Abstract

The energy dissipating device (3) has at least one energy dissipating element (5) and power input element (6) for the rail vehicle (1). This acts on the further impact and energy build-up after the energy receiving capacity of the primary reversible energy dissipating device has been used up. There is at least one energy dissipating element or its force input element fitted in the endface of the rail vehicle, within the vehicle outline. After the activation of one dissipating element (4) by an activation mechanism (7), the other element is pushed forward against the direction of impact outside the endface outline of the vehicle onto the corresponding element of the next vehicle.

Description

Die Erfindung betrifft eine Überstoß-Energieverzehreinrichtung für Schienenfahrzeuge nach dem Oberbegriff des Anspruchs 1.The invention relates to an impact energy absorption device for rail vehicles according to the preamble of claim 1.

Aus der DE 36 32 578 A1 ist eine gattungsgemäße Energieverzehreinrichtung bekannt, die einen horizontalen, im wesentlichen geraden Kupplungsquerträger aufweist, der längsverschieblich im Fahrzeug-Kopfstück angeordnet ist und der in der Fahrzeuglängsachse gelenkig die Mittelpufferkupplung mit der primär Energieverzehreinrichtung und seitlich nahe seinen Querenden die sekundäre Energieverzehreinrichtung trägt. Die primäre Energieverzehreinrichtung soll die beim Fahr- und Rangierbetrieb auftretenden Kräfte absorbieren, die sekundäre Energieverzehreinrichtung soll die aus überhöhten Auflaufstößen (Überstößen) resultierende Aufstoßenergie aufnehmen. Die sekundäre Energieverzehreinrichtung ist in Form von seitlich angeordneten, seitenpufferähnlichen Stoßelementen ausgebildet. Die Stoßelemente tragen stirnseitig Kletterschutzprofile.A generic energy consumption device is known from DE 36 32 578 A1, which has a horizontal, essentially straight coupling cross member, which is arranged in the vehicle head piece and which in the The vehicle's longitudinal axis articulates the center buffer coupling with the primary energy consumption device and laterally near its transverse ends, the secondary energy dissipation device wearing. The primary energy consumption device is intended for driving and Absorbing shunting forces occurring, the secondary energy dissipation device should be the belching energy resulting from excessive run-up impacts record, tape. The secondary energy consumption device is in the form of lateral arranged, side buffer-like shock elements. The push elements carry climbing protection profiles on the front.

Bei Auflaufstößen innerhalb der zulässigen Grenzen wird die gesamte Energie in der primären Energieverzehreinrichtung, die hier innerhalb einer Mittelpufferkupplung angeordnet ist, aufgenommen. Beim Überschreiten der zulässigen Auflaufgeschwindigkeit und damit beim Überschreiten eines vorgegebenen Stoßenergieniveaus treffen die Kletterschutzeinrichtungen der Stoßelemente auf ein Hindernis oder die Kletterschutzeinrichtung eines anderen Schienenfahrzeuges, wobei dann die sekundäre Energieverzehreinrichtung durch Zurückweichen des Stoßelementes in Tätigkeit gesetzt wird. Die überschüssige Aufstoßenergie wird dann innerhalb der sekundären Energieverzehreinrichtung in Reibungs- bzw. Verformungsarbeit umgesetzt. Mit dem Zurückweichen des Stoßelementes wird zwangsläufig die Verspannung des Kupplungsquerträgers mit den Konsolen des Schienenfahrzeuges gelöst. Der Kupplungsquerträger kann jetzt zusammen mit der Mittelpufferkupplung soweit zurückgedrückt werden, bis die Aufstoßenergie in der sekundären Energieverzehreinrichtung an den Konsolen vollständig in Reibungs- bzw. Verformungsarbeit umgesetzt ist.In the event of impact impacts within the permissible limits, the entire energy in the primary energy dissipation device, which is here within a central buffer coupling is arranged, added. When the permissible run-up speed is exceeded and thus when a predetermined impact energy level is exceeded the climbing protection devices of the impact elements hit an obstacle or the climbing protection device of another rail vehicle, where then the secondary energy dissipation device by retreating the shock element is put into action. The excess belching energy is then within the secondary energy dissipation device implemented in friction or deformation work. With the retraction of the shock element, the tension is inevitable of the coupling cross member with the brackets of the rail vehicle. The clutch cross member can now together with the center buffer clutch be pushed back until the belching energy in the secondary energy dissipation device on the brackets completely implemented in friction or deformation work is.

