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 electric machine according to the preamble of claim 1. In particular, the present invention relates to a drive device for a motor vehicle, which has a configured in the form of a starter / generator system electric 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 arranged between a drive motor, usually an internal combustion engine, and a transmission of the motor vehicle. Such starter / generator systems allow, on the one hand, easier starting of the drive motor and, on the other hand, high generator power in order to provide energy for specific consumers of the motor vehicle.

Der grundsätzliche Aufbau von Antriebsvorrichtungen mit Starter/Generator-Systemen ist in 2 dargestellt und kann beispielsweise den Druckschriften WO 98/05 882 A1 oder DE 196 16 504 A1 entnommen werden. Dabei zeigt 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 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 in 2 shown and may, for example, the publications WO 98/05882 A1 or DE 196 16 504 A1 be removed. It shows 2 the drive train of a motor vehicle, wherein as a drive unit, an internal combustion engine 1 is used. The crankshaft 2 of the internal combustion engine is via a separating clutch 3 with an electric machine serving as a starter / generator system 4 connected, which is a rotor 6 and one the rotor 6 surrounding stator 5 includes. The windings of the stator 5 are connected to the motor vehicle battery and electrical consumers of the motor vehicle, resulting in 2 generally by the one with the stator 5 connected electrical system 11 of the motor vehicle is indicated. The rotor 6 the electric machine 4 is the output side via a gear coupling 8th with the transmission input shaft 7 a gearbox 9 in connection, via which the drive torque to the drive wheels 10 of the motor vehicle is transmitted.

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 used as a starter / generator system 4 is operated in two different operating modes. In an engine operation takes over the electric machine 4 when operating the starter key the function of a starter or engine to start the engine 1 , For this purpose, the stator windings 5 corresponding excitation currents supplied in such a way that the rotor 6 is applied with a starting torque, which is the starting of the internal combustion engine 1 facilitated. After starting the internal combustion engine 1 turns on the electric machine 4 in a generator mode in which the rotor 6 over the crankshaft 2 of the internal combustion engine 1 set in rotation and thus in the stator windings 5 a voltage is induced, which is used to supply energy to the electrical system 11 or the consumer connected to the motor vehicle is used.

In der WO 98/05882 A1 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 A1 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 the WO 98/05882 A1 is also proposed in the rotor 6 to integrate a vibration damping or a torsional vibration, this arrangement is configured for example in the form of a two-mass flywheel and the rotor 6 with the transmission input shaft 7 combines. Furthermore, in the WO 97/21560 A1 executed that the rotor 6 the electric machine 4 basically represents a mass moment of inertia and therefore at the same time the function of a flywheel for the internal combustion engine 1 can take over.

Zudem ist in der EP 0 724 978 A1 eine Antriebsvorrichtung offenbart. Der grundsätzliche Aufbau dieser Antriebsvorrichtung ist in 3 dargestellt und entspricht weitgehend dem in 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 selbsttätig 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, selbsttätig eingekuppelt ist. Wie der Darstellung von 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.Moreover, in the EP 0 724 978 A1 discloses a drive device. The basic structure of this drive device is in 3 represented and corresponds largely to the in 2 shown construction. 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 connected to the drive wheels of the motor vehicle transmission output shaft 13 has. The transmission input shaft 7 is via a separating clutch 8th with an electric machine 4 connected, which in turn a stationary stator 5 and a rotatable rotor 6 includes. About another torque transmission path is the transmission input shaft 7 with the crankshaft 2 an internal combustion engine 1 connected, wherein in this torque transmission path a bridgeable overrunning clutch 3 is arranged, which automatically opens during engine operation of the electric machine and thus the internal combustion engine 1 from the transmission input shaft 7 uncouples while the overrunning clutch 3 when driving the motor vehicle exclusively by the internal combustion engine 1 ie when the electric machine 4 de-energized or operates in generator mode, is automatically engaged. Like the presentation of 3 can be taken, are the electric machine 4 with the stator 5 and the rotor 6 as well as the transmission clutch 8th in a common, the transmission 9 associated housing 12 accommodated.

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, sodass 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 müssen, was insbesondere bei großen Motoren aufgrund der Motorraumenge nicht realisierbar ist.The for the start of the internal combustion engine 1 and provided as a generator for the electrical system supply electric machine acts directly without intermediate translation on the crankshaft 2 of the internal combustion engine 1 so that the electrical machine occupies a not inconsiderable volume due to the relatively large starting torques. Because the space between the internal combustion engine 1 and the transmission 9 usually only for receiving the gearbox clutch 8th or a corresponding transducer, performs the additional arrangement of an electric machine in this area inevitably to the engine 1 or the gearbox 9 have to be moved spatially, which is not feasible especially for large engines due to the Motorraumenge.

