Abstract

The invention relates to a drive device (10, 10a, 10b, 10c, 10d) which has a sun wheel that is configured as a stator (12, 12a, 12b, 12c). Several grooves (18, 18c) are configured in the longitudinal direction. Said grooves form web-shaped poles (20) which are situated opposite each other in pairs and around which windings (22) that can be exposed to a current are arranged. The drive device (10, 10a, 10b, 10c, 10d) has at least one planet wheel, which is configured as a rotor (36, 36a, 36b), and at least one element (28, 28a, 28b, 40, 54) for at least rotationally mounting the at least one rotor (36, 36a, 36b). The invention is based on the combination of an electromotor and a planetary gear system to form a drive device (10, 10a, 10b, 10c, 10d). Two components are therefore combined into one, saving construction space and reducing weight and cost.

Description

AntriebsvorrichtungDrive device
Stand der TechnikState of the art
Die Erfindung betrifft eine Antriebsvorrichtung. Es sind Antriebsvorrichtungen bekannt, die aus einem Elektromotor, insbesondere einem Reluktanzmotor, und einem angeflanschten Getriebe bestehen. Es handelt sich also um zwei Komponenten. Dies bedeutet, daß ein relativ großer Bauraum notwendig ist und ein entsprechendes Gewicht anfällt.The invention relates to a drive device. Drive devices are known which consist of an electric motor, in particular a reluctance motor, and a flanged gear. So there are two components. This means that a relatively large amount of space is required and a corresponding weight is incurred.
Ferner werden bei Elektromotoren durch den Luftspalt zwischen dem Stator und dem Rotor Verluste verursacht, die sich nachteilig auf den Wirkungsgrad und somit die Leistung auswirken.In electric motors, the air gap between the stator and the rotor also causes losses which have a disadvantageous effect on the efficiency and thus on the performance.
Vorteile der ErfindungAdvantages of the invention
Die Antriebsvorrichtung mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß ein Elektromotor und ein Getriebe zu einer Komponente vereinigt sind. Diese erfordert weniger Bauraum und weist ein niedrigeres Gewicht auf .The drive device with the features of claim 1 has the advantage that an electric motor and a transmission are combined into one component. This requires less space and has a lower weight.
Der Wirkungsgrad der Antriebsvorrichtung ist gegenüber einem herkömmlichen Elektromotor erheblich verbessert, da die Oberfläche für den magnetischen Fluß vergrößert und der Luftspalt minimiert ist.The efficiency of the drive device is significantly improved compared to a conventional electric motor, because the Surface for the magnetic flux is increased and the air gap is minimized.
Wird in den Nuten der Pole ein nicht magnetisierbares Material so angeordnet, daß der Stator am ganzen, mit dem mindestens einen Rotor zusammenwirkenden Durchmesser eine Verzahnung aufweist, so ergibt sich ein guter Rundlauf. Dieser wir noch dadurch verbessert, daß mehrere Rotoren vorgesehen sind, die in einem Ringraum, der vom Stator und einem Element gebildet ist, angeordnet sind und daß das Element eine Verzahnung aufweist, die mit den verzahnten Rotoren kämmt .If a non-magnetizable material is arranged in the slots of the poles in such a way that the entire stator has teeth on the entire diameter, which cooperates with the at least one rotor, this results in good concentricity. This is further improved in that several rotors are provided, which are arranged in an annular space which is formed by the stator and an element, and in that the element has a toothing which meshes with the toothed rotors.
Dadurch, daß die Verzahnungen des Elements, des Stators und der Rotoren parallel zur Statorachse verlaufen und daß das Element so aus der Antriebsvorrichtung herausragt, daß ein Drehmoment abgreifbar ist, läßt sich auf einfache Weise ein elektromotorisches Planetengetriebe realisieren.Because the teeth of the element, the stator and the rotors run parallel to the stator axis and that the element protrudes from the drive device in such a way that a torque can be tapped, an electromotive planetary gear can be realized in a simple manner.
