  Kurbeltrieb. 



   Die bisher bekannten Kurbeltriebe erforderten zur gleichmässigen stosslosen Übertragung der Kraft meist schwere   Schwungräder,   durch die wieder ein bedeutender Energieverlust durch Reibungsverluste usw. bedingt ist. 



   Die Erfindung betrifft nun einen Kurbeltrieb, der mit zwei versetzt angeordneten Kurbelschleifen ausgestattet ist, deren jede am längeren Hebelarm ein Schwunggewicht trägt. 



   Auf der Zeichnung ist der Erfindungsgegenstand in zwei Ansichten dargestellt. 



   Auf einer Achse A, welche durch einen Antrieb, z. B. Elektromotor in Umdrehung gebracht wird, sind zwei gleiche   Räder R, Rl angeordnet.   



   Jedes Rad hat am Radkranze einen zylinderförmigen Bolzen b, bl und sind die Räder so versetzt, dass die Bolzen stets einander gegenüberstehen. 



   Oberhalb der Achse A liegt die Achse T. An dieser Achse ist eine gekröpfte Welle   K,   K an der Hebel H, H drehbar befestigt sind. Jeder dieser Hebel trägt ein Schwunggewicht. Die Längenverhältnisse der Arme D,   D bzw. B, richten sich nach   dem zu erzielenden Übersetzungsverhältnis. 



   Beide Hebelarme haben an ihren Enden Kurbelschleifen F. In die   Führung   des langen Armes D 
 EMI1.1 
 Transmission T. 



   Bei Umdrehung bewegen sich infolge der Bolzen b, bl pendelartig auch die Hebelarme D,   Dl,   wodurch auch die kurzen Hebelarme E,   El   in Bewegung gesetzt, infolge dieser die Kurbel und mit dieser die Transmission zur Rotation gebracht werden. Durch die doppelte Anordnung der Kurbelschleifen bzw. der Schwunggewichte wird ein besonders sanfter, ruhiger Gang des Getriebes erreicht.

  Crank drive.



   The crank drives known up to now usually required heavy flywheels for smooth, smooth transmission of power, which again caused a significant loss of energy due to friction losses, etc.



   The invention now relates to a crank drive which is equipped with two offset crank loops, each of which carries a flyweight on the longer lever arm.



   The subject of the invention is shown in two views in the drawing.



   On an axis A, which is driven by a drive, for. B. electric motor is made to rotate, two identical wheels R, Rl are arranged.



   Each wheel has a cylindrical bolt b, bl on the wheel rim and the wheels are offset so that the bolts are always opposite one another.



   Above the axis A is the axis T. On this axis there is a cranked shaft K, K to which levers H, H are rotatably attached. Each of these levers carries a swing weight. The length ratios of the arms D, D and B depend on the transmission ratio to be achieved.



   Both lever arms have crank loops F at their ends. In the guide of the long arm D
 EMI1.1
 Transmission T.



   During rotation, the lever arms D, Dl also move in a pendulum-like manner as a result of the bolts b, bl, which also sets the short lever arms E, El in motion, as a result of which the crank and with it the transmission are made to rotate. Due to the double arrangement of the crank loops and the flyweights, a particularly smooth, quiet gear is achieved.
