Description

Die Erfindung betrifft ein Schienenfahrzeug zur Personenbeförderung, insbesondere für den Nahverkehr, das an zumindest einem seiner Enden mit Stoßverzehreinheiten versehen ist. Solche Fahrzeuge sind z.B. durch die DE-A1- 197 57 917 bekannt.The invention relates to a rail vehicle for passenger transport, in particular for local traffic, which has at least one end with shock absorbing units is provided. Such vehicles are e.g. through the DE-A1-197 57 917 known.

Es ist allgemein bekannt, im Endbereich von Schienenfahrzeugen Stoßverzehreinheiten (Stoßpuffer) anzuordnen, die beispielsweise Elastomerkörper oder deformierbare Hohlkörper aus Blech umfassen. Derartige Einrichtungen können einen Teil der Aufprallenergie abbauen, die bei Zusammenstößen mit gleichartigen Fahrzeugen oder mit Straßenfahrzeugen oder bei Fahrt gegen ein ortsfestes Hindernis auftritt.It is generally known to use shock absorbing units in the end region of rail vehicles Arrange (shock buffer), for example the elastomer body or include deformable hollow bodies made of sheet metal. Such facilities can dissipate some of the impact energy caused by collisions with similar vehicles or with road vehicles or when driving against one stationary obstacle occurs.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Schienenfahrzeug der gattungsgemäßen Art im Hinblick auf eventuell auftretende Zusammenstöße eine innovative Knautschzone mit definiertem Verhalten zu schaffen.The invention has for its object in a rail vehicle generic type with regard to possible collisions to create an innovative crumple zone with defined behavior.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Stoßverzehreinheiten in Fahrzeuglängsrichtung an einem deformierbaren, metallischen Schaum enthaltenden Sandwichbauteil abgestützt sind, das als tragendes Strukturelement einen Teilbereich des Fußbodens der Fahrerkabine bildet.This object is achieved in that the shock absorption units in the longitudinal direction of the vehicle on a deformable, metallic Foam-containing sandwich component are supported, which as a load-bearing Structural element forms part of the floor of the driver's cabin.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Im weiteren wird die Erfindung anhand von Ausführungsbeispielen näher beschrieben, die in der Zeichnung dargestellt sind.The invention is described in more detail below on the basis of exemplary embodiments, which are shown in the drawing.

Die Fig. 1 und 2 zeigen jeweils in perspektivischer Darstellung den unteren Bereich der Kopfpartie eines Schienenfahrzeuges, das eine Mittelpufferkupplung 7 mit einem gelenkig ausgeführten Kuppiungsarm 7a aufweist. 1 and 2 each show a perspective view of the lower area the head section of a rail vehicle, which has a central buffer coupling 7 with an articulated coupling arm 7a.

Unterschiedlich zu den Fig. 1 und 2 hat das in den Fig. 3 und 4 ebenfalls in der Perspektive dargestellte Schienenfahrzeug eine durch die DE 195 13 386 A1 bekannte Mittelpufferkupplung 8, deren Gestänge aus scherenartig zusammenwirkenden Elementen 8a besteht.Different from FIGS. 1 and 2, this also has in FIGS. 3 and 4 in the Perspective rail vehicle shown by DE 195 13 386 A1 known center buffer coupling 8, the linkage of which interact like scissors Elements 8a.

Die Fig. 5 bis 8 sind ergänzende Ansichten bzw. Schnittbilder zu den Fig. 1 und 2. Die Fig. 9 und 10 ergänzen die Fig. 3 und 4 entsprechend.5 to 8 are additional views or sectional views of FIGS. 1 and 2. FIGS. 9 and 10 supplement FIGS. 3 and 4 accordingly.

Das Schienenfahrzeug nach Fig. 1 und 2 bzw. nach Fig. 3 und 4 ist mit Stoßverzehreinheiten 1 versehen, die hier Bestandteil eines sogenannten Anticlimbers sind, der außerdem eine frontseitig profilierte Stoßstange 6 aufweist. Das Profil dieser Stoßstange 6 verhindert ein Aufklettern des Fahrzeuges insbesondere im Falle eines Zusammenstoßes mit einem gleichartigen Fahrzeug. Die Stoßverzehreinheiten 1, die beispielsweise entsprechend der Druckschrift WO 98/38 438 ausgeführt sein können und zumindest einen deformierbaren Abschnitt eines dickwandigen Kunststoffrohres aufweisen, sind einerseits mit der Stoßstange 6 verbunden und andererseits an einem Sandwichbauteil 2 in Fahrzeuglängsrichtung abgestützt.The rail vehicle according to FIGS. 1 and 2 or according to FIGS. 3 and 4 is with shock absorbing units 1 provided, which is part of a so-called anti-climber are, which also has a front profiled bumper 6. The Profile of this bumper 6 prevents climbing of the vehicle in particular in the event of a collision with a similar vehicle. The Shock absorbing units 1, which, for example, according to WO 98/38 438 can be performed and at least one deformable section have a thick-walled plastic tube are on the one hand with the Bumper 6 connected and on the other hand to a sandwich component 2 in the vehicle longitudinal direction supported.