Verlaufen die Verzahnungen des Elements, des Stators und der Rotoren schraubenlinienformig zur Statorachse, so entspricht dies einem elektromotorischen Spindeltrieb, wobei sich für die Linearbewegung entweder die Rotoren oder das Element verwenden lassen.If the toothing of the element, the stator and the rotors is helical to the stator axis, this corresponds to an electromotive spindle drive, whereby either the rotors or the element can be used for the linear movement.
Die Verzahnung des Stators kann an dessen Innendurchmesser oder Außendurchmesser ausgebildet werden, wodurch ein Innenläufer oder ein Außenläufer realisierbar ist.The teeth of the stator can be formed on its inside diameter or outside diameter, whereby an inner rotor or an outer rotor can be realized.
Eine besonders einfache Ausbildung ergibt sich dadurch, daß ein Rotor vorgesehen ist, daß das Element als gekröpfte Welle ausgebildet ist, die in einer zentrischen Längsbohrung des Rotors drehbar angeordnet ist, daß die Welle an aus dem Rotor herausragenden Enden zwei parallele Stege aufweist, die senkrecht zur Welle angeordnet sind und zur Mittelachse des Stators reichen, und daß an den Stegen Wellenabschnitte ausgebildet sind, die in Längsrichtung aus der Antriebsvorrichtung ragen und an der Antriebsvorrichtung drehbar gelagert sind.A particularly simple design results from the fact that a rotor is provided, that the element is designed as a cranked shaft which is rotatably arranged in a central longitudinal bore of the rotor, that the shaft has two parallel webs at the ends projecting from the rotor, which are perpendicular are arranged to the shaft and extend to the central axis of the stator, and that on the webs shaft sections are formed which protrude in the longitudinal direction from the drive device and are rotatably mounted on the drive device.
Weitere Vorteile und vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen und der Beschreibung.Further advantages and advantageous further developments result from the subclaims and the description.

Beschreibung des AusführungsbeispielsDescription of the embodiment
In der Figur 1 ist eine Antriebsvorrichtung 10 gezeigt. Die Antriebsvorrichtung 10 weist ein als Stator 12 ausgebildetes Sonnenrad auf. Der Stator 12 ist vorteilhafterweise als Statorblechpaket aufgebaut . In Längsrichtung der Antriebsvorrichtung 10, die der Statorachse 14 entspricht, sind am Innendurchmesser 16 in gleichmäßigen Abständen sechs schwalbenschwanzförmige Nuten 18 ausgebildet, die drei, sich diametral gegenüberliegende Nutpaare 18', 18'', 18''' bilden. Die sechs Nuten 18 bilden sechs stegförmige Pole 20, die ihrerseits drei, sich diametral gegenüberliegende Polpaare 20', 20'', 20''' bilden. Um jeden Pol 20 derA drive device 10 is shown in FIG. The drive device 10 has a sun wheel designed as a stator 12. The stator 12 is advantageously constructed as a stator laminated core. In the longitudinal direction of the drive device 10, which corresponds to the stator axis 14, there are six on the inner diameter 16 at regular intervals dovetail-shaped grooves 18 are formed, which form three diametrically opposed pairs of grooves 18 ', 18'',18'''. The six grooves 18 form six bar-shaped poles 20, which in turn form three diametrically opposite pole pairs 20 ', 20'',20'''. Around each pole 20
Polpaare 20', 20'', 20''' ist eine bestrombare Wicklung 22 angeordnet. Der Stator 12 der Antriebsvorrichtung 10 weist somit den Aufbau des Stators eines sogenannten Reluktanzmotors auf. Die Wicklungen 22 der Polpaare 20', 20'', 20''' sind daher in bekannter Weise nacheinander so bestrombar, daß ein magnetisches Drehfeld erzeugbar ist. Vorteilhafterweise ist in den Nuten 18 ein nichtmagnetisierbares Material 24 so angeordnet, daß der Stator 12 am ganzen Innendurchmesser 16, auch an den durch die Nuten 20 unterbrochenen Stellen eine Verzahnung 26 aufweist. Bei dem Material 24 kann es sich beispielsweise um einen Kunststoff oder ein Harz handeln, mit dem der Stator 12 nach der Montage der Wicklungen 22 ausgegossen wird. Die Verzahnung 26 kann beispielsweise beim Ausgießen des Stators 12 mit einem entsprechend geformten Werkzeug, das in den Stator 12 geführt wird und die Form der Verzahnung 26 