Stand der Technik State of the art
Zur Verbesserung des Verformungsverhaltens von To improve the deformation behavior of
Schienenfahrzeugen bei Zusammenstößen werden häufig Rail vehicles in collisions become common
Crashzonen eingebaut. Diese Crashzonen, bzw. Verformungszonen sollen die Aufprallenergie aufnehmen, wobei definiert verformbare Knautschzonen die Aufprallenergie in Crash zones installed. These crash zones or deformation zones are intended to absorb the impact energy, with deformable crumple zones defining the impact energy in
Verformungsenergie wandeln und dabei die Belastungen für die Personen im Fahrzeug minimieren. Transforming deformation energy while minimizing the strain on people in the vehicle.
Zu diesem Zweck können einerseits großflächige Bereiche der Schienenfahrzeugstruktur so gestaltet werden, dass sie die Verformungsenergie gezielt aufnehmen können oder es werden spezielle Crashmodule auf die Front- bzw. Heckstruktur des Schienenfahrzeugs aufgesetzt. Letztere Ausführungsform ist vorteilhaft, da eine Reparatur nach einem Zusammenstoß durch die leichte Zugänglichkeit dieser Crashmodule vereinfacht wird. Zusammenstöße zwischen Schienenfahrzeugen erfolgen im Wesentlichen in Richtung der Fahrzeuglängsachse, allenfalls kann ein Niveauunterschied, beispielsweise durch  For this purpose, on the one hand large areas of the rail vehicle structure can be designed so that they can absorb the deformation energy targeted or special crash modules are placed on the front or rear structure of the rail vehicle. The latter embodiment is advantageous because repair after a collision is facilitated by the easy accessibility of these crash modules. Collisions between rail vehicles take place substantially in the direction of the vehicle longitudinal axis, at most, a level difference, for example by
unterschiedliche Beladungszustände der kollidierenden different loading conditions of the colliding
Fahrzeuge zu einem sogenannten Aufreiten führen. Bei Vehicles lead to a so-called ride on. at
Schienenfahrzeugen, welche einem erhöhten Risiko eines Rail vehicles, which increase the risk of
Zusammenstoßes mit anderen Hindernissen als einem weiteren Schienenfahrzeug besteht (insbesondere Straßenbahnen) , stellt sich ein besonderes Problem. Es ist ein wesentlich breiteres Spektrum von Kollisionsszenarien abzudecken, wobei einseitig versetzte und schräge Kollisionen von herkömmlichen Clash with other obstacles than another Rail vehicle exists (especially trams), poses a particular problem. It covers a much wider range of collision scenarios, with unidirectional and oblique collisions of conventional
Knautschzonen bzw. Crashmodulen, die im Wesentlichen auf Kollisionen in Längsrichtung hin ausgelegt sind, nur Crumple zones or crash modules, which are designed essentially for collisions in the longitudinal direction, only
unbefriedigend beherrscht werden. Konventionelle, für longitudinale Zusammenstöße ausgelegte Crashmodule können diese schräge Belastung oft nicht zufriedenstellend be mastered unsatisfactory. Conventional crash modules designed for longitudinal collisions can often not satisfy this oblique load satisfactorily
aufnehmen, da dabei eine Biege- und Schubbeanspruchung an diesen Crashmodulen auftritt, unter der das betroffene As this results in a bending and shear stress on these crash modules, under which the affected
Crashelement ohne Vorkehrungen zur Querabstützung seitlich wegknicken wird. Eine entsprechende Auslegung der bekannten Crashelemente in einer Art, dass sie sowohl longitudinale als auch schräge Kollisionen gleichermaßen gut verarbeiten können, würde zu extrem aufwendigen, komplizierten und schweren Crashelementen führen, welche für den Einsatz an Schienenfahrzeugen nicht geeignet sind. Crash element without precautions to lateral support will buckle sideways. A corresponding design of the known crash elements in a way that they can handle equally well both longitudinal and oblique collisions, would lead to extremely complex, complicated and heavy crash elements, which are not suitable for use on rail vehicles.
Die Norm EN 15277 fordert für Straßenbahnfahrzeuge den  The standard EN 15277 calls for tram vehicles
Nachweis eines Zusammenstoßes mit einem baugleichen Fahrzeug mit 15km/h bei 40mm vertikalen Versatz und einen Zusammenstoß mit einem unter 45 Grad schräggestellten ebenen Hindernis von 3 Tonnen bei einer Geschwindigkeit von 25km/h (Kollisions- Szenario Zug gegen Leicht-LKW an einer Straßenkreuzung) . Evidence of a collision with a similar vehicle at 15km / h at 40mm vertical offset and a collision with a 3 degree flat obstacle tilted at 45 degrees at a speed of 25km / h (collision scenario train vs. light truck at a road intersection).
Somit sind anders geartete Zusammenstöße, beispielsweise mit Schienenfahrzeugen anderer Bauart, großen LKWs mit hohen Ladebordkanten oder Zusammenstöße bei einer Kurvenfahrt nicht von den Normerfordernissen abgedeckt. Darstellung der Erfindung Thus, other types of collisions, such as with rail vehicles of other types, large trucks with high tailboards or collisions when cornering not covered by the standard requirements. Presentation of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, ein The invention is therefore based on the object

