Description

Die vorliegende Erfindung betrifft eine Antriebsvorrichtung mit einer elektrischen Maschine nach dem Oberbegriff des Anspruches 1. Insbesondere betrifft die vorliegende Erfindung eine Antriebsvorrichtung für ein Kraftfahrzeug, welche eine in Form eines Starter/Generator-Systems ausgestaltete elektrische Maschine aufweist.The present invention relates to a drive device with an electrical Machine according to the preamble of claim 1. In particular, the present relates Invention a drive device for a motor vehicle, which is in the form of a Starter / generator system designed electrical machine.

Starter/Generator-Systeme sind weitläufig bekannt und zwischen einem Antriebsmotor, in der Regel einem Verbrennungsmotor, und einem Getriebe des Kraftfahrzeugs angeordnet. Derartige Starter/Generator-Systeme ermöglichen einerseits einen einfacheren Start des Antriebsmotors und andererseits eine hohe Generatorleistung, um Energie für bestimmte Verbraucher des Kraftfahrzeugs bereitzustellen.Starter / generator systems are widely known and between a drive motor, usually an internal combustion engine, and a transmission of the motor vehicle arranged. Such starter / generator systems on the one hand enable one easier start of the drive motor and on the other hand a high generator power to To provide energy for certain consumers of the motor vehicle.

Der grundsätzliche Aufbau von Antriebsvorrichtungen mit Starter/Generator-Systemen ist in Fig. 2 dargestellt und kann beispielsweise den Druckschriften WO 98/05882 oder DE 196 16 504 A1 entnommen werden. Dabei zeigt Fig. 2 den Antriebsstrang eines Kraftfahrzeugs, wobei als Antriebsaggregat ein Verbrennungsmotor 1 verwendet wird. Die Kurbelwelle 2 des Verbrennungsmotors ist über eine Trennkupplung 3 mit einer als Starter/Generator-System dienenden elektrischen Maschine 4 verbunden, welche einen Rotor 6 und einen den Rotor 6 umgebenden Stator 5 umfaßt. Die Wicklungen des Stators 5 sind mit der Kraftfahrzeugbatterie sowie elektrischen Verbrauchern des. Kraftfahrzeugs verbunden, was in Fig. 2 allgemein durch das mit dem Stator 5 verbundene Bordnetz 11 des Kraftfahrzeugs angedeutet ist. Der Rotor 6 der elektrischen Maschine 4 steht abtriebsseitig über eine Getriebekupplung 8 mit der Getriebeeingangswelle 7 eines Getriebes 9 in Verbindung, über welches das Antriebsdrehmoment auf die Antriebsräder 10 des Kraftfahrzeugs übertragen wird.The basic structure of drive devices with starter / generator systems is shown in FIG. 2 and can be found, for example, in documents WO 98/05882 or DE 196 16 504 A1. In this Figure 2 being used as the prime mover, an internal combustion engine. 1 shows the drive train of a motor vehicle. The crankshaft 2 of the internal combustion engine is connected via a separating clutch 3 to an electrical machine 4 serving as a starter / generator system, which comprises a rotor 6 and a stator 5 surrounding the rotor 6 . The windings of the stator 5 are connected to the motor vehicle battery and electrical consumers of the motor vehicle, which is generally indicated in FIG. 2 by the vehicle electrical system 11 connected to the stator 5 . The rotor 6 of the electrical machine 4 is connected on the output side via a gear coupling 8 to the gear input shaft 7 of a gear 9 , via which the drive torque is transmitted to the drive wheels 10 of the motor vehicle.

