Abstract

A hybrid drive arrangement for vehicles, especially motor vehicles, comprises an internal combustion engine (1) having a drive shaft (6) and an electrical machine (2) lying in series with this, which machine can be connected by way of a transmission (5) to a drive axle of the vehicle for separate or common drive. In order to achieve a mode of operation which combines the speeds of the two drive components in the case of this drive arrangement, it is proposed that the electrical machine (2) comprise a rotatable, inner rotor section (3) and a rotatable outer field section (4), one of the two rotatable sections (4) being connected to the input shaft (7) of the transmission (5) and the other (3) to the drive shaft (6) of the internal combustion engine (1), which other section may at the same time constitute the necessary centrifugal mass of the crankshaft of the internal combustion engine (1) otherwise designed without a flywheel. <IMAGE>

Die Erfindung bezieht sich auf eine Rybrid-Antriebsanordnung für Fahrzeuge, insbesondere Eraftfahrzeuge, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a Rybrid drive arrangement for vehicles, in particular electric vehicles, according to the preamble of claim 1.

Herkömmliche Rybrid-Antrieb sanordnungen dieser in Einwellenkonfiguration aufgebauten Bauart weisen im allgemeinen eine Struktur auf, bei der der Läufer der elektrischen Maschine sowohl mit der Antriebswelle der Brennkraftmaschine als auch mit der Eingangswelle des Getriebes direkt verbindbar ist, so daß sich beim Betrieb beider Antriebsmaschinen eine Drehmomentaddition bei gleicher Drehzahl der Antriebskomponenten ergibt.Conventional Rybrid drive arrangements have these in a single-shaft configuration constructed type generally have a structure in which the rotor of the electrical machine both with the drive shaft of the internal combustion engine and can be directly connected to the input shaft of the transmission, so that during operation both drive machines a torque addition at the same speed of the drive components results.

Die der Erfindung zugrundeliegende Aufgabe besteht nun darin, für eine Hybrid-Antriebsanordnung der im Oberbegriff genannten Art eine andere- Struktur vorzuschlagen, die für bestimmte Anwendungsgebiete besondere Vorteile bringen könnte.The object underlying the invention is now for a hybrid drive arrangement of the type mentioned in the preamble has a different structure to propose which could bring particular advantages for certain areas of application.

Die Lösung dieser Aufgabe ergibt sich gemäß dem Kennzeichen des Patentanspruchs 1. Bei dieser ausführung wird das Drehmoment bzw. die Leistung der Brennkraftmaschine über die als Übertrager wirkende elektrische Maschine geleitet, deren beide Komponenten drehbar gelagert sein müssen. Wenn sowohl die Brennkraftmaschine als auch die elektrische Maschine mit positiver Leistung arbeiten, ergibt sich eine Drehzahladdition der beiden Komponenten bei konstantem Drehmoment.The solution to this problem results from the characterizing part of the patent claim 1. In this version, the torque or the power of the internal combustion engine passed through the electrical machine acting as a transformer, both of its components must be rotatably mounted. If both the internal combustion engine and the electric If the machine is working with positive power, the result is an addition of the speed two components at constant torque.

Zweckmäßige Weiterbildungen dieser im Anspruch 1 aufgezeigten Grundstruktur ergeben sich durch die Merkmale der Unteransprüche.Appropriate further developments of this basic structure shown in claim 1 result from the features of the subclaims.

