Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft eine elektrische Fahrzeugkupplung mit einer Kontaktbuchse zum Herstellen einer elektrischen Verbindung zwischen zwei Schienenfahrzeugen.The invention relates to an electrical vehicle coupling with a contact socket for establishing an electrical connection between two rail vehicles.

STAND DER TECHNIKSTATE OF THE ART

Um zwei Schienenfahrzeuge zu kuppeln, bedarf es einer mechanischen und einer elektrischen Kupplung. Die mechanische Kupplung überträgt die Zugkräfte des Triebfahrzeugs auf die übrigen Wagen und die elektrische Kupplung schafft den elektrischen Kontakt zu Steuerungs- und Versorgungszwecken.A mechanical and an electrical coupling are required to couple two rail vehicles. The mechanical coupling transmits the tractive force of the locomotive to the other vehicles and the electrical coupling creates the electrical contact for control and supply purposes.

Im Hinblick auf grössere Effizienz bezüglich Personal und Rollmaterial besteht das Verlangen nach einer vollautomatischen Fahrzeugkupplung.With regard to greater efficiency in terms of personnel and rolling stock, there is a demand for a fully automatic vehicle clutch.

Für eine vollautomatische elektrische Fahrzeugkupplung muss die Kontaktbuchse mit den elektrischen Kontakten vorgeschoben und zurückgezogen werden können. In der vorgeschobenen Stellung, d.h. in der gekuppelten Position, muss auch bei kleinen Verschiebungen z.B. aufgrund des Spiels der mechanischen Kupplung der elektrische Kontakt mit der Kontaktbuchse des angekuppelten Fahrzeugs gewährleistet sein. Ferner soll die Kupplung sowohl mechanisch als auch elektrisch einfach sein.For a fully automatic electrical vehicle coupling, it must be possible to advance and retract the contact socket with the electrical contacts. In the advanced position, i.e. in the coupled position, even with small displacements e.g. due to the play of the mechanical coupling, the electrical contact with the contact socket of the coupled vehicle can be ensured. Furthermore, the clutch should be both mechanically and electrically simple.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Aufgabe der Erfindung ist es daher, eine elektrische Fahrzeugkupplung mit einer Kontaktbuchse zum Herstellen einer elektrischen Verbindung zwischen zwei Schienenfahrzeugen anzugeben, welche vollautomatisch arbeitet, einfach und kompakt ist und sich im Notfall auch manuell betätigen lässt.The object of the invention is therefore to provide an electrical vehicle coupling with a contact socket for establishing an electrical connection between two rail vehicles, which operates fully automatically, is simple and compact and can also be operated manually in an emergency.

Erfindungsgemäss besteht die Lösung darin, dass ein stets gleichsinnig drehender Antrieb mittels eines Exzenters die Kontaktbuchse sowohl (zum Ankuppeln) vorschiebt als auch (zum Abkuppeln) zurückzieht.According to the invention, the solution is that a drive that always rotates in the same direction by means of an eccentric both pushes the contact socket (for coupling) and also pulls it back (for uncoupling).

Gemäss einer bevorzugten Ausführungsform umfasst der Exzenter ein Scheibenrad mit einem exzentrisch angebrachten Rollrad und eine Gleitschiene, in welcher das Rollrad geführt wird.According to a preferred embodiment, the eccentric comprises a disk wheel with an eccentrically mounted roller wheel and a slide rail in which the roller wheel is guided.

Bevorzugterweise ist die Kontaktbuchse am Ende einer Stossachse befestigt, auf welcher die Gleitschiene axial federnd gelagert ist, wobei die Gleitschiene senkrecht zur Stossachse steht. Der Exzenter hat dann eine Exzentrizität von (Δx  +  ε)/2, wobei Δx einen Sollvorschub und ε einen Kompressionsvorschub bezeichnen.The contact socket is preferably fastened at the end of an impact axis on which the slide rail is axially resiliently mounted, the slide rail being perpendicular to the impact axis. The eccentric then has an eccentricity of (Δx + ε) / 2, where Δx denotes a nominal feed and ε a compression feed.

