Description

Die Erfindung betrifft einen Antriebsstrang für ein Hybrid-Kraftfahrzeug, das eine Brennkraftmaschine und einen Elektromaschine mit einem Stator und einem Rotor aufweist, wobei die Brennkraftmaschine oder der Rotor der Elektromaschine jeweils alleine oder beide zusammen mittels wenigstens einer Kupplung mit einer Getriebeeingangswelle verbindbar sind.The The invention relates to a drive train for a hybrid motor vehicle, an internal combustion engine and an electric machine with a Stator and a rotor, wherein the internal combustion engine or the rotor of the electric machine each alone or both together by means of at least one clutch with a transmission input shaft are connectable.

Ein derartiger Antriebsstrang ist in der DE 11 2005 001 586 A1 beschrieben. Der Antriebsstrang besteht aus einer mit dem Verbrennungsmotor verbundenen Antriebswelle, einer mit der Antriebswelle und einer Getriebeeingangswelle verbundenen Kupplung sowie mit einer weiteren, einen Rotor einer Elektromaschine mit der Getriebeeingangswelle kuppelbaren Kupplung. Konzentrisch zum Rotor ist ein gehäusefester Stator angeordnet, so dass wahlweise die Brennkraftmaschine oder die aus dem Stator und Rotor bestehende Elektromaschine oder beide zusammen mit der Getriebeeingangswelle verbindbar sind.Such a drive train is in the DE 11 2005 001 586 A1 described. The drive train consists of a drive shaft connected to the internal combustion engine, a coupling connected to the drive shaft and a transmission input shaft, and a further clutch which can be coupled to the rotor of an electric machine with the transmission input shaft. Concentric with the rotor, a stator fixed to the housing is arranged, so that either the internal combustion engine or the existing of the stator and rotor electric machine or both can be connected together with the transmission input shaft.

Bei einer solchen Anordnung mit einem permanent erregten Rotor wird es als nachteilig beurteilt, dass der Rotor der Elektromaschine auch dann angetrieben wird, wenn die Brennkraftmaschine mit der Getriebeeingangswelle gekuppelt ist und der Rotor sozusagen leer mitläuft. Bei dieser Betriebsweise wird die Elektromaschine also weder motorisch noch generatorisch betrieben. Dabei entstehen elektrische Verluste, die besonders hoch sind, wenn der Elektromaschine als permanentmagneterregter Synchronmotor ausgebildet ist, da in den Wicklungen der Elektromaschine hohe Spannungen induziert werden, die durch eine entgegengesetzt gerichtete Spannungsbeaufschlagung ausgeglichen werden müssen, um einen zu hohen, induzierten Spannungsanstieg zu vermeiden, der die Leistungselektronik der Elektromaschine beschädigen kann.at such an arrangement with a permanently excited rotor judged it to be disadvantageous that the rotor of the electric machine is also driven when the internal combustion engine with the transmission input shaft is coupled and the rotor runs along, so to speak, empty. at This mode of operation, the electric machine is thus neither motor still operated as a generator. This causes electrical losses, which are particularly high when the electric machine as a permanent magnet excited Synchronous motor is formed, as in the windings of the electric machine high voltages are induced by an opposite directional voltage must be balanced, to avoid too high an induced voltage rise, the damage the power electronics of the electric machine can.

Der Anteil dieser Verluste kann im höheren Drehzahlbereich auf bis zu 10% der Leistung der Elektromaschine ansteigen.Of the Share of these losses can be in the higher speed range increase up to 10% of the electric machine's output.

Dementsprechend liegt der Erfindung die Aufgabe zugrunde, die Leerlaufverluste einer solchen Elektromaschine in einem Hybrid-Antriebsstrang mit einfachen Mitteln weitestgehend zu beseitigen und die Beaufschlagung der Wicklungen der Elektromaschine mit einer Gegenspannung, die regeltechnisch aufwendig ist, zu vermeiden.Accordingly The invention is based on the object, the no-load losses of a such electric machine in a hybrid powertrain with simple Means to eliminate as much as possible and the loading of the windings the electric machine with a counter voltage, the technical control consuming is to avoid.