aufweist, hergestellt werden. Es ist auch möglich, die Verzahnung 26 nach dem Ausgießen durch eine spanende Bearbeitung herzustellen.Pole pairs 20 ′, 20 ″, 20 ″ ″ have a winding 22 that can be supplied with current. The stator 12 of the drive device 10 thus has the structure of the stator of a so-called reluctance motor. The windings 22 of the pole pairs 20 ', 20' ', 20' '' can therefore be energized in succession in a known manner so that a rotating magnetic field can be generated. A non-magnetizable material 24 is advantageously arranged in the grooves 18 in such a way that the stator 12 has a toothing 26 over the entire inner diameter 16, also at the points interrupted by the grooves 20. The material 24 can be, for example, a plastic or a resin with which the stator 12 is poured out after the windings 22 have been installed. The toothing 26 can be produced, for example, when the stator 12 is poured out using a correspondingly shaped tool which is guided into the stator 12 and has the shape of the toothing 26. It is also possible to produce the toothing 26 after the pouring by machining.
In Längsrichtung der Antriebsvorrichtung 10 beziehungsweise zentrisch zum Stator 12 und fluchtend mit der Statorachse 14 weist die Antriebsvorrichtung 10 ein drehbar an der Antriebsvorrichtung 10 gelagertes Element 28 auf, dessen Außendurchmesser 30 eine Verzahnung 32 aufweist. Das Element 28 hat die Funktion eines Abtriebselements. Das Element 28 ragt aus der Antriebsvorrichtung 10 heraus und hat außerhalb der Antriebsvorrichtung 10 die Form einer Abtriebswelle, wodurch ein Drehmoment am Element 28 abgreifbar ist. Die Lagerung erfolgt hierbei in bekannter Weise an nicht dargestellten Gehäuseteilen der Antriebsvorrichtung 10, beispielsweise einem vorderen und hinteren Flansch. Das Element 28 und der Innendurchmesser 16 des Stators 12 bilden einen Ringraum 34. Im Ringraum 34 sind vier als Rotoren 36 ausgebildete Planetenräder angeordnet, wobei auch eine andere Anzahl möglich ist. Die vier Rotoren 36 bilden zwei Rotorpaare 36', 36'', die sich diametral gegenüberliegen. Die Verzahnung 32 des Elements 28 kämmt mit einer Außenverzahnung 37 der Rotoren 36 und dient somit ebenfalls der drehbaren Lagerung der Rotoren 36. Hier zeigt sich auch, daß es vorteilhaft ist, in den Nuten 18 das nicht magnetisierbare Material 24 vorzusehen, da der Stator 12 dadurch am ganzen, mit den Rotoren 36 zusammenwirkenden Innendurchmesser 16 eine Verzahnung 26 aufweist, wodurch der Rundlauf der Antriebsvorrichtung 10 verbessert wird. Die Rotoren 36 können zur Lagerung an ihren Stirnseiten 38 mit jeweils einem - mit gestrichelten Linien angedeuteten - Ring 40 verbunden sein. Dadurch ist es möglich, auf das Material 24 zu verzichten.In the longitudinal direction of the drive device 10 or centered on the stator 12 and in alignment with the stator axis 14, the drive device 10 has an element 28 rotatably mounted on the drive device 10, the outer diameter 30 of which has a toothing 32. The element 28 has the function of an output element. The element 28 protrudes from the drive device 10 and has the shape of an output shaft outside the drive device 10, as a result of which a torque can be tapped off from the element 28. The storage takes place in a known manner on housing parts of the drive device 10, not shown for example a front and rear flange. The element 28 and the inner diameter 16 of the stator 12 form an annular space 34. In the annular space 34, four planet gears designed as rotors 36 are arranged, a different number also being possible. The four rotors 36 form two pairs of rotors 36 ', 36'', which are diametrically opposed. The toothing 32 of the element 28 meshes with an external toothing 37 of the rotors 36 and thus also serves for the rotatable mounting of the rotors 36. It also shows here that it is advantageous to provide the non-magnetizable material 24 in the grooves 18 since the stator 12 thereby has a toothing 26 on the entire inner diameter 16 cooperating with the rotors 36, as a result of which the concentricity of the drive device 10 is improved. The rotors 36 can be connected to their end faces 38 each with a ring 40 - indicated by dashed lines. This makes it possible to dispense with the material 24.
