Description

Es sind einige Ausführungsformen von Kohleschleifbügeln für Stromabnehmer elektrischer Triebfahrzeuge bekannt, die mit Spanndrähten versehen sind, um die Biegefestigkeit der Kohleschleifleiste zu erhöhen. Diese Spanndrähte liegen normalerweise in der unteren Hälfte der Kohleschleifleiste und sind entweder seitlich oder von der Unterkante der Schleifleiste her in dafür vorgesehenen Rillen eingelagert und zweckmäßig durch eine Vergußmasse kraftschlüssig mit der Kohleschleifleiste verbunden.There are some embodiments of carbon pads for pantographs electric traction vehicles known which are provided with tension wires to the To increase the flexural strength of the carbon contact strip. These tension wires are usually lying in the lower half of the carbon contact strip and are either to the side or from the lower edge of the contact strip is stored in the grooves provided and expediently positively connected to the carbon sliding strip by a potting compound.

In Fällen mit geringer Abnutzhöhe oder mit schwachem Kohleprofil hat es sich erwiesen, daß eine zu starke Schwächung eintreten würde und die Spanndrähte ganz an den Rand der eigentlichen Kohleschleifleiste zu legen wären.In cases with a low wear height or with a weak carbon profile it turned out that too much weakening would occur and the tension wires should be placed right at the edge of the actual carbon contact strip.

Nach der Erfindung werden deshalb an der eigentlichen Köhleschleifleiste längs laufende Verstärkungsrippen oder -wülste vorgesehen, in denen die Spanndrähte in die dafür vorgesehenen Rillen eingelegt und gegebenenfalls durch Ausgießen kraftschlüssig mit der Kohleschleifleiste verbunden sind.According to the invention, therefore, on the actual Köhl grinding strip longitudinal reinforcement ribs or beads are provided in which the tension wires placed in the grooves provided for this purpose and, if necessary, frictional by pouring are connected to the carbon contact strip.

In der Zeichnung sind zweiAusführungsbeispiele für Kohleschleifbügel nach der Erfindung dargestellt. Fig. r zeigt eine Kohleschleifleiste a im Querschnitt, an deren Unterseite zwei Längsrippen b angearbeitet oder angepreßt sind, die jeweils mit einer Rille c, in die der Spanndraht d eingelegt und durch eine Vergußmasse c mit der Kohleschleifleiste a kraftschlüssig verbunden ist, versehen sind.The drawing shows two exemplary embodiments for carbon sanding bars shown according to the invention. Fig. R shows a carbon contact strip a in cross section, on the underside of which two longitudinal ribs b are incorporated or pressed, each with a groove c into which the tension wire d is inserted and through a potting compound c is positively connected to the carbon contact strip a, are provided.

Fig. 2 zeigt gleichfalls eine Kohleschleifleiste a im Querschnitt, an deren Unter- bzw. Außenseite mehrere Wülste bzw. Längsrippen b angebracht sind, die wiederum mit je einer Rille c zur Aufnahme des Spanndrahtes d versehen sind. Auch hier sind die Spanndrähte d durch eine Vergußmasse e kraftschlüssig mit der Kohleschleifleiste a verbunden.Fig. 2 also shows a carbon contact strip a in cross section, on the underside or outside of which several beads or longitudinal ribs b are attached, which in turn are each provided with a groove c for receiving the tension wire d. Here, too, the tension wires d are frictionally engaged with the potting compound e Carbon contact strip a connected.
