Abstract

Beim Getriebe im Sinne der Erfindung wird durch eine rotierende Kurbel (1) über eine Koppelstange (2) ein Hebel (3) in eine Pendelbewegung versetzt. Ein Seil (4) wird, einfach oder mehrfach, vom Hebel (3) bzw. von einer Rolle (5) am Hebel zu einer Umlenkrolle (6) geführt und von dort weiter zu einer Spule (7). Je nach Position der Umlenkrolle (6) wird der Seilabschnitt zwischen pendelndem Hebel (3) und Umlenkrolle (6) im Getriebebetrieb mehr oder weniger stark verlängert und wieder verkürzt. Durch die Verlängerung des Seiles (4) wird die Spule (7) in Rotation versetzt und gibt über einen Freilauf Ihre Drehbewegung an das Antriebsrad des Fahrrades weiter. Die Spule (7) verfügt weiters über eine Rückstellfeder, mit deren Hilfe sich das periodisch verkürzende Seil (4) wieder aufrollt. Das Übersetzungsverhältnis des Getriebes wird durch eine Veränderung der Position der Umlenkrolle (6) eingestellt.In the transmission according to the invention, a rotating crank (1) sets a lever (3) in a pendulum motion via a coupling rod (2). A rope (4) is fed, single or multiple, from the lever (3) or from a roller (5) on the lever to a deflection roller (6) and from there on to a spool (7). Depending on the position of the deflection pulley (6), the rope section between the oscillating lever (3) and the deflection pulley (6) is lengthened to a greater or lesser extent and then shortened again in gear operation. By lengthening the rope (4), the spool (7) is set in rotation and transmits its rotational movement to the drive wheel of the bicycle via a freewheel. The spool (7) also has a return spring, with the help of which the periodically shortening rope (4) rolls up again. The transmission ratio of the gear unit is set by changing the position of the pulley (6).
