Description

Schienenfahrzeug mit einer Schneeschutz-Anordnung für einen Kupplungsbereich des SchienenfahrzeugsRail vehicle with a snow protection arrangement for a coupling area of the rail vehicle

Die Erfindung betrifft ein Schienenfahrzeug, das in Gegenden mit Schnee verkehrt.The invention relates to a rail vehicle that runs in snowy areas.

Je nach Fahrtrichtung, Geschwindigkeit, Schneeaufkommen, Schneebeschaffenheit, usw., kann es zur Anlagerung bzw. zur Ansammlung von Schnee am Schienenfahrzeug kommen. Ein kritischer Bereich für derartige Schneeanlagerungen ist der Bereich um die Kupplung an der Frontseite des Schienenfahrzeugs. Die dort angeordnete Kupplung ist zur Ankupplung weiterer Schienenfahrzeuge (z.B. zur Kupplung mit einem Triebfahrzeug eines weiteren Schienenfahrzeug-Gespanns) ausgebildet und wird entsprechend benutzt.Depending on the direction of travel, speed, amount of snow, nature of the snow, etc., snow can accumulate on the rail vehicle. A critical area for such snow deposits is the area around the coupling at the front of the rail vehicle. The coupling arranged there is designed for coupling other rail vehicles (e.g. for coupling to a traction vehicle of another rail vehicle combination) and is used accordingly.

Abhängig vom Fahrzeugüberhang, von der Fahrzeuglänge und vom Drehgestell-Abstand müssen Kupplungen in bestimmten Bereichen horizontal und vertikal verschwenkbar sein, um den Kupplungsvorgang zu ermöglichen bzw. um in Kurven und Weichenbereichen verkehren zu können.Depending on the vehicle overhang, the vehicle length and the distance between the bogies, couplings must be able to pivot horizontally and vertically in certain areas in order to enable the coupling process or to be able to operate in curves and switch areas.

Daraus ergeben sich trichterförmige Öffnungen um die Kupplung herum, die geradezu prädestiniert dafür sind, mit Schnee aufgefüllt zu werden.This results in funnel-shaped openings around the coupling, which are almost predestined to be filled with snow.

Bei Extrembedingungen führt dieses Auffüllen mit Schnee dazu, dass sich die Kupplung nicht mehr bewegen kann. Dies kann zu betriebskritischen und in seltenen Fällen sogar zu sicherheitsrelevanten Einschränkungen beim Betrieb des Schienenfahrzeugs führen.In extreme conditions, this filling with snow means that the clutch can no longer move. This can lead to operation-critical and, in rare cases, even to safety-related restrictions when operating the rail vehicle.

FIG 5 und FIG 6 zeigen jeweils ein Schienenfahrzeug SFZ6, SFZ7 mit Kupplungen KUP6, KUP7 sowie mit Kupplungsbereichen KUPB6, KUPB7, die vollkommen eingeschneit bzw. vereist sind. 5 and 6 each show a rail vehicle SFZ6, SFZ7 with couplings KUP6, KUP7 and with coupling areas KUPB6, KUPB7 that are completely snowed in or iced over.

Es ist zu vermuten, dass diese Schienenfahrzeuge SFZ6, SFZ7 nicht mehr einsatztauglich sind.It can be assumed that these rail vehicles SFZ6, SFZ7 are no longer fit for use.

Es sind Ausgestaltungen bekannt, mit denen diesem Vereisungs- bzw. Schneeproblem im Kupplungsbereich begegnet wird.Designs are known with which this problem of icing or snow in the area of the clutch is counteracted.

FIG 7 zeigt eine erste Ausgestaltung bei einer amerikanischen Lokomotive als Schienenfahrzeug SFZ8. FIG 7 shows a first embodiment of an American locomotive as a rail vehicle SFZ8.

Dieses ist im Kupplungsbereich KUPB8 derart konzipiert, dass die zugehörige Kupplung KUP8 sehr kurz ausgestaltet ist. Zusätzlich werden durch das Konzept benötigte Schwenkwinkel der Kupplung KUP8 minimiert. Ausschlaggebend für ein solches Fahrzeugkonzept sind die Parameter Länge, Drehgestell-Abstand und Fahrzeugüberhang des Schienenfahrzeugs SFZ8. Werden diese Parameter günstig gewählt, kann die Kupplung KUP8 mit einer geringen Länge und mit geringen Schwenkwinkeln in horizontaler und vertikaler Richtung realisiert werden.This is designed in the clutch area KUPB8 in such a way that the associated clutch KUP8 is designed to be very short. In addition, the required pivoting angles of the KUP8 coupling are minimized by the concept. The parameters length, bogie spacing and vehicle overhang of the SFZ8 rail vehicle are decisive for such a vehicle concept. If these parameters are chosen well, the KUP8 coupling can be realized with a short length and with small swing angles in the horizontal and vertical direction.

