Ein Fahrzeug mit den wesentlichen Merkmalen des Oberbegriffs des Patentanspruches 1 ist aus der DE 199 31 963 A1 bekannt. Weitere für Hybridfahrzeuge geeignete Antriebsstranganordnungen sind aus der DE 43 23 601 A1 , DE 196 31 384 C1 , WO 95/01884 und US 6,281,646 B1 bekannt.A vehicle having the essential features of the preamble of claim 1 is known from DE 199 31 963 A1 known. Other powertrain arrangements suitable for hybrid vehicles are known from DE 43 23 601 A1 . DE 196 31 384 C1 . WO 95/01884 and US 6,281,646 B1 known.

Neben dem aus der eingangs erwähnten DE 199 31 963 A1 bekannten Prinzip, bei dem eine als Kurbelwellen-Starter-Generator fungierende Elektromaschine auf der dem Getriebe gegenüberliegenden Seite des Verbrennungsmotors angeordnet ist, ist aus einer Vielzahl anderer Druckschriften bekannt, eine als Kurbelwellen-Starter-Generator fungierende Elektromaschine zwischen dem Verbrennungsmotor und dem Wandler eines Automatikgetriebes anzuordnen. Eine Anordnung der Elektromaschine im Bereich zwischen dem Verbrennungsmotor und dem Getriebe ist aus Bauraumgründen schwierig. Bekannt ist auch, einen Torsionsdämpfer in den Antriebsstrang zu integrieren, der zur Reduzierung von Torsinns-schwingungen der Kurbelwelle vorgesehen ist.In addition to the above-mentioned DE 199 31 963 A1 Known principle in which a functioning as a crankshaft starter alternator electric machine is disposed on the opposite side of the transmission of the engine is known from a variety of other publications, acting as a crankshaft starter generator electric machine between the engine and the converter of an automatic transmission to arrange. An arrangement of the electric machine in the area between the engine and the transmission is difficult for space reasons. It is also known to integrate a torsional damper in the drive train, which is provided for the reduction of Torsinns vibrations of the crankshaft.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. Advantageous embodiments and further developments of the invention are to refer to the dependent claims.

Ausgangspunkt der Erfindung ist ein Hybridfahrzeug, d. h. ein Fahrzeug, in dessen Antriebsstrang eine elektrische Maschine und ein Verbrennungsmotor vorgesehen ist. Das Fahrzeug weist ein Getriebe auf, das auf einer Abtriebsseite des Verbrennungsmotors angeordnet ist und das von einer Kurbelwelle des Verbrennungsmotors angetrieben wird. Die elektrische Maschine weist einen Stator und einen Rotor auf und ist dazu vorgesehen, in einem Motorbetriebszustand mechanische Leistung auf die Kurbelwelle des Verbrennungsmotors zu übertragen und in einem Generator-Betriebszustand von der Kurbelwelle gelieferte mechanische Leistung in elektrische Leistung umzuwandeln. Im Motorbetriebszustand kann der Verbrennungsmotor abgeschaltet oder eingeschaltet sein. Es kann also rein verbrennungsmotorisch, rein elektrisch oder elektrisch und gleichzeitig verbrennungsmotorisch gefahren werden. Für eine kostengünstige Integration der elektrischen Maschine in den Antriebsstrang ist vorgesehen, dass die elektrische Maschine auf der dem Getriebe gegenüberliegenden Seite des Verbrennungsmotors angeordnet ist.starting point The invention is a hybrid vehicle, i. H. a vehicle in whose Powertrain an electric machine and an internal combustion engine is provided. The vehicle has a gearbox on a Output side of the internal combustion engine is arranged and that of a crankshaft of the internal combustion engine is driven. The electric Machine has a stator and a rotor and is intended to in an engine operating condition, mechanical power to the crankshaft of the internal combustion engine and in a generator operating state from the crankshaft delivered mechanical power in electrical To transform performance. In the engine operating state, the internal combustion engine switched off or switched on. So it can be pure combustion engine, purely electric or electric and at the same time internal combustion engine be driven. For a cost-effective integration the electric machine in the drive train is provided that the electric machine is opposite to the gearbox Side of the internal combustion engine is arranged.

