Description
Die Erfindung betrifft ein Antriebselement eines Getriebes für einen Hybrid-Antriebsstrang, nach dem Oberbegriff des Patentanspruchs 1. The invention relates to a drive element of a transmission for a hybrid drive train, according to the preamble of patent claim 1.

Um einen guten Wirkungsgrad der elektrischen Maschine zu erzielen, ist es bekanntlich notwendig, den Luftspalt zwischen Rotor und Stator der E-Maschine sehr klein und gleichmäßig zu halten. Auch wachsen Radialkräfte bei einer Deachsierung des Rotors zum Stator – also bei einem Schiefstand und/oder Parallelversatz zwischen den Mittelachsen von Rotor und Stator – drastisch an, wenn der Rotor wie bei Synchronmaschinen üblich mit Permanentmagneten bestückt ist. Lagerbelastungen und Unwuchtkräfte nehmen mit der Deachsierung zu, zudem werden dadurch Schwingungen und Geräusche erzeugt. Für die Lagerung des Rotors relativ zum Stator bedeutet dies, dass der Rotor möglichst nahe dem Stator gelagert sein sollte, mit einer kurzen Toleranzkette über möglichst wenige Bauteile relativ zum Stator. In order to achieve a good efficiency of the electric machine, it is known to be necessary to keep the air gap between the rotor and the stator of the electric motor very small and uniform. Radial forces also increase dramatically when the rotor is deactivated to the stator-that is to say when there is an oblique position and / or a parallel offset between the center axes of the rotor and stator-if the rotor is equipped with permanent magnets, as is the case with synchronous machines. Bearing loads and imbalance forces increase with the Deachsierung, it also generates vibrations and noises. For the bearing of the rotor relative to the stator, this means that the rotor should be mounted as close as possible to the stator, with a short tolerance chain over as few components as possible relative to the stator.
Zur Lagerung der beiden E-Maschinen-Rotoren und der drehmomentführenden Wellen ihres Antriebselementes schlägt die
Die erste E-Maschine ist in einem eigenen ringförmigen Gehäuse angeordnet, das axial zwischen dem Verbrennungsmotorgehäuse und der Glocke des Getriebegehäuses eingeschraubt ist. Der Stator der ersten E-Maschine ist in diesem ringförmigen Gehäuse radial zentriert und eingeschraubt. Der Rotor der ersten E-Maschine ist jeweils mit der Kurbelwelle des Verbrennungsmotors und dem Eingangselement des Drehschwingungsdämpfers verschraubt. Die Ausgangsseite des Drehschwingungsdämpfers ist über eine Mitnahmeverzahnung formschlüssig mit der Nabe des Innenlamellenträgers der Trennkupplung verbunden. The first electric machine is arranged in a separate annular housing, which is screwed axially between the engine housing and the bell of the gear housing. The stator of the first electric machine is radially centered and screwed in this annular housing. The rotor of the first electric motor is bolted to the crankshaft of the internal combustion engine and the input element of the torsional vibration damper. The output side of the torsional vibration damper is positively connected via a driving toothing with the hub of the inner disk carrier of the separating clutch.

Derartige Fluchtungsfehler sind in nachteiliger Weise obligatorisch, einerseits aufgrund der konstruktiv vordefinierten eigenen Form- und Lagetoleranzen aller an der Drehmomentübertragung beteiligten Komponenten, und andererseits aufgrund der konstruktiv vordefinierten Form- und Lagetoleranzen in der Kette aller an der Abstützung dieser drehmomentführenden Komponenten beteiligten Bauteile. Such misalignments are disadvantageously obligatory, on the one hand due to the structurally predefined own shape and position tolerances of all involved in the torque transfer components, and on the other hand due to the structurally predefined shape and position tolerances in the chain of all participating in the support of these components leading torque components.
Der Erfindung liegt die Aufgabe zugrunde, ausgehend von dem aus der
Erfindungsgemäß gelöst wird diese Aufgabe durch ein Antriebselement mit den Merkmalen des Patentanspruchs 1. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen. This object is achieved according to the invention by a drive element having the features of patent claim 1. Further advantageous embodiments of the invention emerge from the subclaims.
