Description
Die Erfindung betrifft einen Antriebsstrang für ein Hybridfahrzeug mit einer Verbrennungskraftmaschine, mindestens einer elektrischen Maschine, einer Doppelkupplungseinrichtung, einer Getriebeeingangswelle, wobei mindestens einer elektrischen Maschine, einer Doppelkupplungseinrichtung, einer Getriebeeingangswelle, auf die das Drehmoment der beiden Antriebe über die Doppelkupplungseinrichtung wahlweise übertragen wird, sowie mindestens eine Getriebeausgangswelle.The invention relates to a drive train for a hybrid vehicle with an internal combustion engine, at least one electric machine, a double clutch device, a transmission input shaft, with at least one electric machine, a double clutch device, a transmission input shaft to which the torque of the two drives is optionally transmitted via the double clutch device, as well as at least one transmission output shaft.
Bei einem bekannten Hybridmodul (
Ferner ist ein Antriebsstrang für ein Hybridfahrzeug bekannt (
Der Erfindung liegt die Aufgabe zugrunde, einen Antriebsstrang für ein Hybridfahrzeug zu schaffen, das eine geringe Baulänge und eine reduzierte Anzahl von Bauteilen aufweist. Darüber hinaus sollen in dem Antriebsstrang mindestens zwei Vorwärtsgänge vorgesehen sein, die elektrisch, verbrennungsmotorisch sowie kombiniert gefahren werden können, wobei die Schaltung zumindest vom ersten in den zweiten Gang zugkraftunterbrechungsfrei vonstattengehen soll.The invention is based on the object of creating a drive train for a hybrid vehicle that has a short overall length and a reduced number of components. In addition, at least two forward gears should be provided in the drive train, which can be driven electrically, with the internal combustion engine and in combination, whereby the shift from first to second gear should take place without interruption of traction.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass zwei Getriebeausgangswellen vorgesehen sind, auf denen je ein als Festrad ausgebildetes Abtriebszahnrad sitzt, das mit dem Differentialzahnrad des Differentialgetriebes im Eingriff steht, dass das Antriebszahnrad der elektrischen Maschine mit einem auf der Getriebeeingangswelle sitzenden ersten Losrad mittelbar oder unmittelbar im Eingriff steht, dass dieses erste Losrad einerseits mit der Doppelkupplungseinrichtung verbunden ist und andererseits mit einem auf der ersten Getriebeausgangswelle sitzenden zweiten Losrad im Eingriff steht, dass dieses zweite Losrad über einen Freilauf mit einem weiteren, auf der ersten Getriebeausgangswelle sitzenden dritten Losrad in Verbindung steht, dass das dritte Losrad mit einem auf der Getriebeeingangswelle sitzenden ersten Festrad im Eingriff steht, dass dieses Festrad mittelbar oder unmittelbar mit einem auf der zweiten Getriebeausgangswelle sitzenden vierten Losrad in Verbindung steht und dass dieses Losrad mittels einer auf der zweiten Getriebeausgangswelle angeordneten ersten Schaltmuffe fest mit der zweiten Getriebeausgangswelle verbindbar ist.According to the invention, this object is achieved in that two transmission output shafts are provided, on each of which there is an output gear designed as a fixed gear, which is in engagement with the differential gear of the differential gear, that the drive gear of the electrical machine directly or indirectly with a first idler gear seated on the transmission input shaft What is engaged is that this first idler gear is connected on the one hand to the dual clutch device and on the other hand it is in engagement with a second idler gear seated on the first transmission output shaft, so that this second idler gear is connected via a freewheel to a further third idler gear seated on the first gearbox output shaft that the third idler gear is in engagement with a first fixed gear seated on the transmission input shaft, that this fixed gear is directly or indirectly connected to a fourth idler gear seated on the second gearbox output shaft, and there This idler gear can be firmly connected to the second transmission output shaft by means of a first shift sleeve arranged on the second transmission output shaft.
Durch die Erfindung wird eine neue Getriebearchitektur geschaffen, die mindestens zwei Vorwärtsgänge bietet, die elektrisch, verbrennungsmotorisch oder kombiniert gefahren werden können. Dabei ist gewährleistet, dass die Schaltung vom ersten in den zweiten Gang zugkraftunterbrechungsfrei vonstattengeht. Hinzukommt, dass die Baulänge des Getriebes und die Anzahl der Bauteile auf ein Minimum reduziert wird, sodass die Kosten des Getriebes erheblich reduziert werden können und man sehr flexibel auf die Platzsituationen in den Motorräumen eingehen kann. Durch die gewählte Anordnung der Kupplung und des Freilaufs sowie der weiteren erfindungsgemäßen Merkmale ist es gelungen, mit nur zwei Kupplungen auszukommen, wobei sämtliche Gänge elektrisch und/oder verbrennungsmotorisch gefahren werden können.The invention creates a new transmission architecture that offers at least two forward gears that can be driven electrically, with an internal combustion engine or in combination. This ensures that the shift from first to second gear takes place without interruption of tractive effort. In addition, the overall length of the transmission and the number of components are reduced to a minimum, so that the costs of the transmission can be reduced considerably and the space situations in the engine compartments can be dealt with very flexibly. The selected arrangement of the clutch and the freewheel and the other features according to the invention have made it possible to manage with only two clutches, with all gears being able to be driven electrically and / or by an internal combustion engine.
