This is e.g. a tube, which is deformed by a nozzle (25) or a pressure ring (21), after a set pressure and/or traction load limit on shear ring (20) and/or pin has been exceeded.

Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Zug- und Stoßvorrichtung mit einem Kupplungsarm für Mittelpufferkupplungen von Schienenfahrzeugen, die im Untergestell eines Schienenfahrzeuges angeflanscht befestigt ist und den Kupplungsarm mit einem Kupplungskopf über ein Gelenk, vorzugsweise Stabilisierungsgelenk, das an einem Gelenkbolzen angelenkt ist, elastisch gelagert und in Druckrichtung die Druckkräfte nach Überschreiten einer Gelenkspielabfederung spielfrei über eine Druckplatte und ein nachgeschaltetes vorgespanntes, druckseitiges Energieverzehrsystem auf das Untergestell über ein äußeres Gehäuse abstützt sowie in Zugrichtung die Zugkräfte über den Gelenkbolzen und ein zugseitiges Energieverzehrsystem spielfrei über Zuganschläge und das äußere Gehäuse auf das Untergestell abstützt.The invention relates to a pulling and pushing device with a coupling arm for central buffer clutches of rail vehicles, which is mounted flanged in the base of a rail vehicle and the coupling arm with a coupling head via a joint, preferably stabilizing joint, which is hinged to a hinge pin, elastically mounted and in the compression direction Pressure forces after exceeding a Gelenkspielabfederung backlash over a pressure plate and a downstream biased, pressure-side energy dissipation system supported on the frame via an outer housing and in the pulling direction the tensile forces on the hinge pin and a zugseitiges energy dissipation system without play on cable stops and the outer housing is supported on the undercarriage.

Stand der TechnikState of the art

Eine solche Vorrichtung ist beispielsweise aus der EP 1 225 114 B1 bekannt.Such a device is for example from the EP 1 225 114 B1 known.

Es sind Zug- und Stoßvorrichtungen bekannt , z.B. nach DE 1 455 255 A , mit geschlossenem Gehäuse und Zugbügel, bei denen der Kupplungsarm eine Mittelpufferkupplung im Zugbügel gelagert ist.There are train and push devices known, for example DE 1 455 255 A , with closed housing and drawbar, in which the coupling arm is mounted a central buffer coupling in the drawbar.

Das zwischen den fahrzeugseitigen Anschlägen vorgespannte Federsystem führt toleranzbedingt zum Spiel des Zugbügels bei Zugbelastung und Rucken und Zerrungen bei Fahrt im Zugverband. Das geschlossene Federgehäuse mit der eingesetzten Ringfeder ist aufwendig.The preloaded between the vehicle-side stops spring system causes tolerances due to the game of the drawbar in tensile load and jerking and strains when driving in the train. The closed spring housing with the ring spring used is expensive.

Weiterhin sind Zug- und Stoßvorrichtungen nach DD-PS 82 681 bekannt, deren ineinander geschaltete Vorhub- und Hauptfeder über Vorspanntöpfe und Zuganker aufwendig im geschlossenen Gehäuse gelagert sind. Bei vorgespanntem Einbau in die fahrzeugseitigen Anschläge tritt auch hier Spiel zwischen Gelenkbolzen und Gehäuse auf, das zu den unerwünschten Rucken und Zerrungen bei Fahrt im Zugverband führt. Stabilisierungsgelenke werden in ihrer Stabilisierungswirkung durch die sphärische Lagerung am Gelenkbolzen abgemindert. Es sind ebenfolls zug- und stoßvorichtungen bekannt, die ein irreversibles stoßverzehrglied aufweisen, wie z.B. in der EP-A-D417594 .Furthermore, pull and push devices are after DD-PS 82 681 known, the inter-connected Vorhub- and main spring over preload pegs and tie rods are stored consuming in a closed housing. With biased installation in the vehicle-side stops occurs here game between hinge pin and housing, which leads to the unwanted jerking and strains when driving in the train. Stabilizing joints are reduced in their stabilizing effect by the spherical bearing on the hinge pin. There are ebenfolls zug- and shock devices known that have an irreversible shock-absorbing member, such as in the EP-A-D417594 ,

Darstellung der Erfindung, Aufgabe, Lösung, VorteilePresentation of the invention, object, solution, advantages

Die Aufgabe der Erfindung besteht darin, eine anflanschbare Zug- und Stoßvorrichtung mit hohem Energieverzehrsystem zum bestmöglichen Schutz im Crashfall mit nichtliniarer Kennlinie des Federsystems zur Dämpfung der Längsschwingungen während der Fahrt und spielfreier Lagerung der Kupplungsarmanbringung zur Abminderung der Rucke und Zerrungen bei Fahrt zu schaffen.The object of the invention is to provide a flanged pull and push device with high energy dissipation system for the best possible protection in the event of a crash with non-linear characteristic of the spring system for damping the longitudinal vibrations while driving and play-free storage of Kupplungsarmanbringung to reduce the jerks and strains while driving.

Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.According to the invention the object is achieved by a device having the features of claim 1. Advantageous embodiments are specified in the subclaims.

Die Kernidee der Erfindung besteht darin, dass die bisher an sich schon bekannten Energieverzehrsysteme, nämlich ein Energieverzehrsystem für eine zugseitige Belastung und ein mehrstufiges Energieverzehrsystem für eine druckseitige Belastung, von denen bisher mindestens eines außerhalb des Gehäuses des Mittelpufferfederwerks angeordnet war, beide im Gehäuse angeordnet sind, und zwar in einer Reihenschaltung.The core idea of the invention is that the previously known per se energy absorption systems, namely an energy dissipation system for a zugseitige load and a multi-stage energy dissipation system for a pressure-side load, of which at least one was arranged outside the housing of the central buffer spring mechanism, both are arranged in the housing , in a series connection.

