Description
Die vorliegende Erfindung betrifft einem Antriebsstrang für ein Kraftfahrzeug mit einem Verbrennungsmotor und mit einer elektrischen Maschine.The present invention relates to a drive train for a motor vehicle with an internal combustion engine and with an electric machine.

Der Erfindung liegt die Aufgabe zugrunde, einen einfach zu montierenden Antriebsstrang für ein Hybridfahrzeug darzustellen.The invention has for its object to present an easy-to-install drive train for a hybrid vehicle.
Diese Aufgabe wird gelöst durch einen Antriebsstrang gemäß Patentanspruch 1. Es wird somit ein Antriebsstrang vorgeschlagen welcher umfasst: einen Verbrennungsmotor mit einer Kurbelwelle, eine elektrische Maschine mit einem Rotor und einem Stator sowie eine axial zwischen dem Verbrennungsmotor und der elektrischen Maschine angeordnete Kupplung mittels der die elektrische Maschine mit der Kurbelwelle des Verbrennungsmotors in Wirkverbindung steht oder bringbar ist und ein abtriebsseitig von der elektrischen Maschine angeordnetes Anfahrelement.This object is achieved by a drive train according to claim 1. It is thus proposed a drive train comprising: an internal combustion engine with a crankshaft, an electric machine with a rotor and a stator and an axially disposed between the engine and the electric motor coupling means of the electric machine is in operative connection with the crankshaft of the internal combustion engine or can be brought and a driven element arranged on the output side of the electric machine.
Es ist dabei vorgesehen, dass die Kupplung eine Kupplungsscheibe aufweist, die mit einer in der Kurbelwelle oder dem Schwungrad gelagerten Zwischenwelle drehfest verbunden ist.It is provided that the clutch has a clutch disc which is rotatably connected to a mounted in the crankshaft or the flywheel intermediate shaft.
Die Kupplungsscheibe kann als dünnes Federblech oder dergleichen ausgebildet sein. Die Verbindung mit der Zwischenwelle kann beispielsweise über eine mit Längsverzahnungen versehene Wellen-Nabenverbindung realisiert werden. Das bedeutet, daß die Kupplungsscheibe ganz einfach auf die Zwischenwelle aufgeschoben werden kann und dort dennoch sicher und vor allem drehfest gehalten wird. Eine solche Verbindung ist in anderem Zusammenhang beispielsweise in der
Die in dem Antriebsstrang vorhandene elektrische Maschine kann in Außenläufer- oder Innenläuferbauweise ausgebildet sein. Als elektrische Maschinen sind beispielsweise Synchronmaschinen, und hier insbesondere permanenterregte Synchronmaschinen, zu nennen. Dabei ist die Erfindung nicht auf bestimmte Verwendungsbereiche beschränkt. Eine besonders erwähnenswerte Maschine, an der die Erfindung nachfolgend erläutert wird, ohne den Schutzbereich jedoch auf dieses konkrete Beispiel zu beschränken, ist der Starter-Generator für Fahrzeuge. Hierbei handelt es sich um eine elektrische Maschine, deren Rotor über die Kurbelwellenlagerung des Verbrennungsmotors gelagert ist. Der Starter-Generator wird nicht nur zum Starten und Stoppen des Verbrennungsmotors verwendet, sondern er kann auch während des Motorbetriebs verschiedene Funktionen übernehmen, wie beispielsweise Bremsfunktionen, Boosterfunktionen, Batteriemanagement, aktive Schwingungsdämpfung, Synchronisierung des Verbrennungsmotors oder dergleichen.The existing in the drive train electric machine may be formed in external rotor or internal rotor design. As electrical machines are, for example, synchronous machines, and in particular permanently excited synchronous machines to call. The invention is not limited to specific fields of use. A particularly noteworthy machine, on which the invention is explained below, but without limiting the scope of protection to this specific example, is the starter-generator for vehicles. This is an electric machine whose rotor is mounted on the crankshaft bearing of the internal combustion engine. The starter generator is not only used to start and stop the engine, but it can also take on various functions during engine operation, such as Brake functions, booster functions, battery management, active vibration damping, synchronization of the internal combustion engine or the like.