Der Kern der Erfindung besteht in der Kombination der Anordnung der elektrischen Maschine auf der dem Getriebe gegenüberliegenden Seite des Verbrennungsmotors und in einer Torsionsdämpfungseinrichtung, über die der Rotor der elektrischen Maschine mit der Kurbelwelle des Verbrennungs motors verbunden ist. Die Torsionsdämpfungseinrichtung ist dazu vorgesehen, die bei bestimmten Antriebsdrehzahlen im Antriebsstrang auftretenden Torsionsresonanzen, insbesondere der Kurbelwelle, zu dämpfen. Vorzugsweise ist die Torsionsdämpfungseinrichtung in einem Bereich angeordnet, der innerhalb des von dem Elektromotor eingenommenen Bauraums liegt.Of the Essence of the invention consists in the combination of the arrangement of electrical machine on the opposite side of the gearbox Side of the internal combustion engine and in a Torsionsdämpfungseinrichtung, about the rotor of the electric machine with the crankshaft of the Combustion engines is connected. The torsion damping device is intended to be used at certain input speeds in the powertrain occurring torsional resonances, in particular the crankshaft to attenuate. Preferably, the torsional damping device is in one Area disposed within the space occupied by the electric motor space lies.

Diese Anordnung bedingt, dass im rein elektromotorischen Betrieb der Verbrennungsmotor von der elektrischen Maschine mitgeschleppt wird. Im Vergleich zu Anordnungen, bei denen der Elektromotor zwischen dem Verbrennungsmotor und dem Getriebe angeordnet ist, treten bei der erfindungsgemäßen Anordnung keine oder zumindest wesentlich geringere Bauraumprobleme auf.These Arrangement requires that in purely electric motor operation of the internal combustion engine is dragged by the electric machine. Compared to Arrangements in which the electric motor between the internal combustion engine and the transmission is arranged, occur in the inventive Arrangement no or at least significantly less space problems on.

Nach einer Weiterbildung der Erfindung handelt es sich bei der elektrischen Maschine um eine Innenläufermaschine, d. h. um eine Maschine, bei der der Rotor radial innerhalb des Stators angeordnet ist. Vorzugsweise ist der Torsionsdämpfer radial innerhalb des Rotors angeordnet, was eine konstruktiv einfache Kopplung des Rotors über die Torsionsdämpfungs-einrichtung mit der Kurbelwelle des Verbrennungsmotors ermöglicht.To a development of the invention is in the electrical Machine around an internal rotor machine, d. H. to a machine, in which the rotor is arranged radially inside the stator. Preferably the torsion damper is arranged radially inside the rotor, what a structurally simple coupling of the rotor over the torsion damping device with the crankshaft of the Internal combustion engine allows.

Es liegt auf der Hand, dass die elektrische Maschine auch zum Starten des Verbrennungsmotors genutzt werden kann. Komponenten der Torsionsdämpfungseinrichtung können durch Komponenten des Elektromotors gebildet sein. Bei der oben beschriebenen Anordnung, bei der die Torsionsdämpfungseinrichtung radial innerhalb des Rotors angeordnet ist, bildet der Rotor die "Eingangsseite" der Torsionsdämpfungseinrichtung.It is obvious that the electric machine also to start of the internal combustion engine can be used. Components of the torsional damping device may be formed by components of the electric motor. In the arrangement described above, wherein the torsion damping device is arranged radially inside the rotor, the rotor forms the "Input side" of the torsion damping device.

Nach einer Weiterbildung der Erfindung ist die Torsionsdämpfungseinrichtung so ausgelegt, dass die Dämpfungscharakteristik der Torsionsdämpfungseinrichtung eine Funktion der Drehzahl des Rotors bzw. der Kurbelwelle ist.To a development of the invention is the torsional damping device designed so that the damping characteristic of the torsional damping device is a function of the speed of the rotor or the crankshaft.

Bei der Torsionsdämpfungseinrichtung kann es sich beispielsweise um eine Reibungstorsionsdämpfungseinrichtung, eine hydrodynamische Dämpfungseinrichtung oder um eine durch ein oder mehrere Elastomere gebildete Dämpfungseinrichtung handeln. Eine zusätzliche Torsionsschwingungsdämpfung kann im Generatorbetrieb der elektrischen Maschine durch eine aktive Ansteuerung der elektrischen Maschine erreicht werden. Der mechanischen Dämpfung kann also eine über den durch die elektrische Maschine fließenden Strom gesteuerte "elektrische Dämpfung" überlagert werden.The torsional damping device may be, for example, a friction torsion damping device, a hydrodynamic damping device or a damping device formed by one or more elastomers. An additional torsional vibration damping can be achieved in generator operation of the electric machine by an active control of the electric machine. The mechanical damping can thus be superimposed on the "electrical damping" controlled by the current flowing through the electrical machine.

