Aufgabe der Erfindung ist, einen hybridisierten Antriebsstrang zu schaffen, der eine einfache Montage ermöglicht und die Prüfung der Funktionalität des Hybridmoduls vor dessen Montage im hybridisierten Antriebstrang ermöglicht.The object of the invention is to provide a hybrid powertrain, which allows easy assembly and allows the testing of the functionality of the hybrid module before its assembly in the hybrid powertrain.

Diese Aufgabe wird durch einen hybridisierten Antriebsstrang nach Anspruch 1 gelöst. This object is achieved by a hybridized drive train according to claim 1.

Der erfindungsgemäße hybridisierte Antriebsstrang besteht im Wesentlichen aus einem Elektromotor und einem Getriebe, die mit einem Kupplungssystem zur Übertragung einer Antriebskraft des Verbrennungsmotors und/oder des Elektromotors auf das Getriebe verbunden sind. Der Elektromotor besteht aus einem Rotor und einem Stator. Das Kupplungssystem trägt den Rotor. Der Stator ist an einem Kühlmantel montiert und bildet somit ein Einschubmodul. Der Kühlmantel ist mit einem Gehäuseteil des Antriebsstrangs und dem Kupplungssystem verbunden.The hybridized drive train according to the invention consists essentially of an electric motor and a transmission, which are connected to a clutch system for transmitting a driving force of the internal combustion engine and / or the electric motor to the transmission. The electric motor consists of a rotor and a stator. The coupling system carries the rotor. The stator is mounted on a cooling jacket and thus forms a plug-in module. The cooling jacket is connected to a housing part of the drive train and the coupling system.

Der Rotor des Elektromotors ist drehfest mit dem Kupplungssystem verbunden. Das Einschubmodul ist zwischen dem Gehäuseteil und dem Rotor angeordnet. Gemäß einer Ausführungsform der Erfindung trägt der Kühlmantel mindestens ein Dichtelement, das mit dem Gehäuseteil dichtend zusammenwirkt. Ebenso kann die dichtende Wirkung gemäß einer zweiten Ausführungsform realisiert werden. Bei dieser Ausführungsform trägt der Kühlmantel trägt mindestens ein erstes Dichtelement, das mit mindestens einem zweiten Dichtelement am Gehäuseteil zusammenwirkt.The rotor of the electric motor is rotatably connected to the coupling system. The plug-in module is arranged between the housing part and the rotor. According to one embodiment of the invention, the cooling jacket carries at least one sealing element which seals with the housing part interacts. Likewise, the sealing effect can be realized according to a second embodiment. In this embodiment, the cooling jacket carries at least one first sealing element, which cooperates with at least one second sealing element on the housing part.

Eine Stromzuführung für den Stator ist über das Gehäuseteil vor dem Einschub des Stators herstellbar. Beim Einschub des Einschubmoduls werden die erforderlichen elektrischen Kontakte mit dem Stator hergestellt. Der Kühlmantel, der den Stator trägt, ist mit Schrauben am Gehäuseteil und am Kupplungssystem montiert. Bevorzugt ist das Gehäuseteil und das Kupplungssystem zur Befestigung des Kühlmantels zwischen dem Motor und dem Getriebe angeordnet.A power supply for the stator can be produced via the housing part before the insertion of the stator. When inserting the plug-in module, the required electrical contacts are made with the stator. The cooling jacket, which carries the stator, is mounted with screws on the housing part and on the coupling system. Preferably, the housing part and the coupling system for fixing the cooling jacket between the engine and the transmission is arranged.

Der Kühlmantel ist gleichzeitig der Träger für den Stator. Das Einschubmodul kann unabhängig vom Gehäuseteil des hybridisierten Antriebsstrangs montiert und mit elektrischen Anschlüssen versehen werden. Der Vorteil hiervon ist, dass es sich um ein Baukastensystem handelt, das bei verschiedenen Außengehäusen eingesetzt werden kann. Ebenso ist vor der Montage des Einschubmoduls eine Funktionsprüfung möglich.The cooling jacket is at the same time the carrier for the stator. The plug-in module can be mounted independently of the housing part of the hybrid powertrain and provided with electrical connections. The advantage of this is that it is a modular system that can be used in various outdoor enclosures. Likewise, a functional test is possible before mounting the plug-in module.

