Description
Die Erfindung betrifft eine Getriebeeinheit (auch als (dediziertes) Hybridgetriebe bezeichnet) für ein hybrides Kraftfahrzeug, mit einem Planetengetriebe, wobei das Planetengetriebe mit einem ersten Planetenradsatz und einem zweiten Planetenradsatz ausgestattet ist, und wobei eine zur Koppelung mit einer Verbrennungskraftmaschine vorbereitete Eingangswelle des Planetengetriebes mit einem, den ersten Planetenradsatz lagernden, ersten Planetenträger und/oder mit einem, mit dem ersten Planetenradsatz in Zahneingriff stehenden, ersten Sonnenrad koppelbar ist, mit einer elektrischen Maschine sowie nicht mehr als vier, jeweils eine Bremse, eine Kupplung oder einen Freilauf bildender, zum Schalten verschiedener Getriebeübersetzungen wirkend eingesetzter Schalteinrichtungen. Des Weiteren betrifft die Erfindung ein Kraftfahrzeug mit dieser Getriebeeinheit.The invention relates to a gear unit (also referred to as a (dedicated) hybrid gear) for a hybrid motor vehicle, with a planetary gear, the planetary gear being equipped with a first planetary gear set and a second planetary gear set, and an input shaft of the planetary gear prepared for coupling to an internal combustion engine one, the first planetary gear set superimposed, first planet carrier and / or with a, with the first planetary gear set in meshing engagement, first sun gear can be coupled to an electrical machine and no more than four, each forming a brake, a clutch or a freewheel, for Shifting of different gear ratios of effective shifting devices. The invention also relates to a motor vehicle with this transmission unit.
Aus dem Stand der Technik sind bereits gattungsgemäße Ausführungen von Hybridgetrieben bekannt. Beispielsweise offenbart die
Als Nachteil dieser aus dem Stand der Technik bekannten Getriebeeinheiten ist der relativ komplexe Aufbau heranzuführen. Insbesondere wird für die geforderte Fähigkeit, die Verbrennungskraftmaschine über die elektrische Maschine zu starten, ein relativ aufwändiger Aufbau eingesetzt.A disadvantage of these gear units known from the prior art is the relatively complex structure. In particular, a relatively complex structure is used for the required ability to start the internal combustion engine via the electrical machine.
Es ist daher Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik bekannten Nachteile zu beheben und eine Getriebeeinheit zur Verfügung zu stellen, die einen einfachen Aufbau aufweist und eine variable Ansteuerung der Betriebsmodi des Kraftfahrzeuges ermöglicht.It is therefore the object of the present invention to eliminate the disadvantages known from the prior art and to provide a transmission unit which has a simple structure and enables variable control of the operating modes of the motor vehicle.
Dies wird erfindungsgemäß dadurch gelöst, dass eine Rotorwelle der elektrischen Maschine mit einem, mit dem zweiten Planetenradsatz in Zahneingriff stehenden, zweiten Sonnenrad permanent drehfest verbunden ist.This is achieved according to the invention in that a rotor shaft of the electrical machine is permanently connected in a rotationally fixed manner to a second sun gear which is in meshing engagement with the second planetary gear set.
Durch diese Anbindung der elektrischen Maschine wird die Anzahl notwendiger Schalteinrichtungen reduziert. Dadurch wird eine Ansteuerbarkeit der entsprechenden Betriebsmodi relativ einfach.This connection to the electrical machine reduces the number of switching devices required. This makes it relatively easy to control the corresponding operating modes.
Weitere vorteilhafte Ausführungen sind mit den Unteransprüchen beansprucht und nachfolgend näher erläutert.Further advantageous designs are claimed with the subclaims and explained in more detail below.
In diesem Zusammenhang ist es demnach auch von Vorteil, wenn die Rotorwelle direkt mit dem zweiten Sonnenrad verbunden ist (sowie koaxial zu dem zweiten Sonnenrad angeordnet ist). Dadurch wird der Aufbau weiter vereinfacht.In this context, it is therefore also advantageous if the rotor shaft is connected directly to the second sun gear (and is arranged coaxially to the second sun gear). This further simplifies the structure.
Des Weiteren ist es vorteilhaft, wenn eine erste Schalteinrichtung und/oder eine zweite Schalteinrichtung als Kupplung ausgebildet sind/ist.Furthermore, it is advantageous if a first switching device and / or a second switching device are / is designed as a clutch.