In der Zeichnung sind verschiedene Varianten der erfindungsgemäßen Antriebsanordnung in schematischen Blockschaltbildern gezeigt, die im folgenden näher erläutert werden. Die Zeichnung zeigt in Figur 1 ein Blockschaltbild des Grundprinzips der erfindungsgemäßen Antriebsanordnung, bei der das Läuferteil der elektrischen Maschine mit der Brennkraftmaschine und das Feldteil mit dem Abtrieb verbunden ist, Figur 2 eine Ausführung der erfindungsgemäßen Antriebsanordnung, bei der das Feldteil der elektrischen Maschine mit der Brernkraftmaschine und das Läuferteil mit dem Abtrieb verbunden ist, Figur 3 eine Ausführung analog zur Ausführung nach Figur 1 mit einer zusätzlichen Dberbrückungskupplung zwischen den beiden Teilen der- elektrischen Maschine, Figur 4 eine Ausführung analog zur Figur 3 mit einer zusätzlichen Trennkupplung zwischen dem Feldteil der elektrischen Maschine und der Eingangswelle des Getriebes und Figur 5 eine Ausführung analog zu der der Figur 4, wobei noch eine zweite Trennkupplung zwischen dem Läuferteil und der Antriebswelle der Brennkraftmaschine vorgesehen ist.In the drawing are different variants of the invention Drive arrangement shown in schematic block diagrams below are explained in more detail. The drawing shows in Figure 1 a block diagram of the basic principle the drive arrangement according to the invention, in which the rotor part of the electrical The machine is connected to the internal combustion engine and the field part is connected to the output, Figure 2 shows an embodiment of the drive arrangement according to the invention, in which the field part the electrical machine with the internal combustion engine and the rotor part with the Output is connected, Figure 3 shows an embodiment analogous to the embodiment according to FIG 1 with an additional bridging clutch between the two parts of the electrical Machine, FIG. 4 an embodiment analogous to FIG. 3 with an additional separating clutch between the field part of the electric machine and the input shaft of the transmission and FIG. 5 shows an embodiment analogous to that of FIG. 4, with a second separating clutch provided between the rotor part and the drive shaft of the internal combustion engine is.

In den einzelnen Figuren der Zeichnung sind jeweils für gleiche bzw. vergleichbare Bauteile die gleichen Bezugszeichen verwendet worden Dabei wird mit 1 die- Brennkraftmaschine, mit 2 die aus einem drehbaren inneren Läuferteil 3 und einem drehbaren äußeren Feldteil 4 bestehende elektrische Maschine und mit 5 ein zu einer hier nicht weiter dargestellten Antriebsachse des Fahrzeugs führendes Getriebe bezeichnet. 6 stellt die Antriebswelle der Brennkraftmaschine und 7 die Eingangswelle des Getriebes 5 dar, während 8 eine beispielsweise durch einen Freilauf oder eine Bremse gebildete Vorrichtung zur Feststellung der Antriebswelle 6 der Brennkraftmaschine 1 und 12 eine beispielsweise durch eine Parksperre oder auch durch eine Handbremse gebildete Vorrichtung zur Feststellung der Antriebswelle 7 des Getriebes bezeichnen.In the individual figures of the drawing, the same or comparable components have been given the same reference numerals 1 the internal combustion engine, with 2 consisting of a rotatable inner rotor part 3 and a rotatable outer field part 4 existing electrical machine and with 5 a transmission leading to a drive axle of the vehicle, not shown here designated. 6 represents the drive shaft of the internal combustion engine and 7 the input shaft of the transmission 5, while 8 one for example by a freewheel or a brake formed device for locking the drive shaft 6 of the Internal combustion engine 1 and 12, for example, by a parking lock or else Device formed by a handbrake for locking the drive shaft 7 of the gearbox.

