Abstract
Description
Die Erfindung betrifft einen Stromabnehmer für ein Fahrzeug, insbesondere ein Eisenbahn- oder ein Straßenbahnfahrzeug, gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a pantograph for a vehicle, in particular a railway or tram vehicle, according to the preamble of Claim 1.
Stromabnehmer für Straßenbahnen sowie Eisenbahnen sind auch für vergleichsweise niedrige Versorgungsspannungen (z.B. 700 V) bekannt. Diese weisen eine Schleifleiste auf, welche gegen einen als Fahrdraht ausgebildeten Stromleiter gedrückt wird, so dass über den auf diese Weise hergestellten Kontakt eine Stromentnahme ermöglicht wird. Die Schleifleisten erfahren im Bereich des Kontakts eine Erwärmung, die während der Fahrt dadurch über die Länge der Schleifleisten verteilt wird, dass der Fahrdraht zick-zack-förmig verläuft. Auf diese Weise wird erreicht, dass der Kontakt ständig über die Länge der Schleifleisten wandert.pantograph for trams as well as railways are also for comparatively low supply voltages (e.g., 700V) are known. These have an abrasive strip, which against a contact wire trained conductor is pressed so that over the current produced in this way a current drain is made possible. The contact strips experience a heating in the area of the contact, the while drive over it the length the contact strip is distributed so that the contact wire runs zig-zag. On in this way it is achieved that the contact constantly moves over the length of the grinding bars.
Problematisch ist der Fall, wenn die Bahn bei niedrigen Versorgungsspannungen längere Zeit anhalten und dabei ein größerer Strom entnehmbar sein muss, beispielsweise weil die Klimaanlage in Betrieb ist, da der zulässige Oberstrom bei einem Halt nur etwa 13 % des Stroms beträgt, der beim Fahren entnehmbar ist.Problematic is the case when the web is at low supply voltages longer Stop time and get a bigger current must be removable, for example, because the air conditioning in operation is because the allowed Upper flow at a stop is only about 13% of the electricity, the can be removed while driving.
Aus diesem Grunde werden im städtischen Bereich, insbesondere bei niedrigen Versorgungsspannungen, beispielsweise nur kurze Bahnen eingesetzt, welche die kritische Klimaleistung im o.g. Fall nicht erreichen.Out that's why in the urban area, especially at low supply voltages, for example only short tracks used, which the critical climatic achievement in the o.g. Do not reach the case.
Eine andere Lösung sieht vor, dass weitere Stromabnehmer vorgesehen sind, welche nur bei stehendem Zug aktiviert, also angehoben werden.A another solution provides that additional pantographs are provided, which only activated when the train is stationary, that is raised.
Die Aufgabe der Erfindung ist es, einen Stromabnehmer zu schaffen, der auch bei stehendem Fahrzeug eine hohe Stromentnahme über einen Stromleiter ermöglicht.The The object of the invention is to provide a current collector, the even when the vehicle is a high current drain over a conductor allows.
Die Aufgabe der Erfindung wird durch die Merkmale des Anspruchs 1 gelöst; die Unteransprüche beschreiben vorteilhafte Ausgestaltungen.The The object of the invention is solved by the features of claim 1; the under claims describe advantageous embodiments.
Die Lösung sieht vor, dass zur Verteilung der Erwärmung bei stehendem Fahrzeug eine Bewegung des Kontaktpunktes entlang des Stromleiters und/oder entlang der Kontaktfläche vorgesehen ist. Die Bewegung des Kontaktpunktes sorgt auf einfache Art und Weise dafür, dass eine Verteilung der Erwärmung stattfindet, so dass auch bei stehendem Fahrzeug ein entsprechend hoher Strom über den Stromleiter entnehmbar ist.The solution provides that to distribute the warming when the vehicle is stationary a movement of the contact point along the conductor and / or along the contact surface is provided. The movement of the contact point ensures easy Way for it, that a distribution of warming takes place, so that even when the vehicle is a corresponding high current over the conductor is removable.
Am besten erfolgt die Bewegung des Kontaktpunktes als Relativbewegung zwischen der Kontaktfläche und dem Stromleiter so, dass sich die Erwärmung über die Kontaktfläche und den im Bewegungsbereich der Kontaktfläche liegenden Stromleiter verteilt.At the best is the movement of the contact point as a relative movement between the contact surface and the conductor so that the heating over the contact surface and the distributed in the range of movement of the contact surface conductor distributed.
Bei einer einfachen und zweckmäßigen Ausführung ist der Stromleiter als Fahrdraht ausgebildet.at a simple and expedient execution the conductor designed as a contact wire.
Zweckmäßigerweise ist die Kontaktfläche an einer Schleifleiste ausgebildet.Conveniently, is the contact surface formed on a grinding bar.
Die Schleifleiste ist zweckmäßigerweise an einem absenkbaren Arm des Stromabnehmers ausgebildet.The Sanding strip is expediently formed on a lowerable arm of the pantograph.
Die Erwärmung ist geringer, wenn der Stromabnehmer eine Bewegung ausführt und dabei der absenkbare Arm schräg zur Fahrtrichtung auf dem Dach des Fahrzeugs angeordnet ist.The warming is lower when the pantograph performs a movement and while the lowerable arm slanted is arranged to the direction of travel on the roof of the vehicle.
Eine technisch einfache Lösung sieht vor, dass die Bewegung der Schleifleiste gegenüber dem Fahrdraht mittels eines dafür ausgestalteten Widerlagers des absenkbaren Arms erfolgt.A technically simple solution Foresees that the movement of the sliding strip opposite the contact wire by means of it designed abutment of the lowerable arm takes place.
Alternativ kann die Bewegung der Schleifleiste auch mittels einer bewegbaren Wippe erfolgen.alternative The movement of the sanding bar can also be done by means of a movable Rocker made.
Die Dimensionierung des Stromabnehmers ist so ausgelegt, dass die Stromabnahme bei stehendem Fahrzeug zur Versorgung von Nichtantriebseinrichtungen, insbesondere einer Klimaanlage, erfolgt.The Sizing of the pantograph is designed so that the current decrease when the vehicle is stationary to supply non-drive equipment, in particular an air conditioner, takes place.
