Description

Die Erfindung betrifft eine Verbindungseinrichtung zur Verbindung von Wagenkästen eines Schienenfahrzeugs sowie einen Wagenkasten umfassend ein Wagenkastengehäuse und mindestens eine mit dem Wagenkastengehäuse verbundene derartige Verbindungseinrichtung nach dem Oberbegriff von Anspruch 1.The invention relates to a connecting device for connecting car bodies of a rail vehicle and a car body comprising a car body housing and at least one such connecting device connected to the car body housing according to the preamble of claim 1.

Eine solche Verbindungseinrichtung ist beispielsweise aus der WO 2015/096893 A1 , der EP 3 072 773 A1 oder der EP 2 845 784 A1 bekannt.Such a connection device is, for example, from WO 2015/096893 A1 , the EP 3 072 773 A1 or the EP 2 845 784 A1 known.

Derartige Verbindungseinrichtungen dienen der Befestigung von Komponenten (z. B. kurze Wagenkästen oder Wagenkastenkomponenten) eines Schienenfahrzeugs, die in Längsrichtung zwischen den beiden angrenzenden Wagenkästen angeordnet sind, zu diesen beiden jedoch aufgrund der während des normalen Fahrbetriebs, etwa bei Kurvenfahrten, auftretenden Relativbewegungen beabstandet bleiben müssen.Such connecting devices are used to attach components (e.g. short car bodies or car body components) of a rail vehicle, which are arranged in the longitudinal direction between the two adjacent car bodies, but remain spaced apart from these two due to the relative movements that occur during normal driving operation, for example when cornering must.

Die Längsrichtung bezeichnet hier und im Rest der Anmeldung die Richtung entlang der Schienen bzw. die Bewegungsrichtung des Schienenfahrzeugs. Entsprechend bezeichnet die Querrichtung die Richtungen senkrecht zur Längsrichtung.Here and in the rest of the application, the longitudinal direction designates the direction along the rails or the direction of movement of the rail vehicle. Correspondingly, the transverse direction designates the directions perpendicular to the longitudinal direction.

Es ist üblich, den gesamten zwischen den Wagenkästen verfügbaren Weg in Längsrichtung (ausgenommen bei extremen Kurvenfahrten) zu Energieabsorption zu nutzen. Wenn die zwischen den Wagenkästen liegenden Komponenten in Längsrichtung fest an einem der Wagenkästen bzw. Teilen der Verbindungseinrichtung angebunden werden, steht der für die Beweglichkeit vorgehaltene Abstand nicht als Längshub zur Energieabsorption zur Verfügung.It is common practice to use the entire longitudinal path available between the car bodies (except for extreme cornering) for energy absorption. If the components located between the car bodies are firmly connected in the longitudinal direction to one of the car bodies or parts of the connecting device, the distance reserved for mobility is not available as a longitudinal stroke for energy absorption.

Die Energieabsorption bei einer Kollision erfolgt oftmals über separate Federungssysteme, die jedoch schwierig so einzurichten sind, dass sie bei einer bestimmten Druckkraft sofort und kontrolliert Wirkung zeigen. Häufig sind an bekannten Verbindungseinrichtungen (z. B. Kuppelstangen) kleinere Halter für Kabelführungen, Anschlagpuffer, Zentriereinrichtungen oder Übergangsbrücken befestigt. Diese Bauteile widersprechen zwar in ihrer nominalen Lage dem vorgesehenen Hub des Energieabsorbers, sind jedoch in der Festigkeit der Anbindung oder ihrer eigenen Struktur so schwach, dass sie keinen nennenswerten zusätzlichen Widerstand verursachen.Energy absorption in a collision is often provided by separate suspension systems, but these are difficult to set up to have an instantaneous and controlled effect at a given compressive force. Smaller holders for cable guides, stop buffers, centering devices or transition bridges are often attached to known connecting devices (e.g. coupling rods). Although these components contradict the intended stroke of the energy absorber in their nominal position, they are so weak in terms of the strength of the connection or their own structure that they do not cause any additional resistance worth mentioning.

