Description
Die vorliegende Erfindung betrifft einen Hybridantriebsstrang für ein Kraftfahrzeug, mit einer ersten Antriebseinheit zur Bereitstellung einer ersten Antriebsleistung zum Antreiben des Kraftfahrzeuges und mit einer zweiten Antriebseinheit zur Bereitstellung einer zweiten Antriebsleistung zum Antreiben des Kraftfahrzeuges, und mit einer Getriebeanordnung, die mit der ersten Antriebseinheit und mit der zweiten Antriebseinheit verbunden ist, um Antriebsleistung zu einem Getriebeausgang in unterschiedlichen Übersetzungen zu führen.The present invention relates to a hybrid drive train for a motor vehicle, with a first drive unit for providing a first drive power for driving the motor vehicle and with a second drive unit for providing a second drive power for driving the motor vehicle, and with a gear arrangement which is connected to the first drive unit and with the second drive unit is connected to lead drive power to a transmission output in different ratios.
Auf dem Gebiet der Hybridantriebsstränge sind unterschiedliche Konzepte bekannt.Different concepts are known in the field of hybrid powertrains.
Bei Doppelkupplungsgetrieben ist es bekannt, eine elektrische Maschine an eines der zwei Teilgetriebe anzubinden, und zwar in Leistungsflussrichtung gesehen hinter den eingangsseitigen Reibkupplungen (Doppelkupplung). Bei dieser Ausführungsform ist ein rein elektrischer Fahrbetrieb über eines der Teilgetriebe möglich. Ferner kann Leistung über das der elektrischen Maschine zugeordnete Teilgetriebe von der ersten Antriebseinheit (Verbrennungsmotor) übertragen werden, derart, dass die Leistung von erster und zweiter Antriebseinheit sich auf dem gleichen Leistungsübertragungspfad überlagern lassen.In the case of double clutch transmissions, it is known to connect an electrical machine to one of the two subtransmissions, namely behind the input-side friction clutches (double clutch) as seen in the power flow direction. In this embodiment, a purely electric driving operation via one of the sub-transmissions is possible. Furthermore, power can be transmitted from the first drive unit (internal combustion engine) via the sub-transmission assigned to the electric machine, in such a way that the power from the first and second drive units can be superimposed on the same power transmission path.
Bei derartigen Getrieben ist jedoch auch eine sog. Torque-Split-Betriebsweise möglich. Hierbei wird Leistung über unterschiedliche Leistungsübertragungspfade auf den Getriebeausgang geführt. Beispielsweise wird elektrische Leistung über das eine Teilgetriebe auf den Getriebeausgang geführt, und verbrennungsmotorische Leistung wird über das andere Teilgetriebe auf den Getriebeausgang geführt, so dass sich die Antriebsleistungen am Getriebeausgang aufsummieren. Dies ermöglicht eine Vielzahl weiterer Betriebsarten, einschließlich einer Zugkraftunterstützung über die elektrische Maschine bei Gangwechseln, einen Segel-Modus, bei dem der elektrische Motor abgeschaltet wird und die elektrische Maschine bedarfsweise Leistung zuführt, um eine bestimmte Geschwindigkeit zu halten, etc. Generell können Hybridantriebsstränge so ausgelegt sein, dass Antriebsleistung überwiegend von der ersten Antriebseinheit in Form eines Verbrennungsmotors bereitgestellt wird, wobei die zweite Antriebseinheit in Form einer elektrischen Maschine lediglich zur Unterstützung verwendet wird, oder für sehr kurze Fahrstrecken. Andere Hybridantriebsstränge sind so ausgebildet, dass die Leistung von Verbrennungsmotor und elektrischer Maschine in der gleichen Größenordnung liegen kann. Dies hängt maßgeblich auch davon ab, wie groß die Batterie ist, die in den Antriebsstrang integriert wird.In the case of such transmissions, however, what is known as a torque-split mode of operation is also possible. Here, power is fed to the transmission output via different power transmission paths. For example, electrical power is fed to the transmission output via one sub-transmission, and power from the internal combustion engine is fed to the transmission output via the other sub-transmission, so that the drive powers at the transmission output add up. This enables a multitude of other modes of operation, including traction support via the electric machine when changing gears, a sailing mode in which the electric motor is switched off and the electric machine supplies power as required in order to maintain a certain speed, etc. In general, hybrid drive trains can do this be designed so that drive power is predominantly provided by the first drive unit in the form of an internal combustion engine, the second drive unit in the form of an electric machine being used only for support, or for very short journeys. Other hybrid drive trains are designed so that the performance of the internal combustion engine and the electric machine can be of the same order of magnitude. This also largely depends on the size of the battery that is integrated into the drive train.
