Definitions
- the invention relates to a coupling device for a rail vehicle according to the preamble of claim 1.
- Coupling devices of this type are known to be used for coupling rail vehicles on passenger or freight trains, such as one in the publication EP-A-2 322 403 is explained. They basically consist of two coupling halves, which are arranged on each rail vehicle and can be coupled to one another. They are each provided with a coupling head and a towing device for transmitting the tensile and impact forces to the vehicle body WO 2005/075272 A1 known.
- a safety device provided in at least one coupling absorbs the impact energy by converting it into deformation energy within certain limits. This deformation energy is generated in such a way that a support of the coupling interacting with the pipe section has a larger diameter than the inner diameter of the pipe section and thereby expands it and deforms it accordingly when it is pressed into the pipe section in the event of an impact.
- the object of the invention is to avoid these disadvantages and to create a coupling device of the type mentioned at the outset, the passive safety device of which is effective as evenly as possible over a long deformation path in the event of an impact.
- the passive safety device of which is effective as evenly as possible over a long deformation path in the event of an impact.
- the safety element of the coupling can work without cracks and jolts because no jamming and/or violent vibrations occur during the impact, which counteract the uniform advance of the support in the pipe section along the deformation path of the pipe section.
- the invention provides that the piece of pipe is preferably primed with a base color and the support with a sliding ring is made of sliding material, preferably nodular cast iron (grey cast iron). In this way it is possible to produce the support body carrying the slide ring from the material most suitable for its function.
- nodular cast iron grey cast iron
- the piece of pipe is expediently made from a one-piece pipe which continuously has the inner diameter provided in its deformation area.
- the invention also provides that the pipe end provided with the pipe enlargement protrudes into an annular gap between the coupling flange and the support and can be fastened there to the coupling flange on the inside or outside with a detachable connection, preferably a screw or bayonet connection. This enables the pipe section to be installed and removed directly from the fully assembled coupling half or one that is installed in the vehicle.
- the other end of the pipe section facing away from the coupling flange is open. Since the proposed passive safety element can naturally only absorb a certain amount of energy, the open tube end allows the support interacting with the tube section to be pushed beyond the open tube end into the interior of the vehicle body in the event of a frontal collision, depending on the mass and speed of the impacting wagon or wagons becomes.
- the coupling flange is provided with connecting means for holding the support, preferably in the form of shear bolts, which are released automatically at a defined impact force in order to release the support. This ensures that the support in the pipe extension receiving it remains intact in the event of slight backward or impact movements of the coupling and only becomes effective in an emergency when the defined impact force is reached, by penetrating the pipe section in order to deform it in an energy-absorbing manner.
- the support In normal operation, when the shear bolt is connected, the support is expediently in contact with the piece of pipe, so that no operating forces are conducted via this shear bolt. In this way, on the one hand, the breakaway force can be adjusted independently of the shearing force of this connection means and, on the other hand, a setting between the support and the pipe section or a change in the release force over time is prevented.
- FIG. 1 shows a coupling 1 for a rail vehicle whose coupling head (not shown) can be articulated on a bolt 2 of a coupling part 3 .
- This coupling part 3 has a cylindrical projection 4 with a support 5 on the front side, which is guided in a coupling flange 6 designed in the shape of a star or the like and is fixed there by shear bolts 7 as connecting means.
- the coupling flange 6 is in turn screwed tightly, for example, in the vehicle body of the rail vehicle, which is not shown in detail.
- a piece of pipe 8 Arranged as an extension of the extension 4 is a piece of pipe 8 which, in the event of an impact, acts as a passive safety element with the support 5 by penetrating the piece of pipe and expanding it, with the piece of pipe absorbing the energy of the impact within certain limits as it deforms. In the normal operation shown, the support 5 rests against the expanded piece of pipe 8 . However, a distance could also be provided between them, so that the axial forces occurring during normal operation would not be transmitted to them, but via the shear bolt 7.
- the pipe end 9 of the pipe section 8 protrudes into an annular intermediate space 10 between the support 5 and the coupling flange 6 and is detachably fastened to it there.
- a releasable screw connection 11 is provided, which allows the installation and removal of the pipe section 8 in the completely assembled coupling, even after it has been installed in the vehicle body of the vehicle. This also makes it possible to subsequently install the pipe section 8 in vehicles that originally had no passive safety elements.
- the screw connection 11 it can also be a bayonet or the like.
