Die vorliegende Erfindung bezieht sich auf ein elektrodynamisches Antriebsaggregat mit einen Antriebsmotor, dessen mit konstanter Drehzahl laufende Abtriebswelle mit einer regalbaren Kupplung verbunden ist.The present invention relates to an electrodynamic drive unit with a drive motor, the output shaft running at constant speed is connected to a shiftable clutch.
In vielen Bereichen der Technik ist es wünschenswert oder gar erforderlich, über ein Antriebs-Aggregat zu verfügen das einerseits von einer mit konstanter Drehzahl laufenden Maschine angetrieben werden kann und das andererseits eine Abtriebswelle aufweist, deren Drehzahl verändert werden kann. Ein wesentlicher Gesichtspunkt bei einem solchen An— triebs-Aggregat ist der Wirkungsgrad. Die Verluste, insbesondere innerhalb der Kupplung bzw. des Getriebes müssen auf einen möglichst niedrigen Wert gehalten werden, damit ein möglichst grosser Anteil der eingegebenen Leistung am Ausgang des Aggregates zur Verfügung steht.In many areas of technology it is desirable or even necessary to have a drive unit which on the one hand can be driven by a machine running at constant speed and on the other hand has an output shaft whose speed can be changed. An essential aspect of such an approach The driving unit is the efficiency. The losses, especially within the clutch or the gearbox, must be kept at the lowest possible value, so that the largest possible proportion of the entered power in the Output of the unit is available.
Von ganz besonderem Interesse ist ein Antriebsaggregat dessen Abtriebsdrehzahl stufenlos verändert werden kann. Eine bekannte Lösung besteht gemäss Fig. 1 darin, z.B. von einem Dieselmotor 2 über eine Welle 3 eine Oelkupplung bzw. einen hydraulischen Drehmoment-Wandler 1 anzutreiben. Die Abtreibswelle 4 kann dann durch Regelung des Wandlers 1 in der Drehzahl beeinflusst werden. Eine andere bekannte Lösung gemäss Fig. 2 sieht einen Dieselmotor 2 vor, dessen Abtriebswelle 3A drive unit whose output speed can be continuously varied is of particular interest. One 1 known solution consists in, for example, of a diesel engine 2 via a shaft 3 an oil clutch or an oil clutch hydraulic torque converter 1 to drive. The output shaft 4 can then be speed controlled by the converter 1 to be influenced. Another known solution according to FIG. 2 provides a diesel engine 2, the output shaft 3

(ο(ο
eine Wirbel strom-Kupplung 5 antreibt. Auch hier ist durch eine Regelung der Kupplung 5 eine Beeinflussung der Drehzahl der Abtriebswelle 4 möglich. Diese bekannten Lösungen arbeiten aber mit schlechtem Wirkungsgrad, da die Verluste im hydraulischen Drehmoment-Wandler 1 bzw. in der Wirbelstrom-Kupplung 5 sehr hoch sind. Auch eine Drehrichtsumkehr ist mit diesen Lösungen nicht möglich.an eddy current clutch 5 drives. Also here is through one Regulation of the clutch 5, influencing the speed of the output shaft 4 is possible. These known solutions work but with poor efficiency, since the losses in the hydraulic torque converter 1 or in the eddy current clutch 5 are very high. Reversing the direction of rotation is also not possible with these solutions.
Ein besserer Wirkungsgrad ist mit einer bekannten Anordnung gemäss Fig. 3 zu erzielen, wobei ein Dieselmotor 2 über eine Welle 3 eine mechanische oder elektro-magnetische Kupplung 6 antreibt, die ihrerseits mit einem schaltbaren Stufengetriebe 7 gekoppelt ist. Der Nachteil dieser Lösung ist aber darin zu sehen, dass keine stufenlose Regelung der Drehzahl der Abtriebswelle 4 möglich ist. Bei einer Ward-Leonard-Anordnung gemäss Fig. 4 treibt die Welle 3 des Dieselmotors 2 einen Generator 8 an, der mit einem Stellglied 9 regelbar ist und der seinerseits einen Motor 10 speist, dessen Abtriebswelle 4 in Bezug auf die Drehzahl regelbar ist. Ein ähnliches Prinzip ist in Fig. 5 skizziert, wo ein Dieselmotor 2 eine Pumpe 11 antreibt, die einen Hydromotor 12 speist. Durch Beeinflussung der Förderleistung der Pumpe 11 ist die Drehzahl der Abtriebswelle 4 veränderlich. In Fig. 6 schliesslich ist eine bekannte Lösung dargestellt, bei der ein Drehstrom-Motor 13 über einen regelbaren Frequenzumformer 14 gespiesen wird, so dass durch Beeinflussung des Frequenzumformers die Drehzahl der Abtriebswelle 4 des Motors 13 regelbar ist.A better efficiency can be achieved with a known arrangement according to FIG. 3, with a diesel engine 2 via a Shaft 3 a mechanical or electromagnetic clutch 6 drives, which in turn is coupled to a switchable multi-step transmission 7. The disadvantage of this solution, however, is in that to see that no stepless regulation of the speed of the output shaft 4 is possible. With a Ward-Leonard arrangement According to FIG. 4, the shaft 3 of the diesel engine 2 drives a generator 8 which can be regulated with an actuator 9 and which in turn feeds a motor 10, the output shaft 4 of which can be regulated in terms of speed. A similar principle is sketched in FIG. 5, where a diesel engine 2 drives a pump 11 which feeds a hydraulic motor 12. By influencing the delivery rate of the pump 11, the speed of the output shaft 4 is variable. Finally, in FIG. 6 there is one known solution shown in which a three-phase motor 13 is fed via a controllable frequency converter 14, so that the speed of the output shaft 4 of the motor 13 can be regulated by influencing the frequency converter.

