Description

Beschreibungdescription
Schienenfahrzeug zur Personenbeförderung, insbesondere für den NahverkehrRail vehicle for the transportation of people, in particular for local traffic
Die Erfindung betrifft ein Schienenfahrzeug zur Personenbeförderung, insbesondere für den Nahverkehr, das an zumindest einem seiner Enden mit Stoßverzehreinheiten versehen ist.The invention relates to a rail vehicle for the transportation of people, in particular for local traffic, which is provided with shock absorbing units at at least one of its ends.
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 arrange shock absorbing units (shock buffers) in the end region of rail vehicles, which include, for example, elastomer bodies or deformable hollow bodies made of sheet metal. Such devices can reduce part of the impact energy that occurs in collisions with similar vehicles or with road vehicles or when driving against a stationary obstacle.
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 to provide an innovative crumple zone with defined behavior in a rail vehicle of the generic type with regard to possible collisions.
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 absorbing units are supported in the longitudinal direction of the vehicle on a deformable, metallic foam-containing sandwich component which forms part of the floor of the driver's cab as a supporting structural element.
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 illustrated 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 Kupplungsarm 7a aufweist. 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.1 and 2 each show a perspective view of the lower region of the head section of a rail vehicle, which has a central buffer coupling 7 with an articulated coupling arm 7a. In contrast to FIGS. 1 and 2, the rail vehicle also shown in perspective in FIGS. 3 and 4 has a central buffer coupling 8 known from DE 195 13 386 A1, the linkage of which consists of elements 8a which interact like scissors.
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 Anticlim- bers 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 provided with shock absorbing units 1, which here are part of a so-called anti-limber, which also has a bumper 6 profiled on the front. The profile of this bumper 6 prevents the vehicle from climbing, particularly in the event of a collision with a similar vehicle. The shock absorbing units 1, which can be designed, for example, in accordance with the publication WO 98/38 438 and have at least one deformable section of a thick-walled plastic tube, are connected on the one hand to the bumper 6 and, on the other hand, are supported on a sandwich component 2 in the longitudinal direction of the vehicle.
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 sandwich component 2, which essentially consists of aluminum and a metallic foam, forms part of the floor 3 of the driver's cab 4 as a supporting structural element. In the exemplary embodiments, the overall length of the sandwich component 2 is limited to the area of the floor 3 which is below that in the driver's cab 4 , driver's console, not shown here. The sandwich component 2 is releasably connected only to middle end supports 5 of the vehicle structure.
Das Schienenfahrzeug nach der Erfindung hat vorteilhaft stets eine 3stufige Knautschzone mit definiertem Verhalten im Falle von Zusammenstößen, und zwar: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) 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.a) Smaller shocks occurring at speeds of up to approx. 8 km / h are not deformed by the - in particular in FIGS. 9 and 10 shown - shock absorption units 1, which deform plastically (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) 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.b) At speeds of up to about 17 km / h, the shock absorbing units 1 and additionally the sandwich component 2 (see FIGS. 7 and 8) deform, which therefore also serves to absorb the shock in addition to its load-bearing function. 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) 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.c) At speeds of up to approx. 32 km / h, a major accident can be assumed, in which, however, in addition to the shock absorbing units 1 and the sandwich component 2, only the middle end member 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 vollständig 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. Liste der BezugszeichenAs can be seen from FIGS. 1 and 2 or 3 and 4, the central buffer coupling 7 or 8 of the respective vehicle is arranged completely behind the front of the vehicle in the non-coupled position. In the coupled state of two vehicles, the 3-stage crumple zone described above is expanded by a spring and damping device, which is usually contained in the coupling arm 7a of the central buffer coupling 7 or is arranged downstream of the scissor elements 8a of the central buffer coupling 8. The respective rail vehicle then has a 4-stage crash behavior in the event of collisions. List of reference numbers
