Schließlich ist es nicht erforderlich, daß der Ständer den gesamten Rotorumfang bedeckt, wodurch sich der Generator besonders raumsparend unterbringen läßt. Wenn der Stator in mehrere Segmente aufgeteilt ist, kann in vorteilhafter Weise an jedes der Segmente ein eigener Verbraucherkreis angeschlossen werden, bei spielsweise Verbraucher mit einer anderen Spannungslage oder Wechselspannungsverbraucher.

Es sollen nur diejenigen Teile der an sich bekannten Anordnung beschrieben werden, die für das Verständnis der Erfindung von Wichtigkeit sind.Description of the exemplary embodiments FIG. 1 shows the structure of a heteropolar generator as used for the invention, and a longitudinal section through the housing of a vehicle drive, for example with an internal combustion engine, with a particular view of the flywheel and the clutch. It's just supposed to those parts of the arrangement known per se are described which are necessary for the Understanding the invention are important.
Eine Kurbelwelle 21 mit einer Wange 22 ist mit Hilfe eines Gleitlagers 23 im Gehäuse 24 des Verbrennungsmotors gelagert.A crankshaft 21 with a cheek 22 is with the help of a plain bearing 23 stored in the housing 24 of the internal combustion engine.
Auf das Motorgehäuse 24 ist ein Kupplungsgehäuse 25 aufgesetzt, das unter anderem die Kupplung 26 enthält. Auch ein Schwungrad 27, das mit Hilfe von Schrauben 28 an die Kurbelwelle 21 angeflanscht ist, ist im Kupplungsgehäuse 25 enthalten.A clutch housing 25 is placed on the motor housing 24, which among other things, the clutch 26 contains.

Bei der Erfindung sind der Stator 11 und der Rotor 18 gebleicht, also lamelliert, ausgeführt.A stator 11 is fastened in the clutch housing 25. The stator il carries an excitation winding 12 and an AC output winding 13th The windings 12 and 13 lie in grooves 15 between teeth 16. In the bore of the A rotor 18 is mounted on the stator 11 so as to be rotatable about the shaft 17. The rotor 18 has To generate fluctuations in conductance, teeth 19 which are directed towards the stator 11 or consists of a laminated, meandering sheet metal ring, which partially protrudes into the U-shaped stator 11. In the invention are the The stator 11 and the rotor 18 are bleached, i.e. laminated.
Es ist nicht erforderlich, daß sich der Stator 11 über den gesamten Umfang des Rotors 18 erstreckt. Wegen des verhältnismäßig großen Durchmessers des Rotors 18, der durch den Durchmesser des Schwungrades 27 bedingt ist, kann die geforderte Generatorleistung von einem Stator 11 geliefert werden, der nur einen Teil des Umfangs des Rotors 18 bedeckt.It is not necessary that the stator 11 over the entire The circumference of the rotor 18 extends. Because of the relatively large diameter of the Rotor 18, which is caused by the diameter of the flywheel 27, can be the required Generator power can be supplied by a stator 11, which is only part of the circumference of the rotor 18 covered.
Es ist möglich, den Stator 11 in eine Mehrzahl von Segmenten aufzuteilen und entsprechend dem Statorteil 11 in Figur 1 im Kupplungsgehäuse anzuordnen. Jedes einzelne Segment kann dann beispielsweise über voneinander getrennte Ausgangswicklungen 13a, 13b ... einen eigenen Teil des Bordnetzes, beispielsweise mit abweichender Spannungslage oder einen Wechselspannungsverbraucher, speisen.It is possible to divide the stator 11 into a plurality of segments and to be arranged in the coupling housing in accordance with the stator part 11 in FIG. Each individual segments can then, for example, have output windings that are separate from one another 13a, 13b ... a separate part of the vehicle electrical system, for example with a different one Voltage level or an AC voltage consumer.
In einem Ausführungsbeispiel der Erfindung ist in Figur 2 der Rotor 18 als geblechtes Zahnrad mit Zähnen 19 ausgebildet.In one embodiment of the invention, the rotor is shown in FIG 18 designed as a laminated gear with 19 teeth.
