  • Hybrid drives that is an alternative or combined drive of a motor vehicle by an internal combustion engine and an electric motor, are increasingly in the interest of consumers, as this not only saves fuel, but at the same time the environmental impact can be reduced. For this reason, many already offer
  • the present invention is concerned with the problem of providing an improved embodiment for a motor vehicle, which is characterized by a clever connection of an electric motor in a drive train of an internal combustion engine driven motor vehicle.
  • the present invention is based on the general idea of coupling an electric motor of a hybrid vehicle directly in the region between a first axis, for example a front axle, and a second axle, for example a rear axle, into the power flow, in particular into a drive shaft.
  • the motor vehicle according to the invention is equipped with an all-wheel drive and accordingly has a drivable first axis and a likewise drivable second axis, both of which are driven by an internal combustion engine if necessary.
  • the internal combustion engine is via a first clutch and a transmission with the second axis and above mentioned drive shaft with the first axis drivingly connected, wherein optionally only the second axis or both axes can be driven by the internal combustion engine.
  • a second clutch is arranged between the electric motor and the second axle, whereas a third clutch is provided between the electric motor and the first axle, whereby a particularly high flexibility with regard to a drive concept to be realized can be achieved.
  • the motor vehicle according to the invention is a conventional, that is
  • Combustion engine drive in all-wheel drive possible, as well as a purely internal combustion engine drive the second axis.
  • the electric motor that can be coupled in the region of the drive shaft can assume a boost function that only applies to all wheels or depending on the clutch engaged
  • the electric motor is over one
  • Motor control device connected to a vehicle battery, wherein a recuperation of the vehicle battery is optionally possible either by one of the two axes or by both axes simultaneously.
  • a purely electric motor driving is possible by an optional drive the rear axle or the front axle as well as by a four-wheel drive.
  • the individual speed levels can be switched, with a range switchover to the direct drive of the front axle is possible.
  • an at least partial drive-related decoupling of the electric motor is possible, wherein a closing of the first and second clutches at the same time makes it possible to start the internal combustion engine by means of the electric motor.
  • a further transmission is arranged between the electric motor and the third clutch.
  • This further transmission may be switchable or non-switchable and in particular have a different gear ratio than the coupled to the engine transmission.

Personenkraftwagen. Passenger cars.
Hybridantriebe, das heißt ein alternativer oder kombinierter Antrieb eines Kraftfahrzeuges durch einen Verbrennungsmotor und einen Elektromotor, stehen zunehmend im Interesse von Verbrauchern, da hierdurch nicht nur Kraftstoff gespart, sondern zugleich auch die Umweltbelastung reduziert werden kann. Aus diesem Grund bieten bereits viele Hybrid drives, that is an alternative or combined drive of a motor vehicle by an internal combustion engine and an electric motor, are increasingly in the interest of consumers, as this not only saves fuel, but at the same time the environmental impact can be reduced. For this reason, many already offer

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Kraftfahrzeug eine verbesserte Ausführungsform anzugeben, welche sich durch eine geschickte Anbindung eines Elektromotors in einen Antriebsstrang eines verbrennungsmotorisch angetriebenen Kraftfahrzeugs auszeichnet. The present invention is concerned with the problem of providing an improved embodiment for a motor vehicle, which is characterized by a clever connection of an electric motor in a drive train of an internal combustion engine driven motor vehicle.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen This problem is inventively by the subject of the independent
Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche. Claim 1 solved. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, einen Elektromotor eines Hybridfahrzeugs direkt im Bereich zwischen einer ersten Achse, beispielsweise einer Vorderachse, und einer zweiten Achse, beispielsweise einer Hinterachse, in den Kraftfluss, insbesondere in eine Antriebswelle, einzukoppeln. Das erfindungsgemäße Kraftfahrzeug ist dabei mit einem Allradantrieb ausgestattet und weist demgemäß eine antreibbare erste Achse sowie eine ebenfalls antreibbare zweite Achse auf, die beide bei Bedarf von einem Verbrennungsmotor angetrieben sind. Der Verbrennungsmotor ist dabei über eine erste Kupplung und ein Getriebe mit der zweiten Achse und über oben erwähnte Antriebswelle mit der ersten Achse antriebsverbindbar, wobei wahlweise lediglich die zweite Achse oder beide Achsen vom Verbrennungsmotor angetrieben werden können. Zwischen dem Elektromotor und der zweiten Achse ist darüber hinaus eine zweite Kupplung angeordnet, wogegen zwischen dem Elektromotor und der ersten Achse eine dritte Kupplung vorgesehen ist, wodurch eine besonders hohe Flexibilität hinsichtlich eines zu verwirklichenden Antriebskonzepts erzielt werden kann. Bei dem erfindungsgemäßen Kraftfahrzeug ist ein konventioneller, das heißt The present invention is based on the general idea of coupling an electric motor of a hybrid vehicle directly in the region between a first axis, for example a front axle, and a second axle, for example a rear axle, into the power flow, in particular into a drive shaft. The motor vehicle according to the invention is equipped with an all-wheel drive and accordingly has a drivable first axis and a likewise drivable second axis, both of which are driven by an internal combustion engine if necessary. The internal combustion engine is via a first clutch and a transmission with the second axis and above mentioned drive shaft with the first axis drivingly connected, wherein optionally only the second axis or both axes can be driven by the internal combustion engine. In addition, a second clutch is arranged between the electric motor and the second axle, whereas a third clutch is provided between the electric motor and the first axle, whereby a particularly high flexibility with regard to a drive concept to be realized can be achieved. In the motor vehicle according to the invention is a conventional, that is
verbrennungsmotorischer, Antrieb im Allradbetrieb möglich, ebenso wie ein lediglich verbrennungsmotorischer Antrieb der zweiten Achse. Der im Bereich der Antriebswelle einkoppelbare Elektromotor kann dabei insbesondere eine Boost-Funktion übernehmen, die auf alle Räder oder aber je nach geschlossener Kupplung lediglich auf die Combustion engine, drive in all-wheel drive possible, as well as a purely internal combustion engine drive the second axis. In particular, the electric motor that can be coupled in the region of the drive shaft can assume a boost function that only applies to all wheels or depending on the clutch engaged
Vorderachse oder auf die Hinterachse wirkt. Der Elektromotor ist über eine Front axle or acts on the rear axle. The electric motor is over one
Motorsteuereinrichtung mit einer Fahrzeugbatterie verbunden, wobei eine Rekuperation der Fahrzeugbatterie wahlweise durch eine der beiden Achsen oder aber durch beide Achsen gleichzeitig möglich ist. Ein rein elektromotorisches Fahren ist dabei durch einen wahlweisen Antrieb der Hinterachse oder der Vorderachse ebenso wie durch einen Allradantrieb möglich. Die einzelnen Fahrstufen können geschaltet werden, wobei auch eine Bereichsumschaltung zum Direktantrieb der Vorderachse möglich ist. Durch die zweite und dritte Kupplung ist eine zumindest teilweise antriebstechnische Entkopplung des Elektromotors möglich, wobei durch ein Schließen der ersten und zweiten Kupplung zugleich ein Starten des Verbrennungsmotors mittels des Elektromotors möglich ist. Mit dem erfindungsgemäßen Kraftfahrzeug ist es auch möglich, den Elektromotor zur Einsparung der Leerlaufbestromung komplett abzukoppeln und durch diese Motor control device connected to a vehicle battery, wherein a recuperation of the vehicle battery is optionally possible either by one of the two axes or by both axes simultaneously. A purely electric motor driving is possible by an optional drive the rear axle or the front axle as well as by a four-wheel drive. The individual speed levels can be switched, with a range switchover to the direct drive of the front axle is possible. By means of the second and third clutches, an at least partial drive-related decoupling of the electric motor is possible, wherein a closing of the first and second clutches at the same time makes it possible to start the internal combustion engine by means of the electric motor. With the motor vehicle according to the invention, it is also possible to completely decouple the electric motor to save the Leerlaufbestromung and through this
