Description

Die Erfindung betrifft ein Hybrid-Planetengetriebe, umfassend ein Planetengetriebe und eine Elektromaschine zur Bildung eines Drehmomentwandlers sowie eine Getriebeeingangswelle und eine Motorwelle eines Verbrennungsmotors. The invention relates to a hybrid planetary gear, comprising a planetary gear and an electric machine for forming a torque converter and a transmission input shaft and a motor shaft of an internal combustion engine.

Aus der US 2014/0031158 A1 ist ein hybrides Planetengetriebe bekannt, welches mit einer Elektromaschine zusammenwirkt. Dieses Hybrid-Planetengetriebe weist eine Getriebeeingangswelle und eine von einem Verbrennungsmotor angetriebene Motorwelle auf. Bei der Lastübertragung in dem hybriden Antriebsstrang treten hohe Energieverluste im Betrieb, insbesondere während der Anlaufphase, auf, da einige Bauelemente nicht immer benötigt werden.From the US 2014/0031158 A1 is a hybrid planetary gear known which interacts with an electric machine. This hybrid planetary gear has a transmission input shaft and a motor shaft driven by an engine. During load transfer in the hybrid drive train, high energy losses occur during operation, in particular during the startup phase, since some components are not always required.

Der Erfindung liegt die Aufgabe zugrunde, ein Hybrid-Planetengetriebe anzugeben, welches die Energieverluste im Betrieb des Hybrid-Planetengetriebes reduziert.The invention has for its object to provide a hybrid planetary gear, which reduces the energy losses during operation of the hybrid planetary gear.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass mindestens eine Überbrückungskupplung in dem Hybrid-Planetengetriebe zur Ausschaltung von mindestens einem Bauteil angeordnet ist. Mittels dieser Überbrückungskupplung lassen sich also nicht gebrauchte Bauteile ausschalten, was zu einer Reduzierung des Energiebedarfs des Hybrid-Planetengetriebes führt. According to the invention the object is achieved in that at least one lock-up clutch is arranged in the hybrid planetary gear for eliminating at least one component. By means of this lock-up clutch, therefore, unused components can be switched off, which leads to a reduction in the energy requirement of the hybrid planetary gear.

Vorteilhafterweise ist die Überbrückungskupplung als Wandlerüberbrückungskupplung und/oder als Elektromaschinenüberbrückungskupplung ausgebildet. Damit sind die Überbrückungskupplungen sehr flexibel in dem Hybrid-Planetengetriebe einsetzbar. Advantageously, the lockup clutch is designed as a lockup clutch and / or as an electric machine lockup clutch. Thus, the lock-up clutches are very flexible used in the hybrid planetary gear.

In einer Ausgestaltung ist die Wandlerüberbrückungskupplung vor oder hinter dem Drehmomentwandler angeordnet. In beiden Fällen führt die Platzierung dazu, dass der Drehmomentwandler zuverlässig abgeschaltet wird.In one embodiment, the lockup clutch is arranged in front of or behind the torque converter. In both cases, the placement results in the torque converter being reliably shut down.

In einer Ausgestaltung ist eine Dämpfer-Pendeleinheit vor und/oder nach dem Drehmomentwandler positioniert. Durch diese Dämpfer-Pendeleinheit, beispielsweise einem Fliehkraftpendel, wird die Dämpfung bzw. die Tilgung von Motorschwingungen im Antriebsstrang, welcher das Hybrid-Planetengetriebe enthält, reduziert.In one embodiment, a damper pendulum unit is positioned in front of and / or behind the torque converter. By this damper pendulum unit, such as a centrifugal pendulum, the damping or the eradication of engine vibrations in the drive train, which contains the hybrid planetary gear reduced.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Mehrere davon sollen anhand der in der Zeichnung dargestellten Figuren näher erläutert werden. The invention allows numerous embodiments. Several of these will be explained in more detail with reference to the figures shown in the drawing.

