Description
Die Erfindung bezieht sich auf ein elektromechanisches Radantriebssystem für ein Kraftfahrzeug das als solches dazu dient, ein mit einer Hauptantriebseinrichtung, beispielsweise einer Brennkraftmaschine ausgestattetes Kraftfahrzeug im unteren Geschwindigkeitsbereich temporär elektromotorisch zu betreiben.The invention relates to an electromechanical wheel drive system for a motor vehicle which serves as such to temporarily operate a motor vehicle equipped with a main drive device, for example an internal combustion engine, in the lower speed range.
Der Erfindung liegt die Aufgabe zugrunde, ein elektromechanisches Radantriebssystem der eingangs genannten Art zu schaffen, das sich durch eine hohe Funktionszuverlässigkeit und ein vorteilhaftes mechanisches Betriebsverhalten auszeichnet.The invention has for its object to provide an electromechanical wheel drive system of the type mentioned, which is characterized by a high functional reliability and an advantageous mechanical performance.
Die vorgenannte Aufgabe wird erfindungsgemäß gelöst durch ein Radantriebssystem für ein Kraftfahrzeug, mit:
- – einer Eingangswelle,
- – einer Radantriebswelle,
- – einer Schalteinrichtung zur selektiven Koppelung der Eingangswelle mit der Radantriebswelle,
- – einem ersten Elektromotor mit einem ersten Läufer zur temporären Einbringung eines ersten Radantriebsbeitrags in die Radantriebswelle, und
- – einem zweiten Elektromotor mit einem zweiten Läufer zur temporären Einbringung eines zweiten Radantriebsbeitrags ebenfalls in die Radantriebswelle,
- – wobei die Schalteinrichtung derart ausgebildet ist, dass der Schaltzustand der Schalteinrichtung nach Maßgabe einer Relativdrehung zwischen dem Läufer des ersten Elektromotors und dem Läufer des zweiten Elektromotors einstellbar ist.
- An input shaft,
- A wheel drive shaft,
- A switching device for selectively coupling the input shaft to the wheel drive shaft,
- A first electric motor having a first rotor for temporary introduction of a first wheel drive contribution into the wheel drive shaft, and
- A second electric motor with a second rotor for the temporary introduction of a second wheel drive contribution also into the wheel drive shaft,
- - Wherein the switching device is designed such that the switching state of the switching device is adjustable in accordance with a relative rotation between the rotor of the first electric motor and the rotor of the second electric motor.
Dadurch wird es auf vorteilhafte Weise möglich, das zur Bewerkstelligung des elektrischen Radantriebs erforderliche Drehmoment durch zwei kinematisch parallel geschaltete Motoren zu generieren und durch eine steuerungstechnisch vorteilhaft aktiv einstellbare Drehwinkeldifferenz zwischen den beiden umlaufenden Rotoren ein Koppelglied zu betätigen das eine selektive Auftrennung bzw. Schließung des die Eingangswelle und die Radantriebswelle umfassenden Radantriebsstranges ermöglicht. Die Erfindung findet Anwendung bei Kraftfahrzeugen und ermöglicht einen elektrischen Zusatzantrieb insbesondere für den unteren Geschwindigkeitsbereich. Während des elektrischen Fahrens wird über das Koppelglied der verbrennungsmotorische Antriebsstrang relativ nahe am Rad abgekoppelt. Durch dieses Konzept werden während der Phase des elektromotorischen Antriebs die hierbei anfallenden Systemreibungsverluste gegenüber herkömmlichen Konzepten bei welchen der Radantriebsstrang geschleppt wird, reduziert.This makes it possible in an advantageous manner, to generate the required for the achievement of the electric wheel drive torque by two kinematic parallel motors and actuate a control element advantageously actively adjustable rotation angle difference between the two rotating rotors a coupling member to a selective separation or closure of the Input shaft and the wheel drive shaft comprehensive Radantriebsstranges allows. The invention finds application in motor vehicles and allows an electric auxiliary drive, in particular for the lower speed range. During electric driving, the internal combustion engine drive train is decoupled relatively close to the wheel via the coupling member. As a result of this concept, the system friction losses occurring during the phase of the electromotive drive are reduced compared to conventional concepts in which the wheel drive train is towed.
