Abstract

The motor drive is from a small motor, preferably an electric motor and has a chain or gear drive to a hub wheel. The transmission incorporates a freewheel effect for ease of operation and a simpler cycling control. An alternative arrangement has a large gear rim fitted to the wheel rim, or to the spokes, driven by the gear wheel on the motor shaft. The gear wheels are brought into mesh by an axially moving clutch for a simple freewheel effect. In the latter arrangement the thrust of the drive motor is compensated by pressure roller on the other side of the wheel rim.

Description

Fahrrad mit Hilfsmotor insbesondere Elektròmotor. Bicycle with an auxiliary motor, in particular an electric motor.

Es ist schon oft versucht worden, ein Fahrrad mit Hilfsmotor zu bauen. Entweder-scheiterten die Versuche daran, daß die Kupplung den Leerlauf zu sehr erschwerte, oder daß man eine Reibrolle benutzte, die dann bei Steigungen rutschte und die Lauffläche zerstörte.-Es wurde auch schon vorgeschlagen, das Rad von der Seite auf die Felge anzutreiben, was das Rad natürlich viel zu sehr einseitig belasten würde.Many attempts have been made to build a bicycle with an auxiliary motor. The attempts either-failed because the clutch made idling too difficult, or that you used a friction roller, which then slipped on inclines and the tread destroyed.-It has also been suggested to move the wheel from the side onto the rim to drive, which of course would put too much strain on the bike.

Zweck dieser Erfindung ist ed, die Kupplung derart zu gestalten, daß das Rad im Leerlauf wie bei eingeschaltetem Motor ohne Rei= bungsverlust bei einfachster Bedienung betrieben werden kann, was bei Verwendung von Elektromotoren wegen der geringen Kraft= reserve besonders wichtig ist. Erfindungsgemäß wird folgendes vorgeschlagen: Das vom Motor angetriebene Zahn- oder Riemenrad auf der Radnabe erhält ebenso einen Freilauf wie das vom den Pedalen angetriebene Zahnrad; oder es wird an oder unter der Felge, an den Speichen oder auf der Radnabe ein Zahnkranz angebracht, auf den, aus der Sicht des angetriebenen Rades, radial oder axial, aber unmittei bar ohne Kette oder Riemen, das Zahnrad eines Motors wirkt, der an einem Zapfen drehbar gelagert ist, oder dessen Zahnrad magne= tisch oder mechanisch eingekuppelt wird, und bei axial-Antrieb, inshesondere auf die Felge, auf der anderen Seite eine Druckaus= gleichrolle mitbetätigt weden kann. Der Antrieb kann sowohl am Vorder- wie am Hinterrad erfolgen.The purpose of this invention is ed to make the coupling such that the wheel in idle as with the engine switched on without loss of friction with the simplest Operation can be operated, which is because of the use of electric motors low power = reserve is particularly important. According to the invention, the following is proposed: The motor-driven toothed or belt wheel on the wheel hub also receives one Freewheel like the gear driven by the pedals; or it will be at or under a ring gear attached to the rim, to the spokes or to the wheel hub on which, from the point of view of the driven wheel, radially or axially, but without bar without Chain or belt, the gearwheel of a motor acts, which is rotatably mounted on a pin is, or its gear is magnetically or mechanically engaged, and at axial drive, especially on the rim, on the other side a pressure output = the same role can also be actuated. The drive can be on the front as well as on the rear wheel take place.