Abkoppelbarkeit eine bessere Abstimmung des Elektromotors für einen bestimmten Betriebsbereich, beispielsweise für den Betrieb bei den niedrigen Geschwindigkeiten (Berst-Drehzahl), zu ermöglichen. Ebenfalls ist durch das erfindungsgemäße Uncoupling a better tuning of the electric motor for a certain operating range, for example, to allow operation at low speeds (bursting speed). Also, by the invention
Kraftfahrzeug die Einsparung eines Anlassers möglich, wodurch das Gewicht und die Kosten für das Kraftfahrzeug reduziert werden können. Der Entfall des Anlassers ist insbesondere bei einem als Doppelkupplungsgetriebe ausgebildeten Getriebe möglich. Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist zwischen dem Elektromotor und der dritten Kupplung ein weiteres Getriebe angeordnet. Dieses weitere Getriebe kann dabei schaltbar oder nicht schaltbar sein und insbesondere ein anderes Übersetzungsverhältnis aufweisen als das mit dem Verbrennungsmotor gekoppelte Getriebe. Mit dem weiteren Getriebe ist somit auch ein rein elektromotorischer Antrieb, das heißt ein Antrieb ohne Verbrennungsmotor, denkbar, und zwar in einem deutlich verbreiterten Geschwindigkeitsbereich. Motor vehicle saving a starter possible, whereby the weight and the cost of the motor vehicle can be reduced. The elimination of the starter is possible in particular in a trained as a double clutch transmission. In an advantageous development of the solution according to the invention, a further transmission is arranged between the electric motor and the third clutch. This further transmission may be switchable or non-switchable and in particular have a different gear ratio than the coupled to the engine transmission. With the further transmission is thus also a purely electric motor drive, that is a drive without internal combustion engine, conceivable, in a much wider speed range.

Entsprechend der Figur 1, weist ein erfindungsgemäßes Kraftfahrzeug 1 eine antreibbare erste Achse 2 sowie eine ebenfalls antreibbare zweite Achse 3 auf. Ein Antrieb des Kraftfahrzeuges 1 ist dabei wahlweise oder kumulativ möglich durch einen Corresponding to FIG. 1, a motor vehicle 1 according to the invention has a drivable first axle 2 and a second axle 3 which can also be driven. A drive of the motor vehicle 1 is optionally or cumulatively possible by a
Verbrennungsmotor 4 und/oder einen Elektromotor 5. Der Verbrennungsmotor 4 ist dabei über eine erste Kupplung 6 und ein Getriebe 7, welches beispielsweise als Internal combustion engine 4 and / or an electric motor 5. The internal combustion engine 4 is via a first clutch 6 and a transmission 7, which, for example, as
Schaltgetriebe oder als Doppelkupplungsgetriebe ausgebildet sein kann, mit der zweiten Achse 3 und über eine Antriebswelle 8 mit der ersten Achse 2 antriebsverbindbar. Im Bereich zwischen der zweiten Achse 3 und der ersten Achse 2 ist dabei der Elektromotor 5 in den Kraftfluss, das heißt insbesondere in die Antriebswelle 8, welche beispielsweise als Kardanwelle ausgebildet sein kann, eingebunden. Zwischen dem Elektromotor 5 und der zweiten Achse 3 ist darüber hinaus eine zweite Kupplung 9 angeordnet, wogegen zwischen dem Elektromotor 5 und der Vorderachse 2 eine dritte Kupplung 10 Manual transmission or can be designed as a dual-clutch transmission, with the second axis 3 and via a drive shaft 8 with the first axis 2 drivably connected. In the region between the second axis 3 and the first axis 2 is the electric motor 5 in the power flow, that is, in particular in the drive shaft 8, which may be formed for example as a propeller shaft, integrated.

The third clutch 10 can be designed, for example, as a high-performance clutch, in particular as a controllable high-performance clutch.