Problematisch hingegen sind Fahrwerke und/oder Wagensegmente von vollem Querschnitt, die aufgrund ihrer Masse und sonstiger einwirkender Kräfte nicht triviale Belastungen auf die Längsanbindung ausüben. Bisher ausgeführte Gliederzüge haben daher für jeden einzelnen Zwischenraum zwischen den Wagenkastensegmenten einen separaten Energieabsorber (NS Sprinter LT, Mireo) bzw. verzichten teilweise (Talent 2, FLIRT) oder vollständig (TGV) auf gezielte Energieabsorption im Zugverband des Schienenfahrzeugs.On the other hand, running gears and/or car segments with a full cross-section are problematic, as they exert non-trivial loads on the longitudinal connection due to their mass and other acting forces. Articulated trains that have been used to date therefore have a separate energy absorber for each individual space between the car body segments (NS Sprinter LT, Mireo) or partially (Talent 2, FLIRT) or completely (TGV) do without targeted energy absorption in the train set of the rail vehicle.

Gerade für kleinere Kollisionen, beispielsweise bei einer Notbremsung eines Güterzugs, ist es jedoch wünschenswert, Schäden auf leicht austauschbare und möglichst wenige Teile eines Wagenkastens zu beschränken, um eine schnelle und kostengünstige Reparatur zu ermöglichen.Especially for minor collisions, for example in the event of an emergency braking of a freight train, it is desirable to limit damage to easily replaceable and as few parts of a car body as possible in order to enable quick and inexpensive repairs.

Die Aufgabe besteht darin, eine Verbindungseinrichtung zur Verbindung von Wagenkästen eines Schienenfahrzeugs mit einer verbesserten Energieabsorption bei einer Kollision zur Verfügung zu stellen.The object is to provide a connecting device for connecting car bodies of a rail vehicle with improved energy absorption in the event of a collision.

Erfindungsgemäß wird eine Verbindungseinrichtung der eingangs genannten Art zur Verfügung gestellt, umfassend:

  • ein Außengehäuse,
  • ein Innengehäuse,
  • einen mit dem Außengehäuse und dem Innengehäuse verbundenen Energieabsorber, und
  • eine Mitnahmeeinrichtung zur Verbindung der Verbindungseinrichtung mit einem Wagenkastengehäuse eines Wagenkastens,
  • wobei das Außengehäuse, das Innengehäuse und der Energieabsorber im Wesentlichen entlang einer gemeinsamen Längsachse angeordnet sind, und
  • wobei die Verbindungseinrichtung dazu eingerichtet ist, Zugkräfte und Druckkräfte entlang der Längsachse zu übertragen, und
  • wobei der Energieabsorber dazu eingerichtet ist, sich bei einem Ãœberschreiten einer vorbestimmten Druckkraft entlang der Längsachse irreversibel zu verformen, sodass sich die Länge der Verbindungseinrichtung entlang der Längsachse reduziert und sich das Innengehäuse teilweise in das Außengehäuse schiebt,
wobei ferner Funktionsflächen zur formschlüssigen Übertragung von Zugkräften zwischen dem Außengehäuse und dem Innengehäuse vorgesehen sind, wobei die Funktionsflächen als Langlöcher im Außengehäuse und im Innengehäuse ausgebildet sind, und wobei die Mitnahmeeinrichtung in beiden Langlöchern in Querrichtung geführt ist.According to the invention, a connecting device of the type mentioned at the outset is provided, comprising:
  • an outer case,
  • an inner case,
  • an energy absorber connected to the outer casing and the inner casing, and
  • a driving device for connecting the connecting device to a car body housing of a car body,
  • wherein the outer housing, the inner housing and the energy absorber are arranged substantially along a common longitudinal axis, and
  • wherein the connecting device is configured to transmit tensile forces and compressive forces along the longitudinal axis, and
  • wherein the energy absorber is set up to deform irreversibly along the longitudinal axis when a predetermined compressive force is exceeded, so that the length of the connecting device is reduced along the longitudinal axis and the inner housing is partially pushed into the outer housing,
functional surfaces for the form-fit transmission of tensile forces between the outer housing and the inner housing being provided, the functional surfaces being designed as elongated holes in the outer housing and in the inner housing, and the entrainment device being guided in both elongated holes in the transverse direction.

