Description
Bei besonders schwierigen Kommutierungsverhältniesen werden neuerdings vielfach die Kohlebürsten der Bahnmotoren unterteilt. Eis sind somit in der Halterführung zwei oder mehrere Kohlen in der Umfangsrichtung des Kollektors angeordnet. In solchen Fällen können auch Blockkohlen verwendet werden, die aus einzelnen Kohlen bestehen, welche durch Backen oder Kleben fest miteinander verbunden sind. Besonders bei dieser letztgenannten Koblebürstenausbildung treten manchmal Schwierigkeiten bei der Stromzuführung von der Bürste zum Druckfinger bzw. Kontaktstück auf.In the case of particularly difficult commutation conditions, recently often divided into the carbon brushes of the railway motors. Ice is therefore in the holder guide two or more coals arranged in the circumferential direction of the collector. In such In cases, block coals can also be used, which consist of individual coals, which are firmly connected to one another by baking or gluing. Especially with this one The latter coble brush design sometimes encountered difficulties with the power supply from the brush to the pressure finger or contact piece.
Die Erfinden - betrifft eine Einrichtung zur Stromzuführung von der Bürste zu dem auf diese drückenden Kontaktstück bei elektrischen Maschinen, insbesondere bei Bahnmotoren mit in der Umfangsrichtung des, Kbllektors. unterteilten Kohlebürsten. Erfindungsgemäß werden nun die vorerwähnten Schwierigkeiten dadurch vermieden, daß zur einwandfreien'Stromzuführung eine bewegliche und leicht lösbare Verbindung zwischen Kontaktstück und Kohlebürste vorgesehen ist.The invention - relates to a device for supplying power from the Brush to the contact piece pressing on this in electrical machines, in particular in the case of rail engines with in the circumferential direction of the Kbllektor. divided carbon brushes. According to the invention, the aforementioned difficulties are now avoided in that a movable and easily detachable connection between Contact piece and carbon brush is provided.
Die Erfindung ist in der Zeichnung in mehreren Ausführungsbeispielen veranschaulicht.The invention is shown in the drawing in several exemplary embodiments illustrated.
Bei dem Ausführungsbeispiel der Fig. i und. 2 -erfolgt die Zuführung dies Stromes von der Kohle i durch eingepreßte Litzen 2 über Steckkontakte 3 zurr -'Kontaktstück 4 des Druckfingers 5.In the embodiment of FIGS. 2 - the feed takes place this current from the carbon i through pressed-in strands 2 via plug contacts 3 zurr -'Contact piece 4 of the pressure finger 5.
Der Steckkontakt 3 kann auch gemäß Fig. 3 mit den am Druckfinger 5 vorhandenen Blattfedern ,6 verbunden werden. Zweckmäßigerweise führt man hierbei, wie die Fig.3 zeigt, den Steckkontakt3 kabelschuhartig aus. und führt ihn in eine Hohlsicke ; des Druckfingers 5 ein.The plug contact 3 can also, according to FIG. 3, be connected to the pressure finger 5 existing leaf springs, 6 are connected. Appropriately, one leads here, as Figure 3 shows, the plug-in contact 3 like a cable lug. and leads him into a Hollow bead; of the pressure finger 5.
Bei dem Ausführungsbeispiel .der Fig. q., 5 und 6 sind die. Litzen 2 fest am Kontaktstück q. des Druckfingers, 5 angebracht und lösbar, z. B. durch Steckkontakte 3, auf die Kohlei aufgesetzt.In the embodiment. Of Figs. Q., 5 and 6 are the. Strands 2 firmly on the contact piece q. of the pressure finger, 5 attached and detachable, e.g. B. by Plug contacts 3, placed on the carbon.
Die Erfindung ist nicht auf die in den Fig. i bis 6 dargestellten und vorstehend beschriebenen Ausführungsbeispiele beschränkt. Sie kann mit Vorteil bei jeder Bürsten- und Bürstenhalterbauart angewendet werden. Besonders vorteilhaft ist die erfindungsgemäße Einrichtung beispielsweise auch anwendbar bei Bürstenhaltern mit platten- oder walzenförmigen Kbntaktstücken,deren Kontaktflächen geriffelt oder gewellt sind und bei denen zwei oder mehrere Kontaktstücke in der Laufrichtung des K""ollektors hintereinander auf dem Bürstenkopf angeordnet sind.The invention is not limited to that shown in FIGS and the embodiments described above are limited. She can with advantage can be used with every type of brush and brush holder. Particularly beneficial the device according to the invention can also be used, for example, in brush holders with plate-shaped or roller-shaped contact pieces whose contact surfaces are corrugated or are corrugated and where two or more contact pieces in the running direction of the K "" ollektors are arranged one behind the other on the brush head.
