Die Erfindung betrifft eine Kollisionsschutzeinrichtung für Schienenfahrzeuge nach dem Oberbegriff des Anspruchs 1.The invention relates to a collision protection device for rail vehicles according to the preamble of claim 1.

Aus der DE 198 17 861 A1 ist eine Kollisionsschutzeinrichtung für Schienenfahrzeuge bekannt, die eine Mittelpufferkupplung mit Anlenkung über Abreißelemente im Untergestellvorbau, einen Führungsschacht, einen Unterfahrschutz und Energieabsorptionselemente aufweist.

Die Energieabsorptionselemente sind seitlich der Mittelpufferkonstruktion angeordnet und großflächig am Kopfträger und an der Rammschutzkonstruktion abgestützt. Beim Zusammenstoß mit Schienenfahrzeugen, die mit Seitenpuffern ausgerüstet sind, werden die Energieabsorptionselemente vorwiegend lokal im Bereich der eindringenden Seitenpuffer in Abhängigkeit vom Verformungswiderstandes verformt. Unterhalb vom Kopfträger bzw. von den Energieabsorptionselementen ist ein Unterfahrschutz in Wirkverbindung mit dem Kopfträger und der Rammschutzkonstruktion angeordnet, dessen Vorderkante gegenüber der Vorderkante der Energieabsorptionselemente mindestens um das Maß der vorgegebenen Stauchlänge der Energieabsorptionselemente zurückgesetzt ist.A collision protection device for rail vehicles is known from DE 198 17 861 A1, which has a central buffer coupling with articulation via tear-off elements in the underframe stem, a guide shaft, an underrun protection and energy absorption elements. In this case, the vehicle forward projecting center buffer coupling in the event of a collision after exposure to impact energy, which exceeds the energy consumption of the elastic elements to solve the tear-off elements of the undercarriage and led back to move. The energy absorption elements are arranged laterally of the central buffer construction and supported over a large area on the head support and on the impact protection construction. When colliding with rail vehicles equipped with side buffers, the energy absorbing elements are deformed mainly locally in the area of the penetrating side buffers depending on the deformation resistance. Underneath the head support or the energy absorption elements, an underrun protection is arranged in operative connection with the head support and the impact protection construction whose front edge is set back from the front edge of the energy absorption elements by at least the extent of the predetermined compression length of the energy absorption elements.

Aus der DE 198 17 860 A1 ist eine Sicherheitseinrichtung für Fahrzeugführer von Schienenfahrzeugen bekannt, die aus einer dem Kopfträger vorgelagerten Kollisionsschutzeinrichtung bekannter Bauart, einer am Kopfträger anschließenden Knautschzone im Bereich des Führerraumes, einem Führerpult, einem Sitzgestell und einem Führersitz besteht. Der Kopfträger, die Rommschutzkonstruktion, das Führerpult, das Sitzgestell und der Fahrersitz stehen in derartiger Wirkverbindung miteinander, dass sie bei Deformation der Knautschzone ihre Position zueinander nicht in einer den Fahrzeugführer gefährdenden Weise verändern. Der Kopfträger, die Rammschutzkonstruktion, das Führerpult, das Sitzgestell und der Führersitz sind dazu derart miteinander verbunden, dass die genannten Bauteile bei Deformation der Knautschzone gemeinsam in Richtung Fahrgastraum verschoben werden. Das Sitzgestell und der Führersitz sind gegenüber dem Höhenniveau der Knautschzone soweit angehoben, dass sich einerseits die Knautschzone unterhalb des Führersitzes ungehindert verformen kann und andererseits eine ungehinderte Längsverschiebung zwischen Sitzgestell und Knautschzone ermöglicht wird. Der Führersitz ist in einer Ausgestaltung gegenüber dem Führerpult derart begrenzt verschiebbar vorgesehen, dass der Fahrzeugführer nicht zwischen Führerpult und Führersitz eingeklemmt werden kann.From DE 198 17 860 A1 discloses a safety device for drivers of rail vehicles is known, which consists of a head carrier upstream collision protection device of known design, one of the head carrier Crumple zone in the area of the driver's compartment, a driver's desk, a seat frame and a driver's seat consists. The head support, the noise protection construction, the driver's desk, the seat frame and the driver's seat are in such operative connection with each other that they do not change their position relative to each other in a deformation endangering the driver. The head carrier, the Rammschutzkonstruktion, the driver's desk, the seat frame and the driver's seat are connected to each other in such a way that the said components are moved together with deformation of the crumple zone towards the passenger compartment. The seat frame and the driver's seat are so far raised compared to the height level of the crumple zone, that on the one hand deform the crumple zone underneath the driver's seat unhindered and on the other hand, an unhindered longitudinal displacement between the seat frame and crumple zone is made possible. The driver's seat is in such a limited slidably provided in an embodiment relative to the driver's desk, that the driver can not be trapped between the driver's desk and driver's seat.

