Abstract
Die Erfindung betrifft einen Hybridantriebsstrang für ein Kraftfahrzeug mit einer mit einem Energiespeicher (3) verbundenen elektrischen Maschinen (1) sowie mit einer Verbrennungskraftmaschine (2), wobei beide Antriebe nach Art eines leistungsverzweigten Hybrids mit dem Differentialzahnrad (4) eines zu den Antriebsrädern des Kraftfahrzeugs führenden Differentialgetriebes (5) verbindbar sind. Ein solcher Antriebsstrang soll einfacher im Aufbau gestaltet werden und einen geringeren Leistungsverlust bewirken. Dies wird gemäß der Erfindung dadurch erreicht, dass in den Antriebsstrang mindestens zwei Zwischenwellen (6, 7) vorgesehen sind, dass die erste Zwischenwelle (6) von der elektrischen Maschine (1) und die zweite Zwischenwelle (7) von der Verbrennungskraftmaschine (2) antreibbar ist, dass auf den Zwischenwellen (6, 7) mindestens je ein als Losrad ausgebildetes Abtriebszahnrad (8; 9) vorgesehen ist, das über eine Kupplungseinrichtung (10; 11) auf der jeweiligen Zwischenwelle (6; 7) festlegbar ist, und dass die Abtriebszahnräder (8, 9) gemeinsam oder wahlweise mit dem Differentialzahnrad (4) des Differentialgetriebes (5) verbindbar sind.The invention relates to a hybrid drive train for a motor vehicle with an electrical machine (1) connected to an energy store (3) and with an internal combustion engine (2), both drives in the manner of a power-split hybrid with the differential gear (4) one to the drive wheels of the motor vehicle leading differential gear (5) are connectable. Such a drive train should have a simpler structure and result in a lower loss of power. According to the invention, this is achieved in that at least two intermediate shafts (6, 7) are provided in the drive train, the first intermediate shaft (6) from the electrical machine (1) and the second intermediate shaft (7) from the internal combustion engine (2) it is drivable that at least one driven gear wheel (8; 9) designed as an idler gear is provided on each of the intermediate shafts (6, 7) and can be fixed on the respective intermediate shaft (6; 7) via a coupling device (10; 11), and that the output gears (8, 9) can be connected jointly or optionally with the differential gear (4) of the differential gear (5).
Description
Die Erfindung betrifft einen Hybridantriebsstrang für ein Kraftfahrzeug mit einer mit einem Energiespeicher verbundenen elektrischen Maschinen sowie mit einer Verbrennungskraftmaschine, wobei beide Antriebe nach Art eines leistungsverzweigten Hybrids mit dem Differentialzahnrad eines zu den Antriebsrädern des Kraftfahrzeugs führenden Differentialgetriebes verbindbar sind.The invention relates to a hybrid drive train for a motor vehicle with an electrical machine connected to an energy store and with an internal combustion engine, both drives being connectable in the manner of a power-split hybrid with the differential gear of a differential gear leading to the drive wheels of the motor vehicle.
Bei bekannten Hybridantriebssträngen der genannten Art (beispielsweise
Der Erfindung liegt daher die Aufgabe zugrunde, einen Hybridantriebsstrang zu schaffen, der einfacher im Aufbau ist und bezüglich der vorhandenen Getriebeteile einen geringeren Leistungsverlust bewirkt.The invention is therefore based on the object of creating a hybrid drive train which is simpler in structure and causes a lower loss of power with respect to the transmission parts present.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass in den Antriebsstrang mindestens zwei Zwischenwellen vorgesehen sind, dass die erste Zwischenwelle von der elektrischen Maschine und die zweite Zwischenwelle von der Verbrennungskraftmaschine antreibbar ist, dass auf den Zwischenwellen mindestens je ein als Losrad ausgebildetes Abtriebszahnrad vorgesehen ist, das über eine Kupplungseinrichtung auf der jeweiligen Zwischenwelle festlegbar ist, und dass die Abtriebszahnräder gemeinsam oder wahlweise mit dem Differentialzahnrad des Differentialgetriebes verbindbar sind.According to the invention, this object is achieved in that at least two intermediate shafts are provided in the drive train, that the first intermediate shaft can be driven by the electrical machine and the second intermediate shaft can be driven by the internal combustion engine, that at least one output gear designed as a loose wheel is provided on each of the intermediate shafts can be fixed via a coupling device on the respective intermediate shaft, and that the output gears can be connected jointly or alternatively with the differential gear of the differential gear.
Bei Verwendung des erfindungsgemäßen Hybridantriebsstrang kann demnach auf ein Planetengetriebe völlig verzichtet werden, indem
Die Ausgangswelle der elektrischen Maschine und die Ausgangswelle der Verbrennungskraftmaschine werden vorzugsweise über schaltbare Zahnradpaare mit den Zwischenwellen verbunden, sodass diverse Schaltmöglichkeiten erzielt werden können.The output shaft of the electrical machine and the output shaft of the internal combustion engine are preferably connected to the intermediate shafts via switchable gear pairs so that various switching options can be achieved.