- the piece of pipe 8 has an inside diameter that is the same or varies throughout its deformation area and is provided on the inside of the pipe end 9 with a diameter enlargement 12 that accommodates the support 5 .
- this increase in diameter in the piece of pipe or in the case of the support is formed on the outside by a corresponding conical expansion.
- the piece of pipe 8 is well positioned and centered on the support 5.
- the pipe section 8 only has to be machined on the inside in the area of the diameter expansion. This greatly facilitates the processing of the piece of pipe, especially since its pipe length can be one meter or more in practice.
- a separate flange 14' is attached to the pipe piece 8 at the other pipe end 14, which is dimensioned with its inner and/or outer diameter such that the force acting against the impact force via the support 5 is opposite to this flange 14' the piece of pipe 8 is variable.
- this flange 14' is reduced in terms of its inside diameter or increased in terms of its outside diameter compared to the piece of pipe 8. The force counteracting the impact force is thus increased in this flange 14'.
- This dimensioning can be varied depending on the application and more than one such flange 14' could also be provided.
- the purpose of fixing the extension 4 in the coupling flange 6 with the shear bolts 7 is to prevent the support 5 from becoming unstable in the area of the diameter expansion 12 as a result of vibrations or slight recoils during normal operation.
- the shear bolts 7 are sheared off when a certain impact force is reached, and the support 5 is released so that it can penetrate unhindered into the deformation area of the pipe piece 8 and widen it.
- the invention provides for the pipe section 8 to be expanded by the support 5 in the area of a plastic deformation, with the materials of the pipe and the slide ring 13 being matched to one another in this way are that in the event of an impact, the support 5 slides along against the inside of the pipe section 8 with an approximately uniform frictional force.
- the pipe section 8 is expediently coated on the inside, advantageously primed with a base color, while the support 5 is provided with the slide ring 13 made of a sliding material, preferably nodular cast iron (grey cast iron).
- This choice of material ensures that, in the event of an impact, the deformation of the pipe section 8 takes place largely without jerks within certain impact forces and without an increase in force or force peaks over the entire deformation range of the pipe.
- the pipe section 8 is open at its pipe end 14 remote from the coupling flange 6 and opens there into a likewise open interior of the vehicle body, not shown, into which the support 5 is pushed in the event of a frontal collision, depending on the mass and/or speed of the impacting vehicle.
- the passive safety device described can be installed either in just one or in both halves of the clutch.
- the piece of pipe could be provided with an enlarged diameter as an annular recess.
- the piece of pipe with the pipe end 14 could also be made from a one-piece pipe.

Description
Die Erfindung betrifft eine Kupplungseinrichtung für ein Schienenfahrzeug nach dem Oberbegriff des Anspruchs 1.The invention relates to a coupling device for a rail vehicle according to the preamble of
Kupplungseinrichtungen dieser Art werden bekanntlich für das Kuppeln von Schienenfahrzeugen bei Personen- oder Güterzügen eingesetzt, wie eine solche in der Druckschrift
Bei einem möglichen Aufprall zwischen zwei Schienenfahrzeugen bei den Kupplungen oder einer Kupplung eines Fahrzeugs mit einem Prellbock am Gleisende ist vorgesehen, dass ein in mindestens einer Kupplung vorgesehenen Sicherheitseinrichtung die Aufprallenergie durch Umwandeln derselben in Verformungsenergie innerhalb bestimmter Grenzen absorbiert. Diese Verformungsenergie wird in der Weise generiert, dass ein mit dem Rohrstück zusammenwirkende Support der Kupplung einen grösseren Durchmesser als der Innendurchmesser des Rohrstücks aufweist und dadurch dieses aufweitet und dementsprechend verformt, wenn sie bei einem Aufprall in das Rohrstück gedrückt wird.In the event of a possible collision between two rail vehicles at the couplings or a coupling of a vehicle with a buffer stop at the end of the track, it is provided that a safety device provided in at least one coupling absorbs the impact energy by converting it into deformation energy within certain limits. This deformation energy is generated in such a way that a support of the coupling interacting with the pipe section has a larger diameter than the inner diameter of the pipe section and thereby expands it and deforms it accordingly when it is pressed into the pipe section in the event of an impact.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Kupplungseinrichtung der eingangs genannten Art zu schaffen, deren passive Sicherheitseinrichtung bei einem Aufprall möglichst gleichmässig über eine lange Verformungsstrecke wirksam ist. Dazu soll ermöglicht werden, das Rohrstück nachträglich in Fahrzeuge einzubauen, die ursprünglich über keine passiven Sicherheitselemente verfügt hatten.The object of the invention is to avoid these disadvantages and to create a coupling device of the type mentioned at the outset, the passive safety device of which is effective as evenly as possible over a long deformation path in the event of an impact. In addition, it should be possible to subsequently install the piece of pipe in vehicles that originally had no passive safety elements.
Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by the features of
Das Sicherheitselement der Kupplung kann riss- und ruckfrei arbeiten, weil während des Aufpralls keine Verklemmungen und/oder heftigen Schwingungen entstehen, die dem gleichmässigen Vordringen des Supports im Rohrstück entlang der Verformungsstrecke des Rohrstücks entgegenwirken.The safety element of the coupling can work without cracks and jolts because no jamming and/or violent vibrations occur during the impact, which counteract the uniform advance of the support in the pipe section along the deformation path of the pipe section.
Die Erfindung sieht in diesem Sinne vor, dass das Rohrstück vorzugsweise mit einer Grundfarbe grundiert ist und der Support mit einem Gleitring aus gleitendem Material, vorzugsweise Sphäroguss (Grauguss), hergestellt ist. Auf diese Weise ist es möglich, den Gleitring tragenden Supportkörper aus dem für seine Funktion am besten geeigneten Werkstoff herzustellen.In this sense, the invention provides that the piece of pipe is preferably primed with a base color and the support with a sliding ring is made of sliding material, preferably nodular cast iron (grey cast iron). In this way it is possible to produce the support body carrying the slide ring from the material most suitable for its function.
Zweckmässigerweise ist das Rohrstück aus einem einstückigen Rohr hergestellt, das durchgehend den in seinem Verformungsbereich vorgesehenen Innendurchmesser aufweist.The piece of pipe is expediently made from a one-piece pipe which continuously has the inner diameter provided in its deformation area.
Es ist dabei zum Positionieren und Zentrieren des Rohrstücks auf dem Support vorteilhaft, wenn das Rohrstück an dem einen Rohrende innenseitig mit einer den Support aufnehmenden Durchmessererweiterung versehen ist. Das hat ausserdem den Vorteil, dass das Rohrstück innenseitig nur bei der den Support aufnehmen Aufweitung bearbeitet werden muss, was sonst schwierig ist, da das Rohrstück mit einer Länge von bis zu einem Meter oder noch länger dimensioniert werden kann.It is advantageous for positioning and centering the piece of pipe on the support if the piece of pipe is provided on the inside at one end of the pipe with a diameter enlargement that accommodates the support. This also has the advantage that the pipe section only has to be machined on the inside when the support is widened, which is otherwise difficult since the pipe section can be dimensioned with a length of up to one meter or even longer.
Die Erfindung sieht weiterhin vor, dass das mit der Rohrerweiterung versehene Rohrende in einen ringförmigen Spalt zwischen dem Kupplungsflansch und dem Support hineinragt und dort an den Kupplungsflansch innen- oder aussenseitig mit einer lösbaren Verbindung wie vorzugsweise eine Schraub- oder Bajonettverbindung befestigbar ist. Das ermöglicht den direkten Ein- und Ausbau des Rohrstücks an die fertig zusammengebaute oder im Fahrzeug eingebaute Kupplungshälfte.The invention also provides that the pipe end provided with the pipe enlargement protrudes into an annular gap between the coupling flange and the support and can be fastened there to the coupling flange on the inside or outside with a detachable connection, preferably a screw or bayonet connection. This enables the pipe section to be installed and removed directly from the fully assembled coupling half or one that is installed in the vehicle.
Das andere, vom Kupplungsflansch abgekehrte Rohrende des Rohrstücks ist offen. Da das vorgeschlagene passive Sicherheitselement naturgemäss nur eine bestimmte Energie aufnehmen kann, ermöglicht das offene Rohrende, dass bei einer Frontalkollision den mit dem Rohrstück zusammenwirkende Support je nach Masse und Geschwindigkeit des oder der aufprallenden Waggons über das offene Rohrende hinaus bis in den Innenraum des Fahrzeugkastens gestossen wird.The other end of the pipe section facing away from the coupling flange is open. Since the proposed passive safety element can naturally only absorb a certain amount of energy, the open tube end allows the support interacting with the tube section to be pushed beyond the open tube end into the interior of the vehicle body in the event of a frontal collision, depending on the mass and speed of the impacting wagon or wagons becomes.