Dieses Zahnrad 18, 19 ist, wie schon beschrieben, auf das Schwungrad 27 aufgesetzt. In radialer Richtung längs des Umfangs des Zahnrades 18, 19 ist der Stator 11 in Form eines Kreis-Segments angeordnet. Das Segment 11 trägt eine Erregerwicklung 12, die beispielsweise um das Mittelstück des Segments 11 gewickelt ist, und eine Wechselstrom-Ausgangswicklung 13, die in Nuten 15 auf der dem Rotor 18 zugewandten Seite des Segments eingelegt sind. Im übrigen sind in Figur 2 und in den folgenden Figuren für gleiche Bauteile die gleichen Bezugszeichen auch wie in Figur 1 verwendet.This gear 18, 19 is, as already described, on the flywheel 27 put on. In the radial direction along the circumference of the gear 18, 19 is the Stator 11 arranged in the form of a circular segment. The segment 11 carries an excitation winding 12, which is wrapped around the center piece of segment 11, for example, and a AC output winding 13, which is in slots 15 on the rotor 18 facing Side of the segment are inserted. In addition, in Figure 2 and in the following In the figures, the same reference numerals are also used as in FIG. 1 for the same components.
Durch die Ausführungsbeispiele in Figur 2 und 3 lassen sich bei einer relativ kleinen Rotorzähnezahl aufgrund der günstigen mittleren Windungslänge der Erregerwicklung eine hohe Erregerdurchflutung bei einer vorgegebenen Betriebsspannung im gegebenen Wickelraum unterbringen. Gegenüber Ausführungen mit einer längs des Umfangs in zwei Spulen verteilten Erregerwicklung 12 läßt sich durch die Anordnung der Erregerwicklung 12 gemäß dem Ausführungsbeispiel nach Figur 2 oder 3 ein Generator mit günstigerem Leistungsgewicht erzielen.The exemplary embodiments in FIGS. 2 and 3 can be used in one relatively small number of rotor teeth due to the favorable mean winding length of the Excitation winding has a high excitation flow at a given operating voltage in the given changing room. Compared to versions with a lengthways Excitation winding 12 distributed around the circumference in two coils can be determined by the arrangement the excitation winding 12 according to the embodiment of Figure 2 or 3 is a generator Achieve with a cheaper power-to-weight ratio.
Im Ausführungsbeispiel nach Figur 3 sind die Zähne 19 des geblechten Zahnrades 18, das den Rotor bildet und auf dem Schwungrad 27 befestigt ist, in axialer Richtung angeordnet.In the exemplary embodiment according to FIG. 3, the teeth 19 of the are laminated Gear 18, which forms the rotor and is mounted on the flywheel 27, in the axial Direction arranged.
Ebenfalls in axialer Richtung steht dem Zahnrad 18, 19 ein Statorsegment 11 gegenüber. Die Erregerwicklung 12 und die Ausgangswicklung 13 sind wie beim Ausführungsbeispiel nach Figur 2 vorgesehen. Aller Läufer-Zahnkranz 13, 19 und die Statorsegmente 11 lassen sich aus Streifen von Dynamoblech herstellen, dabei werden zuerst die Nuten unter Berücksichtigung der Durchmesseränderung gestanzt und dann der Zahnkranz 18, 19 und das Statorsegment 12 als Wickel gefertigt. Nach einem Fixieren der ringförmigen Wickel durch Kleben oder Nieten lassen sich die Statorsegmente 11 aus den betreffenden Ringen herausschneiden. Eine Nachbearbeitung ist nur auf der genuteten Stirnseite der ringförmigen Wickel und für den Fall einer formschlüssigen Befestigung auf der Innenseite oder Außenseite des Liäuferzahnrades 18, 19 auf dem Schwungrad 27 erforderlich.The gearwheel 18, 19 is also provided with a stator segment in the axial direction 11 opposite. The excitation winding 12 and the output winding 13 are as in the embodiment provided according to Figure 2. All rotor ring gear 13, 19 and the stator segments 11 can be made from strips of dynamo sheet, the grooves being made first Punched taking into account the change in diameter and then the ring gear 18, 19 and the stator segment 12 made as a winding. After fixing the ring-shaped Winding by gluing or riveting, the stator segments 11 can be made from the relevant Cut out the rings. Post-processing is only possible on the grooved face the annular winding and in the event of a form-fitting attachment on the Inside or outside of the runner gear 18, 19 on the flywheel 27 is required.
