Abstract
Description
Die Erfindung betrifft einen Stromabnehmer für ein elektrisches
Oberleitungsfahrzeug, insbesondere einen Oberleitungsbus, mit den
Merkmalen aus dem Oberbegriff des Schutzanspruchs 1. Derartige Stromabnehmer
sind an sich bekannt und beispielsweise in
Bei bekannten Stromabnehmern sind unterschiedliche Möglichkeiten der Hochstromübertragung vom Stromabnehmerkopf zum Fahrzeug bekannt.Known pantographs are different possibilities the high current transmission known from the pantograph head to the vehicle.
So ist es beispielsweise bei Stromabnehmern, bei welchen ein Kabel durch die Stromabnehmerstange geführt ist, bekannt, das Kabel am Ende der Stromabnehmerstange nach außen zu führen und direkt mit dem Stromabnehmerkopf zu verschrauben. Ein Nachteil dieser Lösung besteht darin, dass ein Austauschen des Stromabnehmerkopfes aufwendig ist. Weiterhin werden außenliegende Teile des Kabels bei Entgleisungen oft beschädigt und müssen dann mit viel Aufwand komplett erneuert werden.For example, with pantographs, where a cable is led through the pantograph rod, known to lead the cable to the outside at the end of the pantograph rod and to screw directly to the pantograph head. One disadvantage of this solution consists in the fact that replacing the pantograph head is expensive is. Furthermore, outside Parts of the cable are often damaged in the event of derailment and then have to be done with a lot of effort be completely renewed.
Es ist weiterhin bekannt, die Stromübertragung über eine Pressverbindung des Stromabnehmerkopfes mit dem Stangenende der Stromabnehmerstange zu bewirken. Dieses Prinzip der Stromübertragung kann sowohl bei stromführenden Stromabnehmerstangen als auch bei isolierten Stromabnehmerstangen eingesetzt werden, bei welchen ein innerhalb der Stromabnehmerstange geführtes Kabel mit einem zur Stromabnehmerstange hin isolierenden Endstück verbunden ist. Der Nachteil dieser Lösung besteht darin, dass der Presssitz zwischen dem Stangenende und dem Stromabnehmerkopf nicht zu einer flächigen Verbindung sondern nur zu lokal begrenzten Stromübergangspunkten führt. In der Praxis ergibt sich daher, insbesondere bei größeren Strömen, wie sie bei modernen Trolleybussen auftreten, oft ein Verschweißen des Stromabnehmerkopfes mit dem Stangenende der Stromabnehmerstange, was wiederum den Austausch des Stromabnehmerkopfes außerordentlich erschwert.It is also known to transmit electricity via a Press connection of the pantograph head to the rod end of the To cause pantograph rod. This principle of power transmission can be used in both live Current collector rods as well as insulated current collector rods be used in which a within the pantograph rod run Cable connected to an end piece that isolates from the current collector rod is. The disadvantage of this solution is that the press fit between the rod end and the Pantograph head not to a flat connection but only to locally limited power transition points leads. In practice, therefore, especially with larger currents, such as they occur on modern trolleybuses, often welding the Pantograph head with the rod end of the pantograph rod, which in turn makes the replacement of the pantograph head extraordinary difficult.
Der Erfindung liegt die Aufgabe zugrunde, einen Stromabnehmer mit den Merkmalen aus dem Oberbegriff des Schutzanspruchs 1 so auszugestalten, dass eine wartungsfreundliche mechanische Verbindung zwischen Stromabnehmerkopf und Stromabnehmerstange möglich ist, bei der gleichzeitig eine sichere Hochstromübertragung dauerhaft sichergestellt ist.The invention is based on the object a pantograph with the features from the preamble of the protection claim 1 to be designed so that a maintenance-friendly mechanical connection between pantograph head and pantograph rod is possible, which at the same time ensures a secure high-current transmission is.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Schutzanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This task is solved according to the invention with the Features from the characterizing part of the protection claim 1. Advantageous Further developments of the invention are described in the dependent claims.
Ein Grundgedanke der Erfindung besteht darin, dass die elektrische Verbindung zwischen dem Stromabnehmerkopf und den stromführenden Teilen der Stromabnehmerstange über einen Hochstromsteckverbinder erfolgt, der in die mechanische Verbindung zwischen dem Stromabnehmerkopf und dem Stangenende der Stromabnehmerstange integriert ist. Hierzu ist an dem dem Stromabnehmerkopf zugewandten Ende der Stromabnehmerstange ein Hochstromstiftkontakt angeordnet, der mit einem am Stromabnehmerkopf angeordneten Hochstrombuchsenkontakt zusammenwirkt. Die Verwendung eines derartigen, an sich bekannten, Hochstromsteckverbinders an dieser Stelle hat den Vorteil, dass dort eine lösbare elektrische Verbindung hergestellt wird, die andererseits eine gasdichte Verbindung an den Stromübergangsstellen ohne gasgefüllte Zwischenräume sicherstellt und einen korrekten axialen Sitz des Steckkontaktes gewährleistet. Somit ist einerseits eine dauerhaft sicherere Hochstromübertragung möglich und andererseits die Montage und Demontage des Stromabnehmerkopfes jederzeit ohne größeren Aufwand möglich, da keine Verschweißungen mehr auftreten können. Bei der Verwendung isolierender Stromabnehmerstangen ist auch keine außenliegende Kabelführung mehr notwendig, und daher können keine Kabelbeschädigungen bei Entgleisungen auftreten.A basic idea of the invention is in that the electrical connection between the pantograph head and the live one Share the pantograph rod over A high-current connector is used, which is in the mechanical connection between the pantograph head and the rod end of the pantograph rod is integrated. For this purpose, the head facing the pantograph A high current pin contact is arranged at the end of the current collector rod, the one with a high current socket contact arranged on the pantograph head interacts. The use of such a known, High current connector at this point has the advantage that there a detachable electrical connection is established, which on the other hand is gas-tight Connection at the power transfer points without gas-filled interspaces ensures and a correct axial fit of the plug contact guaranteed. Thus, on the one hand, there is a permanently safer high-current transmission possible and on the other hand the assembly and disassembly of the pantograph head at any time without much effort possible, there are no welds can occur more. When using insulating pantograph rods there is also none external cable management more necessary and therefore can no cable damage occur in derailments.
Es sind auch Ausführungsformen möglich, bei denen der Hochstromstiftkontakt am Stromabnehmerkopf und der Hochstrombuchsenkontakt an der Stromabnehmerstange angeordnet ist.Embodiments are also possible which the high current pin contact on the pantograph head and the high current socket contact is arranged on the pantograph rod.
Im folgenden werden anhand der beigefügten Zeichnungen zwei Ausführungsbeispiele für einen Stromabnehmer nach der Erfindung näher erläutert.The following are based on the attached drawings two embodiments for one Pantograph according to the invention explained in more detail.
