Description

Stromabnehmerbügel für elektrische Fahrzeuge mit drehbarem Kohlenschleifstück. Im Patent 315436 ist eire Stromabnehmerbügel mit drehbarem Kohlenschleifstück in Dreikantform beschrieben, dessen Kohlenformstücke auf zwei ineinandergeschobene Rohre aufgeschoben sind, von denen das äußere Rohr die Verdrehung der Schleiffläche übernimmt, während das innere Rohr als Lagerung -dient. Es hat sich nun gezeigt, daß im Betrieb häufig eine Schleiffläche gegenüber anderen längere Zeit am Fahrdraht bleibt und durch einseitiges Abschleifen eine Verschiebung des Schwerpunktes aus der Mittelachse des Schleifstückes entsteht. Je mehr sich eine Schleiffläche abnutzt, desto größer wird diese Verschiebung, desto größer aber auch die Schwierigkeit, die beiden übrigen -Schleifflächen zur Anlage zu bringen. Die Verschiebung des ,Schwerpunktes hat also auch .gewisse Vorzüge, und es ist wünschenswert, diese Erkenntnis so auszunutzen, daß die Nachteile der einseitigen Abnutzung des Schleifstückes vermieden werden. Dies wird erreicht durch eine verstellbare exzentrische Lagerung der Drehachse, die es ermöglicht, eine bestimmte Schleiffläche zur -Anlage an den Fahrdraht zu. bringen.Current collector bracket for electric vehicles with a rotatable carbon grinder. In the patent 315436 there is a current collector bracket with a rotatable carbon scraper in Triangular shape described, its shaped carbon pieces on two nested Pipes are pushed on, of which the outer pipe is twisting the grinding surface takes over, while the inner tube serves as storage. It has now been shown that in operation often a grinding surface compared to others for a longer period of time on the contact wire remains and a shift in the center of gravity is prevented by one-sided sanding the central axis of the contact strip is created. The more a sanding surface wears, the greater this shift, but the greater the difficulty Bring the two remaining grinding surfaces into contact. The shift of the, center of gravity thus also has certain advantages, and it is desirable to exploit this knowledge in such a way that that the disadvantages of one-sided wear of the contact strip are avoided. This is achieved by an adjustable eccentric bearing of the axis of rotation, which makes it possible to use a certain grinding surface to attach to the contact wire. bring.

Die Erfindung ist in der Zeichnung veranschaulicht. Die Buchse A ist mit drei Gewindelöchern a'-, az, a3 für die Einstellschraube G versehen und, mit dem Rohr B fest verschraubt. Die Buchse C ist auf der Buchse A drehbar und durch die Schraube G verstellbar .gelagert. Am anderen Ende besitzt die Buchse C eine exzentrische Bohrung, welche als Lager für den Zapfen E dient. Rohr D verbindet die Endstücke F des Bügels. Dadurch wird das Schleifstück versteift und eine parallele Lage der Achse des Schleifstückes zu den Achsen. der Bügelenden erreicht.The invention is illustrated in the drawing. The socket A is provided with three threaded holes a'-, az, a3 for the adjusting screw G and, with screwed tightly to tube B. The socket C is rotatable on the socket A and through the screw G is adjustable. At the other end, the socket C has one eccentric hole, which serves as a bearing for the journal E. Pipe D connects the end pieces F of the bracket. This stiffens the contact strip and makes it parallel Position of the axis of the contact strip to the axes. of the temple ends.

Der Bügel .ist durch die exzentrische Lagerung der Drehachse in seiner Drehbarkeit nicht behindert, denn er kann sich. in Unterführungen usw. beliebig selbst um die ganze Achse drehen und wird sich infolge der Lage seines Schwerpunktes immer wieder mit der eingestellten Schleiffläche an den Fahrdraht anlegen.The bracket .is due to the eccentric mounting of the axis of rotation in his Rotation is not hindered because it can move. in underpasses etc. any itself rotate around the whole axis and will vary as a result of the location of its center of gravity always apply the set grinding surface to the contact wire.
