[0002] Die DE 10 2005 024 827 A1 beschreibt ein Antriebsaggregat eines Kraftfahrzeuges mit zumindest einer Verbrennungskraftmaschine zum Vortrieb des Kraftfahrzeuges, sowie einer Kühlvorrichtung zur Gewährleistung einer bedarfsgerechten Kühlung eines Antriebsaggregates. Die Kühlvorrichtung weist wenigstens einen Kühlmittelkreislauf auf, in dem wenigstens eine Kühlmittelpumpe angeordnet ist, wobei die Kühlmittelpumpe eine Koppelung mit der Verbrennungskraftmaschine und wenigstens einem Elektromotor aufweist. Aus der DE 10 2005 024 827 A1 ist es bekannt, eine Leistungselektronik und eine elektrische Maschine zu kühlen.DE 10 2005 024 827 A1 describes a drive unit of a motor vehicle with at least one internal combustion engine for propulsion of the motor vehicle, and a cooling device to ensure a demand-driven cooling of a drive unit. The cooling device has at least one coolant circuit, in which at least one coolant pump is arranged, wherein the coolant pump has a coupling with the internal combustion engine and at least one electric motor. From DE 10 2005 024 827 A1 it is known to cool power electronics and an electrical machine.

[0003] Weiters ist es aus der JP 2003 087 908 A2 bekannt, zwei der Elektromotoren parallel in einem geteilten Kühlkreislauf zu kühlen.Furthermore, it is known from JP 2003 087 908 A2 to cool two of the electric motors in parallel in a split cooling circuit.

[0004] Ferner ist es aus der DE 41 42 863 C2 bekannt, eine gemeinsame Leistungselektronik für mehrere Elektromotoren einzusetzen.Furthermore, it is known from DE 41 42 863 C2 to use a common power electronics for several electric motors.

[0005] Aufgabe der Erfindung ist es, auf einfache Weise bei einem Antriebsaggregat der Eingangs genannten Art eine ausreichende Kühlung zu gewährleisten.The object of the invention is to ensure a sufficient manner for a drive unit of the type mentioned sufficient cooling.

[0006] Erfindungsgemäß wird es dadurch erreicht, dass im gemeinsamen Kühlkreislauf zumindest eine Leistungselektronik angeordnet ist, wobei vorzugsweise die Leistungselektronik im gemeinsamen Kühlkreislauf stromaufwärts der elektrischen Maschinen angeordnet ist. Die Leistungselektronik kann im gemeinsamen Kühlkreislauf zwischen der Kühlmittelpumpe und den elektrischen Maschinen angeordnet sein.According to the invention, it is achieved that at least one power electronics is arranged in the common cooling circuit, wherein preferably the power electronics in the common cooling circuit upstream of the electrical machines is arranged. The power electronics can be arranged in the common cooling circuit between the coolant pump and the electrical machines.

[0007] In einer besonders Teile und Bauraum sparenden Ausführung der Erfindung ist vorgesehen, dass eine gemeinsame Leistungselektronik die zumindest zwei elektrischen Maschinen ansteuert.In a particularly parts and space-saving embodiment of the invention, it is provided that a common power electronics controls the at least two electric machines.

[0008] Um mit möglichst geringem Bauaufwand eine optimale Kühlung der elektrischen Maschinen zu ermöglichen, ist es besonders vorteilhaft, wenn stromabwärts der Leistungselektronik und stromaufwärts der elektrischen Maschinen im Kühlkreislauf zumindest ein Verteilventil angeordnet ist, welches den Kühlmittelstrom in zu jeweils einer elektrischen Maschine führende Kühlmittelzweige aufteilt, wobei vorzugsweise stromabwärts der elektrischen Maschinen sich die Kühlmittelzweige der elektrischen Maschinen zu einem gemeinsamen Kühlmittelströmungsweg vereinigen.In order to enable optimal cooling of the electrical machines with the least possible construction cost, it is particularly advantageous if downstream of the power electronics and upstream of the electrical machines in the cooling circuit at least one distribution valve is arranged, which the coolant flow in each leading to an electrical machine coolant branches preferably, downstream of the electrical machines, the coolant branches of the electrical machines unite to form a common coolant flow path.