Die als Starter/Generator-System dienende elektrische Maschine 4 wird in zwei unterschiedlichen Betriebsmodi betrieben. In einem Motorbetrieb übernimmt die elektrische Maschine 4 bei Betätigen des Anlasserschlüssels die Funktion eines Anlassers oder Motors zum Starten des Verbrennungsmotors 1. Hierzu werden den Statorwicklungen 5 entsprechende Erregerströme derart zugeführt, daß der Rotor 6 mit einem Anlaufdrehmoment beaufschlagt wird, welches das Starten des Verbrennungsmotors 1 erleichtert. Nach dem Starten des Verbrennungsmotors 1 schaltet die elektrische Maschine 4 in einen Generatorbetrieb um, in dem der Rotor 6 über die Kurbelwelle 2 des Verbrennungsmotors 1 in Rotation versetzt und somit in den Statorwicklungen 5 eine Spannung induziert wird, welche zur Energieversorgung des Bordnetzes 11 bzw. der daran angeschlossenen Verbraucher des Kraftfahrzeuges dient.The electrical machine 4 serving as a starter / generator system is operated in two different operating modes. In an engine operation, the electric machine 4 takes over the function of a starter or motor for starting the internal combustion engine 1 when the starter key is actuated. For this purpose, corresponding excitation currents are supplied to the stator windings 5 in such a way that a starting torque is applied to the rotor 6 , which facilitates the starting of the internal combustion engine 1 . After starting the internal combustion engine 1 , the electrical machine 4 switches to generator operation, in which the rotor 6 rotates via the crankshaft 2 of the internal combustion engine 1 and thus a voltage is induced in the stator windings 5 , which voltage is used to supply power to the vehicle electrical system 11 or the connected consumer of the motor vehicle serves.

In der WO 98/05882 wird darüber hinaus vorgeschlagen, in den Rotor 6 eine Schwingungsbedämpfung oder einen Drehschwingungstiler zu integrieren, wobei diese Anordnung beispielsweise in Form eines Zwei-Massen-Schwungrads ausgestaltet ist und den Rotor 6 mit der Getriebeeingangswelle 7 verbindet. Des weiteren wird in der WO 97/21560 ausgeführt, daß der Rotor 6 der elektrischen Maschine 4 grundsätzlich ein Massenträgheitsmoment darstellt und daher zugleich die Funktion eines Schwungrads für den Verbrennungsmotor 1 übernehmen kann.In WO 98/05882 it is also proposed to integrate vibration damping or a torsional vibration damper into the rotor 6 , this arrangement being designed, for example, in the form of a two-mass flywheel and connecting the rotor 6 to the transmission input shaft 7 . Furthermore, it is stated in WO 97/21560 that the rotor 6 of the electrical machine 4 basically represents a moment of inertia and can therefore also take over the function of a flywheel for the internal combustion engine 1 .

Zudem ist in der in der EP 0 724 978 A1 eine gattungsgemäße Antriebsvorrichtung nach dem Oberbegriff des Anspruches 1 offenbart. Der grundsätzliche Aufbau dieser Antriebsvorrichtung ist in Fig. 3 dargestellt und entspricht weitgehend dem in Fig. 2 gezeigten Aufbau. Die Antriebsvorrichtung stellt in diesem Fall einen Parallelhybridantrieb für ein Kraftfahrzeug dar und umfaßt ein Schaltgetriebe 9, welches ein veränderbares Drehzahlverhältnis seiner Getriebeeingangswelle 7 zu seiner mit den Antriebsrädern des Kraftfahrzeugs verbundenen Getriebeausgangswelle 13 besitzt. Die Getriebeeingangswelle 7 ist über eine Trennkupplung 8 mit einer elektrischen Maschine 4 verbunden, welche wiederum einen ortsfesten Stator 5 und einen drehbaren Rotor 6 umfaßt. Über einen weiteren Drehmomentübertragungsweg ist die Getriebeeingangswelle 7 mit der Kurbelwelle 2 eines Verbrennungsmotors 1 verbunden, wobei in diesen Drehmomentübertragungsweg eine überbrückbare Freilaufkupplung 3 angeordnet ist, welche im Motorbetrieb der elektrischen Maschine selbstätig öffnet und somit den Verbrennungsmotor 1 von der Getriebeeingangswelle 7 abkuppelt, während die Freilaufkupplung 3 bei Antrieb des Kraftfahrzeuges ausschließlich durch den Verbrennungsmotor 1, d. h. wenn die elektrische Maschine 4 stromlos geschaltet ist oder im Generatorbetrieb arbeitet, selbstätig eingekuppelt ist. Wie der Darstellung von Fig. 3 entnommen werden kann, sind die elektrische Maschine 4 mit dem Stator 5 und dem Rotor 6 sowie die Getriebekupplung 8 in einem gemeinsamen, dem Getriebe 9 zugeordneten Gehäuse 12 untergebracht. In addition, a generic drive device according to the preamble of claim 1 is disclosed in EP 0 724 978 A1. The basic structure of this drive device is shown in FIG. 3 and largely corresponds to the structure shown in FIG. 2. The drive device in this case represents a parallel hybrid drive for a motor vehicle and comprises a manual transmission 9 which has a variable speed ratio of its transmission input shaft 7 to its transmission output shaft 13 connected to the drive wheels of the motor vehicle. The transmission input shaft 7 is connected via a separating clutch 8 to an electrical machine 4 , which in turn comprises a stationary stator 5 and a rotatable rotor 6 . The transmission input shaft 7 is connected to the crankshaft 2 of an internal combustion engine 1 via a further torque transmission path, with a lockable one- way clutch 3 being arranged in this torque transmission path, which opens automatically during motor operation of the electrical machine and thus uncouples the internal combustion engine 1 from the transmission input shaft 7 while the one-way clutch 3 when the motor vehicle is driven exclusively by the internal combustion engine 1 , ie when the electrical machine 4 is switched off or is operating in generator mode, is automatically engaged. As can be seen from the illustration in FIG. 3, the electrical machine 4 with the stator 5 and the rotor 6 and the gear coupling 8 are accommodated in a common housing 12 assigned to the gear 9 .

