Die Erfindung bezieht sich auf eine Hybridantriebsanordnung für ein Kraftfahrzeug, deren Elemente wenigstens abschnittsweise in einem Gehäuse enthalten sind.The invention relates to a hybrid drive assembly for a motor vehicle whose elements are at least partially contained in a housing.
Stand der TechnikState of the art
Hybridantriebsanordnungen in Form leistungsverzweigter Getriebe sind dem Fachmann in vielfacher Ausgestaltung bekannt. Derartige Antriebsanordnungen, die zwischen einer mit der Antriebswelle verbundenen Verbrennungskraftmaschine und einem mit der Abtriebswelle verbundenen Abtrieb des Kraftfahrzeugs vorgesehen sind, umfassen eine erste elektrische Maschine, die üblicherweise als Innenläufer, d. h. mit innenliegendem Rotor und außenliegendem, gehäusefestem Stator, ausgebildet und sowohl im motorischen als auch im generatorischen Betrieb betreibbar ist, sowie eine zweite elektrische Maschine, die üblicherweise ebenfalls als Innenläufer ausgebildet und sowohl im motorischen als auch im generatorischen Betrieb betreibbar ist. Allgemein kann von Motor/Generator-Einheiten gesprochen werden. Der Einfachheit der Erläuterung halber wird im Rahmen der vorliegenden Beschreibung jedoch vorwiegend von elektrischen Maschinen gesprochen, ohne dass die vorliegende Erfindung auf solche beschränkt wäre. Die elektrischen Maschinen der bekannten Antriebsvorrichtungen sind über eine Leistungselektronik sowohl untereinander als auch mit einem elektrischen Energiespeicher, insbesondere einem Akkumulator verbunden. Weiter umfassen die bekannten Hybridantriebsanordnungen zwei Planetengetriebe, jeweils mit Sonnenrad, Hohlrad und einem mit dem Hohlrad und dem Sonnenrad kämmenden, drehbar auf einem Steg montierten Satz von Planetenrädern. Weiter ist es bekannt, mehrere Schaltelemente vorzusehen, mit denen einzelne der vorgenannten Elemente untereinander oder mit dem Gehäuse gekoppelt sind. Unter „gekoppelt” sei im Rahmen der vorliegenden Beschreibung eine zwischen einem momentenübertragenden und einem nicht-momentenübertragenden Zustand schaltbare Verbindung verstanden. Im Gegensatz dazu wird der Ausdruck „fest verbunden” im vorliegenden Zusammenhang für eine nicht schaltbare, momentenübertragende Verbindung verwendet.Hybrid drive arrangements in the form of power-split transmissions are known to the person skilled in many designs. Such drive arrangements, which are provided between an internal combustion engine connected to the drive shaft and an output of the motor vehicle connected to the output shaft, comprise a first electric machine, which is usually designed as an internal rotor, i. H. with internal rotor and external, stationary stator, trained and operable in both motor and generator operation, and a second electric machine, which is usually also designed as an internal rotor and is operable in both motor and generator operation. In general, we can speak of motor / generator units. However, in the context of the present description, for the sake of simplicity of explanation, electrical machines are predominantly discussed, without the present invention being restricted to such. The electrical machines of the known drive devices are connected via power electronics both with each other and with an electrical energy storage, in particular a battery. Further, the known hybrid drive assemblies include two planetary gears, each with sun gear, ring gear and a meshing with the ring gear and the sun gear, rotatably mounted on a bridge set of planetary gears. Further, it is known to provide a plurality of switching elements with which individual of the aforementioned elements are coupled to each other or to the housing. In the context of the present description, "coupled" is understood to be a connection which can be switched between a torque-transmitting state and a non-torque-transmitting state. In contrast, the term "firmly connected" in the present context is used for a non-switchable, torque-transmitting connection.
Je nach Topologie der Hybridantriebsanordnung sind unterschiedliche Anzahlen und Arten von Betriebsmodi realisierbar. Insbesondere lassen sich feste Drehzahlübersetzungen (Gänge) zwischen An- und Abtriebswelle, durch Verstellung von Drehzahl und/oder Moment einer oder beider elektrischer Maschinen kontinuierlich verstellbare Drehzahlübersetzungen im leistungsverzweigten Betriebsmodi sowie rein elektrische Betriebmodi realisieren.Depending on the topology of the hybrid drive arrangement different numbers and types of operating modes can be realized. In particular, fixed speed ratios (gears) between input and output shaft, by adjusting the speed and / or torque of one or both electrical machines continuously variable speed ratios in the power-split operating modes and purely electrical operating modes can be realized.

