Description

Bügelstromabnehmer für elektrisch betriebene Fahrzeuge mit kleiner Schleifbügelmasse Es isst bekannt, die Schleifstückträger von Stromal)nehmern so auszubilden, daß ein federndes Ausweichen des Schleifstückes in Fahrtrichtung wie auch quer zur Fahrtrichtung möglich ist, so daß Höhenunterschiede an der Fahrdrahtlage aufgenommen werden können und beim Abgleiten des Fahrdrahtes vom Schleifbügel erster durch seitliches Ausweichen an dem nunmehr schräg gestellten Bügelarm wieder hochgleiten kann. Der Anpreßdruck und die Rückstellkräfte für den Schleifstückträger werden in üblicher Weise durch eine Anzahl Schraubenfedern, vorwiegend Druck- und Dehnungsfedern, erzeugt. Diese Federn beeinflussen infolge ihres hohen Eigengewichtes die Beweglichkeit dies Schleifstückbügels, so daß dieser nicht in der gewünschten Weise den Fahrdrahtunebenheiten folgt und damit zu Unregelmäßigkeiten in der Stromahnahme beiträgt. Weiter sind für die Beweglichkeit der Bügel eine Anzahl Gelenke erforderlich. die sich im Betrieb ungünstig auswirken.U-shaped pantographs for electrically operated vehicles with small Grinding hanger compound It is well known that Stromal) collectors are like this train that a resilient evasion of the contact strip in the direction of travel like is also possible transversely to the direction of travel, so that height differences at the contact wire position can be recorded and when the contact wire slides off the grinding hanger first slide up again by moving sideways on the now inclined bracket arm can. The contact pressure and the restoring forces for the contact strip carrier are in the usual way by a number of helical springs, mainly compression and expansion springs, generated. Due to their high weight, these springs influence mobility this contact strip bracket, so that it does not bump the contact wire in the desired manner follows and thus contributes to irregularities in the current intake. Are further a number of joints are required for the mobility of the stirrups. which are in operation have an unfavorable effect.

Um die Schleifbügelmasse, die Anzahl der Gelenke und anderer Bauelemente zu verkleinern und die Betriebseigenschaften zu verbessern, gelangt erfindungsgemäß) ein Bügelstromabnehmer für elektrisch betriebene Fahrzeuge zur Anwendung, in dessen Schleifbügelarme je ein federndes Glied eingebaut ist. «-elches den Schleifbügelarmen eine allseitige Bewegungsmöglichkeit erteilt. Damit das federnde Glied gleichzeitig als Isolator dienen kann, ist es vorteilhaft, als Gummi-Metall-Verbundkörper auszuführen.About the size of the grinding hanger, the number of joints and other components to reduce the size and improve the operating properties, according to the invention) a hoop pantograph for electrically powered vehicles for use in Sanding hanger arms each have a resilient link installed. «-Which the grinding hanger arms granted all-round movement. So that the resilient link at the same time can serve as an insulator, it is advantageous to design as a rubber-metal composite body.

Die nähere Erläuterung der Erfindung geschieht an Hand des in den Fig. 1 und 2 dargestellten Ausführungsbeispiels.The invention is explained in more detail using the in the Fig. 1 and 2 illustrated embodiment.

Zwei Unterarme 7 eines Bügelstromabnehmers sind in ihrem oberen Teil durch eine drehbar gelagerte Welle 9 miteinander verbunden. Welle 9 gewährleistet eine gleichsinnige Bewegung der Unterarme 7 und dient in Verbindung mit Führungsstange 8 zur Gradführung des Schleifbügelsystems. De Schleifbügelarme 1 sind mit ihren mit Welle 9 fest verbundenen Lagerteilen 3 über ein federndes Glied 2, beispielsweise über einen Gummi-Metall-Verbundkörper, verbunden. Um ein Verwinden der Schleifbügelarmne 1 zu verhindern, sind dieselben durch einen besonderen Schleifstückträger 5 über Gelenke 4 miteinander verbunden, welche ein Verdrehen der Schleifbügelarme 1 zum Schleifbügelträger nur in gleicher Ebene gestatten. Somit kann das im Schleifstückträger 5 um seine Längsachse drehbar aufgehängte Schleifstück 6 wohl in Fahrtrichtung und quer zur Fahrtrichtung aus-@t-eiche.n, sich jedoch nicht schräg unter Verlassen der horizontalen Lage und unter Nachschleppen einer Seite einstellen. Damit erfüllt der Bügelstromabnehmer alle an ihn gestellten Aufgaben mit erheblich verbesserten Betriebseigenschaften, geringen Bauelementen, einfacher Konstruktion und Wartung.Two forearms 7 of a hoop pantograph are in its upper part connected to one another by a rotatably mounted shaft 9. Wave 9 guaranteed a movement of the forearms 7 in the same direction and is used in conjunction with the guide rod 8 for guiding the angle of the grinding hanger system. De grinding hanger arms 1 are with their with shaft 9 firmly connected bearing parts 3 via a resilient member 2, for example connected via a rubber-metal composite body. About twisting the grinding hanger arm 1, the same are to be prevented by a special contact strip carrier 5 over Joints 4 connected to each other, which a rotation of the grinding hanger arms 1 for Only allow grinding hanger supports in the same plane. This can be done in the contact strip holder 5 mounted contact strip 6 rotatably about its longitudinal axis, probably in the direction of travel and at right angles to the direction of travel aus-@t-eiche.n, but not at an angle to leave the horizontal position and with dragging one side. So fulfilled the hoop pantograph all tasks placed on him with significantly improved Operational characteristics, small components, simple construction and maintenance.

Die Ausführung der Gelenke 4 und der Lagerteile 3 soll nicht an die zeichnerische Darstellung der Fig. 1 und 2 gebunden sein, hingegen kann jede beliebige anderweitige, jedoch dieselbe Aufgabe erfüllende Konstruktion vorgesehen werden.The execution of the joints 4 and the bearing parts 3 is not to the graphic representation of FIGS. 1 and 2 be bound, however, any arbitrary different, but the same task fulfilling construction can be provided.