Weitere bevorzugte Ausführungsformen ergeben sich aus den abhängigen Patentansprüchen.Further preferred embodiments result from the dependent patent claims.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Fig. 1 zeigt eine Explosionszeichnung einer bevorzugten Ausführungsform der Erfindung.Fig. 1 shows an exploded view of a preferred embodiment of the invention.

Ein Antrieb 1, z.B. ein elektrischer Motor, ist mit einer starken Untersetzung 1.2, z.B. einem Schneckengetriebe ausgerüstet. An einem Ausgang der Untersetzung 1.2 befindet sich ein Ritzel 1.3, welches in ein kuppelbares Zahnrad 2 eingreift. Dieses wiederum ist über eine erste Achse mit einem untersetzenden Zahnrad 4.2 verbunden. Das untersetzende Zahnrad 4.2 treibt ein Scheibenrad 4.1 an. Die beiden Zahnräder 2 und 4.2 bilden so ein Getriebe.A drive 1, e.g. an electric motor, has a strong reduction 1.2, e.g. equipped with a worm gear. At an output of the reduction 1.2 there is a pinion 1.3 which engages in a gear 2 which can be coupled. This in turn is connected to a step-down gear 4.2 via a first axis. The step-down gear 4.2 drives a disk wheel 4.1. The two gears 2 and 4.2 form a gear.

Das Scheibenrad 4.1 ist mit einem exzentrisch angebrachten Rollrad (in Fig. 1 nicht zu sehen) versehen, welches in einer Gleitschiene 5.1 läuft. Scheibenrad 4.1, Rollrad und Gleitschiene 5.1 bilden somit einen Exzenter.The disc wheel 4.1 is provided with an eccentrically mounted roller wheel (not shown in FIG. 1) which runs in a slide rail 5.1. Disc wheel 4.1, roller wheel and slide rail 5.1 thus form an eccentric.

Die Gleitschiene 5.1 ist auf einer Stossachse 5 gelagert. Dabei steht die Gleitschiene 5.1 senkrecht zur Stossachse 5 und ist in axialer Richtung auf der Stossachse verschiebbar. An einem vorderen Ende der Stossachse 5 ist schliesslich eine Kontaktbuchse 6 befestigt, welche den elektrischen Kontakt mit einem zweiten, angekuppelten Fahrzeug schafft.The slide rail 5.1 is mounted on an impact axis 5. The slide rail 5.1 is perpendicular to the joint axis 5 and can be moved in the axial direction on the shock axis. Finally, a contact socket 6 is attached to a front end of the shock axis 5, which creates electrical contact with a second, coupled vehicle.

Zwischen der Kontaktbuchse 6 und der Gleitschiene 5.1 ist eine Feder 5.2 angeordnet, welche die Stossachse 5 bezüglich der Gleitschiene 5.1 nach vorne drückt. Ein auf die Stossachse 5 aufgesetzter Bund (in Fig. 1 nicht sichtbar) bietet der Gleitschiene 5.1 gegen hinten einen Anschlag.A spring 5.2 is arranged between the contact socket 6 and the slide rail 5.1, which presses the shock axis 5 with respect to the slide rail 5.1. A collar placed on the impact axis 5 (not visible in FIG. 1) offers the slide rail 5.1 a stop against the rear.

Die Kontaktbuchse 6 weist an ihrer Vorderseite elektrische Kontakte 6.2 auf, welche über Kabel in einer Kabelführung 6.3 mit den entsprechenden Teilen im Fahrzeug verbunden sind. Ein klappbarer Schutzdeckel 6.1 deckt die elektrischen Kontakte ab, wenn keine elektrische Kupplung mit einem anderen Fahrzeug besteht.The contact socket 6 has on its front side electrical contacts 6.2, which are connected via cables in a cable guide 6.3 to the corresponding parts in the vehicle. A hinged protective cover 6.1 covers the electrical contacts when there is no electrical coupling with another vehicle.

Ein Kasten 3 nimmt den Exzenter und Teile des untersetzenden Getriebes auf.A box 3 receives the eccentric and parts of the reduction gear.

Anhand von Figuren 2 bis 4 wird im folgenden das Funktionsprinzip der elektrischen Fahrzeugkupplung erläutert. In allen Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen.The functional principle of the electrical vehicle clutch is explained below with reference to FIGS. 2 to 4. The same parts are provided with the same reference symbols in all the figures.