Die für den Start des Verbrennungsmotors 1 und als Generator für die Bordnetzversorgung vorgesehene elektrische Maschine wirkt direkt ohne Zwischenübersetzung auf die Kurbelwelle 2 des Verbrennungsmotors 1, so daß die elektrische Maschine wegen der relativ großen Startmomente ein nicht unbeträchtliches Bauvolumen einnimmt. Da der Raum zwischen dem Verbrennungsmotor 1 und dem Getriebe 9 in der Regel ausschließlich für die Aufnahme der Getriebekupplung 8 oder eines entsprechenden Wandlers ausgelegt ist, führt die zusätzliche Anordnung einer elektrischen Maschine in diesem Bereich zwangsläufig dazu, daß der Motor 1 oder das Getriebe 9 räumlich verschoben werden muß, was insbesondere bei großen Motoren aufgrund der Motorraummenge nicht realisierbar ist.The provided for the start of the internal combustion engine 1 and as a generator for the on-board electrical system acts directly without intermediate translation on the crankshaft 2 of the internal combustion engine 1 , so that the electrical machine takes up a not inconsiderable volume due to the relatively large starting torques. Since the space between the internal combustion engine 1 and the transmission 9 is usually designed exclusively for receiving the transmission clutch 8 or a corresponding converter, the additional arrangement of an electrical machine in this area inevitably leads to the fact that the motor 1 or the transmission 9 spatially must be moved, which is not feasible in particular in large engines due to the amount of engine space.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Antriebsvorrichtung mit einer zwischen einem Antriebsaggregat und einem Getriebe der Antriebsvorrichtung angeordneten elektrischen Maschine bereitzustellen, bei der die elektrische Maschine problemlos in den beschränkt verfügbaren Bauraum zwischen dem Antriebsaggregat und dem Getriebe untergebracht werden kann, so daß insbesondere keine räumliche Verschiebung des Antriebsaggregats oder des Getriebes erforderlich ist.The present invention is therefore based on the object of a drive device with one between a drive unit and a transmission of the drive device to provide arranged electrical machine in which the electrical machine easily in the limited space available between the drive unit and the transmission can be accommodated, so that in particular no spatial Displacement of the drive unit or the gearbox is required.

Diese Aufgabe wird erfindungsgemäß durch eine Antriebsvorrichtung mit den im Anspruch 1 angegebenen Merkmalen gelöst. Die Unteransprüche beschreiben bevorzugte Ausführungsformen der Erfindung.This object is achieved by a drive device with the Features specified claim 1 solved. Describe the subclaims preferred embodiments of the invention.