Die erste und/oder die zweite elektrische Maschine ist/sind vorzugsweise koaxial zur Antriebswelle angeordnet. Hierdurch wird eine besonders kompakte Bauform realisiert. Diese Topologie lässt sich so realisieren, dass die Abtriebswelle die Antriebswelle koaxial umgreift.The first and / or the second electric machine is / are preferably arranged coaxially to the drive shaft. As a result, a particularly compact design is realized. This topology can be realized so that the output shaft coaxially surrounds the drive shaft.

Alternatively, the output shaft may be connected to a drive train section oriented perpendicular to the drive shaft. In particular, it can be arranged between the first and the second electrical machine. These second design variants are particularly suitable for transverse installation, in particular the front-transverse installation in the motor vehicle.
Bezüglich der Verschaltung der einzelnen Elemente sind im Rahmen der Erfindung zwei Varianten denkbar. Bei einer ersten Verschaltungsvariante ist vorgesehen, dass der Steg des ersten Planetengetriebes mit dem Steg des zweiten Planetengetriebes fest verbunden ist. Diese Verschaltungsvariante lässt sich für beide oben erwähnten Bauformvarianten, d. h. diejenige für den Längs- und diejenige für den Quereinbau realisieren. Alternativ dazu kann bei einer zweiten Verschaltungsvariante vorgesehen sein, dass die Antriebswelle mittels einer zweiten Kupplung mit dem Steg des ersten Planetengetriebes gekoppelt ist. Diese Verschaltungsvariante ist nur im Zusammenhang mit der zweiten Bauformvariante d. h. denjenigen für den Quereinbau sinnvoll. Die Wirkungsweisen der beiden vorgenannten Verschaltungsvarianten sollen nachfolgend im Einzelnen erläutert werden. Dabei kann die Beschreibung der ersten Verschaltungsvariante unverändert auf die zweite Verschaltungsvariante in deren geschlossenem Zustand der zweiten Kupplung übertragen werden.With regard to the interconnection of the individual elements, two variants are conceivable within the scope of the invention. In a first Verschaltungsvariante is provided that the web of the first planetary gear is fixedly connected to the web of the second planetary gear. This wiring variant can be used for both types of construction mentioned above, d. H. realize the one for the longitudinal and the one for the transverse installation. Alternatively, it may be provided in a second Verschaltungsvariante that the drive shaft is coupled by means of a second clutch with the web of the first planetary gear. This wiring variant is only in connection with the second design variant d. H. those for cross installation makes sense. The modes of action of the two aforementioned Verschaltungsvarianten will be explained in detail below. The description of the first Verschaltungsvariante can be transferred unchanged to the second Verschaltungsvariante in its closed state of the second clutch.
Die erfindungsgemäße Hybridantriebsanordnung gemäß der ersten Verschaltungsvariante bietet zwei leistungsverzweigte Betriebsmodi, einen festen Gang im Overdrive-Bereich sowie einen rein elektrischen Betriebsmodus.The hybrid drive arrangement according to the invention according to the first interconnection variant offers two power-split operating modes, a fixed gear in the overdrive area and a purely electrical operating mode.