Die beiden Elektromotoren sind vorzugsweise konzentrisch um die Eingangswelle des Radantriebsstranges herum angeordnet. Die beiden Elektromotoren können dabei radial ineinander geschachtelt oder alternativ hierzu auch axial in Reihe angeordnet werden. Die beiden Elektromotoren sind vorzugsweise als sog. Drehfeldmotoren ausgebildet deren Rotoren schlupffrei dem statorseitig generierten Drehfeld folgen. Die Rotoren können hierbei mit Permanentmagneten bestückt sein. Alternativ kann das erfindungsgemäße Konzept jedoch auch mit hiervon abweichenden Motorbauformen umgesetzt werden.The two electric motors are preferably arranged concentrically around the input shaft of the wheel drive train. The two electric motors can be nested radially in one another or alternatively arranged axially in series. The two electric motors are preferably designed as so-called. Rotary field motors whose rotors slip-free follow the stator generated rotation field. The rotors can be equipped with permanent magnets. Alternatively, however, the concept according to the invention can also be implemented with deviating engine designs.
Gemäß einem besonderen Aspekt der vorliegenden Erfindung sind die beiden Elektromotoren derart ausgelegt, dass diese bei entsprechender Ansteuerung in etwa gleiche Leistungsbeiträge leisten können. Vorzugsweise sind die beiden Elektromotoren so verbaut, dass deren Statoren gehäuseseitig festgelegt sind.According to a particular aspect of the present invention, the two electric motors are designed such that they can make approximately the same power contributions with appropriate control. Preferably, the two electric motors are installed so that their stators are fixed on the housing side.
Die Antriebseinrichtung kann gemäß einer besonders bevorzugten Ausführungsform so ausgebildet sein, dass das Gehäuse derselben auf der Eingangswelle und der mit dieser achsgleichen Radantriebswelle sitzt und eine Drehmomentenabstützung an einer benachbarten Komponente, z.B. an einem benachbarten Getriebe oder der Karosserie oder am Radträger erhält. Diese Drehmomentenabstützung kann insbesondere über Hebel- oder Armelemente erfolgen die derart gelenkig mit der Radaufhängung oder der Karosserie gekoppelt sind, dass das Gehäuse der Antriebseinrichtung neben der Drehmomentenabstützung eine hinreichende Bewegungsfreiheit erlangt. Die entsprechenden Gelenkstellen können insbesondere Kugelgelenke oder elastische Gelenkbuchsen umfassen. Das Gehäuse selbst wird vorzugsweise als Leichtbauteil, vorzugsweise aus einem Aluminiumwerkstoff gefertigt, so dass die Antriebseinrichtung selbst ein möglichst geringes Eigengewicht erhält. Gemäß einem weiteren Aspekt der vorliegenden Erfindung kann die Antriebseinrichtung so aufgebaut werden, dass der Rotor des ersten Elektromotors im Gehäuse, insbesondere im ersten Stator gelagert ist. Der zweite Rotor wird dann vorzugsweise im ersten Rotor gelagert. Da die beiden Rotoren im Regelbetrieb letztlich synchron laufen und damit die entsprechende Lagerung nur die im Rahmen des Stellvorganges zwischen den Rotoren auftretenden Relativdrehzahlen ertragen muss führt dieser Ansatz zu einer signifikanten Reduktion der Lagerbelastung.According to a particularly preferred embodiment, the drive device can be designed such that the housing thereof is seated on the input shaft and the wheel drive shaft which is the same axis, and a torque support is provided on an adjacent component, e.g. receives on a neighboring transmission or the body or on the wheel. This torque support can be carried out in particular via lever or arm elements which are coupled so articulated to the suspension or the body, that the housing of the drive device in addition to the torque support obtains sufficient freedom of movement. The corresponding hinge points may in particular comprise ball joints or elastic joint bushes. The housing itself is preferably made as a lightweight component, preferably made of an aluminum material, so that the drive device itself receives the lowest possible weight. According to a further aspect of the present invention, the drive device can be constructed such that the rotor of the first electric motor is mounted in the housing, in particular in the first stator. The second rotor is then preferably stored in the first rotor. Since the two rotors ultimately run synchronously during normal operation and thus the corresponding bearing only has to endure the relative rotational speeds occurring between the rotors as part of the positioning process, this approach leads to a significant reduction of the bearing load.
Das bereits genannte, zur Koppelung der Leistungsbeiträge der beiden Elektromotoren vorgesehene Summiergetriebe, ist vorzugsweise als Planetengetriebe ausgeführt, um die beiden Rotoren zu koppeln. Dabei kann beispielsweise der Rotor des ersten Motors ein Sonnenrad des Summiergetriebes und der Rotor des zweiten Elektromotors das Hohlrad des Summiergetriebes antreiben.The already mentioned, provided for coupling the power contributions of the two electric motors summing gear is preferably designed as a planetary gear to couple the two rotors. In this case, for example, the rotor of the first motor, a sun gear of the summation and the rotor of the second electric motor drive the ring gear of the summation.
