Description
Reibrollenantrieb für Fahrradlichtmaschinen mit veränderlicher Übersetzung Bei den bisher bekannten Fahrradlichtmaschinen besteht der Übelstand, daß bei langsamer Fahrt oder wenn der Fahrer auf stark ansteigender Straße zu Fuß gehen muß infolge der geringen Umdrehungszahl des Ankers und der dadurch sich ergebenden geringen Spannung die Lampe nur schwach leuchtet. ' Die Erfindung bezweckt, diesen Übelstand zu beseitigen, und zwar durch Einschalten eines Reibradvorgeleges zwischen den Fahrradreifen und die Reibrolle der Lichtmaschine. Diese Anordnung ermöglicht auch die Verwendung der allgemein gebräuchlichen handelsüblichen Fahrradlichtmaschine.Friction roller drive for bicycle alternators with variable transmission In the previously known bicycle alternators there is the disadvantage that at slower Driving or when the driver has to walk on a steeply sloping road as a result the low number of revolutions of the armature and the resulting low Voltage the lamp lights only weakly. 'The invention aims to remedy this drawback to eliminate, namely by switching on a friction gear between the bicycle tires and the friction roller of the alternator. This arrangement also enables its use the commonly used commercial bicycle alternator.
Eine beispielsweise Ausführungsform des Erfindungsgegenstandes ist auf der Zeichnung veranschaulicht.An example embodiment of the subject matter of the invention is illustrated on the drawing.
Abb. i stellt den Aufriß, Abb. 2 den Grundriß dar. Die Lichtmaschine i ist um die Achse 2 in bekannter Weise schwenkbar gelagert. Die mit der Reibscheibe 6 starr verbundene Reibrolle 7 ist um ihre fest gelagerte Welle 8 schwenkbar. ' Durch ein von der Lenkstange aus zu betätigendes Gestänge i o, i i kann die Reibrolle 3 der Lichtmaschine i von dem Radreifen 4 durch eine auf der gegenüberliegenden Seite des Radreifens 4 angeordnete Reibscheibe 6 großen Durchmessers abgehoben werden. Die Wirkungsweise der Vorrichtung ist folgende: Sinkt infolge langsamer Fahrt die Ankerdrehzahl und damit die Spannung des Lichtstromes, so wird auf das Zugglied i i ein Zug ausgeübt. Der mit der Welle 8 starr verbundene Hebel i o schwingt nach oben, während sich die Reibrolle 7 gegen den Radreifen 4 anlegt, wobei gleichzeitig die Reibrolle 3 der Lichtmaschine von dem Radreifen abgehoben und somit unter Zwischenschaltung einer übersetzung angetrieben wird.Fig. I shows the front view, Fig. 2 the plan view. The alternator i is mounted pivotably about axis 2 in a known manner. The one with the friction disc 6 rigidly connected friction roller 7 can be pivoted about its fixed shaft 8. ' The friction roller can be operated by a linkage i o, i i that can be actuated from the handlebar 3 of the alternator i from the wheel tire 4 through one on the opposite Side of the wheel tire 4 arranged friction disk 6 of large diameter are lifted off. The mode of operation of the device is as follows: The Armature speed and thus the voltage of the luminous flux is applied to the tension member i i exercised a move. The lever i o, which is rigidly connected to the shaft 8, continues to oscillate above, while the friction roller 7 rests against the wheel tire 4, at the same time the friction roller 3 of the alternator is lifted off the wheel tire and thus with the interposition a translation is driven.
