Definitions
- the invention relates to an energy consumption device for a rail vehicle.
- rail vehicles in particular passenger rail vehicles, are equipped with defined crumple zones in which kinetic energy is converted into deformation and/or heat energy. This can reduce the stress on the people in the vehicle.
- large areas of the rail vehicle structure in the front area can be designed in such a way that they can absorb the deformation energy in a targeted manner, or special crash modules can be placed on the front and rear structure of the rail vehicle. The latter is advantageous because repairs after a collision are simplified by the easy accessibility of these crash modules.
- crash modules are also called energy dissipation devices, deformation modules, deformation elements, crumple elements or energy absorption elements.
- the direction of the acting deformation force is crucial. If this does not occur in the intended direction, for example, at an angle or not at the intended force application point, crash modules attached to the end of the vehicle in particular tend to only deform on one side. The result of this is that the free end of the crash module in question, which is usually provided with climbing protection, is tilted, significant transverse forces are generated, the energy absorption capacity of the crash module can no longer be fully exhausted and, moreover, the crash opponents are in danger because of the now slanted contact points to slide against each other.
- the invention is therefore based on the object of creating an energy dissipation device which, even in the event of a parallel displacement of the impacting collision force, for example in the event of a lateral offset of two rail vehicles colliding, not only deforms on one side, but also initiates the deformation evenly distributed over its entire circumference and so on in the further course can utilize their energy consumption capacity.
- an energy dissipation device for a rail vehicle which has a baffle plate, which is designed to absorb and forward impacting collision forces, a back plate, which is designed to attach the energy dissipation device to a vehicle structure, and at least two arranged between the baffle plate and the back plate
- buckling plates whereby the buckling plates are provided with a pre-deformation in the direction of a desired deformation direction, and the buckling plates are connected to one another with a tension-pressure means.
- An energy dissipation device comprises a back plate which is designed to attach the energy dissipation device to a vehicle structure.
- This attachment can preferably be designed to be detachable using screw connections.
- An inseparable connection is also advantageous for certain applications. The latter is particularly advantageous if the energy dissipation device is dimensioned such that its triggering leads to further damage to the vehicle structure and repairing the vehicle no longer makes economic sense.
- a baffle plate for absorbing collision forces introduced by a collision opponent is provided at a parallel distance from the back plate.
- This impact plate must be made so massive that it can be used during the collision even with massive collision opponents, such as those commonly used in the USA Locomotive front sides remain able to transfer the introduced forces as homogeneously and flatly as possible to the energy consumption device behind them.
- the baffle plate can be made either in one piece as a cast steel part or as a welded construction made of steel plates with internal honeycomb reinforcements.
- At least two buckling plates are arranged between the baffle plate and the back plate and connected to the baffle or back plate.
- These bending plates are designed as plate-shaped components and are aligned vertically in the installed position of the energy consumption device. They are equipped with a pre-deformation so that they deform in a predetermined manner when a deformation force introduced via the impact plate acts. It is particularly advantageous to design the bending plates as plates with a single bending point, so that the bending plates have a V-shaped course. In this way, the direction of deformation of the buckling plates is clearly specified. It is essential that the pre-deformations of the bending plates point in the same direction, since this is the only way to ensure that the deformation of one bending plate can also be transmitted to the other bending plates and that a deformation of these further bending plates is initiated.
- the buckling plates are connected to each other by means of a tension-compression means.
- a tension-pressure medium transmits both tensile and compressive forces without deforming itself worth taking into account.
- sufficiently thick rod-shaped components can be used that do not buckle even under pressure.
- This synchronization plate extends between the bending plates and is firmly connected to the bending plates.
- the synchronization plate is oriented parallel to the back plate and the baffle plate. It is particularly advantageous to provide the connection points of the synchronization plate with the bending plates at the position of the greatest pre-deformation of the bending plates, since the greatest possible deformation of the further bending plates can be achieved in this way.
- At least one shear-resistant connecting plate (support plate) between the back plate and the baffle plate, which prevents a parallel displacement of the baffle plate against the back plate.
