BeschreibungDescription

Kraftfahrzeug-Antrieb mit einem ElektromotorMotor vehicle drive with an electric motor

Die Erfindung bezieht sich auf einen Kraftfahrzeug-Antrieb mit einem Elektromotor gemäß Anspruch 1.The invention relates to a motor vehicle drive with an electric motor according to claim 1.

Kraftfahrzeug-Antriebe mit einem Elektromotor sind als reine Elektromotor-Antriebe oder als sogenannte Hybrid-Antriebe in Kombination mit einem Verbrennungsmotor z.B. durch die DE-OS-24 00 760 bzw. die EP-Bl-O 506 805 bekannt. Bei derartigen Antrieben ist die Rotorwelle des Elektromotors, der betriebsmäßig auch als Generator arbeiten kann, mit ihrem einen Wellenende koaxial starr direkt oder indirekt über ein zwischengeschaltetes Getriebe mit den Rädern des Kraftfahrzeuges und gegebenenfalls auch mit dem anderen Ende ihrer Rotorwelle direkt oder indirekt mit einen Verbrennungsmotor jeweils koaxial starr gekoppelt. Da die derart koaxial starr gekoppelten weiteren Antriebsaggregate, insbesondere das Getriebe bzw. der Verbrennungsmotor, insbesondere auch hinsichtlich ihrer Wellenausgänge, kundenspezifisch entsprechend den unterschiedlichen Kraftfahrzeug-Modellen der jeweiligen Kraftfahrzeug-Hersteller ausgestaltet sind, ist der Elektromotor, zumindest hinsichtlich seiner abtriebs- bzw. antriebsseitigen Rotorwellen-Ankopplung, individuell entsprechend den kundenspezifischen Unterschieden auszulegen.Motor vehicle drives with an electric motor are known as pure electric motor drives or as so-called hybrid drives in combination with an internal combustion engine, for example through DE-OS-24 00 760 or EP-Bl-O 506 805. In such drives, the rotor shaft of the electric motor, which can also operate as a generator, is coaxially rigidly coupled with one shaft end directly or indirectly via an intermediate gear to the wheels of the motor vehicle and, if necessary, also with the other end of its rotor shaft directly or indirectly to an internal combustion engine. Since the other drive units that are rigidly coupled in this way, in particular the gearbox or the combustion engine, are designed in a customer-specific manner, particularly with regard to their shaft outputs, in accordance with the different vehicle models of the respective vehicle manufacturers, the electric motor, at least with regard to its output-side or drive-side rotor shaft coupling, must be designed individually in accordance with the customer-specific differences.

Gemäß Aufgabe vorliegender Erfindung soll ein Kraftfahrzeug-Antrieb mit einem Elektromotor geschaffen werden, durch den 0 der Fertigungsaufwand, insbesondere hinsichtlich der Herstellung der Elektromotore, für verschiedene derartige Kraftfahrzeug-Antriebe, minimiert werden kann.According to the object of the present invention, a motor vehicle drive with an electric motor is to be created, by means of which the manufacturing effort, in particular with regard to the manufacture of the electric motors, for various such motor vehicle drives can be minimized.

Die Lösung dieser Aufgabe gelingt durch die Lehre des An-Spruchs 1; vorteilhafte Ausgestaltungen sind jeweils Gegenstand der Unteransprüche.This problem is solved by the teaching of claim 1; advantageous embodiments are the subject of the subclaims.

GR 96 G 3133GR 96 G 3133

Bei dem erfindungsgemäßen Kraftfahrzeug-Antrieb ist es möglich, trotz eines größeren unterschiedlichen kundenspezifischen Ausführungsspektrums der an den Elektromotor anzukoppelnden weiteren Antriebsaggregate die Elektromotore zu gleichartigen Fertigungslosen zusammenzufassen und eine kundenspezifische Zuordnung erst am Ende der Fertigung und Montage durch lediglich ein individuell anzupassendes Adapter-Kopplunngssück sicherzustellen.In the motor vehicle drive according to the invention, it is possible, despite a large range of different customer-specific designs of the additional drive units to be coupled to the electric motor, to combine the electric motors into similar production batches and to ensure a customer-specific assignment only at the end of production and assembly by means of only an individually adaptable adapter coupling piece.

