Description

Die vorliegende Erfindung betrifft eine Befestigungsanordnung einer elektrischen Maschine gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art.The present invention relates to a mounting arrangement of an electrical machine according to the closer defined in the preamble of claim 1. Art.

Aus der Fahrzeugtechnik sind elektrische Maschinen, insbesondere bei Hybridantrieben, bekannt. Üblicherweise sind die elektrischen Maschinen an dem Getriebegehäuse des Fahrzeuges befestigt. Da das Getriebegehäuse und der Stator der elektrischen Maschine aus verschiedenen Werkstoffen gefertigt ist, die unterschiedliche Wärmeausdehnungskoeffizienten aufweisen, entstehen im Bereich der Befestigungen zwischen dem Stator und dem Getriebegehäuse unerwünschte Belastungen z. B. durch Querkräfte entlang der Kontaktflächen.From vehicle technology electrical machines, especially in hybrid drives known. Usually, the electrical machines are attached to the transmission housing of the vehicle. Since the gear housing and the stator of the electric machine is made of different materials, which have different thermal expansion coefficients, arise in the field of fasteners between the stator and the gearbox unwanted loads z. B. by lateral forces along the contact surfaces.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Befestigungsanordnung der eingangs beschriebenen Gattung vorzuschlagen, welche die auftretenden Belastungen aufgrund der unterschiedlichen Wärmeausdehnungskoeffizienten der Werkstoffe zwischen dem Getriebegehäuse und der elektrischen Maschine zu kompensieren.The present invention is based on the object to propose a mounting arrangement of the type described above, which compensate for the loads occurring due to the different thermal expansion coefficients of the materials between the gear housing and the electric machine.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen und den Zeichnungen.This object is achieved by the features of claim 1. Further advantageous embodiments will become apparent from the dependent claims and the drawings.

Demzufolge wird eine Befestigungsanordnung für eine elektrische Maschine in einem Getriebegehäuse eines Fahrzeuges vorgeschlagen, wobei ein Stator der elektrischen Maschine an dem Getriebegehäuse lösbar befestigt ist und zumindest eine verformbare Anbindung oder dergleichen zum Ausgleich von unterschiedlichen Wärmeausdehnungen zwischen dem Getriebegehäuse und dem Stator vorgesehen ist.Accordingly, a mounting arrangement for an electric machine is proposed in a transmission housing of a vehicle, wherein a stator of the electric machine is releasably secured to the transmission housing and at least one deformable connection or the like to compensate for different thermal expansions between the transmission housing and the stator is provided.

Auf diese Weise kann ein zum Beispiel aus Stahl gefertigter Stator der elektrischen Maschine an einem zum Beispiel aus einer Aluminium- oder Magnesium-Legierung gefertigten Getriebegehäuse befestigt werden, ohne dass eine Belastung durch die unterschiedlichen Wärmeausdehnungskoeffizienten der verwendeten Werkstoffe zwischen dem Stator und dem Getriebegehäuse bewirkt wird. Dies wird durch die weiche, verformbare beziehungsweise elastische Anbindung des Statorträgers an dem Getriebegehäuse realisiert. Dadurch kann die Lebensdauer des Stators, des Getriebegehäuses und auch der Befestigung beziehungsweise Anbindung positiv beeinflusst werden.In this way, a stator of the electric machine made of steel, for example, can be fastened to a gearbox made, for example, of an aluminum or magnesium alloy, without causing any stress from the different coefficients of thermal expansion of the materials used between the stator and the gearbox , This is realized by the soft, deformable or elastic connection of the stator carrier to the transmission housing. As a result, the life of the stator, the gear housing and also the attachment or connection can be positively influenced.

Im Rahmen einer besonders vorteilhaften Ausführungsvariante der Erfindung kann vorgesehen sein, dass die weiche, verformbare Anbindung als Befestigungsdom oder dergleichen ausgebildet ist. Somit können die an der Kontaktfläche zwischen dem Stator und dem Getriebegehäuse auftretenden Querkräfte in Folge einer Wärmeausdehnung so gering wie möglich gehalten werden. Vorzugsweise kann der Befestigungsdom an das Getriebegehäuse angeformt, z. B. an gegossen sein und bevorzugt eine längliche Form aufweisen, um entsprechend einfach verformt zu werden. Es sind auch andere konstruktive Ausgestaltungen möglich, um eine entsprechende Verformbarkeit des Befestigungsdoms zum Ausgleich der auftretenden Querkräfte zu gewährleisten.As part of a particularly advantageous embodiment of the invention can be provided that the soft, deformable connection is designed as a mounting dome or the like. Thus, the lateral forces occurring at the contact surface between the stator and the gear housing due to thermal expansion can be kept as low as possible. Preferably, the mounting dome can be integrally formed on the gear housing, z. B. to be cast and preferably have an elongated shape to be easily deformed accordingly. There are also other structural configurations possible to ensure a corresponding deformability of the mounting dome to compensate for the lateral forces occurring.

Wenn zum Befestigen des Stators an dem Getriebegehäuse eine Verschraubung oder dergleichen als lösbare Befestigung verwendet wird, kann zum Beispiel vorgesehen sein, dass jeder Befestigungsdom eine Gewindebohrung für eine Befestigungsschraube aufweist. Es sind aber auch andere lösbare Befestigungsarten denkbar.If a screw or the like is used as a releasable attachment for attaching the stator to the transmission housing, it may be provided, for example, that each attachment dome has a threaded hole for a fastening screw. But there are also other releasable types of attachment conceivable.