Demnach wird ein Antriebselement eines Getriebes für einen Hybrid-Antriebsstrang vorgeschlagen, welches innerhalb einer Glocke eines Getriebegehäuses des Getriebes angeordnet ist und folgende Bauteile aufweist: eine Antriebswelle, die durch eine Kurbelwelle einer Verbrennungskraftmaschine des Hybrid-Antriebsstrangs antreibbar ist, eine Kupplung zum Verbinden der Antriebswelle mit einer Eingangswelle des Getriebes, eine E-Maschine zum Antreiben der Eingangswelle des Getriebes, sowie ein in der Glocke des Getriebegehäuses radial zentrierten Lagerschild zum öl- bzw. schmutzdichten Abschließen der Glocke zur Verbrennungskraftmaschine hin. Dabei ist die Antriebswelle über eine erste Lagerstelle radial an dem Lagerschild gelagert, ein Eingangselement der Kupplung mit der Antriebswelle verdrehfest verbunden oder drehelastisch wirkverbunden, ein Stator der E-Maschine in der Glocke des Getriebegehäuses radial zentriert und mit dem Getriebegehäuse verdrehfest verbunden, ein Rotor der E-Maschine verdrehfest mit einem Ausgangselement der Kupplung und verdrehfest mit einer Rotornabe verbunden, die Rotornabe über eine zweite Lagerstelle radial an dem Getriebegehäuse gelagert und die Getriebeeingangswelle über eine dritte Lagerstelle radial an dem Getriebegehäuse gelagert. Die Rotornabe kann zudem radial an der Antriebswelle gelagert sein. Accordingly, a drive element of a transmission for a hybrid drive train is proposed, which is arranged within a bell of a transmission housing of the transmission and comprising the following components: a drive shaft which is drivable by a crankshaft of an internal combustion engine of the hybrid drive train, a clutch for connecting the drive shaft with an input shaft of the transmission, an electric motor for driving the input shaft of the transmission, as well as a radially centered in the bell of the gear housing bearing plate for oil or dirt-tight closing the bell to the internal combustion engine. In this case, the drive shaft via a first bearing radially mounted on the bearing plate, an input element of the clutch to the drive shaft rotationally connected or torsionally operatively connected, a stator of the electric motor in the bell of the gear housing radially centered and rotationally connected to the transmission housing, a rotor of E-machine rotationally connected to an output element of the clutch and rotationally connected to a rotor hub, the rotor hub radially mounted on a second bearing point on the transmission housing and the transmission input shaft via a third bearing radially mounted on the transmission housing. The rotor hub can also be mounted radially on the drive shaft.
Erfindungsgemäß ist die Rotornabe über eine separate Verbindungswelle mit der Getriebeeingangswelle verbunden, wobei die Verbindungswelle über eine erste Mitnahmeverzahnung formschlüssig mit der Rotornabe und über eine zweite Mitnahmeverzahnung formschlüssig mit der Getriebeeingangswelle verbunden ist. According to the invention, the rotor hub is connected via a separate connecting shaft to the transmission input shaft, wherein the connecting shaft is positively connected via a first driving toothing with the rotor hub and a second driving toothing form-fitting manner with the transmission input shaft.
Eine direkte Verbindung zwischen Rotornabe und Getriebeeingangswelle über nur eine formschlüssige Steckverzahnung – so wie im Stand der Technik der
Erst durch das Vorsehen dieser separaten Verbindungswelle im Kraftfluss zwischen der ständig mit dem Rotor der E-Maschine und ständig mit dem Ausgangselement der Kupplung verbundenen Rotornabe und der Getriebeeingangswelle ist ein Ausgleich von zwischen den Rotationsachsen von Antriebswelle und Getriebeeingangswelle obligatorisch auftretenden Fluchtungsfehlern in verblüffend einfacher Weise möglich. Die Verbindungswelle fungiert hier nämlich als eine Art Zahnkupplung. Zwar ist durch die bereits erwähnte Zentrierwirkung von Steckverzahnungsverbindungen unter Drehmoment ein direkter Ausgleich der Fluchtungsfehler nicht möglich, jedoch kann die zwischen Rotornabe und Getriebeeingangswelle eingesteckte Verbindungswelle in ihren beiden Mitnahmeverzahnungen in einem definierten geringen Maß verkippen. Dies wiederum führt zu einem kardanischen Effekt bei jeder Drehung der Verbindungswelle, der zum Ausgleich der Fluchtungsfehler erfindungsgemäß genutzt wird. Only by providing this separate connecting shaft in the power flow between the rotor hub of the electric motor and constantly connected to the output element of the clutch rotor hub and the transmission input shaft compensation of mandatory between the axes of rotation of the drive shaft and transmission input shaft alignment errors in a surprisingly simple manner possible , The connecting shaft acts here as a kind of gear coupling. Although a direct compensation of misalignment is not possible by the already mentioned centering of splined connections under torque, however, the inserted between the rotor hub and transmission input shaft connecting shaft can tilt in their two driving teeth in a defined small measure. This in turn leads to a gimbal effect with each rotation of the connecting shaft, which is used according to the invention to compensate for misalignment.