Gemäß den Merkmalen des Hauptanspruchs geht die Erfindung daher aus von einem Antriebsstrang für ein Hybrid-Kraftfahrzeug, der eine Brennkraftmaschine und eine Elektromaschine mit einem Stator und einem Rotor aufweist, wobei die Brennkraftmaschine oder der Rotor der Elektromaschine jeweils alleine oder beide zusammen mittels wenigstens einer Kupplung mit einer Getriebeeingangswelle verbindbar sind. Zur Lösung der gestellten Aufgabe ist bei diesem Hybrid-Antriebsstrang zudem vorgesehen, dass der Stator in einem Gehäuse drehbar gelagert und bei Bedarf, also bei elektromotorischem oder generatorischen Betrieb, mittels einer Kupplung mit dem Gehäuse drehfest verbindbar ist.According to the Features of the main claim, the invention is therefore based on a Powertrain for a hybrid motor vehicle, an internal combustion engine and an electric machine having a stator and a rotor, wherein the internal combustion engine or the rotor of the electric machine each alone or both together by means of at least one clutch can be connected to a transmission input shaft. To the solution the task is also in this hybrid powertrain provided that the stator rotatably mounted in a housing and if necessary, so in electromotive or generator Operation, rotatably by means of a coupling with the housing is connectable.

Im Leerlauf der Elektromaschine, wenn diese also weder motorisch noch generatorisch betrieben wird, wird die Kupplung zwischen dem Stator und dem Gehäuse gelöst, so dass sich der Stator frei drehen kann. Dadurch wird der Stator aufgrund elektromagnetischer Kräfte vom Rotor zu einer Drehung in der Statorlagerung veranlasst, so dass der Schlupf zwischen dem Stator und dem Rotor im Leerlauf sehr gering oder gleich Null ist und dementsprechend auch keine gefährliche Leerlaufspannung in den Wicklungen der Elektromaschine induziert wird.in the Idling of the electric machine, so if this neither motor nor is operated as a generator, the coupling between the stator and the housing is loosened, leaving the stator can rotate freely. As a result, the stator is due to electromagnetic Forces from the rotor to a rotation in the stator bearing causing the slip between the stator and the rotor idle is very low or zero and accordingly no dangerous open circuit voltage in the windings of the Electric machine is induced.

Es ist zwar nicht zwingend erforderlich, den Stator synchron mit dem Rotor mitdrehen zu lassen, jedoch ist es auf einfache Weise möglich, auch zwi schen dem Stator und dem Rotor eine Kupplung anzuordnen, die darin bestehen kann, dass der Wicklung des Stators der Elektromaschine Strom zugeführt wird, wobei diese Stromzufuhr, wenn die Elektromaschine als permanentmagneterregter Synchronmotor ausgebildet ist, durch Gleichstrom erfolgt. In diesem Fall entsteht zwischen dem Rotor und dem Stator noch ein nur durch die Lagerreibung bedingter, geringfügiger Schlupf, der sich jedoch vollständig beseitigen lässt, wenn zwischen dem Stator und dem Rotor eine mechanische Reibungskupplung angeordnet ist und diese geschlossen wird.It Although not mandatory, the stator in sync with the Turning the rotor, but it is easily possible also between the stator and the rotor to arrange a clutch, which may consist in that the winding of the stator of the electric machine Power is supplied, this power supply when the Electric machine designed as a permanent magnet synchronous motor is done by direct current. In this case arises between the rotor and the stator still only due to the bearing friction, Slight slippage, however, completely eliminate if between the stator and the rotor a mechanical friction clutch is arranged and this closed becomes.