Die Erfindung sowie weitere vorteilhafte Ausgestaltungen der Erfindung gemäß Merkmalen der Unteransprüche werden im folgenden anhand schematisch dargestellter Ausführungsbeispiele in der Zeichnung näher erläutert; darin zeigen:The invention and further advantageous embodiments of the invention according to the features of the subclaims are explained in more detail below using schematically illustrated embodiments in the drawings; in which:

in Explosionsdarstellung drei verschiedene Ausführungen eines Kraftfahrzeug-Antriebs mit einem Elektromotor und mit daran über eine koaxial starre Wellenverbindung anzukoppelnder weiterer Antriebsaggregate; in an exploded view three different versions of a motor vehicle drive with an electric motor and with additional drive units to be coupled to it via a coaxial rigid shaft connection;

in vergrößerter Darstellung einen Elektromotor mit einer standardisierten, zur Aufnahme eines Adapter-Kopplungsstückes vorgesehenen Rotorwelle; verschiedene Ausführungen eines Adapter-Verbindungsstückes jeweils in axialer Seitenansicht und stirnseitiger Draufsicht.an enlarged view of an electric motor with a standardized rotor shaft designed to accommodate an adapter coupling piece; various versions of an adapter connecting piece, each in an axial side view and a frontal top view.

FIG 1 zeigt in Explosionsdarstellung den Prinzipaufbau eines reinen Elektro-Kraftfahrzeug-Antriebes, bei dem das eine Ende einer Rotorwelle 1.1 eines Elektromotors 1 mit einer Welle 2.1 eines Getriebes 2 jeweils über ein Adapter-Kopplungsstück 6 koaxial starr zu koppeln ist.FIG 1 shows an exploded view of the basic structure of a purely electric motor vehicle drive, in which one end of a rotor shaft 1.1 of an electric motor 1 is to be rigidly coupled coaxially to a shaft 2.1 of a transmission 2 via an adapter coupling piece 6.

FIG 2 zeigt in Explosionsdarstellung den Prinzipaufbau eines Hybrid-Kraftfahrzeug-Antriebes, bei dem das eine Wellenende einer Rotorwelle 1.1 eines Elektromotors 1 mit dem Wellenende einer Welle 2.1 eines Getriebes 2 und das andere WellenendeFIG 2 shows an exploded view of the basic structure of a hybrid motor vehicle drive, in which one shaft end of a rotor shaft 1.1 of an electric motor 1 is connected to the shaft end of a shaft 2.1 of a transmission 2 and the other shaft end

GR 96 G 3133GR 96 G 3133

der Rotorwelle 1.1 mit dem Wellenende der Welle 3.1 eines Verbrennungsmotors 3 jeweils über ein Adapter-Kopplungsstück 6 koaxial starr zu koppeln ist.the rotor shaft 1.1 is to be rigidly coupled coaxially to the shaft end of the shaft 3.1 of an internal combustion engine 3 via an adapter coupling piece 6.

FIG 3 zeigt wiederum in Explosionsdarstellung den Prinzipaufbau eines reinen Elektro-Kraftfahrzeug-Antriebs, bei dem das eine Wellenende einer Rotorwelle 1.1 eines Elektromotors 1 mit einem Wellenenende 4.1 eines Kardanwellenteils 4 und das andere Wellenende der Rotorwelle 1.1 mit dem Wellenende 5.1 des anderen Kardanwellenteils 5 jeweils über ein Adapter-Kopplungsstück 6 koaxial starr zu koppeln ist.FIG 3 again shows in exploded view the basic structure of a purely electric motor vehicle drive, in which the one shaft end of a rotor shaft 1.1 of an electric motor 1 is to be rigidly coupled coaxially with a shaft end 4.1 of a cardan shaft part 4 and the other shaft end of the rotor shaft 1.1 with the shaft end 5.1 of the other cardan shaft part 5, each via an adapter coupling piece 6.

FIG 4 zeigt in vergrößerter Darstellung einen für einen erfindungsgemäßen Kraftfahrzeug-Antrieb ausgerüsteten Universal-Elektromotor 1. Am Innenumfang eines Motorgehäuses 1.2 ist ein mit einer Statorwicklung 1.4 versehenes Statorblechpaket 1.3 gehalten. An den beiden stirnseitigen Enden des Motorgehäuses 1.2 ist je ein Lagerschild 1.5 bzw.1.6 befestigt, in dem über Kugellager 1.7 bzw.1.8 eine Rotorwelle 1.1 gelagert ist.FIG 4 shows an enlarged view of a universal electric motor 1 equipped for a motor vehicle drive according to the invention. A stator laminated core 1.3 provided with a stator winding 1.4 is held on the inner circumference of a motor housing 1.2. A bearing plate 1.5 or 1.6 is attached to each of the two front ends of the motor housing 1.2, in which a rotor shaft 1.1 is mounted via ball bearings 1.7 or 1.8.