Der Erfindung liegt die Aufgabe zugrunde, eine Überstoß-Energieverzehreinrichung für Schienenfahrzeuge zu schaffen, die Überstöße auf die Stirnseite eines Schienenfahrzeuges abbaut und das Versagen der tragenden Fahrzeugstruktur verzögert oder verhindert.The invention has for its object a surge energy consumption device for rail vehicles to create the overruns on the front of a rail vehicle degrades and delays the failure of the load-bearing vehicle structure or prevented.

Die aus dem normalen Eisenbahnbetrieb auftretenden Stoßkräfte werden in einer primären Energieverzehreinrichtung 3 abgebaut. Dieser primären Energieverzehreinrichtung 3 ist eine sekundäre Energieverzehreinrichtung, nämlich eine Überstoß-Energieverzehreinrichtung 4, nachgeschaltet, die nach Erschöpfen der primären Energieverzehreinrichtung den weiteren Stoß- und Energieabbau bewirkt. Die Überstoß-Energieversehreinrichtung 4 weist mindestens ein Überstoß-Energieverzehrelement 5 und ein Krafteinleitungselement 6, z. B. eine pufferähnliche Stoßplatte, auf. Die Überstoß-Energieverzehreinrichtung 5 und dessen Krafteinleitungselement 6 ist vor dem Beaufschlagen innerhalb oder im wesentlichen innerhalb der Fahrzeugkontur angeordnet. Nach dem Auslösen der Überstoß-Energieverzehreinrichtung 4 über einen Auslösemechanismus 7 wird das Überstoß-Energieversehrelement 5 gegen die Stoßrichtung nach vorn außerhalb der stirnseitigen Fahrzeugkontur verschoben. Dabei gelangt das Überstoß-Energieverzehrelement 5 des ersten Schienenfahrzeuges 1 über das Krafteinleitungselement 6 (Stoßplatte) zur Anlage an ein gleichartiges Krafteinleitungselement 6 eines Überstoß-Energieverzehrelementes 5 des gekuppelten zweiten Schienenfahrzeuges 1. Bei Fortdauer der Relativbewegungen gegeneinander bewirken die Überstoß-Energieversehrelemente 5 beider Schienenfahrzeuge 1 den weiteren Stoß- und Energieabbau.In Fig. 1, two end regions of two rail vehicles 1 are shown, which over Middle buffer clutches 2 are coupled together.

The surge energy consuming device 5 and its force application element 6 is before loading arranged inside or essentially within the vehicle contour. After triggering the overrun energy dissipation device 4 via a trigger mechanism 7 becomes the push-over energy supply element 5 against the thrust direction moved forward outside the front contour of the vehicle. Here comes the impact energy consumption element 5 of the first rail vehicle 1 the force introduction element 6 (abutment plate) for contact with a similar one Force application element 6 of a surge energy consumption element 5 of the coupled second rail vehicle 1. If the relative movements continue against each other cause the push-over energy supply elements 5 of both rail vehicles 1 further shock and energy reduction.

Vorteilhaft sind die Überstoß-Energieverzehreinrichtungen 4 der Schienenfahrzeuge 1 symmetrisch zur Fahrzeuglängsachse angeordnet, was durch eine symmetrische Anordnung von Überstoß-Energievertehrelementen 5 zu beiden Seiten der Mittelpufferkupplung 2 erzeugt wird. Der Auslösemechanismus 7 für den Vorschub der Überstoß-Energieverzehrelementen 5 wird durch die Mittelpufferkupplung 2 angesteuert.The surge energy absorption devices 4 of the rail vehicles are advantageous 1 arranged symmetrically to the longitudinal axis of the vehicle, which is indicated by a symmetrical Arrangement of push-over energy elements 5 on both sides of the central buffer coupling 2 is generated.