Die Wagenkästen mehrgliedriger Schienenfahrzeuge können mit einer solchen Lösung über eine Anordnung von Außengehäuse und Innengehäuse verbunden werden, wobei bei einer Kollision Energie über den Energieabsorber durch irreversible Verformung absorbiert wird. Bei Überschreiten einer vorbestimmten Druckkraft (Ansprechkraft) bewegen sich das Innengehäuse und das Außengehäuse aufeinander zu bzw. ineinander hinein, sodass sich die Länge der Verbindungseinrichtung verkürzt und mittels der durch die dem Energieabsorber aufgeprägten Kraft Energie absorbiert wird. In einem gewissen Rahmen können so die Schäden bei einer Kollision auf die Verbindungseinrichtung begrenzt bleiben, was eine Reparatur deutlich erleichtert. Die Mitnahmeeinrichtung ist als eine formschlüssige Verbindung zur Übertragung von Zugkräften zwischen dem Innengehäuse und dem Außengehäuse vorgesehen. Die Mitnahmeeinrichtung ist vorzugsweise mit dem Innengehäuse und dem Außengehäuse zugfest verbunden, jedoch nicht druckfest verbunden. Die Mitnahmeeinrichtung kann als rotationssymmetrische Hülse ausgebildet sein, die vorzugsweise in Querrichtung verläuft.With such a solution, the car bodies of multi-part rail vehicles can be connected via an arrangement of outer housing and inner housing, with energy being absorbed by the energy absorber by irreversible deformation in the event of a collision. If a predetermined compressive force (response force) is exceeded, the inner housing and the outer housing move towards one another or into one another, so that the length of the connecting device is shortened and energy is absorbed by the force exerted by the energy absorber. To a certain extent, damage in the event of a collision can be limited to the connection device, which makes repairs much easier. The Driving device is provided as a positive connection for the transmission of tensile forces between the inner housing and the outer housing. The entrainment device is preferably connected to the inner housing and the outer housing in a tension-resistant manner, but not in a pressure-resistant manner. The entrainment device can be designed as a rotationally symmetrical sleeve, which preferably runs in the transverse direction.

Die Erfindung nutzt eine Bauform einer energieabsorbierenden Verbindungseinrichtung, bei der der Energieabsorber, der selbst nur Druckkräfte übertragen kann, so zwischen Innengehäuse und Außengehäuse vorgespannt verbaut ist, dass im gesamten Bereich der im normalen Betrieb auftretenden Zug- und Druckkräfte eine spielfreie Anlage gewährleistet ist. Das Innengehäuse und das Außengehäuse können dann so ausgebildet sein, dass Zugkräfte zwischen ihnen formschlüssig übertragen werden können.The invention uses a design of an energy-absorbing connection device in which the energy absorber, which itself can only transmit compressive forces, is installed prestressed between the inner housing and the outer housing in such a way that a play-free system is guaranteed over the entire range of the tensile and compressive forces occurring during normal operation. The inner housing and the outer housing can then be designed in such a way that tensile forces can be transmitted between them in a form-fitting manner.

Die Verbindungseinrichtung kann auch zusätzlich elastische Federungen umfassen, die Druckkräfte unterhalb der vorbestimmten Druckkraft abfedern können. Erst wenn diese Federungen voll komprimiert sind und starr werden, kommt es zu einer irreversiblen Verformung im Energieabsorber.The connecting device can also additionally comprise elastic springs, which can cushion compressive forces below the predetermined compressive force. Only when these springs are fully compressed and become rigid does an irreversible deformation occur in the energy absorber.

Vorzugsweise umfasst der Energieabsorber eine Energieabsorptionshülse und eine Druckstange, wobei die Druckstange und die Energieabsorptionshülse so eingerichtet sind, dass sich die Druckstange beim Überschreiten der vorbestimmten Druckkraft in die Energieabsorptionshülse einschiebt und diese irreversibel verformt. Die Druckstange und die Energieabsorptionshülse können sich entlang der Längsachse erstecken und im Ruhezustand der Verbindungseinrichtung an einander zugewandten Stirnseiten formschlüssig anliegen. Die Energieabsorptionshülse kann in Längsrichtung einen Verformungsabschnitt und einen Rückabschnitt umfassen, wobei vorzugsweise lediglich der Verformungsabschnitt durch die Druckstange zur kontrollierten, irreversiblen Verformung eingerichtet ist.The energy absorber preferably comprises an energy absorption sleeve and a pressure rod, the pressure rod and the energy absorption sleeve being set up in such a way that the pressure rod pushes into the energy absorption sleeve when the predetermined pressure force is exceeded and deforms it irreversibly. The push rod and the energy absorbing sleeve can extend along the longitudinal axis and, when the connecting device is in the idle state, can rest in a form-fitting manner on end faces facing one another. The energy absorption sleeve can comprise a deformation section and a rear section in the longitudinal direction, wherein preferably only the deformation section is set up for controlled, irreversible deformation by the push rod.