Generell benötigt ein Fahrbetrieb mit einem Verbrennungsmotor eine relativ große Anzahl von Gangstufen (Übersetzungsverhältnissen), um den Verbrennungsmotor jeweils in einem günstigen Drehzahlband nutzen zu können. Eine elektrische Maschine benötigt in der Regel deutlich weniger Gangstufen.In general, driving with an internal combustion engine requires a relatively large number of gear steps (gear ratios) in order to be able to use the internal combustion engine in a favorable speed range. An electric machine usually requires significantly fewer gear steps.
Manche Hybridantriebsstränge besitzen für den Antrieb mittels Verbrennungsmotor keine eigene Rückwärtsgangstufe, um Gewicht einzusparen. Ein Rückwärtsfahren ist bei derartigen Antriebssträngen ausschließlich mittels des elektrischen Motors möglich, dessen Drehrichtung dann zum Rückwärtsfahren umgekehrt wird.Some hybrid drivetrains do not have their own reverse gear for driving with an internal combustion engine in order to save weight. With such drive trains, reversing is only possible by means of the electric motor, the direction of rotation of which is then reversed for reversing.
Generell besteht ein Bedarf nach Hybridantriebssträngen, die einfach und kostengünstig realisierbar sind, und bei denen ein möglichst großer Funktionalitätsumfang gewährleistet ist.In general, there is a need for hybrid drive trains that can be implemented simply and inexpensively and that guarantee the greatest possible scope of functionality.

Ein reiner Fahrbetrieb mit der ersten Antriebseinheit ist zum einen über zwei Übersetzungen des ersten Teilgetriebes möglich, und, bei geschlossener Brückenkupplung, ferner über die zwei Übersetzungen des zweiten Teilgetriebes. Demzufolge kann ein Vorwärtsfahrbetrieb mit der ersten Antriebseinheit über wenigstens vier Übersetzungen eingerichtet werden, die vorzugsweise nach der Art von Gangstufen 1, 2, 3, 4 zueinander abgestimmt sind.Pure driving operation with the first drive unit is possible on the one hand via two gear ratios of the first sub-transmission and, with the bridge clutch closed, also via the two gear ratios of the second sub-gear. As a result, can forward drive operation can be set up with the first drive unit via at least four gear ratios, which are preferably matched to one another according to the type of
In dem ersten Teilgetriebe ist ein Radsatz vorhanden, der ein Rückwärtsfahrbetrieb ermöglicht, so dass, ein Rückwärtsfahren auch rein verbrennungsmotorisch möglich ist.In the first sub-transmission there is a gear set that enables reverse travel, so that reverse travel is also possible purely using an internal combustion engine.
Es ist Aufgabe der Erfindung, ein Hybridgetriebe zu schaffen, das einen Rückwärtsgang für elektrischen als auch verbrennungsmotorischen Betrieb aufweist, der zugleich als sehr hoch übersetzter Gang für den elektrischen Antrieb dient.It is the object of the invention to create a hybrid transmission which has a reverse gear for both electric and internal combustion engine operation, which at the same time serves as a very high-ratio gear for the electric drive.