Der Erfindung liegt die Aufgabe zugrunde, eine Kollisionsschutzeinrichtung der eingangs genannten Art derart weiterzuentwickeln, dass einerseits der Kollisionsschutz von Schienenfahrzeugen, die mit einer Mittelpufferkupplung ausgerüstet sind, im Falle eine Kollision mit Schienenfahrzeugen mit die mit Seitenpuffern versehen sind, verbessert ist und andererseits der Arbeitsraum des Fahrzeugführers, insbesondere sein direkter Arbeitsplatz, gegen den Fahrzeugführer gefährdende Verformungen im Führerstandsbereich, hervorgerufen durch übergroße Stoßenergien, effektiver geschützt ist.The invention has the object of providing a collision protection device of the type mentioned in such a way that on the one hand the collision protection of rail vehicles, which are equipped with a central buffer, in case of collision with rail vehicles with side buffers are improved, and on the other hand, the working space of Driver, in particular his direct workplace, against the driver dangerous deformation in the cab area, caused by oversized impact energy is effectively protected.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.This object is achieved by the features of claim 1.

Die Kollisionsschutzeinrichtung für Schienenfahrzeuge weist Energieabsorptionselemente 1 auf, die beidseitig der Mittellängsachse des Schienenfahrzeuges im Bereich der Seitenpuffer 2 von Vollbahnen angeordnet sind und an einer löngsbelastbaren Abstützung 3 der Fahrzeugstruktur abgestützt sind.The collision protection device for rail vehicles has energy absorption elements 1, which are arranged on both sides of the central longitudinal axis of the rail vehicle in the region of the side buffers 2 of full tracks and are supported on a löngsbelastbaren support 3 of the vehicle structure.

Das Energieabsorptionselement 1 ist als nach vorn in Stoßrichtung offener Topf 1a ausgebildet, welcher mit energieabsorbierendem Werkstoff 4 gefüllt ist. Der Topf 1a ist über die Abstützung 3 fest mit einem Druckstück 5 verbunden, welches längsverschieblich gegenüber dem Wagenkasten 6 mit einer zweiten Stufe 7 zur Absorption von zusätzlicher Deformationsenergie verbunden ist bzw. in Wirkverbindung steht. Diese zweite Stufe 7 ist dazu ausgelegt, nach Aufzehren des Energieabsorptionsvermögens des Energieverzehrelementes 1 und nach Überschreiten einer vorgegebenen Längskraft zusätzliche Deformationsenergie aus dem Längsstoß aufzunehmen und abzubauen.The energy absorbing member 1 is formed as a pot 1a open forward in the impact direction and filled with energy absorbing material 4. The pot 1a is connected via the support 3 fixed to a pressure piece 5, which is longitudinally displaceable relative to the car body 6 connected to a second stage 7 for absorbing additional deformation energy or is in operative connection. This second stage 7 is designed to absorb and dissipate additional deformation energy from the longitudinal joint after consumption of the energy absorption capacity of the energy dissipation element 1 and after exceeding a predetermined longitudinal force.

An dem Druckstück 5 sind weiterhin die Einrichtungen für den Fahrzeugführer einschließlich Fahrzeugführersitz 8 befestigt, die zusammen mit dem Druckstück 5 ins Fahrzeuginnere längsverschiebbar ausgebildet und angeordnet sind.At the pressure piece 5, the facilities for the driver including driver's seat 8 are further attached, which are formed longitudinally displaceable together with the pressure piece 5 in the vehicle interior and arranged.

Der Topf 1a weist eine Leitvorrichtung 9 als Einführhilfe auf. Die Leitvorrichtung 9 ist zweckmäßig, wie in Fig. 3 dargestellt, als Trichter ausgebildet. Der Mantel 10 des Topfes 1a ist ausreichend belastbar ausgebildet, derart, dass eine Längsführung gebildet ist, womit ein Querausweichen des Puffertellers eines eindringenden Seitenpuffers 2 und damit ein seitliches Ausweichen oder ein Aufklettern der kollidierenden Schienenfahrzeuge verhindert bzw. mindestens erheblich erschwert ist.The pot 1a has a guide device 9 as an insertion aid. The guide device 9 is expedient, as shown in Fig. 3, designed as a funnel. The jacket 10 of the pot 1a is formed sufficiently strong, such that a longitudinal guide is formed, whereby a transverse deflection of the buffer plate of a penetrating side buffer 2 and thus a lateral evasion or climbing the colliding rail vehicles prevented or at least considerably more difficult.

