Derartige
Radnabenantriebe sind bereits aus dem Stand der Technik als bekannt
zu entnehmen. Die Druckschrift
Der
Erfindung liegt die Aufgabe zugrunde, den aus der Druckschrift
Diese Aufgabe wird erfindungsgemäß durch einen Radnabenantrieb mit den Merkmalen gemäß Patentanspruch 1 sowie durch einen Kraftwagen mit den Merkmalen nach Patentanspruch 7 gelöst.These Object is achieved by a wheel hub drive with the features according to claim 1 and also solved by a motor vehicle with the features of claim 7.
Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Embodiments with expedient developments The invention are specified in the subclaims.
Ein erfindungsgemäßer Radnabenantrieb für einen Kraftwagen umfasst einen karosserieseitig angeordneten Antriebsteil sowie einen radnabenseitigen Antriebsteil, welcher einen Winkeltrieb zum Antreiben einer Radnabe umfasst, welche von einem Nabenträger gehalten ist. Ein wesentlicher Gedanke besteht hierbei darin, dass ein Getriebeelement eines Lenkgetriebes an dem Nabenträger angeordnet ist.One inventive hub drive for a Motor vehicle includes a body side arranged drive part and a wheel hub side drive part, which has an angle drive for driving a wheel hub comprising a hub carrier is held. An essential idea here is that a transmission element of a steering gear on the hub carrier is arranged.
Mit anderen Worten besteht ein Grundgedanke der vorliegenden Erfindung darin, den bekannten Radnabenantrieb derart weiterzuentwickeln, dass der Nabenträger mit einem Getriebeelement eines Lenkgetriebes eines Lenksystems des Kraftwagens drehfest verbunden ist. Hierdurch wird in vorteilhafter Weise eine Funktionsintegration und eine kompakte Bauweise des Radnabenantriebs erzielt.With In other words, a basic idea of the present invention It is to develop the known wheel hub drive such that the hub carrier with a transmission element of a steering gear a steering system of the motor vehicle is rotatably connected. hereby is advantageously a functional integration and a compact Construction of the wheel hub drive achieved.
In einer Ausführungsform kann vorgesehen sein, dass der Winkeltrieb innerhalb des Nabenträgers aufgenommen ist. Insbesondere ist bei dieser Ausführungsform vorgesehen, dass der Nabenträger in Form eines Gehäuses ausgestaltet ist, wobei in einem im Nabenträger ausgebildeten Innenraum der Winkeltrieb angeordnet werden kann.In an embodiment may be provided that the angle drive is received within the hub carrier. Especially is provided in this embodiment that the hub carrier in Formed a housing, wherein in a in Hub carrier trained interior of the angle drive arranged can be.
In bevorzugter Weise ist das Getriebeelement des Lenkgetriebes in Form eines drehfest mit dem Nabenträger verbundenen Getrieberades ausgebildet, wobei das Lenkgetriebe bevorzugt als Schneckengetriebe ausgebildet ist. Dabei kann ferner vorgesehen sein, dass das Getriebeelement mit einer Schnecke in Eingriff steht, welche von einer elektrischen Maschine anzutreiben ist. Wird die Schnecke von Seiten der elektrischen Maschine angetrieben, so wird über das Getriebeelement eine Lenkrichtungsänderung des Nabenträgers und somit der Radnabe und eines mit der Radnabe verbundenen Rades erzielt. Durch Einsatz eines Schneckenbetriebes wird in vorteilhafter Weise eine feine Auflösung der Lenkrichtung der Radnabe erzielt, so dass die elektrische Maschine mit einer relativ hohen Drehzahl ausgelegt werden kann.In Preferably, the transmission element of the steering gear is in shape a rotatably connected to the hub carrier gear formed, wherein the steering gear preferably as a worm gear is trained. It can also be provided that the transmission element engaged with a worm, which is of an electric To drive machine is. Will the screw from the side of the electric Machine is powered, so will about the transmission element a steering direction change of the hub carrier and thus achieved the wheel hub and a wheel hub connected to the wheel. By using a screw operation is in an advantageous manner achieves a fine resolution of the steering direction of the wheel hub, so that the electric machine with a relatively high speed can be designed.
In bevorzugter Weise kann der Winkeltrieb zwei Kegelräder umfassen, welche zueinander gewinkelt angeordnet sind und miteinander in Eingriff stehen. Insbesondere sind die Kegelräder in einem rechten Winkel zueinander angeordnet, wobei alternativ vorgesehen sein kann, dass die Kegelräder in einem Winkel kleiner 90° zueinander angeordnet sind. Weiterhin hat sich als vorteilhaft herausgestellt, dass zwischen dem karosserieseitig angeordneten Antriebsteil und dem radnabenseitigen Antriebsteil eine Kupplung vorgesehen ist, welcher eine weitere elektrische Maschine und ein Getriebe vorgeordnet sind. Durch Einsatz des Winkeltriebs einschließlich zweier Kegelräder sowie durch Einsatz der Kupplung, welche vorzugsweise als Torsionskupplung bzw. eine Kupplung mit Längenkompensation ausgebildet ist, wird in vorteilhafter Weise erreicht, dass der karosserieseitig angeordnete Antriebsteil von den ungefederten Maßen des Radnabenantriebs entkoppelt werden kann.In Preferably, the angle drive two bevel gears include, which are arranged angled to each other and each other engage. In particular, the bevel gears are in arranged at right angles to each other, where provided alternatively can be that the bevel gears at an angle smaller Are arranged 90 ° to each other. Furthermore, as advantageously found that between the body side arranged drive part and the hub-side drive part, a clutch is provided, which a further electric machine and a transmission are arranged upstream. By using the angle drive including two bevel gears and by use of the coupling, which preferably as a torsional coupling or a coupling with length compensation is formed is achieved in an advantageous manner that the body side arranged Drive part of the unsprung dimensions of the wheel hub drive can be decoupled.
Ein erfindungsgemäßer Kraftwagen umfasst wenigstens einen erfindungsgemäßen Radnabenantrieb.One Motor vehicle according to the invention comprises at least a wheel hub drive according to the invention.
Bei dem erfindungsgemäßen Kraftwagen kann vorgesehen sein, dass für jedes Rad des Kraftwagens jeweils ein Radnabenantrieb vorgesehen ist. Bei einer modularen Verwendung des Radnabenantriebs bei jedem Rad des Kraftwagens kann in vorteilhafter Weise eine Allradlenkung verwirklicht werden.In the motor vehicle according to the invention it can be provided that a wheel hub drive is provided for each wheel of the motor vehicle. In a modular use of the wheel hub drive in each wheel of the motor vehicle, an all-wheel steering can be realized in an advantageous manner.