Vorteilhafte Ausgestaltungen des erfindungsgemäßen Antriebsstrangs ergeben sich aus den Unteransprüchen.Advantageous embodiments of the drive train according to the invention will become apparent from the dependent claims.
Gemäß einer Ausgestaltung kann die Kupplung ein Schwungrad aufweisen, das mit der Kurbelwelle drehfest verbunden ist. Das Schwungrad kann vorteilhaft als Blechelement ausgebildet sein. Eine solche Ausgestaltung des Schwungrads ist insbesondere dann sinnvoll, wenn die Brennkraftmaschine bereits von sich aus rund läuft und eine große Masse des Schwungrads nicht zwingend erforderlich ist. In weiterer Ausgestaltung kann die Kupplung unlösbar mit der Kurbelwelle verbunden sein.According to one embodiment, the clutch may comprise a flywheel, which is rotatably connected to the crankshaft. The flywheel can be advantageously designed as a sheet metal element. Such an embodiment of the flywheel is particularly useful when the internal combustion engine is already running on its own and a large mass of the flywheel is not absolutely necessary. In a further embodiment, the clutch can be permanently connected to the crankshaft.
Im radial äußeren Bereich der Kupplung kann weiterhin ein geeignetes Element zur Torsionsdämpfung vorgesehen sein. Dadurch werden Drehschwingungen zwischen der Brennkraftmaschine und der mit dem Torsionsschwingungsdämpfer bestückten Kupplung gedämpft. Derartige Torsionsschwingungsdämpfer sind grundsätzlich aus dem Stand der Technik bekannt. Sie können beispielsweise aus einer Federeinrichtung und einer Reibeinrichtung bestehen. Die Federeinrichtung kann sich unter Lasteinwirkung begrenzt verdrehen, während die Reibeinrichtung die bei Verdrehung auftretenden Drehschwingungen durch Reibung dämpft.In the radially outer region of the coupling may further be provided a suitable element for torsional damping. As a result, torsional vibrations are damped between the engine and equipped with the torsional vibration damper clutch. Such torsional vibration dampers are basically known from the prior art. You can for example consist of a spring device and a friction device. The spring device can rotate limited under load, while the friction device dampens the torsional vibrations occurring during rotation by friction.
Durch die besondere Anordnung des Torsionsschwingungsdämpfers ist es nicht mehr erforderlich, daß die beiden Komponenten axial hintereinander angeordnet werden müssen, wodurch der benötigte axiale Bauraum reduziert wird. Durch die Verwendung eines solchen Torsionsschwingungsdämpfers wird es weiterhin erreicht, daß die Anzahl der benötigten Bauteile reduziert wird. So können einzelne Bauteile, die sowohl für den Torsionsschwingungsdämpfer, als auch für die Kupplung benötigt werden, nur einmal – anstatt wie bisher zweimal – vorhanden sein, was sowohl die Herstellungskosten, als auch den erforderlichen axialen Bauraum reduziert.Due to the special arrangement of the torsional vibration damper, it is no longer necessary that the two components must be arranged axially one behind the other, whereby the required axial space is reduced. By using such a torsional vibration damper, it is further achieved that the number of required components is reduced. Thus, individual components that are required for both the torsional vibration damper, as well as for the clutch, only once - instead of twice as before - be present, which reduces both the manufacturing cost, as well as the required axial space.
Vorteilhaft kann zumindest ein Teil des Schwungrads von der Kupplung gleichzeitig auch als Primärblech des Torsionsschwingungsdämpfers ausgebildet sein. Dadurch kann die Anzahl der benötigten Bauteile reduziert werden, was zu den oben geschilderten Vorteilen führt.Advantageously, at least a portion of the flywheel of the clutch can be formed simultaneously as a primary plate of the torsional vibration damper. As a result, the number of required components can be reduced, which leads to the advantages described above.
