Spaltüberbrückung für ein Schienenfahrzeug. Gap bridging for a rail vehicle.
Technisches Gebiet Technical field
Die Erfindung betrifft eine Spaltüberbrückung für ein The invention relates to a gap bridging for a
Schienenfahrzeug . Rail vehicle.
Stand der Technik State of the art
Die Einstiege von Passagierschienenfahrzeugen sind häufig mit Einrichtungen zur Überbrückung des Spalts zwischen dem The entrances of passenger rail vehicles are often equipped with devices to bridge the gap between the
Passagierraumboden und dem Bahnsteig ausgestattet. Dabei ist typischerweise eine beweglich gelagerte Trittplatte Passenger compartment floor and the platform. There is typically a movably mounted tread plate
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 provided which can be displaced between a retracted position and an extended position by means of a power drive. Depending on the kinematics of the respective device, one speaks of sliding steps in which the step plate can be extended and retracted like a drawer, or 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 pollution, which
ausschließlich in Tunneln verkehrenden Bahnen zwar reduziert, jedoch trotzdem vorhanden ist. Dadurch ist die Mechanik einer Spaltüberbrückung möglichst verschmutzungstolerant only reduced in trains running in tunnels, but is still there. As a result, the mechanics of gap bridging are as tolerant of contamination as possible
auszuführen, insbesondere weil ein Versagen während des to perform, especially because of failure during the
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. Operational far-reaching consequences. A trip with the tread plate blocked in the extended position is not possible, so that a repair at the stop and an interruption of operation would be necessary. Known solutions This problem is provided, for example, by brushes which remove dirt adhering to the step plate. However, these brushes require a considerable amount of installation space and fail when dirt or icing adheres firmly.
Ähnliches gilt auch für die ebenso an dieser Stelle manchmal eingesetzten Gummilippen. The same applies to the rubber lips that are also sometimes used here.
Darstellung der Erfindung Presentation of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, eine The invention is therefore based on the object
Spaltüberbrückung für ein Schienenfahrzeug anzugeben, welche gegen das Eindringen von Schmutz gesichert ist. Specify gap bridging for a rail vehicle, which is secured against the ingress of dirt.
Die Aufgabe wird durch eine Spaltüberbrückung für ein The task is accomplished by bridging a gap for one
Schienenfahrzeug mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand untergeordneter Ansprüche . Rail vehicle with the features of claim 1 solved. Advantageous refinements are the subject of subordinate claims.
Dem Grundgedanken der Erfindung nach wird eine According to the basic idea of the invention
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 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. Gap bridging for a rail vehicle for bridging the gap between a platform and a floor of the rail vehicle is specified, which comprises a movably mounted tread plate and a cover plate arranged above the tread plate and at least partially covering the tread plate, a wiper plate being provided on a bottom side of the cover plate is attached and which is pressed by spring force in any position of the tread plate on the tread plate.
Dadurch ist der Vorteil erzielbar, an der Trittplatte The advantage can be achieved on the tread plate
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. Besonders vorteilhaft ist dabei, dass die Spaltüberbrückung sowohl als Schiebetritt als auch als Klapp-Schiebetritt ausgeführt sein kann. to be able to remove adhering dirt safely and practically completely with every retraction of the step plate and thus to prevent contamination of the interior of the gap bridging. 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 Abstreifblech vorgesehen, welches mittels Federkraft auf die Oberfläche der Trittplatte According to the invention, a scraper plate is provided, which is applied to the surface of the tread plate by means of spring force
angedrückt wird. Dabei ist das Abstreifblech so ausgeführt, dass Horizontalkräfte in das Abstreifblech einleitbar sind ohne dass dieses dabei verbogen wird. Dadurch ist is pressed. The scraper plate is designed so that horizontal forces can be introduced into the scraper plate without it being bent. This is
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 ensures that even firmly adhering dirt is removed from the surface of the step plate. For this purpose, the scraper plate must be firmly connected to the cover plate, which is arranged above the tread plate and which forms the floor of the passenger compartment in the immediate door area. The scraper plate is preferably a folded sheet
auszuführen, welche eine möglichst eng gebogene Biegekante aufweist, die in eingebautem Zustand auf die Oberfläche der Trittplatte gedrückt wird. Ein weiterer Abschnitt des to execute, which has a bending edge which is as tightly bent as possible and which, in the installed state, is pressed onto the surface of the step plate. Another section of the
Abstreifblechs ist möglichst (in eingebautem Zustand) horizontal auszuführen und mit einer Einrichtung zur Scraper plates should be carried out horizontally (when installed) and with a device for
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 Attachment to the footplate. The orientation of this section as horizontal as possible prevents the wiping plate from bending under load during the removal of dirt, in particular firmly adhering
Schmutzes wie an der Oberflächenstruktur der Trittplatte verkeilter Steine. Dirt like stones wedged on the surface structure of the step plate.