Wie aus der Figur 2 ersichtlich ist, verlaufen dieAs can be seen from FIG. 2, the
Verzahnung 26 des Stators 12, die Verzahnung 32 des Elements 28 und die Außenverzahnung 37 der Rotoren 32 parallel zur Längsrichtung der Antriebsvorrichtung 10 beziehungsweise zur Statorachse 14.Teeth 26 of the stator 12, the teeth 32 of the element 28 and the outer teeth 37 of the rotors 32 parallel to the longitudinal direction of the drive device 10 or to the stator axis 14.
Werden die Wicklungen 22 der Polpaare 20', 20'', 20''' bestromt, so wird ein Magnetfeld aufgebaut, das auf Teile, die aus einem auf ein Magnetfeld reagierendes Material bestehen, eine Kraft ausübt. Durch entsprechendes Bestromen der Wicklungen 22, wie es zum Beispiel bei einemIf the windings 22 of the pole pairs 20 ', 20' ', 20' '' are energized, a magnetic field is built up which exerts a force on parts which consist of a material which reacts to a magnetic field. By appropriately energizing the windings 22, such as in one
Reluktanzmotor üblich ist, wird ein magnetisches Drehfeld erzeugt, wodurch sich die Rotorpaare 36', 36'' drehen.Reluctance motor is common, a magnetic rotating field is generated, whereby the rotor pairs 36 ', 36' 'rotate.
Bewegt sich ein als Rotor 36 ausgebildetes Planetenrad, so rollt es mit seiner Außenverzahnung 37 im Gegenuhrzeigersinn entlang der am Innendurchmesser 16 des Stators 12 ausgebildeten Verzahnung 26 ab und auf einen Pol 20 zu. Durch die Drehbewegung eines Rotors 36, die durch die magnetische Anziehungskraft eines Pols 20 ausgeübt wird, dreht sich zwangsläufig, wie bei einem Planetengetriebe, auch das Element 28. Rollt ein Rotor 36 entlang derIf a planet gear designed as a rotor 36 moves, its external toothing 37 rolls counterclockwise along the internal diameter 16 of the stator 12 trained toothing 26 from and towards a pole 20. Due to the rotary movement of a rotor 36, which is exerted by the magnetic attraction force of a pole 20, the element 28 inevitably rotates, as in the case of a planetary gear, and a rotor 36 rolls along the
Verzahnung 26 des Stators 12 im Uhrzeigersinn, so dreht sich ein Rotor 36 im Gegenuhrzeigersinn um die eigene Längsachse. Dadurch wird das Element 28 im Uhrzeigersinn gedreht. Die Drehbewegung des Elements 28 und das übertragbare Drehmoment lassen sich an einem aus der Antriebsvorrichtung 10 herausragenden Ende des Elements 28, das als Wellenende ausgebildet ist, in bekannter Weise abgreifen.Teeth 26 of the stator 12 clockwise, a rotor 36 rotates counterclockwise about its own longitudinal axis. As a result, the element 28 is rotated clockwise. The rotational movement of the element 28 and the transmissible torque can be tapped in a known manner at an end of the element 28 which protrudes from the drive device 10 and is designed as a shaft end.
