Abstract

The drive shaft (6) between the crank wheel and the rear wheel has a gear wheel (5) at the rear end to couple with one of a number of concentric gear rings (7) on the rear axle. The gear wheel is rigidly attached to the rear wheel and the shaft is located inside a protective sleeve. The length compensating element has a sleeve connected to the drive end with splined inner wall to couple to a gear wheel on the output shaft. The shaft bear wheel is brought into contact with one of the gear rings by a ratchet profile (9) on the shaft and a selector claw (10). A spring support (4) presses the shaft into mesh. USE/ADVANTAGE - The shaft drive provides a compact transmission with a simple construction suitable for bicycles and motorcycles.

Description

Diese Erfindung gilt für Fahrräder und Motorräder aller Art. Mit dem Fuß- bzw. Motorantrieb wird die Antriebswelle (6) durch die Antriebsscheibe (1) mit Verzahnung zum Drehen gebracht, und treibt das Hinterrad an.This invention applies to bicycles and motorcycles of all kinds. With the foot or motor drive, the drive shaft ( 6 ) is made to rotate by the drive disk ( 1 ) with teeth, and drives the rear wheel.

Das anzutreibende Rad hat eine Tellerscheibe (2) mit z. B. 6 Ver­ zahnungsringen (7), welche sich auf der Tellerscheibe befinden. Das Getriebe wird mit einer Abdeckung (3) geschützt.The wheel to be driven has a plate ( 2 ) with z. B. 6 Ver toothed rings ( 7 ), which are located on the plate. The gearbox is protected with a cover ( 3 ).

Die Antriebswelle (6) mit Zahnrad (5) befindet sich z. B. auf dem innersten Verzahnungsring, somit der höchste Gang. Beim Herunterschalten wird die Antriebswelle durch die Gang­ einrasterung (10) im Gehäuse (8) vom Verzahnungsring getrennt und nach außen bewegt, so kann das Zahnrad (5) auf den ge­ wünschten Zahnring. Die Gangeinrasterung (10) befindet sich nun in der Gangeinrasterungsvertiefung (9) der Antriebswelle. Eine Druckfeder (4) drückt die Antriebswelle und somit das Zahnrad (5) auf den Zahnring.The drive shaft ( 6 ) with gear ( 5 ) is located, for. B. on the innermost gear ring, thus the highest gear. When shifting down, the drive shaft is separated by the gear engagement ( 10 ) in the housing ( 8 ) from the toothing ring and moved to the outside, so the gear ( 5 ) on the desired gear ring. The gear engagement ( 10 ) is now in the gear engagement recess ( 9 ) of the drive shaft. A compression spring ( 4 ) presses the drive shaft and thus the gear ( 5 ) onto the gear ring.

Der Ausgleichsmechanismus (11), bestehend aus einer Rohrhülse mit Innenverzahnung und einer in der Rohrhülse befindenden verzahnten Welle (12), ermöglicht den Längenausgleich der Antriebswelle.The compensation mechanism ( 11 ), consisting of a tubular sleeve with internal teeth and a toothed shaft ( 12 ) located in the tubular sleeve, enables the length compensation of the drive shaft.

Claims (3)

1. Kraftübertragung vom Antrieb auf Hinterrad mit Getriebe, dadurch gekennzeichnet, daß das anzutreibende Rad durch die Antriebsscheibe mit einer Antriebswelle angetrieben wird;1. Power transmission from the drive to the rear wheel with gear, characterized in that the wheel to be driven is driven by the drive pulley with a drive shaft; 2. daß das anzutreibende Rad ein Getriebe hat, bestehend aus einer Tellerscheibe mit verschieden großen Verzahnungsringen. Die gewünschte Übersetzung erfolgt durch die Antriebswelle und dem Zahnrad, durch das Verschieben der Antriebswelle auf den vorgesehenen Zahnring;2. that the wheel to be driven has a gear consisting of a disk with toothing rings of different sizes. The desired translation is done by the drive shaft and the gear, by moving the drive shaft on the intended tooth ring; 3. daß die Antriebswelle einen Längenausgleichsmechanismus hat, bestehend aus einer Rohrhülse mit Innenverzahnung, an der, auf der einen Seite die Antriebswelle befestigt ist und einer verzahnten Welle in der Rohrhülse, die mit der unterbrochenen Antriebswelle verbunden ist.3. that the drive shaft has a length compensation mechanism, consisting of a tubular sleeve with internal teeth on which, on one side the drive shaft is attached and one toothed shaft in the tube sleeve, with the broken Drive shaft is connected.
