Description

Patenτ-Ansprüche:Patent claims:

1. Reibungskupplung, dadurch gekennzeichnet, dafs das äufsere Ende einer Schneckenfeder an dem treibenden Theil angeschlossen ist und das innere Ende den getriebenen Theil umgiebt, so dafs letzterer infolge Aufwickelung der Schneckenfeder und Festklemmens um ihn mitgenommen wird.1. Friction clutch, characterized in that the outer end of a helical spring is dafs is attached to the driving part, and the inner end surrounds the driven part, so that the latter as a result Winding up the helical spring and clamping around it is taken along.

2. Eine Ausführungsform der Kupplung nach Anspruch 1, gekennzeichnet durch Walzen g, die zwischen die Windungen der Schneckenfeder gelegt sind.2. An embodiment of the coupling according to claim 1, characterized by rollers g which are placed between the turns of the helical spring.

3. Eine Kupplung nach Anspruch 1 oder 2, bei der das äufsere Ende c der Schneckenfeder mit einem Zwischengliede d in Verbindung steht, dessen Zunge f beim Kuppeln die Windungen der Feder gegen die Welle α drückt.3. A coupling according to claim 1 or 2, in which the outer end c of the helical spring is connected to an intermediate member d , the tongue f of which presses the turns of the spring against the shaft α during coupling.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die den Gegenstand der Erfindung bildende selbstschliefsende Federkupplung besteht aus einem dünnen federnden Band aus Stahl oder anderem Metall, welches mit seinem einen Ende an den treibenden Theil angeschlossen ist und mit dem anderen die zu treibende Welle umwickelt; oder umgekehrt für den Fall, wo die Welle als treibender Theil auftritt. The self-closing spring clutch forming the subject of the invention consists of a thin elastic band made of steel or other metal, which with its one The end is connected to the driving part and with the other the part to be driven Shaft wrapped; or vice versa in the case where the wave appears as the driving part. Das Band ist in Form einer Spiralfeder auf der Welle um sich selbst herumgewickelt. Bei der Vorwärtsbewegung des treibenden Theiles wird daher das Band, sich auf die Welle aufwickelnd, diese umklammern und so in Drehung versetzen. Dagegen hört die durch diese Umwickelung bewirkte Kupplung auf, wenn der treibende Theil in Stillstand geräth, indem dann die Welle das Band gewissermafsen abwickelt und so in ihrer Bewegung frei wird.The ribbon is wrapped around itself in the form of a spiral spring on the shaft. at the forward movement of the driving part will therefore cause the tape to wind up on the shaft, Clasp them and turn them. On the other hand, she hears through this wrapping caused clutch when the driving part comes to a standstill by then the wave unwinds the tape to a certain extent and is thus free in its movement. In Fig. ι und 2 sind zwei Ausführungsformen einer solchen Kupplung im Schnitt dargestellt. Die Welle ist in beiden Figuren mit a, das Kuppelband mit b bezeichnet. Das Ende c des letzteren wird entweder unmittelbar an den treibenden Theil angeschlossen oder an ein Zwischenstück d, welches bei e an dem treibenden Theil befestigt ist, so dafs bei einer Vorwärtsbewegung des letzteren das Band veranlafst wird, sich an die Welle anzuschliefsen, unterstützt von der Zunge f des Zwischengliedes, welche einen Druck auf die Welle ausübt.In Fig. Ι and 2 two embodiments of such a coupling are shown in section. The shaft is denoted by a in both figures and the coupling belt by b. The end c of the latter is either connected directly to the driving part or to an intermediate piece d, which is fastened to the driving part at e , so that when the latter moves forward, the band is caused to join the shaft, supported by the Tongue f of the intermediate member, which exerts pressure on the shaft. Bei der in Fig. 2 dargestellten Ausführungsform sind Walzen g zwischen die Windungen der Spiralfeder oder des Bandes eingeschaltet. Während die erste dieser Walzen durch einen seitlichen Vorsprung h des Bandes an Ort und Stelle erhalten wird, dienen Abstandblöcke i zur Erhaltung der anderen Walzen in den geeigneten Entfernungen von einander.In the embodiment shown in Fig. 2, rollers g are switched between the turns of the spiral spring or the belt. While the first of these rollers is held in place by a lateral projection h of the belt, spacer blocks i serve to maintain the other rollers at the appropriate distances from one another. Erforderlichen Falles kann man das Federband mit Leder bekleiden.If necessary, the spring band can be covered with leather. Diese Kupplungen finden namentlich bei Fahrrädern und bei Motorwagen Anwendung, um hier die Bewegung nur nach einer Richtung hin zu übertragen, so dafs z. B. die Tretkurbeln gewünschten Falles angehalten werden können.These clutches are used in particular on bicycles and motor vehicles, in order to transmit the movement here only in one direction, so that z. B. the cranks can be stopped if desired.