Die Antriebseinrichtung kann gemäß einer besonders bevorzugten Ausführungsform der Erfindung so ausgebildet sein, dass der Planetenträger des Summiergetriebes mit dem Leistungseingang eines folgenden Übersetzungsgetriebes gekoppelt ist. Das Übersetzungsgetriebe kann dabei als Umlaufrädergetriebe ausgeführt sein. Alternativ hierzu sind auch andere, vorzugsweise hoch übersetzende Getriebe (z.B. Harmonic Drive-Getriebe, oder anderweitige Exzentergetriebe „Intermeshing Planetary Gears“) einsetzbar. The drive device can be designed according to a particularly preferred embodiment of the invention so that the planet carrier of the summing gear is coupled to the power input of a following transmission gear. The transmission gear can be designed as a planetary gear. Alternatively, other, preferably high-ratio transmission (eg Harmonic Drive gearbox, or other eccentric "Intermeshing Planetary Gears") can be used.
Die kinematische Einbindung der erfindungsgemäßen Antriebseinrichtung in das Antriebssystem des Kraftfahrzeuges erfolgt vorzugsweise indem ein Koppelelement der Schalteinrichtung den Ausgang des Übersetzungsgetriebes selektiv mit dem Antriebsstrang koppelt und zugleich die Auftrennung oder Schließung des Antriebsstranges bewirkt. Das Koppelelement dient damit sowohl der selektiven Verbindung oder Abkoppelung des elektrischen Antriebssystems vom radseitigen Antriebsstrangabschnitt als auch der Auftrennung des Hauptantriebsstranges.The kinematic integration of the drive device according to the invention in the drive system of the motor vehicle is preferably carried out by a coupling element of the switching device selectively couples the output of the transmission with the drive train and at the same time causes the separation or closure of the drive train. The coupling element thus serves both the selective connection or decoupling of the electric drive system from the wheel-side drive train section and the separation of the main drive train.
Die erfindungsgemäße Antriebseinrichtung kann so ausgelegt sein, dass die E-Motoren selektiv mit der Antriebswelle bzw. dem Rad koppelbar sind. Das Koppelelement ist dabei vorzugsweise in die folgenden drei funktional unterschiedliche Schaltstellungen verbringbar: 1. Koppelung der Eingangswelle mit der Radantriebswelle wobei der E-Antrieb entkoppelt ist, 2. Koppelung der Eingangswelle mit der Radantriebswelle sowie Koppelung von E-Antrieb mit der Radantriebswelle, 3. Koppelung Elektromotoren mit der Radantriebswelle wobei die Eingangswelle entkoppelt ist.The drive device according to the invention can be designed so that the electric motors can be selectively coupled to the drive shaft or the wheel. The coupling element is preferably brought into the following three functionally different switching positions: 1. Coupling of the input shaft with the wheel drive shaft wherein the electric drive is decoupled, 2. Coupling of the input shaft with the wheel drive shaft and coupling of electric drive with the wheel drive shaft, 3rd Coupling electric motors with the wheel drive shaft with the input shaft is decoupled.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung ist das Koppelelement als Schiebemuffe ausgeführt. Alternativ hierzu ist es auch möglich, das Koppelelement als Teil einer Klauenkupplung zu fertigen. Bei einer Ausführung des Koppelelements als Schiebemuffe kann diese so ausgebildet sein, dass die Verzahnungen an der Schiebemuffe axial durch Umfangsnuten gegliedert ist. Hierdurch wird es möglich eine Mechanik zu schaffen, bei welcher der zur Erreichung der einzelnen Schaltstellungen erforderliche Verschiebeweg verkürzt wird.According to a particularly preferred embodiment of the invention, the coupling element is designed as a sliding sleeve. Alternatively, it is also possible to manufacture the coupling element as part of a dog clutch. In one embodiment of the coupling element as a sliding sleeve, this can be designed so that the teeth on the sliding sleeve is divided axially by circumferential grooves. This makes it possible to provide a mechanism in which the required to achieve the individual switching positions displacement is shortened.