In den Figuren 1 und 2 der Zeichnung ist jeweils die Grundstruktur der erfindungsgemäßen Hybrid-Bntriebsanordnung gezeigt, bei der die Brennkraftmaschine 1 und die elektrische Maschine 2 in Reihe hintereinanderliegend über das Getriebe 5 die Antriebsachse des Fahrzeugs antreiben können. Dabei ergibt sich dadurch, daß die beiden drehbar angeordneten Teile der elektrischen Maschine 2, nämlich das Läuferteil 3 und das Feldteil 4, jeweils getrennt mit der Antriebswelle 6 der Brennkraftmaschine 1 und der Eingangswelle 7 des Getriebes 5 verbunden sind, eine Ausführung, bei der beim gleichzeitigen Arbeiten beider Antriebsmaschinen sich eine Drehzahladdition der beiden Komponenten bei gleichem Drehmoment einstellt. Hierbei ist es möglich, entweder das Läuferteil 3, dessen Trägheitsmoment kleiner als das des. Xeliteils 4 ist, oder aber, wie dies in der Figur 2 angedeutet ist, das Feldteil 4 mit der Antriebswelle 6 der Brennkraftmaschine 1 zu verbinden. Entsprechend ist dann in der Figur 1 das Feldteil 4 und in der Figur 2 das Läuferteil 3 mit der Eingangswelle 7 des Getriebes 5 verbunden.The basic structure is shown in FIGS. 1 and 2 of the drawing the hybrid drive arrangement according to the invention shown in which the internal combustion engine 1 and the electric machine 2 in series one behind the other via the transmission 5 can drive the drive axle of the vehicle. It results from the fact that the two rotatably arranged parts of the electrical machine 2, namely the rotor part 3 and the field part 4, each separated from the drive shaft 6 of the internal combustion engine 1 and the input shaft 7 of the transmission 5 are connected, an embodiment in which when both drive machines are working at the same time, an addition of speed results of the two components with the same torque. Here it is possible either the rotor part 3, whose moment of inertia is smaller than that of the Xeliteils 4, or, as indicated in FIG. 2, the field part 4 with the To connect the drive shaft 6 of the internal combustion engine 1. Accordingly, in 1 the field part 4 and in FIG. 2 the rotor part 3 with the input shaft 7 of the transmission 5 connected.

Bei diesen Anordnungen wird das Drehmoment bzw. die Leistung der Brennkraffmaschine 1 nicht direkt, sondern nur über die als über trager wirkende elektrische Maschine 2 in den Abtrieb geleitet, wobei deren beide Komponenten, d.hF sowohl das Läuferteil 3 als auch das Yeliteil 4, drehbar gelagert sein müssen.. Arbeitet dagegen die elektrische Maschine 2 allein als Antriebsmaschine, so wird auf der mit der Brennkraftmaschine 1 verbundenen Seite eine Momentenstütze benötigt, die durch die mit 8 bezeichnete Feststellvorrichtung, die als Klemmkörperfreilauf oder als Bremse ausgebildet sein kann, dargestellt wird. Wie bereits erwähnt, ergibt sich beim gleichzeitigen Arbeiten der Brennkraftmaschine 1 und der elektrischen Maschine 2, d.h. in dem Zustand, bei dem die elektrische Maschine nicht nur eine Ubertragerfunktion gegebenenfalls mit einem geissen elektrischen Restschlupf im generatorischen Betrieb ausübt, eine Drehzahladdition beider Antriebskomponenten bei gleichbleibenden Drehmoment. Hierbei wird eine besondere Regeleinrichtung benötigt, die dafür sorgt, daß ausgehend von der an der Brennkraftmaschine 1 anliegenden Last bei gleichzeitigem Betrieb auch der elektrischen Maschine 2 diese in allen möglichen Betriebsweisen des Systems auf das gleiche Drehmoment eingestellt wird.In these arrangements, the torque or the power of the internal combustion engine 1 not directly, but only via the electrical machine acting as a transferring device 2 is fed into the output, both of which are components, i.e. both the rotor part 3 as well as the Yeliteil 4, must be rotatably mounted .. On the other hand, the electrical one works If machine 2 is used alone as a drive machine, then the one with the internal combustion engine 1 connected side requires a moment support, which is indicated by the 8 Locking device, which can be designed as a clamping body freewheel or as a brake can be represented. As already mentioned, this results when working at the same time of the internal combustion engine 1 and the electric machine 2, i.e. in the state at which the electrical machine not only has a transfer function if necessary a goat electric Residual slip in generator mode exercises a speed addition of both drive components with constant torque. A special control device is required here, which ensures that starting of the load applied to the internal combustion engine 1 during simultaneous operation also the electrical machine 2 these in all possible operating modes of the system is set to the same torque.

