Durch ein derartiges, so genanntes „Add-On-Konzept" ist es möglich, die Elektromaschine platzsparend gegenüber einer über einen Riemen- oder Kettentrieb in einen Antriebsstrang eingebundenen Elektromaschine in die Antriebsvorrichtung einzugliedern. Der Rotor der Elektromaschine ist dabei mittels eines Rotorlagers drehbar gelagert und mit einer Welle versehen, die mit einer weiteren, sich drehenden Fahrzeugkomponente, wie zum Beispiel dem Getriebe, gekoppelt ist, sodass ein Antriebsdrehmoment von der Elektromaschine über das Getriebe auf Antriebsräder des Fahrzeugs übertragen werden kann.By such an "add-on concept" makes it possible the electric machine saves space over one a belt or chain drive integrated into a drive train Integrate electric machine in the drive device. The rotor The electric machine is rotatable by means of a rotor bearing stored and provided with a shaft, which with another, itself rotating vehicle component, such as the transmission coupled is, so that a drive torque from the electric machine via transmit the transmission to the drive wheels of the vehicle can be.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß ist vorgesehen, dass das Rotorlager ein Festlager ist und dass der Rotor über ein Loslager drehfest auf der Welle gelagert ist. Es ist also vorgesehen, dass das Rotorlager als Festlager ausgebildet ist, welches die Bewegungsfreiheitsgrade des Rotors auf eine Rotations- beziehungsweise Drehbewegung reduziert, sodass der Rotor axial und radial in seiner Position festgelegt ist. Weiterhin ist vorgesehen, dass der Rotor über ein Loslager drehfest auf der Welle gelagert ist. Das Loslager lässt dem Rotor somit einen gewissen Bewegungsfreiraum, sodass die Gesamt-Lagerung des Rotors nicht überbestimmt ist. Das Loslager erlaubt bevorzugt ein Verkippen und/oder ein Verschieben in axialer und/oder radialer Richtung, sodass der Rotor nicht aufgrund von baulichen oder betriebsbedingten Gegebenheiten verspannt und/oder verklemmt. Das Loslager dient hierbei also zweckmäßigerweise als Toleranzausgleich. Aufgrund des Festlagers läuft der Rotor stets in vorgegebener Position, sodass die Elektromaschine besonders effizient betrieben werden kann und ein Verspannen aufgrund des Loslagers verhindert wird. Wobei das Loslager eine drehfeste Verbindung von Rotor und Welle darstellt, sodass über das Loslager lediglich Rotationskräfte beziehungsweise Antriebsmomente übertragen werden. Hierbei spielt es natürlich keine Rolle, ob die Elektromaschine im generatorischen oder im motorischen Betrieb läuft.According to the invention provided that the rotor bearing is a fixed bearing and that the rotor via a Floating bearing is rotatably mounted on the shaft. So it's planned that the rotor bearing is designed as a fixed bearing, which determines the degrees of freedom of movement the rotor is reduced to a rotational movement, so that the rotor is fixed axially and radially in position is. Furthermore, it is provided that the rotor via a Floating bearing is rotatably mounted on the shaft. The floating bearing leaves the Rotor thus a certain freedom of movement, so that the total storage of the rotor is not overdetermined. The floating bearing allowed preferably tilting and / or shifting in the axial and / or radial direction, so that the rotor is not due to structural or operational conditions tense and / or jammed. The floating bearing thus serves this purpose appropriately as tolerance compensation. Due to the fixed bearing, the rotor is running always in a predetermined position, so that the electric machine especially can be operated efficiently and a bracing due to the Loslagers is prevented. Where the floating bearing a non-rotatable connection of rotor and shaft represents, so about the floating bearing only transmit rotational forces or drive torques become. Of course, it does not matter if the electric machine running in regenerative or in motor operation.