Die Antriebsvorrichtung 10 aus den Figuren 1 und 2 stellt die Vereinigung eines Räder-Umlaufgetriebes in Form eines Planetengetriebes und eines Elektromotors, insbesondere eines Reluktanzmotors dar. Auf diese Weise ist es also möglich, statt eines Elektromotors und eines angeflanschten Getriebes nur eine Komponente zu verwenden, wodurch Bauraum, Gewicht und Kosten einsparbar sind. Durch die ineinander greifenden Verzahnungen 37, 26 des Stators 12 und der Rotoren 36 ist die zwischen ihnen wirksame Oberfläche vergrößert, wodurch der Wirkungsgrad steigt und somit die Leistung. Die erforderliche Übersetzung kann auf einfache Weise wie bei einem Umlauf-Rädergetriebe durch die Wahl der Durchmesser des Stators 12, des Elements 28 sowie der Rotoren 36 erreicht werden.The drive device 10 from FIGS. 1 and 2 represents the combination of an epicyclic gear in the form of a planetary gear and an electric motor, in particular a reluctance motor. In this way it is possible to use only one component instead of an electric motor and a flanged gear, which saves installation space, weight and costs. The interlocking toothings 37, 26 of the stator 12 and the rotors 36 increase the surface area between them, which increases the efficiency and thus the performance. The required transmission ratio can be achieved in a simple manner, as in the case of a planetary gear train, by the choice of the diameter of the stator 12, the element 28 and the rotors 36.
In der Figur 3 ist eine Antriebsvorrichtung 10a dargestellt, wobei die Verzahnung 26a des Stators 12a, die Verzahnung 32a des Elements 28a und die Verzahnung 37a der Rotoren 36a schraubenlinienformig zur Längsrichtung der Antriebsvorrichtung 10 beziehungsweise zur Statorachse 14 verlaufen. Das Element 28a ist in diesem Fall axial festgelegt, beispielsweise - je nach Belastungsfall - durch ein oder zwei Kugellager 42, wobei in der Figur 3 eines symbolisch dargestellt ist. Das Element 28a dient in diesem Fall alleine der Lagerung der Rotoren 36a. Die Rotoren 36a sind axial bewegbar. Sie sind drehbar auf Stangen 44 gelagert, die über die Antriebsvorrichtung 10a hinausragen. An den außerhalb der AntriebsVorrichtung 10a liegenden Enden der Stangen 44 ist eine Platte 46 angebracht. Eine solche Platte 46 kann auch an beiden Enden der Stangen 44 angebracht sein, wenn diese aus der Antriebsvorrichtung 10a herausragen. Die Stangen 44 sind axial verschiebbar gelagert. Bei einer Drehbewegung der Rotoren 36a um ihre eigene Achse, die einer Stange 44 entspricht, werden die Stangen 44 axial verschoben. Über die Platte 46 kann eine Zug- oder Druckkraft abgenommen werden. Auf diese Weise fungiert die Antriebsvorrichtung 10a als Steller, der wie ein Spindeltrieb einsetzbar ist. Für den erforderlichen Hub müssen die Längen des Stators 12a, des Elements 28a sowie der Rotoren 36 aufeinander abgestimmt sein. Der nutzbare Hub entspricht in etwa der Länge der Rotoren 36a abzüglich der Länge des Gehäuses der Antriebsvorrichtung 10a.FIG. 3 shows a drive device 10a, the toothing 26a of the stator 12a, the toothing 32a of the element 28a and the toothing 37a of the rotors 36a extending helically to the longitudinal direction of the drive device 10 or to the stator axis 14. In this case, the element 28a is fixed axially, for example - depending on the load - by one or two ball bearings 42, one in FIG is represented symbolically. In this case, the element 28a serves solely to support the rotors 36a. The rotors 36a are axially movable. They are rotatably mounted on rods 44 which protrude beyond the drive device 10a. A plate 46 is attached to the ends of the rods 44 outside the drive device 10a. Such a plate 46 can also be attached to both ends of the rods 44 when they protrude from the drive device 10a. The rods 44 are axially displaceable. When the rotors 36a rotate about their own axis, which corresponds to a rod 44, the rods 44 are axially displaced. A tensile or compressive force can be removed via the plate 46. In this way, the drive device 10a functions as an actuator that can be used like a spindle drive. The lengths of the stator 12a, the element 28a and the rotors 36 must be matched to one another for the required stroke. The usable stroke corresponds approximately to the length of the rotors 36a minus the length of the housing of the drive device 10a.
