Abstract
Betätigungseinrichtung für die Mehrgang-Getriebenabe eines Fahrrades mit interner Rasterung umfassend ein Gehäuse (1), ein zum Schalten zu drehendes Abtriebselement (2) und zwei Zugseile (4a,b), dadurch gekennzeichnet, daß die Betätigungseinrichtung mit voneinander unabhängigen Schaltelementen (5a,b) so ausgestattet ist, daß für einen Schaltvorgang nur eins der beiden Zugseile (4a,b) durch Ziehen betätigt werden muß, das jeweils andere Seil wird nicht bewegt.Actuating device for the multi-speed gear hub of a bicycle with internal grid, comprising a housing (1), an output element (2) to be rotated for shifting and two pull cables (4a, b), characterized in that the actuating device has independent switching elements (5a, b ) is equipped in such a way that only one of the two pull cables (4a, b) has to be actuated by pulling for a switching process, the other cable is not moved.
Description
Stand der TechnikState of the art
Moderne Fahrräder sind in der Regel mit mehreren Gängen ausgestattet. Eine Möglichkeit, dies zu erreichen, ist die Verwendung einer Mehrgang-Getriebenabe, meist einfach als Getriebenabe bezeichnet.Modern bicycles are usually equipped with multiple gears. One way to achieve this is to use a multi-speed gear hub, usually simply referred to as a gear hub.
Diese Getriebenaben werden in der Regel durch lenkermontierte Schalter betätigt. Zur Übertragung dienen Zugseile (Schaltzüge). Um die unterschiedlichen Gangstufen definiert einrasten zu lassen, muß eine Rasterung entweder im Schalter oder in der Getriebenabe selbst vorhanden sein.These gear hubs are typically operated by handlebar-mounted switches. Pull cables (shift cables) are used for transmission. In order to allow the different gear levels to engage in a defined manner, there must be a grid either in the switch or in the gear hub itself.
Eine Getriebenabe mit Rasterung in der Getriebenabe zeigt
AufgabenstellungTask
Der Erfindung liegt die Aufgabe zugrunde, eine Mehrgang-Getriebenabe mit Rasterung in der Getriebenabe so anzusteuern, daß von den beiden Schaltseilen immer nur das benötigte betätigt werden muß. Hiermit wird die Seilreibung deutlich vermindert. Auch können dadurch übliche Fahrradschalter, die nur ein einziges Seil einziehen und freigeben können, verwendet werden, indem man von diesen zwei verwendet. Das kann zum Beispiel sinnvoll sein, wenn man eine Rohloff-Nabe an einem Fahrrad mit Rennlenker verwenden möchte, denn der originale Rohloff-Schalter paßt nicht ohne weiteres an einen Rennlenker.The invention is based on the object of controlling a multi-speed transmission hub with a grid in the transmission hub in such a way that only the required part of the two shift cables always has to be actuated. This significantly reduces rope friction. This also means that common bicycle switches that can only retract and release a single cable can be used by using two of them. This can be useful, for example, if you want to use a Rohloff hub on a bicycle with racing handlebars, because the original Rohloff switch does not easily fit on a racing handlebar.
LösungSolution
Die Aufgabe wird durch die Merkmale der unabhängigen Ansprüche 1 und 7 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen gekennzeichnet. Die Lösung des Problems liegt in einer speziellen Betätigungseinrichtung (Seilbox) für die Rohloff-Nabe mit externer Zugführung. Die Seilbox ist die Schnittstelle zwischen den beiden Schaltseilen und der Nabe.The task is solved by the features of independent claims 1 and 7. Advantageous refinements are characterized in the subclaims. The solution to the problem lies in a special actuation device (cable box) for the Rohloff hub with external cable guidance. The cable box is the interface between the two shift cables and the hub.