FIG 8 zeigt eine zweite Ausgestaltung bei einem deutschen Intercity ICE als Schienenfahrzeug SFZ9. 8 shows a second embodiment of a German Intercity ICE as a rail vehicle SFZ9.

Das Schienenfahrzeug SFZ9 ist im Kupplungsbereich KUPB9 mit einer kurzen Kupplung (hier verdeckt) und mit einer geringen Frontöffnung FROE9 konzipiert. Diese Ausgestaltung ist aufwändig, da eine Konstruktion mit Frontklappen FKL9 benötigt wird, um das Eindringen von Schnee im Kupplungsbereich KUPB9 zu reduzieren bzw. gänzlich zu verhindern. Diese Ausgestaltung wird insbesondere bei Hochgeschwindigkeitszügen eingesetzt, da hier die Frontklappenkonstruktion Vorteile hinsichtlich des Schnees und zusätzlich hinsichtlich der Aerodynamik bietet.The rail vehicle SFZ9 is designed in the coupling area KUPB9 with a short coupling (concealed here) and with a small front opening FROE9. This configuration is complex, since a construction with front flaps FKL9 is required in order to reduce or entirely prevent the penetration of snow in the coupling area KUPB9. This configuration is used in particular in high-speed trains, since here the front flap construction offers advantages in terms of snow and also in terms of aerodynamics.

FIG 9 zeigt eine dritte Ausgestaltung bei einem Triebfahrzeug bzw. Schienenfahrzeug SFZ10 einer deutschen Stadtbahn. 9 shows a third embodiment of a traction vehicle or rail vehicle SFZ10 of a German city railway.

Das Schienenfahrzeug SFZ 10 verfügt im Kupplungsbereich KUPB10 über ein manuell entfernbares Schneeschutzsystem, das hier als Abdeckhaube AH10 ausgebildet ist. Die Abdeckhaube AH10 wird über die Kupplung KUP10 gestülpt und deckt diese dann zumindest teilweise ab. Eine derartige Abdeckhaube AH10 ist beispielsweise aus einem starken, d.h. mechanisch belastbaren, Planen-Stoff gefertigt, wie er auch im Bereich der Lastkraftwagen zur Ladungsabdeckung verwendet wird.The rail vehicle SFZ 10 has a manually removable snow protection system in the coupling area KUPB10, which is designed here as a cover hood AH10. The cover hood AH10 is slipped over the coupling KUP10 and then covers it at least partially. Such a cover AH10 is, for example, made of a strong, ie mechanically resilient, tarpaulin material, as is also used in trucks to cover loads.

Ein derartiges Schneeschutzsystem ist sehr kostengünstig, benötigt jedoch für die Montage bzw. für die Demontage Zeit und manuelle Arbeit von Bedienpersonal beim Kuppelvorgang.Such a snow protection system is very cost-effective, but requires time and manual labor for assembly and disassembly by operating personnel during the coupling process.

Zudem verhindert eine solche Schneeschutzmaßnahme nicht immer das Eindringen von Schnee in den Schwenkbereich der Kupplung.In addition, such a snow protection measure does not always prevent snow from penetrating into the pivoting area of the coupling.

FIG 10 und FIG 11 zeigen Details einer Kupplungssituation an einem weiteren Schienenfahrzeug SFZ11. 10 and 11 show details of a coupling situation on another rail vehicle SFZ11.

Dabei ist in FIG 10 ein Kupplungsbereich KUPB11 detailliert zu sehen, der mit Schnee aufgefüllt und damit zugesetzt werden kann. Zu sehen ist weiterhin ein Kupplungsgelenk KUPG11, das im Kupplungsbereich KUPB11 angeordnet ist und mit der Kupplung KUP11 aus FIG 11 zusammenwirkt.where is in 10 a clutch area KUPB11 can be seen in detail, which can be filled with snow and thus clogged. You can also see a coupling joint KUPG11, which is arranged in the coupling area KUPB11 and is connected to the coupling KUP11 11 works together.

