    Wechselgetriebe   für Fahrräder, insbesondere für solche mit Freilauf. 



   Die Erfindung bezieht sich auf ein Wechselgetriebe für Fahrräder, insbesondere für solche mit Freilauf, bei welchem auf der Hinterradnabe bzw. dem   Antriebskörper   verschieden grosse Kettenräder 
 EMI1.1 
 weiters ermöglicht, die gebräuchlichen Fahrräder mit   dem Wechselgetriebe auszustatten,   und kennzeichnet sich dadurch, dass das auf seinem Träger aufgeschraubte und durch einen Ring mit Gegengewinde festgehaltene grösste Kettenrad die vorteilhaft aus einem Stück bestehenden kleineren Kettenräder mittels Schraubenbolzen unter Anordnung von Distanzringen freischwebend trägt. 



   In der Zeichnung ist eine beispielsweise    Ausführungsform.   der Erfindung, teilweise im Schnitt, dargestellt. 



   Das grösste Kettenrad 3 ist auf   seinem Träger 11 (Hinterradnabe,   Antriebskörper des Freilaufes) aufgeschraubt und durch einen Ring 14 mit Gegengewinde festgehalten. Die vorteilhaft aus einem Stück bestehenden kleineren Kettenräder 2 und 4 sind mittels Schraubenbolzen 16 freisehwebend an dem grössten Kettenrad 3 angebracht und durch Distanzringe   17   in gewollter Entfernung von demselben gehalten.

    Change gears for bicycles, especially for those with freewheel.



   The invention relates to a change gear for bicycles, in particular for those with a freewheel, in which chain wheels of different sizes on the rear wheel hub or the drive body
 EMI1.1
 It also makes it possible to equip common bicycles with the change gear, and is characterized by the fact that the largest sprocket screwed onto its carrier and held in place by a ring with mating thread carries the smaller sprockets, which are advantageously made of one piece, floating freely by means of screw bolts with spacer rings.



   In the drawing is an example embodiment. of the invention, partly in section, shown.



   The largest sprocket 3 is screwed onto its carrier 11 (rear wheel hub, drive body of the freewheel) and held in place by a ring 14 with a mating thread. The smaller sprockets 2 and 4, which advantageously consist of one piece, are attached to the largest sprocket 3 in a freely suspended manner by means of screw bolts 16 and are held at a desired distance therefrom by spacer rings 17.