Fig. 2 zeigt eine Darstellung der Stossachse 5 in zurückgezogener Position. Von den bereits beschriebenen Teilen sind in Figuren 2 bis 4 folgende zu erkennen: Das Scheibenrad 4.1, das Rollrad 4.3, welches in die Gleitschiene 5.1 eingreift, die Feder 5.2, der auf die Stossachse 5 aufgesetzte Bund 5.3, die Kontaktbuchse 6 und der Schutzdeckel 6.1.Fig. 2 shows an illustration of the shock axis 5 in the retracted position. The following can be seen in FIGS. 2 to 4 of the parts already described: the disk wheel 4.1, the roller wheel 4.3, which engages in the slide rail 5.1, the spring 5.2, the collar 5.3 placed on the impact axis 5, the contact socket 6 and the protective cover 6.1 .

Das Scheibenrad 4.1 und die Gleitschiene 5.1 sind maximal zurückgezogen im hinteren toten Punkt des Scheibenrades 4.1. Der Schutzdeckel 6.1 ist heruntergeklappt.The disk wheel 4.1 and the slide rail 5.1 are retracted to the maximum at the rear dead point of the disk wheel 4.1. The protective cover 6.1 is folded down.

Zum Kuppeln wird das Scheibenrad 4.1 mittels des Antriebes 1 und des Getriebes z.B. in der eingezeichneten Richtung gedreht. Das Rollrad 4.3 und die Gleitschiene 5.1 verwandeln die drehende in eine lineare Bewegung. Die Stossachse 5 mit der Kontaktbuchse 6 wird vorgeschoben, und gleichzeitig wird der Schutzdeckel 6.1 hochgeklappt. Für diesen Zweck ist der Schutzdeckel 6.1 z.B. an der Kontaktbuchse 6 um eine senkrecht zur Zeichenebene stehende Achse drehbar befestigt und durch eine Stange mit dem sich nicht bewegenden Kasten 3 verbunden.For coupling the disc wheel 4.1 by means of the drive 1 and the gearbox rotated, for example, in the direction shown. The roller wheel 4.3 and the slide rail 5.1 convert the rotating into a linear movement. The impact axis 5 with the contact socket 6 is advanced, and at the same time the protective cover 6.1 is folded up. For this purpose, the protective cover 6.1 is fastened, for example, to the contact socket 6 so as to be rotatable about an axis perpendicular to the plane of the drawing and connected to the non-moving box 3 by a rod.

Fig. 3 zeigt eine Darstellung der Stossachse 5 in vorgeschobener Position. Die Stossachse 5 ist nun um einen Sollvorschub Δx vorgeschoben, die Kontaktbuchse 6a berührt nun die symmetrisch vorgeschobene Kontaktbuchse 6b des anzukuppelnden, zweiten Fahrzeugs. Das Scheibenrad 4.1 hat sich allerdings noch nicht um volle 180° gegenüber der Ausgangslage von Fig. 2 gedreht.Fig. 3 shows an illustration of the shock axis 5 in the advanced position. The shock axis 5 is now advanced by a desired feed rate .DELTA.x, the contact socket 6a now touches the symmetrically advanced contact socket 6b of the second vehicle to be coupled. However, the disk wheel 4.1 has not yet rotated a full 180 ° with respect to the starting position in FIG. 2.

Fig. 4 zeigt schliesslich die Stossachse 5, wenn das Scheibenrad 4.1 um volle 180° gegenüber der Ausgangslage gedreht ist und damit im vorderen toten Punkt ist. Die Gleitschiene 5.1 ist um einen Kompressionsvorschub ε weiter vorgeschoben auf die Stossachse 5, wodurch die Feder 5.2 gespannt worden ist. Die beiden Kontaktbuchsen 6a, 6b der gekuppelten beiden Fahrzeuge werden aneinander gepresst.4 finally shows the impact axis 5 when the disk wheel 4.1 is rotated through a full 180 ° with respect to the starting position and is thus in the front dead point. The slide rail 5.1 is advanced by a compression feed ε onto the shock axis 5, whereby the spring 5.2 has been tensioned. The two contact sockets 6a, 6b of the coupled two vehicles are pressed together.

