Description

Es sind bereits auswechselbare, geteilte Kettenräder für Fahrräder bekannt. Ebenso sind Fahrräder bekannt, deren auswechselbarer, geteilter Zahnkranz in einer Ringnut der Nabe befestigt ist.Interchangeable, split chain wheels for bicycles are already known. as well bicycles are known whose interchangeable, split ring gear in an annular groove the hub is attached.

Die vorliegende Erfindung betrifft einen auswechselbaren, geteilten Kettenrad-Zahnkranz für Fahrräder, der sich durch eine einfache Befestigung in der Ringnut seiner Nabe ίο vorteilhaft von den bekannten Ausführungen unterscheidet. Diese Befestigung besteht darin, daß die eine Zahrikranzhälfte durch bajonettverschlußartige Schlitze mit den an der Nabe sitzenden Stiften und die andere Zahnkranzhälfte durch an Flachfedern sitzende Stifte mit der Nabe lösbar gekuppelt ist.The present invention relates to a replaceable, split sprocket ring gear for bicycles, which is characterized by a simple Fastening in the annular groove of its hub ίο advantageous from the known designs differs. This attachment consists in the fact that the one Zahrikranz half by bayonet lock-like Slots with the pins sitting on the hub and the other half of the sprocket through pins sitting on flat springs Pins is releasably coupled to the hub.

In der Zeichnung ist die Erfindung beispielsweise dargestellt, und zwar zeigenIn the drawing, the invention is shown as an example, namely show

Abb. 3 einen Schnitt nach Linie A-B der Abb. 2.Fig. 3 is a section along line AB in Fig. 2.

Die Nabe α ist mit einer Ringnut k versehen und wird in bekannter Weise auf der Hinterradnabe befestigt. In der Nabe α sind Stifte b und c eingenietet, welche durch die Nut k führen. Mittels der Stifte c sind zwei Flachfedern ei an der Nabe drehbar befestigt. Diese Flachfedern tragen je einen Stift e. Die Nabe α ist außerdem mit zwei Löchern h versehen, die mit den beiden Löchern i der einen Zahnkranzhälfte Z2 übereinstimmen. Die Zahnkranzhälfte Z1 hat zwei winklig geführte Schlitze f, die wiederum mit den Stiften i> der Nabe α übereinstimmen. Der Zusammenbau des Kettenrades geschieht in folgender Weise: Man schiebt die Zahnkranzhälfte Z1 so in die Nut k der Nabe, daß die Stifte b in die Schlitze f gleiten. Durch eine kleine Drehung der Nabe werden die Stifte b bis ans Ende der Schlitze/ gebracht. Jetzt schiebt man die andere Hälfte Z2 des Zahnkranzes in die Nut k gegen die Hälfte I1, so daß die Stifte c in die Schlitze g gleiten, und kuppelt die Nabe α mit der Hälfte I2 durch Verdrehen der Federn d derart, daß die Stifte e durch die die Löcher h und die Löcher i hindurchgehen. Die beiden Zahnkranzhälften sind nunmehr mit ihrer Nabe festgekuppelt.The hub α is provided with an annular groove k and is attached to the rear wheel hub in a known manner. Pins b and c are riveted into the hub α and lead through the groove k. Two flat springs ei are rotatably attached to the hub by means of the pins c. These flat springs each carry a pin e. The hub α is also provided with two holes h which coincide with the two holes i of one sprocket half Z 2 . The ring gear half Z 1 has two angled slots f, which in turn coincide with the pins i> of the hub α . The assembly of the sprocket is done in the following way: The ring gear half Z 1 is pushed into the groove k of the hub in such a way that the pins b slide into the slots f. By turning the hub slightly, the pins b are brought to the end of the slots /. Now you push the other half Z 2 of the ring gear into the groove k against half I 1 , so that the pins c slide into the slots g , and the hub α is coupled to the half I 2 by twisting the springs d in such a way that the Pins e through which holes h and holes i pass. The two ring gear halves are now firmly coupled with their hub.