Wie der Figur 1 weiter zu entnehmen ist, ist der Elektromotor 5 über eine Motorsteuerung 11 (ECU) mit einer Fahrzeugbatterie 12 elektrisch kommunizierend verbunden, so dass der Elektromotor 5 von der Fahrzeugbatterie 12 elektrische Energie zum Antrieb des Kraftfahrzeuges 1 erhalten kann oder aber die Fahrzeugbatterie 12 während eines Rekuperationsbetriebes aufladen kann. Zwischen dem Elektromotor 5 und der dritten Kupplung 10 ist darüber hinaus ein weiteres Getriebe 13 angeordnet, welches As can be seen further from FIG. 1, the electric motor 5 is electrically communicating with a vehicle battery 12 via an engine controller 11 (ECU), so that the electric motor 5 can receive electric energy from the vehicle battery 12 to drive the motor vehicle 1 or the vehicle battery 12 can charge during a Rekuperationsbetriebes. Between the electric motor 5 and the third clutch 10, a further transmission 13 is arranged beyond which

Gemäß der Fig. 2 ist ein Kraftfahrzeug 1 dargestellt mit einem rein elektrischen  2, a motor vehicle 1 is shown with a purely electric
Überlagerungsgetriebe 19'. Dieses kann einen integralen Bestandteil des Elektromotors 5 bilden. Wie der Fig. 2a zu entnehmen ist, besitzt dabei das elektrische  Superposition gear 19 '. This can form an integral part of the electric motor 5. As can be seen from Fig. 2a, it has the electrical
Überlagerungsgetriebe 19' einen Stator 16 sowie einen ersten Rotor 15 und einen Superposition gear 19 'a stator 16 and a first rotor 15 and a
10 zweiten Rotor 15', wobei der Stator 15 mit einer Einrichtung 17 zur Kontrolle und zu Steuerung der Leistungselektronik verbunden ist. Bei dem dargestellten elektrischen Überlagerungsgetriebe 19' bilden der erste Rotor 15 und der Stator 16 die zweite Kupplung 9 und der zweite Rotor 15' und der Stator 16 die dritte Kupplung 10' bilden. Das elektrische Übertragungsgetriebe 19' kann dabei fremd erregt oder permanent10 second rotor 15 ', wherein the stator 15 is connected to a device 17 for controlling and controlling the power electronics. In the illustrated electrical superposition gear 19 ', the first rotor 15 and the stator 16 form the second clutch 9 and the second rotor 15' and the stator 16 form the third clutch 10 '. The electrical transmission gear 19 'may be foreign or permanently excited
15 erregt sein. Auch kann das elektrische Übertragungsgetriebe 19' synchron oder 15 be energized. Also, the electrical transmission gear 19 'synchronously or
asynchron ausgebildet sein, wobei bei einer asynchronen Ausbildung der Stator 16 zumindest temporär kurzgeschlossen ist. Der große Vorteil des in Fig. 2a dargestellten elektrischen Überlagerungsgetriebes 19' ist der Wegfall eines zusätzlichen mechanischen Getriebes sowie der Wegfall eines Pulswechselrichters. Wird beispielsweise der erste be formed asynchronous, wherein in an asynchronous training, the stator 16 is at least temporarily shorted. The big advantage of the electrical superposition gear 19 'shown in Fig. 2a is the elimination of an additional mechanical transmission and the elimination of a pulse inverter. For example, the first
20 Rotor 15 erregt, erzeugt dieser im kurzgeschlossenen Stator 16 ein zugehöriges 20 excited rotor 15, this generates in the short-circuited stator 16 an associated
Magnetfeld, welches wiederum auf den zweiten Rotor 15' übertragen wird. Durch die Steuerung der Erregung des ersten Rotors 15 und/oder des zweiten Rotors 15' lässt sich eine Drehmomentenübertragung einfach und insbesondere ohne zusätzliches mechanisches Getriebe steuern. Die Steuerung kann beispielsweise über die Einrichtung Magnetic field, which in turn is transmitted to the second rotor 15 '. By controlling the excitation of the first rotor 15 and / or the second rotor 15 ', a torque transmission can be controlled simply and in particular without additional mechanical transmission. The controller may, for example, via the device
25 17 erfolgen. Das Überlagerungsgetriebe 19 ist dabei selbstverständlich bei 25 17 done. The superposition gear 19 is of course included
entsprechender Bestromung auch als elektromotorischer Antrieb nutzbar.  corresponding energizing also available as an electric motor drive.
Gemäß der Fig. 3 ist ein Kraftfahrzeug 1 dargestellt mit einer dritten Kupplung (10"), die als Überlagerungsgetriebe 19 mit Kupplungsfunktion ausgebildet ist. In Fig. 3a ist dabei die dritte Kupplung 10" in einer Detaildarstellung gezeigt, mit einer Bremse 18 und dem Überlagerungsgetriebe 19, welches einen Träger/Planet 20, ein Hohlrad 21 und ein Sonnenrad 22 aufweisen kann. Hierbei handelt es sich also um ein rein mechanisches Übertragungsgetriebe 19. 3 shows a motor vehicle 1 with a third clutch (10 "), which is designed as a superposition gear 19 with a coupling function the third clutch 10 "is shown in a detailed illustration, with a brake 18 and the superposition gear 19, which may have a carrier / planet 20, a ring gear 21 and a sun gear 22. This is therefore a purely mechanical transmission gearbox 19.
