Description
Die Erfindung betrifft einen Antriebstrang für ein Fahrzeug mit einer Brennkraftmaschine, mit zumindest einer elektrischen Maschine, deren Motorwelle mit einer Antriebswelle der Brennkraftmaschine über ein mechanisches Getriebe antriebsverbindbar ist, sowie mit zumindest einem zwischen Brennkraftmaschine und elektrischer Maschine im Antriebstrang angeordneten Plantetengetriebe, welches die Planetengetriebeelemente Sonnenrad, Hohlrad und Planetenträger mit zumindest einem Planetenrad aufweist, wobei die elektrische Maschine über zumindest eine Kupplungseinrichtung mit dem Planetengetriebe antriebsverbindbar ist, wobei wahlweise zwei der drei Planetengetriebeelemente Sonnenrad, Planetenträger und Hohlrad, vorzugsweise der Planetenträger und das Hohlrad, über die Kupplungseinrichtung drehverbindbar sind und wobei eines der Planetengetriebeelemente über eine Bremseinrichtung fixierbar ist, und wobei die Antriebswelle der Brennkraftmaschine und die Motorwelle der elektrischen Maschine parallel zueinander, insbesondere auf der selben Seite in Bezug auf das mechanische Getriebe angeordnet sind, wobei das mechanische Getriebe als Formschlussgetriebe mit konstanter Übersetzung, vorzugsweise als Stirnradgetriebe, ausgebildet ist. The invention relates to a drive train for a vehicle with an internal combustion engine, with at least one electric machine, the motor shaft is drive-connected with a drive shaft of the internal combustion engine via a mechanical transmission, as well as at least one disposed between the engine and electric machine in the drive train planetary gear which sun gear planetary gear elements , Ring gear and planet carrier having at least one planetary gear, wherein the electric machine via at least one coupling device with the planetary gear is drive-connected, wherein optionally two of the three planetary gear sun gear, planet carrier and ring gear, preferably the planet carrier and the ring gear, are drehverbindbar via the coupling means and wherein one of the planetary gear elements is fixable via a brake device, and wherein the drive shaft of the internal combustion engine and the motor shaft of the electric machine ne parallel to each other, in particular on the same side with respect to the mechanical transmission are arranged, wherein the mechanical transmission is designed as a form-locking transmission with constant gear ratio, preferably as a spur gear.
Brennkraftmaschinen, welche mit sogenannten Downsizing-Konzepten ausgelegt sind, haben den Nachteil, dass die Reduktion der Zylinderzahl zu einer Erhöhung der Drehungsgleichförmigkeit der Brennkraftmaschine führt. Eine Erhöhung des Trägheitsmomentes der Schwungmasse ist aber nachteilig hinsichtlich Masse, Bauraum und Beschleunigungsverhalten. Internal combustion engines, which are designed with so-called downsizing concepts, have the disadvantage that the reduction in the number of cylinders leads to an increase in the rotational uniformity of the internal combustion engine. An increase in the moment of inertia of the flywheel is disadvantageous in terms of mass, space and acceleration behavior.

Aufgabe der Erfindung ist es, auf möglichst platzsparende Weise Drehungleichförmigkeiten in verschiedenen Betriebsbereichen der Brennkraftmaschine optimal auszugleichen, ohne das Beschleunigungsverhalten nachteilig zu beeinflussen. The object of the invention is optimally balanced in the most space-saving way rotational irregularities in different operating ranges of the internal combustion engine, without adversely affecting the acceleration behavior.
Erfindungsgemäß wird dies dadurch erreicht, dass die Kupplungseinrichtung eine erste Schaltkupplung aufweist und in das Planetengetriebe zumindest eine Schwungmasse integriert ist, wobei die Schwungmasse mit einem Planetengetriebeelement – vorzugsweise mit dem Hohlrad – fest verbunden oder einstückig mit diesem ausgebildet ist. According to the invention this is achieved in that the coupling device comprises a first clutch and in the planetary gear at least one flywheel is integrated, wherein the flywheel with a planetary gear element - preferably with the ring gear - firmly connected or formed integrally therewith.