Damit ist sichergestellt, dass größere Absorptionsenergien über das entsprechende Energieverzehrsystem abgefedert und aufgefangen werden, so dass Schäden bei Aufläufen der Schienenfahrzeuge mit unzulässigen höheren Geschwindigkeiten sich nicht auf die Fahrzeugstruktur auswirken und auf den leicht tauschbaren Teil der Zug- und Stoßvorrichtung begrenzt bleiben und eine Abminderung der Rucke und Zerrungen bei Fahrt erreicht wird und dass auch eine Dämpfung der Längsschwingungen während der Fahrt erzielt wird.This ensures that larger absorption energies are cushioned and absorbed via the corresponding energy dissipation system, so that damage to crawlers of the rail vehicles with impermissibly higher speeds does not affect the vehicle structure and remain limited to the easily replaceable part of the pulling and pushing device and a reduction the jerks and strains while driving is achieved and that also a damping of the longitudinal vibrations is achieved while driving.

Besweiteren ist vorgesehen, dass das druckseitige mehrstufige Energieverzehrsystem und/oder das zugseitige Energieverzehrsystem mit einem reversiblen Energieabsorptionsteil und einem irreversibel verformbaren Verformungselement versehen sind. Hierdurch ist es erreichbar, dass auch größere Energien, die beispielsweise bei einem Crashfall auftreten, aufgenommen werden und so Beschleunigungsspitzen in Bezug auf das Schienenfahrzeug bzw. in Bezug auf seine Ladung oder die beförderten Personen vermieden werden.It is further provided that the pressure-side multistage energy dissipation system and / or the train-side energy dissipation system are provided with a reversible energy absorption part and an irreversibly deformable deformation element. This makes it possible to absorb even larger energies, which occur, for example, in the event of a crash, thus avoiding acceleration peaks with respect to the rail vehicle or with respect to its load or the passengers being transported.

Der Einbau in einem Gehäuse für den reversiblen Energieverzehr und dem irreversiblen Energieverzehr hat den Vorteil, dass einerseits die normalen Belastungen im Rangierbetrieb und Zugverbandsbetrieb über den reversiblen Energieverzehr aufgenommen werden und dass andererseits im Crashfall die Zug- und Stoßvorrichtung wesentlich höhere zusätzliche Energie im irreversiblen Energieverzehr aufnimmt. Im Bereich der Fahrzeugstruktur sind keine hinter oder neben der Zug- und Stoßvorrichtung angeordneten zusätzlichen Crashelemente für den nach den europäischen Crashbedingungen geforderten Aufprall eines Zugverbandes mit 36 km/h Aufprallgeschwindigkeit erforderlich.The installation in a housing for the reversible energy consumption and the irreversible energy consumption has the advantage that on the one hand the normal loads in maneuvering and Zugverband operation are absorbed by the reversible energy consumption and on the other hand, in the event of a crash absorbs the traction and shock device much higher additional energy in the irreversible energy consumption , In the area of the vehicle structure, no additional crash elements arranged behind or next to the pulling and pushing device are required for the impact of a train with a speed of 36 km / h which is required according to the European crash conditions.

Weiterhin von Vorteil ist die Ausbildung des Verformungselementes mit den vorgespannten Abscherelemente, so dass kein Lockern der Verbindung eintritt und unerwünschte Spiele vermieden werden.Another advantage is the formation of the deformation element with the prestressed shear elements, so that no loosening of the compound occurs and unwanted games are avoided.

Unterschiedliche Gelenkausführungen der Mittelpufferkupplungen werden über die Anpassung der Druckplatte ohne Änderung des weiteren Innenlebens der Zug- und Stoßvorrichtung vorteilhaft eingebaut.Different joint designs of the central buffer couplings are advantageously installed on the adaptation of the pressure plate without changing the further inner life of the pull and push device.

Die Gelenkbolzenlagerung in der Haube setzt die sichere Lagerung des Gelenkbolzens spielarm um, wobei vorteilhaft einerseits ein Herausfallen des Gelenkbolzens verhindert ist und andererseits beim Ein- und Ausbau der Kupplung oder des Zughakens die Zug- und Stoßvorrichtung mit dem Untergestell des Fahrzeugs verschraubt bleibt. Die nichtlineare Kennlinie der Feder des Energieverzehrsystems dämpft vorteilhaft die Längsschwingungen bei Fahrt im Zugverband.The hinge pin bearing in the hood is the safe storage of the hinge pin low-clearance, which advantageously on the one hand a falling out of the hinge pin is prevented and on the other hand when installing and removing the clutch or the tow hook the pull and push device remains bolted to the undercarriage of the vehicle. The non-linear characteristic of the spring of the energy dissipation system advantageously dampens the longitudinal vibrations when traveling in a train.

Das im von außen sichtbaren Bereich der Zug- und Stoßvorrichtung angebrachte Abscherelement schert beim Ansprechen des irreversiblen Energieverzehrs ab und zeigt vorteilhaft die stattgefundene hohe Belastung an.The shearing element mounted in the externally visible region of the pulling and pushing device shears off when the irreversible consumption of energy occurs, and advantageously indicates the high load that has taken place.