Neben den bereits erwähnten Möglichkeiten des Fahrzeugantriebs, d.h. dem rein elektrischen Antrieb, dem Antrieb allein durch die Brennkraftmaschine und dem Antrieb durch beide Antriebsmaschinen, ergeben sich noch eine Reihe weiterer Betriebsvarianten. Dazu sei angemerkt, daß das Läuferteil 3 der elektrischen Maschine sowohl eine Schleifring- bzw. Kollektoranordnung zur Stromzu- bzw. -abfuhr aufweisen kann, wie dies z.B. bei Synchronmaschinen und Gleichstrommaschinen üblich ist. Dem Feldteil 4 ist dann eine gesonderte Schleifring- bzw. Kollektoranordnung zugeordnet. Es ist jedoch auch ohne weiteres möglich, das Läuferteil 3 der elektrischen Maschine 2 ohne ollektor- b w. bzw. Schleifringanordnungen auszubilden, wie etwa bei Asynchronmaschinen mit Käfigläufer oder bei Synchronmaschinen mit wicklungslosem Läufer (z.B. Heteropolarmaschinen).In addition to the vehicle propulsion options already mentioned, i.e. the purely electric drive, the drive solely by the internal combustion engine and the drive by both prime movers, there are a number of others Operating variants. It should be noted that the rotor part 3 of the electrical machine have both a slip ring or collector arrangement for supplying and removing electricity can, as is common with synchronous machines and DC machines, for example. To the Field part 4 is then assigned a separate slip ring or collector arrangement. However, it is also easily possible to use the rotor part 3 of the electrical machine 2 without ollektor- b w. Or slip ring arrangements, such as with asynchronous machines with squirrel cage or, in the case of synchronous machines, with a rotor without winding (e.g. heteropolar machines).

Eine derartige elektrische Maschine kann im sogenannten 4-Quadratenbetrieb betrieben werden, wobei sie entweder als Motor oder als Generator eingesetzt werden kann. Insbesondere ist es also auch mQglich, durch Betrieb der elektrischen Maschine 2 als Generator einen Bremsbetrieb mit elektrischer Nutzbremsung, d.h. mit Rückspeisung von elektrischer Energie in die der elektrischen Maschine zugeordnete Batterie, durchzuführen.Such an electrical machine can operate in so-called 4-square mode operated either as a motor or as a generator can. In particular, it is also possible by operating the electrical machine 2 as a generator, a braking operation with electrical regenerative braking, i.e. with feedback of electrical energy into the battery assigned to the electrical machine, perform.

Weiter ist es möglich, bei Einrücken der die Antriebswelle 7 des Getriebes 5 festlegenden Feststellvorrichtung 12, die beispielsweise durch eine Parksperre oder eine Handbremse gebildet sein kann, die Brennkraftmaschine 1 im Stand des Fahrzeugs durch die elektrische Maschine 2 anwerfen zu lassen. Auch im Fahrbetrieb des Fahrzeugs kann bei ausgerückter Feststellvorrichtung 12 mit Hilfe der elektrischen Maschine 2 die Brennkraftmaschine 1 angelassen werden, wobei dann die elektrische Maschine eine über tragungsfunktion in umgekehrter Richtung zu den Verhältnissen beim Antrieb durch die Brennkraftmaschine ausübt.It is also possible when the drive shaft 7 of the transmission engages 5 fixing locking device 12, for example by a parking lock or a handbrake can be formed, the internal combustion engine 1 when the vehicle is stationary to be started by the electric machine 2. Even when the vehicle is in motion can with disengaged locking device 12 with Help the electric Machine 2, the internal combustion engine 1 are started, with the electrical Machine has a transfer function in the opposite direction to the ratios exerts when driven by the internal combustion engine.