Vorteilhafterweise ist der Rotor über das Festlager drehbar an der Elektromaschine gelagert. Das Festlager bildet also zweckmäßigerweise ein Element der Elektromaschine, sodass der Rotor stets in vorgegebener Position zu einem mit dem Rotor zusammenwirkenden Stator beziehungsweise Ständer der Elektromaschine rotiert/läuft. Durch die Lagerung über das Festlager an der Elektromaschine wirkt der Rotor stets, wie bereits gesagt, mit dem Ständer optimal zusammen, wobei er über das Loslager direkt auf der Welle gelagert ist. Die vorteilhafte Anordnung erlaubt eine besonders bauraumsparende Ausbildung der Antriebsvorrichtung, ohne dass Kompromisse in den Betriebseigenschaften der Elektromaschine beziehungsweise der Antriebsvorrichtung eingegangen werden müssen.advantageously, the rotor is rotatable about the fixed bearing on the electric machine stored. The fixed bearing thus forms expediently an element of the electric machine, so that the rotor always in predetermined Position to a cooperating with the rotor stator or Stand of the electric machine rotates / runs. By storage via the fixed bearing on the electric machine The rotor always acts, as already mentioned, with the stand optimally together, being on the floating bearing directly on the shaft is stored. The advantageous arrangement allows a particularly space-saving design of the drive device, without that compromises in the operating characteristics of the electric machine or the drive device must be received.
Besonders bevorzugt ist der Rotor über das Festlager an einem Lagerschild gelagert. Hierbei ist also vorgesehen, dass das Festlager an einem feststehenden Lagerschild angeordnet ist, wobei das Lagerschild ein Teil der Elektromaschine sein kann oder von der Brennkraftmaschine und/oder einer weiteren Komponente der Antriebsvorrichtung, wie zum Beispiel einer Kupplung beziehungsweise eines Kupplungsgehäuses, gebildet wird. Die dynamischen Kräfte des Rotors werden dabei von beiden Lagern der Eigenlagerung der Elektromaschine, also von dem Festlager und dem Loslager aufgenommen. Dies stellt eine Festlagerkombination für den Rotor dar.Especially Preferably, the rotor via the fixed bearing on a bearing plate stored. In this case, it is provided that the fixed bearing on a fixed bearing plate is arranged, wherein the bearing plate may be part of the electric machine or of the internal combustion engine and / or another component of the drive device, such as for example, a clutch or a clutch housing, is formed. The dynamic forces of the rotor become thereby from both camps of the self-storage of the electric machine, ie taken up by the fixed bearing and the floating bearing. This constitutes one Fixed bearing combination for the rotor.
Vorteilhafterweise ist das Lagerschild an einem Gehäuseflansch der Brennkraftmaschine und/oder des Getriebes und/oder der Elektromaschine befestig. Wesentlich dabei ist, dass das Lagerschild und damit der Rotor in Bezug auf den Ständer der Elektromaschine genau ausgerichtet und gelagert ist. Das Lagerschild kann beispielsweise mittels Verschrauben, Verklemmen, Verlöten, Verschweißen und/oder Verkleben an einer der obenstehenden Komponenten der Antriebsvorrichtung befestigt werden.advantageously, is the end shield to a housing flange of the internal combustion engine and / or the gearbox and / or the electric machine fastened. Essential It is that the bearing plate and thus the rotor in relation to The stator of the electric machine accurately aligned and is stored. The bearing plate can be screwed, for example, by screwing, Jamming, soldering, welding and / or gluing attached to one of the above components of the drive device become.
