Description

Vorrichtung zur Regelung des Anpreßdruckes des Antriebsrades einer elektrischen Lichtmaschine für Fahr- und Motorräder Bei den bisher bekannten Konstruktionen von elektrischen Lichtmaschinen für Fahr-und Motorräder, vornehmlich bei Ausführungen, bei denen ,die Andruckfeder in der Halteachse der Lichtmaschine eingebaut ist, genügt der Anpreßdruck nicht, um bei abgelaufenen, verschmierten und vereisten, Rillen des Antriebsrades dieses so stark gegen ,den Laufmantel zu drücken, daß dasselbe immer in Drehung bleibt.- Die Folge davon ist, daß gerade in kälteren Jahreszeiten, wenn. die Beleuchtung .der Fahrzeuge am meisten gebraucht wird, von der Lichtmaschine kein elektrischer Strom erzeugt wird, sondern zur Speisu4g der Glühbirne .des Scheinwerfers usw. eine elektrische B.ätterie verwandt werden muß. Zur Abwendung dieses Übelstandes ist gemäß der Erfindung zwischen einem Arm der Befestigungsschelle für den Lichtmasrhinenhalter und :einem an. :der Lichtmaschine befestigten Widerlager .eine zusätzliche, aus Sichraubenspindel und Flügelmutter bestehende Anpreßvorrichtung zeit einer Druckfeder zwischen der Flügelmutter und dem WidIerla,ger angeardnet. Durch diese Vorrichtung, die zusätzlich an jede Lichtmaschine eines Fahr- und Motorrades angebaut werden kann,, wird erreicht, @daß der ,Ampreß-druck des Antriebsrades beliebig stark eingestellt werden kann, somit ein Gleiten des Antriebsrades in jedem Fall vermieden wird und ein einwandfreier Betrieb der Lichtmaschine gewährleistet ist. Die Erfindung ist auf :der Zeichnung beisp@el!sweise in einer Ausführungsform dargestellt, und zwar zeigt Abb. i die angebrachte Vorrichtung an einer elektrischen Lichtmaschine von. der Seite ;gesehen, Abb.2 die angebrachte Vorrichtung an einer elektrischen Lichtmaschine von vorn gesehen, Abb.3 den Lichtmaschinenhalter mit Befestigungsschelle von der Seite gesehen, Abb. q. den Lichtmaschinenhalter mit Befestigungsschelle von oben gesehen, Abb.5 eine Ansicht der Lichtmaschinenmanschette mit Widerlager, Abb.6 die Lichtmaschinenmanschette mit Widerlager von oben gesehen.Device for regulating the contact pressure of the drive wheel a electric alternator for bicycles and motorcycles In the previously known constructions of electric alternators for bicycles and motorcycles, primarily for designs where the pressure spring is installed in the holding shaft of the alternator is sufficient the contact pressure is not in order to cope with worn, smeared and icy grooves of the drive wheel this so strongly against to press the barrel jacket that the same thing always keeps turning.- The consequence of this is that especially in colder seasons, if. the lighting of the vehicles is most needed from the alternator no electrical current is generated, but to feed the light bulb of the headlight etc. an electric B.ätterie must be used. To avert this disadvantage is according to the invention between an arm of the mounting bracket for the Lichtmasrhinenhalter and: one on. : the alternator attached abutment. an additional, off Self-locking spindle and wing nut existing pressing device time of a compression spring between the wing nut and the WidIerla, ger angeardnet. Through this device, which are also attached to every alternator of a motorbike or motorcycle can ,, it is achieved @ that the, amperage pressure of the drive wheel is set as high as desired can be so that a sliding of the drive wheel is avoided in any case and perfect operation of the alternator is guaranteed. the The invention is shown on: the drawing, for example, in one embodiment, namely Fig. i shows the device attached to an electric alternator from. the side; seen Fig.2 the attached device to an electrical The alternator seen from the front, Fig. 3, the alternator holder with mounting bracket seen from the side, fig.q. the alternator holder with mounting bracket seen from above, Fig.5 a view of the alternator sleeve with abutment, Fig.6 the alternator sleeve with abutment seen from above.

Der Lichtmaschinenhalter ist nach bekann: ter Art mit einer Schelle i o versehen, die mittels der beiden Schrauben 12 an der Gabel des Fahr oder Motorrades angeschraubt wird. Rechtwinklig nach oben ist ein Arm 7 mit Langloch 8 zur Anbringung der Lichtmaschine vorgesehen. Der Arm 9, der die Verlängerung der Schelle i o bildet und ebenfalls mit einem Langloch i i versehen ist, dient zur Befestigung ,der Schraubenspindel 16 mittels der beiden Muttern 13, 14. Über die Schraubenspindel 16 wird die Druckfeder 18 ;gestreift, die durch die Flügelmutter 15, welche sich auf dem Gewinde 17 befindet, gespannt werden kann.. Eine Verlängerung 5 der Manschette i, -die, um sich den verschiedenen Größen der Lichtmaschinen, anzupassen, schellenartig ausgebildet ist, dient als Widerlager für die Druckfeder 18. Die Manschette i wird über die Lichtmaschine gestreift und mittels der durch die beiden Löcher 3 hindurchgesteckten Schraube 2 fest. gekleihmt. Damit die Halteachse der Lichtmaschine nicht hinderlich ist, ist die Manschette i mit der Aussparung q. versehen,. Außerdem weist die Verlängerung 5 der Manschette ein Langloch 6 auf, durch das der Federbolzen 16 hindurchreicht.The alternator holder is well known with a clamp i o provided by means of the two screws 12 on the fork of the bike or motorcycle is screwed on. At right angles upwards is an arm 7 with an elongated hole 8 for attachment the alternator provided. The arm 9, which forms the extension of the clamp i o and is also provided with an elongated hole i i, is used for fastening, the screw spindle 16 by means of the two nuts 13, 14. About the screw spindle 16, the compression spring 18; striped, through the wing nut 15, which is located on the thread 17, Can be stretched .. An extension 5 of the cuff i, -that to accommodate the various Sizes of the alternators, adjust, is designed like a clamp, serves as Abutment for the compression spring 18. The sleeve i is slipped over the alternator and by means of the screw 2 inserted through the two holes 3. clad. So that the holding axis of the alternator is not a hindrance, the sleeve is i with the recess q. Mistake,. In addition, the extension 5 has the cuff an elongated hole 6 through which the spring bolt 16 extends.

Die Wirkung der Vorrichtung ist die, daß die Druckfeder 18 über die Flügelmutter 15 und Schraubenspindel 16 gegen den, Arm 9 des Lichtmaschinenhalters einerseits und gegen das Widerlager 5 andererseits drückt. Dieser Druck, der :durch Verstellen der Flügelmutter 15 eingestellt werden kann, verstärkt den Druck der vorhandenen Feder so, daß der Anpreßdruck des Antriebsrades gegen den Laufmantel jeweils so groß ist, daß zu jeder Zeit ein einwandfreier Betrieb der Lichtmaschine gewährleistet ist.The effect of the device is that the compression spring 18 presses via the wing nut 15 and screw spindle 16 against the arm 9 of the alternator holder on the one hand and against the abutment 5 on the other hand. This pressure, which: can be adjusted by adjusting the wing nut 1 5 , increases the pressure of the existing spring so that the contact pressure of the drive wheel against the barrel jacket is so great that perfect operation of the alternator is guaranteed at all times.