Aus der US 5 103 127 A ist eine gattungsgemäße Antriebsvorrichtung bekannt, mit einem Antriebsaggregat, mit einer elektrischen Maschine, welche mindestens einen Stator und mindestens einen auf einer mit dem Antriebsaggregat gekoppelten Antriebswelle angeordneten Rotor umfasst, und mit einer Getriebekupplung, welche ein von der Antriebswelle geliefertes Drehmoment auf ein Getriebe überträgt, wobei die elektrische Maschine und die Getriebekupplung in einem gemeinsamen Gehäuse untergebracht sind, wobei die elektrische Maschine mit dem mindestens einen Stator und dem mindestens einen Rotor in einem Zwischenraum zwischen der Innenwand des gemeinsamen Gehäuses und einem im mittleren Bereich des gemeinsamen Gehäuses angeordneten Kupplungsgehäuse der Getriebekupplung angeordnet ist.From the US 5 103 127 A a generic drive device is known, with a drive unit, with an electric machine, which comprises at least one stator and at least one arranged on a drive unit coupled to the drive shaft rotor, and with a transmission clutch, which transmits a torque supplied by the drive shaft to a transmission, wherein the electric machine and the transmission clutch are accommodated in a common housing, wherein the electric machine with the at least one stator and the at least one rotor in a space between the inner wall of the common housing and arranged in the central region of the common housing clutch housing of the transmission clutch is.

Aus der US 5 293 089 A ist eine Antriebsvorrichtung mit einer elektrischen Maschine bekannt, die mehrstufig mit mehreren Statoren und mehreren Rotoren ausgebildet ist, wobei zwischen einer Reihen- und einer Parallelschaltung der einzelnen Stufen der elektrischen Maschine umgeschaltet werden kann.From the US 5 293 089 A is a drive device with an electric machine is known, which is formed in several stages with multiple stators and multiple rotors, which can be switched between a series and a parallel connection of the individual stages of the electric machine.

Aus der EP 0 706 462 B1 ist eine Antriebsanordnung für ein mit einem Verbrennungsmotor und einer elektrischen Maschine ausgestattetes Hybridfahrzeug bekannt, wobei die Verbindung eines Rotors mit einer Abtriebswelle Torsionsschwingungsdämpfungselemente aufweist.From the EP 0 706 462 B1 For example, a drive arrangement for a hybrid vehicle equipped with an internal combustion engine and an electric machine is known, wherein the connection of a rotor to an output shaft has torsional vibration damping elements.

Aus der DE 32 33 502 A1 ist eine Antriebsvorrichtung bekannt mit einem Antriebsaggregat und einer elektrischen Maschine, welche mindestens einen Stator und mindestens einen auf einer mit dem Antriebsaggregat gekoppelten Antriebswelle angeordneten Rotor umfasst.From the DE 32 33 502 A1 a drive device is known with a drive unit and an electric machine, which comprises at least one stator and at least one rotor arranged on a drive shaft coupled to the drive unit.

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, wobei gleichzeitig eine gute Drehschwingungsbedämpfung sichergestellt ist.The present invention is therefore an object of the invention to provide a drive device with an arranged between a drive unit and a transmission of the drive device electric machine, in which the electric machine can be accommodated easily in the limited space available between the drive unit and the transmission, so that in particular no spatial displacement of the drive unit or the transmission is required, at the same time a good torsional vibration damping is ensured.

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 in claim 1. The subclaims describe preferred embodiments of the invention.

Dabei wird zwischen den Rotoren der elektrischen Maschine und dem Kupplungsgehäuse eine gewisse Verdrehung ermöglicht, welche durch definierte Reibmomente oder auch durch elastische Spannelemente zwischen den Rotoren und dem Kupplungsgehäuse im Sinne einer Drehschwingungsbedämpfung beeinflusst wird, sodass eine die Antriebswellen-Drehschwingungen des Antriebsaggregats bedämpfende Wirkung ähnlich zu einem Zwei-Massen-Schwungrad oder einem Drehschwingungstilger erzielt wird.In this case, a certain rotation is made possible between the rotors of the electric machine and the clutch housing, which is influenced by defined friction moments or by elastic clamping elements between the rotors and the clutch housing in terms of torsional vibration damping, so that the drive shaft torsional vibrations of the drive unit damping effect similar to a two-mass flywheel or a torsional vibration damper is achieved.

Die innerhalb des Rotors der elektrischen Maschine angeordnete Getriebekupplung kann sowohl als Nass- oder Trockenkupplung ausgestaltet sein. Die Getriebekupplung ist vorzugsweise eine Mehrscheibenkupplung.The arranged inside the rotor of the electric machine transmission clutch can be configured both as a wet or dry clutch. The transmission clutch is preferably a multi-plate 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 be arranged next to the electric machine or in the transmission coupling region, but then with a smaller effective diameter.

