Abstract
Description
Die Erfindung betrifft die Zahnkränze am Fahrradhinterradan trieb, die beweglich auf einer verzahnten Welle sitzen und sich vertikal verschieben lassen, insbesondere für Fahrräder.The invention relates to the sprockets on the rear bicycle wheel driven, which sit and move on a toothed shaft can be moved vertically, especially for bicycles.
Die Zahnkränze auf einer verzahnten Achse sollen sich verschie ben lassen, um den sich bei starrer Verbindung ergebenden Winkel zwischen optimaler Parallellage der Kette mit den Zahnkränzen und der Schräglage der Kette nach Schalten auf nächstgrößeren Zahnkranz zu vermeiden.The sprockets on a toothed axis should shift allow for the result of a rigid connection Angle between the optimal parallel position of the chain with the Sprockets and the inclined position of the chain after shifting on to avoid the next larger sprocket.
Es ist bis jetzt bekannt, daß die herkömmlichen und derzeit üb lichen Fahrradhinterradantriebe mit festsitzenden Zahnkränzen ausgestattet sind.It is known so far that the conventional and currently over bicycle rear wheel drives with fixed sprockets are equipped.
Die jetzigen Konstruktionen am Fahrradhinterradantrieb weisen keine optimale Kettenführung auf.The current constructions on the rear wheel drive show no optimal chain guide.
Der Erfindung liegt die Aufgabe zugrunde, eine einfache und op timale Kettenführung zu gewährleisten.The invention has for its object a simple and op to ensure maximum chain guidance.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Zahnkränze vertikal beweglich auf einer verzahnten Welle sich bewegen und sich verschieben lassen.This object is achieved in that the Sprockets vertically movable on a toothed shaft themselves move and move.
Dadurch wird ein exakter Geradeauslauf der Kette ermöglicht.This enables the chain to run straight ahead.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit beweglichen Zahnkränzen auf einer verzahnten Welle ein Geradeauslauf der Kette gewährleistet wird und dadurch ein geringerer Verschleiß an Kette und Zahnkränzen auftritt, Energie und Kraftaufwand eingespart wird und sich die Laufgeräusche senken.The advantages achieved with the invention are in particular in that with movable sprockets on a toothed Shaft a straight running of the chain is guaranteed and this means less wear on the chain and sprockets occurs, energy and effort is saved and the Reduce running noise.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dar gestellt und wird wie folgt beschrieben. Die Zeichnung zeigt eine Kette am Fahrrad, die vom vorderen Zahnrad zu den hinten nebeneinanderliegenden Zahnkränzen führt. In Abhängigkeit von der Wahl des hinteren Zahnkranzes, entsteht zwischen der optimalen Parallellage der Kette mit dem vorderen und dem hinteren Zahnkranz ein Winkel. Dieser Winkel ist in optimaler Lage gleich Null. Indem sich auf der Welle die Zahnkränze verschieben lassen, wird sich die Kette so einlaufen, daß sich ein Winkel von =0 ergibt. Das Verschieben der Zahnkränze wird erreicht - wie in der Zeichnung vergrößert dargestellt - mit einer verzahnten Welle.An embodiment of the invention is shown in the drawing and is described as follows. The drawing shows a chain on the bike running from the front gear to the rear adjacent sprockets leads. In dependence of the choice of the rear sprocket arises between the optimal parallel position of the chain with the front and the rear sprocket an angle. This angle is optimal Position zero. By placing the sprockets on the shaft can be moved, the chain will shrink so that an angle of = 0 results. Moving the sprockets will reached - as shown enlarged in the drawing - with a toothed shaft.
