Der als Lichtmaschine bezeichnete elektrische Generator versorgt die elektrischen Geräte an Bord eines Fahrzeugs mit elektrischem Strom. Dazu zählt auch das Laden der Starterbatterie. In Fahrzeugen mit Verbrennungsmotor wird die Lichtmaschine bzw. deren Rotor als Nebenaggregat von diesem Verbrennungsmotor zusätzlich angetrieben. Die Lichtmaschine nimmt also Energie des Fahrzeugantriebssystems ab, verringert die Fahrzeugleistung und erhöht den Treibstoffverbrauch.

Der erfindungsgemäße Wechselstromgenerator für Fahrzeuge besteht aus einem Statorteil 1 und einem Rotorteil 2. Der Statorteil 1 ist durch eine äußere Trommel 3 gebildet, in der der durch ein Schwungrad 5 gebildetes Rotorteil 2 drehbar gelagert ist. Die äußere Trommel 3 ist mit einer inneren Statorwicklung 4 und mit einer Abdeckung 8 versehen und im Innenraum eines Fahrzeugrads 11, s. Fig. 5, oder an einer Fahrzeugachse 12, s. Fig. 6, befestigt. Das Schwungrad 5 ist dagegen mit einer Rotorwicklung 6 versehen und mittels eines Lagers 7 an der Abdeckung 8 der äußeren Trommel 3 drehbar gelagert. Die Rotorwicklung 4 des Schwungrads 5 ist an einen an der Trommelabdeckung 8 angebrachten Kommutator 10 angeschlossen, von dem der Gleichstrom mit Kabeln 9 abgeführt wird. The alternator for vehicles according to the invention consists of a stator 1 and a rotor part 2. The stator 1 is formed by an outer drum 3, in which the rotor part 2 formed by a flywheel 5 is rotatably mounted. The outer drum 3 is provided with an inner stator winding 4 and a cover 8 and in the interior of a vehicle wheel 11, s. Fig. 5, or on a vehicle axle 12, s. Fig. 6, attached. The flywheel 5, however, is provided with a rotor winding 6 and rotatably supported by a bearing 7 on the cover 8 of the outer drum 3. The rotor winding 4 of the flywheel 5 is connected to a mounted on the drum cover 8 commutator 10, from which the direct current with cables 9 is discharged.
Die äußere Trommel 3, die mit dem Rad 1 oder mit der Achse 12 des Fahrzeugs verbunden ist, wird beim Anfahren des Fahrzeugs in Drehbewegung gesetzt. Das innere Schwungrad 5 von einem relativ großen Gewicht befindet sich dann in einem elektromagnetischen Kreisdrehfeld und beginnt, sich in derselben Richtung zu drehen. Wenn die Geschwindigkeit des Fahrzeugs höher wird, unterscheidet sich die Drehzahl der äußeren Trommel 3 von der Drehzahl des Schwungrads 5 The outer drum 3, which is connected to the wheel 1 or to the axle 12 of the vehicle, is set in rotary motion when starting the vehicle. The inner flywheel 5 of a relatively large weight is then in a circular electromagnetic field and begins to rotate in the same direction. As the speed of the vehicle becomes higher, the rotational speed of the outer drum 3 is different from the rotational speed of the flywheel 5
und in der Rotorwicklung 6 wird elektrische Energie erzeugt. Dies geht vor sich, bis sich die Drehzahl der Trommel 3 und die des Schwungrads 5 ausgleichen. Wenn das Fahrzeug langsamer wird, z.B. beim Bremsen, verlangsamt sich auch die Rotation der äußeren Trommel 3. Die Drehzahl des Schwungrads 5 sinkt infolge dessen kinetischer Energie wesentlich langsamer, und der Unterschied zwischen der Drehzahl der Trommel 3 und der des Schwungrads 5 hat wiederum Erzeugung der elektrischen Energie in der Rotorwicklung 6 des Schwungrads 5 zur Folge. Auch wenn das Fahrzeug stehen bleibt, dreht sich das Schwungrad 5 weiter und erzeugt elektrische Energie. Wie lange sich das Schwungrad 5 dann dreht, hängt von dessen Anfangsdrehzahl und Gewicht ab. and in the rotor winding 6, electric power is generated. This goes on until the rotational speed of the drum 3 and 5 balance the flywheel. As the vehicle slows down, eg during braking, the rotation of outer drum 3 also slows down. The speed of flywheel 5 decreases much more slowly due to its kinetic energy and the difference between the speed of drum 3 and flywheel 5 is in turn generated the electrical energy in the rotor winding 6 of the flywheel 5 result. Even if the vehicle stops, the flywheel 5 continues to rotate and generate electrical energy. How long the flywheel 5 rotates depends on its initial speed and weight.
Der Wechselstrom, der in der Rotorwicklung 6 erzeugt wird, wird mittels des The alternating current which is generated in the rotor winding 6, by means of
Kommutators 10 in Gleichstrom versetzt und über die Kabel 9 zum Stromregler geleitet, um in Batterien des Fahrzeugs gespeichert zu werden. Wenn das Fahrzeug langsamer wird oder stehen bleibt, wandelt sich die kinetische Energie des Commutator 10 is connected in DC and passed through the cable 9 to the current controller to be stored in batteries of the vehicle. As the vehicle slows down or stops, the kinetic energy of the vehicle changes

Das Aufladen der Batterien mittels des Wechselstromgenerators während des Betriebs des Fahrzeugs verlängert die Reichweite eines Elektro- oder Hybridautos bis auf das Doppelte und verringert die Frequenz des Tankens. Andererseits können die Batterien eines E-Autos bei Verwendung von erfindungsgemäßen Charging the batteries by means of the alternator during operation of the vehicle extends the range of an electric or hybrid car up to twice and reduces the frequency of refueling. On the other hand, the batteries of an electric car when using inventive

Der Wechselstromgenerator kann an einer Achse des Fahrzeugs oder an mehreren Achsen desselben Fahrzeugs verwendet werden. Die Ausführung, in der die äußere Trommel 3 im Rad 11 des Fahrzeugs untergebracht ist, kann mit der an der Achse 12 kombiniert werden. The alternator may be used on one axle of the vehicle or on multiple axles of the same vehicle. The embodiment in which the outer drum 3 is housed in the wheel 11 of the vehicle can be combined with that on the axle 12.
