position und einer ausgefahrenen Position verschiebbar ist. In Abhängigkeit von der Kinematik der jeweiligen Einrichtung spricht man von Schiebetritten, bei welchen die Trittplatte ähnlich einer Schublade ein- und ausfahrbar ist, oder von Klapp-Schiebetritten, bei welchen die Trittplatte an ihrer dem Bahnsteig zugewandten Kante auch eine Vertikalbewegung ausführt. Diese Spaltüberbrückungen unterliegen der Gefahr der Verschmutzung, welche bei ausschließlich in Tunneln verkehrenden Bahnen zwar reduziert, jedoch trotzdem vorhanden ist. Dadurch ist die Mechanik einer Spaltüberbrückung möglichst verschmutzungstolerant auszuführen, insbesondere weil ein Versagen während des Betriebs weitreichende Folgen bewirkt. Eine Fahrt mit in ausgefahrener Position blockierter Trittplatte ist nicht möglich, sodass eine Reparatur in der Haltestelle und eine Betriebsunterbrechung erforderlich wären. Bekannte Lösungen dieses Problems sehen beispielsweise Bürsten vor, welche an der Trittplatte anhaftenden Schmutz entfernen. Diese Bürsten bedingen jedoch einen beträchtlichen Bauraumbedarf und versagen bei fest anhaftendem Schmutz bzw. Vereisung. Ähnliches gilt auch für die ebenso an dieser Stelle manchmal eingesetzten Gummilippen.The entrances of passenger rail vehicles are often equipped with devices for bridging the gap between the passenger compartment floor and the platform. In this case, a movably mounted footplate is typically provided, which can be displaced between a retracted position and an extended position with the aid of a power drive. Depending on the kinematics of the respective device, one speaks of sliding steps, in which the step plate can be moved in and out like a drawer, or of folding sliding steps, in which the step plate also performs a vertical movement on its edge facing the platform. These gap bridges are subject to the risk of contamination, which is reduced in the case of trains that only run in tunnels, but is nevertheless present. As a result, the mechanics of a gap bridging must be as dirt-tolerant as possible, especially because a failure during operation has far-reaching consequences. It is not possible to drive with the footplate blocked in the extended position, which would require repairs at the bus stop and a service interruption. Known Solutions This problem is provided, for example, by brushes which remove dirt adhering to the treadle. However, these brushes require a considerable amount of space and fail if dirt or icing is firmly adhering to them. The same applies to the rubber lips that are also sometimes used at this point.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt daher die Aufgabe zugrunde, eine Spaltüberbrückung für ein Schienenfahrzeug anzugeben, welche gegen das Eindringen von Schmutz gesichert ist.The invention is therefore based on the object of specifying a gap bridging device for a rail vehicle which is secured against the ingress of dirt.

Die Aufgabe wird durch eine Spaltüberbrückung für ein Schienenfahrzeug mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand untergeordneter Ansprüche.The object is achieved by bridging the gap for a rail vehicle with the features of claim 1. Advantageous configurations are the subject of subordinate claims.

Dem Grundgedanken der Erfindung nach wird eine Spaltüberbrückung für ein Schienenfahrzeug zur Überbrückung des Spalts zwischen einem Bahnsteig und einem Fußboden des Schienenfahrzeugs angegeben, welche eine beweglich gelagerte Trittplatte und eine oberhalb der Trittplatte angeordnete und die Trittplatte zumindest teilweise abdeckende Abdeckplatte umfasst, wobei ein aus Federstahl gefertigtes Abstreifblech vorgesehen ist, welches an einer Unterseite der Abdeckplatte befestigt ist und welches mittels Federkraft in jeder Position der Trittplatte an die Trittplatte angedrückt ist.According to the basic idea of the invention, a gap bridging device for a rail vehicle is specified for bridging the gap between a platform and a floor of the rail vehicle, which comprises a movably mounted footplate and a cover plate which is arranged above the footplate and at least partially covers the footplate, with a made of spring steel Scraper plate is provided, which is attached to an underside of the cover plate and which is pressed by spring force in any position of the footplate on the footplate.