Im ersten leistungsverzweigten Betriebsmodus ist die erste Kupplung geschlossen, während die erste und die zweite Bremse geöffnet sind. Dieser Betriebsmodus kann vom Anfahren mit hoher Übersetzung bis in den nahen Overdrive-Bereich verwendet werden und stellt dort bei Hybridfahrt eine kontinuierliche Getriebeverstellung zur Verfügung. Moment der Verbrennungskraftmaschine wird über die Antriebswelle auf den Steg des ersten Planetengetriebes geleitet. Auch der Steg des zweiten Planetengetriebes, der mit dem Steg des ersten Planetengetriebes fest verbunden ist, läuft mit gleicher Drehzahl um. Aufgrund der offenen ersten Bremse, mit der das Sonnenrad des zweiten Planetengetriebes mit dem Gehäuse gekoppelt ist, nimmt der zweite Planetensatz in diesem Zustand jedoch keine Leistung auf. Moment und Drehzahl der Antriebswelle werden in dem ersten Planetensatz übersetzt und über dessen Hohlrad an den Abtrieb geleitet. Dabei arbeitet die erste elektrische Maschine, deren Rotor mit dem Sonnenrad des ersten Planetengetriebes fest verbunden ist, generatorisch. Ihre Drehzahl bestimmt die effektive Übersetzung des ersten Planetengetriebes. Insbesondere wird zur Verringerung der Übersetzung zwischen Antriebswelle und Abtriebswelle, d. h. wenn das Kraftfahrzeug Fahrt aufnimmt, wobei die Drehzahl der Antriebswelle bevorzugt im Bereich des optimalen Wirkungsgrades der Verbrennungskraftmaschine gehalten wird, die Drehzahl der ersten elektrischen Maschine reduziert. In diesem ersten leistungsverzweigten Betriebsmodus arbeitet die zweite elektrische Maschine, die über die geschlossene erste Kupplung mit dem Abtrieb verbunden ist, motorisch und kann dabei die bekannten Hybridfunktionen wie z. B. Boosten, durchführen. Der erste leistungsverzweigte Betriebsmodus erstreckt sich bis in die Nähe bzw. bis zum Stillstandspunkt der ersten elektrischen Maschine. Ein Stillstand der ersten elektrischen Maschine liegt im Bereich des nahen Overdrives. Im gleichen Bereich liegt der Punkt, in dem sich die Rotationen des Steges des zweiten Planetengetriebes und dessen Hohlrades so überlagern, dass (auch) das Sonnenrad des zweiten Planetengetriebes zum Stillstand kommt. Dieser Punkt ist insbesondere dann erreicht, wenn die Drehzahlen von An- und Abtriebswelle zueinander in dem von der Standübersetzung des zweiten Planetengetriebes vorgegebenen Verhältnis stehen. Ob dieser Punkt vor, nach, oder gleichzeitig mit dem Stillstandspunkt des Sonnenrades des ersten Planetengetriebes erreicht werden kann, hängt von der speziellen Parametrierung der beiden Planetengetriebe ab. Der Fachmann kann diese Auslegung in Ansehung des konkreten Einsatzfalles vornehmen.In the first power-split mode of operation, the first clutch is closed while the first and second brakes are open. This mode of operation can be used from start up to high overdrive in the near overdrive range, providing continuous transmission tuning during hybrid drive. Moment of the internal combustion engine is passed via the drive shaft to the web of the first planetary gear. Also, the web of the second planetary gear, which is fixedly connected to the web of the first planetary gear, runs at the same speed. However, due to the open first brake with which the sun gear of the second planetary gear is coupled to the housing, the second planetary gear set does not absorb power in this state. The torque and speed of the drive shaft are translated in the first planetary gear set and passed through the ring gear to the output. In this case, the first electric machine, whose rotor is fixedly connected to the sun gear of the first planetary gear, operates as a generator. Their speed determines the effective ratio of the first planetary gear. In particular, to reduce the ratio between the drive shaft and the output shaft, d. H. When the motor vehicle starts to move, wherein the rotational speed of the drive shaft is preferably kept in the range of the optimum efficiency of the internal combustion engine, the speed of the first electric machine is reduced. In this first power-split operating mode, the second electric machine, which is connected via the closed first clutch to the output, works by motor and can thereby the known hybrid functions such. B. Boost perform. The first power-split mode of operation extends into the vicinity or to the standstill point of the first electric machine. A stoppage of the first electric machine is in the range of the near overdrive. In the same area is the point in which overlap the rotations of the web of the second planetary gear and the ring gear so that (also) the sun gear of the second planetary gear comes to a standstill. This point is achieved in particular when the rotational speeds of the input and output shafts to each other are in the ratio specified by the state ratio of the second planetary gear. Whether this point before, after, or can be achieved simultaneously with the standstill point of the sun gear of the first planetary gear depends on the specific parameterization of the two planetary gear. The expert can make this interpretation in view of the specific application.
