Abstract

The hub dynamo is particularly suitable for two wheeled vehicles. It has a cylindrical, coaxial housing (2,4) which contains the individual components of the light machine. On one side of the housing (2,4) at the outside of a radial flange (2), a coaxial disk (6) of a disk brake is fastened to a part (2) of the light machine which rotates with the wheels. Non-rotating brake pads (8) are arranged at the side of the brake disk (6). These can be pressed in the axial direction against the brake disk (6) to apply the brake. The light machine and disk brake preferably form a single unit. The brake pads (8) may be operated hydraulically or by Bowden cables.

Description

Die Erfindung betrifft eine Nabenlichtmaschine (Dynamo), insbesondere für Zweiräder mit einem zylindrischen koaxialen Gehäuse, in dem die elektrischen Einzelteile der Lichtmaschine untergebracht sind.The invention relates to a hub alternator (dynamo), especially for two-wheelers with a cylindrical coaxial housing in which the electrical components of the Alternator are housed.

Nabenlichtmaschinen sind für Zweiräder in den unterschiedlichsten Konstruktionsarten bekannt. Sie ersetzen die üblichen Fahrraddynamos, die mit einer Reibrolle am Reifen oder an der Felge anliegen. Darüber­ hinaus ist es bekannt, Scheibenbremsen an einem Zweirad zu verwenden. Die Scheibenbremsen werden getrennt zu den übrigen Teilen der Fahrradnabe an dieser montiert.Hub alternators are for two-wheelers in the different types of construction known. she replace the usual bicycle dynamos with a Wear the friction roller against the tire or rim. About it It is also known to apply disc brakes to a two-wheeler use. The disc brakes are separated from the other parts of the bicycle hub mounted on this.

Aufgabe der Erfindung ist es, eine Nabenlichtmaschine eines Zweirades so zu verbessern, daß für die Nabenlichtmaschine und die Scheibenbremse ein geringer Herstellungs- und Montageaufwand bei geringem Gewicht und Außenabmessungen erforderlich ist. The object of the invention is a hub alternator to improve a two-wheeler so that for the Hub alternator and the disc brake a little Manufacturing and assembly costs with low weight and External dimensions are required.  

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zu einer Seite des Gehäuses an der Außenseite eines Speichenflansches eine koaxiale Scheibe einer Scheibenbremse an einem mit dem Rad umlaufenden Teil der Lichtmaschine befestigt ist, wobei an der Bremsenscheibe nicht umlaufende Bremsbacken seitlich anliegen, die in axialer Richtung gegen die Bremsenscheiben andrückbar sind.This object is achieved in that to one side of the case on the outside of one Spoke flange a coaxial disc one Disc brake on a part of the wheel rotating around the wheel Alternator is attached to the brake disc non-rotating brake shoes are on the side, which in can be pressed axially against the brake discs are.

Damit bilden Nabenlichtmaschine und Scheibenbremse eine Einheit, die zu geringen Herstellungs- und Montagekosten führt. Darüberhinaus werden die Sicherheit verbessert und Gewicht und Außenabmessungen verringert.The hub generator and disc brake thus form one Unit that has low manufacturing and assembly costs leads. In addition, security is improved and Weight and outer dimensions reduced.

Eine besonders einfache Konstruktion wird dann erreicht, wenn die Bremsenscheiben an der Außenseite eines Speichenflansches befestigt sind, der am Gehäuse der Nabenlichtmaschine fest ist. Auch wird vorzugsweise vorgeschlagen, daß die Bremsbacken hydraulisch oder durch Bowdenzug betätigbar sind.A particularly simple construction is then achieved if the brake discs on the outside of a Are attached to the housing of the Hub alternator is fixed. Also preferred suggested that the brake shoes be hydraulic or by Bowden cable can be operated.

Ein Ausführungsbeispiel ist in der Zeichnung in einer Seitenansicht dargestellt und wird im folgenden näher beschrieben.An embodiment is in the drawing in a Side view shown and will be described in more detail below described.