Die Rotorwelle 1.1 weist an ihren beiden Enden jeweils eine Einsteckbohrung 1.11 bzw.1.12 zur Aufnahme des einen Wellenendes 6.1 des Adapter-Kopplungsstückes 6 auf, mit dessen anderem Wellenende 6.2 das eine Wellenende 2.1 bzw. 3.1 bzw.4.1 bzw.5.1 des weiteren Aggregates 2 bzw.3 bzw.4 bzw.5 starr gekoppelt ist. Die Ausbildung einer solchen Einsteckbohrung wird dadurch erleichtert, daß die Rotorwelle 1.1 in vorteilhafter Weise als Hohlwelle ausgebildet ist. Durch die axial in die Rotorwelle 1.1 eintauchende Einsteckbohrung 1.11 bzw.1.12 kann außerdem eine axiale kompakte Bauweise durch direkte stirnseitige Anlage von Elektromotor 1 einerseits und weiterem Antriebsaggregat 2-5 andererseits erreicht werden. Der Elektromotor 1 kann ist somit trotz unterschiedlicher 5 kundenspezifischer Antriebsaggregate 2-5 mit entsprechenden unterschieldichen Wellenenden als Einheitsmotor ausführbarThe rotor shaft 1.1 has an insertion hole 1.11 or 1.12 at each of its two ends to accommodate one shaft end 6.1 of the adapter coupling piece 6, with the other shaft end 6.2 of which one shaft end 2.1 or 3.1 or 4.1 or 5.1 of the further unit 2 or 3 or 4 or 5 is rigidly coupled. The formation of such an insertion hole is made easier by the fact that the rotor shaft 1.1 is advantageously designed as a hollow shaft. The insertion hole 1.11 or 1.12 which penetrates axially into the rotor shaft 1.1 also enables an axially compact design to be achieved by directly connecting the electric motor 1 on the one hand and the further drive unit 2-5 on the other. The electric motor 1 can therefore be designed as a standard motor despite different 5 customer-specific drive units 2-5 with correspondingly different shaft ends

Dabei sind die an die kundenspezifisch unterschiedliche Wellenenden 2.1-5.1 des weiteren Antriebsaggregates 2-5 anzupassenden Kopplungs-Wellenenden 6.2 nicht im Einzelnen ausgeführt; die Figuren 5-14 sollen lediglich verschiedene Möglichkeiten der kraft- bzw. formschlüssigen Momentenübertragung zwischen dem elektromotorseitigen Kopplungs-Wellenende 6.1 des Adapter-Kopplungsstückes 6 und dem entsprechenden Wellenende der Rotorwelle 1.1, insbesondere der bereits beschriebenen Einsteckbohrung 1.11 bzw. 1.12 des Elektromotors 1, verdeutlichen.FIGS 5-14 show, in a side view and in a front view, five different versions of an adapter coupling piece 6 with a first coupling shaft end 6.1 on the electric motor side and a second coupling shaft end 6.2 on the drive unit side. The coupling shaft ends 6.2 to be adapted to the customer-specific different shaft ends 2.1-5.1 of the further drive unit 2-5 are not shown in detail; Figures 5-14 are only intended to illustrate various options for force-locking or form-locking torque transmission between the coupling shaft end 6.1 on the electric motor side of the adapter coupling piece 6 and the corresponding shaft end of the rotor shaft 1.1, in particular the already described insertion hole 1.11 or 1.12 of the electric motor 1.

FIG 5,6 zeigen ein Adapter-Kopplungsstück 6, dessen elektromotorseitiges erstes Kopplungs-Wellenende 6.1 kraftschlüssig in der Einsteckbohrung 1.11 bzw.1.12, z.B. durch Schrumpfen, Einpressen, Verklemmen oder Verkleben, im Sinne einer hinreichenden Momentenübertragung fixierbar ist.FIGS. 5 and 6 show an adapter coupling piece 6, the first coupling shaft end 6.1 of which on the electric motor side can be fixed in a force-locking manner in the insertion bore 1.11 or 1.12, e.g. by shrinking, pressing in, clamping or gluing, in order to ensure sufficient torque transmission.

FIG 13,14 zeigen eine dazu vereinfachte Einführung zum vorteilhaften axialen Einstecken des Adapter-Kopplungsstückes 6 mittels einer konischen Ausbildung des elektromotorseitigen ersten Kopplungs-Wellenendes 6.1.FIGS. 13, 14 show a simplified introduction for the advantageous axial insertion of the adapter coupling piece 6 by means of a conical design of the first coupling shaft end 6.1 on the electric motor side.

FIG 7-11 bzw. 8-12 zeigen verschiedene Ausführungen des Adapter-Kopplungsstückes 6 mit einer formschlüssigen Drehmomentenmitnahme mittels einer Innenverzahnung nach FIG 7,8 oder einer Außenverzahnung nach FIG 9,10 oder einer Vielkantprofilierung gemäß FIG 11,12.FIGS 7-11 and 8-12 show different designs of the adapter coupling piece 6 with a positive torque transmission by means of an internal toothing according to FIGS 7,8 or an external toothing according to FIGS 9,10 or a polygonal profile according to FIGS 11,12.