Entsprechend ist in FIG 11 die Kupplung KUP11 sowie das Kupplungsgelenk KUPG11 dargestellt.Correspondingly, in 11 the coupling KUP11 and the coupling joint KUPG11 are shown.

Aus der Druckschrift DE 10 2015 214 606 A1 ist ein Bugklappenmodul für ein Fahrzeug bekannt. Das Bugklappenmodul sieht einen Kupplungsschacht, eine im Kupplungsschacht aufgenommene Kupplungsvorrichtung und mindestens eine unter Verwendung einer Bugklappen-Kinematik bewegbare, den Kupplungsschacht zumindest teilweise abdeckbare Bugklappe vor. Um den Kupplungsschacht bzw. die Kupplungsvorrichtung bei geöffneter Bugklappe vor Umgebungseinflüssen zu schützen, ist bei dem Bugklappenmodul eine am Kupplungsschacht angeordnete Abdeckvorrichtung mit einer Verkleidung vorgesehen, die einerseits am Kupplungsschacht und andererseits an der Kupplungsvorrichtung lösbar befestigt ist.From the pamphlet DE 10 2015 214 606 A1 a front flap module for a vehicle is known. The front flap module provides a coupling shaft, a coupling device accommodated in the coupling shaft and at least one front flap which can be moved using front flap kinematics and can at least partially cover the coupling shaft. In order to protect the coupling shaft or the coupling device from environmental influences when the front hatch is open, the front hatch module is provided with a covering device arranged on the coupling shaft and having a covering which is detachably fastened to the coupling shaft on the one hand and to the coupling device on the other hand.

Es ist die Aufgabe der vorliegenden Erfindung, eine vorteilhafte Schneeschutz-Anordnung für Kupplungsbereiche eines Schienenfahrzeugs anzugeben.It is the object of the present invention to specify an advantageous snow protection arrangement for the coupling areas of a rail vehicle.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This object is solved by the features of claim 1. Advantageous developments are specified in the dependent claims.

Die Erfindung betrifft ein Schienenfahrzeug mit den Merkmalen des Anspruchs 1.The invention relates to a rail vehicle having the features of claim 1.

Die Kupplung ist derart ausgebildet, dass das Schienenfahrzeug über die Kupplung mit einer entsprechend ausgestalteten Kupplung eines weiteren Schienenfahrzeugs verbindbar ist.The coupling is designed in such a way that the rail vehicle can be connected via the coupling to a correspondingly designed coupling of another rail vehicle.

Die Kupplung ist bevorzugt innerhalb der Einbuchtung beweglich gelagert, so dass für den Zweck des Kupplungsvorgangs bzw. für den Zweck des Befahrens von Kurven und Weichenbereichen mit dem weiteren Schienenfahrzeug die Kupplung in einem vorgegebenen Winkelbereich horizontal und vertikal verschwenkbar ist.The coupling is preferably movably mounted within the indentation, so that the coupling can be pivoted horizontally and vertically in a predetermined angular range for the purpose of the coupling process or for the purpose of negotiating curves and switch areas with the other rail vehicle.

Die Kupplung weist damit für den Kupplungsvorgang und im Betrieb der verbundenen Schienenfahrzeuge jeweilige Winkelstellungen auf.The coupling thus has respective angular positions for the coupling process and during operation of the connected rail vehicles.

Die Einbuchtung ist durch eine feste Einhausung zumindest teilweise umfasst. Die Kupplung wird im Bereich der Einbuchtung über die feste Einhausung geschützt.The indentation is at least partially surrounded by a fixed housing. The coupling is protected in the indentation area by the fixed housing.

Die Öffnung der festen Einhausung ist umlaufend mit einem Dichtungselement, dem ersten Dichtungselement, fest verbunden, so dass über die Verbindung das Dichtungselement ebenfalls fest bzw. starr ist.The opening of the fixed housing is firmly connected circumferentially to a sealing element, the first sealing element, so that the sealing element is also fixed or rigid via the connection.

Das erste Dichtungselement weist einen schneedichten Übergang zur Einhausung auf.The first sealing element has a snow-tight transition to the housing.

Das erste Dichtungselement ist als Dichtungselement der Einhausung bevorzugt aus einem flexiblen Gummi gefertigt.As the sealing element of the housing, the first sealing element is preferably made of flexible rubber.

Das Dichtungselement der Einhausung ist bevorzugt als Hohlkammerprofil bzw. als Wulst ausgestaltet.The sealing element of the housing is preferably designed as a hollow chamber profile or as a bead.