Der Topf 1a und/oder der in diesem eingefüllte, energieabsorbierende Werkstoff 4 kann vorteilhaft einen sich in Stoßrichtung vergrößernden Querschnitt aufweisen. Mit einer solchen Bauart wird erreicht, dass der Pufferteller beim Stoß zunächst auf einen kleineren Querschnitt auftrifft und in Stoßrichtung mit wachsendem Querschnitt eine Kennlinie mit steigendem Kraftverlauf gegeben ist.The pot 1a and / or the energy-absorbing material 4 filled therein can advantageously have a cross-section which increases in the impact direction. With such a design is achieved that the buffer plate at impact initially impinges on a smaller cross section and is given in the direction of impact with increasing cross section a curve with increasing force curve.

Dieser vorgenannte, prinzipielle Effekt ist auch bei einer in Fig. 2 gezeigten Variante mit Teilüberdeckung des Puffertellers und des Anfangsquerschnitts des Werkstoffs 4 gegeben. Diese Variante ist für Schienenfahrzeuge, insbesondere für Stadt- oder Regionalbahnen, mit sich nach vorn verjüngender Fahrzeugnase bzw. Querschnittsbreite geeignet, bei denen die Fahrzeugstirnseite schmaler als der gegenseitige Abstand der Seitenpuffer 2 der Vollbahnen ausgeführt ist.This aforementioned, principal effect is also given in a variant shown in Fig. 2 with partial coverage of the buffer plate and the initial cross-section of the material 4. This variant is suitable for rail vehicles, in particular for urban or regional railways, with forwardly tapering vehicle nose or cross-sectional width, in which the vehicle front side is made narrower than the mutual distance of the side buffers 2 of the full webs.

Falls der Mantel 10 des Topfes 1a nicht wesentlich größer als die Festigkeit des Werkstoffes ausgebildet wird, muss das gegenseitige Querausweichen oder Aufklettern der auffahrenden Schienenfahrzeuge anderweitig sichergestellt werden. Dazu stehen allerdings bekannte Kletterschutzeinrichtungen aus dem Stand der Technik zur Verfügung (z. B. DE 32 28 942 A1, US 3,197,039 oder US 2,802,581).If the shell 10 of the pot 1a is not formed substantially larger than the strength of the material, the mutual Querausweichen or climbing the ramped rail vehicles must be ensured otherwise. However, known climbing protection devices of the prior art are available for this purpose (eg DE 32 28 942 A1, US Pat. No. 3,197,039 or US Pat. No. 2,802,581).

Der Werkstoff 4 des Energieabsorptionselements 1 ist als fester Werkstoff vorgesehen. Dieser Werkstoff 4 kann aus dem Vollen geschnitten werden und im Topf 1a bzw. am Mantel 10 befestigt werden, z.B. durch Klebetechniken.The material 4 of the energy absorption element 1 is provided as a solid material. This material 4 can be cut from the solid and fixed in the pot 1a or on the shell 10, e.g. by adhesive techniques.

Gestalterisch kann der Bereich der Öffnung des Energieabsorptionselementes 1 bzw. des Topfes 1a zum Ein- bzw. Aufbringen eines Leuchtmittels genutzt werden.In terms of design, the region of the opening of the energy absorption element 1 or of the pot 1a can be used for insertion or application of a light source.

In den Figuren 4 bis 6 sind Prinzipskizzen der erfindungsgemäßen Kollisionsschutzeinrichtung mit Darstellung der zweiten Stufe 7 der Kollisionsschutzeinrichtung in Seitenansicht im Schnitt dargestellt.In the figures 4 to 6 are schematic diagrams of the collision protection device according to the invention with representation of the second stage 7 of the collision protection device in side view in section.

