Description
Freilaufnabe Die Erfindung betrifft eine Freilaufnab.e für Fahrräder derjenigen bekannten Art, bei der ein mit Zähnen versehener Antriebskonus in einen glatten Hohll<onus der Nabe :eingreift. Die Erfindung besteht darin, daß die Zähne durch eine ;schraubenförmige Nut unterteilt sind, so daß sie also selbst in einer Schraubenlinie sich befinden. Dadurch wechseln bei jedem erneuten Einrücken des Antriebskonus in den Hohlkonus die Spitzen der Angriffsstellen, so daß die Oberfläche des Hohlkonus gleichmäßig beansprucht wird. Dabei wird erfindungsgemäß der Mitnehmerkonus etwas härter gemacht als der Hohlkonus, wodurch die Abnutzung in zulässigen Grenzen gehalten wird.Freewheel hub The invention relates to a freewheel hub for bicycles of the known type in which a toothed drive cone in a smooth hollow l <onus of the hub: engages. The invention is that the Teeth are divided by a; helical groove, so that they are themselves in a helix. This means that they change each time they are indented again of the drive cone in the hollow cone, the tips of the points of attack, so that the surface the hollow cone is stressed evenly. According to the invention, the driver cone is thereby Made a little harder than the hollow cone, reducing the wear within permissible limits is held.
In der Zeichnung ist als Beispiel die Ausführungsform eines derartigen Mitnehmerkonus mit Hohlkonus dargestellt, und zwar in Abb. i in Vorderansicht, teilweise geschnitten, und in Abb. 2 in Seitenansicht.In the drawing, the embodiment of such is an example Driving cone shown with hollow cone, in Fig. I in front view, partially section, and in Fig. 2 in side view.
Der Mitnehmer hat die Form einer mit zweigängigem Muttergewinde ausgestatteten Hülse i, die mit ihrem konischen Teil 2 in den Hohlkonus 3, der vollkommen glatt ist, eingreifen kann. Auf der Oberfläche- des Konus 2 sind eine große Anzahl von Zähnen q. angeordnet, die durch eine schraubenförmige Nut unterteilt sind. Durch diese Nut entstehen in eine "kleine scharfe Kante auslaufende dachförmige Zähne.The driver has the shape of one equipped with a double nut thread Sleeve i, with its conical part 2 in the hollow cone 3, which is completely smooth is able to intervene. On the surface of the cone 2 are a large number of Teeth q. arranged, which are divided by a helical groove. By this groove is created in a "small sharp edge tapering roof-shaped teeth.
Der Konus 2 wird beim Härten etwas härter gehalten als der Hohlkonus 3.The cone 2 is held somewhat harder than the hollow cone during hardening 3.