Die Betätigung des Koppelelementes erfolgt wie bereits ausgeführt durch Herbeiführen einer Drehwinkeldifferenz zwischen den Rotoren der beiden Elektromotoren. Die Betätigungsmechanik kann dabei konstruktiv so ausgeführt sein, dass die Planeten des Summiergetriebes eine Spindel besitzen, über die ein Stellglied axial verschiebbar ist. Nach Maßgabe der Drehwinkeldifferenz zwischen den beiden Rotoren der beiden Elektromotoren wird das Stellglied axial verschoben. Das Stellglied betätigt dann das Koppelelement und bringt dieses in die gewünschten Wirkstellungen.The actuation of the coupling element is carried out as already stated by inducing a rotational angle difference between the rotors of the two electric motors. The actuating mechanism can be constructively designed so that the planet of the summing have a spindle through which an actuator is axially displaceable. In accordance with the rotational angle difference between the two rotors of the two electric motors, the actuator is displaced axially. The actuator then actuates the coupling element and brings this into the desired action positions.
Die erfindungsgemäße Antriebseinheit kann an der Vorder- oder der Hinterachse eingesetzt werden. Der Hauptantrieb des Kraftfahrzeuges kann über einen Verbrennungsmotor erfolgen. Die erfindungsgemäße Antriebseinrichtung kann weiterhin auch an der nicht über den Hauptantriebsstrang angetriebenen Fahrzeugachse sitzen und damit einen Zusatzantrieb für ansonsten nicht angetriebene Räder bilden. Über die erfindungsgemäße Mechanik können dann selektiv die Elektromotoren zugeschaltet oder vom zugeordneten Rad entkoppelt werden.The drive unit according to the invention can be used on the front or the rear axle. The main drive of the motor vehicle can take place via an internal combustion engine. The drive device according to the invention can furthermore also be seated on the vehicle axle which is not driven via the main drive train and thus form an additional drive for otherwise non-driven wheels. By means of the mechanism according to the invention, the electric motors can then be selectively switched on or decoupled from the assigned wheel.
Durch die erfindungsgemäße Antriebseinrichtung ist es gemäß einem weiteren Aspekt der vorliegenden Erfindung möglich ein „Allrad-Kraftfahrzeug“ zu schaffen, bei welchem im unteren Geschwindigkeitsbereich temporär alle Fahrzeugachsen angetrieben werden. Der Antrieb einer Fahrzeugachse (z.B. der Vorderachse) erfolgt dann über den beispielsweise verbrennungsmotorisch angetriebenen Hauptantriebsstrang und der Antrieb der weiteren Fahrzeugachse erfolgt dann über die erfindungsgemäße, selektiv abkoppelbare elektromechanische Antriebseinrichtung. Die elektromechanische Antriebseinrichtung wird dann vorzugsweise bei Erreichen einer bestimmten Geschwindigkeit, oder z.B. beim Wechsel aus dem ersten Gang deaktiviert und abgekoppelt.By means of the drive device according to the invention, according to a further aspect of the present invention, it is possible to create an "all-wheel drive motor vehicle" in which all vehicle axles are temporarily driven in the lower speed range. The drive of a vehicle axle (for example the front axle) then takes place via the main drive train driven by an internal combustion engine, for example, and the drive of the further vehicle axle then takes place via the electromechanical drive device according to the invention which can be selectively disconnected. The electromechanical drive device is then preferably at a certain speed, or e.g. deactivated and disconnected when changing from first gear.
Die Schalteinrichtung kann weiterhin so aufgebaut werden, dass diese bei Eintritt eines Schubbetriebs, oder bei Erreichen eines bestimmten Schubmomentes selbsttätig öffnet und dabei den elektromotorischen Antrieb vom Radantriebsstrang trennt. Dies kann erreicht werden, indem die Koppelungseinrichtung so ausgebildet wird, dass diese auch die Funktion einer Überlastkupplung bietet. In einer weiteren Ausführungsform wird im Schubbetrieb auf das selbsttätige Öffnen verzichtet und stattdessen die Elektromotoren im Rekuperationsmodus betrieben.The switching device can also be constructed so that it automatically opens when a pushing operation, or upon reaching a certain thrust torque and thereby separates the electric motor drive from the wheel drive train. This can be achieved by designing the coupling device such that it also provides the function of an overload clutch. In a further embodiment, the automatic opening is dispensed with in overrun mode and instead the electric motors are operated in the recuperation mode.