Im Stillstandspunkt des Sonnenrades des zweiten Planetengetriebes existiert keine Relativbewegung zwischen den Elementen, z. B. Lamellen der ersten Bremse. Die erste Bremse kann daher in diesem Zustand ohne Reibungsverluste geschlossen werden. Der dadurch realisierte Betriebsmodus, der sich bei geschlossener erster Bremse und geschlossener erster Kupplung einstellt, entspricht einem festen Gang im nahen Overdrive-Bereich, d. h. zum Beispiel einem sechsten Gang. In diesem Betriebsmodus wirkt das zweite Planetengetriebe aufgrund seines festgehaltenen Sonnenrades als reine Übersetzungsstufe, über die das Moment der Verbrennungskraftmaschine übersetzt und auf den Abtrieb geleitet wird. Dabei kann die zweite elektrische Maschine, die über die erste Kupplung ebenfalls mit dem Abtrieb verbunden ist, in parallel-hybrider Weise Moment beisteuern. Die erste elektrische Maschine wirkt dabei nach wie vor generatorisch. Die Stärke des generatorischen Bremsmomentes kann dabei fahrsituationsgemäß variiert werden. Insbesondere kann die Belastung der ersten Bremse hierdurch bis zur völligen Ent- oder Belastung gesteuert werden.At the standstill point of the sun gear of the second planetary gear exists no relative movement between the elements, eg. B. slats of the first brake. The first brake can therefore be closed in this state without friction losses. The thus realized operating mode, the Setting with the first brake closed and the first clutch closed, corresponds to a fixed gear in the near overdrive range, ie, for example, a sixth gear. In this mode of operation, the second planetary gear acts due to its retained sun gear as a pure translation stage, via which translates the moment of the internal combustion engine and directed to the output. In this case, the second electric machine, which is also connected to the output via the first clutch, contribute torque in a parallel-hybrid manner. The first electric machine still acts as a generator. The strength of the regenerative braking torque can be varied according to the driving situation. In particular, the load on the first brake can thereby be controlled until complete unloading or loading.
Öffnen der ersten Kupplung führt zu einem Übergang in den zweiten leistungsverzweigten Betriebsmodus. In diesem wirkt die zweite elektrische Maschine rein generatorisch. Das zweite Planetengetriebe wirkt aufgrund seines festgehaltenen Sonnenrades als reine Übersetzungsstufe. Das über den Steg des zweiten Planetengetriebes eingebrachte Moment der Verbrennungskraftmaschine treibt den Rotor der zweiten elektrischen Maschine an, ohne dass – wegen der geöffneten ersten Kupplung-Moment weiter zum Abtrieb geleitet würde. Vielmehr wird das Moment der Verbrennungskraftmaschine über das erste Planetengetriebe auf den Abtrieb geleitet, wobei die erste elektrische Maschine motorisch arbeitet und am Sonnenrad des ersten Planetengetriebes ein Moment abstützt.Opening the first clutch results in a transition to the second power split mode of operation. In this, the second electric machine acts purely as a generator. The second planetary gear acts due to its retained sun gear as a pure translation stage. The introduced via the web of the second planetary gear torque of the internal combustion engine drives the rotor of the second electric machine, without that - because of the opened first clutch torque would continue to be driven to the output. Rather, the moment of the internal combustion engine is passed through the first planetary gear to the output, wherein the first electric machine operates by motor and at the sun gear of the first planetary gear supports a moment.
Schließlich ist noch ein rein elektrischer Fahrbetrieb vorgesehen, bei dem die erste Kupplung geöffnet ist, während die erste und zweite Bremse geschlossen sind. Dies setzt Stillstand der Antriebswelle bzw. der Verbrennungskraftmaschine voraus, während die erste elektrische Maschine die alleinige Momentenquelle in diesem Zustand bildet. Die zweite elektrische Maschine ist in diesem Zustand ungenutzt. Insbesondere kann sie unbestromt bleiben, da sie aufgrund der geschlossen zweiten Bremse, welche ein auf die Antriebswelle rückwirkendes Moment gegen das Gehäuse abstützt, selbst nicht zu dessen Abstützung benötigt wird. Folglich können in der zweiten elektrischen Maschine in diesem Zustand keine elektrischen Verluste auftreten, was den Wirkungsgrad der Antriebsanordnung insgesamt erhöht.Finally, a purely electric driving operation is provided, in which the first clutch is opened, while the first and second brakes are closed. This requires standstill of the drive shaft or the internal combustion engine, while the first electric machine forms the sole moment source in this state. The second electric machine is unused in this state. In particular, it can remain de-energized, since it is not required to support it due to the closed second brake, which supports a torque acting on the drive shaft against the housing. Consequently, no electrical losses can occur in the second electric machine in this state, which increases the overall efficiency of the drive arrangement.