Die Aufgabe wird gelöst mit einem Hybridantriebsstrang für ein Kraftfahrzeug, mit einer Eingangswellenanordnung, die eine erste Eingangswelle und eine zweite Eingangswelle aufweist, wobei die erste Eingangswelle mit einer ersten Reibkupplung verbunden ist, wobei die zweite Eingangswelle mit einer zweiten Reibkupplung verbunden ist und wobei die zweite Eingangswelle als Hohlwelle um die erste Eingangswelle herum angeordnet ist,
- - einem zweiten Teilgetriebe, das der ersten Eingangswelle zugeordnet ist, und einem ersten Teilgetriebe, das der zweiten Eingangswelle zugeordnet ist,
- - einer ersten Ausgangswelle und einer zweiten Ausgangswelle, wobei an den Ausgangswellen je ein Abtriebszahnrad vorgesehen ist,
- - einer Mehrzahl der Einrichtung von Gangstufen dienenden Radsätzen, die jeweils die Eingangswellenanordnung mit der ersten Ausgangswelle und/oder mit der zweiten Ausgangswelle verbinden, und
- - einer elektrischen Maschine, die an eines der Teilgetriebe angekoppelt ist, wobei auf der zweiten Ausgangswelle eine hochübersetzte Gangstufe angeordnet ist, die sowohl für den Rückwärtsgang als auch für einen rein elektrischen Kriechgang nutzbar ist.
- - A second sub-transmission, which is assigned to the first input shaft, and a first sub-transmission, which is assigned to the second input shaft,
- - A first output shaft and a second output shaft, a driven gear being provided on each of the output shafts,
- a plurality of gear sets serving to set up gear stages, each of which connects the input shaft arrangement to the first output shaft and / or to the second output shaft, and
- - An electrical machine which is coupled to one of the sub-transmissions, with a high-ratio gear stage being arranged on the second output shaft, which can be used both for reverse gear and for a purely electric crawler gear.
Dadurch ist auf einfache Weise eine Mehrfachnutzung einer Gangstufe umgesetzt, so dass die Gangstufe mit hoher Übersetzung für das elektrifizierte Teilgetriebe für Sondermanöver als Kriechgang eingesetzt wird. Er stellt einen zusätzlichen Fahrgang im elektrifizierten Teilgetriebe dar. Gleichzeitig kann die Gangstufe für den Verbrennungsmotor als auch für die elektrische Maschine als Rückwärtsgang verwendet werden.As a result, multiple use of a gear stage is implemented in a simple manner, so that the gear stage with a high gear ratio for the electrified sub-transmission is used as a creep gear for special maneuvers. It represents an additional gear in the electrified sub-transmission. At the same time, the gear stage for the internal combustion engine and for the electric machine can be used as a reverse gear.
Eine Brückenkupplung verbindet die beiden Ausgangswellen über Synchroneinheiten, was platzsparend umsetzbar ist.A bridge coupling connects the two output shafts via synchronous units, which can be implemented to save space.
Es ist von Vorteil, dass die Brückenkupplung eine Synchroneinheit auf der zweiten Abtriebswelle benutzt.It is advantageous that the bridge coupling uses a synchronizing unit on the second output shaft.
Dazu ist pro Teilgetriebe noch je eine weitere Synchroneinheit verbaut.For this purpose, an additional synchronizer unit is installed for each partial transmission.
Die Anordnung ist entweder so, dass das erste Teilgetriebe gerade Gangstufen enthält und näher an der der Doppelkupplung angebracht ist als das zweite Teilgetriebe (TG2), das die ungeraden Gangstufen enthält oder umgekehrt.The arrangement is either such that the first sub-transmission contains even gears and is attached closer to that of the double clutch than the second sub-transmission (TG2), which contains the uneven gears, or vice versa.
Die elektrische Maschine ist am ersten oder zweiten Teilgetriebe angebunden.The electrical machine is connected to the first or second partial transmission.
Das erfindungsgemäße Verfahren zum Betrieb eines Hybridantriebsstrangs verwendet das Getriebedesign, wobei über die hochübersetzte Gangstufe eine Rückwärtsfahrt mit dem Verbrennungsmotor eingerichtet wird, als auch einen Rückwärts- als auch Vorwärtsgangstufe für die elektrische Maschine.The method according to the invention for operating a hybrid drive train uses the transmission design, with reverse travel with the internal combustion engine being set up via the high-ratio gear stage, as well as a reverse and forward gear stage for the electric machine.