Dabei kann die elektrische Maschine in Abhängigkeit der auszugleichenden Drehungleichförmigkeiten motorisch oder generatorisch variabel mit verschiedenen Drehzahlen betrieben werden, wobei vorzugsweise die erste Schaltkupplung ausgekuppelt und die Bremseinrichtung deaktiviert wird. Die Bremseinrichtung wird oder bleibt geöffnet. Über die Drehzahlvariation der ersten elektrischen Maschine stellt sich – zusammen mit der Schwungmasse im Planetengetriebe – die gewünschte Massenträgheit ein. In this case, depending on the rotational irregularities to be compensated, the electric machine can be variably operated at different rotational speeds by means of a motor or generator, wherein preferably the first clutch is disengaged and the brake device is deactivated. The braking device is or remains open. About the speed variation of the first electric machine adjusts - together with the flywheel in the planetary gear - the desired inertia.
Die Motorwelle der elektrischen Maschine kann fest mit einem ersten Planetengetriebeelement, vorzugsweise mit dem Sonnenrad, verbunden sein. Dies erlaubt eine sehr kompakte Anordnung des Antriebsstranges, insbesondere wenn ein zweites Planetengetriebeelement, vorzugsweise der Planetenträger, fest mit einer Zwischenwelle des mechanischen Getriebes verbunden ist. The motor shaft of the electric machine can be fixedly connected to a first planetary gear element, preferably to the sun gear. This allows a very compact arrangement of the drive train, in particular when a second planetary gear element, preferably the planet carrier, is fixedly connected to an intermediate shaft of the mechanical transmission.
Das mechanische Getriebe ist vorzugsweise im Antriebsweg zwischen Brennkraftmaschine und einem Verstellgetriebe, vorzugsweise einem Schaltgetriebe angeordnet, wobei vorzugsweise zwischen dem mechanischen Getriebe und dem Verstellgetriebe eine zweite Schaltkupplung angeordnet ist, um den Antriebsstrang vom Verstellgetriebe und den Antriebsrädern zu trennen. The mechanical transmission is preferably arranged in the drive path between the internal combustion engine and an adjusting mechanism, preferably a manual transmission, preferably between the mechanical transmission and the adjusting a second clutch is arranged to separate the drive train from the adjusting and the drive wheels.
Um das Fahrzeug rein elektrisch durch die erste elektrische Maschine antreiben zu können, kann in weiterer Ausgestaltung der Erfindung vorgesehen sein, dass im Antriebsweg zwischen Brennkraftmaschine und mechanischem Getriebe eine dritte Schaltkupplung angeordnet ist, mit welcher die Brennkraftmaschine vom übrigen Antriebstrang getrennt werden kann. In order to drive the vehicle purely electrically by the first electric machine, the invention can be provided in a further embodiment that in the drive path between the engine and mechanical transmission, a third clutch is arranged, with which the engine can be separated from the rest of the drive train.
Dadurch ist es möglich, die elektrische Maschine nicht nur als Generator oder als Starter zum Anlassen der Brennkraftmaschine, sondern zum Antrieb des Fahrzeuges zu verwenden. Durch Auskuppeln der dritten Schaltkupplung ist somit ein elektrischer Betrieb möglich. This makes it possible to use the electric machine not only as a generator or as a starter for starting the internal combustion engine, but to drive the vehicle. By disengaging the third clutch thus electrical operation is possible.
Dabei kann auch in zumindest einem Betriebsbereich des Fahrzeuges über die motorisch betriebene elektrische Maschine zur Unterstützung der Brennkraftmaschine ein zusätzliches Antriebsmoment zum Antrieb des Fahrzeuges zur Verfügung gestellt wird, wobei die erste Schaltkupplung eingekuppelt und die Bremseinrichtung deaktiviert oder die erste Schaltkupplung ausgekuppelt und die Bremseinrichtung aktiviert wird. In this case, an additional drive torque for driving the vehicle is provided in at least one operating range of the vehicle via the motor-driven electric machine to support the internal combustion engine, wherein the first clutch engaged and disables the braking device or the first clutch disengaged and the braking device is activated ,
Mit der beschriebenen Anordnung lässt sich eine Lastpunktverschiebung der Brennkraftmaschine zur Optimierung des Gesamtwirkungsgrades und zur Ermöglichung einer geänderten Betriebsstrategie des Gesamtmanagements durchführen. With the described arrangement, a load point shift of the internal combustion engine can be carried out to optimize the overall efficiency and to enable a changed operating strategy of the overall management.