In 1 sind verschiedenen Ausführungen des Hybrid-Planetengetriebes dargestellt. Bei der in 1a dargestellten Ausführung wird eine Elektromaschine 1 durch einen Stator 2 und einen Rotor 3 gebildet, welche über ein Motorblech 4 mit einem Planeten-Getriebe 5 verbunden sind. Das Planeten-Getriebe 5 weist dabei eine Getriebeeingangswelle 6, welche an den Abtrieb führt, auf und ist mit einer Motorwelle 7, die von einem nicht weiter dargestellten Verbrennungsmotor angetrieben wird, verbunden. Das Planeten-Getriebe 5 und die Elektromaschine 1 bilden dabei einen Drehmomentwandler. 1b und 1c zeigen weitere Ausgestaltungen des in dem elektromechanischen Drehmomentwandler 1, 5 angeordneten Planeten-Getriebes 5, wobei getriebeeingangswelle 6 und Motorwelle 7 unterschiedliche Eingriffe am Planeten-Getriebe 5 aufweisen.In 1 are shown different versions of the hybrid planetary gear. At the in 1a illustrated embodiment is an electric machine 1 through a stator 2 and a rotor 3 formed, which has a motor plate 4 with a planetary gear 5 are connected. The planetary gear 5 has a transmission input shaft 6 , which leads to the output, and is with a motor shaft 7 , which is driven by an internal combustion engine, not shown, connected. The planetary gear 5 and the electric machine 1 form a torque converter. 1b and 1c show further embodiments of the in the electromechanical torque converter 1 . 5 arranged planetary gear 5 where transmission input shaft 6 and motor shaft 7 different interventions on the planetary gear 5 exhibit.

In 2a bis c ist die Übersetzung des Planeten-Getriebes 5 geändert, indem eine Stufenverzahnung 8 eingeführt ist. Auch hierbei greifen bei den drei Varianten Motorwelle 7 und Getriebeeingangswelle 6 an unterschiedlichen Positionen des Planeten-Getriebes 5 an.In 2a to c is the translation of the planetary gear 5 changed by a stepped toothing 8th is introduced. Here, too, the three variants use a motor shaft 7 and transmission input shaft 6 at different positions of the planetary gear 5 at.

3 zeigt ein weiteres Ausführungsbeispiel des Hybrid-Planetengetriebes, bei welchem eine Wandlerüberbrückungskupplung 9 vor der Elektromaschine 1 angeordnet ist. Mittels dieser Wandlerüberbrückungskupplung 9 wird das als Zahnradgetriebe ausgebildeten Planeten-Getriebe 5 abgeschaltet. Bei dem in 4 gezeigten Ausführungsbeispiel des Hybrid-Planetengetriebes werden mittels einer Elektromaschinenüberbrückungskupplung 10 der Rotor 3 und der Stator 2 der Elektromaschine 1 gekoppelt, weshalb dieser sich nicht dreht. In 5 ist eine Kombination von Wandlerüberbrückungskupplung 9 und der Elektromaschinenübertragungskupplung 10 am Planeten-Getriebe 5 dargestellt, wo alternativ sowohl das Planeten-Getriebe 5 als auch die Elektromaschine 1 blockiert werden können. 3 shows a further embodiment of the hybrid planetary gear in which a lockup clutch 9 in front of the electric machine 1 is arranged. By means of this converter lockup clutch 9 is designed as a gear transmission planetary gear 5 off. At the in 4 shown embodiment of the hybrid planetary gear are by means of an electric machine lock-up clutch 10 the rotor 3 and the stator 2 the electric machine 1 coupled, which is why this does not turn. In 5 is a combination of torque converter lockup clutch 9 and the electric machine transmission clutch 10 at the planetary gearbox 5 shown where alternatively both the planetary gear 5 as well as the electric machine 1 can be blocked.

Für die Dämpfung der Motorschwingungen, welche im Antriebsstrang, in welchem die Hybrid-Planetengetriebe eingebaut sind, auftreten, ist eine Dämpfer-Pendeleinheit 11 vorgesehen. In 6 ist diese Dämpfer-Pendeleinheit 11 vor dem Drehmomentwandler 1, 5 angeordnet, während in 7 eine Ausführung dargestellt ist, bei welcher der die Dämpfer-Pendeleinheit 11 hinter dem Drehmomentwandler 11 positioniert ist. Die Ausführungsbeispiele 6 bzw. 7 umfassen im Weiteren die Anordnung der Wandlerüberbrückungskupplung 9 und der Elektromaschinenüberbrückungskupplung 10, wie sie in 5 dargestellt sind. For the damping of the engine vibrations, which occur in the drive train in which the hybrid planetary gear are installed, is a damper pendulum unit 11 intended. In 6 is this damper pendulum unit 11 in front of the torque converter 1 . 5 arranged while in 7 an embodiment is shown in which the damper pendulum unit 11 behind the torque converter 11 is positioned. The embodiments 6 respectively. 7 further include the arrangement of the lockup clutch 9 and the electric machine lockup clutch 10 as they are in 5 are shown.

