Description

Titel: Auf nicht runden Rädern beruhende Möglichkeit zur laufenden Änderung von Übersetzungsverhältnissen.Title: Possibility of running based on non-round wheels Change of gear ratios.

Anwendungsgebiet: Die Verwendung von unrunden Rädern kann zur leichteren Überwindung von Totpunktes dienen , außerdem kann eine periodisch wiederkehrende Geschwindigkeitsänderung erzielt werden.Area of application: The use of non-round wheels can be used for easier Serve overcoming dead center, in addition, a periodically recurring Speed change can be achieved.

Erläuterung an verschiedenen Objekten: ( BeisPiele) Zu Bild 1 , Fahrrad herkömmliche Art.Explanation on various objects: (EXAMPLES) To picture 1, bicycle conventional type.

Bei Stellung 1 der Pedalarme kann die vom Fahrer auf das Pedal ausgeiibte Kraft F voll zur Wirkung kommen. Bei Pedalstellung 2 hingegen benötigt der Fahrer eine größere Kraft. um die gleiche Wirkung zu erzielen. Er hat also einen sogenannten Totpunkt zu Uberwinden.When the pedal arms are in position 1, the amount exerted by the driver on the pedal can be used Force F to be fully effective. With pedal position 2, however, the driver needs a greater force. to achieve the same effect. So he has a so-called To overcome dead center.

Zu Bild 2 Die Überwindung dieses Totpunktes kann mit Hilfe der Anordnung nach Bild 2 erleichtert werden. Bei dieser Pedalstellung , also bei größtmöglichem Antriebsmoment , bringt das unrunde Rad das größte lastmoment. Oder besser: Die Kettengeschwindigkeit ist in dieser Stell-ung gegenüber der Pedalgeschwindigkeit am größten.To picture 2 The overcoming of this dead center can be done with the help of the arrangement as shown in Figure 2. With this pedal position, i.e. with the greatest possible Drive torque, the out-of-round wheel brings the greatest load torque. Or better: The In this position, the chain speed is compared to the pedal speed the biggest.

Zu Bild 3 Bei der Stellung der Pedale nach Bild 5, also beim kleinstmöglichen Antriebamoment, bringt das unrunde Rad das kleinste Lastmoment. Oder besser: Die Kettengeschwindigkeit ist in dieser Stellung gegenüber der Pedalgeschwindigkeit am kleinsten.Re Fig. 3 With the position of the pedals according to Fig. 5, i.e. the smallest possible Drive torque, the out-of-round wheel brings the smallest load torque. Or better: The Chain speed in this position is compared to pedal speed the smallest.

Die Abstützung der Kette (Keilriemen,Zahnriemen) erfolgt ständig in einer anderen Entfernung vom Drehpunkt.The chain (V-belt, toothed belt) is constantly supported in a different distance from the pivot point.

Dadurch ändert sich laufend das Übersetzungsverhältnis.As a result, the transmission ratio changes continuously.

Die Spannung der Kette bzw. des Keilriemens oder Zahnriemens kann falls nötig durch eine Spannvorrichtung (Kettenspanner, Andruckrollen gewährleistet werden.The tension of the chain or the V-belt or toothed belt can If necessary, guaranteed by a tensioning device (chain tensioner, pressure rollers will.

Zu den Bildern 4 und 5. Anordnung zur Änderung der Geschwindigkeiten.To Figures 4 and 5. Arrangement for changing the speeds.

Die beiden Anordnungen nach Bild 4 und 5 könnten mit dem gleichen Effekt auch so betrieben werden , daß jeweils Rad antreibt.The two arrangements according to Fig. 4 and 5 could also be operated with the same effect in such a way that each wheel drives.