Fig.4 zeigt den Beginn der Beaufschlagung der topfartigen Energieabsorptionselemente 1 durch die Seitenpuffer 2 eines zweiten Schienenfahrzeuges. Fig. 5 zeigt eine Darstellung der Kollisionsschutzeinrichtung nach Eindringen der Seitenpuffer 2 in die Energieabsorptionselemente 1 und den Beginn des Ansprechens der zweiten Stufe 7 zur Energieabsorption von zusätzlicher Deformationsenergie. Fig. 6 zeigt die Kollisionsschutzeinrichtung gemäß der Fig. 5 nach dem Ansprechen der zweiten Stufe 7 zur Absorption von Deformationsenergie mit längsverschobenem Fahrzeugführersitz 8.4 shows the beginning of the loading of the pot-like energy absorption elements 1 through the side buffers 2 of a second rail vehicle. Fig. 5 shows a representation of the collision protection device after penetration of the side buffer 2 in the energy absorbing elements 1 and the beginning of the response of the second stage 7 for energy absorption of additional deformation energy. FIG. 6 shows the collision protection device according to FIG. 5 after the response of the second stage 7 for absorption of deformation energy with longitudinally displaced vehicle driver's seat 8.

Bei einer Kollision des erfindungsgemäß ausgerüsteten Schienenfahrzeugs mit einem zweiten Schienenfahrzeug mit Seitenpuffern 2 kommen die Pufferteller der Seitenpuffer 2 an den mit ihnen im wesentlichen axial fluchtenden Energieabsorptionselementen 1 bzw. Töpfe 1a zur Anlage. Beim weiteren Eindringen der Seitenpuffer 2 in die Töpfe 1a wird durch die Deformation des in den Töpfen 1a angeordneten energieabsorbierenden Werkstoffs 4 Stoßenergie abgebaut, wobei eine unkontrollierte Verformung des vorderen Bereichs des erfindungsgemäß ausgerüsteten Schienenfahrzeuges weitgehend verhindert wird.In a collision of the inventively equipped rail vehicle with a second rail vehicle with side buffers 2, the buffer plates of the side buffers 2 come to the substantially axially aligned with them energy absorption elements 1 and pots 1a to the plant. Upon further penetration of the side buffers 2 into the pots 1a, shock energy is dissipated by the deformation of the energy-absorbing material 4 arranged in the pots 1a, whereby an uncontrolled deformation of the front region of the rail vehicle equipped according to the invention is largely prevented.

Nach Aufzehren des Absorptionsvermögens und des zur Verfügung stehenden Verformungsweges des Energieverzehrelementes 1 spricht die zweite Stufe 7 der Kollisionsschutzeinrichtung an. Diese zweite Stufe 7 ist - wie bereits eingangs der Beschreibung erwähnt - dazu ausgelegt, nach Überschreiten einer vorgegebenen Längskraft zusätzliche Deformationsenergie aus dem Löngsstoß aufzunehmen und abzubauen.After absorption of the absorption capacity and the available deformation path of the energy dissipation element 1, the second stage 7 of the collision protection device responds. This second stage 7 is - as mentioned at the beginning of the description - designed to absorb and reduce additional deformation energy from the Löngstoß after exceeding a predetermined longitudinal force.

Da die Energieabsorptionselemente 1 fest mit dem Druckstück 5 verbunden sind, das seinerseits längsverschieblich gegenüber dem Wagenkasten 6 mit diesem über die zweite Stufe 7 verbunden ist, wird das Druckstück 5 nach Überschreiten der Ansprechkraft in Stoßrichtung längsverschoben. Dabei wird die zweite Stufe 7 beaufschlagt und weitere Stoßenergie abgebaut. Weil am Druckstück 5 auch die Einrichtungen für den Fahrzeugführer einschließlich Fahrzeugführersitz 8 als Baugruppe befestigt sind, werden diese zusammen mit dem Druckstück 5 nach hinten zum Wagenkasten 6 hin in den weniger gefährdeten Bereich zwangsverschoben, wobei die Einrichtungen des Führerstandes gegeneinander im wesentlichen beabstandet bleiben und sich nicht in einer den Fahrzeugführer gefährdende Weise verschieben. Insbesondere bleibt das Fahrerpult beabstandet zum Fahrzeugführersitz und verhindert so ein Einklemmen des Fahrzeugführers.Since the energy absorption elements 1 are fixedly connected to the pressure piece 5, which in turn is longitudinally displaceable relative to the car body 6 connected thereto via the second stage 7, the pressure piece 5 is longitudinally displaced after exceeding the Ansprechkraft in the shock direction. In this case, the second stage 7 is applied and reduced further impact energy. Because the pressure piece 5 and the facilities for the driver including driver's seat 8 are attached as an assembly, they are forcibly moved together with the pressure piece 5 back to the car body 6 in the less vulnerable area, the facilities of the cab remain substantially mutually spaced and do not move in a way that endangers the driver. In particular, the driver's console remains at a distance from the driver's seat and thus prevents jamming of the vehicle driver.