In der Anlaufphase des nicht weiter dargestellten Verbrennungsmotors wird bei stillstehender Getriebeeingangswelle 6 zuerst der Rotor 3 der Elektromaschine 1 zur Bewegung gebracht, wobei die Elektromaschine 1 bevorzugt im Generatorstatus betrieben wird. In diesem Generatorstatus werden Energieverluste im Wandlerbetrieb teilweise zurückgeführt. Dabei auf den Rotor 3 wirkende elektromagnetische Kräfte, wie beispielsweise eine Stützkraft, bewirken eine allmähliche Beschleunigung der Getriebeeingangswelle 6. Nach dem Anlaufen kann der elektromechanische Drehmomentwandler 1, 5 mittels der Wandlerüberbrückungskupplung 9 überbrückt werden, wobei die Elektromaschine 1 entweder als Generator weiter läuft, bei dem ein Leistungsanteil zur Batterieladung genutzt wird, oder abgeschaltet werden kann, d.h. die Elektromaschine 1 läuft im Leerlauf. Ist dieser letztere Fall eingetreten, ist es effektiv mittels der Elektromaschinenüberbrückungskupplung 10, die Elektromaschine 1 zu überbrücken. In diesem Fall muss darauf geachtet werden, dass die Wandlerüberbrückungskupplung 9 offen ist, so dass keine Leistungsverluste durch den sich drehenden Rotor der Elektromaschine 1 entstehen.In the start-up phase of the internal combustion engine, not shown, is at a stationary transmission input shaft 6 first the rotor 3 the electric machine 1 moved, with the electric machine 1 is preferably operated in the generator status. In this generator status, energy losses during transformer operation are partially reduced. On the rotor 3 acting electromagnetic forces, such as a supporting force, cause a gradual acceleration of the transmission input shaft 6 , After starting up, the electromechanical torque converter 1 . 5 by means of the torque converter lockup clutch 9 be bridged, the electric machine 1 either continues to run as a generator in which a power component is used for battery charging, or can be switched off, ie the electric machine 1 is idling. If this latter case has occurred, it is effective by means of the electric machine lockup clutch 10 , the electric machine 1 to bridge. In this case, care must be taken that the torque converter lockup clutch 9 is open, so no power losses due to the rotating rotor of the electric machine 1 arise.

Bei dem hybridischen und dem elektrischen Betrieb des Hybrid-Planetengetriebes läuft die Elektromaschine 1 als Motor, d.h. die Elektromaschinenüberbrückungskupplung 10 ist offen, so dass Fahrleistung teilweise oder vollständig durch die Batterieladung aufgebracht wird, wenn die Wandlerüberbrückungskupplung 9 zu ist. Beim Bremsvorgang wird im Schubbetrieb die Elektromaschine 1 im Generatormodus bei geöffneter Elektromaschinenüberbrückungskupplung 10 betrieben, um die Bremsenergie zurück zuspeisen. In diesem Fall ist die Wandlerüberbrückungskupplung 9 offen. In the hybrid and the electric operation of the hybrid planetary gear, the electric machine is running 1 as an engine, ie the electric machine lockup clutch 10 is open, so that mileage is partially or completely applied by the battery charge when the lockup clutch 9 to is. During braking, the electric machine is in overrun mode 1 in generator mode with the electric machine lockup clutch open 10 operated to feed back the braking energy. In this case, the lockup clutch is 9 open.

Bei der vorgeschlagenen Lösung ist ein elektrisch-mechanischer Drehmomentwandler 1, 5 als Kombination von Planeten-Getriebe 5 und Elektromaschine 1 vorgeschlagen, bei welchen durch Überbrückungskupplungen ein gezieltes Aus- und Zuschalten von Systemkomponenten bei unterschiedlichen Betriebszuständen ermöglicht wird. Dabei können die Systemkomponenten in unterschiedlicher Reihenfolge angeordnet sein, wobei die Überbrückungskupplungen nach auch unterschiedlichen Wirkprinzipien arbeiten können. The proposed solution is an electric-mechanical torque converter 1 . 5 as a combination of planetary gears 5 and electric machine 1 proposed in which by bridging couplings targeted switching off and on of system components is made possible under different operating conditions. In this case, the system components can be arranged in different order, wherein the lock-up clutches can work according to different principles of action.
