Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft eine Antriebseinheit mit wenigstens einen Hauptmotor sowie einem Stellmotor und mit ein Getriebe, in welcher die Motoren und die Hauptachse des Getriebes koaxial zueinander ausgerichtet sind.The invention relates to a drive unit with at least one main motor and a servomotor and with a transmission in which the motors and the main axis of the transmission are aligned coaxially with each other.
Hintergrund der ErfindungBackground of the invention
Eine derartige Antriebseinheit ist in
Beschreibung der ErfindungDescription of the invention
Die Aufgabe der Erfindung ist es, eine Antriebseinheit zu schaffen, die kompakt ausgebildet ist und dementsprechend wenig Bauraum für sich beansprucht und die sich einfach montieren lässt.The object of the invention is to provide a drive unit which is compact and accordingly requires little space for itself and which can be easily assembled.
Erfindungsgemäß ist vorgesehen, dass die Antriebseinheit wenigstens einen Hauptmotor sowie einen Stellmotor und ein Getriebe aufweist. Die Motoren, sind vorzugsweise Elektromotoren. Die Rotationsachsen der Rotorwellen und die Hauptachse des Getriebes sind koaxial zueinander ausgerichtet. Die Motoren und das Getriebe sind in einem gemeinsamen Gehäuse aufgenommen. Das Getriebe ist wenigstens aus einem Differenzial und aus einer Torque-Vectoring-Einheit gebildet. Das Differenzial ist mit dem Hauptmotor antreibbar und die zwischen das Differenzial und den Stellmotor geschaltet Torque-Vectoring-Einheit ist mit dem Stellmotor antreibbar wirkverbunden. Die gemeinsame Unterbringung der einzelnen Baugruppen in einem Gehäuse ermöglicht eine kompakte und unabhängige Antriebseinheit.According to the invention it is provided that the drive unit has at least one main motor and a servomotor and a transmission. The motors are preferably electric motors. The axes of rotation of the rotor shafts and the main axis of the gear are aligned coaxially with each other. The motors and gearbox are housed in a common housing. The transmission is formed at least of a differential and a torque vectoring unit. The differential is drivable with the main motor and the torque vectoring unit connected between the differential and the servomotor is drivably operatively connected to the servomotor. The common placement of the individual modules in a housing allows a compact and independent drive unit.
Der Begriff Torque-Vectoring-Einheit steht für ein Getriebe, vorzugsweise für ein Planetengetriebe, über das vom Stellmotor aufgebrachte Leistung zusätzlich zum Hauptantrieb in das Differenzial Drehmomente eingebracht werden. Dadurch wird die an sich einem Differenzial natürliche Drehmomentaufteilung auf die Antriebswellen gezielt beeinflusst und überlagert.The term torque vectoring unit stands for a transmission, preferably for a planetary gear, are introduced via the power applied by the servomotor in addition to the main drive in the differential torques. As a result, the torque distribution which is inherently natural to a differential is selectively influenced and superimposed on the drive shafts.
Die Antriebseinheit lässt sich einfach montieren, wenn, wie eine Ausgestaltung der Erfindung vorsieht, zumindest das Differenzial eine unabhängig vom Gehäuse in sich selbst haltende vormontierte Baueinheit ist, die ins Gehäuse oder in ein Gehäuseteil eingesetzt werden kann. Mit einer derartigen Ausbildung ist die Anzahl der Teile an Standort der Endmontage der Antriebseinheit reduziert. Alternativ zu dieser Ausgestaltung der Erfindung oder in Kombination mit dieser Ausgestaltung ist vorgesehen, dass die Torque-Vectoring-Einheit eine unabhängig vom Gehäuse in sich selbst haltende vormontierte Baueinheit ist.The drive unit can be mounted easily if, as an embodiment of the invention provides, at least the differential is an independent of the housing in self-holding preassembled unit that can be used in the housing or in a housing part. With such a design, the number of parts at the location of the final assembly of the drive unit is reduced. As an alternative to this embodiment of the invention, or in combination with this embodiment, it is provided that the torque vectoring unit is a preassembled unit that is self-contained independently of the housing.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Antriebseinheit ein aus wenigstens drei Gehäuseteilen gebildetes Gehäuse aufweist, in der vorzugsweise der Hauptmotor, das Getriebe und der Stellmotor jeweils in einem anderen der Gehäuseteile untergebracht sind.A further embodiment of the invention provides that the drive unit has a housing formed from at least three housing parts, in which preferably the main motor, the gearbox and the servo motor are each housed in another of the housing parts.
Die zuvor und nachstehend beschriebenen Elemente der Erfindung machen es möglich, Antriebseinheiten nach dem Baukastenprinzip zusammenzusetzen, die unterschiedlichen Anforderungen angepasst sind. Die Vielzahl der Einzelteile kann durch die Wahl von Gleichteilen und/oder durch das wahlweise Kombinieren von vormontierten Baugruppen reduziert werden.The above and below described elements of the invention make it possible to assemble drive units according to the modular principle, which are adapted to different requirements. The plurality of parts can be reduced by the choice of common parts and / or by the optional combination of pre-assembled modules.