Wenn im wesentlichen nur die Brennkraftmaschine 1 als Antrieb verwendet wird, erzeugt die elektrische Maschine 2 den beim Anfahren erforderlichen Schlupf, so daß eine besondere Anfahrkupplung nicht erforderlich ist. Auch während der Fahrt des Fahrzeugs ergibt sich ein generatorischer Schlupf in der elektrischen Maschine, sofern allein die Brennkraftmaschine zum Antrieb herangezogen wird.When essentially only the internal combustion engine 1 is used as a drive is, the electric machine 2 generates the slip required when starting, so that a special starting clutch is not required. Even while driving of the vehicle results in a generator slip in the electrical machine, if only the internal combustion engine is used for the drive.

Das Getriebe 5 kann sowohl als Stufengetriebe als auch als stufenlos veränderliches Getriebe ausgebildet sein. Im Falle der Verwendung eines Stufenschaltgetriebes können die infolge der Gangstufen auftretenden Drehzahl- bzw. Drehmomentsprünge über die elektrische Maschine ausgeglichen und gedämpft werden.The transmission 5 can be used both as a multi-step transmission and as a continuously variable transmission variable transmission be formed. In the case of using a stepped gearbox the speed or torque jumps that occur as a result of the gear steps be balanced and damped via the electrical machine.

Grundsätzlich läßt sich noch sagen, daß bei der Heranziehung beider Antriebsmaschinen für den Antrieb des Fahrzeugs bei der Regelung in der Leistungsaddition die Grenzen des Drehmoments der Brennkraftmaschine, das dem Drehmoment der elektrischen Maschine gleich ist, berücksichtigt werden müssen.Basically it can be said that when both Driving machines for driving the vehicle with the regulation in the power addition the limits of the torque of the internal combustion engine, the torque of the electric Machine is the same, must be taken into account.

Durch die Trennung des Antriebsstranges im Bereich zwischen den beiden drehbaren Teilen der elektrischen Maschine 2 ergibt sich ein Dämpfungseffekt für die von der Brennkraftmaschine 1 ausgehenden Drehschwingungen, was sich vorteilhaft auf das Geräuschniveau eines derart angetriebenen Fahrzeugs auswirkt.By separating the drive train in the area between the two rotatable parts of the electrical machine 2 results in a damping effect for the torsional vibrations emanating from the internal combustion engine 1, which is advantageous affects the noise level of a vehicle driven in this way.

Bei der Ausführung nach der Figur 3 ist nun zusätzlich zu der in der Figur 1 gezeigten Struktur noch eine Uberbrückungskupplung 9 zwischen den beiden drehbaren Teilen 3, 4 der elektrischen Maschine 2 vorgesehen. Durch Einrücken dieser gegebenenfalls als Anfahrkupplung ausgebildeten Überbrückungskupplung 9 läßt sich ein herkömmlicher Betrieb eines Fahrzeugs allein durch die Brennkraftmaschine 1 verwirklichen, wobei dann die elektrische Maschine 2 stromlos geschaltet ist und zweckmäßigerweise auch die Schleifringanordnungen abgehoben sind. Die Überbrückungskupplung 9 könnte auch als umfangsspielfreie Kupplung zum starren Verbinden der beiden drehbaren Teile 3, 4 der elektrischen Maschine ausgebildet sein und beispielsweise drehzahl- und gegebenenfalls lastabhängig zur Vergrößerung der Schwungmasse der Brennkraftmaschine 1 eingerückt werden, um so beispielsweise bei niedrigen Drehzahlen einen runderen Motorlauf auch bei höheren Lasten sicherzustellen.In the embodiment according to FIG. 3, in addition to that in FIG Figure 1 structure shown still a lockup clutch 9 between the two rotatable parts 3, 4 of the electrical machine 2 are provided. By indenting this Lock-up clutch 9, which may be designed as a starting clutch, can be a conventional operation of a vehicle solely by the internal combustion engine 1 realize in which case the electrical machine 2 is de-energized and expediently the slip ring assemblies are also lifted off. The lock-up clutch 9 could Also as a coupling free of circumferential play for rigidly connecting the two rotating parts 3, 4 of the electrical machine and, for example, speed and possibly load-dependent to increase the flywheel mass of the internal combustion engine 1 to be engaged, for example a rounder one at low engine speeds Ensure that the motor runs even at higher loads.