Wenn der Stator der Elektromaschine Wicklungen aufweist, denen Strom zugeführt wird, wenn der Elektromaschine Leistung an die Abtriebswelle abgibt, oder wenn der Elektromaschine als Generator angetrieben wird und Leistung an eine Fahrzeugbatterie abgibt, ist eine elektrische Verbindung zwischen dem Gehäuse des Stators und dem Stator erforderlich, die vorteilhafterweise über Schleifringe erfolgt.If the stator of the electric machine has windings that power is supplied when the electric machine power to the Output shaft, or if the electric machine as a generator is powered and outputs power to a vehicle battery is an electrical connection between the housing of the stator and the stator required, which advantageously over Slip rings take place.

Die Kupplung zwischen dem Stator und dem Rotor der Elektromaschine kann aber auch mittels einer Reibkupplung erfolgen, die den drehbar gelagerten Stator mit der den Rotor tragenden Rotorwelle bedarfsweise verbindet.The Coupling between the stator and the rotor of the electric machine can but also by means of a friction clutch, which rotatably mounted Stator with the rotor shaft carrying the rotor, if necessary, connects.

Mehrere Ausführungsbeispiele und weitere Vorteile der Erfindung werden im Zusammenhang mit der beigefügten Zeichnung erläutert. In dieser zeigtSeveral Embodiments and other advantages of the invention will be explained in conjunction with the accompanying drawings. In this shows

3 eine schematische Darstellung des Antriebsstrangs mit nur einer Kupplung zwischen dem Rotor der Elektromaschine und der Getriebeeingangswelle. 3 a schematic representation of the drive train with only one clutch between the rotor of the electric machine and the transmission input shaft.

Eine nur schematisch dargestellte Brennkraftmaschine 1 ist über eine Antriebswelle 2 und eine Schaltkupplung 3 mit einer Getriebeeingangswelle 6 kuppelbar. Auf der Getriebeeingangswelle 6 ist drehfest ein Rotor 4 einer einen Stator 5 aufweisenden Elektromaschine befestigt. Der Stator 5 der Elektromaschine ist in einem Getriebegehäuse 7 drehbar gelagert, und die Stromzufuhr zu Wicklungen des Stators 5 erfolgt über Schleifringe 8, die mit Stromanschlüssen 9 am Gehäuse 7 zusammenwirken.An only schematically illustrated internal combustion engine 1 is via a drive shaft 2 and a clutch 3 with a transmission input shaft 6 coupled. On the transmission input shaft 6 is rotatably a rotor 4 one a stator 5 attached electric machine attached. The stator 5 the electric machine is in a gearbox 7 rotatably mounted, and the power supply to windings of the stator 5 via slip rings 8th with power connections 9 on the housing 7 interact.

Der Stator 5 ist mittels einer Schaltkupplung 10 mit dem Gehäuse 7 drehfest verbindbar. Soll die aus dem Rotor 4 und dem Stator 5 bestehende Elektromaschine die Getriebeeingangswelle 6 alleine antreiben, ist die Schaltkupplung 3 ausgerückt und die Gehäusekupplung 10 eingerückt, so dass der Stator 5 drehfest mit dem Gehäuse 7 verbunden ist und durch eine gesteuerte Stromversorgung der Wicklungen des Stators 5 eine Antriebskraft des Rotors 4 erzeugt wird. Durch Einrücken der Schaltkupplung 3 lässt sich die Leistung der Brennkraftmaschine 1 zusätzlich über die Antriebswelle 2 und die Getriebeeingangswelle 6 auf ein nicht dargestelltes Getriebe übertragen.The stator 5 is by means of a clutch 10 with the housing 7 rotatably connected. Let's get out of the rotor 4 and the stator 5 existing electric machine, the transmission input shaft 6 driving alone is the clutch 3 disengaged and the housing coupling 10 indented, leaving the stator 5 rotatably with the housing 7 is connected and by a controlled power supply to the windings of the stator 5 a driving force of the rotor 4 is produced. By engaging the clutch 3 can the performance of the internal combustion engine 1 additionally via the drive shaft 2 and the transmission input shaft 6 transferred to a not shown gear.