Bis hierher deckt sich die Funktionsweise der ersten Verschaltungsvariante mit derjenigen der zweiten Verschaltungsvariante bei geschlossener zweiter Kupplung. Die besondere Wirkung der zweiten Verschaltungsvariante kommt im zuletzt beschriebenen rein elektrischen Fahrbetreib zur Geltung. Durch Öffnen der zweiten Kupplung wird der Zwang zum Stillstand der Antriebswelle bzw. der Verbrennungskraftmaschine beim elektrischen Fahrbetrieb aufgehoben. Die Antriebswelle ist dabei vollständig von derjenigen Welle entkoppelt, an die bei der ersten Verschaltungsvariante die zweite Bremse angeschlossen ist. Nach wie vor bringt die erste elektrische Maschine das gesamte Moment zur Bewegung des Fahrzeugs im elektrischen Fahrbetrieb auf. Unabhängig hiervon kann die Verbrennungskraftmaschine jedoch benutzt werden, um über das zweite Planetengetriebe, welches aufgrund seines festgehaltenen Sonnenrades als reine Übersetzungsstufe fungiert, die zweite elektrische Maschine generatorisch zu betreiben. Man spricht hier von einer „Range Extender”-Funktion, die im Grunde einen strikt seriellen Hybridbetrieb entspricht.Up to this point, the mode of operation of the first interconnection variant coincides with that of the second interconnection variant with the second coupling closed. The special effect of the second Verschaltungsvariante comes in the last-described purely electric driving advantage. By opening the second clutch, the compulsion to stop the drive shaft or the internal combustion engine during electric driving is canceled. The drive shaft is completely decoupled from that shaft to which the second brake is connected in the first Verschaltungsvariante. As before, the first electric machine applies the entire moment to the movement of the vehicle in electric driving mode. Regardless of this, however, the internal combustion engine can be used to operate on the second planetary gear, which acts as a pure translation stage due to its retained sun gear, the second electric machine as a generator. This is called a "Range Extender" function, which basically corresponds to a strictly serial hybrid operation.
Bei einer Weiterbildung der Erfindung, die auf sämtliche vorgenannten Varianten anwendbar ist, ist vorgesehen, dass die Antriebswelle mittels einer dritten Kupplung mit dem Rotor der ersten elektrischen Maschine gekoppelt ist. Durch Schließen der dritten Kupplung bei geöffneter zweiter Bremse läuft das erst Planetengetriebe, dessen Sonnenrad und dessen Steg mit derselben Drehzahl betrieben werden, als Block um, sodass ein Direktgang mit einer Übersetzung zwischen Antriebswelle und Abtriebswelle von genau eins realisiert wird. Dabei muss wenigstens eine der beiden am zweiten Planetengetriebe angreifenden Schaltelemente, d. h. die erste Kupplung und/oder die erste Bremse geöffnet sein.In a development of the invention, which is applicable to all the aforementioned variants, it is provided that the drive shaft is coupled by means of a third clutch to the rotor of the first electric machine. By closing the third clutch when the second brake is open, the first planetary gear whose sun gear and the web are operated at the same speed runs as a block, so that a direct gear with a ratio between the drive shaft and output shaft of exactly one is realized. In this case, at least one of the two acting on the second planetary gear shift elements, d. H. the first clutch and / or the first brake to be open.
Es sei darauf hingewiesen, dass im Rahmen der hiesigen Beschreibung vor alter von elektrischen Maschinen als Motor/Generatoreihheiten gesprochen wird. Die Erfindung ist jedoch nicht auf diese beschränkt.It should be noted that in the context of the description here before the age of electrical machines is spoken as motor / generator hunts. However, the invention is not limited to these.
Vielmehr ist unter Motor/Generator-Einheit allgemein ein sowohl motorisch als auch generatorisch betreibarer Energiewandler zu verstehen. Außer elektrischen Maschinen könnten hier auch hydraulische/pneumatische Pumpen/Motoren Verwendung finden.Rather, the term "motor / generator unit" is generally understood to mean an energy converter which can be operated both as a motor and as a generator. Apart from electric machines, hydraulic / pneumatic pumps / motors could also be used here.
