Abstract
Description
Am Fahrrad wird die Lichtmaschine (Dynamo) herkömmlicher weise durch ein Reibrad angetrieben, das auf der Reifenflanke läuft. Dieses neigt aber besonders in Gegenwart von Nässe, Schnee oder Schmutz zum Durchrutschen, so daß die Beleuchtung nur schwach leuchtet, flackert oder ganz ausfällt. In der dunklen Jahreszeit sind immer wieder schwere und tödliche Unfälle darauf zurückzuführen, daß wegen dieses Versagens nicht beleuchtete Fahrräder von Autofahrern übersehen werden.On the bike, the alternator (dynamo) is becoming more conventional wise driven by a friction wheel on the side of the tire running. But this tends especially in the presence of moisture, Snow or dirt to slip through, so the lighting only dimly shines, flickers or fails completely. In the dark seasons are always heavy and deadly Accidents due to the fact that this failure motorcycles that are not illuminated are overlooked by motorists.
Zwar ist die Reifenflanke üblicherweise geriffelt und auch das Reibrad der Lichtmaschine mit einem Rändel versehen. Diese Rändel sind jedoch ziemlich fein und auch von verschie dener Teilung, so daß nicht von einem Formschluß gesprochen werden kann. Kommt das Reibrad nun einmal durch Nässe, Schnee oder Schmutz zum Gleiten, so nutzen sich die Spitzen des Rändels am Reibrad sehr schnell ab und werden glatt, so daß es seine Funktion verliert und fortan noch mehr zum Durch rutschen neigt. Das Reibrad muß dann erneuert werden.The tire flank is usually corrugated and also knurled the alternator friction wheel. However, these knurls are quite fine and also different their division, so that it is not spoken of a form fit can be. If the friction wheel comes through wet, snow or dirt to slide on, so the tips of the Knurls on the friction wheel very quickly and become smooth, so that it loses its function and henceforth even more to go through tends to slip. The friction wheel must then be replaced.
Bekannt sind ferner auf das Reibrad aufsteckbare Kappen aus Gummi oder Kunststoff. Da der Reibwert zwischen Gummi und Gummi höher ist als zwischen Stahl und Gummi, bewirken sie einen besseren Antrieb, solange die Reibflächen trocken sind. Bildet sich jedoch ein wäßriger Schmierfilm zwischen Reifen und Kappe, gleitet das so bestückte Reibrad ebenso wie ein stählernes und nützt sich noch schneller ab als dieses.Caps are also known to be attachable to the friction wheel Rubber or plastic. Because the coefficient of friction between rubber and Rubber is higher than between steel and rubber, they cause a better drive as long as the friction surfaces are dry. However, an aqueous film of lubricant forms between tires and cap, the friction wheel thus equipped slides in as well steel and wears out even faster than this.
Um die vorgenannten Nachteile zu überwinden, lehrt die vor liegende Erfindung, die Lichtmaschine formschlüssig anzutrei ben, indem die Reifenflanke mit einer Verzahnung versehen wird, beispielsweise dergestalt, wie sie bei Synchronriemen (Zahnriemen) verwendet wird, und das Antriebsrad der Licht maschine dazu passend als Synchronscheibe (Zahnrad) ausgebil det wird (Fig. 1).In order to overcome the aforementioned disadvantages, the present invention teaches ben to positively drive the alternator by providing the tire flank with a toothing, for example such as is used in synchronous belts (toothed belts), and the drive wheel of the alternator to match Synchronizer disc (gear) is ausgebil det ( Fig. 1).
Um das Reibrad nicht demontieren zu müssen, kann ferner die Verzahnung des Antriebsrades auch als eine Kappe aus z.B. Gummi oder Kunststoff ausgebildet werden, die auf das vor handene Reihrad aufgesteckt werden kann (Fig. 2). In order not to have to dismantle the friction wheel, the toothing of the drive wheel can also be designed as a cap made of, for example, rubber or plastic, which can be plugged onto the existing wheel ( Fig. 2).
Als Nachteil des vorgenannten Antriebes kann angesehen wer den, daß es erforderlich ist, nicht nur ein neues Antriebsrad, sondern auch einen neuen Reifen anzuschaffen. Will man aber eine zuverlässige Mitnahme erzielen, ohne den herkömmlichen Reifen zu erneuern, so kann ein Formschluß dadurch erzeugt werden, daß als Reibrad eine kunststoffgebundene Drahtbürste eingesetzt wird (Fig. 3). Die Drahtspitzen sind in der Lage, einen etwa vorhandenen Schmierfilm zu durchdringen und sich mit dem Reifengummi zu verkrallen, während die Kunststoffbin dung dafür sorgt, daß die Spitzen nicht umbiegen. Selbst wenn die Bürste zum Gleiten kommt, nutzt sich die Kunststoffbin dung stärker ab als der Draht, so daß sich die Bürste selbst nachschärft.As a disadvantage of the aforementioned drive, who can be seen that it is necessary to purchase not only a new drive wheel, but also a new tire. But if you want to achieve a reliable take-along without replacing the conventional tire, a positive connection can be generated by using a plastic-bonded wire brush as the friction wheel ( Fig. 3). The wire tips are able to penetrate an existing lubricating film and claw with the tire rubber, while the plastic binding ensures that the tips do not bend. Even if the brush slides, the plastic binding wears out more than the wire, so that the brush resharpenes itself.