Vorzugsweise kann der Torsionsschwingungsdämpfer eine oder mehrere Dämpfungsfedern aufweisen, die am radialen äußeren Ende der Kupplung angeordnet ist/sind, insbesondere am radialen äußeren Ende des als Primärblech fungierenden Schwungrads oder Schwungradteils der Kupplung. Durch die Dämpfungsfeder(n) können die auf das Primärblech wirkenden Torsionsschwingungen gedämpft werden.Preferably, the torsional vibration damper may comprise one or more damping springs disposed at the radially outer end of the coupling, in particular at the radial outer end of the flywheel or flywheel part of the coupling functioning as a primary plate. By the damping spring (s) acting on the primary sheet torsional vibrations can be damped.
Der Torsionsschwingungsdämpfer kann weiterhin ein Mitnehmerblech aufweisen, das mit dem Primärblech verbunden ist. Dieses Mitnehmerblech kann ebenfalls ein Teilbereich des Schwungrads der Kupplung sein, so daß ein sogenanntes geteiltes Schwungrad vorliegt, das aus dem Primärblech und dem Mitnehmerblech gebildet ist.The torsional vibration damper may further comprise a driver plate which is connected to the primary plate. This driver plate may also be a portion of the flywheel of the clutch, so that there is a so-called split flywheel, which is formed from the primary plate and the driving plate.
Bei einer solchen Ausgestaltung kann das von der Kurbelwelle übertragene Drehmoment zunächst auf den als Primärblech ausgebildeten Teilbereich des Schwungrads von der Kupplung und von dort über die Dämpfungsfedern auf das Mitnehmerblech sowie von dort schließlich auf die Kupplungsscheibe übertragen werden. Die Kupplungsbeläge werden vorzugsweise aufgeklebt, so daß keine gesonderte Belagfeder nötig ist.In such an embodiment, the torque transmitted by the crankshaft can first be transmitted to the part of the flywheel formed as a primary plate from the clutch and from there via the damping springs to the driver plate and from there finally to the clutch disc. The clutch linings are preferably glued, so that no separate pad spring is needed.
Vorteilhaft kann der Durchmesser der Kupplung, insbesondere des Schwungrades und/oder der Kupplungsscheibe kleiner sein als der radiale Abstand von der Drehachse des Rotors zum Luftspalt. Insbesondere kann der Durchmesser kleiner sein als der radiale Abstand von der Drehachse des Rotors zum Stator. Damit liegen die genannten Bauelemente vorteilhaft radial innerhalb des Luftspalts oder gar des Stators. Der Statorträger und damit auch die elektrische Maschine ist somit größer als die Kupplung beziehungsweise deren Elemente, so daß der bisher erforderliche Bauraum zwischen den einzelnen Bauelementen reduziert werden kann, was zu einer vorteilhaften Verkürzung der axialen Baulänge führt. Je nach konstruktiver Ausgestaltung des als Blechträger ausgebildeten Statorträgers ist es sogar möglich, daß sich die Kupplung oder Einzelelemente davon auf der gleichen axialen Höhe wie der Statorträger befinden, was bedeutet, daß diese Elemente koaxial zueinander angeordnet sind. Dadurch kann der axiale Bauraum noch weiter verkürzt werden.Advantageously, the diameter of the coupling, in particular of the flywheel and / or the clutch disc may be smaller than the radial distance from the axis of rotation of the rotor to the air gap. In particular, the diameter may be smaller than the radial distance from the axis of rotation of the rotor to the stator. Thus, the said components are advantageously radially within the air gap or even the stator. The stator and thus the electric machine is thus greater than the clutch or its elements, so that the previously required space between the individual components can be reduced, resulting in an advantageous shortening of the axial length. Depending on the structural design of the stator carrier designed as a sheet metal carrier, it is even possible for the coupling or individual elements thereof to be at the same axial height as the stator carrier, which means that these elements are arranged coaxially with one another. As a result, the axial space can be shortened even further.
