Aufgabe der Erfindung ist es, einen weiteren komfortablen Hybrid-Antriebsstrang zu schaffen.task The invention is another convenient hybrid powertrain to accomplish.
Der Hybrid-Antriebsstrang umfasst dabei einen Verbrennungsmotor und zwei Elektromaschinen. Zur Leistungsverteilung und Übersetzung sind ein Überlagerungsgetriebe und ein Übersetzungsgetriebe vorgesehen. Das vordere Überlagerungsgetriebe kann insbesondere mit einem Ravignaux-Satz ausgeführt sein, wohingegen das hintere Überlagerungsgetriebe mit einem oder mehreren Planetensätzen oder einem Ravignaux-Satz ausgeführt sein kann. Über Kupplungen bzw. Bremsen sind das Überlagerungsgetriebe und das Übersetzungsgetriebe und das Getriebegehäuse miteinander gekoppelt. In einer besonders vorteilhaften Ausgestaltung der Erfindung ist diese Kopplung dabei derart, dass neun fest Gänge sowie drei stufenlose Fahrbereiche entstehen. In besonders vorteilhafter Weise kann die Koppelung derart sein, dass ein Wechsel bzw. eine Schaltung zwischen stufenlosen Fahrbereichen und festen Gängen jederzeit möglich ist. Dabei können die Geschwindigkeiten der Wellen derart aneinander angeglichen – d.h. synchronisiert – sein, dass diese Schaltungen ruckfrei erfolgen.Of the Hybrid powertrain includes an internal combustion engine and two electric machines. For power distribution and translation are a superposition gearbox and a transmission gear intended. The front superposition gear can be executed in particular with a Ravignaux set, whereas the rear superposition gear with one or more planetary gear sets or a Ravignaux set accomplished can be. about Clutches or brakes are the superposition gear and the transmission gear and the gearbox coupled together. In a particularly advantageous embodiment The invention, this coupling is such that nine fixed gears and Three stepless driving ranges arise. In particularly advantageous Way the coupling can be such that a change or a Circuit between stepless driving ranges and fixed gears at any time possible is. It can the velocities of the waves are aligned with each other - i.e. be synchronized - that these circuits are made smoothly.
Gemäß einem Vorteil der Erfindung bietet der Hybrid-Antriebsstrang die Möglichkeit der Bremsenergie-Rekuperation. Dabei wird die Bremsenergie genutzt, um eine oder beide Elektromaschinen beim Abbremsen des Fahrzeugs generatorisch zu betreiben, so dass die durch das Abbremsen gewonnene Energie in einen Energiespeicher eingespeist werden kann. Ein solcher Energiespeicher kann insbesondere eine Batterie oder eine Kondensator sein.According to one Advantage of the invention, the hybrid powertrain offers the possibility of braking energy recuperation. The braking energy is used to one or both electric machines to operate as a generator when braking the vehicle, so that the energy gained by deceleration in an energy storage can be fed. Such an energy store can in particular a battery or a capacitor.
Ferner kann gespeicherte Energie genutzt werden, um Anfahr- und Beschleunigungsvorgänge des Verbrennungsmotors im so genannten Boost-Betrieb zu unterstützen.Further stored energy can be used to start and accelerate the Combustion engine to support in the so-called boost operation.
Der Hybrid-Antriebsstrang ermöglicht es, den Verbrennungsmotor ohne zusätzlichen Anlassermotor vom Stillstand in den Betrieb zu setzen, so dass ein Start-Stop-Betrieb ohne Zusatzaufwand möglich ist.Of the Hybrid powertrain allows it, the internal combustion engine without additional starter motor from Set standstill in the operation, so that a start-stop operation without additional effort is possible.
In stufenlosen Fahrbereichen ist es möglich das Übersetzungsverhältnis stufenlos zu verändern.In stepless driving ranges, it is possible the gear ratio stepless to change.
Der Antriebsstrang kann auch rein elektrisch von einem oder beiden Elektromaschinen angetrieben werden.Of the Powertrain can also be purely electrical from one or both electric machines are driven.
In einer besonders kostengünstigen und leichten Ausgestaltung der Erfindung sind im Übersetzungsgetriebe mehrere Übersetzungen vorgesehen, so dass drei stufenlose Fahrbereiche bereitgestellt werden. Infolgedessen können die Elektromaschinen und die Leistungselektronik entsprechend klein ausgelegt werden. In dieser oder einer anderen Ausgestaltung können ferner neun feste Gänge vorgesehen sein, so dass bei konstanter Fahrt bzw. im Schleppbetrieb die Leistungsübertragung rein mechanisch – d.h. nicht elektrisch – erfolgt, so dass nur geringe elektrische Verluste auftreten. Damit ist auch die abzuführende Wärme des Systems relativ gering. Der Wirkungsgrad kann ferner durch Verringerung des elektrischen Anteils in der Leistungsverzweigung verbessert werden.In a particularly cost-effective and easy embodiment of the invention are in the transmission gear several translations provided so as to provide three stepless driving ranges become. As a result, can the electric machines and the power electronics are correspondingly small be interpreted. In this or another embodiment may further nine fixed gears be provided so that at constant speed or in towing the power transmission purely mechanical - i. not electric - done, so that only small electrical losses occur. This is also the dissipated Heat of the Systems relatively low. The efficiency can be further reduced by reducing the electric share in the power split.

In sämtlichen Ausgestaltungsformen können die Kupplungen und Bremsen als reibschlüssige Lamellenkupplung, als formschlüssige Klauenkupplung oder als Mischform entsprechend einer Synchronkupplung eines Vorgelegegetriebes ausgeführt sein.In all Ausgestaltungsformen can Clutches and brakes as frictional multi-plate clutch, as positive Claw coupling or as a mixed form corresponding to a synchronous coupling executed a countershaft transmission be.
In manchen Betriebeszuständen kann das Fahren in einem stufenlosen Fahrbereiches sogar vom Wirkungsgrad her günstiger sein, als in einem festen Gang.In some operating conditions Driving in a stepless driving range can even be more efficient cheaper be as in a fixed gear.
Die Gangabstufung der festen Gänge ist konzeptbedingt geometrisch und damit nicht progressiv. Um diese Abweichung von der für PKW-Getriebe gewünschten progressiven Gangabstufen zu kompensieren, wird der Hybrid-Antriebsstrang nicht direkt von einem Gang in den nächsten geschaltet. Stattdessen wird so lange stufenlos in einem der Fahrbereiche gefahren, bis sich die Wellengeschwindigkeiten für den nächsten Gang angeglichen haben. Somit ist auch ohne Schaltkomforteinbußen die Verwendung von Klauenkupplungen möglich, da durch die beiden Elektromaschinen die Wellengeschwindigkeiten der wellen für den nächsten Gang bzw. den Fahrbereich angeglichen werden können. So ist ein völlig ruckloser Schaltvorgang möglich. Ferner ist ein zugkraftunterbrechungsfreies Schalten auch bei