In Fig. 3b hingegen, ist im Vergleich zur Fig. 3a die Bremse 18 an anderer Stelle, insbesondere ausgangsseitig, eingekoppelt. Zugleich wirkt gemäß der Fig. 3b die Bremse 18 sowohl auf die Abtriebswelle als auch auf das Hohlrad 21 , wohingegen die Bremse 18 in Fig. 3a lediglich das Hohlrad 21 bremst und dadurch nur indirekt auf die Abtriebswelle wirkt. In contrast, in FIG. 3b, in comparison to FIG. 3a, the brake 18 is coupled in at a different location, in particular on the output side. At the same time shown in FIG. 3b, the brake 18 acts both on the output shaft and on the ring gear 21, whereas the brake 18 in Fig. 3a only the ring gear 21 brakes and thereby acts only indirectly on the output shaft.
In Fig. 3c ist der eine Kombination eines mechanischen Übertragungsgetriebes 19 mit einer elektrischen Bremse 18' gezeigt, wobei letztere auf das Hohlrad 21 des mechanischen Übersetzungsgetriebes 19 wirkt. Über die Einrichtung 17 wird eine Bremswirkung zwischen dem Stator 16 und dem ersten und einzigen Rotor 15 der elektrischen Bremse 18' gesteuert, wobei zusätzlich getriebeeingangsseitig eine Bremse 18 auf die Antriebswelle 8 einwirkt. Das Überlagerungsgetriebe 19 weist auch hier einen Träger 20, ein Hohlrad 21 und ein Sonnenrad 22 aufweist. Der Rotor 15 ist dabei mit dem Hohlrad 21 wirkungsverbunden. In Fig. 3c of a combination of a mechanical transmission gear 19 with an electric brake 18 'is shown, the latter acts on the ring gear 21 of the mechanical transmission gear 19. Via the device 17, a braking effect between the stator 16 and the first and only rotor 15 of the electric brake 18 'is controlled, wherein in addition the input side, a brake 18 acts on the drive shaft 8. The superposition gear 19 also has a carrier 20, a ring gear 21 and a sun gear 22 here. The rotor 15 is operatively connected to the ring gear 21.
Bei dem erfindungsgemäßen Kraftfahrzeug 1 ist ein Start des Verbrennungsmotors 4 im Stand somit alternativ durch den Elektromotor 5 oder den optionalen Anlasser 14 denkbar. Ein Start des Verbrennungsmotors 4 während der Fahrt kann beispielsweise mittels des Elektromotors 5 und geschlossener Kupplungen 9 und 6 erfolgen. Darüber hinaus ist eine Lastpunktverschiebung über die Antriebswelle 8 sowie die geschlossene Kupplung 9 und dem Elektromotor 5 oder aber über eine Fahrbahn denkbar. In the motor vehicle 1 according to the invention, a start of the internal combustion engine 4 in the state is thus conceivable alternatively by the electric motor 5 or the optional starter 14. A start of the internal combustion engine 4 while driving, for example, by means of the electric motor 5 and closed clutches 9 and 6 done. In addition, a load point shift via the drive shaft 8 and the closed clutch 9 and the electric motor 5 or via a roadway is conceivable.