In einer vorteilhaften Ausbildung der Erfindung ist die Welle eine Getriebewelle eines Getriebes der Antriebsvorrichtung und/oder eine Kurbelwelle der Brennkraftmaschine. Der Rotor ist somit direkt auf einer Welle einer der Antriebskomponenten der Antriebsvorrichtung gelagert. Die Elektromaschine selbst weist somit keine eigene Welle auf, die mit den übrigen, rotierenden Antriebsstrangkomponenten gekoppelt ist. Durch die direkte Lagerung des Rotors der Elektromaschine auf einer bereits vorhandenen Welle der Antriebsvorrichtung wird besonders effizient Bauraum gespart, wobei das Loslager, wie bereits oben beschrieben, einen Toleranzausgleich erlaubt. Dieser ist hierbei insbesondere von Bedeutung, da die bereits vorhandenen Wellen, wie zum Beispiel die Getriebewelle, bereits ausreichend gelagert beziehungsweise bestimmt sind. Auch kann die Welle eine Abtriebs- oder Antriebswelle einer Kupplung der Antriebsvorrichtung sein.In an advantageous embodiment of the invention, the shaft is a Transmission shaft of a transmission of the drive device and / or a Crankshaft of the internal combustion engine. The rotor is thus directly on a shaft of one of the drive components of the drive device stored. The electric machine itself thus has no own wave on top of that with the remaining, rotating powertrain components is coupled. Due to the direct storage of the rotor of the electric machine on an already existing shaft of the drive device particularly efficient space savings, with the floating bearing, as already described above, a tolerance compensation allowed. This one is here particularly important, since the already existing waves, such as For example, the transmission shaft, already sufficiently stored or are determined. Also, the shaft can be an output or drive shaft be a clutch of the drive device.
Zweckmäßigerweise weist der Rotor eine die Welle aufnehmende Nabe auf, wobei die Nabe und die Welle zumindest im Bereich der Nabe derart ausgebildet sind, dass sie zusammen das Loslager bilden.Conveniently, the rotor has a shaft receiving hub, wherein the hub and the shaft are formed at least in the region of the hub, that together they form the floating camp.
Bevorzugt ist das Festlager – in axialer Richtung gesehen – im Wesentlichen mittig zu dem Rotor beziehungsweise der Elektromaschine auf der Nabe angeordnet. Auf der Innenseite bildet die Nabe also zusammen mit der Welle das Loslager und auf der Außenseite ist das Festlager angeordnet. Vorteilhafterweise sind Rotor und/oder Nabe derart entsprechend geformt, dass die mittige Anordnung des Festlagers in Bezug auf den Rotor möglich ist. Dadurch ist der Rotor im Wesentlichen in seinem Schwerpunkt drehbar mittels des Festlagers gelagert und auch dort axial sowie radial festgelegt. Dies wirkt sich günstig auf die Rotationseigenschaften des Rotors in jedem Betriebszustand aus.Prefers is the fixed bearing - seen in the axial direction - in Essentially centered to the rotor or the electric machine arranged on the hub. On the inside, the hub thus forms together with the shaft the floating bearing and on the outside that is Fixed bearing arranged. Advantageously, rotor and / or hub shaped in such a way that the central arrangement of the fixed bearing in relation to the rotor is possible. This is the rotor essentially rotatable in its center of gravity by means of the fixed bearing stored and also fixed there axially and radially. This works favorable to the rotational properties of the rotor in any operating condition.
Nach einer Weiterbildung der Erfindung ist das Festlager mindestens ein Wälzlager, insbesondere ein Rillenkugellager. Es ist also vorgesehen, dass das Festlager von einem oder mehreren Wälzlagern/Rillenkugellagern gebildet wird. Dabei liegt das Wälzlager bevorzugt mit seinem Innenring auf der Außenseite der Nabe auf. Die Nabe weist dazu vorteilhafterweise eine Lageraufnahme auf, die einen Axialanschlag bildet, an den das Wälzlager beziehungsweise der Innenring des Wälzlagers geschoben ist. In die andere (axiale) Richtung ist das Wälzlager vorteilhafterweise mittels eines Sicherungsrings beziehungsweise eines Spannrings, der in einer randoffenen, sich über den gesamten Umfang der Nabe erstreckenden Nut einliegt, an einer axialen Bewegung beziehungsweise Verschiebung gehindert. Die Lageraufnahme ist dabei im Wesentlichen mittig zu dem Rotor auf der Nabe angeordnet. Zweckmäßigerweise ist auf ähnliche Art und Weise ein Außenring des Wälzlagers an dem Lagerschild festgelegt. Das Lagerschild ragt dabei zumindest bereichsweise – in axialer Richtung gesehen – in den Rotor hinein, wobei eine besonders kompakte Bauform der Antriebsvorrichtung entsteht.To a development of the invention, the fixed bearing is at least one Rolling, in particular a deep groove ball bearing. So it is provided that the fixed bearing of one or more bearings / deep groove ball bearings is formed. In this case, the rolling bearing is preferred with its inner ring on the outside of the hub. The hub For this purpose, advantageously has a bearing receiving, which is an axial stop forms, to which the rolling bearing or the inner ring the rolling bearing is pushed. In the other (axial) direction the rolling bearing is advantageously by means of a locking ring or a clamping ring in an open-edge, over the entire circumference of the hub extending groove rests on a prevented axial movement or displacement. The camp recording is arranged substantially centrally of the rotor on the hub. Conveniently, is in a similar manner an outer ring of the Rolling bearing fixed to the bearing plate. The bearing plate protrudes at least partially - in the axial direction seen - in the rotor inside, with a particularly compact Design of the drive device arises.