Es ist bevorzugt, wenn an einem axialen Ende der Druckstange ein Druckring angeordnet ist, der beim Einschieben der Druckstange in die Energieabsorptionshülse die Energieabsorptionshülse radial entlang der Längsachse aufweitet. Die Druckkraft kann dann vom Innengehäuse über die Druckstange auf den Druckring aufgebracht werden. Damit wird eine konstante Bremskraft und Energieabsorption bereitgestellt. Der Druckring kann eine größere radiale Dicke als die Energieabsorptionshülle aufweisen. Die Energieabsorptionshülle kann dazu in einem Verformungsabschnitt einen geringeren Außenradius aufweisen als in einem Rückabschnitt. Die Verbindungseinrichtung kann in Längsrichtung auf Höhe des Verformungsabschnitts einen, vorzugsweise zylinderringförmigen, Hohlraum aufweisen, in dem der Verformungsabschnitt aufgeweitet werden kann. Es sind unter Beibehaltung des Prinzips der Verspannung auch andere geometrische Anordnungen oder andere Wirkprinzipien des Energieabsorbers (z. B. Falten oder Zerspanen während der irreversiblen Verformung) denkbar.It is preferred if a pressure ring is arranged on one axial end of the pressure rod, which widens the energy absorption sleeve radially along the longitudinal axis when the pressure rod is pushed into the energy absorption sleeve. The pressure force can then be applied to the pressure ring from the inner housing via the pressure rod. This provides constant braking power and energy absorption. The compression ring may have a greater radial thickness than the energy absorbing shroud. For this purpose, the energy absorption cover can have a smaller outer radius in a deformation section than in a rear section. The connecting device can have a hollow space, preferably in the form of a cylindrical ring, in the longitudinal direction at the level of the deformation section, in which cavity the deformation section can be widened. Other geometric arrangements or other active principles of the energy absorber (eg folding or chipping during the irreversible deformation) are also conceivable while retaining the principle of bracing.

Vorzugsweise weist der Druckring einen konisch in Längsrichtung zulaufenden Querschnitt auf; somit kann der Druckring in kontrollierter und gleichmäßiger Weise die Energieabsorptionshülle aufweiten. Die Gefahr eines Verkantens der Druckstange und der Energieabsorptionshülse und somit eines Versagens des Energieabsorbers wird reduziert.Preferably, the pressure ring has a cross-section tapering in the longitudinal direction; thus, the compression ring can expand the energy absorption envelope in a controlled and uniform manner. The risk of the push rod and the energy absorption sleeve tilting and thus of the energy absorber failing is reduced.

Vorzugsweise sind jeweils ein axiales Ende des Energieabsorbers und des Außengehäuses mit einem gemeinsamen Deckel verbunden. Zur Herstellung einer Verspannung können die auf die Verbindungseinrichtung wirkenden Zugkräfte über einen mit dem Außengehäuse verbundenen (z. B. verschraubten) Deckel in Druckkräfte auf den Energieabsorber umgelenkt werden. Der Deckel kann mit mehreren Schrauben an der Energieabsorptionshülse und dem Außengehäuse befestigt sein. Alternativ zu einem Deckel sind auch Ausführungsformen mit einer zentralen einzelnen Schraube oder Mutter zur Verbindung mit der Energieabsorptionshülse und dem Außengehäuse möglich.An axial end of the energy absorber and of the outer housing are preferably each connected to a common cover. In order to produce a bracing, the tensile forces acting on the connecting device can be deflected into compressive forces on the energy absorber via a cover connected (e.g. screwed) to the outer housing. The lid may be attached to the energy absorbing sleeve and the outer case with multiple screws. As an alternative to a cover, there are also embodiments with a central single bolt or nut for connection to the energy absorbing sleeve and the outer housing.