Die vorliegende Erfindung sieht vor, den Kupplungsraum in der Getriebeglocke durch eine andere Kupplungsauslegung so auszunutzen, daß die elektrische Maschine leicht untergebracht werden kann. Zu diesem Zweck wird der äußere Ringraum der Getriebeglocke durch die elektrische Maschine belegt, während die Getriebekupplung im mittleren Bereich der Getriebeglocke angeordnet wird. Insbesondere ist die Anordnung derart, daß das Gehäuse der Getriebekupplung als Träger für den Rotor der elektrischen Maschine dient.The present invention provides for the clutch space in the bell housing to use another coupling design so that the electrical machine easily can be accommodated. For this purpose, the outer annulus of the Transmission bell occupied by the electrical machine, while the transmission clutch in middle area of the bell housing is arranged. In particular, the arrangement such that the housing of the gear coupling as a carrier for the rotor of the electrical Machine serves.

Durch die Anordnung der elektrischen Maschine in dem äußeren Ringraum der Getriebeglocke kann die elektrische Maschine bei maximalem Hebelarm bzw. größtmöglichem Spulen-Ringvolumen wirken. By arranging the electrical machine in the outer annulus of the The bell can be operated by the electrical machine with the maximum lever arm or maximum possible coil ring volume.  

Die innerhalb des Rotors der elektrischen Maschine angeordnete Getriebekupplung kann sowohl als Naß- oder Trockenkupplung ausgestaltet sein. Die Getriebekupplung ist vorzugsweise eine Mehrscheibenkupplung.The gear coupling arranged inside the rotor of the electrical machine can be designed both as a wet or dry clutch. The gearbox clutch is preferably a multi-disc clutch.

Des weiteren kann ein Zwei-Massen-Schwungrad mit großem Wirkdurchmesser neben der elektrischen Maschine oder im Getriebekupplungsbereich, dann jedoch mit kleinerem Wirkdurchmesser, angeordnet sein.Furthermore, a two-mass flywheel with a large effective diameter can also be used the electrical machine or in the gear coupling area, but then with a smaller one Effective diameter, be arranged.

Die elektrische Maschine kann mehrstufig ausgestaltet sein, wobei insbesondere eine dreistufige Ausgestaltung in Betracht kommt, bei der jede Stufe für 12 V ausgelegt ist, um ein 36-V-Bordnetz versorgen zu können.The electrical machine can be configured in several stages, in particular one three-stage design comes into consideration, in which each stage is designed for 12 V to to be able to supply a 36 V electrical system.

Der oder die Rotoren können nicht nur fest auf dem Gehäuse der Getriebekupplung angeordnet werden. Vielmehr kann es auch vorteilhaft sein, zwischen dem Rotor bzw. den Rotoren der elektrischen Maschine und dem Kupplungsgehäuse eine gewisse Verdrehung zu ermöglichen, welche durch definierte Reibmomente oder auch durch elastische Spannelemente zwischen dem Rotor bzw. den Rotoren und dem Kupplungsgehäuse im Sinne einer Drehschwingungsbedämpfung beeinflußt wird, so daß eine die Antriebswellen-Drehschwingungen des Antriebsaggregats bedämpfende Wirkung ähnlich zu einem Zwei-Massen-Schwungrad oder einem Drehschwingungstilger erzielt wird.The rotor or rotors can not only be fixed on the housing of the gear coupling to be ordered. Rather, it can also be advantageous to place between the rotor or the rotors of the electrical machine and the clutch housing a certain To enable rotation, which by defined moments of friction or by elastic clamping elements between the rotor or the rotors and the Coupling housing is influenced in the sense of torsional vibration damping, so that a damping the drive shaft torsional vibrations of the drive unit Effect similar to a two-mass flywheel or a torsional vibration damper is achieved.