- This support plate is to be designed as a plate-shaped component and is to be firmly connected to the impact plate and the back plate.
- the support plate can be arranged at the upper or lower limit of the energy dissipation device.
- a preferred embodiment of the invention provides for two support plates to be arranged, one at the top and one at the bottom, so that complete envelopment of the energy dissipation device can be achieved with additional side covers. In this way, the energy consumption device is better protected against contamination or corrosion.
- the energy dissipation device forms a substantially hollow, cuboid assembly, so that in a further development of the invention it is expedient to at least partially fill this cavity with further energy dissipation elements. As a result, the energy absorption capacity of the energy consumption device can be further increased.
- a preferred embodiment of the invention provides for energy dissipation elements to be arranged between the back plate and the baffle plate and to guide these through recesses in the tension-pressure means (synchronization plate).
- the energy dissipation elements can be connected either to the baffle plate or the back plate and the recesses in the synchronization plate must ensure sufficient collision-free mobility of the synchronization plate.
- further energy dissipation elements can be arranged on the tension pressure means (synchronization plate) itself.
- a front and a rear energy dissipation element is attached to the synchronization plate.
- the front energy dissipation element extends between the synchronization plate and the baffle plate, but does not touch them, but is at a certain distance from the baffle plate.
- the rear energy dissipation element extends between the synchronization plate and the back plate, but does not touch them, but is at a certain distance from the back plate.
- the mobility of the synchronization plate is not restricted at the beginning of the deformation process, it can therefore transmit the deformation of one bending plate to the other bending plates and as the deformation progresses, the distances between the rear and front energy absorption elements and the back or impact plate are overcome and the rear and front energy dissipation elements come into effect. From this point on in the deformation process, the synchronization plate's mobility is hindered, However, the ability to move the synchronization plate is no longer fully necessary.

- two buckling plates 5 are arranged between the back plate 4 and the baffle plate 3 and are each welded to the back plate 4 and the baffle plate 3.
- the buckling plates 5 have a pre-deformation in the form of a bend, whereby the bends of both bending plates 5 point in the same direction.
- the buckling plates 5 are connected by means of a tension-pressure means 6.
- the tension-pressure means 6 is designed as a plate-shaped component (synchronization plate) and welded to the buckling plates 5 at the point of greatest deformation.
- Fig.2 shows an example and schematic of an energy dissipation device during deformation.
- the energy dissipation device 1 is shown under the influence of a collision opponent 7.

- a partially advanced deformation is shown, in which part of the energy consumption device is already exhausted.
- the tension-pressure medium 6 causes a symmetrical deformation of the two buckling plates 5 and thus a parallel displacement of the impact plate 3 with respect to the back plate 4.

Description
Die Erfindung betrifft eine Energieverzehreinrichtung für ein Schienenfahrzeug.The invention relates to an energy consumption device for a rail vehicle.
Schienenfahrzeuge, insbesondere Passagierschienenfahrzeuge werden zur Verbesserung in Hinsicht auf die passive Sicherheit bei Zusammenstößen mit definierten Knautschzonen ausgestattet, in welchen kinetische Energie in Verformungs- und/oder Wärmeenergie umgewandelt wird. Dadurch können die Belastungen für die Personen im Fahrzeug reduziert werden. Zu diesem Zweck können einerseits großflächige Bereiche der Schienenfahrzeugstruktur im Stirnbereich so gestaltet werden, dass sie die Verformungsenergie gezielt aufnehmen können oder es werden spezielle Crashmodule auf die Front- und Heckstruktur des Schienenfahrzeugs aufgesetzt. Letzteres ist vorteilhaft, da eine Reparatur nach einem Zusammenstoß durch die leichte Zugänglichkeit dieser Crashmodule vereinfacht wird. Diese Crashmodule werden auch Energieverzehreinrichtungen, Verformungsmodule, Verformungselemente, Knautschelemente oder Energieaufnahmeelemente genannt. Für eine korrekte Funktion, d.h. eine möglichst vollständige Erschöpfung der Energieaufnahmekapazität einer Energieverzehreinrichtung ist die