Spreizstücke für Bremsbacken, die derart beweglich sind, daß die auf die Backen übertragenen Drücke sich ausgleichen, sind bekannt. Die bisherigen Anordnungen zeigen jedoch keine Einrichtung, um die Folgen der Abnutzung an den arbeitenden Flächen beseitigen zu können. Dadurch kommen im Laufe der Zeit die Keilflächen der Spreizstücke unter immer anderen Winkeln gegenüber den entsprechenden Flächen der Bremsbacken zur Wirkung, so daß der Bremsdruck, der sich mit der Tangente dieser Winkel ändert, gleichfalls im Laufe der Zeit eine beträchtliche Änderung erfährt.Spreader pieces for brake shoes, which are movable in such a way that the transferred to the shoes Pressures to equalize are known. However, the previous arrangements show no facility to deal with the consequences of the To be able to remove wear and tear on the working surfaces. As a result, the wedge surfaces of the spreader pieces appear over time always at different angles to the corresponding surfaces of the brake shoes to the effect, so that the brake pressure, which changes with the tangent of this angle, also changes over time undergoes a considerable change.
Die vorliegende Erfindung besteht darin, daß das Spreizstück aus zwei Teilen besteht, die so miteinander verbunden sind, daß die Gesamtlänge des Spreizstückes stets auf das richtige Maß, entsprechend dem günstigsten Winkel, eingestellt werden kann.The present invention consists in that the spreader consists of two parts, which are connected to each other in such a way that the total length of the expansion piece is always on the correct dimension, according to the most favorable angle, can be set.
Die Zeichnung zeigt den Gegenstand der Erfindung in drei Figuren, und zwar ist Fig. ι die Gesamtansicht einer Bremse, während Fig. 2 das Spreizstück im Querschnitt und Fig. 3 dasselbe im Grundriß im vergrößerten Maßstabe zeigen.The drawing shows the subject matter of the invention in three figures, namely is Fig. Ι the overall view of a brake, while Fig. 2 shows the expansion piece in cross section and Fig. 3 shows the same in plan on an enlarged scale.
b und c sind die Bremsbacken, die um den Zapfen α drehbar angeordnet sind, d und e die zur Übertragung der Bremsdrücke bestimmten Endflächen dieser Backen. Das Spreizstück, das in einem Schlitz der Welle g frei verschiebbar angeordnet ist, besteht aus den beiden Teilen k und Z, von denen k mit Schrauben- und / mit Muttergewinde versehen ist, so daß durch Hineinschrauben von k in / die. Gesamtlänge des Spreizstückes verändert werden kann. Eine Schraube i, die durch die beiden Teile k und I hindurchgesteckt und gleichzeitig in der. Welle g gelagert ist, dient dazu, das Herausfallen des Spreizstückes aus dem Wellenschlitz zu verhindern. b and c are the brake shoes, which are rotatably arranged around the pin α , d and e are the end faces of these shoes intended to transmit the braking pressures. The expansion piece, which is arranged freely displaceably in a slot in the shaft g , consists of the two parts k and Z, of which k is provided with screw and / with nut threads, so that by screwing k into / the. Total length of the expansion piece can be changed. A screw i that pushed through the two parts k and I and at the same time in the. Shaft g is mounted, serves to prevent the expansion piece from falling out of the shaft slot.