Mit der beschriebenen Konfiguration sind verschiedene Betriebsstrategien möglich, wobei vorzugsweise in einem ersten Betriebsbereich der Brennkraftmaschine die erste Schaltkupplung ausgekuppelt und die Bremseinrichtung aktiviert wird und in einem zweiten Betriebsbereich der Brennkraftmaschine die erste Schaltkupplung eingekuppelt und die Bremseinrichtung deaktiviert wird. Weiters kann in einem dritten Betriebsbereich der Brennkraftmaschine die erste Schaltkupplung ausgekuppelt und die Bremseinrichtung deaktiviert werden. With the described configuration, different operating strategies are possible, preferably in a first operating range of the internal combustion engine disengaged the first clutch and the braking device is activated and engaged in a second operating range of the internal combustion engine, the first clutch and the braking device is deactivated. Furthermore, in a third operating range of the internal combustion engine, the first clutch can be disengaged and the brake device can be deactivated.
Der erste Betriebsbereich der Brennkraftmaschine kann zumindest einem Bereich niedriger Drehzahl, vorzugsweise zwischen 1200 und 2000 U/min, und gleichzeitig hoher Teillast oder Volllast zugeordnet sein. Der zweite Betriebsbereich kann zumindest einem niedrigen oder mittleren Teillastbereich der Brennkraftmaschine mit hoher Drehzahl, vorzugsweise über 2000 U/min, zugeordnet werden. The first operating range of the internal combustion engine may be associated with at least a low speed range, preferably between 1200 and 2000 rpm, and at the same time a high part load or full load. The second operating range can be assigned to at least one low or medium part-load range of the high-speed internal combustion engine, preferably above 2000 rpm.
Weiters wird beim Startvorgang der Brennkraftmaschine die erste Schaltkupplung eingekuppelt und die zweite Schaltkupplung ausgekuppelt. Furthermore, the first clutch is engaged during the starting process of the internal combustion engine and the second clutch disengaged.
Weiters kann besonders vorteilhaft eine Rekuperation durchgeführt werden, wobei in Abhängigkeit des Ladezustandes des elektrischen Energiespeichers die erste Schaltkupplung eingekuppelt und die Bremseinrichtung deaktiviert oder die erste Schaltkupplung ausgekuppelt und die Bremseinrichtung aktiviert wird. Falls der Ladezustand ausreichend hoch ist, können sowohl die erste Schaltkupplung ausgekuppelt, als auch die Bremseinrichtung deaktiviert werden, wodurch Reibungsverluste vermieden werden können. Furthermore, a recuperation can be carried out particularly advantageously, the first clutch being engaged as a function of the state of charge of the electrical energy store and the braking device deactivated or the first clutch being disengaged and the braking device being activated. If the state of charge is sufficiently high, both the first clutch can be disengaged, and the braking device can be deactivated, whereby friction losses can be avoided.
Auf diese Weise können unterschiedliche Rekuperationspotentiale – steuerbar in Abhängigkeit des Ladezustandes des elektrischen Energiespeichers – realisiert werden. In this way, different recuperation potentials - controllable depending on the state of charge of the electrical energy storage - can be realized.
Ein optimaler Ausgleich der Drehungleichförmigkeiten kann durchgeführt werden, wenn die elektrische Maschine in Abhängigkeit der auszugleichenden Drehungleichförmigkeiten motorisch oder generatorisch variabel mit verschiedenen Drehzahlen betrieben wird, wobei die erste Schaltkupplung ausgekuppelt und die Bremseinrichtung deaktiviert werden. An optimal compensation of the rotational irregularities can be carried out when the electric machine is operated as a function of the rotational irregularities to be compensated variable by motor or generator at different speeds, wherein the first clutch disengaged and the braking device are deactivated.
