Description

Die Erfindung betrifft einen Antriebsstrang für ein Hybrid-Kraftfahrzeug mit einem Verbrennungsmotor, mindestens einem Elektromotor, mindestens einer Kupplungsanordnung und mindestens einer Getriebeanordnung und einer Speicheranordnung, die antriebstechnisch derart angeordnet sind, dass mindestens eine Antriebsachse antreibbar ist und wobei ein weiterer zweiter Elektromotor vorgesehen ist, der als Riemen-Starter-Generator ausgebildet ist und der einen Klimakompressor antreibt und der über eine Rotorwelle und eine zweite Kupplungsanordnung antriebstechnisch mit einer Kurbelwelle des Verbrennungsmotors verbindbar ist. The invention relates to a drive train for a hybrid motor vehicle having an internal combustion engine, at least one electric motor, at least one clutch arrangement and at least one transmission arrangement and a memory arrangement, which are arranged such that at least one drive axle can be driven and wherein a further second electric motor is provided. which is designed as a belt starter generator and which drives an air conditioning compressor and the drive via a rotor shaft and a second clutch assembly is connected to a crankshaft of the internal combustion engine.

Ein derartiger Antriebsstrang ist beispielsweise aus der DE 10 2011 056 431 A1 bekannt. Diese Druckschrift zeigt die Möglichkeit, eine Elektromaschine, die als Riemen-Starter-Generator ausgeführt ist, über ein variables Getriebe, beispielsweise einen Riementrieb, mit einer Kurbelwelle des Verbrennungsmotors antriebstechnisch zu verbinden, um die Drehzahl des Elektromotors im generatorischen Betrieb bedarfsgerecht stufenlos einstellen zu können. Such a drive train is for example from the DE 10 2011 056 431 A1 known. This publication shows the possibility of an electric machine, which is designed as a belt starter generator, via a variable transmission, such as a belt drive, to drively connect with a crankshaft of the internal combustion engine to adjust the speed of the electric motor as needed in regenerative operation can ,

Darüber hinaus kann dieser Elektromotor auch noch ein Nebenaggregat, beispielsweise einen Klimakompressor, antreiben. Auf diese Weise ist sichergestellt, dass auch bei einer rein elektrischen Fahrt mittels des ersten Elektromotors eine Klimatisierung des Kraftfahrzeuges möglich ist. Gerade im Falle einer längeren rein elektrischen Fahrt kann dies dazu führen, dass eine elektrische Speicheranordnung, beispielsweise eine Hochspannungsquelle, sehr stark belastet ist und der Verbrennungsmotor rechtzeitig wieder gestartet werden muss, um nicht Gefahr zu laufen, dass nicht mehr genügend Strom für die Starterfunktion zur Verfügung steht. In addition, this electric motor can also drive an auxiliary unit, for example an air conditioning compressor. In this way it is ensured that even with a purely electric drive by means of the first electric motor, an air conditioning of the motor vehicle is possible. Especially in the case of a longer purely electric drive, this can lead to an electrical storage device, such as a high voltage source is very heavily loaded and the engine must be restarted in good time, so as not to run the risk that not enough power for the starter function Available.

Der Erfindung liegt die Aufgabe zugrunde, den oben genannten Nachteil auf möglichst kostengünstige und konstruktiv einfache Weise zu überwinden. The invention has for its object to overcome the above drawback in the most cost-effective and structurally simple way.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Rotorwelle des zweiten Elektromotors eine Schwungmasse aufweist. Hierdurch ist es möglich, die im Schwungrad gespeicherte kinetische Energie dahingehend zu nutzen, dass bei zu startendem Verbrennungsmotor die zweite Kupplungsanordnung geschlossen wird und demensprechend der Verbrennungsmotor gestartet wird. This object is achieved in that the rotor shaft of the second electric motor has a flywheel. This makes it possible to use the kinetic energy stored in the flywheel to the effect that when the internal combustion engine to start the second clutch assembly is closed and demensprechend the internal combustion engine is started.

In einer besonders vorteilhaften Ausführungsform ist die Schwungmasse als Schwungrad oder Schwungscheibe ausgebildet. Die zweite Kupplungsanordnung kann auf einfache und vorteilhafte Weise als Magnetkupplung ausgeführt sein, alternativ aber auch elektromechanisch oder elektrohydraulisch aktuiert sein. Auch ist es möglich, dass der zweite Elektromotor und der Klimakompressor in einem Gehäuse angeordnet sind. In a particularly advantageous embodiment, the flywheel is designed as a flywheel or flywheel. The second clutch assembly may be designed in a simple and advantageous manner as a magnetic coupling, but alternatively be electromechanically or electrohydraulically actuated. It is also possible that the second electric motor and the air compressor are arranged in a housing.