Es ist bevorzugt, wenn die Mitnahmeeinrichtung zumindest teilweise in einem Lastpfad der Zugkraftübertragung der Verbindungseinrichtung angeordnet ist. Im normalen Betrieb (unter Einwirkung einer Zugkraft) ist die Anbindung der Gehäuseteile über die Mitnahmeeinrichtung dann genauso belastbar wie eine durchgehende Verbindung zwischen den Gehäuseteilen, da sie voll im Kraftfluss liegt.It is preferred if the entraining device is at least partially arranged in a load path of the tensile force transmission of the connecting device. In normal operation (under the effect of a tensile force), the connection of the housing parts via the entrainment device can then be loaded just as strongly as a continuous connection between the housing parts, since it lies fully in the power flow.

In einer bevorzugten Ausführungsform umfasst die Verbindungseinrichtung Funktionsflächen zur formschlüssigen Übertragung von Zugkräften zwischen dem Außengehäuse und dem Innengehäuse, wobei die Funktionsflächen als halbe Rotationszylinder im Außengehäuse und im Innengehäuse ausgebildet sind.In a preferred embodiment, the connecting device comprises functional surfaces for the positive transmission of tensile forces between the outer housing and the inner housing, the functional surfaces being designed as half rotary cylinders in the outer housing and in the inner housing.

Es ist vorgesehen, dass die Verbindungseinrichtung Funktionsflächen zur formschlüssigen Übertragung von Zugkräften zwischen dem Außengehäuse und dem Innengehäuse umfasst, wobei die Funktionsflächen als Langlöcher im Außengehäuse und im Innengehäuse ausgebildet sind, und wobei die Mitnahmeeinrichtung in beiden Langlöchern in Querrichtung geführt ist. Die Funktionsflächen können in dem Außengehäuse und dem Innengehäuse als Langlöcher angeordnet sein, die wenigstens so lang bemessen sind, dass sich die Mitnahmeeinrichtung bei einer irreversiblen Verformung um den halben nominellen Hub des Energieabsorbers in Längsrichtung darin bewegen kann. Die Funktionsflächen sind vorzugsweise an den Enden der Langlöcher angeordnet. Die Funktionsflächen verspannen so die Mitnahmeeinrichtung in Ausgangslage zwischen den Gehäuseteilen bzw. begrenzen diese im deformierten Zustand in ihrer Längsbewegung.It is provided that the connecting device comprises functional surfaces for the positive transmission of tensile forces between the outer housing and the inner housing, with the functional surfaces being designed as slots in the outer housing and in the inner housing, and with the driver device being guided in both slots in the transverse direction. The functional surfaces can be arranged in the outer housing and the inner housing as oblong holes that are dimensioned at least long enough for the driver device to move in the longitudinal direction in the longitudinal direction by half the nominal stroke of the energy absorber in the event of irreversible deformation. The functional surfaces are preferably arranged at the ends of the elongated holes. In this way, the functional surfaces clamp the driver device in the initial position between the housing parts or limit its longitudinal movement in the deformed state.

Die erfindungsgemäße Aufgabe wird auch durch einen Wagenkasten umfassend ein Wagenkastengehäuse und mindestens eine mit dem Wagenkastengehäuse verbundene Verbindungseinrichtung nach einer der vorstehenden Ausführungsformen gelöst. Der Wagenkasten kann hier und im Rahmen dieser Anmeldung ein kurzer Wagenkasten oder auch nur ein Wagenkastensegment sein.The object according to the invention is also achieved by a car body comprising a car body housing and at least one connected to the car body housing Connection device solved according to one of the preceding embodiments. Here and in the context of this application, the car body can be a short car body or just a car body segment.

Vorzugsweise ist die Verbindungseinrichtung über die Mitnahmeeinrichtung mit dem Wagenkastengehäuse verbunden. Die Befestigung des Wagenkastengehäuses an der Mitnahmeeinrichtung kann formschlüssig über einen Mitnahmezapfen erfolgen.The connecting device is preferably connected to the car body housing via the entrainment device. The car body housing can be fastened to the entrainment device in a form-fitting manner using an entrainment pin.

