Abstract

The crank (1) consists of an axle (2) and at least one crank body (3) on the end of the axle. The crank body has an outer surface (4) for accommodating one or more bearing rings in its inner region coaxial to the rotation axis. The bearing is supported by the other, non-rotating ring (6) via the pedal bearing housing (7) so the axle is free to rotate within the housing.

Description

Es ist bekannt das die Lagerung der herkömmlichen Fahrradkurbeln durch die Abstützung des Lagers auf die Achse erfolgt. Dabei entsteht unter anderem die Beanspruchung der Welle auf die Biegung, was die negative Auswirkung auf das Rollverhalten und die Gebrauchsdauer des Lagers hat.It is known that the storage of conventional bicycle cranks through the support of the Bearings on the axis is done. Among other things, the stress arises the wave on the bend, what the negative impact on the roll behavior and the service life of the bearing has.

Die in Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde die auf die Welle und den Lager auftretenden Belastungen zu reduzieren.The specified in claim 1 invention, the problem is based to reduce the loads on the shaft and the bearing.

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This Problem is solved by the features listed in claim 1 solved.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass mit der Anordnung des Lagersitzes im Kurbelkörper vergrößert sich die gesamte Abstützbreite der Lagerung, was zur Reduzierung der Biege und Scherbelastungen auf die Achse, aber auch zum verbesserten Rollverhalten des Lagers führt.The particular advantages of the invention are that increases with the arrangement of the bearing seat in the crank body the entire support width storage, resulting in reduction of bending and shear loads on the axle, but also for improved rolling behavior of the bearing leads.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Patentanspruch 2 angegeben. Die Weiterbildung nach Patentanspruch 2 ermöglicht es die beiden Kurbeln mittels eine Hülse in der Mitte von Achse zu verbinden. Die Verbindungshülse wirkt dabei verstärkend auf die Achse bei der Übertragung von Drehmomenten.A advantageous embodiment of the invention is in claim 2 specified. The development according to claim 2 makes it possible the two cranks by means of a sleeve in the middle of axis connect to. The connection sleeve thereby reinforcing to the axis in the transmission of Torques.

Die weitere Ausgestaltung der Erfindung nach dem Merkmal aus dem Patentanspruch 3 bietet vorteilhafte Möglichkeit die Kurbel mit der Achse am Stück aus leichten Metallen oder Stoffen, wie zum Beispiel Karbon, herzustellen.The further embodiment of the invention according to the feature of the claim 3 offers advantageous possibility the crank with the axle in one piece made of light metals or materials such as carbon.
