Description
<Desc/Clms Page number 1>
Einrichtung zur Befestigung eines Hilfsmotors am Rahmen eines Fahrrades.
Die Befestigung von Fahrrad-Hilfsmotoren unterhalb des Rahmens eines Fahrrades an dem schräg hochlaufenden Rahmenrohr ist bekannt. Ausser der einseitigen Beanspruchung des Rahmens besteht hiebei die Möglichkeit, dass sich der Motor durch den Riemenbzw. Kettenzug um die Achse des Befestigungsrohres verdreht. Um sowohl diese Verdrehung zu vermeiden, als auch das Motorgehäuse zur Verstärkung des Rahmens zu benutzen, ist dasselbe gemäss der Erfindung unter dem Tretlager hindurch verlängert und diese Verlängerung mit der Hinterradgabel verschraubt.
Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführungsform schematisch veranschaulicht.
Das Motorgehäuse a trägt eine Verlängerung b, die unterhalb des Tretkurbellagers c verläuft. Das hintere Ende dieser Verlängerung b ist an der Hinterradgabel d mittels Verschraubung e befestigt. Ausserdem ist das Motorgehäuse a an dem schräg nach vorwärts verlaufenden Rahmenrohr, t'durch eine Schraubenverbindung g aufgehängt.

Device for attaching an auxiliary engine to the frame of a bicycle.
The attachment of bicycle auxiliary motors below the frame of a bicycle on the sloping frame tube is known. In addition to the one-sided stress on the frame, there is the possibility that the motor may be damaged by the belt or Chain hoist twisted around the axis of the fastening tube. In order both to avoid this twisting and to use the motor housing to reinforce the frame, the same is extended under the bottom bracket according to the invention and this extension is screwed to the rear fork.
The subject matter of the invention is illustrated schematically in the drawing in one embodiment.
The motor housing a carries an extension b which runs below the pedal crank bearing c. The rear end of this extension b is attached to the rear fork d by means of a screw connection e. In addition, the motor housing a is suspended from the frame tube t ′, which runs obliquely forwards, by a screw connection g.