Diesbezüglich hat es sich für eine einfache Ansteuerbarkeit als zweckdienlich herausgestellt, wenn die erste Schalteinrichtung als eine Kupplung, die zwischen der Eingangswelle und dem ersten Sonnenrad wirkend eingesetzt ist, ausgebildet ist, sodass in der aktivierten Stellung der ersten Schalteinrichtung die Eingangswelle mit dem ersten Sonnenrad rotatorisch verbunden ist und in der deaktivierten Stellung der ersten Schalteinrichtung die Eingangswelle von dem ersten Sonnenrad entkoppelt ist.In this regard, it has proven to be useful for simple controllability if the first switching device is designed as a clutch that is used between the input shaft and the first sun gear, so that in the activated position of the first switching device, the input shaft rotates with the first sun gear is connected and in the deactivated position of the first switching device, the input shaft is decoupled from the first sun gear.
Weiterhin ist es zweckmäßig, wenn die zweite Schalteinrichtung als eine Kupplung, die zwischen der Eingangswelle und dem ersten Planetenträger wirkend eingesetzt ist, ausgebildet ist, sodass in der aktivierten Stellung der zweiten Schalteinrichtung die Eingangswelle mit dem ersten Planetenträger rotatorisch verbunden ist und in der deaktivierten Stellung der zweiten Schalteinrichtung die Eingangswelle von dem ersten Planetenträger entkoppelt ist.Furthermore, it is expedient if the second shifting device is designed as a clutch which is inserted between the input shaft and the first planetary carrier, so that in the activated position of the second shifting device the input shaft is rotationally connected to the first planetary carrier and in the deactivated position of the second switching device, the input shaft is decoupled from the first planet carrier.
Alternativ zu der Ausbildung der zweiten Schalteinrichtung als Kupplung ist es auch zweckmäßig, diese als einen Freilauf umzusetzen, der zwischen der Eingangswelle und dem ersten Planetenträger wirkend eingesetzt ist, sodass in einem gesperrten Zustand der zweiten Schalteinrichtung, bei einer relativen Verdrehung des ersten Planetenträgers zu der Eingangswelle in einer ersten Drehrichtung, die Eingangswelle mit dem ersten Planetenträger rotatorisch verbunden ist und in einem entsperrten Zustand der zweiten Schalteinrichtung, bei einer relativen Verdrehung des ersten Planetenträgers zu der Eingangswelle in einer der ersten Drehrichtung entgegengesetzten zweiten Drehrichtung, der erste Planetenträger frei zu der Eingangswelle verdrehbar ist.As an alternative to the design of the second switching device as a clutch, it is also expedient to implement this as a freewheel, which is used between the input shaft and the first planet carrier so that in a locked state of the second switching device, with a relative rotation of the first planet carrier to the Input shaft in a first direction of rotation, the input shaft is rotationally connected to the first planet carrier and in an unlocked state of the second switching device, with a relative rotation of the first planet carrier to the input shaft in a second direction of rotation opposite to the first direction of rotation, the first planet carrier is free to the input shaft is rotatable.
Für eine weitere Optimierung und zur Ansteuerung der entsprechenden Betriebsmodi ist es auch von Vorteil, wenn eine dritte Schalteinrichtung und/oder eine vierte Schalteinrichtung als Bremse ausgebildet sind/ist.For further optimization and for controlling the corresponding operating modes, it is also advantageous if a third switching device and / or a fourth switching device are / is designed as a brake.
Dabei ist es besonders vorteilhaft, wenn die dritte Schalteinrichtung als eine auf das erste Sonnenrad einwirkende Bremse ausgebildet ist, sodass in der aktivierten Stellung der dritten Schalteinrichtung eine Rotation des ersten Sonnenrades blockiert ist und in der deaktivierten Stellung der dritten Schalteinrichtung eine freie Rotation des ersten Sonnenrades ermöglicht ist.It is particularly advantageous if the third switching device is designed as a brake acting on the first sun gear so that rotation of the first sun gear is blocked in the activated position of the third switching device and free rotation of the first sun gear in the deactivated position of the third switching device is made possible.
In Bezug auf die vierte Schalteinrichtung ist es von Vorteil, wenn diese als eine auf den ersten Planetenträger einwirkende Bremse ausgebildet ist, sodass in der aktivierten Stellung der vierten Schalteinrichtung eine Rotation des ersten Planetenträgers blockiert ist und in der deaktivierten Stellung der vierten Schalteinrichtung eine freie Rotation des ersten Planetenträgers ermöglicht ist.With regard to the fourth switching device, it is advantageous if it is designed as a brake acting on the first planet carrier so that rotation of the first planet carrier is blocked in the activated position of the fourth switching device and free rotation is blocked in the deactivated position of the fourth switching device of the first planet carrier is made possible.