Figur 4 zeigt zwei Varianten eines weiteren Ausführungsbeispieles. Auf dem Schwungrad 27 ist ein mäanderförmiger geblechter Rotorkranz 18 befestigt. Geblechte Statorsegmente 11 tragen eine konzentrierte Erregerwicklung 12 und eine verteilte - Figur 4a - oder konzentrierte - Figur 4b - Wechselstrom-Ausgangswicklung 13.Figure 4 shows two variants of a further embodiment. A meander-shaped laminated rotor ring 18 is attached to the flywheel 27. Laminated stator segments 11 carry a concentrated field winding 12 and a distributed - Figure 4a - or concentrated - Figure 4b - AC output winding 13th
In Figur 5 ist gezeigt, wie der mäanderförmige Rotorkranz 18 auf dem Schwungrad 27 befestigt werden kann. Im Ausführungsbeispiel nach Figur 5a ist der Rotorkranz 18 durch einen den Rotorkranz 18 halbseitig umschließenden Blechmantel 31 am Schwungrad 27 befestigt. Im Ausführungsbeispiel nach Figur 5b ist der Rotorkranz 18 mit Hilfe von Stiften 32 befestigt. Die Stifte 32 können von Isolierhülsen 33 umgeben sein; dies ist in Figur 5c dargestellt. Schließlich kann der Rotorkranz 18 einseitig in ein nichtmagnetisches Material 34 eingegossen sein. Als besonders günstig hat sich hierfür Aluminium erwiesen. Der Rotorkranz 18 ist dann zusammen mit diesem umgossenen nichtmagnetischen Material 3)1 auf dem Schwungrad 27 befestigt.In Figure 5 it is shown how the meander-shaped rotor ring 18 on the Flywheel 27 can be attached. In the embodiment of Figure 5a is the Rotor rim 18 by a sheet metal jacket surrounding the rotor rim 18 on one side 31 attached to the flywheel 27. In the embodiment of Figure 5b is the rotor ring 18 attached by means of pins 32. The pins 32 can be from insulating sleeves 33 be surrounded; this is shown in Figure 5c. Finally, the rotor ring can 18 cast into a non-magnetic material 34 on one side. As special Aluminum has proven to be beneficial for this. The rotor ring 18 is then together attached to the flywheel 27 with this encapsulated non-magnetic material 3) 1.
Dadurch, daß der Rotorkranz 18 bei den Ausführungsbeispielen nach Figur 4 und 5 von dem Statorsegment oder den Statorsegmenten 11 beidseitig umschlossen ist, ist die vom Generator abgegebene Leistung unabhängig vom Lagerspiel des Rotors 18 oder des Schwungrades 27. Die geblechten Statorsegmente 11 lassen sich als Halbschnitte - Figur 4a - oder aus einzelnen Teilschnitten - Figur 4b - aurschichten und zusammenfügen.The fact that the rotor ring 18 in the embodiments according to FIGS. 4 and 5 enclosed on both sides by the stator segment or segments 11 is, the power delivered by the generator is independent of the bearing play of the rotor 18 or the flywheel 27. The laminated stator segments 11 can be made as half-sections - Figure 4a - or from individual partial sections - Figure 4b - aurschichten and join.
Die Wicklungen 12, 13 lassen sich fertigungstechnisch sehr vorteilhaft als konzentrierte Spulen herstellen und dann als fertige Spulen einlegen.The windings 12, 13 can be very advantageous in terms of production technology as concentrated coils and then insert as finished coils.
Figur 6 zeigt ein Ausführungsbeispiel, bei dem die Stator-Sektor-Segmente 11 hufeisenförmig ausgebildet und mit Nuten in Form von Schlitzen 35, 36 für die Ausgangswicklung 13 und die Erregerwicklung 12 versehen sind. Die abgegebene elektrische Leistung des Generators wird damit auch bei diesem Ausführungsbeispiel weitgehend unabhängig vom Lagerspiel des Rotors 18.Figure 6 shows an embodiment in which the stator sector segments 11 horseshoe-shaped and with grooves in the form of slots 35, 36 for the Output winding 13 and the excitation winding 12 are provided. The delivered electrical The power of the generator is thus largely also in this exemplary embodiment regardless of the bearing play of the rotor 18.
Außerdem ergibt sich durch die gewählte Formgebung eine kleine mittlere Leiterlänge für die Erregerwicklung 12 und die Ausgangswicklung 13.In addition, the shape selected results in a small average Conductor length for the excitation winding 12 and the output winding 13.
