Antriebsstrang für ein Fahrzeug Die vorliegende Erfindung betrifft einen Antriebsstrang gemäß dem Oberbegriff des Anspruches 1 und ein Verfahren zum Betreiben eines Antriebsstranges gemäß dem Oberbegriff des Anspruches 12.  The present invention relates to a drive train according to the preamble of claim 1 and to a method for operating a drive train according to the preamble of claim 12.
Stand der Technik State of the art
Kraftfahrzeuge die nur von einem Verbrennungsmotor angetrieben sind, das heißt mit fossilem Brennstoff, wie beispielsweise Benzin oder Gas, weisen einen hohen Kraftstoffverbrauch auf. Zur Reduzierung des Kraftstoffverbrauchs ist es bekannt, Kraftfahrzeuge als Fahrzeuge entweder als Hybridfahrzeuge von einemMotor vehicles that are powered only by an internal combustion engine, that is with fossil fuel, such as gasoline or gas, have a high fuel consumption. To reduce fuel consumption, it is known to motor vehicles as vehicles either as hybrid vehicles of one
Verbrennungsmotor und/oder einer Elektromaschine anzutreiben oder To drive internal combustion engine and / or an electric machine or
Fahrzeuge als reine Elektrofahrzeuge auszubilden, die ausschließlich von einer Elektromaschine angetrieben sind. Hybridfahrzeuge und Elektrofahrzeuge weisen bei dem Antrieb mit der Elektromaschine keine ausreichende Abwärme zum Erwärmen des Innenraums auf. Aufgrund des hohen Wirkungsgrads derTrain vehicles as pure electric vehicles, which are driven exclusively by an electric machine. Hybrid vehicles and electric vehicles in the drive with the electric machine do not have sufficient heat to heat the interior. Due to the high efficiency of the
Elektromaschine bei einem Betrieb als Elektromotor erreicht die an der Electric machine when operating as an electric motor reaches at the
Elektromaschine als Elektromotor anfallende Abwärme nicht aus, um den Innenraum zu erwärmen. Aus diesem Grund wird der Innenraum, bei einem Antrieb des Elektrofahrzeugs oder des Hybridfahrzeugs ausschließlich mit der Elektromaschine als Elektromotor, mit einer zusätzlichen elektrischen Electric machine as electric motor accumulating waste heat is not enough to heat the interior. For this reason, the interior, in a drive of the electric vehicle or the hybrid vehicle exclusively with the electric machine as an electric motor, with an additional electric
Widerstandsheizung erwärmt. In nachteiliger Weise ist deshalb eine zusätzliche aufwendige und kostspielige elektrische Widerstandsheizung, beispielsweise ein PTC-Zuheizer, notwendig. Die Elektromaschine und die Leistungselektronik sind als gesonderte  Resistance heating heated. Disadvantageously, therefore, an additional costly and expensive electrical resistance heating, for example, a PTC heater, necessary. The electric machine and the power electronics are as separate
Baueinheiten mit getrennten Gehäusen für die Elektromaschine und die Leistungselektronik ausgebildet. Die Leistungselektronik wandelt den Units with separate housings for the electric machine and the Power electronics trained. The power electronics converts the
Gleichstrom aus einer Batterie in Wechselstrom um zum Betrieb des DC power from a battery to AC to operate the
Elektromotors. Aus diesem Grund ist innerhalb des Fahrzeugs eine aufwendige Stromverbindung mit entsprechenden elektrischen Steckverbindern zwischen der Elektromaschine und der Leistungselektronik notwendig. Dies erfordert in nachteiliger weise einen zusätzlichen Montageaufwand und weitere Bauteile und Komponenten. Die Elektromaschine ist von einem Kühlkreislauf mit The electric motor. For this reason, a complex power connection with corresponding electrical connectors between the electric machine and the power electronics is necessary within the vehicle. This disadvantageously requires additional installation effort and other components and components. The electric machine is by a cooling circuit with
Kühlflüssigkeitsleitungen gekühlt. Eine Umwälzpumpe wälzt Kühlflüssigkeit in dem Kühlkreislauf bzw. in den Kühlflüssigkeitsleitungen um, sodass dadurch die Abwärme der Elektromaschine an einem Umgebungsluftwärmeübertrager an die Luft der Umgebung abgegeben werden kann. In Hybridfahrzeugen ist außer diesem Kühlkreislauf als Niedertemperaturkühlkreislauf zur Kühlung der Coolant lines cooled. A circulation pump circulates coolant in the cooling circuit or in the coolant lines, so that the waste heat of the electric machine can be discharged to an ambient air heat exchanger to the air of the environment. In hybrid vehicles is in addition to this cooling circuit as a low-temperature cooling circuit for cooling the
Elektromaschine auch noch ein Hochtemperaturkühlkreislauf vorhanden zur Kühlung des Verbrennungsmotors. Electric machine also has a high-temperature cooling circuit available for cooling the internal combustion engine.
Zur Kühlung der dem Innenraum des Fahrzeugs zuzuführenden Luft, For cooling the air to be supplied to the interior of the vehicle,
beispielsweise im Sommer bei hohen Außentemperaturen, ist ein Kältekreis vorhanden mit einem mechanischen Klimakompressor. Der mechanische Klimakompressor ist von einem gesonderten Elektromotor ausschließlich zum Antrieb des mechanischen Klimakompressors angetrieben. Dieser Elektromotor nur zum Antrieb des mechanischen Klimakompressors wird mit elektrischer Energie aus der Batterie angetrieben. Die Batterie ist im Allgemeinen eine Hochvolttraktionsbatterie mit der auch die Elektromaschine zum Antrieb des Fahrzeuges mit elektrischer Energie versorgt ist. In nachteiliger Weise ist dadurch ein zusätzlicher Elektromotor nur zum Antrieb des Klimakompressors notwendig. For example, in summer at high outside temperatures, a refrigerant circuit is present with a mechanical air compressor. The mechanical air conditioning compressor is driven by a separate electric motor exclusively for driving the mechanical air conditioning compressor. This electric motor only for driving the mechanical air compressor is powered by electrical energy from the battery. The battery is generally a high-voltage traction battery with which the electric machine for driving the vehicle is supplied with electrical energy. Disadvantageously, thereby an additional electric motor is only necessary to drive the air conditioning compressor.

Die Elektromaschine kann dadurch nicht nur zum Antrieb bzw. zur Traktion des Fahrzeugs eingesetzt werden, sondern zusätzlich auch zum Antrieb des mechanischen Klimakompressors. In vorteilhafter Weise ist dadurch kein zusätzlicher Elektromotor zum Power electronics with the evaporator. The electric machine can thereby be used not only to drive or traction of the vehicle, but also to drive the mechanical air compressor. Advantageously, this is no additional electric motor for

During the parking of the vehicle, that is, a state of the vehicle and a need for cooling in the interior can thus during the disengaged drive clutch and the coupled compressor clutch, the mechanical energy of the electric machine exclusively to the
Klimakompressor übertragen werden. Damit ist auch während des Parkens oder Stopps des Fahrzeugs eine Kühlung des Innenraums mittels des Kältekreises möglich, der von dem Klimakompressor angetrieben ist. Air compressor are transmitted.

Electric machine, the transmission, the air compressor, the compressor coupling means, preferably the drive coupling means and preferably the power electronics for the electric machine are arranged within a single or multi-part, common housing. Advantageously, separate housing, for example, for the electric machine, the transmission, the air compressor and the power electronics are not necessary.