Auch ist es von Vorteil, wenn die Getriebeeinheit derart ausgebildet ist, dass durch sie in einem ersten Betriebsmodus bei Betrieb der Verbrennungskraftmaschine zwei Vorwärtsgänge zwischen der Eingangswelle und dem Ausgang schaltbar sind. Des Weiteren ist die Getriebeeinheit derart ausgebildet, dass durch sie in einem zweiten Betriebsmodus, bei Betrieb der Verbrennungskraftmaschine sowie gleichzeitig bei Generatorbetrieb der elektrischen Maschine, ebenfalls zwei Vorwärtsgänge zwischen der Eingangswelle und dem Ausgang schaltbar sind. Des Weiteren ist die Getriebeeinheit derart ausgebildet, dass zwei Gänge (sowohl als Vorwärtsgänge als auch als Rückwärtsgänge) in einem rein elektrischen Betrieb (bei abgekoppelter Verbrennungskraftmaschine) schaltbar sind. Weiter bevorzugt ist die Getriebeeinheit derart ausgebildet, dass ein Laden in einem Stillstand des Kraftfahrzeuges ermöglicht ist. Auch ist es möglich, die Getriebeeinheit derart auszubilden, dass ein Boosten oder ein Rekuperieren in allen Gängen des rein verbrennungskraftmaschinenseitigen Antriebs ermöglicht ist. Auch ist die Getriebeeinheit derart ausgebildet, dass ein Rückwärtsgang bei Betrieb der Verbrennungskraftmaschine umsetzbar ist.It is also advantageous if the transmission unit is designed in such a way that it can be used to shift two forward gears between the input shaft and the output in a first operating mode when the internal combustion engine is in operation. Furthermore, the transmission unit is designed in such a way that it can also be used to switch two forward gears between the input shaft and the output in a second operating mode, when the internal combustion engine is in operation and at the same time when the electric machine is in generator operation. Furthermore, the transmission unit is designed in such a way that two gears (both as forward gears and as reverse gears) can be shifted in a purely electric mode (when the internal combustion engine is decoupled). The transmission unit is further preferably designed in such a way that charging is possible when the motor vehicle is at a standstill. It is also possible to design the transmission unit in such a way that boosting or recuperation is possible in all gears of the drive purely on the internal combustion engine side. The transmission unit is also designed in such a way that a reverse gear can be implemented when the internal combustion engine is in operation.
Die elektrische Maschine ist koaxial oder achsparallel (auch vorzugsweise mit Kette oder Stirnrad) zu einer Drehachse der Eingangswelle angeordnet.The electrical machine is arranged coaxially or axially parallel (also preferably with a chain or spur gear) to an axis of rotation of the input shaft.
Des Weiteren betrifft die Erfindung ein Kraftfahrzeug mit einer Verbrennungskraftmaschine und einer mit ihrem Eingang an eine Ausgangswelle der Verbrennungskraftmaschine angeschlossenen erfindungsgemäßen Getriebeeinheit nach zumindest einer der zuvor beschriebenen Ausführungen.The invention also relates to a motor vehicle with an internal combustion engine and a transmission unit according to the invention connected with its input to an output shaft of the internal combustion engine according to at least one of the embodiments described above.
In anderen Worten ausgedrückt, wird erfindungsgemäß ein dediziertes Hybridgetriebe mit Planetenradsätzen, zwei Gängen für die Verbrennungskraftmaschine, zwei EVT-Gängen und zwei Gängen für die elektrische Maschine umgesetzt. Das dedizierte Hybridgetriebe weist zwei Planetenradsätze, eine elektrische Maschine und nicht mehr als vier Schalteinrichtungen / Schaltelemente sowie keine separate Trennkupplung zum Koppeln / Entkoppeln der Verbrennungskraftmaschine an / von einem Antriebsstrang zum rein elektrischen Antrieb auf. Die elektrische Maschine ist (direkt) mit einem Sonnenrad eines Planetenradsatzes verbunden.In other words, according to the invention, a dedicated hybrid transmission with planetary gear sets, two gears for the internal combustion engine, two EVT gears and two gears for the electric machine is implemented. The dedicated hybrid transmission has two planetary gear sets, an electric machine and no more than four shifting devices / shifting elements as well as no separate disconnecting clutch for coupling / decoupling the internal combustion engine to / from a drive train for the purely electric drive. The electric machine is (directly) connected to a sun gear of a planetary gear set.