Dadurch ist der Vorteil erzielbar, an der Trittplatte anhaftenden Schmutz sicher und praktisch vollständig bei jedem Einfahrvorgang der Trittplatte entfernen zu können und somit eine Verschmutzung des Inneren der Spaltüberbrückung verhindern zu können.As a result, the advantage can be achieved of being able to remove dirt adhering to the footplate safely and practically completely during each retraction process of the footplate and thus being able to prevent soiling of the interior of the gap bridging.

Besonders vorteilhaft ist dabei, dass die Spaltüberbrückung sowohl als Schiebetritt als auch als Klapp-Schiebetritt ausgeführt sein kann.It is particularly advantageous that the gap bridging can be designed both as a sliding step and as a folding sliding step.

Erfindungsgemäß ist ein aus Federstahl gefertigtes Abstreifblech vorgesehen, welches mittels Federkraft auf die Oberfläche der Trittplatte angedrückt wird. Dabei ist das Abstreifblech so ausgeführt, dass Horizontalkräfte in das Abstreifblech einleitbar sind ohne dass dieses dabei verbogen wird. Dadurch ist sichergestellt, dass auch fest anhaftender Schmutz von der Oberfläche der Trittplatte abgelöst wird. Das Abstreifblech ist dazu fest mit der Abdeckplatte zu verbinden, welche oberhalb der Trittplatte fest angeordnet ist und welche im unmittelbaren Türbereich den Passagierraumboden bildet. Das Abstreifblech ist vorzugsweise als abgekantetes Blech auszuführen, welche eine möglichst eng gebogene Biegekante aufweist, die in eingebautem Zustand auf die Oberfläche der Trittplatte gedrückt wird. Ein weiterer Abschnitt des Abstreifblechs ist möglichst (in eingebautem Zustand) horizontal auszuführen und mit einer Einrichtung zur Befestigung an der Trittplatte auszustatten. Die möglichst horizontale Ausrichtung dieses Abschnitts verhindert das Verbiegen des Abstreifblechs unter Belastung während des Entfernens von Schmutz, insbesondere fest anhaftenden Schmutzes wie an der Oberflächenstruktur der Trittplatte verkeilter Steine.According to the invention, a scraper plate made of spring steel is provided, which is pressed onto the surface of the footplate by means of spring force. The scraper plate is designed in such a way that horizontal forces can be introduced into the scraper plate without it being bent. This ensures that even firmly adhering dirt is removed from the surface of the step plate. For this purpose, the scraper plate is to be firmly connected to the cover plate, which is fixedly arranged above the step plate and which forms the passenger compartment floor in the immediate door area. The scraper plate is preferably designed as a folded plate which has a bending edge which is bent as closely as possible and which is pressed onto the surface of the footplate when installed. Another section of the scraper plate should be as horizontal as possible (when installed) and equipped with a device for fastening to the step plate. The horizontal orientation of this section prevents the scraper plate from bending under load during the removal of dirt, in particular firmly adhering dirt such as stones wedged on the surface structure of the tread plate.

Das Andrücken des Abstreifblechs erfolgt mittels Federkraft, wozu gebräuchliche Blatt- oder Spiralfedern eingesetzt werden können. Erfindungsgemäß wird das Abstreifblech aus Federstahl, vorzugsweise nichtrostendem Federstahl ausgeführt, da solcherart die Andrückkraft durch das Abstreifblech selbst aufgebracht wird und zusätzliche Bauteile wie Federn und zugehörige Befestigungsmittel entfallen können.The scraper plate is pressed on by means of spring force, for which conventional leaf or spiral springs can be used. According to the invention, the scraper plate is made of spring steel, preferably stainless spring steel, since in this way the pressing force is applied by the scraper plate itself and additional Components such as springs and associated fasteners can be omitted.

