Description

Durch die Erfindung wird' ein, Schaltwerk mit beweglichen Eimgriffsstücken geschaffen, bei dem die Eingriffsstücke leicht auszuwechseln sind. Hierbei ist es gleiclh, ob die Eingriffsstücke als Rollen, Kugeini oder 'Blinken ausgebildet sind.The invention 'creates a' rear derailleur with movable grip pieces, in which the engaging pieces are easy to replace. It is the same whether the engaging pieces are designed as roles, Kugeini or 'blinking.

Aus den Zeichnungen ist die Wirkungsweise der Einrichtung ersichtlich'.
Auf Welle ι (Abb. ι und 2) sitzt mit dieser fest verbunden ein gezahntes Rad 2, auf dessen Seitennabeni 3, 3 ein mit Rollen 4, 4 versehener Schaltring 'hin und her drehend schwingen kann. Diese Schalteinrichtung besteht aus zwei Fiihrungsseheiben 5, 5, /welche die mit Schlitzen versehenen Lagerscheibeni 6, 6 beim Schwingen mit in Bewegung setzen. In den Schlitzen. 7, 7 dieser Lagerstiheibeni sind RoMen4, 4 eingelagert, die rechts undi links in denselben geführt werden, mit ihrem! mittleren Teil jedoch im den Kerben des gezahnten Rades liegen. Über sämtliche Rollen hinweg läuft ein elastisches Band 8, welches dieselben auf ihrem Sitz preßt, beim Schwingern der Schalteinrichtung aber, dem Hub der schrägen Zahnflächen entsprechend nachgibt, nach Überwindung der höchsten Zahneteile jedoch die Rollen wieder auf ihren Sitz drückt. In Abb. 3 ist die Lagerung der Rollen im vergrößertem Maß dargestellt. The operation of the device can be seen from the drawings.
On shaft ι (Fig. Ι and 2) sits firmly connected to this a toothed wheel 2, on the side hub 3, 3 of a switching ring provided with rollers 4, 4 can swing back and forth rotating. This switching device consists of two guide disks 5, 5 / which set the bearing disks 6, 6 provided with slots in motion when they swing. In the slots. 7, 7 of these Lagerstiheibeni are RoMen4, 4 stored, which are guided right and left in the same, with their! middle part, however, lie in the notches of the toothed wheel. An elastic band 8 runs over all the rollers, which presses them on their seat, but when the switching device vibrates, it gives way to the stroke of the inclined tooth surfaces, but after overcoming the highest tooth parts presses the rollers back onto their seat. In Fig. 3 the bearing of the rollers is shown on an enlarged scale.

In gleicher Weise wie mit Rollen ist auch eine Übertragung der Kraft mit Kugeln möglich. Abb. 4 zeigt eine solche Anordnung in vergrößertem Maßstab·.In the same way as with rollers, the force can also be transmitted with balls. Fig. 4 shows such an arrangement on an enlarged scale.