Die Achse 1 ist als Teil des Stators einer Lichtmaschine (Dynamo) drehfest an der Gabel eines Zweirades befestigt. Auf der Achse ist ferner eine Spule und ein Spulenkern drehfest angeordnet, so daß Achse, Spule und Spulenkern Teile des Stators der Lichtmaschine sind.Axis 1 is attached to the fork of a two-wheeler as a part of the stator of an alternator (dynamo). On the axis, a coil and a coil core is also arranged in a rotationally fixed manner, so that the axis, coil and coil core are parts of the stator of the alternator.

Auf der Achse 1 sind zwei Speichenflansche 2 drehbar gelagert, an deren äußeren Rändern Speichenlöcher 3 angebracht sind, um die Speichenenden des Rades aufzunehmen. Der Abstand zwischen den beiden Speichenflanschen 2 ist durch ein zylindrisches Mittelteil 4 überbrückt, das an den Speichenflanschen 2 befestigt, insbesondere angeformt ist und sich mit dem Rad dreht. On the axis 1 , two spoke flanges 2 are rotatably mounted, on the outer edges of which spoke holes 3 are made to accommodate the spoke ends of the wheel. The distance between the two spoke flanges 2 is bridged by a cylindrical middle part 4 , which is fastened to the spoke flanges 2 , in particular is molded on and rotates with the wheel.

Auf dem zylindrischen Innenumfang des Mittelteils 4 sind in regelmäßigen Abständen Permanentmagnete befestigt, so daß das Mittelteil 4 einen Dauermagnetrotor der Lichtmaschine bildet. Zwischen diesen Magneten und der Spule besteht ein erheblicher ringförmiger Abstand, da die Spule nur einen geringen Außendurchmesser besitzt. Dieser Abstand wird durch bandförmige, magnetisch leitende Polekörper überbrückt, die an der Spule oder dem Spulenkern befestigt sind.Permanent magnets are attached to the cylindrical inner circumference of the central part 4 at regular intervals, so that the central part 4 forms a permanent magnet rotor of the alternator. There is a considerable annular distance between these magnets and the coil, since the coil has only a small outside diameter. This distance is bridged by ribbon-shaped, magnetically conductive pole bodies, which are attached to the coil or the coil core.

An der Außenseite einer der beiden Speichenflansche 2 ist ein weiterer Flansch 5 koaxial befestigt, insbesondere angeformt, der eine kreisförmige, insbesondere ringförmige Scheibe 6 koaxial trägt. Auf der Achse 1 ist ferner ein Bremsbackengehäuse 7 befestigt, das drehfest angeordnet ist, d. h. nicht umläuft und in dem Bremsbacken 8 gelagert sind, die zu beiden Seiten der Scheibe 6 anliegen. Hierfür umgreift das Gehäuse 7 die Scheibe 6 U-förmig.On the outside of one of the two spoke flanges 2 , a further flange 5 is coaxially attached, in particular molded, which coaxially carries a circular, in particular annular disk 6 . On the axis 1 , a brake shoe housing 7 is also fastened, which is arranged in a rotationally fixed manner, ie does not rotate, and is mounted in the brake shoes 8 , which rest on both sides of the disk 6 . For this purpose, the housing 7 engages around the disk 6 in a U-shape.

Die Bremsbacken sind hydraulisch oder durch Bowdenzug von einem Handbremshebel aus betätigbar.The brake shoes are hydraulic or by Bowden cable from a hand brake lever can be actuated.

Die Nabenlichtmaschine und die Scheibenbremse bilden damit eine konstruktive Einheit, an der zu beiden Seiten die Achse 1 vorsteht, um mit ihren Achsenden durch Schrauben 9 an den Gabeln des Zweirades befestigt zu werden. Zwischen den beiden Gabelenden des Zweirades liegen damit sowohl die Lichtmaschine als auch die Scheibenbremse.The hub alternator and the disc brake thus form a structural unit on which the axle 1 protrudes on both sides in order to be fastened with their axle ends by screws 9 to the forks of the two-wheeler. Both the alternator and the disc brake are located between the two fork ends of the two-wheeler.

An den Nabendynamo kann ein Standlichtakku angeschlossen sein, der bei laufendem Rad ständig aufgeladen wird, so daß ein autarkes Stromversorgungssystem besteht.A parking light battery can be connected to the hub dynamo be charged while the bike is running, so that there is an autonomous power supply system.
