Abstract
Die Erfindung betrifft eine Kettenschaltung für Fahrräder, umfassend eine treibende und eine getriebene Kettenradeinheit, eine Kette zur Übertragung der Antriebskraft sowie einen Kettenumwerfer zum Einleiten des Schaltvorganges, wobei am jeweils größeren Kettenrad mindestens eine Zahngruppe mit einem Referenzzahn, einem nachfolgenden Zahn und mindestens einem Fangzahn angeordnet ist, die über eine geeignete Zahnform zur Verbesserung des Schaltvorganges vom kleineren zum größeren Kettenrad und zur Reduzierung des Schaltgeräusches verfügen. Maßnahmen zur Geräuschreduzierung sind: seitliche Aussparung am Referenzzahn, Abweisfase und Auslauffase oder Aussparung am nachfolgenden Zahn sowie eine relativ große Anfasung im mittleren Bereich der Außenkante an der Innenlasche.