Die Kupplung ist mit einem zweiten Dichtungselement verbunden, das die Kupplung zumindest teilweise umgibt.The coupling is connected to a second sealing element that at least partially surrounds the coupling.

Das zweite Dichtungselement weist einen schneedichten Übergang zur Kupplung auf.The second sealing element has a snow-tight transition to the clutch.

Das zweite Dichtungselement ist als Dichtungselement der Kupplung drehbar mit der Kupplung verbunden, wobei diese Verbindung bevorzugt als Drehgelenk ausgestaltet ist.As the sealing element of the coupling, the second sealing element is rotatably connected to the coupling, this connection preferably being designed as a swivel joint.

Durch die Drehbarkeit des zweiten Dichtungselements sowie durch die Positionen und Formen der beiden Dichtungselemente wird bewirkt, dass bei unterschiedlichen Winkelstellungen der Kupplung das Dichtungselement der Kupplung durch Druckeinwirkung stets mit dem Dichtungselement der Einhausung gekoppelt ist.The rotatability of the second sealing element and the positions and shapes of the two sealing elements ensure that the sealing element of the coupling is always coupled to the sealing element of the housing when the coupling is in different angular positions.

Das zweite Dichtungselement ist bevorzugt als Hohlkammerprofil bzw. als Wulst ausgestaltet.The second sealing element is preferably designed as a hollow chamber profile or as a bead.

Die beiden Dichtungselemente überlappen einander zumindest teilweise und liegen beweglich aneinander an. Durch ihre jeweiligen Positionen werden die beiden Dichtungselemente aufeinandergedrückt.The two sealing elements at least partially overlap and are movably in contact with one another. The two sealing elements are pressed against one another by their respective positions.

Bevorzugt wird zwischen den beiden Dichtungselementen ein Reibschluss realisiert.A frictional connection is preferably implemented between the two sealing elements.

Das zweite Dichtungselement ist bevorzugt aus einem flexiblen Gummi gefertigt.The second sealing element is preferably made of a flexible rubber.

Durch die Hohlkammern bzw. Wülste wird eine zusätzliche Flexibilität der Dichtungselemente realisiert und der gewünschte Reibschluss unterstützt.Additional flexibility of the sealing elements is realized by the hollow chambers or beads and the desired frictional connection is supported.

In einer bevorzugten Weiterbildung weist das zweite Dichtungselement flexible Manschetten auf, die im Bereich um die Kupplung herum angeordnet sind und diesen Bereich zusätzlich abdichten.In a preferred development, the second sealing element has flexible collars which are arranged in the area around the coupling and additionally seal this area.

Diese flexiblen Manschetten sind bevorzugt aus Gummi gefertigt.These flexible cuffs are preferably made of rubber.

Durch die beiden Dichtungselemente wird eine Abdichtung der Öffnung gegen Schnee erreicht, die bei jeder Bewegung der Kupplung zuverlässig funktioniert.The two sealing elements seal the opening against snow, which works reliably with every movement of the coupling.

Translatorische Bewegungen der gekuppelten Schienenfahrzeuge werden in Richtung der Längsachse der Schienenfahrzeuge durch ein Eindrücken der Hohlkammerprofile bzw. der Wülste bei gleichzeitiger Abdichtung aufgenommen.Translational movements of the coupled rail vehicles are absorbed in the direction of the longitudinal axis of the rail vehicles by pressing in the hollow chamber profiles or the beads with simultaneous sealing.

Bei lateralen Bewegungen quer zur Längsachse gleiten die Hohlkammerprofile bzw. Wülste aufeinander und nehmen damit diese Bewegungen bei gleichzeitiger Abdichtung auf.In the event of lateral movements transverse to the longitudinal axis, the hollow chamber profiles or beads slide on top of each other and thus absorb these movements while at the same time sealing.

Bei Winkelbewegungen (Rollen, Gieren, Wanken) der verbundenen Schienenfahrzeuge zueinander werden die Hohlkammerprofile bzw. Wülste unterschiedlich stark eingedrückt. Dadurch werden alle auftretenden Relativbewegungen bei gleichzeitiger Abdichtung aufgenommen.In the case of angular movements (rolling, yawing, rolling) of the connected rail vehicles relative to one another, the hollow chamber profiles or beads are pressed in to different extents. As a result, all relative movements that occur are absorbed while sealing at the same time.