Mit der vorliegenden Erfindung wird die starre Zuordnung des an der Mitnahmeeinrichtung befestigten Wagenkastens zu einem der beiden durch den Energieabsorber verbundenen Wagenkästen aufgehoben. Im Falle der irreversiblen Verformung bei einer Kollision kann sich der Wagenkasten zwischen den angrenzenden Wagenkästen unabhängig von der Verformungskraft des Energieabsorbers bewegen, womit alle Freiräume in Längsrichtung für einen energieabsorbierenden Hub zur Verfügung stehen. Im normalen Betrieb dagegen ist die Anbindung an der Mitnahmeeinrichtung, da voll im Kraftfluss liegend, genauso belastbar wie eine bekannte durchgehende Verbindungseinrichtung.With the present invention, the rigid assignment of the car body attached to the entrainment device to one of the two car bodies connected by the energy absorber is eliminated. In the event of irreversible deformation in a collision, the car body can move between the adjacent car bodies independently of the deformation force of the energy absorber, which means that all the free spaces in the longitudinal direction are available for an energy-absorbing stroke. In normal operation, on the other hand, the connection to the driving device is just as resilient as a known continuous connection device, since it lies fully in the power flow.

Die Erfindung erlaubt die Anordnung der Mitnahmeeinrichtung zur Anbindung im Kraftfluss der Verspannung des Energieabsorbers. Die Erfindung erlaubt die zuverlässige Realisierung vergleichsweise kurzer und leichter Wagenkästen(-segmente) eines mehrgliedrigen Schienenfahrzeugs bei optimaler Nutzung der funktional bedingten Bewegungsfreiräume für einen energieabsorbierenden Hub bei einer Kollision.The invention allows the driver device to be arranged for connection in the force flow of the bracing of the energy absorber. The invention allows the reliable realization of comparatively short and light car bodies (segments) of a multi-part rail vehicle with optimal use of the functionally conditioned freedom of movement for an energy-absorbing stroke in the event of a collision.

Die Figuren 1 bis 4 zeigen dieselbe Ausführungsform einer erfindungsgemäßen Verbindungseinrichtung 1. Figuren 1 und 2 zeigen die Verbindungseinrichtung 1 in gestreckter Position unter Zug, also im normalen Betrieb eines Schienenfahrzeugs. Figuren 3 und 4 zeigen die Verbindungseinrichtung 1 nach der irreversiblen Verformung des Energieabsorbers, also beispielsweise nach einer Kollision.The Figures 1 to 4 show the same embodiment of a connecting device 1 according to the invention. Figures 1 and 2 show the connecting device 1 in the extended position under train, ie during normal operation of a rail vehicle. Figures 3 and 4 show the connecting device 1 after the irreversible deformation of the energy absorber, for example after a collision.

Die Verbindungseinrichtung 1 umfasst ein Außengehäuse 2, ein Innengehäuse 3 und einen mit dem Außengehäuse 2 und dem Innengehäuse 3 verbundenen Energieabsorber 4. Das Außengehäuse 2, das Innengehäuse 3 und der Energieabsorber 4 sind im Wesentlichen entlang einer gemeinsamen Längsachse angeordnet (hier die Vertikale).The connecting device 1 comprises an outer housing 2, an inner housing 3 and an energy absorber 4 connected to the outer housing 2 and the inner housing 3. The outer housing 2, the inner housing 3 and the energy absorber 4 are arranged essentially along a common longitudinal axis (here the vertical).

Die Verbindungseinrichtung 1 ist dazu eingerichtet, Zugkräfte und Druckkräfte entlang der Längsachse zu übertragen. Der Energieabsorber 4 ist dazu eingerichtet, sich bei einem Überschreiten einer vorbestimmten Druckkraft entlang der Längsachse irreversibel zu verformen, sodass sich die Länge der Verbindungseinrichtung 1 entlang der Längsachse reduziert und sich das Innengehäuse 3 teilweise in das Außengehäuse 2 schiebt. Das Resultat dieser irreversiblen Verformung ist in den Figuren 3 und 4 dargestellt.The connecting device 1 is set up to transmit tensile forces and compressive forces along the longitudinal axis. The energy absorber 4 is designed to when a predetermined compressive force is exceeded along the To deform the longitudinal axis irreversibly, so that the length of the connecting device 1 is reduced along the longitudinal axis and the inner housing 3 is partially pushed into the outer housing 2 . The result of this irreversible deformation is Figures 3 and 4 shown.

