KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der nachstehend beschriebene Vorderradantrieb gestattet ein Fahren sowohl mit wie auch ohne Uebersetzung. Vorrichtungen zur Aenderung der Uebersetzung unter Anwendung rückkehrender Räderwerke, welch letztere ein- oder ausgerückt werden können, sind zwar bekannt; das wesentliche Merkmal der Erfindung ist jedoch darin zu sehen, dafs die Vorgelegewelle im Gestell verschiebbar gelagert ist und ein in der Treibradnabe gelagerter Riegel bei ausgerücktem Vorgelege das Treibrad mit dem auf der Tretkurbelwelle sitzenden Zahnrade kuppelt.The front-wheel drive described below allows driving both with and even without translation. Devices for changing the translation using returning gear trains, which the latter can be engaged or disengaged, are known; the essential feature of the invention, however, is to be seen in the fact that the countershaft is slidably mounted in the frame and a bolt mounted in the drive wheel hub When the back gear is disengaged, the drive wheel with the gear wheel sitting on the crankshaft clutch.
Die Wirkung ist bei eingerückter Uebersetzung folgende:The effect is as follows when the translation is indented:
Durch die Drehung der Tretkurbelachse setzt das auf dieser Achse festsitzende Zahnrad Z das kleine Zahnrad η in Bewegung. Da das grofse Zahnrad m mit dem Zahnrad η zu einem Doppelzahnrade fest verbunden ist, so setzt hiernach das Zahnrad m das kleine Zahnrad 0 ebenfalls in Bewegung, welch letztere naturgemä'fs in derselben Richtung erfolgt, wie bei den Tretkurbeln, wobei aber die Drehung der Nabe durch die übersetzende Bewegung verstärkt worden ist, so dafs, obgleich die Tretkurbelachse selbst rotirt, die Nabe dennoch die Achse in der Drehung überholt und so einen schnelleren Gang des Fahrrades sichert.As a result of the rotation of the crank axle, the gear Z fixed on this axle sets the small gear η in motion. Since the large cogwheel m is firmly connected to the cogwheel η to form a double cogwheel, the cogwheel m then also sets the small cogwheel 0 in motion, the latter naturally occurring in the same direction as with the pedal cranks, but with the rotation of the The hub has been reinforced by the translating movement, so that, although the crank axle itself rotates, the hub nevertheless overtakes the axle in rotation and thus ensures a faster gear of the bicycle.
Dieser durch die Uebersetzuug erreichte schnellere Gang des Fahrrades nützt in dem Falle nichts, wenn es sich um ein Passiren von langen und steilen Steigungen handelt, weil in diesem Falle das Fahren durch die Uebersetzung um so mehr erschwert wird, je gröfser die Uebersetzung ist. In diesem Falle wird die Uebersetzung ganz ausgeschaltet, was durch Lösen der Schraube g und Herunterlassen der Achse f bis zum Querriegel r geschieht. (Eine kurze Drehung der Schraube g genügt, um diese Achse fest in der Stellung zu halten.) Durch diese Bewegung haben sich die Zahnräder in senkrechter Richtung von einander entfernt und die Nabe ist frei geworden. Um das Fahren zu ermöglichen, wird die Nabe mit der Tretkurbelachse fest verbunden, indem man den Riegel ρ quer durch die Nabenscheiben durchschiebt, bis sein Ende in den Zahnkranz des Zahnrades / eingreift. Eine Sperrfeder schützt den Riegel vor willkürlicher Bewegung.This faster gear speed of the bicycle achieved by the translation is of no use in the case of long and steep inclines, because in this case driving is made more difficult by the translation, the greater the translation. In this case, the translation is completely switched off, which is done by loosening the screw g and lowering the axis f to the crossbar r. (A short turn of the screw g is sufficient to hold this axis firmly in position.) This movement has caused the gears to move away from each other in a vertical direction and the hub has become free. In order to enable driving, the hub is firmly connected to the crank axle by pushing the bolt ρ across the hub washers until its end engages in the ring gear of the gearwheel /. A locking spring protects the bolt from arbitrary movement.