Die geschlossene Uberbrückungskupplung 9 könnte im übrigen auch eine Parksperre ersetzen, da ein Rückwärtsrollen beispielsweise an einem Steilhang dann nicht mehr möglich ist.The closed lock-up clutch 9 could also be a Replace the parking lock, as you will then roll backwards, for example on a steep slope is no longer possible.

Wenn ein mit einer derartigen Antriebsanordnung ausgerüstetes Fahrzeug bei geschlossener Uberbrückungskupplung von der Brennkraftmaschine 1 mit Drehzahlen angetrieben wird, die unterhalb der Ruckelgrenze liegen, könnte durch Öffnen dieser uberbrückungskupplung und Zuschalten der elektrischen Maschine 2 im generatorischen Betrieb eine wirkungsvolle Dämpfung erreicht werden.When a vehicle equipped with such a drive arrangement when the lock-up clutch is closed from the internal combustion engine 1 at speeds is driven, which are below the jerk limit, could by opening this Lock-up clutch and connection of the electric machine 2 in the generator mode Effective damping can be achieved during operation.

Die Ausführung nach der Figur 4 unterscheidet sich von derjenigen der Figur 3 dadurch, daß zusätzlich noch eine erste schaltbare Trennkupplung 10 zwischen der elektrischen Maschine 2 und der Eingangswelle 7 des Getriebes 5 vorgesehen ist. Diese erste Trennkupplung könnte ebenfalls als Anfahrkupplung ausgebildet sein, so daß ein Anfahren sowohl mit der elektrischen Maschine 2 als auch mit der BrennkraStmaschine 1 über diese Kupplung möglich wäre. Wenn bei dieser Anordnung das Getriebe 5 als stufenlos veränderbares Ge-Getriebe ausgebildet wäre, könnte das mit der Eingangswelle 7 des Getriebes über die Kupplung 10 verbindbare Feldteil 4 der elektrischen Maschine 2 auch als Schwungradspeicher zur zumindest kurzzeitigen mechanischen Energiespeicherung während eines Fahrzeugbremsmanöve rs herangezogen werden. Eine entsprechende Regelung des stufenlos veränderbaren Getriebes müßte dann selbstverständlich vorgesehen sein.The embodiment according to FIG. 4 differs from that of FIG. 3 in that a first switchable separating clutch 10 provided between the electrical machine 2 and the input shaft 7 of the transmission 5 is. This first separating clutch could also be designed as a starting clutch, so that starting both with the electric machine 2 and with the internal combustion engine 1 would be possible via this coupling. If in this arrangement the transmission 5 as Infinitely variable Ge gearbox would be designed, this could be with the input shaft 7 of the transmission via the clutch 10 connectable field part 4 of the electrical machine 2 also as a flywheel storage device for at least short-term mechanical energy storage can be used during a vehicle braking maneuver. A corresponding regulation of the continuously variable transmission would then of course have to be provided.