Bei einem vorteilhaften Ausführungsbeispiel können auf der Ausgangswelle der elektrischen Maschine zwei Losräder angeordnet sein, die mit Hilfe von mindestens einer Kupplungseinrichtung wahlweise festlegbar sind. Dabei kann beispielsweise eine zweiseitig wirkende Kupplungseinrichtung verwendet werden, mit der beide Losräder abwechselnd mit der Ausgangswelle der elektrischen Maschine verbunden werden können.In an advantageous embodiment, two idler gears can be arranged on the output shaft of the electrical machine, which idler gears can be selectively fixed with the aid of at least one clutch device. For example, a double-acting coupling device can be used with which the two idler gears can be alternately connected to the output shaft of the electrical machine.
Die beiden auf der Ausgangswelle der Verbrennungskraftmaschine angeordneten Losräder können mit Losrädern der zweiten Zwischenwelle kämmen, wobei diese auf der zweiten Zwischenwelle sitzenden Losräder mit Hilfe von mindestens einer Kupplungseinrichtung auf der zweiten Zwischenwelle wahlweise festlegbar sind. Auch bei dieser Konstellation können zweiseitig wirkende Kupplungseinrichtungen verwendet werden, mit denen beide Losräder abwechselnd mit der Ausgangswelle der Verbrennungskraftmaschine verbindbar sind. Alternativ können selbstverständlich auch einseitig wirkende Kupplungseinrichtungen verwendet werden, die jeweils einzeln ein Losrad bedienen.The two idler gears arranged on the output shaft of the internal combustion engine can mesh with idler gears of the second intermediate shaft, these idler gears seated on the second intermediate shaft being selectively fixable on the second intermediate shaft with the help of at least one coupling device. In this constellation, too, coupling devices acting on both sides can be used, with which both idler gears can be alternately connected to the output shaft of the internal combustion engine. Alternatively, coupling devices acting on one side can of course also be used, each of which individually serves a loose wheel.
Mit Hilfe eines solchen Antriebsstrangs können jeweils zwei Gänge sowohl von der elektrischen Maschine aus als auch von der Verbrennungskraftmaschine aus erzeugt werden.With the help of such a drive train, two gears can be generated both from the electrical machine and from the internal combustion engine.
Bei einem anderen Ausführungsbeispiel kann auf mindestens einer der beiden Zwischenwellen ein Festrad angeordnet sein, das mit einem festlegbaren Losrad einer der Ausgangswellen der elektrischen Maschine bzw. der Verbrennungskraftmaschine kämmt. Auf diese Weise kann ein zusätzlicher Gang, ggf. in Form eines Verwindungsgangs, erzeugt werden.In another exemplary embodiment, a fixed wheel can be arranged on at least one of the two intermediate shafts, which fixed wheel meshes with a definable idler wheel of one of the output shafts of the electrical machine or the internal combustion engine. In this way, an additional path, possibly in the form of a twisting path, can be generated.
Ein weiterer Gang, ggf. als Verwindungsgang, wird dadurch ermöglicht, dass auf beiden Zwischenwellen je ein Festrad angeordnet ist, das mit je einem festlegbaren Losrad der Ausgangswelle der elektrischen Maschine bzw. der Verbrennungskraftmaschine kämmt. Insofern ist es dann möglich, vier Gänge seitens der elektrischen Maschine und weitere vier Gänge seitens der Verbrennungskraftmaschine zu erzeugen.Another gear, possibly as a twisting gear, is made possible by a fixed gear being arranged on each of the two intermediate shafts, which meshes with a definable idler gear on the output shaft of the electrical machine or the internal combustion engine. In this respect, it is then possible to generate four gears on the part of the electrical machine and a further four gears on the part of the internal combustion engine.
Bei einem weiteren Ausführungsbeispiel des erfindungsgemäßen Hybridantriebsstrangs kann das Differentialgetriebe mindestens zwei Differentialzahnräder aufweisen, während auf den Zwischenwellen mindestens zwei Abtriebszahnräder angeordnet sind, von denen jedes mit einem der Differentialzahnräder im Eingriff steht. Dabei sind die Abtriebszahnräder als wahlweise mit Hilfe von Kupplungseinrichtungen festlegbare Losräder ausgebildet.In a further embodiment of the hybrid drive train according to the invention, the differential gear can have at least two differential gears, while at least two output gears are arranged on the intermediate shafts, each of which meshes with one of the differential gears. The output gears are designed as loose gears that can be optionally fixed with the aid of coupling devices.
Eine weitere Variante des erfindungsgemäßen Hybridantriebsstrangs kann darin bestehen, dass eine ständig oder wahlweise angetriebene dritte Zwischenwelle vorgesehen ist, auf der ebenfalls zwei wahlweise mittels einer Kupplungseinrichtung festlegbare Abtriebszahnräder angeordnet sind, die mit den beiden Differentialzahnrädern kämmen.A further variant of the hybrid drive train according to the invention can consist in that a third intermediate shaft, which is continuously or optionally driven, is provided on the likewise two output gears which can be fixed optionally by means of a coupling device and which mesh with the two differential gears.