In der Figur 4 ist eine Antriebsvorrichtung 10b gezeigt, die ähnlich der Antriebsvorrichtung 10a ist. Sie unterscheidet sich dadurch, daß das Element 28b axial bewegbar ist und daß die Rotoren 36b axial festgelegt sind. Die Rotoren sind vorteilhafterweise über Kugellager 48 axial festgelegt, wobei auch eine andere Lagerung geeignet sein kann. Dadurch können sich die Rotoren 36b um die eigene Achse drehen und auch entlang der Verzahnung 26b des Stators 12b umlaufen.FIG. 4 shows a drive device 10b which is similar to the drive device 10a. It differs in that the element 28b is axially movable and in that the rotors 36b are axially fixed. The rotors are advantageously fixed axially via ball bearings 48, although another bearing can also be suitable. As a result, the rotors 36b can rotate about their own axis and can also run along the toothing 26b of the stator 12b.
Das Element 28b ragt aus der Antriebsvorrichtung 10b heraus. Der nutzbare Hub entspricht in etwa der Länge des Elements 28b abzüglich der Länge des Gehäuses der Antriebsvorrichtung 10b. Das Element 28b dient in diesem Fall der Lagerung der Rotoren 36b und der Übertragung einer Zug- oder Druckkraft nach außen. Für diese Übertragung ist es vorteilhaft ein oder beide Enden des Elements 28b ähnlich der Welle eines an und für sich bekannten Spindeltriebs auszubilden.The element 28b protrudes from the drive device 10b. The usable stroke corresponds approximately to the length of the element 28b minus the length of the housing of the drive device 10b. In this case, the element 28b serves to support the rotors 36b and to transmit a tensile or compressive force to the outside. For this transmission, it is advantageous or to form both ends of the element 28b similar to the shaft of a spindle drive known per se.
Die in der Figur 5 dargestellte Antriebsvorrichtung 10c entspricht einem Außenläufer. Der Stator 12c hat eineThe drive device 10c shown in FIG. 5 corresponds to an external rotor. The stator 12c has one
Sternform, wobei die sechs Pole 20c nach außen ragen und drei sich diametral gegenüberliegende Polpaare 20c' , 20c' ' , 20c' ' ' bilden. Die Nuten 18c zwischen den Polen 20c sind ebenfalls mit einem nicht magnetischen Material 24c versehen. Die Verzahnung 26c des Stators 12c ist an dessenStar shape, the six poles 20c projecting outwards and forming three diametrically opposite pole pairs 20c ', 20c' ', 20c' ''. The grooves 18c between the poles 20c are also provided with a non-magnetic material 24c. The teeth 26c of the stator 12c is on the other
Außendurchmesser 50 ausgebildet. Am Außendurchmesser 50 sind symmetrisch, beziehungsweise vier Rotoren 36 angeordnet, die zwei sich diametral gegenüberliegende Rotorpaare 36', 36'' bilden. Die Rotoren 36 sind an den Stirnseiten 38 über je einen Ring 40 miteinander verbunden, das als Element zurOutside diameter 50 formed. On the outer diameter 50, four rotors 36 are arranged symmetrically, which form two diametrically opposite rotor pairs 36 ', 36' '. The rotors 36 are connected to each other at the end faces 38 via a ring 40, which as an element for
Lagerung der Rotoren 36 dient und an dem auch ein Drehmoment abgenommen werden kann.Bearing of the rotors 36 is used and from which a torque can also be taken.