Die vorliegende Erfindung wird vorzugsweise in einem Kraftfahrzeug verwendet, wobei als Antriebsaggregat ein Verbrennungsmotor zum Einsatz kommt, dessen Antriebsdrehmoment über eine Kurbelwelle auf den Rotor der als Starter/Generator- System ausgebildeten elektrischen Maschine und das Getriebe übertragen wird. In diesem Fall wird die elektrische Maschine, wie eingangs beschrieben worden ist, in einem ersten Betriebsmodus zum Starten des Verbrennungsmotors und nach dem Starten des Verbrennungsmotors in einem zweiten Betriebsmodus als Energieversorger für elektrische Verbraucher des Kraftfahrzeuges verwendet. Die vorliegende Erfindung kann jedoch grundsätzlich überall dort eingesetzt werden, wo die der Erfindung zugrundeliegende Problematik gegeben ist.The present invention is preferably used in a motor vehicle, wherein an internal combustion engine is used as the drive unit Drive torque via a crankshaft to the rotor which acts as a starter / generator System trained electrical machine and the transmission is transmitted. In in this case, the electrical machine, as described at the beginning, in a first operating mode for starting the internal combustion engine and after Starting the internal combustion engine in a second operating mode as an energy supplier used for electrical consumers of the motor vehicle. The present invention can, however, basically be used wherever the invention underlying problem is given.

Nachfolgend wird die vorliegende Erfindung unter Bezugnahme auf die beigefügte Zeichnung anhand eines bevorzugten Ausführungsbeispiels näher erläutert. Dabei zeigt Hereinafter, the present invention will be described with reference to the accompanying Drawing explained in more detail using a preferred embodiment. It shows  

Fig. 1 eine Querschnittsansicht eines wesentlichen Abschnitts des bevorzugten Ausführungsbeispiels der vorliegenden Erfindung, Fig. 1 is a cross-sectional view of an essential portion of the preferred embodiment of the present invention,

Fig. 3 eine schematische Darstellung einer weiteren bekannten Antriebsvorrichtung nach dem Stand der Technik. Fig. 3 is a schematic representation of another known drive device according to the prior art.

In Fig. 1 sind die den in Fig. 2 und Fig. 3 gezeigten Teilen entsprechenden Teile mit denselben Bezugszeichen versehen, so daß ergänzend auf die Beschreibung dieser Teile zu Fig. 2 und Fig. 3 verwiesen werden kann.In Fig. 1 which are provided to the parts in Fig. 2 and Fig. 3 corresponding parts shown with the same reference numerals, so that reference may be made in addition to the description of these parts to Fig. 2 and Fig. 3.

In Fig. 1 ist eine Antriebswelle 2 eines (in Fig. 2 und Fig. 3 gezeigten) Antriebsaggregats 1, insbesondere eine Kurbelwelle eines Verbrennungsmotors eines Kraftfahrzeugs, dargestellt, welche zur Übertragung eines Antriebsdrehmoments über eine Getriebeeingangswelle 7 auf ein nachgeschaltetes (und ebenfalls lediglich in Fig. 2 und Fig. 3 gezeigtes) Getriebe 9 dient. Die Getriebeeingangswelle 7 ist in der sogenannten Getriebeglocke 12 des Getriebes gelagert. Die Getriebeglocke 12 dient gemäß Fig. 1 zudem zur Aufnahme einer Getriebekupplung 8 und einer elektrischen Maschine 4, die eine oder mehrere ortsfeste Statorwicklungen 5 und einen oder mehrere drehbare Rotoren 6 umfaßt. Jeder Rotor 6 kann wicklungslos oder mit Rotorwicklungen ausgestaltet sein. Bei dem in Fig. 1 gezeigten Ausführungsbeispiel umfaßt die elektrische Maschine 4 drei Statorwicklungen 5 sowie drei Rotorwicklungen 6, die somit ein dreistufiges Rotor-Stator-System bilden.In Fig. 1 is a drive shaft 2 of a drive unit 1 (in FIG. 2 and FIG shown. 3), in particular a crankshaft of an internal combustion engine of a motor vehicle, shown, which for the transmission of drive torque through a transmission input shaft 7 to a downstream (and also only in Fig. 2 and Fig. 3) gear 9 is used. The transmission input shaft 7 is mounted in the so-called transmission bell 12 of the transmission. The bell housing 12 is shown in FIG. 1 also for receiving a transmission clutch 8 and an electric machine 4, which comprises one or a plurality of stationary stator windings 5, and one or a plurality of rotatable rotors 6. Each rotor 6 can be configured without windings or with rotor windings. In the exemplary embodiment shown in FIG. 1, the electrical machine 4 comprises three stator windings 5 and three rotor windings 6 , which thus form a three-stage rotor-stator system.