Die Bemessung der Feder und somit der Federkraft ist in Abhängigkeit von der gewünschten Andrückkraft vorzunehmen. Dabei sind alle möglichen Positionen der beweglichen Trittplatte zu berücksichtigen, insbesondere bei Klapp-Schiebetritten kann die Trittplatte an der Auflagestelle des Abstreifblechs eine Vertikalbewegung von bis zu 10mm ausführen. Dies ist bei der Bemessung der Feder entsprechend zu berücksichtigen, sodass auch bei tiefster Position der Auflagestelle eine hinreichende Andrückkraft gegeben ist. Ebenso ist die Durchbiegung der Abdeckplatte zu berücksichtigen, welche bei maximaler Belastung, beispielsweise durch Passagiere im Türdurchgang typischerweise 3mm betragen kann.The spring and thus the spring force must be dimensioned depending on the desired pressing force. All possible positions of the moveable footplate must be taken into account, especially in the case of folding sliding steps, the footplate can move up to 10mm vertically at the contact point of the scraper plate. This must be taken into account when dimensioning the spring so that there is sufficient pressing force even at the lowest position of the contact point. The deflection of the cover plate must also be taken into account, which can typically amount to 3 mm under maximum load, for example from passengers in the doorway.

Das Abstreifblech ist an der Auflagestelle an der Trittplatte mit eine möglichst eng gebogenen Biegekante auszuführen um zu verhindern, dass anhaftender Schmutz das Abstreifblech anhebt und somit in den zu schützenden Innenbereich der Spaltüberbrückung eindringt.The scraper plate is to be designed with a bending edge that is bent as closely as possible at the contact point on the step plate in order to prevent adhering dirt from lifting the scraper plate and thus penetrating into the inner area of the gap bridging that is to be protected.

Besonders vorteilhaft ist es, das Abstreifblech an der Auflagestelle mit einer Verschleißkante auszustatten, welche lösbar an dem Abstreifblech befestigbar ist und somit bei Beschädigung oder Verschleiß austauschbar ist. Insbesondere vorteilhaft ist es, diese Verschleißkante aus Kunststoff auszuführen, da solcherart eine besonders scharfe (engradige) Kante herstellbar ist, was das Lösen anhaftenden Schmutzes wesentlich verbessert. Da solche scharfen Kanten naturgemäß leichter beschädigt werden, ist die Austauschbarkeit der Verschleißkante ein wesentlicher Vorteil.It is particularly advantageous to equip the scraper plate at the contact point with a wearing edge, which can be detachably fastened to the scraper plate and can therefore be replaced in the event of damage or wear. It is particularly advantageous to make this wearing edge from plastic, since in this way a particularly sharp (narrow) edge can be produced, which significantly improves the loosening of adhering dirt. Since such sharp edges are naturally more easily damaged, the replaceability of the wear edge is a significant advantage.

Zur Verhinderung des Eindringens von Schmutz ist es vorteilhaft, das Abstreifblech gegenüber der Abdeckplatte abzudichten. Dazu kann das Abstreifblech an seinem bahnsteigseitigen Ende mit einem nach oben gebogenen Abschnitt ausgestattet werden, welcher an einer Fläche der Abdeckplatte geführt ist. Dabei ist eine vertikal orientierte Fläche an der Abdeckplatte vorzusehen, was bei typischen Abdeckplatten ohnedies gegeben ist und diese Fläche vorzugsweise reibungsminimierende Auflagen, beispielsweise aus Kunststoff vorzusehen. Dadurch kann verhindert werden, dass Schmutz über die vordere Kante des Abstreifblechs weiter in das Innere der Spaltüberbrückung eintreten.To prevent dirt from penetrating, it is advantageous to seal the wiper plate relative to the cover plate. For this purpose, the scraper plate can be equipped at its platform-side end with a section bent upwards, which is guided on a surface of the cover plate. A vertically oriented surface is to be provided on the cover plate, which is already the case with typical cover plates, and this surface is preferably provided with friction-minimizing supports, for example made of plastic. This can prevent dirt from entering further into the interior of the gap bridging via the front edge of the scraper plate.

Eine weitere, verbesserte Lösung für das Problem der Abdichtung an der vorderen Kante des Abstreifblechs sieht ein Gummiprofil vor, welches an der Unterseite der Abdeckplatte befestigt ist und welches Ausnehmungen aufweist in welche das Abstreifblech eingreift. Solcherart ist eine deutliche Verbesserung der Abdichtung gegeben, da die an dieser Stelle unvermeidlichen Montagetoleranzen durch ein Gummiprofil wesentlich besser ausgeglichen werden können als bei einen direkten Kontakt des Abstreifblechs mit der Abdeckplatte.A further, improved solution to the problem of sealing at the front edge of the scraper plate provides a rubber profile which is attached to the underside of the cover plate and which has recesses into which the scraper plate engages. In this way there is a clear improvement in the seal, since the assembly tolerances that are unavoidable at this point can be compensated for much better by a rubber profile than with direct contact of the scraper plate with the cover plate.