Weiterhin ist vorgesehen, dass das Loslager von einer Verzahnung gebildet ist. Die Verzahnung ist dabei also derart ausgebildet, dass sie der Lagerung des Rotors auf der Welle Loslagereigenschaften gibt. Hierbei weist der Rotor bevorzugt eine Innenverzahnung und die Welle eine Außenverzahnung auf, die ineinandergreifen, wobei die Innenverzahnung zweckmäßigerweise an der Nabe angeordnet ist. Vorteilhafterweise erstreckt sich die Innenverzahnung über die gesamte axiale Länge der Nabe. Bevorzugt erstreckt sich die Außenverzahnung der Welle – in axialer Richtung gesehen – über einen weiteren Bereich als die Innenverzahnung, sodass die Nabe auf der Welle zumindest axial verschieblich ist, wobei stets das gleiche Drehmoment-Übertragungsverhalten gewährleistet ist. Die Innenverzahnung und die Außenverzahnung sind darüber hinaus vorteilhafterweise derart ausgebildet, dass der zuvor erwähnte Toleranzausgleich gewährleistet ist. Dabei sind Innenverzahnung und Außenverzahnung derart ausgebildet, dass zum Beispiel ein Verkippen der Welle in der Nabe möglich ist, ohne dass der Rotor mit radialen (Kipp-)Kräften von der Welle beaufschlagt ist. Die Verzahnung ist derart ausgebildet, dass lediglich eine Drehmomentübertragung zwischen Welle und Rotor beziehungsweise Welle und Nabe stattfindet. Hierdurch werden auch Toleranzen aufgrund von auftretenden temperaturbedingten Längen- und/oder Lageänderungen wirkungsvoll ausgeglichen. Alternativ zu der Verzahnung ist auch jede andere ein Loslager bildende Welle-Nabe-Verbindung denkbar, wie zum Beispiel ein Kegelspannsatz, mindestens eine Passfeder, eine Keilwelle, ein Polygonprofil von Welle und/oder Nabe und/oder mindestens ein Spannelement, das zumindest einen Bewegungsfreiheitsgrad zulässt.Farther is provided that the floating bearing formed by a toothing is. The toothing is thus designed such that they The bearing of the rotor on the shaft gives bearing characteristics. in this connection The rotor preferably has an internal toothing and the shaft has a External teeth on which engage, the internal teeth expediently is arranged on the hub. Advantageously, the extends Internal toothing over the entire axial length the hub. Preferably, the outer toothing extends the shaft - seen in the axial direction - over another area than the internal teeth, so the hub is at least axially displaceable on the shaft, wherein always the ensures the same torque transmission characteristics is. The internal teeth and the external teeth are above Moreover, advantageously designed such that the aforementioned tolerance compensation is guaranteed. Here are internal teeth and external teeth formed such that, for example, a tilting of the shaft in the Hub is possible without the rotor with radial (tilting) forces is acted upon by the shaft. The toothing is designed in such a way that only a torque transmission between shaft and rotor or shaft and hub takes place. hereby are also tolerances due to occurring temperature Length and / or position changes effectively balanced. As an alternative to the gearing, each other is also a movable bearing Shaft-hub connection conceivable, such as a cone clamping set, at least one key, a splined shaft, a polygonal profile of Shaft and / or hub and / or at least one clamping element, at least allows a degree of freedom of movement.