Wie der Darstellung von Fig. 1 entnommen werden kann, ist die Getriebekupplung 8 in einem Kupplungsgehäuse 14 untergebracht. Das Kupplungsgehäuse 14 befindet sich im mittleren Bereich der Getriebeglocke und dient zudem als Träger für die Rotoren 6 der elektrischen Maschine 4, d. h. die Rotoren 6 sind außen auf dem Kupplungsgehäuse 14 angebracht, während die Statorwicklungen 5 ortsfest an der Innenwand der Getriebeglocke 12 befestigt sind. Die elektrische Maschine 4 ist somit im äußeren Ringraum der Getriebeglocke 12 angeordnet, so daß die elektrische Maschine 4 mit einem maximalen Hebelarm bzw. einem größtmöglichen Spulen-Ringvolumen wirken kann. As can be seen from the illustration in FIG. 1, the transmission clutch 8 is accommodated in a clutch housing 14 . The clutch housing 14 is located in the central region of the transmission bell and also serves as a carrier for the rotors 6 of the electrical machine 4 , ie the rotors 6 are mounted on the outside of the clutch housing 14 , while the stator windings 5 are fixed in place on the inner wall of the transmission bell 12 . The electrical machine 4 is thus arranged in the outer annular space of the transmission bell 12 , so that the electrical machine 4 can act with a maximum lever arm or the largest possible coil ring volume.

Anstelle einer üblichen Einscheibenkupplung mit einem großen Durchmesser wird gemäß Fig. 1 eine innerhalb des Rotors 6 der elektrischen Maschine 4 angeordnete Mehrscheibenkupplung verwendet, die sowohl als Trockenkupplung als auch - bei geschlossenem Kupplungsgehäuse 14 - als Naßkupplung im Ölbad ausgeführt sein kann.Instead of a conventional single disc clutch having a large diameter 1 shows a arranged inside of the rotor 6 of the electric machine 4 multi-plate clutch is used according to which both a dry clutch as well as -. Can be configured as multiple disc clutch in an oil bath - in the closed clutch housing 14.

Die einzelnen Stufen des mehrstufigen Rotor-Stator-Systems der elektrischen Maschine 4 können zwischen einer Reihen- oder Parallelschaltung umgeschaltet werden. Vorteilhafterweise sind die einzelnen Rotor-Stator-Stufen der elektrischen Maschine 4 jeweils mit einer Ausgangsspannung von 12 V zur Versorgung eines 36 V (42 V)- Bordnetzes ausgelegt.The individual stages of the multi-stage rotor-stator system of the electrical machine 4 can be switched between a series or parallel connection. The individual rotor-stator stages of the electrical machine 4 are advantageously each designed with an output voltage of 12 V for supplying a 36 V (42 V) electrical system.

Die elektrische Maschine 4 kann wie ein eingangs beschriebenes Starter/Generator- System betrieben bzw. verwendet werden, so daß diesbezüglich auf die vorhergehenden Erläuterungen verwiesen wird, um Wiederholungen zu vermeiden.The electrical machine 4 can be operated or used like a starter / generator system described at the outset, so that reference is made to the above explanations in this regard in order to avoid repetitions.