Richtung der einwirkenden Verformungskraft entscheidend. Tritt diese nicht in der vorgesehenen Richtung ein, beispielsweise schräg oder nicht am vorgesehenen Kraftangriffspunkt, so tendieren besonders an das Ende des Fahrzeugs angebrachte Crashmodule dazu, sich nur einseitig zu deformieren. Dieses hat zur Folge, dass sich das freie Ende des betreffenden Crashmoduls, das üblicherweise mit einem Aufkletterschutz versehen ist, schräg stellt, signifikante Querkräfte erzeugt werden, die Energieabsorptionsfähigkeit des Crashmoduls nicht mehr voll erschöpft werden kann und überdies die Crashgegner in Gefahr laufen, wegen der nunmehr schrägen Kontaktstellen aneinander abzugleiten.To improve passive safety in collisions, rail vehicles, in particular passenger rail vehicles, are equipped with defined crumple zones in which kinetic energy is converted into deformation and/or heat energy. This can reduce the stress on the people in the vehicle. For this purpose, large areas of the rail vehicle structure in the front area can be designed in such a way that they can absorb the deformation energy in a targeted manner, or special crash modules can be placed on the front and rear structure of the rail vehicle. The latter is advantageous because repairs after a collision are simplified by the easy accessibility of these crash modules. These crash modules are also called energy dissipation devices, deformation modules, deformation elements, crumple elements or energy absorption elements. For correct function, ie the most complete exhaustion of the energy absorption capacity of an energy consumption device, the direction of the acting deformation force is crucial. If this does not occur in the intended direction, for example, at an angle or not at the intended force application point, crash modules attached to the end of the vehicle in particular tend to only deform on one side. The result of this is that the free end of the crash module in question, which is usually provided with climbing protection, is tilted, significant transverse forces are generated, the energy absorption capacity of the crash module can no longer be fully exhausted and, moreover, the crash opponents are in danger because of the now slanted contact points to slide against each other.
Ein Beispiel einer Energieverzehreinrichtung aus dem Stand der Technik ist in der Veröffentlichung
Der Erfindung liegt daher die Aufgabe zugrunde, eine Energieverzehreinrichtung zu schaffen, welche auch bei einer Parallelverschiebung der einwirkenden Kollisionskraft, beispielsweise bei seitlichem Versatz zweier aufeinandertreffender Schienenfahrzeuge, nicht nur einseitig verformt, sondern die Deformation über ihren gesamten Umfang gleichmäßig verteilt einleitet und so im weiteren Verlauf ihre Energieverzehrkapazität ausschöpfen kann.The invention is therefore based on the object of creating an energy dissipation device which, even in the event of a parallel displacement of the impacting collision force, for example in the event of a lateral offset of two rail vehicles colliding, not only deforms on one side, but also initiates the deformation evenly distributed over its entire circumference and so on in the further course can utilize their energy consumption capacity.
Die Aufgabe wird durch eine Energieverzehreinrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand untergeordneter Ansprüche. Dem Grundgedanken der Erfindung nach wird eine Energieverzehreinrichtung für ein Schienenfahrzeug aufgebaut, welche eine Prallplatte, welche zur Aufnahme und Weiterleitung auftreffender Kollisionskräfte ausgebildet ist, eine Rückplatte, welche zur Befestigung der Energieverzehreinrichtung an einer Fahrzeugstruktur ausgebildet ist und mindestens zwei zwischen der Prallplatte und der Rückplatte angeordnete Knickplatten umfasst, wobei die Knickplatten mit einer Vorverformung in Richtung einer gewünschten Verformungsrichtung versehen sind, und wobei die Knickplatten untereinander mit einem Zug-Druckmittel verbunden sind.The task is solved by an energy consumption device with the features of claim 1. Advantageous refinements are the subject of subordinate claims. According to the basic idea of the invention, an energy dissipation device for a rail vehicle is constructed, which has a baffle plate, which is designed to absorb and forward impacting collision forces, a back plate, which is designed to attach the energy dissipation device to a vehicle structure, and at least two arranged between the baffle plate and the back plate Includes buckling plates, whereby the buckling plates are provided with a pre-deformation in the direction of a desired deformation direction, and the buckling plates are connected to one another with a tension-pressure means.