Der Vorteil einer derartigen Ausbildung würde darin bestehen, daß dann die auf diese Weise mechanisch gespeicherte kinetische Energie für die Anfahrbeschleunigung des Fahrzeugs herangezogen werden kann, so daß keine besonders hohen Spitzenströme aus der Batterie gezogen werden müssen. Darüber hinaus erfolgt die mechanische Rückspeicherung mit einem höheren Wirkungsgrad als die elektrische Rückspeicherung.The advantage of such a training would be that then the kinetic energy mechanically stored in this way for the starting acceleration of the vehicle can be used, so that no particularly high peak currents must be removed from the battery. In addition, the mechanical restoration takes place with a higher degree of efficiency than electrical recovery.

In der in der Figur 5 gezeigten Ausführung wird nun zusätzlich zu der in der Figur 4 gezeigten Struktur noch eine zweite schaltbare Kupplung 11 zwischen der Antriebswelle 2 der Brennkraftmaschine 1 und der elektrischen Maschine 2 vorgesehen. Die Anordnung einer solchen zweiten Kupplung ist insbesondere dann sinnvoll und zweckmäßig, wenn die Antriebswelle 6 der Brennkraftmaschine 1 im wesentlichen schwungmassenlos ausgeführt ist und folglich der mit der Antriebswelle 6 über die Kupplung 11 verbindbare Teil der elektrischen Maschine 2, hier also der innere Läuferteil 3, als Schwungmasse zum Ausgleich des Drehkraftdiagramms der vorzugsweise als Hubkolben-Maschine ausgebildeten Bæ nnkraffmaschine 1 dient. Durch das Ausrücken dieser zweiten Kupplung 11 kann dann die Antriebswelle 6 der Brennkraftmaschine 1 von ihrer Schwungmasse getrennt werden, so daß die Brennkraftmaschine 1 in vielen Fällen ohne zusätzliche Maßnahmen stillgesetzt werden kann. Dies ermöglicht einen bereits bekannten Betrieb, bei dem, insbesondere während des Schubbetriebs und im Stillstand des Fahrzeugs, der Antrieb abgeschaltet und die sowohl von der Antriebsmaschine als auch von der Antriebsachse des Fahrzeugs getrennte Schwungmasse reibungsarm weiterdrehen kann, um dann die Brennkraftmaschine 1 bei nachfolgenden Antriebszuständen wieder energiesparend anwerfen zu können.In the embodiment shown in FIG. 5, in addition to the structure shown in Figure 4 also has a second switchable clutch 11 between the drive shaft 2 of the internal combustion engine 1 and the electric machine 2 are provided. The arrangement of such a second clutch is particularly useful and expedient if the drive shaft 6 of the internal combustion engine 1 is essentially without inertia is executed and consequently which can be connected to the drive shaft 6 via the coupling 11 Part of the electrical machine 2, here the inner rotor part 3, as a flywheel to compensate for the torque diagram of the preferably designed as a reciprocating piston machine Bæ nnkraffmaschine 1 is used. By disengaging this second clutch 11 can then the drive shaft 6 of the internal combustion engine 1 is separated from its flywheel so that the internal combustion engine 1 in many cases without additional measures can be shut down. This enables an already known operation in which, especially during overrun and when the vehicle is at a standstill, the drive switched off and that of both the prime mover and the drive axle of the vehicle's separate flywheel can continue to rotate with little friction, in order then to the Start internal combustion engine 1 again to save energy in the following drive states to be able to.

Bei der hier gezeigten AusSuhru kaDn die durch den inneren Läuferteil 3 gebildete Schwungmaa'sdurch das Feldteil 4 der elektrischen Maschine 2 auch in den Fällen, in denen die Drehzahl der Schwungmasse unter ein Niveau abzusinken droht, bei der nicht mehr genügend Energie zum Abwerfen der Brennkraftmaschine 1 vorhanden ist, erneut motorisch angetrieben werden. Auf diese Weise läßt sich eine ständige Motoranwurfbereitschaft selbst bei längeren Stillstandszeiten des Fahrzeugs erreichen. Ein Anwerfen des Motors erfolgt im übrigen wegen der durch die elektrische Maschine 2 erreichbaren Dämpfung weitgehend ruckfrei.In the case of the output shown here, the can through the inner part of the runner 3 swings formed by the field part 4 of the electrical machine 2 also in the cases in which the rotational speed of the flywheel threatens to drop below a level, in which there is no longer enough energy to throw off the internal combustion engine 1 is to be driven again by a motor. In this way you can have a permanent Achieve motor start-up readiness even when the vehicle is idle for long periods of time. The motor is also started because of the electrical machine 2 achievable attenuation largely jerk-free.

