Description

Antrieb von Kleindynamos durch eine unter Federwirkung stehende, von der Fliehkraft beeinflußte Reibungskupplung. Es sind Antriebe von Kleindynamos bekannt, die durch eine Reibungskupplung gebildet werden, welche von der Fliehkraft eines unter Federwirkung stehenden Organs hemmend beeinflußt wird.Small dynamos are driven by a spring-loaded from the centrifugal force influenced friction clutch. Drives for small dynamos are known, which are formed by a friction clutch, which is driven by the centrifugal force of a under spring action organ is inhibited.

Diese vielfach vielteiligen Antriebe sind ziemlich unzuverlässig, da durch die z. B. beim Fahren eines Rades bedingten Erschütterungen der Lichtmaschine leicht Störungen in derselben auftreten, durch welche die Beleuchtung außer Betrieb gesetzt werden kann.These multi-part drives are quite unreliable, because the z. B. when driving a bike caused vibrations of the alternator Disturbances easily occur in the same, as a result of which the lighting is out of order can be set.

Das Wesen der Erfindung besteht darin, daß die zwei unmittelbar auf der Drehachse sitzenden Backen der Reibungskupplung durch eine einzige Blattfeder an die Achse angedrückt werden, welche den äußeren Umfang der Backen umspannen.The essence of the invention is that the two immediately the axis of rotation seated jaws of the friction clutch by a single leaf spring be pressed against the axis, which span the outer circumference of the jaws.

Die Zeichnung zeigt ein Ausführungsbeispiel einer solchen Antriebsvorrichtung in Abb. i in Ansicht und in Abb. 2 im Querschnitt. Abb. 3 stellt die mit der Antriebsvorrichtung versehene Dynamo in Ansicht dar.The drawing shows an embodiment one such a drive device in Fig. i in view and in Fig. 2 in cross section. Fig. 3 shows the dynamo provided with the drive device in a view.

Auf der Ankerwelle a sitzt eine aus zwei Backen b bestehende Klemmbüchse, welche mit Hilfe von federnden Ringen c auf die Welle a gepreßt wird. An ,Stelle der Ringe könnte auch eine Blattfeder angeordnet sein. Die Klemmbüchse b ist mit Zapfen d versehen, welche in Aussparungen der Antriebsscheibe e greifen, die über die Büchse b gesteckt ist und lose auf der Welle a sitzt. Die Antriebsscheibe e nimmt also die Klemmbüchse b mit Hilfe ihrer Zapfen d mit.A clamping sleeve consisting of two jaws b sits on the armature shaft a and is pressed onto the shaft a with the aid of resilient rings c. Instead of the rings, a leaf spring could also be arranged. The clamping sleeve b is provided with pins d which engage in recesses in the drive pulley e, which is inserted over the sleeve b and sits loosely on the shaft a. The drive pulley e thus takes the clamping sleeve b with the help of its pin d .

Die Wirkungsweise dieser Vorrichtung ist folgende: Infolge der .Spannung der Federn c wird die Klemmbüchse b an die Welle a gedrückt und damit diese durch die Antriebsscheibe e mitgenommen, die in bekannter Weise von einem der Räder des Fahrrades angetrieben wird. Die Federspannung ist dabei derart eingestellt, daß bis zu der zur Stromerzeugung notwendigen Drehzahl die Welle at mitgenommen wird. Bei Überschreitung dieser bestimmten Drehzahl überwindet die Fliehkraft der Klemmbüchse b die Spannung der Federn c, so daß die Büchse b auf der Welle o schleift. Infolgedessen wird eine schädigende Steigerung der Stromspannung vermieden und damit die eingangs erwähnten Nachteile beseitigt. Da die Klemmbüchse b durch gleitende Reibung die Antriebswelle - a trotzdem noch mitnimmt, wird ein Erlöschen der Lampe verhindert.The mode of operation of this device is as follows: As a result of the tension of the springs c, the clamping sleeve b is pressed against the shaft a and thus it is carried along by the drive pulley e, which is driven in a known manner by one of the wheels of the bicycle. The spring tension is set in such a way that the shaft at is taken along up to the speed required to generate electricity. When this specific speed is exceeded, the centrifugal force of the clamping sleeve b overcomes the tension of the springs c, so that the sleeve b grinds on the shaft o. As a result, a damaging increase in the voltage is avoided and the disadvantages mentioned at the beginning are eliminated. Since the clamping sleeve b still carries the drive shaft - a with it due to sliding friction, the lamp is prevented from going out.