Dadurch ist der Vorteil erzielbar, bei einem Auftreffen einer Verformungskraft auf die Energieverzehreinrichtung außerhalb einer vorgesehenen Kraftrichtung ein teilweises, insb. einseitiges kollabieren der Energieverzehreinrichtung zu vermeiden. Tritt eine einseitige Verformung auf, so überträgt das Zug-Druckmittel Verformung der einen Knickplatte auf die jeweils andere Knickplatte und verformt diese so, dass die Prallplatte in Bezug auf die Rückplatte parallel verschoben wird.This makes it possible to achieve the advantage of avoiding a partial, especially one-sided, collapse of the energy dissipation device when a deforming force hits the energy dissipation device outside of an intended direction of force. If a one-sided deformation occurs, the tension-compression medium transfers deformation of one buckling plate to the other buckling plate and deforms it in such a way that the impact plate is displaced parallel to the back plate.
Eine erfindungsgemäße Energieverzehreinrichtung umfasst eine Rückplatte, welche zur Befestigung der Energieverzehreinrichtung an einer Fahrzeugstruktur ausgebildet ist. Diese Befestigung kann vorzugsweise lösbar mittels Schraubverbindungen gestaltet sein. Für bestimmte Einsatzzwecke ist auch eine unlösbare Verbindung vorteilhaft. Letzteres ist insbesondere vorteilhaft, wenn die Energieverzehreinrichtung so dimensioniert ist, dass ihr Auslösen ohnedies zu weiteren Schäden an der Fahrzeugstruktur führt und eine Reparatur des Fahrzeugs nicht mehr wirtschaftlich sinnvoll ist.An energy dissipation device according to the invention comprises a back plate which is designed to attach the energy dissipation device to a vehicle structure. This attachment can preferably be designed to be detachable using screw connections. An inseparable connection is also advantageous for certain applications. The latter is particularly advantageous if the energy dissipation device is dimensioned such that its triggering leads to further damage to the vehicle structure and repairing the vehicle no longer makes economic sense.
Eine Prallplatte zur Aufnahme von Kollisionskräften, welche durch einen Kollisionsgegner eingebracht werden, ist von der Rückplatte parallel beabstandet vorgesehen. Diese Prallplatte ist so massiv auszuführen, dass sie während des Kollisionsgeschehens auch bei massiven Kollisionsgegnern, wie beispielsweise bei den in den USA gebräuchlichen Lokomotivstirnseiten, in der Lage bleibt, die eingeleiteten Kräfte möglichst homogen und flächig auf die dahinter liegende Energieverzehreinrichtung zu übertragen. Die Prallplatte kann dabei entweder einstückig als Stahlgußteil oder als Schweißkonstruktion aus Stahlplatten mit inneren wabenförmigen Verstärkungen ausgeführt werden.A baffle plate for absorbing collision forces introduced by a collision opponent is provided at a parallel distance from the back plate. This impact plate must be made so massive that it can be used during the collision even with massive collision opponents, such as those commonly used in the USA Locomotive front sides remain able to transfer the introduced forces as homogeneously and flatly as possible to the energy consumption device behind them. The baffle plate can be made either in one piece as a cast steel part or as a welded construction made of steel plates with internal honeycomb reinforcements.