Die erfindungsgemäße Anordnung ist mit kostengünstig und mit geringem Aufwand sowohl realisierbar als auch nachrüstbar.The arrangement according to the invention can be both implemented and retrofitted at low cost and with little effort.

Durch die erfindungsgemäße Anordnung wird gewährleistet, dass die Einsatzbereitschaft von Schienenfahrzeugen in strengen Wintermonaten erhöht wird ohne manuelle Handgriffe zu benötigen.The arrangement according to the invention ensures that the operational readiness of rail vehicles is increased in the harsh winter months without requiring any manual intervention.

Bislang bei Schneefall benötigte Kuppelzeiten von Schienenfahrzeugen, die aufgrund von manueller Arbeit von Eisenbahnpersonal entstehen, werden reduziert.Previously required coupling times of rail vehicles during snowfall, which arise due to manual work by railway personnel, are reduced.

Durch die erfindungsgemäße Anordnung werden Ausfallzeiten von Schienenfahrzeugen reduziert, die durch von Schnee blockierten Kupplungen bedingt werden.The arrangement according to the invention reduces downtimes of rail vehicles that are caused by couplings blocked by snow.

Nachfolgend wird die vorliegende Erfindung beispielhaft anhand einer Zeichnung näher erläutert.The present invention is explained in more detail below by way of example with reference to a drawing.

Eine feste Einhausung EINH umfasst die Einbuchtung EINE zumindest teilweise. Die Einhausung EINH weist in Fahrtrichtung des Schienenfahrzeugs SFZ eine Öffnung OFF auf, aus der die Kupplung KUP in einer vorgegebenen Winkelstellung teilweise herausragt, um einen Kupplungsvorgang mit einem weiteren Schienenfahrzeug zu ermöglichen.A fixed enclosure EINH at least partially encompasses the indentation EINE. The housing EINH has an opening OFF in the direction of travel of the rail vehicle SFZ, from which the coupling KUP partially protrudes in a predetermined angular position in order to enable a coupling process with another rail vehicle.

Die Öffnung OFF der festen Einhausung EINH ist umlaufend mit einem ersten Dichtungselement DIE1 fest verbunden.The opening OFF of the fixed housing EINH is firmly connected all the way around to a first sealing element DIE1.

In diesem Beispiel ist das erste Dichtungselement DIE1 als flexibles Hohlkammerprofil ausgestaltet.In this example, the first sealing element DIE1 is designed as a flexible hollow chamber profile.

Die Größe der Öffnung OFF ist so dimensioniert, dass die Kupplung KUP alle Bewegungen, die aus dem Betrieb entstehen, durchführen kann.The size of the OFF opening is dimensioned in such a way that the KUP clutch can carry out all movements arising from operation.

Die Einhausung EINH ist fest mit der Front des Schienenfahrzeugs SFZ verbunden und kann sich gegenüber dem Schienenfahrzeug nicht bewegen.The housing EINH is permanently connected to the front of the rail vehicle SFZ and cannot move relative to the rail vehicle.

Auch die Öffnung OFF samt umlaufendem Dichtungselement DIE1 ist so dimensioniert, dass die Kupplung KUP alle notwendigen Bewegungen im Betrieb durchführen kann.The OFF opening, together with the surrounding sealing element DIE1, is also dimensioned in such a way that the KUP coupling can carry out all the necessary movements during operation.

Das zweite Dichtungselement DIE2 ist durch ein Drehgelenk DRG mit der Kupplung KUP verbunden.The second sealing element DIE2 is connected to the clutch KUP by a rotary joint DRG.

Zusätzlich weist das zweite Dichtungselement DIE2 flexible Manschetten FMS auf, die im Bereich um die Kupplung KUP herum angeordnet sind und den Übergang zur Kupplung KUP zusätzlich abdichten.In addition, the second sealing element DIE2 has flexible collars FMS, which are arranged in the area around the clutch KUP and additionally seal the transition to the clutch KUP.

Die flexiblen Manschetten FMS weisen umlaufend einen Rahmen FMSR auf, über den sie mit dem Hohlkammerprofil verbunden sind.The flexible sleeves FMS have a frame FMSR all around, which is used to connect them to the hollow chamber profile.