Wenn aus irgendeinem Grund (z.B. wegen Panne oder Leerversuch) die Kontaktbuchse 6b des anderen Fahrzeugs nicht da ist, um Gegendruck zu bieten, dann wird die Stossachse natürlich um ein Wegstück von insgesamt Δx  +  ε vorgeschoben und die Feder 5.2 wird nicht gespannt.If for some reason (e.g. due to a breakdown or empty test) the contact socket 6b of the other vehicle is not there to offer counter pressure, then the shock axis is of course advanced by a total distance of Δx + ε and the spring 5.2 is not tensioned.

Zum Abkuppeln wird das Scheibenrad 4.1 mittels Antrieb 1 und Getriebe im gleichen Drehsinn um 180° weitergedreht, so dass es wieder in die in Fig. 2 gezeigte Stellung kommt. Dabei wird, in Umkehrung zum Ankoppeln, die Gleitschiene 5.1 um eine Strecke Δx  +  ε und die Stossachse um eine Strecke Δx zurückgezogen.For uncoupling, the disk wheel 4.1 is rotated further in the same direction by 180 ° by means of drive 1 and gear, so that it comes back into the position shown in FIG. 2. In reverse to coupling, the slide rail 5.1 is withdrawn by a distance Δx + ε and the shock axis by a distance Δx.

Es ist ein Vorteil der Erfindung, dass der Antrieb zyklisch und kontinuierlich arbeiten kann. Das Scheibenrad 4.1 bewirkt mit einer Umdrehung die beiden Funktionen "Ankuppeln" und "Abkuppeln".It is an advantage of the invention that the drive can work cyclically and continuously. The disc wheel 4.1 effects the two functions “coupling” and “uncoupling” with one revolution.

Bei einer bevorzugten Ausführungsform ist es möglich, das Zahnrad 4.2 auszurücken und so den kraftschlüssigen Kontakt zwischen Antrieb 1 und Scheibenrad 4.1 zu lösen. Gleichzeitig kann an einer Achse des Scheibenrades 4.1 ein Hebel befestigt werden, um dieses von hand direkt zu drehen. Auf diese Weise ist es möglich, die Kupplung auch dann zu betätigen, wenn der Antrieb 1 defekt ist.In a preferred embodiment, it is possible to disengage the gear 4.2 and thus to release the non-positive contact between the drive 1 and the disk gear 4.1. At the same time, a lever can be attached to an axis of the disk wheel 4.1 in order to turn it directly by hand. In this way it is possible to actuate the clutch even if the drive 1 is defective.

Gemäss einer weiteren bevorzugten Ausführungsform kann vom Ritzel 1.3 (Fig. 1) mittels eines kuppelbares Scheibenrades 7.1 eine Nockenwelle 7 angekuppelt werden, mit welcher ein Entriegelungsmechanismus einer in Fig. 1 nicht gezeigten mechanischen Kupplung betätigt werden kann.According to a further preferred embodiment, the pinion 1.3 (FIG. 1) can be coupled to a camshaft 7 by means of a clutchable disk wheel 7.1, with which a release mechanism of a mechanical clutch, not shown in FIG. 1, can be actuated.

Das kuppelbare Zahnrad 2 muss dazu vom Ritzel 1.3 abgekoppelt und das Scheibenrad 7.1 angekoppelt werden. Mit dem Antrieb 1 wird dann die Nockenwelle 7 einmal gedreht. Danach wird das kuppelbare Zahnrad 2 wieder an das Ritzel 1.3 an- und das Scheibenrad 7.1 abgekoppelt.The detachable gear 2 must be decoupled from the pinion 1.3 and the disc wheel 7.1 coupled. With the drive 1, the camshaft 7 is then rotated once. Thereafter, the detachable gear 2 is again connected to the pinion 1.3 and the disk wheel 7.1 is uncoupled.

Insgesamt schafft die Erfindung eine elektrische Fahrzeugkupplung, welche vollautomatisch arbeitet, einen guten elektrischen Kontakt auch bei Erschütterungen sichert und mechanisch und elektrisch einfach ist.Overall, the invention provides an electrical vehicle clutch that operates fully automatically, ensures good electrical contact even when shaken, and is mechanically and electrically simple.
