Abstract

Electric generator which is installed in the front wheel hub or in the bottom bracket ball bearing of a bicycle and which is intended to replace the conventional dynamo. In this case, the front wheel axle or the front wheel hub or the pedal crank or the pedal crank housing are constructed as a stator or rotor.

Beschreibung: Stromerzeuger für drehende Antriebsteile am FahrradDescription: Power generator for rotating drive parts on the bike

Die Erfindung betrifft einen Stromerzeuger, zu dem die l/arderradnabe oder das Tretlager am Fahrrad ausgebildet wird.The invention relates to a power generator to which the l / arderradnabe or the bottom bracket is designed on the bike.

Die Vorderradnabe oder das Tretlager des Fahrrades werden als Stromerzeuger gestaltet. Dadurch wird eine dauernde Stromquelle im Fahrbetrieb geschaffen, welche die Funktion des bislang außen am Fahrrad befestigten Dynamos übernimmt, so daß dieser Dynamo nicht mehr erforderlich ist.The front wheel hub or the bottom bracket of the bicycle are designed as a power generator. This creates a permanent source of electricity created during driving, which takes over the function of the dynamo previously attached to the outside of the bike, so that this dynamo is no longer required.

Die bislang für die Stromerzeugung benutzten Fahrraddynamos werden im Bedarfsfalle zugeschaltet. Zu diesem Zweck muß der Fahrradfahrende vom Fahrrad absteigen und den Dynamo mechanisch an eines der beiden Räder des Fahrrades ankuppeln, lüenn keine Stromerzeugung mehr gewünscht wird, muß der Dynamo auf dem gleichen Wege wieder angekuppelt werden.The bicycle dynamos previously used to generate electricity are switched on if necessary. For this purpose the Cyclists get off the bike and mechanically couple the dynamo to one of the two wheels of the bike, none of them run If electricity generation is more desired, the dynamo must be coupled again in the same way.

Durch ungünstige Übersetzungsverhältnisse zwischen Dynamo und Antriebsrad erfordert die Fahrradfahrt mit angekuppeltem Dynamo eine nicht unerheblich große Kraftanstrengung, als wenn der Dynamo nicht angekoppelt ist. Bei Fahrten im Regen hat der außen befestigte Dynamo den zusätzlichen Nachteil, daß er auf dem Antriebsrad rutscht und eine verminderte Energie liefert.Due to the unfavorable gear ratios between the dynamo and the drive wheel, cycling with the dynamo connected requires one not inconsiderably large effort than when the dynamo is not connected. When driving in the rain, the dynamo attached to the outside has the additional disadvantage that it slips on the drive wheel and provides reduced energy.

Bei der Erfindung entfällt das An- bzw. Auskoppeln des Stromerzeugers, weil dieser während des gesamten Fahrradbetriebes mitläuft. Durch das günstige Übersetzungsverhältnis ist der Kraftaufwand für die Betreibung des Stromerzeugers in dem Maße geringer, daß der Fahrradfahrer den hierfür erforderlichen Kraftaufwand nicht mehr bemerkt.In the invention, there is no need to connect or disconnect the power generator, because it runs along with the entire cycle. Due to the favorable transmission ratio, the effort required for operation is of the power generator to the extent that the cyclist no longer notices the effort required for this.

Beschreibung: Stromerzeuger für drehende Antriebsteile am FahrradDescription: Power generator for rotating drive parts on the bike

Ein weiterer durch die Erfindung bewirkter V/orteil liegt darin, daß eine ständige Stromquelle während des Fahrradbetriebes zur Verfügung steht, die für zusätzliche elektrische Einrichtungen am Fahrrad ( z. B. Blinker, Stopplicht usw. ) die elektrische Energie liefert.Another advantage brought about by the invention is that that a constant power source is available while the bicycle is in use for additional electrical equipment on the bicycle (e.g. indicators, stop lights, etc.) that supplies electrical energy.

Der weitere Uorteil der Erfindung liegt auch darin, daß bei Regenfahrten die Energieleistung nicht vermindert wird.The further Uorteil of the invention is that when driving in the rain the energy output is not reduced.

Ein Ausführungsbeispiel der Erfindung ist in der beigefügten Zeichnung dargestellt und wird im folgenden näher beschrieben:An embodiment of the invention is shown in the attached Drawing and is described in more detail below:

Beschreibung: Stromerzeuger für drehende Antriebsteile, am FahrradDescription: Power generator for rotating drive parts, on the bike

Die Achse des Vorderrades wird mit Wicklungen aus isolierten Drähten versehen (Stator). Die Achse ist mit einer Bohrung versehen, aus welcher die isolierten Kabel für die Stromausfuhr herausgeführt werden An der Innenseite des Nabenaußenmantels werden Dauermagnete befestigt (Rotor).The axle of the front wheel is made with windings of insulated wire provided (stator). The axle is provided with a hole from which the insulated cables for the power supply are led out Permanent magnets are on the inside of the outer hub shell attached (rotor).

Die Achse der Tretkurbel wird mit einem Dauermagneten ausgerüstet (Rotor). Die Innenseite des Außenmantels des Tretkurbelgehäuses wird mit einer Wicklung aus isolierten Drähten versehen. Durch eine Bahrung im Tretkurbelgehäuse werden zwei isolierte Kabel für die Stromausfuhr herausgeführt.The axis of the crank is equipped with a permanent magnet (rotor). The inside of the outer shell of the crankcase is provided with a winding of insulated wires. Two insulated cables are created through a hole in the crank case for the power export.