Mit Vorteil arbeitet die Kupplung ausschließlich als Schwungstartkupplung zum Starten des Verbrennungsmotors. Wenn die Brennkraftmaschine gestartet werden soll, wird zunächst die elektrische Maschine hochgefahren, bis der Rotor die erforderliche Drehzahl erreicht hat. Ist dies der Fall, schließt die Kupplung schlagartig, so daß die Kurbelwelle, beispielsweise über ein mit dieser verbundenes Kupplungs-Schwungrad, mitgerissen wird, so daß das für den Start der Brennkraftmaschine erforderliche Drehmoment übertragen wird. Wenn die Brennkraftmaschine im Normalbetrieb läuft, kann die Kupplung geschlossen bleiben, so daß das über die Kurbelwelle übertragene Drehmoment der Brennkraftmaschine auf die elektrische Maschine und von dort, falls gewünscht, auch auf andere Bauelemente des Antriebsstrangs übertragen werden kann (Drehmomentmitnahme).Advantageously, the clutch operates exclusively as a fly-starting clutch for starting the internal combustion engine. When the engine is to be started, first the electric machine is started up until the rotor has reached the required speed. If this is the case, the clutch closes abruptly, so that the crankshaft, for example via a clutch flywheel connected thereto, entrained, so that the torque required for the start of the internal combustion engine is transmitted. When the internal combustion engine is running in normal operation, the clutch can remain closed, so that the torque transmitted via the crankshaft of the internal combustion engine to the electric machine and from there, if desired, to other components of the Drivetrain can be transmitted (torque take).
Vorzugsweise kann die Kupplung ein als Ausrücken ausgebildetes Betätigungselement aufweisen, wobei das Betätigungselement vorteilhaft am Statorträger ausgebildet ist. Bei entsprechender Ausgestaltung des Statorträgers kann erreicht werden, daß sich das Betätigungselement dann koaxial zum Statorträger selbst befindet, das zu einer vorteilhaften Verkürzung des erforderlichen axialen Bauraums führt.Preferably, the coupling may have a trained as disengaging actuator, wherein the actuating element is advantageously formed on the stator. With appropriate design of the stator can be achieved that the actuator is then coaxial with the stator itself, which leads to an advantageous shortening of the required axial space.
Die Realisierung einer wie vorstehend beschriebenen Kupplung soll anhand eines Beispiels exemplarisch verdeutlicht werden. An der Kurbelwelle der Brennkraftmaschine wird das Schwungrad mit der dazugehörigen Kupplungsscheibe und einer Kupplungsdruckplatte angeflanscht. Im Anschluß daran befindet sich das als Betätigungselement ausgebildete Ausrücksystem für die Kupplung, das am Statorträger angeordnet ist. Die Übertragung des Drehmoments erfolgt über die gelagerte Zwischenwelle, die das Moment von der Kupplungsscheibe auf den Rotorträger der elektrischen Maschine und möglicherweise parallel auf weitere nachfolgende Bauelemente im Antriebsstrang überträgt.The realization of a coupling as described above will be illustrated by way of example by way of example. At the crankshaft of the internal combustion engine, the flywheel with the associated clutch disc and a clutch pressure plate is flanged. Subsequently, there is designed as an actuating element release system for the clutch, which is arranged on the stator. The transmission of the torque takes place via the mounted intermediate shaft which transmits the torque from the clutch disc to the rotor carrier of the electric machine and possibly in parallel to further downstream components in the drive train.
Vorteilhaft kann der Rotor über einen Rotorträger mit der Zwischenwelle drehfest verbunden sein. Diese Zwischenwelle überträgt ein von einer Brennkraftmaschine mit Hilfe einer Kurbelwelle erzeugtes Drehmoment von dieser Kurbelwelle auf den Rotorträger und damit auf den Rotor der elektrischen Maschine, oder umgekehrt. Wenn die elektrische Maschine beispielsweise als Starter für eine Brennkraftmaschine eingesetzt wird, wird das von dem Rotor erzeugte Drehmoment über die Zwischenwelle auf die Kurbelwelle der Brennkraftmaschine übertragen. Im Normalbetrieb der Brennkraftmaschine kann das von dieser erzeugte Drehmoment dann über die Zwischenwelle auf den Rotor und weiter parallel auf möglicherweise nachfolgende, in bezug auf die elektrische Maschine abtriebsseitig im Antriebsstrang angeordnete Bauteile übertragen werden. Schließlich kann die Zwischenwelle auch als Lagersitz für nachfolgende Bauelemente dienen.Advantageously, the rotor can be rotatably connected via a rotor carrier with the intermediate shaft. This intermediate shaft transmits a torque generated by an internal combustion engine by means of a crankshaft from this crankshaft to the rotor carrier and thus to the rotor of the electric machine, or vice versa. When the electric machine is used, for example, as a starter for an internal combustion engine, the torque generated by the rotor is transmitted via the intermediate shaft to the crankshaft of the internal combustion engine. In normal operation of the internal combustion engine, the torque generated by this can then be transmitted via the intermediate shaft to the rotor and further in parallel to possibly subsequent, arranged with respect to the electrical machine on the drive side in the drive train components. Finally, the intermediate shaft can also serve as a bearing seat for subsequent components.