Wagenkastens ausgerichtet sind und jeweils an einem ihrer Enden mit dem Wagenkasten verbunden sind, und wobei der Kollisionsrahmen die dem Wagenkasten abgewandten Enden der Verformungselemente verbindet und bogenförmig um die Car body are aligned and are each connected at one of its ends to the car body, and wherein the collision frame connects the car body facing away from the ends of the deformation elements and arcuately to the
Frontstruktur des Wagenkastens angeordnet ist, und wobei die A-Säulen jeweils zwischen dem Wagenkasten und dem Front structure of the car body is arranged, and wherein the A-pillars each between the car body and the
Kollisionsrahmen verlaufen und mit dem Kollisionsrahmen fest verbunden sind. Collision frame run and are firmly connected to the collision frame.
Dadurch ist der Vorteil erzielbar, ein Schienenfahrzeug mit Kollisionseigenschaften ausstatten zu können, die auch im Fall von schrägen Zusammenstößen, sowie insbesondere bei Zusammenstößen mit nicht baugleichen Fahrzeugen (andere Schienenfahrzeugmodelle, Lastkraftwagen, etc.) eine As a result, the advantage can be achieved to equip a rail vehicle with collision properties, even in the case of oblique collisions, and in particular in collisions with non-identical vehicles (other rail vehicle models, trucks, etc.) a

(Überlebenskäfig) geschaffen. Dieser ist bei Kollisionen mit hohen Hindernissen (Lastkraftwagen) vorteilhaft, da (Survival cage) created. This is in collisions with high obstacles (trucks) advantageous because
insbesondere moderne Straßenbahnen ein sehr niedriges especially modern trams a very low
Fußbodenniveau aufweisen, der Fahrzeugführerplatz also wesentlich fahrbahnnäher angeordnet ist. Durch die Verbindung der A-Säulen mit dem Kollisionsrahmen werden Having floor level, the driver's seat is thus arranged much closer to the road. By connecting the A-pillars with the collision frame
Kollisionskräfte, die in die A-Säulen eingeleitet werden in den Verformungselementen aufgenommen, die A-Säulen somit von der alleinigen Energieabsorption entlastet.  Collision forces that are introduced into the A-pillars are absorbed in the deformation elements, thus relieving the A-pillars of the sole energy absorption.
Erfindungsgemäß wird eine Verformungszone aufgebaut, welche einen Kollisionsrahmen umfasst. Dieser Kollisionsrahmen weist eine bogenförmige Struktur auf, welcher horizontal vor der Front des Wagenkastens angeordnet ist. Dabei kann der Bogen auch aus einzelnen geraden Segmenten aufgebaut sein. Der Kollisionsrahmen ist mittels einer Mehrzahl an According to the invention, a deformation zone is built up, which comprises a collision frame. This collision frame has an arcuate structure, which is arranged horizontally in front of the front of the car body. In this case, the arc can also be constructed of individual straight segments.

