Description

Ausgestaltung des Rotors einer elektrischen Maschine eines Hvbridantriebs- strangs eines Kraftfahrzeugs Embodiment of the rotor of an electric machine of a Hvbridantriebs- strand of a motor vehicle
Die vorliegende Erfindung bezieht sich auf die Ausgestaltung des Rotors einer elektrischen Maschine eines Hybridantriebsstrangs eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to the configuration of the rotor of an electric machine of a hybrid drive train of a motor vehicle according to the preamble of patent claim 1.
Aus dem Stand der Technik ist die Notwendigkeit bekannt, bei elektrischen Maschinen Maßnahmen zu ergreifen, die einem sicheren Transport der elektrischen Maschine dienen; hierbei darf der Rotor der elektrischen Maschine den Stator nicht berühren. Des weiteren können Situationen auftreten, bei denen eine drehmomentübertragende Verbindung des Rotors mit einer Zusatzwelle, beispielsweise mit einer Welle am Prüfstand, erforderlich ist, was in der Regel einen Mahraufwand erfordert.From the prior art, the need is known to take measures in electrical machines, which serve for a safe transport of the electrical machine; In this case, the rotor of the electric machine must not touch the stator. Furthermore, situations may arise in which a torque transmitting connection of the rotor with an additional shaft, for example with a shaft on the test bench, is required, which usually requires a Mahraufwand.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ausgestaltung des Rotors einer elektrischen Maschine eines Hybridantriebsstrangs eines Kraftfahrzeugs anzugeben, welche zur Transportsicherung und zum Anflanschen zusätzlicher Wellen geeignet ist. Zudem soll die Ausgestaltung des Rotors eine weitreichende Flexibilität bei der Ausgestaltung des Hybridmoduls gewährleisten.The present invention has for its object to provide an embodiment of the rotor of an electric machine of a hybrid powertrain of a motor vehicle, which is suitable for securing transport and for flanging additional waves. In addition, the design of the rotor to ensure a far-reaching flexibility in the design of the hybrid module.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.This object is solved by the features of patent claim 1. Further embodiments and advantages of the invention will become apparent from the dependent claims.
Demnach wird ein Rotor einer elektrischen Maschine vorgeschlagen, dessen Nabe mit einem Lagerflansch ausgeführt ist, welcher mehrere radial angeordnete Durchgangsbohrungen mit Gewinde und einen Zentriersitz um- fasst. Hierbei ist gemäß einer vorteilhaften Ausführungsform der Erfindung die dem Flansch gegenüberliegende Abdeckung im Durchmesserbereich der Durchgangsbohrungen eben ausgeführt, wodurch für den Transport der elektrischen Maschine Stützschrauben zur Abstützung und Fixierung des Rotors gegenüber dem Stator verwendet werden können.Accordingly, a rotor of an electrical machine is proposed, whose hub is designed with a bearing flange, which surrounds a plurality of radially arranged threaded through-holes and a centering. Here, according to an advantageous embodiment of the invention, the flange opposite cover in the diameter range of the through holes made flat, which can be used for the transport of the electric machine support screws for supporting and fixing the rotor relative to the stator.
Auf diese Weise wird vermieden, dass der Rotor mit dem Stator in Berührung kommt. Des weiteren wird in vorteilhafter Weise das Rotorlager durch die Stützschrauben entlastet; ohne die Stützschrauben würde auf das Rotorlager das Gesamtgewicht des Rotors sowie bei Erschütterungen ein Mehrfaches davon wirken.In this way it is avoided that the rotor comes into contact with the stator. Furthermore, the rotor bearing is relieved by the support screws in an advantageous manner; without the support bolts, the total weight of the rotor would act on the rotor bearing as well as multiples of it in shocks.
Die erfindungsgemäße Ausgestaltung der Rotornabe ermöglicht das Anflanschen einer Zusatzwelle, was beispielsweise am Prüfstand erforderlich sein kann. Hierbei dient der Zentriersitz der fluchtenden Ausrichtung der Zusatzwelle, beispielsweise einer Prüfstandwelle, wobei die Übertragung des Drehmoments durch eine Verschraubung ermöglicht wird.The inventive design of the rotor hub allows flanging a supplementary shaft, which may be required, for example, on the test bench. Here, the centering seat of the aligned alignment of the additional shaft, for example, a test stand shaft, wherein the transmission of the torque is made possible by a screw.

Vorzugsweise sind die Rotomabe und die Kupplung ineinander verschachtelt angeordnet. Im Rahmen einer Weiterbildung der Erfindung kann auch eine Hybridmodulvariante ohne Vorübersetzung der elektrischen Maschine realisiert werden. Hierbei wird die Variante mit Vorübersetzung dahingehend modifiziert, dass die Planeten am Planetenträger entfallen, wobei ein mit dem Rotor verbundener Mitnehmerring vorgesehen ist, der mit dem Außenlameüenträger der Kupplung und somit mit dem Planetenträger verbunden ist.For this purpose, the Rotomabe is designed as a ring gear of a planetary gear and drives the planet carrier of the planetary gear, which is connected on the one hand to the transmission input and on the other hand with the outer disk carrier of a clutch whose inner disk carrier is connected to the drive shaft of the internal combustion engine, wherein the sun gear of the Planetary gear is fixed. Preferably, the Rotomabe and the coupling are arranged nested. Within the scope of a development of the invention, a hybrid module variant without pretranslation of the electrical machine can also be realized. Here, the variant is modified with pretranslation to the effect that the planet accounts for the planet carrier, wherein a driver ring connected to the rotor is provided, which is connected to the Außenlameüenträger the clutch and thus to the planet carrier.
Hierbei wird gemäß der Erfindung der Mitnehmerring an den bestehenden Lagerflansch angebunden; die Innenkontur des Mitnehmerrings ist derart ausgeführt, dass dieser in den Außenlamellenträger der Kupplung eingreift. Auf diese Weise wird die Verzahnung des Außenlamellenträgers als Mitnahmeverzahnung genutzt und zur Drehmomentübertragung von der elektrischen Maschine zum Getriebeeingang verwendet.Here, according to the invention, the driving ring is connected to the existing bearing flange; the inner contour of the driver ring is designed such that it engages in the outer disk carrier of the clutch.
