Je nach Anwendungsbereich ist es vorteilhaft, dass zumindest auf der Abtriebswelle, auf der Eingangswelle oder auf der Zwischenwelle ein Torsionsdämpfer vorgesehen ist. Dadurch wird erreicht, dass gerade bei geringen Schwungmassen die Spitzenbelastungen reduziert werden.ever According to application, it is advantageous that at least on the Output shaft, on the input shaft or on the intermediate shaft a torsion damper is provided. This ensures that just at low Flywheels the peak loads are reduced.
Ein erfindungsgemäßes Verfahren zum Betrieb eines Antriebsstrangs ist dadurch gekennzeichnet, dass im gesamten Antriebsstrang maximal ein elektrisches Antriebsaggregat integriert ist, das als Motor oder als Generator betrieben wird. Dadurch wird erreicht, dass das Verfahren zum Betreiben eines Antriebsstrangs für einen Hybridmotor wesentlich vereinfacht und der Wirkungsgrad des gesamten Systems vergrößert wird. Die Verluste, die durch ein zweites elektrisches Antriebsaggregat und durch weitere notwendige Getriebeglieder erzeugt würden, werden vermieden. Das Verfahren zum Betreiben des Antriebsstrangs wird dadurch vereinfacht, dass die Anzahl von schaltbaren Getriebegliedern und die Steuerung eines zweiten elektrischen Antriebsaggregats entfällt.One inventive method for operating a drive train is characterized in that in the entire drive train maximum one electric drive unit integrated, which is operated as a motor or as a generator.

Besonders vorteilhaft für das Verfahren ist es, dass während des Fahrbetriebs nach Maßgabe von Betriebsbedingungen des Antriebsstrangs in Teilbetriebsbereichen ein reiner Antrieb durch die Brennkraftmaschine erfolgt. Auch mit nur einem elektrischen Antriebsaggregat lässt sich das Verfahren zum Betreiben des Antriebsstrangs erfindungsgemäß derart gestalten, dass die Brennkraftmaschine konventionell ohne elektrisches Antriebsaggregat das Fahrzeug antreibt.Especially advantageous for the procedure is that during driving according to Operating conditions of the powertrain in sub-operating areas a pure drive by the internal combustion engine takes place.