Eine weitere Verbesserung der Abdichtung ist gegeben, wenn eine Verschleißkante aus Kunststoff vorgesehen ist und diese zum Eingriff in das Gummiprofil ausgebildet ist. Die Verschleißkante aus Kunststoff kann wesentlich besser konstruktiv so bemessen werden, dass eine Verbindung mit dem Gummiprofil hergestellt werden kann als das Abstreifblech selbst.A further improvement of the seal is obtained when a wearing edge made of plastic is provided and this is designed to engage in the rubber profile. The plastic wear edge can be dimensioned much better structurally so that a connection can be made with the rubber profile than the scraper plate itself.

Ausführung der Erfindungimplementation of the invention

Fig.1 zeigt beispielhaft und schematisch eine stark abstrahierte Prinzipdarstellung einer Spaltüberbrückung. Es ist ein Querschnitt durch eine in Form eines Schiebetritts aufgebaute Spaltüberbrückung dargestellt, welche eine durch einen Kraftantrieb 6 mittels einer Schiebelagerung 5 linear verschiebbare Trittplatte 1 aufweist. Die Spaltüberbrückung ist in einer eingebauten Position dargestellt, wobei ein Fußboden 7 und eine Tür 8 eines Schienenfahrzeugs gezeigt sind. Eine Abdeckplatte 2 schließt eben an den Fußboden 7 an und bildet die Türschwelle an diesem Einstiegsbereich. Fig.1 shows an example and a schematic of a highly abstracted schematic representation of a gap bridging. A cross section through a gap bridging constructed in the form of a sliding step is shown, which has a step plate 1 that can be linearly displaced by a power drive 6 by means of a sliding bearing 5 . The gap bridging device is shown in an installed position, showing a floor 7 and a door 8 of a rail vehicle. A cover plate 2 just connects to the floor 7 and forms the door sill at this entrance area.

Unterhalb der Abdeckplatte 2 ist ein Abstreifblech 3 angeordnet und mit der Abdeckplatte 2 mittels einer Befestigung 4 fest verbunden. Das Abstreifblech 3 verläuft in von der Befestigung 4 in Richtung des Ausstiegs, d.h. des Bahnsteigs im Wesentlichen horizontal und weist an seinem bahnsteigseitigen Ende eine engradige, scharfe Biegekante auf. Diese Biegekante ist in Kontakt mit der Oberfläche der Trittplatte 1 und bildet somit die Auflagestelle an welcher bei der Einfahrbewegung der Trittplatte 1 der an der Trittplatte 1 anhaftende Schmutz abgeschabt wird.A scraper plate 3 is arranged below the cover plate 2 and is firmly connected to the cover plate 2 by means of a fastening 4 . The scraper plate 3 runs from the attachment 4 in the direction of the exit, ie the platform, essentially horizontally and has a straight, sharp bending edge at its platform-side end. This bending edge is in contact with the surface of the treadle 1 and thus forms the contact point at which the dirt adhering to the treadle 1 is scraped off during the retraction movement of the treadle 1 .

