Description

Den Gegenstand der Erfindung bildet ein Hilfsmotorantrieb für Fahrräder od. dgl., bei welchem der Motor direkt mit dem Kettenzahnkranz gekuppelt werden kann.The subject of the invention is an auxiliary motor drive for bicycles or the like, in which the motor is coupled directly to the sprocket can.

Die Voraussetzung für einen solchen Antrieb ist, daß die Tretkurbelachse bzw. die Tretkurbeln getrennt vom Zahnkranz gelagert sind, damit sie vom angetriebenen Zahnkranz nicht beeinflußt werden.The prerequisite for such a drive is that the crank axle or the cranks are stored separately from the ring gear so that they are driven by the Ring gear are not affected.

Die beiden Tretkurbeln können in bekannter Weise auch unabhängig voneinander angeordnet sein.The two cranks can also be used independently of one another in a known manner be arranged.

Die Abbildung zeigt einen solchen Antrieb, bei welchem das Antriebsritzel a zwischen dem oberen und dem unteren Trum der Antriebskette b in den frei liegenden Zähnen des Kettenzahnrades c angeordnet ist und beim Gebrauch der Pedale d ausgerastet werden kann, indem diese das in Leerlaufstellung befindliche Zahnrad c mitnehmen.The figure shows such a drive, in which the drive pinion a is arranged between the upper and lower run of the drive chain b in the exposed teeth of the chain sprocket c and can be disengaged when the pedals d are used, in that the gear c is in the idle position take along.