Bei Antriebsvorrichtungen der gattungsgemäßen Art stellen die bei Rotation der Antriebs- oder Kurbelwelle 2 auftretenden Antriebswellen-Drehschwingungen ein besonderes Problem dar, da diese sich bei Verwendung der Antriebsvorrichtung in einem Kraftfahrzeug über einzelne Fahrzeugkomponenten fortpflanzen können und somit für die Fahrzeuginsassen einen störenden Geräusch- und Vibrationspegel darstellen. Zur Bedämpfung dieser Drehschwingungen werden bekannterweise im Antriebsstrang der Antriebsvorrichtung Drehschwingungsdämpfer verwendet, wobei beispielsweise der Einsatz eines Schwungrads oder eines sogenannten Drehschwingungstilgers möglich ist.In the case of drive devices of the generic type, the drive shaft torsional vibrations which occur when the drive or crankshaft 2 rotates represent a particular problem, since when the drive device is used in a motor vehicle these can propagate over individual vehicle components and thus cause a disturbing noise and vibration level for the vehicle occupants represent. To dampen these torsional vibrations, torsional vibration dampers are known to be used in the drive train of the drive device, it being possible, for example, to use a flywheel or a so-called torsional vibration damper.

Dies trifft auch auf die vorliegende Erfindung zu. So ist gemäß Fig. 1 zur Drehschwingungsbedämpfung ein Schwungrad 15, daß auch als Zweimassenschwungrad ausgebildet werden kann, im Kupplungsgehäuse 14 angeordnet. Das Schwungrad 15 besitzt vorzugsweise denselben Durchmesser wie die Getriebeglocke 12. Ebenso kann das Schwungrad 15 auch im Kupplungsgehäuse 14, dann jedoch mit einem geringeren Wirkdurchmesser, eingesetzt oder ein Schwungrad mit einem drehzahladaptiven Tilger zur Anwendung kommen.This also applies to the present invention. 1 as is shown in FIG. Drehschwingungsbedämpfung to a flywheel 15 that can be configured as a dual-mass flywheel, arranged in the clutch housing 14. The flywheel 15 preferably has the same diameter as the transmission bell 12 . Likewise, the flywheel 15 can also be used in the clutch housing 14 , but then with a smaller effective diameter, or a flywheel with a speed-adaptive damper can be used.

Die Rotoren 6 der elektrischen Maschine 4 können fest auf das Kupplungsgehäuse 14 aufgesetzt sein. Die feste Anordnung der Rotoren 6 auf dem Kupplungsgehäuse 14 kann jedoch bedingt aufgehoben werden, um eine die Antriebswellen-Drehschwingungen bedämpfende Wirkung ähnlich einem Zwei-Massen-Schwungrad oder einem Drehschwingungstilger zu erzielen. Hierzu wird zwischen zwei Anschlägen in einem gewissen Umfang eine Verdrehung zwischen den Rotoren 6 und dem Kupplungsgehäuse 14 zugelassen, wobei die Verdrehung durch definierte Reibmomente oder auch durch (in Fig. 1 nicht gezeigte) elastische Spannelemente zwischen den Rotoren 6 und dem Kupplungsgehäuse 14 im Sinne einer Drehschwingungsbedämpfung beeinflußt wird. Durch diese Maßnahmen sind keine separaten Tilger oder Zwei-Massen- Schwungräder erforderlich.The rotors 6 of the electrical machine 4 can be firmly attached to the clutch housing 14 . The fixed arrangement of the rotors 6 on the clutch housing 14 can, however, be canceled in order to achieve a damping effect on the drive shaft torsional vibrations, similar to a two-mass flywheel or a torsional vibration damper. For this purpose, a twist between the rotors 6 and the clutch housing 14 is permitted to a certain extent between two stops, the twist in the sense by defined frictional moments or also by elastic tensioning elements (not shown in FIG. 1) between the rotors 6 and the clutch housing 14 a torsional vibration damping is affected. These measures do not require separate absorbers or dual mass flywheels.

Sind, wie in Fig. 1 gezeigt, mehrere Rotoren 6 vorgesehen, kann es vorteilhaft sein, die Rotoren mit unterschiedlichen Drehmassen auszugestalten und/oder für die Rotoren 6 unterschiedliche Elastizitäten der entsprechenden Spannelemente oder unterschiedliche Reibverspannungen vorzusehen, um die Drehschwingungsbedämpfung weiter zu verbessern.If, as shown in FIG. 1, a plurality of rotors 6 are provided, it may be advantageous to design the rotors with different rotational masses and / or to provide different elasticities of the corresponding clamping elements or different frictional stresses for the rotors 6 in order to further improve the torsional vibration damping.