Aus den Figuren 6 und 7 geht eine Antriebsvorrichtung lOd hervor, wobei der Stator 12 der Antriebsvorrichtung 10 verwendet wird. Es ist nur ein Rotor 52 vorgesehen, der eine Außenverzahnung 53 aufweist, die zum Eingriff in die Verzahnung 26 des Stators 12 bestimmt ist. Ein Element, das der Lagerung des Rotors 52 und der Übertragung eines Drehmoments dient, ist als gekröpfte Welle 54 ausgebildet. Die Welle 54 ist in einer zentrischen Längsbohrung 56 des Rotors 52 drehbar angeordnet. An den Enden der Welle 54, die aus dem Rotor 52 herausragen, weist die Welle 54 zwei parallele Stege 58 auf, die senkrecht zur Welle 54 angeordnet sind und zur Statorachse 14 reichen. An den Stegen 58 sind Wellenabschnitte 60 ausgebildet, die in Längsrichtung aus der Antriebsvorrichtung 12c ragen. Sie sind über Lager 62 der Antriebsvorrichtung 12d drehbar gelagert. Die Stege 58 können mit der Welle 54 und den Wellenabschnitten 60 beispielsweise verschraubt sein. Diese Antriebsvorrichtung lOd stellt eine besonders einfach aufgebaute Ausbildung dar.A drive device 10d can be seen from FIGS. 6 and 7, the stator 12 of the drive device 10 being used. Only one rotor 52 is provided, which has an external toothing 53 which is intended for engagement in the toothing 26 of the stator 12. An element that serves to support the rotor 52 and to transmit a torque is designed as a cranked shaft 54. The shaft 54 is rotatably arranged in a central longitudinal bore 56 of the rotor 52. At the ends of the shaft 54 which protrude from the rotor 52, the shaft 54 has two parallel webs 58 which are arranged perpendicular to the shaft 54 and extend to the stator axis 14. Shaft sections 60 are formed on the webs 58 and protrude in the longitudinal direction from the drive device 12c. They are rotatably supported by bearings 62 of the drive device 12d. The webs 58 can be screwed to the shaft 54 and the shaft sections 60, for example. This Drive device 10d represents a particularly simple construction.
Selbstverständlich ist die Erfindung nicht nur auf die beschriebene Antriebsvorrichtung und deren Abwandlungen beschränkt. Es ist auch möglich statt einer formschlüssigen Übertragung der Drehmomente durch die Verzahnungen 26, 37a, 53 der Antriebsvorrichtungen 10, 10c und lOd eine reibschlüssige Übertragung beispielsweise durch Reibräder vorzusehen. Kern der Erfindung ist, daß ein Elektromotor und ein Umlauf-Rädergetriebe zu einer Antriebsvorrichtung kombiniert werden. Hierzu ist im wesentlichen das Sonnenrad als Stator eines Elektromotors, insbesondere eines Reluktanzmotors, auszubilden und das mindestens eine Planetenrad als Rotor, wobei noch wenigstens ein Element vorgesehen sein muß, das zumindest der Lagerung des mindestens eine Rotors dient. Es ist auch denkbar, für den oder die Rotoren zusätzliche Wicklungen vorzusehen, wodurch allerdings der Aufwand, diese elektrisch zu verbinden, größer wird. Of course, the invention is not only limited to the drive device described and its modifications. Instead of a positive transmission of the torques by the toothings 26, 37a, 53 of the drive devices 10, 10c and 10d, it is also possible to provide a frictional transmission, for example by friction wheels. The essence of the invention is that an electric motor and a planetary gear train are combined to form a drive device. For this purpose, essentially the sun gear is to be designed as a stator of an electric motor, in particular a reluctance motor, and the at least one planet gear is to be designed as a rotor, at least one element also having to be provided which serves at least to support the at least one rotor. It is also conceivable to provide additional windings for the rotor or rotors, but this increases the effort involved in electrically connecting them.