Zwischen der Prallplatte und der Rückplatte sind mindestens zwei Knickplatten angeordnet und mit der Prall- bzw. Rückplatte verbunden. Diese Knickplatten sind als plattenförmige Bauteile ausgeführt und in Einbaulage der Energieverzehreinrichtung vertikal ausgerichtet. Sie sind mit einer Vorverformung ausgestattet, sodass sie beim Einwirken einer über die Prallplatte eingeleiteten Verformungskraft sich in vorbestimmter Weise verformen. Dabei ist es besonders vorteilhaft, die Knickplatten als Platten mit einer einzelnen Biegestelle auszuführen, sodass die Knickplatten einen V-förmigen Verlauf aufweisen. Solcherart ist die Verformungsrichtung der Knickplatten eindeutig vorgegeben. Es ist wesentlich, dass die Vorverformungen der Knickplatten in dieselbe Richtung weisen, da nur so sichergestellt ist, dass die Verformung einer Knickplatte auch an die weiteren Knickplatten übertragen werden kann und eine Verformung dieser weiteren Knickplatten eingeleitet wird.At least two buckling plates are arranged between the baffle plate and the back plate and connected to the baffle or back plate. These bending plates are designed as plate-shaped components and are aligned vertically in the installed position of the energy consumption device. They are equipped with a pre-deformation so that they deform in a predetermined manner when a deformation force introduced via the impact plate acts. It is particularly advantageous to design the bending plates as plates with a single bending point, so that the bending plates have a V-shaped course. In this way, the direction of deformation of the buckling plates is clearly specified. It is essential that the pre-deformations of the bending plates point in the same direction, since this is the only way to ensure that the deformation of one bending plate can also be transmitted to the other bending plates and that a deformation of these further bending plates is initiated.
Die Knickplatten sind untereinander mittels eines Zug-Druckmittels verbunden. Ein Zug- Druckmittel überträgt sowohl Zug- als auch Druckkräfte, ohne sich selbst dabei berücksichtigenswert zu verformen. Dazu können beispielsweise ausreichend dicke stangenförmige Bauteile eingesetzt werden, welche auch unter Druckbelastung nicht ausknicken. Insbesondere ist es vorteilhaft, als Zug- Druckmittel ein plattenförmiges Bauteil einzusetzen, eine Synchronisationsplatte. Diese Synchronisationsplatte erstreckt sich zwischen den Knickplatte und ist mit den Knickplatten fest verbunden. Die Synchronisationsplatte ist dabei parallel zu der Rückplatte und der Prallplatte orientiert. Besonders vorteilhaft ist es, die Verbindungsstellen der Synchronisationsplatte mit den Knickplatten an der Position der größten Vorverformung der Knickplatten vorzusehen, da solcherart die größtmögliche Verformung der weiteren Knickplatten erzielbar ist.The buckling plates are connected to each other by means of a tension-compression means. A tension-pressure medium transmits both tensile and compressive forces without deforming itself worth taking into account. For this purpose, for example, sufficiently thick rod-shaped components can be used that do not buckle even under pressure. In particular, it is advantageous to use a plate-shaped component as a tension and pressure means synchronization plate. This synchronization plate extends between the bending plates and is firmly connected to the bending plates. The synchronization plate is oriented parallel to the back plate and the baffle plate. It is particularly advantageous to provide the connection points of the synchronization plate with the bending plates at the position of the greatest pre-deformation of the bending plates, since the greatest possible deformation of the further bending plates can be achieved in this way.
In weiterer Fortbildung der Erfindung ist es vorteilhaft, mindestens eine schubsteife Verbindungsplatte (Stützplatte) zwischen der Rückplatte und der Prallplatte vorzusehen, welche eine Parallelverschiebung der Prallplatte gegen die Rückplatte verhindert. Diese Stützplatte ist als plattenförmiges Bauteil auszuführen und mit der Prall- und der Rückplatte jeweils fest zu verbinden. Die Anordnung das Stützplatte kann dabei an der oberen oder der unteren Begrenzung der Energieverzehreinrichtung erfolgen. Eine bevorzugte Ausführungsform der Erfindung sieht vor, zwei Stützplatten, jeweils eine oben und unten anzuordnen, sodass mit zusätzlichen seitlichen Abdeckungen eine vollständige Umhüllung der Energieverzehreinrichtung erzielt werden kann. Solcherart ist die Energieverzehreinrichtung vor Verschmutzung oder Korrosion bessert geschützt.In a further development of the invention, it is advantageous to provide at least one shear-resistant connecting plate (support plate) between the back plate and the baffle plate, which prevents a parallel displacement of the baffle plate against the back plate. This support plate is to be designed as a plate-shaped component and is to be firmly connected to the impact plate and the back plate. The support plate can be arranged at the upper or lower limit of the energy dissipation device. A preferred embodiment of the invention provides for two support plates to be arranged, one at the top and one at the bottom, so that complete envelopment of the energy dissipation device can be achieved with additional side covers. In this way, the energy consumption device is better protected against contamination or corrosion.