Zusammenfassend werden mit der Erfindung insbesondere folgende Vorteile erreicht:

  • – Auf einen Schwingungsdämpfer in Form einer separaten Komponente kann aufgrund der "konstruktiven Verschmelzung" des Schwingungsdämpfers mit der Kurbelwelle und dem Rotor der elektrischen Maschine verzichtet werden.
  • – Die Massenträgheit der Gesamtanordnung ist dadurch vergleichsweise gering.
  • – Die elektrische Maschine und die Torsionsschwingungsdämpfungseinrichtung können in einen Antriebsstrang integriert werden, ohne dass das Getriebe oder die Abtriebsseite des Verbrennungsmotors geändert werden müssen.
  • – Im Vergleich zu herkömmlichen Hybridkonzepten wird kaum zusätzlicher Bauraum in Fahrzeuglängsrichtung benötigt.
  • – Im generatorischen Betrieb kann die elektrische Maschine als "aktiver Zusatzdämpfer" genutzt werden.
In summary, the invention achieves the following advantages in particular:
  • - On a vibration damper in the form of a separate component can be dispensed with due to the "constructive merger" of the vibration damper with the crankshaft and the rotor of the electric machine.
  • - The inertia of the overall arrangement is characterized comparatively low.
  • - The electric machine and the torsional vibration damping device can be integrated into a drive train without the transmission or the output side of the internal combustion engine must be changed.
  • - Compared to conventional hybrid concepts hardly additional space in the vehicle longitudinal direction is needed.
  • - In generator mode, the electric machine can be used as an "active additional damper".

Im Folgenden wird die Erfindung im Zusammenhang mit der Zeichnung näher erläutert. Die einzige 1 zeigt das Grundprinzip der Erfindung.In the following the invention will be explained in connection with the drawing. The only 1 shows the basic principle of the invention.

Auf einer dem Automatikgetriebe 2 gegenüberliegenden Seite des Verbrennungsmotors 1 ist eine elektrische Innenläufermaschine 3 angeordnet, die einen Stator 4 und einen radial innerhalb des Stators 4 angeordneten Rotor 5 aufweist. 1 shows a cost-effective concept for a hybrid vehicle with an internal combustion engine 1 and a - similar to conventional vehicles - directly to the output side of the internal combustion engine 1 flanged automatic transmission 2 , On one the automatic transmission 2 opposite side of the internal combustion engine 1 is an electric internal rotor machine 3 arranged, which is a stator 4 and one radially inside the stator 4 arranged rotor 5 having.

Radial innerhalb des Rotors 5 ist eine Torsionsdämpfungseinrichtung 6 angeordnet. Über die Torsionsdämpfungseinrichtung 6 ist der Rotor 5 mit dem "vorderen Ende" einer Kurbelwelle 7 des Verbrennungsmotors gekoppelt. Die Torsionsdämpfungseinrichtung 6 ist dazu vorgesehen, die bei bestimmten Antriebsstrangdrehzahlen auftretenden Torsionsresonanzen zu dämpfen.Radial inside the rotor 5 is a torsional damping device 6 arranged. About the torsional damping device 6 is the rotor 5 with the "front end" of a crankshaft 7 coupled to the internal combustion engine. The torsion damping device 6 is intended to dampen the torsional resonances occurring at certain powertrain speeds.

Durch die Kombination der Anordnung der elektrischen Maschine 3 auf der "Vorderseite" des Verbrennungsmotors 1 und durch die Anordnung der Torsionsdämpfungseinrichtung 6 innerhalb des von der elektrischen Maschine 3 eingenommen Bauraumbereichs ist in konstruktiv einfacher Weise ein Hybridfahrzeugkonzept darstellbar und zwar ohne dass das Getriebe 2 bzw. das getriebeseitige Ende des Verbrennungsmotors 1 geändert werden müssen.By combining the arrangement of the electric machine 3 on the "front" of the internal combustion engine 1 and by the arrangement of the torsion damping device 6 inside of the electric machine 3 occupied space space is in a structurally simple way a hybrid vehicle concept represented and that without the transmission 2 or the transmission-side end of the internal combustion engine 1 need to be changed.