Ebenfalls zu sehen ist ein Kupplungsgelenk KUPG, über das die Kupplung KUP in der Einbuchtung EINE des Schienenfahrzeugs SFZ über ein Gelenk befestigt ist. Über dieses Gelenk (vgl. dazu auch das Kupplungsgelenk KUPG11 der FIG 10) ist es möglich, dass die Kupplung KUP zur Durchführung des Kupplungsvorgangs und während der Fahrt von verbundenen Schienenfahrzeugen verschiedene Winkelstellungen einnimmt.A coupling joint KUPG, via which the coupling KUP is fastened in the indentation EINE of the rail vehicle SFZ via a joint, can also be seen. About this joint (see also the coupling joint KUPG11 of 10 ) it is possible that the coupling KUP assumes different angular positions for the execution of the coupling process and while driving connected rail vehicles.

Das drehbar bewegliche zweite Dichtungselement DIE2 bewirkt, dass sich diese bei einer Drehung der Kupplung KUP um eine vertikale Achse immer wieder am ersten Dichtungselement DIE1 ausrichtet.The rotatably movable second sealing element DIE2 causes it to repeatedly align itself with the first sealing element DIE1 when the clutch KUP rotates about a vertical axis.

FIG 3 zeigt mit Bezug auf FIG 1 und FIG 2 eine komplette Ansicht der erfindungsgemäßen Anordnung. 3 shows with reference to 1 and 2 a complete view of the arrangement according to the invention.

Die beiden Dichtungselemente DIE1, DIE2 überlappen sich im Bereich der Öffnung OFF bei unterschiedlichen Winkelstellungen der Kupplung KUP zumindest teilweise. Die beiden Dichtungselemente DIE1, DIE2 sind durch Druck miteinander gekoppelt und schützen dadurch die Öffnung OFF vor einem Eindringen von Schnee.The two sealing elements DIE1, DIE2 at least partially overlap in the area of the opening OFF with different angular positions of the clutch KUP. The two sealing elements DIE1, DIE2 are coupled to one another by pressure and thereby protect the opening OFF from snow penetrating.

Das drehbar bewegliche zweite Dichtungselement DIE2 bewirkt, dass sich diese bei einer Drehung der Kupplung KUP um eine vertikale Achse immer wieder am ersten Dichtungselement DIE1 Ausrichtet, wobei gleichzeitig die Fähigkeit zur Abdichtung erhalten bleibt.The rotatably movable second sealing element DIE2 causes it to repeatedly align itself with the first sealing element DIE1 when the clutch KUP rotates about a vertical axis, while at the same time the ability to seal is retained.

FIG 4 zeigt mit Bezug auf FIG 1 bis FIG 3 eine vorteilhafte Weiterbildung der erfindungsgemäßen Anordnung. FIG 4 shows with reference to 1 to 3 an advantageous development of the arrangement according to the invention.

Diese Ausgestaltung adressiert den Fall, dass zwei Schienenfahrzeuge, die zueinander in einem engen Gleisbogenstehen, miteinander gekuppelt werden.This embodiment addresses the case where two rail vehicles, which are in a narrow curve of track to one another, are coupled to one another.

Zur Durchführung des Kupplungsvorgangs müsste Betriebspersonal die beiden Dichtungselemente DIE1, DIE2 durch Kraftanwendung verschieben. Sind die beiden Dichtungselemente DIE1, DIE2 beispielswiese aus Gummi gefertigt, könnte es vorkommen, dass die benötigte Kraft durch das Betriebspersonal nicht aufgebracht werden kann.To carry out the coupling process, operating personnel would have to move the two sealing elements DIE1, DIE2 by applying force. If the two sealing elements DIE1, DIE2 are made of rubber, for example, it could happen that the required force cannot be applied by the operating personnel.

Um dieses Problem zu lösen ist das Drehgelenk DRG entlang der Längsachse der Kupplung KUP verschiebbar gelagert.In order to solve this problem, the rotary joint DRG is slidably mounted along the longitudinal axis of the clutch KUP.

Eine Druck- oder Zugfeder FED hält das Drehgelenk DRG in Position und limitiert die Druck- bzw. Anpresskraft der beiden Dichtungselemente DIE1, DIE2.A compression or tension spring FED holds the swivel joint DRG in position and limits the compressive or pressing force of the two sealing elements DIE1, DIE2.

Die beiden Dichtungselemente DIE1, DIE2 sind insbesondere im eingefederten Zustand des zweiten Dichtungselements DIE2 miteinander gekoppelt.The two sealing elements DIE1, DIE2 are coupled to one another, in particular when the second sealing element DIE2 is in the compressed state.