Vorzugsweise kann die Zwischenwelle im Statorträger gelagert sein, wozu der Statorträger ein Lager aufweisen kann. Je nach geometrischer Ausgestaltung des Statorträgers kann sich die Zwischenwelle auf gleicher axialer Höhe, das heißt koaxial zum Statorträger befinden, wodurch der erforderliche axiale Bauraum reduziert wird. Durch das Lager, das sich vorteilhaft zwischen dem Statorträger, der Zwischenwelle und dem Rotorträger befindet, kann auch die Größe des Luftspalts zwischen dem Rotor und dem Stator konstruktiv bestimmt, das heißt eingestellt werden. Weiterhin wird durch diese Art einer festen Verbindung sichergestellt, daß der Luftspalt zu jedem Zeitpunkt des Betriebs immer konstant, das heißt gleich groß bleibt. Eine bisher notwendige aufwendige Justierung oder Nachjustierung zur Einstellung des Luftspalts kann nunmehr entfallen.Preferably, the intermediate shaft may be mounted in the stator, for which purpose the stator can have a bearing. Depending on the geometric configuration of the stator carrier, the intermediate shaft may be located at the same axial height, that is to say coaxially to the stator carrier, whereby the required axial space is reduced. Due to the bearing, which is advantageously located between the stator, the intermediate shaft and the rotor arm, and the size of the air gap between the rotor and the stator can be determined constructively, that is set. Furthermore, it is ensured by this kind of a fixed connection that the air gap always constant at each time of operation, that is remains the same size. A hitherto necessary complex adjustment or readjustment for adjusting the air gap can now be omitted.
Die wie vorstehend beschriebene elektrische Maschine stellt eine in sich geschlossene Baueinheit des Antriebsstrangs dar, was von besonderem Vorteil ist. Im Gegensatz dazu wurden bisher häufig Schraubverbindungen am Rotor verwendet, insbesondere zur Einstellung des Luftspalts, so daß ein mögliches Spiel in den Schraubverbindungen bei der Montage als mögliche Fehlerquelle bei der Bestimmung des Luftspalts auftrat.The electric machine as described above represents a self-contained unit of the drive train, which is of particular advantage. In contrast, screw connections have been frequently used on the rotor, in particular for adjusting the air gap, so that a possible play in the screw connections during assembly as a possible source of error in the determination of the air gap occurred.
In weiterer Ausgestaltung kann der Rotorträger an seinem in bezug auf die Drehachse des Rotors radialen Ende eine Einrichtung zur Winkellagebestimmung aufweisen oder als Einrichtung zur Winkellagebestimmung ausgebildet sein. Eine solche Einrichtung ist erforderlich, da die genaue Rotorlage, insbesondere die Lage der Rotorpolpaare, während des Betriebs der elektrischen Maschine genau bekannt sein muß. Die Bestimmung der Winkellage kann auf verschiedene Weise erfolgen.In a further embodiment, the rotor carrier can have at its radial end with respect to the axis of rotation of the rotor a device for angular position determination or be designed as a device for angular position determination. Such a device is necessary because the exact rotor position, in particular the position of Rotorpolpaare must be known exactly during the operation of the electric machine. The determination of the angular position can be done in various ways.
