Abstract
Description
Die Erfindung betrifft einen Radantrieb mit einem Abtriebsrotor, einem vorgeschalteten Planetengetriebe, das eine erste und eine zweite Planetenstufe aufweist, und einer Bremse, wobei ein Steg der zweiten Planetenstufe mit dem Abtriebsrotor verbunden ist.The invention relates to a wheel drive with an output rotor, an upstream planetary gear, which has a first and a second planetary stage, and one Brake, a web of the second planetary stage with the output rotor connected is.
Ein gattungsgemäßer Radantrieb ist aus der
Demnach handelt es sich bei der Bremse des aus dem Stand der Technik bekannten Radantriebs weder um eine langsam laufende Bremse, deren Drehzahl gleich der Drehzahl des Abtriebsrotors ist, noch um eine schnell laufende Bremse, die mit dem Eingangselement der ersten Planetenstufe des Planetengetriebes gekoppelt ist. Die Bremse des gattungsgemäßen Radantriebs weist gegenüber einer schnell laufenden Bremse geringere Verluste auf. Gegenüber einer langsam laufenden Bremse ist das Bremsmoment geringer. Nachteilig ist jedoch, dass das Bremsmoment stets über die spielbehaftete zweite Planetenstufe übertragen werden muss. Ferner führt die Anordnung der Bremse zwischen den beiden Planetenstufen zu einer Vergrößerung des für das Planetengetriebe benötigten Bauraums, insbesondere in axialer Richtung.Accordingly, it is the brake of the Known from the prior art wheel drive neither slow running brake, the speed of which is equal to the speed of the output rotor, still a fast-running brake with the input element the first planetary stage of the planetary gear is coupled. The Brake of the generic wheel drive points to a high-speed brake has lower losses. Opposite one slow-running brake, the braking torque is lower. adversely is, however, that the braking torque is always above the backlash second Transfer planetary stage must become. Furthermore leads the arrangement of the brake between the two planetary stages to one Enlargement of the for the Planetary gear needed Installation space, especially in the axial direction.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen kompakten Radantrieb der eingangs genannten Art zur Verfügung zu stellen, der verringerte Verluste und weniger Verschleiss aufweist.The present invention lies the task is based on a compact wheel drive of the aforementioned Kind available to provide reduced losses and less wear.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Bremse im wesentlichen innerhalb des axialen Bauraums des Planetengetriebes radial über der ersten Planetenstufe und axial benachbart zur zweiten Planetenstufe angeordnet ist und einen mit dem Steg der zweiten Planetenstufe verbundenen Bremsrotorträger aufweist.This object is achieved according to the invention solved, that the brake is essentially within the axial space of the Planetary gear radially over the first planetary stage and axially adjacent to the second planetary stage is arranged and one connected to the web of the second planetary stage Brake rotor carrier having.
Der erfindungswesentliche Gedanke besteht demnach darin, durch Verbindung des Bremsrotorträgers mit dem als Abtrieb dienenden Steg der zweiten Planetenstufe eine langsam laufende Bremse zu schaffen, die nur geringe Verluste hat, und diese Bremse im Bereich des Planetengetriebes so anzuordnen, dass durch geschickte Ausnutzung des zur Verfügung stehenden Bauraums der Platzbedarf für die Bremse minimiert wird. Gegenüber einem zweistufigen Planetengetriebe ohne Bremse wird dabei der Bauraum – insbesondere in axialer Richtung – praktisch nicht oder nur unwesentlich vergrößert.The idea essential to the invention therefore consists in connecting the brake rotor support with the web of the second planetary stage serving as downforce is a slow one to create running brake that has little loss, and this brake to be arranged in the area of the planetary gear so that by skillful Exploitation of the available the space required for the brake is minimized. Across from A two-stage planetary gear without brake is the installation space - in particular in the axial direction - practical not enlarged or only slightly enlarged.
Als Bremsrotor im Sinne der Erfindung kommen sowohl die rotierenden Bremslamellen einer Lamellenbremse als auch die Scheibe(n) einer Scheibenbremse in Frage.As a brake rotor in the sense of the invention come both the rotating brake discs of a multi-disc brake as well as the disc (s) of a disc brake in question.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist der Bremsrotorträger einen Flanschbereich mit dem Steg zugewandten Axialausnehmungen auf, in die die Stegzapfen des Stegs eintauchen und stirnseitig mit dem Bremsscheibenträger verschraubt sind. Diese Bauweise ist sowohl raumsparend als auch sicher im Hinblick auf die Bremsmoment übertragende Verbindung zwischen dem Bremsrotorträger und dem Steg.According to an advantageous embodiment According to the invention, the brake rotor support has a flange area on the web facing axial recesses into which the web pins Immerse the bar and screw it onto the front of the brake disc carrier are. This design is both space-saving and safe in terms of transferring to the braking torque Connection between the brake rotor support and the bridge.