Die Erfindung wird anhand einer Zeichnung näher erläutert, hierbei zeigt: The invention will be explained in more detail with reference to a drawing, in which:

1 eine schematische Ansicht eines erfindungsgemäßen Antriebsstranges, und 1 a schematic view of a drive train according to the invention, and

2 eine schematische Seitenansicht eines elektrischen Klimakompressors mit einem zweiten Elektromotor und einer zweiten Kupplungsanordnung. 2 a schematic side view of an electric air conditioning compressor with a second electric motor and a second clutch assembly.

1 zeigt einen Antriebsstrang 2 für ein nicht weiter dargestelltes Hybrid-Kraftfahrzeug. Der Antriebsstrang 2 weist auf bekannte Weise einen Verbrennungsmotor 4, einen ersten Elektromotor 6 sowie eine Steuereinrichtung 10 auf. Hierbei ist der Verbrennungsmotor 4 auf bekannte Weise über eine erste Kupplungsanordnung 12 mit einer Getriebeanordnung 14 derart gekoppelt, dass eine Kraftübertragung auf eine nicht weiter dargestellte Antriebsachse möglich ist. Auch über den Elektromotor 6 ist auf bekannte Weise der Antrieb einer Antriebsachse möglich. 1 shows a drive train 2 for a not further shown hybrid motor vehicle. The powertrain 2 has a known manner an internal combustion engine 4 , a first electric motor 6 and a control device 10 on. Here is the internal combustion engine 4 in a known manner via a first clutch arrangement 12 with a gear arrangement 14 so coupled that a power transmission to a drive axle, not shown, is possible. Also about the electric motor 6 is possible in a known manner the drive of a drive axle.

Des Weiteren ist ein als Riemen-Starter-Generator ausgeführter Elektromotor 8 vorgesehen, der im vorliegenden Ausführungsbeispiel über einen als Getriebe ausgeführten Riementrieb 16 mit einer Kurbelwelle 18 des Verbrennungsmotors 4 antriebstechnisch verbunden ist. Hierbei ist zwischen dem zweiten Elektromotor 8 und dem Riementrieb 16 eine zweite Kupplungsanordnung 20 vorgesehen, um den zweiten Elektromotor 8 auf einfache Weise von der Kurbelwelle 18 entkoppeln zu können. Dies ist beispielsweise dann notwendig, wenn der zweite Elektromotor nicht als Generator arbeiten soll, sondern ein als Klimakompressor 22 ausgeführtes Nebenaggregat antreibt. Um nun den Verbrennungsmotor 4 auf einfache Weise wieder starten zu können, weist eine Rotorwelle 24 des zweiten Elektromotors 8 eine Schwungmasse 26 auf. Hierdurch kann über die kinetische Energie der Schwungmasse 26 nach dem Einkuppelvorgang der zweiten Kupplungsanordnung 20 der Verbrennungsmotor 4 einfacher gestartet werden. Furthermore, a designed as a belt starter generator electric motor 8th provided, in the present embodiment via a belt drive designed as a transmission 16 with a crankshaft 18 of the internal combustion engine 4 drive technology is connected. Here is between the second electric motor 8th and the belt drive 16 a second clutch assembly 20 provided to the second electric motor 8th in a simple way from the crankshaft 18 to decouple. This is necessary, for example, if the second electric motor should not work as a generator, but rather as an air-conditioning compressor 22 engineered accessory drives. To now the internal combustion engine 4 easy to start again, has a rotor shaft 24 of the second electric motor 8th a flywheel 26 on. This allows the kinetic energy of the flywheel 26 after the engagement of the second clutch assembly 20 the internal combustion engine 4 easier to start.

2 zeigt nun in einer Seitenansicht den zweiten Elektromotor 8 und den Klimakompressor 22, die in einem Gehäuse 28 angeordnet sind. Die Rotorwelle 24 weist die als Schwungscheibe ausgeführte Schwungmasse 26 auf. Mit 30 ist eine Riemenscheibe des Riementriebs 16 angedeutet, der über die als Magnetkupplung ausgeführte zweite Kupplungsanordnung ein- oder ausgekuppelt werden kann. 2 now shows in a side view the second electric motor 8th and the air conditioning compressor 22 in a housing 28 are arranged. The rotor shaft 24 has the flywheel designed as a flywheel 26 on. With 30 is a pulley of the belt drive 16 indicated that can be switched on or disengaged via the designed as a magnetic coupling second clutch assembly.