Bei dem erfindungsgemäßen Kraftfahrzeug 1 kann ein konventioneller Allradantrieb mit einem deutlich verbesserten Wirkungsgrad realisiert werden, wobei ein Betriebsbereich des Elektromotors 5 wahlweise auf die erste Achse 2 bzw. auf die zweite Achse 3 oder auf beide Achsen 2, 3 ausdehnbar ist. Der Elektromotor 5 kann insbesondere in einem Boost-Betrieb auch auf beide Achsen 2, 3 oder aber auch nur auf die Vorderachse 2 einwirken, je nach eingestelltem Kupplungsmoment an den Kupplungen 9 und 10. Ein Rekuperieren, das heißt ein Aufladen der Fahrzeugbatterie 12 ist ebenfalls wahlweise durch eine der beiden Achsen 2, 3 oder aber durch beide Achsen 2, 3 gemeinsam möglich. Ein elektrisches Fahren kann durch ein Schließen der zweiten Kupplung 9 erfolgen, so dass der elektromotorische Antrieb auf die zweite Achse 3 wirkt, wobei selbstverständlich auch ein Schließen der dritten Kupplung 10 denkbar ist, wodurch ein elektromotorischer Allradantrieb realisierbar ist. Zur Einsparung einer In the motor vehicle 1 according to the invention, a conventional four-wheel drive can be realized with a significantly improved efficiency, with an operating range of the electric motor 5 is selectively expandable to the first axis 2 and to the second axis 3 or on both axes 2, 3. The electric motor 5, in particular in a boost operation, can also act on both axles 2, 3 or else only on the front axle 2, depending on the adjusted clutch torque on the clutches 9 and 10. Recuperation, that is to say charging of the vehicle battery 12, is likewise possible optionally by one of the two axes 2, 3 or by both axes 2, 3 together possible. An electric driving can be done by closing the second clutch 9, so that the electric motor drive acts on the second axis 3, wherein of course, a closing of the third clutch 10 is conceivable, whereby an electric motor all-wheel drive can be realized. To save a
Leerlaufbestromung kann der Elektromotor 5 durch Öffnen der zweiten Kupplung 9 und der dritten Kupplung 10, auch komplett antriebsstrangentkoppelt werden. Durch die Entkoppelbarkeit ist eine bessere Abstimmung des Elektromotors 5 für einen bestimmten Betriebsbereich möglich, beispielsweise für den Betrieb bei niedrigeren  Leerlaufbestromung the electric motor 5 can be completely decoupled by opening the second clutch 9 and the third clutch 10, also driveline. Due to the decoupling a better tuning of the electric motor 5 for a certain operating range is possible, for example, for the operation at a lower
Geschwindigkeiten (Berst-Drehzahl). Gleichzeitig kann bei dem erfindungsgemäßen Kraftfahrzeug 1 der Anlasser 14 entfallen, insbesondere sofern das Getriebe 7 als Doppelkupplungsgetriebe ausgebildet ist, da der Elektromotor 5 generell stets in der Lage ist, den Verbrennungsmotor 4 zu starten. Durch den Entfall des Anlassers 14 kann das Kraftfahrzeug 1 nicht nur leichter, sondern zudem auch kostengünstiger hergestellt werden. Speeds (bursting speed). At the same time can be omitted in the motor vehicle 1 according to the invention, the starter 14, in particular if the transmission 7 is designed as a double-clutch transmission, since the electric motor 5 is always always able to start the engine 4. Due to the elimination of the starter 14, the motor vehicle 1 can not only be made lighter, but also more cost-effective.
Bei herkömmlichen allradgetrieben Kraftfahrzeugen bestand stets die Schwierigkeit, die Drehzahlen an einem Getriebeeingang, am Motor und an der zugehörigen Achse miteinander zu koppeln. Bislang wurde dies über sogenannte hang-on-Kupplungen realisiert, was bei sehr großen Drehzahldifferenzen oft zu einer erheblichen thermischen Belastung der Kupplung, bis hin zu deren Verbrennen. Zusätzliche Schwierigkeiten traten auf bei Hybridfahrzeugen, bei denen zusätzlich ein Elektromotor in den Kraftfluss integriert werden musste. Durch die erfindungsgemäße Lösung, insbesondere gemäß der Fig. 2 und 2a, lassen sich diese Schwierigkeiten nunmehr beherrschen. In conventional four-wheel drive vehicles, there has always been the difficulty of coupling the speeds to a transmission input, to the engine and to the associated axle. So far, this has been realized via so-called hang-on clutches, which often leads to a considerable thermal load on the clutch, even up to its burning, in the case of very large speed differences. Additional difficulties arose in hybrid vehicles, in which an additional electric motor had to be integrated into the power flow. By the solution according to the invention, in particular according to FIGS. 2 and 2a, these difficulties can now be mastered.