In einer bevorzugten Ausgestaltung der Erfindung sind die Zahnflanken der ersten und zweiten Mitnahmeverzahnung in Längsrichtung gesehen ballig ausgeführt. Hierdurch ergibt sich in vorteilhafter Weise eine Vergrößerung des möglichen Kippwinkels der Verbindungswelle relativ zur Rotornabe und relativ zur Getriebeeingangswelle. In a preferred embodiment of the invention, the tooth flanks of the first and second driving teeth are designed to be spherical in the longitudinal direction. This results in an advantageous manner an increase in the possible tilt angle of the connecting shaft relative to the rotor hub and relative to the transmission input shaft.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Verbindungswelle radial selber nicht gelagert. Auch diese Maßnahme trägt in vorteilhafter Weise dazu bei, dass die kardanische Bewegung der Verbindungswelle beim Drehen nicht behindert wird. In a further advantageous embodiment of the invention, the connecting shaft is not supported radially itself. Also, this measure contributes advantageously to the fact that the gimbal movement of the connecting shaft is not hindered when turning.
In einer Ausgestaltung der Erfindung wird zur räumlichen Anordnung der Verbindungswelle vorgeschlagen, die Verbindungswelle zentrisch vollständig innerhalb der Rotornabe anzuordnen, sodass sich die axiale Baulänge des Antriebselementes trotz des zusätzlichen Bauteils nicht vergrößert. Ein zusätzliches Sicherungselement, durch das die Verbindungswelle axial and der Rotornabe oder axial an der Getriebeeingangswelle fixiert ist, kann hierbei vorgesehen sein. Ein solches Sicherungselement ist aber nicht unbedingt erforderlich, wenn die Verbindungswelle eine erste Anlageschulter, die sich gegen eine korrespondierende Anlageschulter der Rotornabe axial abstützen kann, sowie eine zweite Anlageschulter, die sich gegen eine korrespondierende Anlageschulter der Getriebeeingangswelle axial abstützen kann, aufweist; die Verbindungswelle somit zwischen den genannten Anlageschultern von Rotornabe und Getriebeeingangswelle mit hinreichend großem, konstruktiv vordefiniertem Axialspiel eingesetzt ist. Um die Verkippung der Verbindungswelle relativ zur Rotornabe und Getriebeeingangswelle nicht zu behindern, ist es hierbei vorteilhaft, wenn sowohl der axiale Kontakt zwischen Verbindungswelle und Rotornabe als auch der axiale Kontakt zwischen Verbindungswelle und Getriebeeingangswelle jeweils nicht flächig sondern linienförmig ist. Diese Maßnahme verhindert eine Veränderung der auf die Verbindungswelle wirkenden Rückstellkräfte, die in Abhängigkeit des Verkippwinkels dem Verkippen der Verbindungswelle entgegenstehen. Ein solcher Linienkontakt zwischen der rotornabenseitigen ersten Anlageschulter der Verbindungswelle und der korrespondierenden Anlageschulter der Rotornabe ergibt sich beispielsweise dann, wenn eine dieser beiden axial unmittelbar benachbarten Anlageschultern als Ringwulst ausgebildet ist, während die andere als ebene Kreisringfläche ausgebildet ist. Entsprechend ergibt sich zwischen der getriebeeingangswellenseitigen zweiten Anlageschulter der Verbindungswelle und der korrespondierenden Anlageschulter der Getriebeeingangswelle ein Linienkontakt beispielsweise dann, wenn eine dieser beiden axial unmittelbar benachbarten Anlageschultern als Ringwulst ausgebildet ist, während die andere als ebene Kreisringfläche ausgebildet ist. In one embodiment of the invention, it is proposed for the spatial arrangement of the connecting shaft to arrange the connecting shaft centric completely within the rotor hub, so that the axial length of the drive element does not increase despite the additional component. An additional securing element, by means of which the connecting shaft is fixed axially to the rotor hub or axially to the transmission input shaft, can be provided in this case. However, such a securing element is not absolutely necessary if the connecting shaft