[0009] Alternativ zu einer gemeinsamen Leistungselektronik kann für jede elektrische Maschine eine Leistungselektronik vorgesehen sein, wobei das Verteilerventil stromabwärts der Kühlmittelpumpe und stromaufwärts der Leistungselektroniken im Kühlkreislauf angeordnet sein kann, um den Kühlmittelstrom in zu jeweils einer Leistungselektronik und einer elektrischen Maschine führende Kühlmittelzweige aufzuteilen.As an alternative to a common power electronics power electronics can be provided for each electric machine, wherein the distribution valve downstream of the coolant pump and upstream of the power electronics can be arranged in the cooling circuit to divide the coolant flow in each leading to a power electronics and an electrical machine coolant branches.

[0010] Eine besonders kompakte Bauweise ergibt sich, wenn die elektrischen Maschinen, die Leistungselektronik, vorzugsweise auch das Kühlsystem, in einem gemeinsamen Gehäuse angeordnet sind.A particularly compact design results when the electrical machines, the power electronics, preferably also the cooling system, are arranged in a common housing.

[0011] Die Erfindung wird im Folgenden anhand der Fig. näher erläutert.The invention is explained in more detail below with reference to FIG.

[0012] Es zeigen schematisch [0013] Fig. 1 ein erfindungsgemäßes elektrisches Antriebsaggregat in einer ersten Ausfüh rungsvariante und 1 /5 österreichisches Patentamt AT512 492B1 2014-12-15 [0014] Fig. 2 ein erfindungsgemäßes elektrisches Antriebsaggregat in einer zweiten Ausfüh rungsvariante.1 shows an inventive electric drive unit in a first Ausfüh insurance variant and 1 Austrian Patent Office AT512 492B1 2014-12-15 Fig. 2 an inventive electric drive unit in a second Ausfüh insurance variant.

[0015] Die Fig. zeigen schematisch ein Antriebsaggregat 1 für ein Kraftfahrzeug, beispielsweise eine Elektrofahrzeug oder ein Flybridfahrzeug, wobei das Antriebsaggregat 1 eine erste elektrische Maschine 2 und eine zweite elektrische Maschine 3 aufweist. Jede elektrische Maschine 2, 3 weist einen Rotor 2a, 3a und einen kühlmittelgekühlten Stator 2b, 3b auf. Jeder Rotor 2a, 3a kann beispielsweise jeweils mit einer nicht weiter dargestellten Antriebswelle des Kraftfahrzeuges verbunden sein. Zur Kühlung jedes Stators 2b, 3b ist jeweils ein Kühlmantel 4, 5 um jeden Stator 2b, 3b vorgesehen, wobei jeder Kühlmantel 4, 5 einem gemeinsamen Kühlkreislauf 6 eines Kühlsystems K angehört. Die beiden Kühlmäntel 4, 5 sind im Kühlkreislauf 6 hydraulisch parallel angeordnet. Der Kühlkreislauf 6 weist eine gemeinsame Kühlmittelpumpe 7, welche elektrisch regelbar ausgeführt sein kann. Im Kühlkreislauf 6 ist weiters der Kühlmantel 8 einer in Fig. 1 für beide elektrischen Maschinen 2, 3 gemeinsamen Leistungselektronik 9 angeordnet, wobei im Ausführungsbeispiel gemäß Fig. 1 die Leistungselektronik 9 im gemeinsamen Kühlkreislauf 6 zwischen der Kühlmittelpumpe 7 und den beiden elektrischen Maschinen 4, 5 vorgesehen ist.The figures show schematically a drive unit 1 for a motor vehicle, such as an electric vehicle or a Flybridfahrzeug, wherein the drive unit 1, a first electric machine 2 and a second electric machine 3 has. Each electric machine 2, 3 has a rotor 2a, 3a and a coolant-cooled stator 2b, 3b. Each rotor 2a, 3a may be connected, for example, each with a drive shaft of the motor vehicle, not shown. For cooling each stator 2b, 3b, a cooling jacket 4, 5 is provided around each stator 2b, 3b, each cooling jacket 4, 5 belonging to a common cooling circuit 6 of a cooling system K. The two cooling jackets 4, 5 are arranged hydraulically in parallel in the cooling circuit 6. The cooling circuit 6 has a common coolant pump 7, which can be made electrically adjustable. In the cooling circuit 6, the cooling jacket 8 is further arranged in FIG. 1 for both electric machines 2, 3 common power electronics 9, wherein in the embodiment of FIG. 1, the power electronics 9 in the common cooling circuit 6 between the coolant pump 7 and the two electric machines 4, 5 is provided.