Die Positionierung des Koppelelements der Koppelungseinrichtung wird vorzugsweise durch Rast- oder Schnappmechaniken derart unterstützt, dass eine eingestellte Schaltstellung präzise eingehalten und erst nach Überwindung von Mindeststellkräften verändert wird. Durch dieses Konzept wird es möglich unvorhergesehene Schaltzustandsänderungen zu vermeiden.The positioning of the coupling element of the coupling device is preferably supported by latching or snap mechanisms such that a set switching position is precisely maintained and changed only after overcoming minimum forces. This concept makes it possible to avoid unforeseen switching state changes.
Das Einrücken des Koppelglieds kann unter signaltechnischer Überwachung der Relativdrehzahlen der zu koppelnden Antriebsstrangabschnitte erfolgen, so dass ein Einrücken erst oder nur dann veranlasst wird, wenn ein hinreichender Gleichlauf gegeben ist. Durch entsprechende Ansteuerung der Elektromotoren ist es auch möglich einen Gleichlaufzustand herbeizuführen der einen im wesentlichen lastfreien Schaltzustandswechsel ermöglicht.The engagement of the coupling member can be carried out under signal technical monitoring of the relative speeds of the drive train sections to be coupled, so that an engagement is only or only then initiated when a sufficient synchronization given is. By appropriate control of the electric motors, it is also possible to bring about a synchronizing state which allows a substantially load-free switching state change.
Die Elektromotoreneinheit kann grundsätzlich an der Vorder- oder Hinterachse eingebaut werden. Die Erfindung ist auch nicht beschränkt auf die verbrennungsmotorisch angetriebene Achse, sondern kann auch an der nicht angetriebenen Achse eingebaut werden. Für diesen Fall entfällt die Abkoppelung des Antriebsstrangs im elektromotorischen Betrieb. Die Einheit muss auch nicht mehr um die Eingangswelle herum angeordnet werden, sondern ist anstatt dieser eingebaut.The electric motor unit can basically be installed on the front or rear axle. The invention is not limited to the internal combustion engine driven axle, but can also be installed on the non-driven axle. In this case, the decoupling of the drive train in electromotive operation is eliminated. The unit no longer has to be arranged around the input shaft, but is installed instead.
Das erfindungsgemäße Konzept besteht im Kern in einer elektromechanischen Antriebseinheit die bei welcher in einem Gehäuse derselben zwei separat ansteuerbare Elektromotoren aufgenommen sind, wobei durch Herbeiführung einer Drehwinkeldifferenz zwischen den Rotoren der beiden Elektromotoren eine Kopplungsmechanik betätigt werden kann. Diese Kopplungsmechanik kann so ausgelegt sein, dass diese eine selektive Auftrennung eines Hautpantriebsstranges und die Ankoppelung der Elektromotoreneinheit an den radseitigen Antriebsstrangabschnitt bewerkstelligt. Die Koppelungsmechanik kann auch so ausgelegt sein, dass diese lediglich eine selektive An- oder Abkoppelung der Elektromotoreneinheit an eine zu Rad führende Radantriebswelle bewirkt. Dieser spezielle Ansatz ermöglicht es, bei einem Fahrzeug mit einer über eine Brennkraftmaschine angetriebenen Fahrzeugachse eine weitere Achse „rein elektrisch“ anzutreiben, wobei der Elektroantrieb durch Ansteuerung seiner Antriebsmotoren an- oder abgekoppelt werden kann.The concept according to the invention consists essentially in an electromechanical drive unit which is accommodated in a housing of the same two separately controllable electric motors, wherein a coupling mechanism can be actuated by inducing a rotational angle difference between the rotors of the two electric motors. This coupling mechanism can be designed so that it accomplishes a selective separation of a Hautpantriebtriebsstranges and the coupling of the electric motor unit to the wheel-side drive train section. The coupling mechanism can also be designed so that it causes only a selective connection or disconnection of the electric motor unit to a leading wheel to wheel drive shaft. This special approach makes it possible to drive a further axis "purely electrically" in a vehicle having a vehicle axle driven via an internal combustion engine, wherein the electric drive can be connected or disconnected by driving its drive motors.
Die erfindungsgemäße Antriebseinrichtung ist vorzugsweise so ausgebildet, dass diese derart schwenkbar in das Fahrzeug eingebunden ist, dass diese der Schwenkbewegung der Radantriebswelle folgen kann und lediglich eine zur Aufbringung des Antriebsmomentes erforderliche Drehmomentenabstützung erhält.The drive device according to the invention is preferably designed so that it is so pivotally integrated into the vehicle that it can follow the pivoting movement of the wheel drive shaft and receives only one required for applying the drive torque torque support.