Das im wesentlichen aus Aluminium und einem metallischen Schaum bestehende Sandwichbauteil 2 bildet als tragendes Strukturelement einen Teilbereich des Fußbodens 3 der Fahrerkabine 4. In den Ausführungsbeispielen ist die Baulänge des Sandwichbauteiles 2 auf den Bereich des Fußbodens 3 begrenzt, der unterhalb eines in der Fahrerkabine 4 befindlichen, hier nicht dargestellten Fahrerpultes liegt. Das Sandwichbauteil 2 ist lediglich an mittleren Abschlußträgern 5 der Fahrzeugstruktur lösbar angeschlossen.The essentially consisting of aluminum and a metallic foam Sandwich component 2 forms a partial area as a load-bearing structural element of the floor 3 of the driver's cab 4. In the exemplary embodiments, the Overall length of the sandwich component 2 limited to the area of the floor 3, the one below in the driver's cab 4, not shown here Driver's console is located. The sandwich component 2 is only on middle end beams 5 of the vehicle structure detachably connected.

Das Schienenfahrzeug nach der Erfindung hat vorteilhaft stets eine 3stufige Knautschzone mit definiertem Verhalten im Falle von Zusammenstößen, und zwar:

  • a) Bei Geschwindigkeiten bis ca. 8 km/h vorkommende kleinere Stöße werden allein durch die - insbesondere in den Fig. 9 und 10 nicht verformt gezeigten - Stoßverzehreinheiten 1 aufgenommen, die sich dabei plastisch verformen (siehe Fig. 5 und 6). Die Stoßverzehreinheiten 1 werden anschließend einfach durch neue Bauteile ersetzt. Das Fahrzeug selbst bleibt frei von Beschädigungen.
  • b) Bei Geschwindigkeiten bis etwa 17 km/h verformen sich die Stoßverzehreinheiten 1 und zusätzlich das Sandwichbauteil 2 (siehe Fig. 7 und 8), das also außer seiner tragenden Funktion auch dem Stoßverzehr dient. Auch in diesem Falle kann durch eine kleinere Reparatur mit Hilfe einfach austauschbarer Bauelemente die bestehende leichte Beschädigung des Fahrzeuges behoben werden.
  • c) Bei Geschwindigkeiten bis ca. 32 km/h ist von einem größeren Unfall auszugehen, bei dem jedoch außer den Stoßverzehreinheiten 1 und dem Sandwichbauteil 2 nur die mittleren Abschlußträger 5 der Fahrzeugstruktur verformt werden. Die äußeren Langträger und die eigentliche Fahrgastzelle bleiben jedoch auch bei einer derartig hohen Energieaufnahme unbeschädigt.
    • The rail vehicle according to the invention advantageously always has a 3-stage crumple zone with defined behavior in the event of collisions, namely:
  • a) Smaller shocks occurring at speeds of up to approx. 8 km / h are absorbed solely by the shock absorbing units 1, which are not shown deformed in particular in FIGS. 9 and 10 and which plastically deform (see FIGS. 5 and 6). The shock absorbing units 1 are then simply replaced by new components. The vehicle itself remains free from damage.
  • b) At speeds of up to approximately 17 km / h, the shock absorbing units 1 and additionally the sandwich component 2 (see FIGS. 7 and 8) deform, which in addition to its load-bearing function also serves to absorb the shock. In this case, too, the existing slight damage to the vehicle can be remedied by a minor repair with the aid of easily replaceable components.
  • c) At speeds of up to approx. 32 km / h, a major accident can be assumed, in which, however, apart from the shock absorbing units 1 and the sandwich component 2, only the middle end support 5 of the vehicle structure is deformed. However, the outer long beams and the actual passenger compartment remain undamaged even with such a high energy consumption.

    • Wie aus den Fig. 1 und 2 bzw. 3 und 4 ersichtlich ist, ist die Mittelpufferkupplung 7 bzw. 8 des jeweiligen Fahrzeuges in nicht gekuppelter Stellung voltständig hinter der Fahrzeugfront angeordnet. In gekuppeltem Zustand von zwei Fahrzeugen erweitert sich die oben beschriebene 3stufige Knautschzone durch eine Feder- und Dämpfungseinrichtung, die üblicherweise im Kupplungsarm 7a der Mittelpufferkupplung 7 enthalten oder den Scherenelementen 8a der Mittelpufferkupplung 8 nachgeordnet ist. Das jeweilige Schienenfahrzeug verfügt dann bei Zusammenstößen über ein insgesamt 4stufiges Crash-Verhalten. As can be seen from FIGS. 1 and 2 or 3 and 4, the central buffer coupling 7 or 8 of the respective vehicle in the uncoupled position arranged behind the vehicle front. Coupled state of two Vehicles expand the 3-stage crumple zone described above a spring and damping device, which is usually in the clutch arm 7a of the central buffer coupling 7 or the scissor elements 8a of the central buffer coupling 8 is subordinate. The respective rail vehicle has then in collisions via a total of 4 levels of crash behavior.