Components are connected. This deformation zone of A-pillars, Collision frame and deformation elements on the one hand forms a stable survival space for the driver, on the other hand an energy-dissipating zone.
Es ist besonders vorteilhaft, die Verformungszone als It is particularly advantageous to use the deformation zone as
Baugruppe auszuführen, welche getrennt vom Wagenkasten herstellbar ist und sie mit Mitteln zur lösbaren Befestigun an einem Wagenkasten auszustatten. Dadurch ist der Vorteil erzielbar, eine rasche Reparatur des Fahrzeugs durch Execute assembly, which is manufactured separately from the car body and equip them with means for releasably Befestigun to a car body. As a result, the advantage can be achieved, a rapid repair of the vehicle by

Weiters ist es empfehlenswert, die Fahrzeugspitze mit einer Aufreitsicherung (Anticlimber) auszustatten. Dadurch ist der Vorteil erzielbar, bei einer Kollision mit einem baugleichen ebenfalls mit einer Aufreitsicherung ausgestatteten Fahrzeug das sehr gefährliche sogenannte Aufreiten verhindern zu können, welches zu einer völligen Zerstörung der Furthermore, a deformation zone according to the invention also protects against a collision during cornering, whereas conventional deformation zones offer little or no protection.

Alternatively, the deformation elements may also be made by other technologies, e.g. as metal foam elements
ausgeführt werden. be executed.

Kollision eines Schienenfahrzeugs mit einem Lastkraftwagen in einer Seitenansicht. Es ist ein Kollisionsszenario zwischen einem Schienenfahrzeug 1 und einem Lastkraftwagen 9 Collision of a rail vehicle with a truck in a side view. It is a collision scenario between a rail vehicle 1 and a truck 9
dargestellt. Das Schienenfahrzeug 1 ist wie in den Fig. 1 bis 3 gezeigt aufgebaut. Von dem Lastkraftwagen 9 ist nur ein Rahmen einer Ladefläche dargestellt, da dies einerseits der stabilste Bauteil eines Lastkraftwagens ist und eine shown. The rail vehicle 1 is constructed as shown in FIGS. 1 to 3. Of the trucks 9 only one frame of a cargo area is shown, since this one hand the most stable component of a truck is and a
Kollision mit diesem Rahmen eines der häufigsten Collision with this framework one of the most common
Kollisionsszenarien ist. Der Zusammenstoß findet unter einem Winkel von ca. 45 Grad zur Längsachse des Schienenfahrzeugs statt. Die A-Säule 4 nimmt die Kollisionsenergie auf und wandelt sie teilweise in Verformungsarbeit in sich selbst, andererseits leitet sie die Kollisionsenergie in die Collision scenarios is. The collision takes place at an angle of approximately 45 degrees to the longitudinal axis of the rail vehicle. The A-pillar 4 absorbs the collision energy and converts it partially into deformation work in itself, on the other hand, it passes the collision energy in the
Verformungselemente 3. Ohne die A-Säule wäre der dargestellte Zusammenstoß für den Fahrzeugführer sehr gefährlich, da die Ladefläche des Lastkraftwagens 9 ungehindert in den Deformation elements 3. Without the A-pillar the collision would be very dangerous for the driver, since the back of the truck 9 in the unhindered
Fahrzeugführerraum eindringen könnte . Could penetrate driver's cab.
Fig.9 zeigt beispielhaft und schematisch eine schräge 9 shows an example and schematically an oblique
Kollision eines Schienenfahrzeugs mit einem Lastkraftwagen in einer Schrägansicht. Es ist das Kollisionsszenario aus Fig. 8 in einer Schrägansicht dargestellt. Fig. 9 zeigt das Collision of a rail vehicle with a truck in an oblique view. The collision scenario from FIG. 8 is shown in an oblique view. Fig. 9 shows that
Ansprechen der linken Verformungselemente 3 sowie ein leichtes Ansprechen der in Fahrzeuglängsrichtung orientierten Verformungselemente 3. Ein Schienenfahrzeug ohne eine erfindungsgemäße Verformungszone könnte auch bei einer Response of the left deformation elements 3 and a slight response of the oriented in the vehicle longitudinal direction deformation elements 3. A rail vehicle without a deformation zone according to the invention could also in a
Ausstattung mit konventionellen Verformungselementen bei einem solchen Zusammenstoß praktisch kaum Aufprallenergie absorbieren, da die konventionellen Verformungselemente ausknicken und ihre energiedissipierene Eigenschaft verlieren würden . Equipment with conventional deformation elements in such a collision absorb virtually no impact energy because the conventional deformation elements buckle and lose their energy-dissipating property.