has a first abutment shoulder, which can be axially supported against a corresponding abutment shoulder of the rotor hub, and a second abutment shoulder, which can be axially supported against a corresponding abutment shoulder of the transmission input shaft; the connecting shaft is thus inserted between the abovementioned contact shoulders of the rotor hub and the transmission input shaft with a sufficiently large, structurally predefined axial play. In order not to hinder the tilting of the connecting shaft relative to the rotor hub and the transmission input shaft, it is advantageous if both the axial contact between connecting shaft and rotor hub and the axial contact between connecting shaft and transmission input shaft is not flat but linear. This measure prevents a change in the forces acting on the connecting shaft restoring forces that oppose the tilting of the connecting shaft as a function of the tilt angle. Such a line contact between the rotor hub side first abutment shoulder of the connecting shaft and the corresponding contact shoulder of the rotor hub results, for example, if one of these two axially immediately adjacent abutment shoulders is formed as an annular bead, while the other is formed as a flat annular surface. Accordingly arises between the transmission input shaft side second abutment shoulder of the connecting shaft and the corresponding contact shoulder of the transmission input shaft line contact, for example, if one of these two axially immediately adjacent abutment shoulders is formed as an annular bead, while the other is formed as a flat annular surface.
Der besondere technischer Vorteil dieser Ausführung liegt darin, dass der präzise definierbare und prozesssicher herstellbare Anlagedurchmesser der Ringwulst sich trotz möglichem Verschleiß durch kardanische Ausgleichsbewegungen während des Betriebes nicht verändert. Wäre der Anlagebereich beim Verkippen der Verbindungswelle in Form einer Außenkante ausgeführt, so würde sich mit dessen Kantenverschleiß auch der Anlagedurchmesser und somit die Kräfteverhältnisse auf die Verbindungswelle über Getriebelebensdauer verändern. Zudem ist der obligatorische Kantenverschleiß der Ringwulst-Konstruktion über die Lebensdauer gesehen vergleichsweise gering. The particular technical advantage of this design is that the precisely definable and reliably manufactured plant diameter of the annular bead does not change despite possible wear by gimbal compensatory movements during operation. If the contact area when tilting the connecting shaft in the form of an outer edge, so would the plant diameter and thus change the balance of power on the connecting shaft via transmission life with its edge wear. In addition, the mandatory edge wear of the annular bead construction seen over the life comparatively low.
Insbesondere dann, wenn im Kraftfluss zwischen dem Eingangselement der Kupplung und der Antriebswelle ein Torsionsdämpfer zur Isolation von Drehungleichförmigkeiten des Verbrennungskraftmaschine vorgesehen ist, ist es vorteilhaft, das Eingangselement der Kupplung radial an der Rotornabe zu lagern. In particular, when a torsion damper for isolating rotational irregularities of the internal combustion engine is provided in the power flow between the input element of the clutch and the drive shaft, it is advantageous to support the input element of the coupling radially to the rotor hub.
Die Bauart der E-Maschine, die Bauart der Kupplung sowie die Bauart des Getriebes sind im Rahmen der Erfindung beliebig; entsprechend liegt deren Auswahl im Ermessen des Fachmanns, orientiert an den jeweiligen Einsatzbedingungen für das Antriebselement. The design of the electric motor, the design of the clutch and the design of the transmission are arbitrary within the scope of the invention; Accordingly, their selection is at the discretion of the skilled person, based on the particular conditions of use for the drive element.