Der Kupplungsflansch ist mit vorzugsweise als Abscherbolzen ausgebildeten Verbindungsmitteln zum Halten des Supports versehen, die sich bei einer definierten Aufprallkraft selbsttätig lösen, um den Support freizugeben. Damit wird sichergestellt, dass bei leichten Rück- oder Stossbewegungen der Kupplung der Support in der ihn aufnehmenden Rohrerweiterung unversehrt bleibt und nur im Notfall bei Erreichen der jeweils definierten Aufprallkraft wirksam wird, indem er dann in das Rohrstück eindringt, um dieses energieabsorbierend zu verformen.The coupling flange is provided with connecting means for holding the support, preferably in the form of shear bolts, which are released automatically at a defined impact force in order to release the support. This ensures that the support in the pipe extension receiving it remains intact in the event of slight backward or impact movements of the coupling and only becomes effective in an emergency when the defined impact force is reached, by penetrating the pipe section in order to deform it in an energy-absorbing manner.
Zweckmässigerweise liegt im Normalbetrieb bei verbundenem Abscherbolzen der Support an dem Rohrstück an, so dass keine Betriebskräfte über diesen Abscherbolzen geleitet werden. Damit kann einerseits die Losbrechkraft unabhängig von der Abscherkraft dieses Verbindungsmittels eingestellt werden und anderseits wird ein Setzen zwischen dem Support und dem Rohrstück oder eine Veränderung der Auslösekraft über die Zeit verhindert.In normal operation, when the shear bolt is connected, the support is expediently in contact with the piece of pipe, so that no operating forces are conducted via this shear bolt. In this way, on the one hand, the breakaway force can be adjusted independently of the shearing force of this connection means and, on the other hand, a setting between the support and the pipe section or a change in the release force over time is prevented.

In Verlängerung des Ansatzes 4 ist ein Rohrstück 8 angeordnet, das bei einem Aufprall als passives Sicherheitselement mit dem Support 5 zusammenwirkt, indem diese in das Rohrstück eindringt und ihn aufweitet, wobei das Rohrstück bei seiner Verformung die Energie des Aufpralls innerhalb bestimmter Grenzen absorbiert. Im gezeigten Normalbetrieb liegt der Support 5 an dem erweiterten Rohrstück 8 an. Es könnte jedoch auch eine Distanz zwischen diesen vorgesehen sein, so dass die im Normalbetrieb entstehenden Axialkräfte nicht bei diesen übertragen würde, sondern über den Abscherbolzen 7.Arranged as an extension of the extension 4 is a piece of
Erfindungsgemäss ragt das Rohrende 9 des Rohrstücks 8 in einen ringförmigen Zwischenraum 10 zwischen dem Support 5 und dem Kupplungsflansch 6 und ist dort an diesem lösbar befestigt. Eine lösbare Schraubverbindung 11 ist vorgesehen, die den Ein- und Ausbau des Rohrstücks 8 in der fertig zusammengebauten Kupplung ermöglicht, auch nach deren Einbau in den Fahrzeugkasten des Fahrzeugs. Dadurch ist es auch möglich, das Rohrstück 8 nachträglich in Fahrzeuge einzubauen, die ursprünglich über keine passiven Sicherheitselemente verfügt hatten. Anstelle der Schraubverbindung 11 kann es sich auch um ein Bajonett oder ähnliches handeln.According to the invention, the
Das Rohrstück 8 weist einen durchgehend in seinem Verformungsbereich vorgesehenen gleichen oder verändernden Innendurchmesser auf und ist am Rohrende 9 innenseitig mit einer den Support 5 aufnehmenden Durchmessererweiterung 12 versehen. Vorteilhaft sind diese Durchmessererweiterung im Rohrstück bzw. bei dem Support aussen durch eine korrespondierende kegelförmige Erweiterung gebildet. Dadurch ist das Rohrstück 8 auf dem Support 5 gut positioniert und zentriert. Es ist ausserdem von Vorteil, dass das Rohrstück 8 innenseitig nur im Bereich der Durchmessererweiterung bearbeitet werden muss. Dadurch wird die Bearbeitung des Rohrstücks sehr erleichtert, zumal seine Rohrlänge in der Praxis ein Meter und mehr betragen kann.The piece of
