Therefor For example, a pump may be provided which is either mechanically driven is (for example by means of the rotor of the electric machine or by means of a component of the axle differential gear), or the is driven by a separate electric motor.
Vorzugsweise ist jedoch eine pumpenlose Förderung des Fluids vorgesehen. Hierdurch können weitere Bauteile eingespart werden, wodurch sich ein noch einfacherer Aufbau der Achsantriebseinheit ergibt. Insbesondere kann hierfür das Achsdifferentialgetriebe und/oder ein zwischen dem Rotor der elektrischen Maschine und dem Achsdifferentialgetriebe angeordnetes Übersetzungsgetriebe dazu ausgebildet sein, das Fluid zwischen der genannten Getriebe- oder Lagerkomponente und der elektrischen Maschine zu fördern. Beispielsweise kann eine Fluidförderung durch Druckerzeugung durch zwei Getriebeelemente vorgesehen sein, z. B. durch zwei miteinander kämmende Zahnräder, die von einem Druckraum umschlossen sind. In diesem Fall erfolgt ein Verquetschen oder Verspritzen des Fluids aus dem Zahneingriff der jeweiligen Getriebeelemente. Alternativ kann ein Mitführen und Abschleudern des Fluids durch wenigstens ein Getriebeelement vorgesehen sein, z. B. durch ein Zahnrad oder durch einen Rotationskörper mit Schaufeln.Preferably is however a pumpless promotion provided the fluid. As a result, further components can be saved be, resulting in an even simpler structure of the final drive unit results. In particular, this can be done the axle differential and / or between the rotor of the electrical machine and the axle differential gear arranged transmission gear be adapted to the fluid between said transmission or Bearing component and the electric machine to promote. For example can be a fluid delivery be provided by pressure generation by two gear elements, z. B. by two intermeshing Gears, which are enclosed by a pressure chamber. In this case, done a squashing or splashing of the fluid from the tooth engagement the respective transmission elements. Alternatively, a carry and Spinning the fluid provided by at least one transmission element be, z. B. by a gear or by a rotating body with Blades.