Das Andrücken des Abstreifblechs erfolgt mittels Federkraft, wozu gebräuchliche Blatt- oder Spiralfedern eingesetzt werden können. Besonders vorteilhaft ist es, das Abstreifblech aus Federstahl, vorzugsweise nichtrostendem Federstahl The scraper plate is pressed on using spring force, for which purpose conventional leaf or spiral springs can be used. It, the scraper plate made of spring steel, preferably stainless spring steel, is particularly advantageous
auszuführen, da solcherart die Andrückkraft durch das to perform, as such the pressing force by the
Abstreifblech selbst aufgebracht wird und zusätzliche Bauteile wie Federn und zugehörige Befestigungsmittel Scraper plate itself is applied and additional Components such as springs and associated fasteners
entfallen können. can be omitted.
Die Bemessung der Feder und somit der Federkraft ist in The dimension of the spring and thus the spring force is in
Abhängigkeit von der gewünschten Andrückkraft vorzunehmen. Dabei sind alle möglichen Positionen der beweglichen Depending on the desired pressing force. All possible positions are movable
Trittplatte zu berücksichtigen, insbesondere bei Klapp- Schiebetritten kann die Trittplatte an der Auflagestelle des Abstreifblechs eine Vertikalbewegung von bis zu 10mm Footplate to be taken into account, especially with folding and sliding steps, the footplate can have a vertical movement of up to 10mm at the contact point of the scraper plate
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 To run. This must be taken into account when dimensioning the spring, so that there is sufficient pressure even when the support is in the lowest position. The deflection of the cover plate is also too
berücksichtigen, welche bei maximaler Belastung, take into account which at maximum load,
beispielsweise durch Passagiere im Türdurchgang for example by passengers in the doorway
typischerweise 3mm betragen kann. typically can be 3mm.
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 The scraper plate is to be carried out at the contact point on the tread plate with a bending edge that is as tightly bent as possible in order to prevent adhering dirt from lifting up the scraper plate and thus into the interior area to be protected
Spaltüberbrückung eindringt. Gap bridging penetrates.
Besonders vorteilhaft ist es, das Abstreifblech an der  It, the scraper plate on the
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. Zur Verhinderung des Eindringens von Schmutz ist es To provide the support point with a wear edge, which can be detachably attached to the scraper plate and can therefore be replaced in the event of damage or wear. It is particularly advantageous to carry out this wear edge made of plastic, since a particularly sharp (narrow) edge can be produced in this way, which significantly improves the loosening of adhering dirt. Since such sharp edges are naturally more easily damaged, the interchangeability of the wear edge is a major advantage. It is to prevent dirt from entering
vorteilhaft, das Abstreifblech gegenüber der Abdeckplatte abzudichten. Dazu kann das Abstreifblech an seinem advantageous to seal the scraper plate against the cover plate. For this purpose, the scraper plate on his
bahnsteigseitigen Ende mit einem nach oben gebogenen Platform-side end with an upward bent
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 Section are equipped, which is guided on a surface of the cover plate. A vertically oriented surface must be provided on the cover plate, which is the case with typical cover plates anyway, and this surface
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. preferably to provide friction-minimizing pads, for example made of plastic. This can prevent dirt from entering the interior of the gap bridging further via the front edge of the scraper plate.
Eine weitere, verbesserte Lösung für das Problem der  Another improved solution to the problem of
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 Sealing on 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. Such is a clear one
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. Improvement of the seal given that the inevitable assembly tolerances can be compensated for much better with a rubber profile than with a 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 A further improvement of the seal is given if a wear edge made of plastic is provided and this is designed to engage the rubber profile. The
Verschleißkante aus Kunststoff kann wesentlich besser Wear edge made of plastic can do much better

A cross section is shown through a gap bridging constructed in the form of a sliding step, which has a tread plate 1 which can be moved linearly by means of a power drive 6 by means of a sliding bearing 5. The gap bridging is shown in an installed position, with a floor 7 and a door 8 of a rail vehicle being shown. A cover plate 2 just connects to the floor 7 and forms the threshold at this entry area.
Unterhalb der Abdeckplatte 2 ist ein Abstreifblech 3 Below the cover plate 2 is a scraper plate 3
angeordnet und mit der Abdeckplatte 2 mittels einer arranged and with the cover plate 2 by means of a
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 Attachment 4 firmly connected. The scraper plate 3 runs from the attachment 4 in the direction of the exit, i.e. of the platform is essentially horizontal and has a narrow, sharp bending edge at its end on the platform side. This bending edge is in contact with the surface of the tread plate 1 and thus forms the support point at which during the retracting movement of the tread plate 1 the at the

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.l oberhalb der Trittplatte 1 angeordnet, ein Abstreifblech 3 ist mittels einer Befestigung 4 an der Unterseite der Car body is supported. As a result, the resilience 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 retracting or extending movement. A cover plate 2 is arranged as in the basic illustration in Fig.l above the tread plate 1, a scraper plate 3 is by means of a fastening 4 on the underside of the