Wird nur die Leistung der Brennkraftmaschine 1 benötigt, bleibt die Schaltkupplung 3 eingerückt, die Gehäusekupplung 10 wird ausgerückt und die Stromzufuhr zum Stator 5 unterbrochen. Der Stator 5 kann sich dann frei mit dem Rotor 4 mitdrehen, so dass keine hohe, gefährliche Leerlaufspannung in den Wicklungen des Stators 5 induziert wird. Insbesondere, wenn die Elektromaschine als permanentmagneterregter Synchronmotor ausgebildet ist und die Permanentmagneten im Rotor 4 angeordnet sind, ist dieser Mitnahmeeffekt besonders ausgeprägt.Only the power of the internal combustion engine 1 needed, the clutch remains 3 engaged, the housing coupling 10 is disengaged and the power to the stator 5 interrupted. The stator 5 can then become free with the rotor 4 turn it around so that there is no high, dangerous no-load voltage in the windings of the stator 5 is induced. In particular, when the electric machine is designed as a permanent magnet synchronous motor and the permanent magnets in the rotor 4 are arranged, this entrainment effect is particularly pronounced.

Zusätzlich ist es auch möglich, zwischen dem Stator 5 und der Rotorwelle 13 eine weitere mechanische Reibungskupplung 11 anzuordnen, die im Leerlauf der Elektromaschine 4, 5 eine drehfeste Verbindung zwischen dem Rotor 4 und dem Stator 5 herstellt.In addition, it is also possible between the stator 5 and the rotor shaft 13 another mechanical friction clutch 11 to arrange the idling of the electric machine 4 . 5 a non-rotatable connection between the rotor 4 and the stator 5 manufactures.

Eine weitere Möglichkeit, den Stator 5 mit dem Rotor 4 zu koppeln besteht darin, den Stator 5 mit einer Gleichspannung über die Schleifringe 8 und die Stromanschlüsse 9 zu beaufschlagen, da dann der Rotor 4 und der Stator 5 wie eine elektromagnetische Kupplung mit sehr geringen Schlupf wirken.Another way, the stator 5 with the rotor 4 To couple is the stator 5 with a DC voltage across the slip rings 8th and the power connections 9 to act on, because then the rotor 4 and the stator 5 how an electromagnetic clutch with very little slippage act.

In 2 ist eine zusätzliche, ausgangsseitige Schaltkupplung 12 dargestellt, durch die der Rotor 4 mit der Getriebeeingangswelle 6 koppelbar oder entkoppelbar ist, während in 3 die eingangsseitige Schaltkupplung 3 entfallen ist, die ausgangsseitige Schaltkupplung 12 jedoch vorhanden ist.In 2 is an additional, output-side clutch 12 represented by the rotor 4 with the transmission input shaft 6 can be coupled or decoupled while in 3 the input-side clutch 3 has been omitted, the output-side clutch 12 however, it is present.

Allen drei Ausführungsbeispielen ist gemeinsam, dass der Stator 4 im Gehäuse 7 drehbar gelagert ist und sich mit dem Gehäuse 7 mittels einer Gehäusekupplung 10 dort ankuppeln lässt bzw. entkuppeln lässt. Zusätzlich kann eine Kupplung 11 zwischen dem Rotor 4 und dem Stator 5 vorgesehen sein, die als mechanische Reibungskupplung ausgebildet sein kann oder als Elektromagnetkupplung durch den Rotor 4 und den Stator 5 gebildet ist.All three embodiments have in common that the stator 4 in the case 7 is rotatably mounted and connected to the housing 7 by means of a housing coupling 10 can be coupled there or decoupled. In addition, a clutch 11 between the rotor 4 and the stator 5 be provided, which may be formed as a mechanical friction clutch or as an electromagnetic clutch by the rotor 4 and the stator 5 is formed.