Die erfindungsgemäße Antriebseinrichtung kann insbesondere bei einem Fahrzeug mit einer über ein Hinterachsdifferential angetriebenen Hinterachse kinematisch auch zwischen jenem Hinterachsdifferential und dem Fahrzeuggetriebe sitzen. Die erfindungsgemäße Antriebseinrichtung ermöglicht dann auch eine Auftrennung des Hauptantriebsstranges und nutzt dann jedoch weiterhin das Hinterachsdifferential zu Leistungsverzweigung. Der elektrischen Antrieb beider Hinterräder erfordert dann lediglich eine erfindungsgemäße Antriebseinheit.The drive device according to the invention can, in particular in a vehicle with a rear axle driven via a rear axle kinematically, also sit between that rear axle differential and the vehicle transmission. The drive device according to the invention then also allows a separation of the main drive train and then still uses the rear differential to power split. The electric drive of both rear wheels then only requires a drive unit according to the invention.
Ansonsten kann bei einem hinterachsgetriebenen Fahrzeug das erfindungsgemäße Antriebskonzept umgesetzt werden, indem im Leistungsfluss nach dem Hinterachsdifferential liegenden Bereich zwei erfindungsgemäße Antriebseinheiten verbaut werden die als solche eine selektive Auftrennung der zwischen dem Differential und den beiden Fahrzeugrädern liegenden Wellensysteme ermöglichen- und dann eben eine elektrische Einleitung jeweils eines Antriebsmomentes in die jeweilige Radantriebswelle ermöglichen.Otherwise, in a rear axle-driven vehicle, the drive concept according to the invention can be implemented by two drive units according to the invention are installed in the power flow to the rear axle differential which allow as such a selective separation of lying between the differential and the two vehicle wheels shaft systems - and then just an electrical introduction each allow a drive torque in the respective wheel drive shaft.

Bei den vorangehend beschriebenen Ausführungsbeispielen erfolgte die Betätigung der Kupplungseinrichtung unter Einsatz einer zwischen den beiden Rotoren wirksamen Getriebeeinrichtung die an sich mehrere Umdrehungen, oder zumindest relativ große Drehwinkel der beiden Rotoren zueinander zulässt. Mit diesem Ansatz kann die Kupplungseinrichtung mit sehr hohen Stellkräften betätigt werden. Es sind auch Bauweisen möglich, bei welchen die Betätigung der Kupplungseinrichtung nur relativ geringe Differenzwinkel, z.B. von lediglich 45° erfordert. Insbesondere bei derartigen Bauformen kann es für die Betätigung der Kupplungseinrichtung ausreichen, dass an einem der beiden Rotoren ein Schubmoment anliegt das eben eine Betätigung der Kupplungseinrichtung bewirkt. Eine präzise Einstellung einer Drehwinkeldifferenz ist dann nicht erforderlich. Die zur Betätigung der Kupplungseinrichtung vorgesehene Stellmechanik kann ab einem vorgegebenen Differenzdrehwinkel in eine Anschlagstellung gelangen in welcher sich der Leistungsbeitrag beider Elektromotoren zum Antriebsmoment summiert, ohne dass hierbei eine übermäßige Stellkrafterhöhung erfolgt. Es ist auch möglich, in der Antriebseinrichtung schaltbar ansteuerbare, insbesondere elektromagnetisch ansteuerbare Rast- oder Sperrmittel vorzusehen die es ermöglichen, einen eingestellten Kupplungszustand auch unabhängig von den durch die Elektromotoren generierten Antriebs- oder Bremsmomente beizubehalten. In the embodiments described above, the actuation of the coupling device was carried out using an effective between the two rotors gear means per se several revolutions, or at least relatively large rotation angle of the two rotors to each other. With this approach, the coupling device can be operated with very high actuating forces. Structures are also possible in which the operation of the coupling device only involves relatively small differential angles, e.g. requires only 45 °. In particular, in such designs, it may be sufficient for the actuation of the coupling device that a thrust torque is applied to one of the two rotors which just causes an actuation of the coupling device. A precise adjustment of a rotational angle difference is then not required. The actuating mechanism provided for actuating the clutch device can reach a stop position starting from a predetermined differential rotational angle, in which the power contribution of both electric motors totals to the drive torque, without an excessive increase in the actuating force occurring in this case. It is also possible, in the drive device switchable controllable, in particular electromagnetically controllable locking or locking means provide which make it possible to maintain a set clutch state regardless of the generated by the electric motors drive or braking torques.