[0016] In der in Fig. 1 dargestellten Ausführung ist stromabwärts des Kühlmantels 8 der Leistungselektronik 9 im Kühlkreislauf 6 ein Verteilerventil 14 angeordnet, welches beispielsweise als Dreiwegventil ausgebildet sein kann. Mit dem Verteilerventil 14 können die über Kühlmittelzweige 10a, 11a den Kühlmäntel 4, 5 der elektrischen Maschinen 2, 3 zugeführten Mengen an Kühlmittel gesteuert werden.In the embodiment shown in Fig. 1, downstream of the cooling jacket 8 of the power electronics 9 in the cooling circuit 6, a distribution valve 14 is arranged, which may be formed, for example, as a three-way valve. With the distribution valve 14, the quantities of coolant supplied via coolant branches 10a, 11a to the cooling jackets 4, 5 of the electrical machines 2, 3 can be controlled.

[0017] Wie in Fig. 2 gezeigt ist, kann alternativ zu einer gemeinsamen Leistungselektronik kann für jede elektrische Maschine 2, 3 eine separate Leistungselektronik 9 vorgesehen sein, wobei das Verteilerventil 14 in diesem Fall stromabwärts der Kühlmittelpumpe 7 und stromaufwärts der beiden Leistungselektroniken 9 im Kühlkreislauf 6 angeordnet sein kann, um den Kühlmittelstrom in zu jeweils einer Leistungselektronik 9 und einer elektrischen Maschine 2, 3 führende Kühlmittelzweige 10a, 10b aufzuteilen.As shown in Fig. 2, may be provided as an alternative to a common power electronics for each electric machine 2, 3, a separate power electronics 9, wherein the distribution valve 14 in this case downstream of the coolant pump 7 and upstream of the two power electronics 9 im Cooling circuit 6 may be arranged to divide the coolant flow in each of a power electronics 9 and an electric machine 2, 3 leading coolant branches 10a, 10b.

[0018] Stromabwärts der Kühlmäntel 4, 5 der beiden elektrischen Maschinen 2, 3 vereinigen sich die Rücklaufleitungen 10b, 11b zu einer gemeinsamen Rücklaufleitung 12, welche zur Kühlmittelpumpe 7 führt.Downstream of the cooling jackets 4, 5 of the two electric machines 2, 3, the return lines 10b, 11b combine to form a common return line 12, which leads to the coolant pump 7.

[0019] Die Leistungselektronik 9 bzw. die Leistungselektroniken 9 für die beiden elektrischen Maschinen 2, 3 ist bzw. sind in ein gemeinsames Gehäuse 13 verbaut. Dies hat den Vorteil, dass alle zu kühlenden Teile der Leistungselektronik 9 durch eine gemeinsame Kühlmittelpumpe 7 versorgt werden können. Die Aufteilung auf die einzelnen elektrischen Maschinen 2, 3 wird über das Verteilerventil 14 geregelt. In den Fig. ist das Verteilerventil 14 stromabwärts bzw. stromaufwärts der Leistungselektronik 9 bzw. der Leistungselektroniken 9 dargestellt. Das Verteilerventil 14 kann alternativ dazu aber auch in der Leistungselektronik 9 verbaut sein.The power electronics 9 and the power electronics 9 for the two electric machines 2, 3 is or are installed in a common housing 13. This has the advantage that all parts of the power electronics 9 to be cooled can be supplied by a common coolant pump 7. The distribution to the individual electric machines 2, 3 is regulated via the distributor valve 14. In the figures, the distribution valve 14 downstream or upstream of the power electronics 9 and the power electronics 9 is shown. The distribution valve 14 may alternatively be installed in the power electronics 9 but also.

[0020] Somit können beide elektrischen Maschinen, 4, 5 parallel mit Kühlmittel durch eine einzige Kühlmittelpumpe 7 versorgt werden. 2/5Thus, both electric machines, 4, 5 can be supplied in parallel with coolant through a single coolant pump 7. 2.5