Die Verbindungseinrichtung 1 kann auch zusätzlich elastische Federungen 5 umfassen, die Druckkräfte unterhalb der vorbestimmten Druckkraft abfedern können. Erst wenn diese Federungen 5 voll komprimiert sind und hart werden, kommt es zu einer irreversiblen Verformung im Energieabsorber 4. Die Federungen 5 sind hier als jeweils zwei elastische Federringe ausgebildet.The connecting device 1 can also additionally comprise elastic springs 5, which can cushion compressive forces below the predetermined compressive force. Only when these springs 5 are fully compressed and become hard does irreversible deformation occur in the energy absorber 4. The springs 5 are each designed here as two elastic spring rings.

In der dargestellten Ausführungsform umfasst der Energieabsorber 4 eine Energieabsorptionshülse 6 und eine Druckstange 7. Die Druckstange 7 und die Energieabsorptionshülse 6 sind so eingerichtet, dass sich die Druckstange 7 beim Überschreiten der vorbestimmten Druckkraft in die Energieabsorptionshülse 6 einschiebt und diese irreversibel verformt. Die Druckstange 7 und die Energieabsorptionshülse 6 können sich entlang der Längsachse erstecken und im Ruhezustand der Verbindungseinrichtung 1 an einander zugewandten Stirnseiten formschlüssig anliegen (siehe Figur 2). In der dargestellten Ausführungsform umfasst die Energieabsorptionshülse 6 eine radiale Aufweitung in der die Druckstange 7 anliegt.In the embodiment shown, the energy absorber 4 comprises an energy absorption sleeve 6 and a push rod 7. The push rod 7 and the energy absorption sleeve 6 are set up in such a way that the push rod 7 pushes into the energy absorption sleeve 6 when the predetermined compressive force is exceeded and deforms it irreversibly. The push rod 7 and the energy absorption sleeve 6 can extend along the longitudinal axis and, when the connecting device 1 is in the idle state, can rest in a form-fitting manner on facing end faces (see FIG figure 2 ). In the illustrated embodiment, the energy absorption sleeve 6 includes a radial expansion in which the push rod 7 rests.

Die Energieabsorptionshülse 6 umfasst in Längsrichtung einen Verformungsabschnitt 8 und einen Rückabschnitt 9, wobei vorzugsweise lediglich der Verformungsabschnitt 8 durch die Druckstange 7 zur kontrollierten, irreversiblen Verformung eingerichtet ist.The energy absorption sleeve 6 comprises a deformation section 8 and a rear section 9 in the longitudinal direction, with preferably only the deformation section 8 being set up by the push rod 7 for controlled, irreversible deformation.

An einem axialen Ende der Druckstange 7 ist ein Druckring 10 angeordnet, der beim Einschieben der Druckstange 7 in die Energieabsorptionshülse 6 die Energieabsorptionshülse 6 radial entlang der Längsachse aufweitet (vergleiche Figuren 2 und 4). Der Druckring kann einstückig mit der Druckstange 7 ausgebildet sein oder formschlüssig oder stoffschlüssig mit der Druckstange 7 verbunden sein. Die Druckkraft kann dann vom Innengehäuse 3 über die Druckstange 7 auf den Druckring 10 aufgebracht werden. Damit wird eine konstante Bremskraft und Energieabsorption bereitgestellt.At one axial end of the push rod 7 there is a pressure ring 10 which, when the push rod 7 is pushed into the energy absorption sleeve 6, expands the energy absorption sleeve 6 radially along the longitudinal axis (cf figures 2 and 4 ). The pressure ring can be designed in one piece with the push rod 7 or can be connected to the push rod 7 in a form-fitting or material-locking manner. The pressure force can then be applied to the pressure ring 10 by the inner housing 3 via the pressure rod 7 . This provides constant braking power and energy absorption.

