Abstract
Zweiradkette mit den Zähnen auf der Kette Die Zähne sind, im Gegensatz zu üblichen Systemen, auf der Kette, diese greifen in die Kassette. Die Kette kann schmaler gebaut werden, da sie keine Zähne von Kettenblatt oder Ritzel aufnehmen muss.Two-wheeled chain with the teeth on the chain The teeth are, unlike conventional systems, on the chain, these grab in the cassette. The chain can be made narrower because it does not have to pick up teeth from the chainring or pinion.
Description
Stand der Technik:State of the art:
Die Spreizung der Kassetten für Kettenschaltungen wird, insbesondere bei Verwendung von nur einem Kettenblatt immer größer. Stand der Technik sind 11 Ritzel am Hinterrad. Durch die große Spreizung werden die Sprünge zwischen den Gängen größer. Für eine Optimale Trittfrequenz ist eine feine Abstufung allerdings besser. Um die Gangsprünge zu verringern müsste die Anzahl der Ritzel erhöht werden. Bei gleichbleibender Kassettenbreite ist eine Steigerung der Anzahl der Ritzel begrenzt.The spread of the cassettes for derailleurs is always larger, especially when using only one chainring. The state of the art 11 pinions on the rear wheel. The large spread increases the jumps between the courses. For a perfect cadence a fine gradation is better. In order to reduce the gear jumps, the number of pinions would have to be increased. With the same cassette width, an increase in the number of pinions is limited.
Erfindung:Invention:
Durch das Umdrehen des Prinzips, die Zähne sitzen auf der Kette anstatt auf den Ritzeln lässt sich die Kette schmaler bauen. Durch eine Schmalere Kette können mehr Ritzel nebeneinander angeordnet werde, dadurch verringern sich die Übersetzungssprünge (der Übersetzungsfaktor zischen den Ritzeln). Werden die Zähne Asymmetrisch angeordnet, das heißt, in Richtung der größer werdenden Ritzel verschoben, wird eine noch engere Abstufung der Gänge möglich.By reversing the principle that the teeth sit on the chain instead of the sprockets, the chain can be made narrower. By a narrower chain more pinions can be arranged side by side, thereby reducing the translation jumps (the translation factor hiss the pinions). If the teeth are arranged asymmetrically, that is, shifted in the direction of the increasing pinion, an even tighter gradation of the gears is possible.
Es können herkömmliche Schaltwerke verwendet werden, es müssen nur die Schaltröllchen angepasst werden. It can be used conventional derailleur, it must be adapted only the pulleys.

Patentanspruch 2: Zweiradkette mit den Zähnen auf der Kette, asymmetrisch angeordnetClaim 2: bicycle with the teeth on the chain, arranged asymmetrically
Variante 1:Version 1:
asymmetrische Kette mit Kettengliedern bei der die mittlere Lasche und die Lasche in Fahrtrichtung links mit jeweils einem Zahn ausgerüstet ist. Die Zähne beider Laschen sind dabei so gekröpft, daß sie in einer Spur liegen.
(Durch die Asymmetrie steigt die mögliche Anzahl der Gänge auf ca. 14, bei einem 10/11fach Freilaufkörper.)
asymmetrical chain with chain links in which the middle lug and the lug in the direction of travel on the left are equipped with one tooth each. The teeth of both tabs are so bent that they lie in a track.
(Due to the asymmetry, the possible number of gears increases to about 14, with a 10/11 freewheel body.)
Variante 2:Variant 2:
asymmetrische Kette mit Kettengliedern bei der die mittlere Lasche und die Lasche in Fahrtrichtung links mit jeweils einem Zahn ausgerüstet ist. Der Zahn der mittlere Lasche ist dabei so gekröpft, daß er mit dem Zahn der äußeren Lasche in einer Spur liegt.
(Durch die Asymmetrie steigt die mögliche Anzahl der Gänge auf 16, bei einem 10/11fach Freilaufkörper.)
asymmetrical chain with chain links in which the middle lug and the lug in the direction of travel on the left are equipped with one tooth each. The tooth of the middle tab is so bent that it lies with the tooth of the outer tab in a track.
(Due to the asymmetry, the possible number of gears increases to 16, with a 10/11 freewheel body.)