Um eine ausreichende Befestigung des Stators an dem Getriebegehäuse zu gewährleisten, kann vorgesehen sein, dass ein Lagerschild des Stators über den Umfang mit mehreren Befestigungsschrauben an zugeordneten Befestigungsdomen des Getriebegehäuses verschraubt wird.In order to ensure a sufficient attachment of the stator to the gear housing, it can be provided that a bearing plate of the stator is screwed over the circumference with a plurality of fastening screws to associated Befestigungsdomen the gear housing.

Vorzugsweise kann der Stator aus Stahl gefertigt sein und das Getriebegehäuse aus einer weicheren, eine höhere Wärmeausdehnung auf weisenden Aluminium- oder Magnesium-Legierung hergestellt sein. Die Befestigungsdome werden aus einem verformbaren z. B. elastischen, relativ weichen Werkstoff gefertigt sein, um eine ausreichende Verformung zum Ausgleich der Querkräfte zu gewährleisten. Bevorzugterweise kann als Werkstoff der Befestigungsdome der gleiche Werkstoff wie für das Getriebegehäuse verwendet werden. Dies hat den Vorteil, dass bei einem aus Guss gefertigten Getriebegehäuse die Befestigungsdome kostengünstig bei der Herstellung angegossen werden. Es sind auch andere Materialien bzw. Werkstoffe für die Befestigungsdome ersetzbar.Preferably, the stator may be made of steel and the gear housing may be made of a softer, higher thermal expansion facing aluminum or magnesium alloy. The attachment domes are made of a deformable z. B. elastic, relatively soft material to ensure sufficient deformation to compensate for the lateral forces. Preferably, the same material as for the transmission housing can be used as the material of the fastening domes. This has the advantage that in a gear housing made of cast iron, the fastening domes are cast inexpensively in the production. There are also other materials or materials for the Befestigungsdome replaceable.

Nachfolgend wird die vorliegende Erfindung anhand der Zeichnungen näher erläutert. Es zeigen:Hereinafter, the present invention will be explained in more detail with reference to the drawings. Show it:

In 1 ist eine mögliche Ausführungsvariante einer Befestigungsanordnung einer elektrischen Maschine 1 in einem Getriebegehäuse 2 beziehungsweise einem Hybridmodul eines nicht weiter dargestellten Hybridantriebes eines Fahrzeuges mit einem Stator 3 dargestellt, der direkt oder indirekt an dem Getriebegehäuse 2 lösbar befestigt sein kann.In 1 is a possible embodiment of a mounting arrangement of an electrical machine 1 in a gearbox 2 or a hybrid module of a not shown hybrid drive of a vehicle with a stator 3 shown directly or indirectly to the transmission housing 2 can be releasably attached.

Der Stator 3 ist über ein Lagerschild 4 an dem Getriebegehäuse 2 befestigt. Dazu sind über den Umfang verteilt an dem Lagerschild 4 mehrere Befestigungsschrauben 5 vorgesehen wie in zugeordneten verformbaren Anbindungen 6 des Getriebegehäuses 2 verschraubt sind.The stator 3 is over a bearing plate 4 on the gearbox 2 attached. These are distributed over the circumference of the bearing plate 4 several fixing screws 5 provided as in associated deformable connections 6 of the gearbox 2 are bolted.

Erfindungsgemäß sind die verformbares Anbindungen 6 zum Ausgleich einer unterschiedlichen Wärmeausdehnung zwischen dem Getriebegehäuse 2 und dem Stator 3 vorgesehen. Wie insbesondere aus 2 ersichtlich ist, sind die verformbaren Anbindungen 6 als Befestigungsdome 7 ausgebildet. Jeder Befestigungsdom 7 ist an das Getriebegehäuse 2 angeformt und weist eine längliche Form auf. Um die Befestigungsschrauben 5 an dem Getriebegehäuse 2 zu befestigen, sind die Befestigungsdome 7 mit einer entsprechenden Gewindebohrung 8 ausgerüstet, in die die Befestigungsschrauben 5 zum Hasten des Lagerschildes 4 des Stators 3 eingeschraubt sind. Bei dieser Ausführung ist das Lagerschild 4 Teil des Stators 3 und direkt mit diesem verbunden. Es ist auch möglich, dass eine indirekte Verbindung vorgesehen ist.According to the invention, the deformable connections 6 to compensate for a different thermal expansion between the transmission housing 2 and the stator 3 intended. As in particular from 2 can be seen, are the deformable connections 6 as a fixing dome 7 educated. Every attachment dome 7 is to the gearbox 2 molded and has an elongated shape. To the fixing screws 5 on the gearbox 2 to fix, are the fixing dome 7 with a corresponding threaded hole 8th equipped, in which the fixing screws 5 to hurry the bearing plate 4 of the stator 3 are screwed in. In this version, the end shield 4 Part of the stator 3 and connected directly to it. It is also possible that an indirect connection is provided.

Dadurch, dass jeder Befestigungsdom 7 aus einem vergleichsweise weichen Werkstoff gefertigt ist, vorzugsweise aus dem gleichen Werkstoff wie das Getriebegehäuse 2, z. B. einer Aluminium- oder Magnesium-Legierung, kann bei einem Temperaturwechsel jeder Befestigungsdom 7 an dem Getriebegehäuse 2 entsprechend verformt werden, um dadurch die Querkraft, die jeweils auf jede Befestigungsschraube 5 wirkt, deutlich zu reduzieren, so dass ein Ausgleich der unterschiedlichen Wärmeausdehnungen der Werkstoffe realisiert wird und die auftretenden Querkräfte kompensiert werden.By doing that every fixing dome 7 is made of a comparatively soft material, preferably of the same material as the transmission housing 2 , z. As an aluminum or magnesium alloy, each mounting dome can at a temperature change 7 on the gearbox 2 be deformed accordingly, thereby increasing the lateral force, each on each fixing screw 5 acts to reduce significantly, so that a balance of the different thermal expansions of the materials is realized and the transverse forces are compensated.
