Abstract

The bicycle has a pedal (1) with two pedal drives (2) for each housing and a ring-shaped shaft (8) fixed to the unit. Each shaft has a section (4) with a joint (5) in the middle of the working unit and a transfer medium (30). At least one pedal drive has a coupling (9) and there is a frame for many pedals. The force transfer via the shaft has a single section and a transmission band (3). The wheels of the unit are hydraulically linked.

Description

BeschreibungDescription

Antrieb für ein ringförmiges Fahrrad für mehrere FahrerDrive for a ring-shaped bicycle for several riders

Es wird eine Antriebsvariante eines Mehrpersonenfahrrades vorgestellt. Bei diesem Mehrpersonenrad mit kreisförmiger Anordnung der Fahrer tritt das Problem auf, daß die Antriebskräfte nicht in einer Ebene, sondern verdrillt oder versetzt übertragen werden müssen. Die Fahrer sitzen hier kreisförmig und sehen auf einen Mittelpunkt. Dadurch sind die Fahrer und damit die Tretlagerachsen winkelversetzt. Die Tretkräfte werden bevorzugt von einer ringförmigen Welle übertragen, deren Teilstücke mit Kardangelenken verbunden sind. Die einzelen Tretlagerachsen sind mit dieser Ringwelle mittels Winkelgetrieben verbunden.A drive variant of a multi-person bicycle is presented. With this multi-person bicycle with a circular arrangement of riders, the problem arises that the drive forces must not be transmitted in one plane, but twisted or offset. The riders sit in a circle and look at a center. This means that the riders and thus the bottom bracket axes are offset at an angle. The pedal forces are preferably transmitted by a ring-shaped shaft, the sections of which are connected with universal joints. The individual bottom bracket axes are connected to this ring shaft by means of angle gears.

Bei diesem Lösungsvorschlag wird ebenfalls eine bevorzugt ringförmige Welle verwendet, die durch Kardangelenke in sich drehbar ist. Diese wird bevorzugt von allen, ebenfalls kreisförmig angeordneten, Tretlagern unmittelbar oder über eine Antriebskette angetrieben.This proposed solution also uses a preferably ring-shaped shaft that can rotate using cardan joints. This is preferably driven by all bottom brackets, which are also arranged in a circle, either directly or via a drive chain.

Diese Arbeitsverbindung zwischen den einzelnen Tretlagern und dem davon angetriebenen Teilstück der Ringwelle ist dadurch gekennzeichnet, dass sie mittels einer Überholkupplung verläuft.This working connection between the individual bottom brackets and the part of the ring shaft driven by them is characterized by the fact that it runs by means of an overrunning clutch.

In dem bevorzugten Ausfuhrungsbeispiel treibt je ein Tretlager über ein Ritzel eine Antriebskette an, die ein Ritzel auf der Ringwelle antreibt. Zwischen dem Ritzel auf der Ringwelle und der Ringwelle befindet sich eine Überholkupplung (Freilauf).
Dadurch kann sich jeder einzelne Fahrer unabhängig von den anderen Fahrern an der Kraftübertragung beteiligen oder er kann diese jederzeit unterbrechen.
Kennzeichnend ist, dass sich zwischen dieser Welle und den Pedalen eine Überholkupplung befindet, so dass sich jeder Fahrer unabhängig von den anderen Fahrern an der Kraftübertragung beteiligen oder diese unterbrechen kann.In the preferred embodiment, each bottom bracket drives a drive chain via a pinion, which drives a pinion on the ring shaft. There is an overrunning clutch (freewheel) between the pinion on the ring shaft and the ring shaft.
This allows each individual driver to participate in the power transmission independently of the other drivers or to interrupt it at any time.
A characteristic feature is that there is an overrunning clutch between this shaft and the pedals, so that each driver can participate in or interrupt the power transmission independently of the other drivers.