Wenn eine Einrichtung zur Winkellagebestimmung am Rotorträger angeordnet ist, kann diese beispielsweise als Inkrementalgeberring, Resolver oder dergleichen ausgebildet sind. Derartige Einrichtungen sind aus dem Stand der Technik grundsätzlich bekannt. In anderer Ausgestaltung ist es denkbar, daß der Rotorträger selbst als Einrichtung zur Winkellagebestimmung ausgebildet ist. In diesem Fall könnte beispielsweise das in bezug auf die Drehachse des Rotors radiale freie Ende des Rotorträgers als Inkrementalgeberring oder dergleichen ausgebildet sein.If a device for angular position determination is arranged on the rotor carrier, this can be designed, for example, as an incremental encoder ring, resolver or the like. Such devices are basically known from the prior art. In another embodiment, it is conceivable that the rotor carrier itself is designed as a device for angular position determination. In this case, for example, could be formed as an incremental encoder ring or the like with respect to the axis of rotation of the rotor radial free end of the rotor carrier.
Gemäß der vorgeschlagenen Lösung ist im Antriebsstrang abtriebsseitig von der elektrischen Maschine als weiteres Bauelement ein Anfahrelement vorgesehen. Somit ist die elektrische Maschine im Antriebsstrang beispielsweise axial zwischen der Kupplung und dem Anfahrelement integriert. Das Anfahrelement kann beispielsweise – jedoch nicht ausschließlich – als ein Lastschaltgetriebe, ein Drehmomentwandler, etwa ein hydrodynamischer Wandler mit automatischem Getriebe, als ein Stufengetriebe, etwa ein CVT-Getriebe (continuous variable transmission), als eine Kupplung oder dergleichen ausgebildet sein.According to the proposed solution, a starting element is provided in the drive train on the output side of the electric machine as a further component. Thus, the electric machine in the drive train, for example, is integrated axially between the clutch and the starting element. The starting element may be, for example, but not limited to, a power shift transmission, a torque converter, such as a hydrodynamic converter with an automatic transmission, a step transmission, such as a CVT (Continuous Variable Transmission), a clutch, or the like.
Vorzugsweise kann das weitere als Anfahrelement ausgebildete Bauelement lösbar mit dem Rotorträger verbunden sein.Preferably, the further designed as a starting element can be releasably connected to the rotor carrier.
Vorteilhaft kann das Anfahrelement einen Durchmesser aufweisen, der kleiner ist als der radiale Abstand von der Drehachse des Rotors zum Luftspalt. Ähnlich wie bei der oben beschriebenen Kupplung kann durch eine solche Ausgestaltung der erforderliche axiale Bauraum verkürzt werden.Advantageously, the starting element may have a diameter which is smaller than the radial distance from the axis of rotation of the rotor to Air gap. Similar to the coupling described above, such an embodiment can reduce the required axial space.
Um auftretende Schwingungen dämpfen zu können, kann zwischen der elektrischen Maschine und dem weiteren Bauelement im Antriebsstrang, beispielsweise dem Anfahrelement, ein Schwingungsdämpfer, beispielsweise ein Torsionsschwingungsdämpfer, vorgesehen sein. Im Falle eines Torsionsschwingungsdämpfers kann dieser beispielsweise als Federkonstruktion, Zwei-Massen-Schwungrad oder dergleichen ausgebildet sein. Bei Ausgestaltung als Federkonstruktion kann der Torsionsschwingungsdämpfer primärseitig am Rotorträger und sekundärseitig am weiteren Bauelement, etwa dem Anfahrelement, angeordnet sein. Der Schwingungsdämpfer kann in bezug auf die Drehachse des Rotors radial innerhalb des Abstands Drehachse des Rotors-Luftspalt, koaxial zum Luftspalt oder im Bereich neben dem Luftspalt, das heißt axial benachbart zum Luftspalt, im Antriebsstrang angeordnet sein.In order to be able to damp vibrations that occur, a vibration damper, for example a torsional vibration damper, can be provided between the electric machine and the further component in the drive train, for example the starting element. In the case of a torsional vibration damper, this may for example be designed as a spring construction, two-mass flywheel or the like. In the embodiment as a spring construction, the torsional vibration damper can be arranged on the primary side on the rotor carrier and on the secondary side on the further component, for example the starting element. The vibration damper may be disposed radially inwardly of the axis of rotation of the rotor air gap, coaxial with the air gap or in the region adjacent the air gap, ie axially adjacent the air gap, in the drive train with respect to the axis of rotation of the rotor.