Die mit 8 bezeichnete Feststellvorrichtung kann bei einer Ausführung, bei der gemäß Figur 5 die zweite Kupplung il zwischen der Antriebswelle 6 der Brennkraftmaschine 1 und dem Läuferteil 3 der elektrischen Maschine 2 angeordnet ist, auch auf der der elektrischen Maschine 2 zugewandten Seite der Kupplung 11 liegen. Hierdurch würde das innere Läuferteil 3 direkt durch eine Bremse oder einen Freilauf festgelegt werden können, was für den Antrieb des Fahrzeugs allein mit der elektrischen Maschine 2 erforderlich ist.The locking device denoted by 8 can be used in an embodiment, in the case of FIG. 5, the second clutch il between the drive shaft 6 of the internal combustion engine 1 and the rotor part 3 of the electrical machine 2 is arranged, also on the the side of the clutch 11 facing the electrical machine 2. Through this the inner rotor part 3 would be set directly by a brake or a freewheel what can be used to drive the vehicle with the electric machine alone 2 is required.

Es brauchte also nicht auch die Kupplung 11 eingerückt zu werden, wenn ein rein elektromotorischer Antrieb des Fahrzeugs vorgesehen wird.So there was no need to engage clutch 11 as well, if a purely electric motor drive of the vehicle is provided.

Die Anordnung dieser zweiten schaltbaren Kupplung ii ermöglicht es insbesondere dann, wenn die Überbrückungskupplung 9 zwischen den beiden drehbaren Teilen 3,4 der elektrischen Maschine 2 vorgesehen ist, diese beiden Teile für eine rein mechanische Speicherung der kinetischen Energie heranzuziehen, während bei Fehlen dieser Uberbrückungskupplung 9 eine Kopplung lediglich elektrisch hergestellt würde.The arrangement of this second switchable clutch ii makes it possible especially when the lock-up clutch 9 is rotatable between the two Parts 3, 4 of the electrical machine 2 is provided, these two parts for one to use purely mechanical storage of the kinetic energy, while at If this bridging clutch 9 is absent, a coupling is only established electrically would.

Es sei schließlich darauf hingewiesen, daß, abgesehen von den in der Zeichnung gezeigten Ausführungsbeispielen, noch eine Vielzahl weiterer Alternativen möglich sind, in denen die einzelnen Elemente unterschiedlich miteinander kombiniert werden. So ist es beispielsweise ohne weiteres möglich, die in dem Figuren 3 bis 5 gezeigten Strukturen auch bei einer Anordnung zu treffen, bei der, wie in der Figur 2, nicht das innera Läuferteil 3 sondern das äußere Feliteil 4 mit der Antriebswelle 6 der Brennkraftmaschine 1 verbunden ist.Finally, it should be noted that, apart from those in the Embodiments shown in the drawing, a large number of other alternatives are possible in which the individual elements are combined in different ways will. So it is, for example, easily possible, in the figures 3 to 5 to meet the structures shown in an arrangement in which, as in FIG FIG. 2, not the inner rotor part 3 but the outer rotor part 4 with the drive shaft 6 of the internal combustion engine 1 is connected.

Darüber hinaus lassen sich auch die erste Kupplung 10 und die zweite Kupplung 11 mit und ohne uberbrückungskupplung 9 ausführen.In addition, the first clutch 10 and the second Execute clutch 11 with and without bridging clutch 9.
