Description

Schleifstückträger mit U-förmigem Querschnitt für Stromabnehmer elektrischer Fahrzeuge. Um bei Stromabnehmern elektrischer Fahrzeuge das Schleifstück möglichst weit abnutzen zu können, werden besondere Schleifstückträger verwendet, die aus Blech derart zusammengebogen sind, daß sie die für den Betrieb erforderliche Widerstandsfähigkeit und leichtes Gewicht aufweisen. Es ist bereits vorgeschlagen worden, dem Schleifstückträger einen U-förmigen Querschnitt zur Aufnahme des Schleifstückes zu geben.Contact strip carrier with U-shaped cross-section for electrical current collectors Vehicles. In order to use the contact strip in pantographs of electric vehicles as much as possible To be able to wear far away, special contact strip carriers are used, which are made of Sheet metal are bent together so that they have the resistance required for operation and be light in weight. It has already been proposed to use the contact strip carrier to give a U-shaped cross-section for receiving the contact strip.

Damit eine sichere Befestigung des Schleifstückes mit dem Träger erzielt wird, wird dieser gemäß der Erfindung an den Winkelstellen seines Querschnitts nicht scharf oder in Form eines kurzen Kreisbogens umgebogen, sondern es werden dort Ausbuchtungen angebracht. Durch diese Ausbuchtungen wird eine gute Federung der Verbindung und ein genügender Anpressungsdruck auf das Schleifstück erzielt. Zur weiteren Verbesserung der Federung können die Winkelstellen in Abständen durch Ausnehmungen unterbrochen werden. Dieses ergibt gleichzeitig eine Gewichtsverminderung, die außerdem noch durch Längslöcher im Steg erhalten werden kann.This ensures that the contact strip is securely fastened to the carrier is, this is not according to the invention at the angular points of its cross-section sharply or bent in the form of a short circular arc, but there are bulges there appropriate. These bulges ensure good suspension of the connection and A sufficient contact pressure is achieved on the contact strip. For further improvement the suspension, the angular points can be interrupted at intervals by recesses will. This results in a weight reduction at the same time, which also still can be obtained through longitudinal holes in the web.

In der Zeichnung ist ein Ausführungsbei-,spiel der Erfindung dargestellt. In Abb. i, einem Querträger, ist a der Schleifstückträger und b das eingeschobene Schleifstück.In the drawing, an exemplary embodiment is shown, game of the invention. In Fig. I, a cross member, a is the contact strip carrier and b is the inserted one Contact strip.

Abb. 2 und 3 zeigen in einer Seitenansicht und in einem Grundriß den- Schleifstückträger allein. Die .Seitenteile des Trägers sind mit dem Steg durch Ausbuchtungen c verbunden, d sind die Ausnehmungen an den Winkelstellen und e die im Steg.Fig. 2 and 3 show in a side view and in a plan the- Contact strip carrier alone. The side parts of the carrier are through with the web Bulges c connected, d are the recesses at the angles and e are the in the jetty.

Das Schleifstück b wird in den Träger in der Längsrichtung zweckmäßig unter Verwendung einer Spindelpresse o. dgl. eingeschoben.The contact strip b is expedient in the carrier in the longitudinal direction using a screw press or the like.