Vorzugsweise kann die Drehmomentmitnahme zwischen Rotor und dem weiteren Bauelement von der Drehachse des Rotors aus gesehen radial innen von der Zwischenwelle erfolgen. Damit fungiert die Zwischenwelle als Lagersitz für das weitere Bauelement.Preferably, the torque entrainment between the rotor and the further component seen from the axis of rotation of the rotor can be done radially inwardly of the intermediate shaft. Thus, the intermediate shaft acts as a bearing seat for the other component.
Um eine einfache Montage des Statorträgers zu gewährleisten, kann dieser vorteilhaft an einem Gehäuse angeordnet sein, das eines oder mehrere Elemente des Antriebsstrangs umgibt. In diesem Fall kann der Statorträger über eine Schraubverbindung oder dergleichen am Gehäuse befestigt sein. Es ist aber auch denkbar, daß der Statorträger zwischen zwei unterschiedlichen Gehäusen, beispielsweise mittels einer Einklemmverbindung oder dergleichen, angeordnet ist.In order to ensure a simple mounting of the stator carrier, this can be advantageously arranged on a housing which surrounds one or more elements of the drive train. In this case, the stator can be fixed via a screw or the like on the housing. But it is also conceivable that the stator is arranged between two different housings, for example by means of a Einklemmverbindung or the like.
Vorzugsweise kann von der Drehachse des Rotors aus gesehen der Luftspalt einen derart großen Abstand zur Drehachse aufweisen, daß zur elektrischen Maschine im Antriebsstrang benachbart angeordnete Bauelemente in bezug auf die Drehachse des Rotors eine radiale Ausdehnung aufweisen, die kleiner als der radiale Abstand von der Drehachse zum Luftspalt ist. Das bedeutet, daß die zur elektrischen Maschine benachbarten Bauelemente in bezug auf die Drehachse des Rotors einen Durchmesser in radialer Richtung aufweisen, der kleiner ist als der radiale Durchmesser der elektrischen Maschine. Die elektrische Maschine ist damit größer als die benachbarten Elemente, so daß sich diese – bei entsprechender Ausgestaltung des Statorträgers und/oder des Rotorträgers – radial innerhalb der elektrischen Maschine befinden. Dadurch wird eine Reduzierung des erforderlichen axialen Bauraums erreicht. Je nach Ausgestaltung des als Blechträger ausgebildeten Statorträgers und/oder Rotorträgers können einzelne Elemente und/oder Bestandteile der zur elektrischen Maschine benachbarten Elemente eines Antriebsstrangs nicht nur radial kleiner sein, sondern auch axial auf gleicher Höhe, das heißt koaxial zum Statorträger und/oder dem Rotorträger angeordnet sein. Dadurch kann eine noch platzsparendere Bauweise erreicht werden.Preferably, viewed from the axis of rotation of the rotor, the air gap have such a large distance from the axis of rotation that adjacent to the electrical machine in the drive train arranged components with respect to the axis of rotation of the rotor have a radial extent smaller than the radial distance from the axis of rotation Air gap is. This means that the adjacent to the electrical machine components with respect to the axis of rotation of the rotor have a diameter in the radial direction which is smaller than the radial diameter of the electric machine. The electric machine is thus larger than the adjacent elements, so that they - are radially inside the electric machine - with a corresponding design of the stator and / or the rotor carrier. As a result, a reduction of the required axial space is achieved. Depending on the configuration of the stator carrier and / or rotor carrier designed as a sheet metal carrier, individual elements and / or components of the elements of a drive train adjacent to the electrical machine can be not only radially smaller, but also axially at the same height, ie coaxial to the stator carrier and / or the rotor carrier be arranged. This allows an even more space-saving design can be achieved.