Bei Fahrzeugen, deren Geschwindigkeit auf beispielsweise ca. 140 km/h beschränkt ist, reichen diese beiden Gänge aus. Werden höhere Geschwindigkeiten gefordert, so kann der Antriebsstrang auf 3 oder 4 Gänge erweitert werden. Auf diese Weise ist das erfindungsgemäße Konzept für eine große Anzahl von Fahrzeugtypen verwendbar.For vehicles whose speed is limited to approx. 140 km / h, for example, these two gears are sufficient. If higher speeds are required, the drive train can be extended to 3 or 4 gears. In this way, the concept according to the invention can be used for a large number of vehicle types.
Um den erfindungsgemäßen Antriebsstrang auf 3 oder 4 Gänge zu erweitern, steht das erste Festrad, welches auf der Getriebeeingangswelle angeordnet ist, vorzugsweise mit einem auf der zweiten Getriebeausgangswelle sitzenden fünften Losrad im Eingriff.In order to expand the drive train according to the invention to 3 or 4 gears, the first fixed gear, which is arranged on the transmission input shaft, preferably meshes with a fifth idler gear located on the second transmission output shaft.
Dabei kann die auf der zweiten Getriebeausgangswelle angeordnete Schaltmuffe zweiseitig wirkend ausgebildet sein, sodass wahlweise entweder das vierte Losrad der zweiten Getriebeausgangswelle oder das benachbarte, ebenfalls auf der zweiten Getriebeausgangswelle sitzende fünfte Losrad fest mit der zweiten Getriebeausgangswelle verbunden werden kann. Der Kraftfluss verläuft dann folglich ebenso wie bei den beiden ersten Gängen über das auf der zweiten Getriebeausgangswelle sitzende Abtriebszahnrad auf das Differentialzahnrad des Differentialgetriebes.The shift sleeve arranged on the second transmission output shaft can be designed to act on both sides so that either the fourth idler gear of the second transmission output shaft or the adjacent fifth idler gear, which is also located on the second transmission output shaft, can be firmly connected to the second transmission output shaft. As in the case of the first two gears, the power flow then runs via the output gear, which is seated on the second gear output shaft, to the differential gear of the differential gear.
Die Doppelkupplungseinrichtung weist zwei Teilkupplungen auf, wobei die erste Teilkupplung zweckmäßig zur Verbindung der Verbrennungskraftmaschine mit der Getriebeeingangswelle und die zweite Teilkupplung zur Verbindung der elektrischen Maschine mit der Getriebeeingangswelle vorgesehen ist. Auf diese Weise kann zumindest die Schaltung vom ersten Gang in den zweiten Gang zugkraftunterbrechungsfrei vonstattengehen.The double clutch device has two partial clutches, the first partial clutch being expediently provided for connecting the internal combustion engine to the transmission input shaft and the second partial clutch for connecting the electrical machine to the transmission input shaft. In this way, at least the shift from first gear to second gear can take place without interruption of tractive force.
Bei Betätigung beider Teilkupplungen der Doppelkupplungseinrichtung kann sowohl die Verbrennungskraftmaschine als auch die elektrische Maschine auf die Getriebeeingangswelle zugeschaltet werden, sodass sämtliche Antriebsvarianten, also entweder über die Verbrennungskraftmaschine oder die elektrische Maschine oder auch kombiniert möglich sind.When both partial clutches of the double clutch device are actuated, both the internal combustion engine and the electric machine can be switched on to the transmission input shaft, so that all drive variants, i.e. either via the internal combustion engine or the electric machine or also in combination, are possible.
Bei dem erfindungsgemäßen Antriebsstrang lässt sich auch problemlos ein Rückwärtsgang zuschalten. Dabei kann für den Rückwärtsgang auf der ersten Getriebeausgangswelle ein sechstes Losrad angeordnet sein, welches mit dem auf der zweiten Getriebeausgangswelle angeordneten vierten Losrad im Eingriff steht. Das für den Rückwärtsgang vorgesehene sechste Losrad kann dann mittels einer auf der ersten Getriebeausgangswelle angeordneten zweiten Schaltmuffe wahlweise ein- oder auskuppelbar sein, wobei der Kraftfluss über die erste Getriebeausgangswelle und das auf dieser sitzende Abtriebszahnrad auf das Differentialzahnrad übertragen wird. Die übrigen im Eingriff stehenden Zahnradpaarungen laufen dabei leer mit.In the drive train according to the invention, a reverse gear can also be engaged without any problems. For the reverse gear, a sixth idler gear can be arranged on the first transmission output shaft, which is in engagement with the fourth idler gear arranged on the second transmission output shaft. The sixth idler gear provided for the reverse gear can then be selectively engaged or disengaged by means of a second shift sleeve arranged on the first transmission output shaft, the power flow being transmitted to the differential gear via the first transmission output shaft and the output gear seated on it. The other meshing gear pairs run along idle.
Auf der zweiten Getriebeausgangswelle kann ferner ein für die Parkstellung vorgesehenes weiteres Festrad angeordnet sein.A further fixed gear provided for the parking position can also be arranged on the second transmission output shaft.