Die erfindungsgemäße Energieverzehreinrichtung bildet eine im Wesentlichen hohle, quaderförmige Baugruppe, sodass es in weiterer Fortbildung der Erfindung zweckmäßig ist, diesen Hohlraum mit weiteren Energieverzehrelementen zumindest teilweise zu füllen. Dadurch kann die Energieaufnahmekapazität der Energieverzehreinrichtung weiter gesteigert werden.The energy dissipation device according to the invention forms a substantially hollow, cuboid assembly, so that in a further development of the invention it is expedient to at least partially fill this cavity with further energy dissipation elements. As a result, the energy absorption capacity of the energy consumption device can be further increased.
Eine bevorzugte Ausführungsform der Erfindung sieht vor, Energieverzehrelemente zwischen der Rückplatte und der Prallplatte anzuordnen und diese durch Ausnehmungen in dem Zug-Druckmittel (Synchronisationsplatte) zu führen. Die Energieverzehrelemente können dabei entweder mit der Prall- oder der Rückplatte verbunden sein und die Ausnehmungen ins der Synchronisationsplatte müssen eine ausreichende kollisionsfreie Bewegbarkeit der Synchronisationsplatte sicherstellen.A preferred embodiment of the invention provides for energy dissipation elements to be arranged between the back plate and the baffle plate and to guide these through recesses in the tension-pressure means (synchronization plate). The energy dissipation elements can be connected either to the baffle plate or the back plate and the recesses in the synchronization plate must ensure sufficient collision-free mobility of the synchronization plate.
In weiterer Fortbildung der Erfindung können an dem Zug-Druckmittel (Synchronisationsplatte) selbst weiter Energieverzehrelemente angeordnet werden. Dabei wird an der Synchronisationsplatte ein vorderes und ein hinteres Energieverzehrelement befestigt. Das vordere Energieverzehrelement erstreckt sich zwischen der Synchronisationsplatte und der Prallplatte, berührt diese jedoch nicht, sondern weist einen bestimmten Abstand zu der Prallplatte auf. Das hintere Energieverzehrelement erstreckt sich zwischen der Synchronisationsplatte und der Rückplatte, berührt diese jedoch nicht, sondern weist einen bestimmten Abstand zu der Rückplatte auf. Solcherart ist die Beweglichkeit der Synchronisationsplatte zu Beginn des Verformungsvorgangs nicht eingeschränkt, sie kann somit die Verformung einer Knickplatte an die weiteren Knickplatten übermitteln und bei weiterem Fortschreiten der Verformung werden die Abstände zwischen dem hinteren und vorderen Energieverzehrelementen und der Rück- bzw. Prallplatte überwunden und die hinteren und vorderen Energieverzehrelemente geraten in Wirkung. Ab diesem Zeitpunkt des Verformungsgeschehens wird die Synchronisationsplatte in ihrer Beweglichkeit zwar behindert, jedoch ist die Verschiebbarkeit der Synchronisationsplatte nun auch nicht mehr in vollem Umfang erforderlich.In a further development of the invention, further energy dissipation elements can be arranged on the tension pressure means (synchronization plate) itself. A front and a rear energy dissipation element is attached to the synchronization plate. The front energy dissipation element extends between the synchronization plate and the baffle plate, but does not touch them, but is at a certain distance from the baffle plate. The rear energy dissipation element extends between the synchronization plate and the back plate, but does not touch them, but is at a certain distance from the back plate. In this way, the mobility of the synchronization plate is not restricted at the beginning of the deformation process, it can therefore transmit the deformation of one bending plate to the other bending plates and as the deformation progresses, the distances between the rear and front energy absorption elements and the back or impact plate are overcome and the rear and front energy dissipation elements come into effect. From this point on in the deformation process, the synchronization plate's mobility is hindered, However, the ability to move the synchronization plate is no longer fully necessary.