Fig.2 zeigt beispielhaft und schematisch eine Spaltüberbrückung in einer Ausführung als Klapp-Schiebetritt. Es ist eine Ausführung einer Spaltüberbrückung in Form eines Klapp-Schiebetritts gezeigt, bei welchem eine Trittplatte 1 sowohl horizontal schiebbar gelagert ist als auch an ihrem bahnsteigseitigem Ende mittels eines Klapphebels an dem Wagenkasten abgestützt ist. Dadurch kann die Belastbarkeit der Trittplatte 1 gegenüber einem Schiebetritt gesteigert werden, jedoch ergibt sich dabei auch eine Vertikalbewegung der Trittplatte 1 während der Ein- bzw. Ausfahrbewegung. Eine Abdeckplatte 2 ist wie in der Prinzipdarstellung in Fig.1 oberhalb der Trittplatte 1 angeordnet, ein Abstreifblech 3 ist mittels einer Befestigung 4 an der Unterseite der Abdeckplatte 2 fest mit dieser verbunden. Die Form des Abstreifblechs 3 ist sehr ähnlich wie in der Prinzipdarstellung in Fig.1 gezeigt, jedoch weist es an seinem bahnsteigseitigen Ende einen vertikalen Abschnitt auf, welcher an einer ebenfalls vertikal orientierten Fläche der Abdeckplatte 2 in Kontakt ist. Dadurch kann der Eintritt von Schmutz unter die Abdeckplatte 2 verhindert werden. Ein Gleitstück 9 ist an der Kontaktfläche zwischen dem Abstreifblech 3 und der Abdeckplatte 2 angeordnet und reduziert die Reibung zwischen diesen Bauteilen. Fig.2 shows an example and schematic of a gap bridging in an embodiment as a folding sliding step. An embodiment of a gap bridging in the form of a folding sliding step is shown, in which a step plate 1 is mounted so that it can be pushed horizontally and is also supported at its platform-side end by means of a folding lever on the car body. As a result, the load-bearing capacity of the step plate 1 can be increased compared to a sliding step, but this also results in a vertical movement of the step plate 1 during the retraction and extension movement. A cover plate 2 is as shown in the schematic diagram in Fig.1 arranged above the tread plate 1, a scraper plate 3 is connected by means of a fastener 4 on the underside of the cover plate 2 with this. The shape of the scraper plate 3 is very similar to that in the schematic diagram in Fig.1 shown, but it has at its end on the platform side a vertical section, which is also vertically oriented surface of the cover plate 2 in contact. This can prevent dirt from entering under the cover plate 2 . A slide 9 is arranged at the contact surface between the scraper plate 3 and the cover plate 2 and reduces the friction between these components.

Fig.3 zeigt beispielhaft und schematisch eine Spaltüberbrückung in einer Ausführung als Klapp-Schiebetritt mit einer Verschleißkante 10 und einem Gummiprofil 12. Es ist im Wesentlichen das Ausführungsbeispiel aus Fig.2 dargestellt, wobei jedoch zusätzlich eine Verschleißkante 10 an der Auflagestelle angeordnet ist, sodass das Abstreifblech 3 selbst nicht in Kontakt mit der Oberfläche der Trittplatte 1 kommt. Die Verschleißkante 10 ist mittels einer Befestigung 11 an dem Abstreifblech 3 befestigt, wobei vorzugsweise eine lösbare Befestigungsart gewählt ist. Weiters weist die Verschleißkante 10 eine Ausformung in Richtung der Abdeckplatte 2 auf, welche zum Eingriff in ein Gummiprofil 12 ausgeführt ist. Das Gummiprofil 12 ist in einer Ausnehmung der Abdeckplatte 2 befestigt und dichtet zwischen der Abdeckplatte 2 und dem Abstreifblech 3 gegen den Eintritt von Schmutz ab. Der Einsatz eines Gummiprofils 12 an dieser Stelle erlaubt eine wesentlich vereinfachte Montage der Spaltüberbrückung, da die Bauteiltoleranzen dadurch keinen wesentlichen Einfluß auf die Abdichtung zwischen der Abdeckplatte 2 und dem Abstreifblech 3 haben. Fig.3 shows, by way of example and schematically, a gap bridging in the form of a folding sliding step with a wear edge 10 and a rubber profile 12. It is essentially the exemplary embodiment from FIG Fig.2 shown, but in addition a wear edge 10 is arranged at the contact point, so that the scraper plate 3 itself does not come into contact with the surface of the tread plate 1. The wear edge 10 is attached to the scraper plate 3 by means of an attachment 11, preferably one detachable type of attachment is selected. Furthermore, the wear edge 10 has a formation in the direction of the cover plate 2, which is designed to engage in a rubber profile 12. The rubber profile 12 is fastened in a recess in the cover plate 2 and seals between the cover plate 2 and the wiper plate 3 against the ingress of dirt. The use of a rubber profile 12 at this point allows a significantly simplified assembly of the gap bridging, since the component tolerances have no significant influence on the seal between the cover plate 2 and the scraper plate 3.