Der Druckring 10 kann eine größere radiale Dicke als die Energieabsorptionshülle 6 aufweisen. Die Energieabsorptionshülle 6 kann dazu in dem Verformungsabschnitt 8 einen geringeren Außenradius aufweisen als in dem Rückabschnitt 9. Die Verbindungseinrichtung 1 kann in Längsrichtung auf Höhe des Verformungsabschnitts 8 einen, vorzugsweise zylinderringförmigen, Hohlraum 11 aufweisen, in dem der Verformungsabschnitt 8 aufgeweitet werden kann. Der Hohlraum 11 kann in Radialrichtung zwischen der Energieabsorptionshülle 6 und dem Außengehäuse 2 angeordnet sein.The pressure ring 10 can have a greater radial thickness than the energy absorption sleeve 6 . For this purpose, the energy absorption cover 6 can have a smaller outer radius in the deformation section 8 than in the rear section 9. The connecting device 1 can have a preferably cylindrical cavity 11 in the longitudinal direction at the height of the deformation section 8, in which the deformation section 8 can be widened. The hollow space 11 can be arranged between the energy absorption cover 6 and the outer housing 2 in the radial direction.

Der Druckring 10 weist einen konisch in Längsrichtung zulaufenden Querschnitt auf; somit kann der Druckring 10 in kontrollierter und gleichmäßiger Weise die Energieabsorptionshülle 6 aufweiten. Die Gefahr eines Verkantens der Druckstange 7 und der Energieabsorptionshülse 6 und somit eines Versagens des Energieabsorbers 4 wird reduziert.The pressure ring 10 has a conically tapering cross-section in the longitudinal direction; thus, the pressure ring 10 can expand the energy absorption envelope 6 in a controlled and uniform manner. The risk of the push rod 7 and the energy absorption sleeve 6 tilting and thus of the energy absorber 4 failing is reduced.

Axiale Enden des Energieabsorbers 4 und des Außengehäuses 2 sind mit einem gemeinsamen Deckel 12 verbunden. Der Deckel 12 kann mit mehreren Schrauben an der Energieabsorptionshülse 6 und dem Außengehäuse 2 befestigt sein.Axial ends of the energy absorber 4 and the outer housing 2 are connected to a common cover 12 . The cover 12 can be fastened to the energy absorption sleeve 6 and the outer housing 2 with several screws.

Die Verbindungseinrichtung 1 umfasst eine Mitnahmeeinrichtung 13 zur Verbindung der Verbindungseinrichtung 1 mit einem Wagenkastengehäuse eines Wagenkastens. Die Mitnahmeeinrichtung 13 ist als eine formschlüssige Verbindung zur Übertragung von Zugkräften zwischen dem Innengehäuse 3 und dem Außengehäuse 2 vorgesehen. Die Mitnahmeeinrichtung 13 ist mit dem Innengehäuse 3 und dem Außengehäuse 2 zugfest verbunden, jedoch nicht druckfest verbunden. Die Mitnahmeeinrichtung 13 ist hier als rotationssymmetrische Hülse ausgebildet, die vorzugsweise in Querrichtung senkrecht zur Längsrichtung verläuft. Die Befestigung der Verbindungseinrichtung 1 an einem Wagenkasten mittels der Mitnahmeeinrichtung 13 kann formschlüssig über einen Mitnahmezapfen 15 erfolgen.The connecting device 1 comprises a driving device 13 for connecting the connecting device 1 to a car body housing of a car body. The driver device 13 is provided as a form-fitting connection for the transmission of tensile forces between the inner housing 3 and the outer housing 2 . The take-along device 13 is firmly connected to the inner housing 3 and the outer housing 2, but not pressure-tight. The driver device 13 is designed here as a rotationally symmetrical sleeve, which preferably runs in the transverse direction perpendicular to the longitudinal direction. The connection device 1 can be fastened to a car body by means of the driving device 13 in a form-fitting manner via a driving pin 15 .

Die Verbindungseinrichtung 1 umfasst Funktionsflächen zur formschlüssigen Übertragung von Zugkräften zwischen dem Außengehäuse 2 und dem Innengehäuse 3, wobei die Funktionsflächen als Langlöcher 14 im Außengehäuse 2 und im Innengehäuse 3 ausgebildet sind. Die Mitnahmeeinrichtung 13 ist in beiden Langlöchern 14 in Querrichtung geführt.The connecting device 1 comprises functional surfaces for the positive transmission of tensile forces between the outer housing 2 and the inner housing 3, the functional surfaces being designed as oblong holes 14 in the outer housing 2 and in the inner housing 3. The entraining device 13 is guided in the two elongated holes 14 in the transverse direction.