Die elektrische Maschine ist dreistufig ausgebildet, bei der jede Stufe für 12 V ausgelegt ist, um ein 36-V-Bordnetz versorgen zu können.The electrical machine is designed in three stages, with each stage being designed for 12 V in order to supply a 36 V electrical system.

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 a combustion engine is used as the drive unit, the drive torque is transmitted via a crankshaft to the rotor of the electrical machine designed as a starter / generator system and the transmission. In this case, the electric machine is, as described above, used 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 for electrical consumers of the motor vehicle. However, the present invention can basically be used wherever the problem underlying the invention is given.

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

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

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

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

In 1 ist eine Antriebswelle 2 eines (in 2 und 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 2 und 3 gezeigtes) Getriebe 9 dient. Die Getriebeeingangswelle 7 ist in der sogenannten Getriebeglocke 12 des Getriebes gelagert. Die Getriebeglocke 12 dient gemäß 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 1 gezeigten Ausführungsbeispiel umfaßt die elektrische Maschine 4 drei Statorwicklungen 5 sowie drei Rotorwicklungen 6, die somit ein dreistufiges Rotor-Stator-System bilden.In 1 is a drive shaft 2 one (in 2 and 3 shown) drive unit 1 , In particular, a crankshaft of an internal combustion engine of a motor vehicle, shown, which for transmitting a driving torque via a transmission input shaft 7 on a downstream (and also only in 2 and 3 shown) transmission 9 serves. The transmission input shaft 7 is in the so-called gear bell 12 stored the transmission. The gear bell 12 serves according to 1 also for receiving a gear coupling 8th and an electric machine 4 containing one or more stationary stator windings 5 and one or more rotatable rotors 6 includes. Every rotor 6 can be designed without a winding or with rotor windings. At the in 1 embodiment shown comprises the electric machine 4 three stator windings 5 as well as three rotor windings 6 , which thus form a three-stage rotor-stator system.

Wie der Darstellung von 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.Like the presentation of 1 can be removed, is the transmission clutch 8th in a clutch housing 14 accommodated. The coupling housing 14 is located in the middle area of the bell housing and also serves as a carrier for the rotors 6 the electric machine 4 ie the rotors 6 are outside on the clutch housing 14 attached while the stator windings 5 stationary on the inner wall of the bell housing 12 are attached. The electric machine 4 is thus in the outer annulus of the bell housing 12 arranged so that the electric machine 4 can act with a maximum lever arm or a maximum coil ring volume.

Anstelle einer üblichen Einscheibenkupplung mit einem großen Durchmesser wird gemäß 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 with a large diameter is according to 1 one inside the rotor 6 the electric machine 4 arranged multi-disc clutch used both as a dry clutch and - with closed clutch housing 14 - Can be designed as a wet clutch in an oil bath.

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 electric machine 4 can be switched between a series or parallel connection. Advantageously, the individual rotor-stator stages of the electric machine 4 each with an output voltage of 12 V designed to power a 36 V (42 V) board network.

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 electric machine 4 can be operated or used as a starter / generator system described above, so that reference is made in this regard to the previous explanations in order to avoid repetition.

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 drive devices of the generic type provide during rotation of the drive or crankshaft 2 occurring drive shaft torsional vibrations is a particular problem, since they can propagate when using the drive device in a motor vehicle about individual vehicle components and thus represent a disturbing noise and vibration levels for the vehicle occupants. To dampen these torsional vibrations are known to be used in the drive train of the drive device torsional vibration damper, for example, the use of a flywheel or a so-called torsional vibration damper is possible.

Dies trifft auch auf die vorliegende Erfindung zu. So ist gemäß 1 zur Drehschwingungsbedämpfung ein Schwungrad 15, das 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. So is according to 1 for torsional vibration damping a flywheel 15 , which can also be designed as a dual mass flywheel, in the clutch housing 14 arranged. The flywheel 15 preferably has the same diameter as the bell housing 12 , Likewise, the flywheel 15 also in the clutch housing 14 , but then used with a smaller effective diameter, or used a flywheel with a speed-adaptive absorber.

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 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 the electric machine 4 Can be tight on the clutch housing 14 be set up. The fixed arrangement of the rotors 6 on the clutch housing 14 However, it can be canceled conditionally to achieve a drive shaft torsional vibration damping effect similar to a two-mass flywheel or a torsional vibration damper. To this end, between two stops to a certain extent a rotation between the rotors 6 and the clutch housing 14 admitted, wherein the rotation by defined friction moments or by (in 1 not shown) elastic clamping elements between the rotors 6 and the clutch housing 14 is influenced in the sense of a torsional vibration damping. These measures do not require separate absorbers or dual mass flywheels.