Im Rahmen der Erfindung ist bei dem Rohrstück 8 an dem anderen Rohrende 14 ein separater Flansch 14' befestigt, welcher mit seinem Innen- und/oder Aussendurchmesser derart dimensioniert ist, dass die der Aufprallkraft via den Support 5 entgegenwirkende Kraft bei diesem Flansch 14' gegenüber dem Rohrstück 8 variierbar ist.Within the scope of the invention, a separate flange 14' is attached to the
Beim vorliegenden Ausführungsbeispiel ist dieser Flansch 14' gegenüber dem Rohrstück 8 mit seinem Innendurchmesser verkleinert bzw. mit dem Aussendurchmesser vergrössert. Damit wird die der Aufprallkraft entgegenwirkende Kraft bei diesem Flansch 14' erhöht. Diese Dimensionierung kann je nach Anwendungsfall variiert werden und es könnten auch mehr als ein solcher Flansche 14' vorgesehen sein.In the present exemplary embodiment, this flange 14' is reduced in terms of its inside diameter or increased in terms of its outside diameter compared to the piece of
Die Fixierung des Ansatzes 4 im Kupplungsflansch 6 mit den Abscherbolzen 7 hat den Zweck zu verhindern, dass im normalen Betrieb der Support 5 im Bereich der Durchmessererweiterung 12 infolge von Vibrationen oder leichten Rückstössen instabil wird.The purpose of fixing the extension 4 in the
Bei einem Aufprall werden die Abscherbolzen 7 bei Erreichen einer bestimmten Aufprallkraft abgeschert, und der Support 5 wird freigegeben, damit sie ungehindert in den Verformungsbereich des Rohrstückes 8 eindringen kann und ihn aufweitet.In the event of an impact, the
Um zu verhindern, dass dieser Vorgang Risse und/oder Schwingungen des Rohres verursacht, ist es erfindungsgemäss vorgesehen, dass die Aufweitung des Rohrstücks 8 durch den Support 5 im Bereich einer plastischen Verformung stattfindet, wobei die Werkstoffe des Rohres und des Gleitrings 13 so aufeinander abgestimmt sind, dass beim Aufprall der Support 5 gegen die Innenseite des Rohrstücks 8 mit annähernd gleichmässiger Reibkraft entlanggleitet.In order to prevent this process from causing cracks and/or vibrations in the pipe, the invention provides for the
Zweckmässigerweise ist das Rohrstück 8 innenseitig beschichtet, vorteilhaft mit einer Grundfarbe grundiert, während der Support 5 mit dem Gleitring 13 aus einem gleitenden Werkstoff, vorzugsweise Sphäroguss (Grauguss), versehen ist.The
Durch diese Materialauswahl ist sichergestellt, dass bei einem Aufprall die Verformung des Rohrstücks 8 innerhalb bestimmter Aufprallkräfte weitgehend ruckfrei und ohne einen Kraftanstieg oder Kraftspitzen über den gesamten Verformungsbereich des Rohres stattfindet.This choice of material ensures that, in the event of an impact, the deformation of the
Das Rohrstück 8 ist an seinem vom Kupplungsflansch 6 abgekehrten Rohrende 14 offen und mündet dort in einen ebenfalls offenen Innenraum das nicht dargestellten Fahrzeugkastens, in den der Support 5 bei einer Frontalkollision je nach Masse und/oder Geschwindigkeit des aufprallenden Fahrzeugs gestossen wird.The
Die beschriebene passive Sicherheitseinrichtung kann sowohl in nur einer als auch in beiden Kupplungshälften der Kupplung eingebaut sein.The passive safety device described can be installed either in just one or in both halves of the clutch.
Die Erfindung ist mit dem erläuterten Ausführungsbeispiel ausreichend dargetan. Sie könnte aber noch durch andere Varianten erläutert sein. Im Prinzip könnte das Rohrstück mit einer Durchmessererweiterung als eine ringförmige Ausnehmung vorgesehen sein.The invention is sufficiently demonstrated with the illustrated embodiment. However, it could also be explained by other variants. In principle, the piece of pipe could be provided with an enlarged diameter as an annular recess.
Das Rohrstück mit dem Rohrende 14 könnte auch aus einem einstückigen Rohr hergestellt sein.The piece of pipe with the
