Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Welle.Wave.

Die Erfindung bezieht sich auf einen Kegelradantrieb für solche Fahrräder, bei welchen die zwischen der Tretkurbel- und Hinterradachse eingeschaltete Kraftübertragungswelle getheilt ist und die beiden Wellentheile durch eine Klauenkupplung mit einander verbunden werden, wie u. A. in der amerikanischen Patentschrift Nr. 560647 beschrieben ist. Während bei dem in letzterer beschriebenen Antriebe die Kupplungstheile selbst als Centrirvorrichtung für die Theile der Uebertragungswelle ausgebildet sind, wird die Centrirung nach vorliegender Erfindung durch einen von den in einander greifenden Kupplungstheilen unabhängig angeordneten Kugelzapfen in der Mitte der Kupplung bewerkstelligt und dadurch der Vortheil erzielt, dafs die Centrirvorrichtung von der mit der Zeit unvermeidlich eintretenden Abnutzung der Kupplungsflächen unbeeinflufst bleibt.The invention relates to a bevel gear drive for such bicycles, in which the power transmission shaft connected between the crank axle and the rear wheel axle is divided and the two parts of the shaft are connected to each other by a claw coupling as described, inter alia, in American Patent No. 560647. While in the case of the drives described in the latter, the coupling parts themselves act as centrifugal devices are designed for the parts of the transmission wave, the centering is according to the present Invention by one of the interlocking coupling parts independent arranged ball stud accomplished in the middle of the coupling and thereby the The advantage obtained is that the centrifugal device differs from that which inevitably occurs over time Wear of the coupling surfaces remains unaffected.

In beiliegender Zeichnung zeigt Fig. 1 eine theilweise im Schnitt gezeichnete Draufsicht eines solchen Antriebes, während Fig. 2 bis 5 Einzelheiten desselben in vergröfsertem Mafsstabe veranschaulichen.In the accompanying drawing, Fig. 1 shows a partly in section drawn plan view of such a drive, while Figs. 2 to 5 Illustrate details of the same on an enlarged scale.

Der Antrieb erfolgt in üblicher Weise durch zwei Tretkurbeln α und b, von denen die Kurbel α das Kegelrad c trägt, mit welchem der auf die Kupplungsmuffe d aufgeschraubte, auf Kugeln laufende Kegeltrieb e in Eingriff steht. Die Muffe d bildet den einen Theil der Uebertragungswelle und hat an ihrem freien Ende die Form einer mit Randnuthen versehenen Scheibe f (Fig. 4 und 5), die das eine Glied der Kupplung ausmacht. Das andere Kupplungsglied g (Fig. 2 und 3) ist mit entsprechend gestalteten Klauen ausgestattet und auf das vordere Ende des Wellentheiles h aufgeschraubt. Letzterer läuft in einen mittleren Kugelzapfen i aus, welcher in eine centrale Bohrung k des Kupplungstheiles / eingreift und die Lage der beiden Wellentheile d und h unabhängig von der Klauenkupplung/g genau centrirf.The drive is carried out in the usual way by two pedal cranks α and b, of which the crank α carries the bevel gear c , with which the bevel drive e, which is screwed onto the coupling sleeve d and running on balls, is in engagement. The sleeve d forms one part of the transmission shaft and, at its free end, has the shape of a disk f provided with edge grooves (FIGS. 4 and 5), which makes up one link of the coupling. The other coupling member g (Fig. 2 and 3) is equipped with appropriately designed claws and screwed onto the front end of the shaft part h. The latter ends in a central ball pin i , which engages in a central bore k of the coupling part / and precisely centers the position of the two shaft parts d and h independently of the claw coupling / g.

Wie leicht ersichtlich ist, erleidet der Zapfen i bei seinen geringen Bewegungen innerhalb der Bohrung k so gut wie gar keine Abnutzung, so dafs die Centrirung der beiden Theile der Kraftübertragungswelle eine dauernd gute bleibt.As can be easily seen, the pin i, with its slight movements within the bore k , suffers as good as no wear, so that the centering of the two parts of the power transmission shaft remains permanently good.