In Weiterbildung der Erfindung wird vorgeschlagen, dass der Abtriebsrotor als Radwelle ausgebildet ist, die in einem lösbar an einem Achsrohr befestigten Radkopf-Gehäuse gelagert ist, wobei die Bremse und zumindest die erste Planetenstufe des Planetengetriebes im Achsrohr angeordnet sind. Eine derartige Anordnung ermöglicht einen geringen Durchmesser im Bereich der Lagerung der Radwelle.In further development of the invention proposed that the output rotor be designed as a wheel shaft, the solvable in one wheel head housing attached to an axle tube is mounted, the brake and at least the first planetary stage of the planetary gear are arranged in the axle tube. Such one Arrangement allows a small diameter in the area of the wheel shaft bearing.
Am Außende der Radwelle ist mit Vorteil ein zur Befestigung eines Rades ausgebildeter Flansch angeformt. Der Fertigungs- und Montageaufwand für die Radwelle wird dadurch klein gehalten.On the outside of the wheel shaft is with Advantage molded on a flange designed for fastening a wheel. The manufacturing and assembly effort for the wheel shaft is thereby kept small.
Zweckmäßigerweise ist am Innenende der Radwelle der Steg der zweiten Planetenstufe mittels einer Keil- oder Kerbverzahnung befestigt. Selbstverständlich können aber auch andere geeignete Welle-Nabe-Verbindungen verwendet werden.Convenient is at the inside end the wheel shaft of the web of the second planetary stage by means of a wedge or serration attached. Of course, other suitable ones can also be used Shaft-hub connections are used.
Besonders günstig ist es, wenn die Bremse einen Bremskolben aufweist, der axial vor der ersten Planetenstufe angeordnet ist. Es ist hierbei möglich, trotz kompakter Abmessungen des erfindungsgemäßen Radantriebs die wirksame Bremskolbenfläche relativ groß zu gestalten.It is particularly favorable if the brake is one Has brake piston, which is arranged axially in front of the first planetary stage is. It is possible here, despite compact dimensions of the wheel drive according to the invention the effective Brake piston area relative big too shape.
Ein weiterer Vorteil ergibt sich dadurch, dass vor einer hydraulisch beaufschlagbaren Druckfläche des Bremskolbens ein Druckmittelkanal mündet, der im Achsrohr angeordnet ist.Another advantage arises in that in front of a hydraulically actuated pressure surface of the Brake piston opens a pressure medium channel, which is arranged in the axle tube is.
Es ist also nicht erforderlich, Druckmittelkanäle im Radkopf-Gehäuse vorzusehen. Sofern das Radkopf-Gehäuse mit der darin befindlichen Radwelle vom Achsrohr entfernt werden muss, beispielsweise um verschlissene Wellendichtringe auszutauschen, braucht der Druckmittelkanal für die Bremse nicht geöffnet zu werden.It is therefore not necessary to provide pressure medium channels in the wheel head housing. If the wheel head housing be removed from the axle tube with the wheel shaft inside must, for example, to replace worn shaft seals, needs the pressure medium channel for the brake is not released to become.
Gemäß einer im Hinblick auf geringen Verschleiss günstigen Ausgestaltung der Erfindung ist die Bremse als nass laufende Lamellenbremse, insbesondere Federspeicher-Lamellenbremse, ausgebildet.According to one with regard to low Wear cheap Embodiment of the invention is the brake as a wet-running multi-disc brake, especially spring-loaded multi-disc brake, educated.
Die erste Planetenstufe weist mit Vorteil ein Hohlrad auf, das am Außenumfang mit Radialfortsätzen zwecks verdrehfester Fixierung versehen ist, wobei in Umfangsrichtung zwischen den Radialfortsätzen Axialklauen des Bremskolbens angeordnet sind, die mit der Bremse in Wirkverbindung stehen.The first planetary stage advantageously has a ring gear, which is provided on the outer circumference with radial extensions for the purpose of non-rotatable fixing, the circumferential direction between the radial extensions zen axial claws of the brake piston are arranged, which are operatively connected to the brake.
Durch diese Konstruktion ist es also möglich, trotz Anordnung des Bremskolbens vor dem Planetengetriebe die im Bereich des Planetengetriebes befindliche Bremse zu betätigen. Hierbei erstrecken sich die Axialklauen in axialer Richtung durch die Aussparungen zwischen den Radialfortsätzen hindurch.So through this construction, it is possible despite Arrangement of the brake piston in front of the planetary gear in the area of the planetary gear brake to operate. Here extend the axial claws in the axial direction through the recesses between the radial processes therethrough.
Die Vorteile der Erfindung kommen besonders gut zur Geltung, wenn die erste Planetenstufe eingangsseitig mit einer Motorwelle eines elektrischen Fahrmotors gekoppelt ist. Für einen solchen, in der Regel batterie-elektrisch betriebenen Fahrantrieb sind geringe Verluste, wie sie mit dem erfindungsgemäßen Radantrieb ermöglicht werden, von erheblicher Bedeutung, um die eine möglichst lange Einsatzzeit mit einer Batterieladung zu erzielen.The advantages of the invention come particularly good if the first planetary stage is on the input side is coupled to a motor shaft of an electric traction motor. For one such, as a rule battery-powered drive low losses, as are made possible with the wheel drive according to the invention, of considerable importance in order to have the longest possible use with to achieve a battery charge.