Bei der in 2 gezeigten Ausführungsform trägt der Kühlmantel 10 trägt mindestens ein erstes Dichtelement 14, das mit mindestens einem zweiten Dichtelement 15 am Gehäuseteil 13 zusammenwirkt. Die hier dargestellte Anordnung zur Dichtung stellt eine von mehreren Ausführungsformen das und soll nicht als Beschränkung der Erfindung aufgefasst werden. 2 shows a schematic partial view of the hybridized powertrain 1 in which the present invention is used. Analogous to the prior art is an electric motor 7 provided that a rotor 8th and a stator nine includes and with a coupling system 11 connected is. The rotor 8th of the electric motor 7 is with the coupling system 11 rotatably connected. The coupling system 11 serves to transmit a driving force of an internal combustion engine 3 and / or the electric motor 7 on the gearbox 5 , The rotor 8th of the electric motor 7 is from the coupling system 11 carried. According to the invention, the stator nine on a cooling jacket 10 assembled. The cooling jacket 10 and the stator nine together form a plug-in module 100 , The cooling jacket 10 is with a housing part 13 of the powertrain 1 and the coupling system 11 connected. The plug-in module 100 is between the housing part 13 and the rotor 8th inserted and is arranged there. At the in 2 Shown embodiment, the cooling jacket carries 10 carries at least a first sealing element 14 that with at least one second sealing element 15 on the housing part 13 interacts. The arrangement for sealing illustrated here is one of several embodiments and is not to be construed as limiting the invention.

Die erfindungsgemäße Ausgestaltung ist von Vorteil, da eine Stromzuführung 16 für den Stator 9 über das Gehäuseteil 13 ausgebildet ist. Vor dem Einschub des Stators 9 zwischen das Gehäuseteil 13 und dem Rotor 8, können alle erforderlichen elektrischen Anschlüsse konfiguriert werden. Beim Einschub werden dann die Kontakte für die Stromzuführung 16 geschlossen. Der Kühlmantel 10 selbst ist mit Schrauben 20 am Gehäuseteil 13 und am Kupplungssystem 11 montiert ist. Der Kühlmantel 10 dient gleichzeitig als Träger für den Stator 9. Es ist für einen Fachmann selbstverständlich, dass auch andere Verbindungsmöglichkeiten zwischen dem Kühlmantel 10 und dem Gehäuseteil 13 möglich sind. Die einzige Bedingung ist, dass die Verbindung lösbar ausgebildet sein muss.The embodiment of the invention is advantageous because a power supply 16 for the stator nine over the housing part 13 is trained. Before the insertion of the stator nine between the housing part 13 and the rotor 8th , all required electrical connections can be configured. When inserting then the contacts for the power supply 16 closed. The cooling jacket 10 itself is with screws 20 on the housing part 13 and at the coupling system 11 is mounted. The cooling jacket 10 serves as a support for the stator at the same time nine , It is obvious to a person skilled in the art that other possibilities of connection between the cooling jacket 10 and the housing part 13 possible are. The only condition is that the connection must be detachable.

Weitere Elemente der 2 sind bereits ausführlich in der vorherstehenden Figurenbeschreibung beschrieben.Other elements of 2 are already described in detail in the preceding description of the figures.

Die Erfindung wurde unter Bezugnahme auf ein bevorzugtes Ausführungsbeispiel beschrieben. Es ist jedoch für jeden Fachmann selbstverständlich, dass Abwandlungen und Änderungen vorgenommen werden können, ohne dabei den Schutzbereich der nachstehenden Ansprüche zu verlassen. Die voran stehend erörterten Ausführungsbeispiele dienen lediglich zur Beschreibung der beanspruchten Lehre, schränken diese jedoch nicht auf die Ausführungsbeispiele ein. The invention has been described with reference to a preferred embodiment. However, it will be understood by those skilled in the art that modifications and changes may be made without departing from the scope of the following claims. The embodiments discussed above are merely for the purpose of describing the claimed teaching, but do not limit it to the embodiments.