Obwohl der Wirkungsgrad der bekannten Anordnungen gemäss Figuren 4 bis 6 besser als bei den zuerst genannten Lösungen ist, ist er doch nicht so hoch wie es technisch wünschenswert wäre. Als weiterer Nachteil ist die komplizierte und aufwendige Bauart dieser bekannten Lösungen zu erwähnen und auch die Tatsache, dass eine beträchtliche Regelenergie aufgewendet werden muss.Although the efficiency of the known arrangements according to FIGS. 4 to 6 is better than that of the first mentioned Solutions, it is not as high as it would be technically desirable. Another disadvantage is that it is complicated and elaborate construction of these known solutions and also the fact that a considerable Control energy must be used.
Es ist das Ziel der vorliegenden Erfindung, ein Antriebs-Aggregat vorzuschlagen, dass diese Nachteile nicht mehr aufweist und mit Hilfe dessen eine stufenlos regelbare Drehzahl- bzw. Drehmoment-Wandlung realisierbar ist, die nur einen sehr geringen Prozentsatz an Regelenergie verlangt, die kompakt und einfach aufgebaut ist und die mit sehr gutem Wirkungsgrad arbeitet. Dies wird bei einem Antriebs-Aggregat der eingangs genannten Art gemäss der Erfindung dadurch erreicht, dass die Kupplung einen Drehstrom-Generator aufweist, dessen Nebenschlusswicklung an ein Steuergerät mit variabler Spannung und Frequenz angeschlossen ist, und dass ein mit dem Drehstrom-Generator verbundener Käfigläufermotor vorgesehen ist, dessen Abtriebswelle durch Aenderung von Spannung und/oder Frequenz im Steuergerät in Bezug auf die Drehzahl und Drehsinn beeinflussbar ist.It is the aim of the present invention to propose a drive unit that eliminates these disadvantages has and with the help of which a continuously variable speed or torque conversion can be realized, the only requires a very small percentage of control energy, which is compact and simple and which is very good Efficiency works. In the case of a drive unit of the type mentioned at the outset, this is achieved according to the invention by that the clutch has a three-phase generator whose shunt winding to a control unit with variable Voltage and frequency is connected, and that a squirrel cage motor connected to the three-phase generator is provided is whose output shaft by changing the voltage and / or frequency in the control unit in relation to the speed and direction of rotation can be influenced.

Fig. 7 shows the basic arrangement as it is according to the invention is suggested. A drive machine 15, for example an internal combustion engine running at constant speed, overdrives a shaft 16 to a three-phase generator 17.

The generator 17 feeds a squirrel cage motor 36, whose output shaft 37 can be regulated with respect to the speed by influencing the control unit 19 accordingly. the The feed frequency supplied to the motor 36 is dependent on the rotational speed of the rotor of the generator 17, the Number of pole pairs and the field frequency and can be specified as follows:

Eine praktische Ausführungsmoglichkeit ist in Fig. 8 schematisch skizziert. Ein Verbrennungsmotor 15 treibt über Welle 16 den Rotor 20 des Generator-Teiles an. Zu einem kleinen Teil ist dieser Rotor 20 von einer Feldspule 21 umgeben, die an das Steuergerät 22 angeschlossen ist. Zum grösseren Teil umgibt der Käfigläufer 23 des Motorteiles den Rotor 20, wobei die Teile 20, 21 und 23 koaxial so angeordnet sind, dass zwischen Rotor 20 und Feldspule 21 einerseits und Rotor 20 und Läufer 23 andererseits ein geringer Luftspalt ausgebildet ist. An den Käfigläufer 23 ist die Abtriebswelle 23 des Aggregates starr angekoppelt. Es entsteht so ein kompakter Wandler, dessen Abtrxebswellendrehzahl durch Regelung des Steuergeräts veränderbar ist.A practical embodiment is shown schematically in FIG outlined. An internal combustion engine 15 drives the rotor 20 of the generator part via shaft 16. To a small one This rotor 20 is partially surrounded by a field coil 21 which is connected to the control unit 22. To the bigger one Part of the cage rotor 23 of the motor part surrounds the rotor 20, the parts 20, 21 and 23 being arranged coaxially so that A small air gap is formed between rotor 20 and field coil 21 on the one hand and rotor 20 and rotor 23 on the other hand is. The output shaft 23 of the assembly is rigidly coupled to the squirrel cage rotor 23. The result is a compact one Converter whose output shaft speed can be changed by regulating the control unit.
Wenn der Rotor 20 mit konstanter Drehzahl von der Maschine 15 angetrieben wird, erzeugt er ein Drehfeld mit der Fre- quenz F .In die Feldwicklung 21 wird andererseits ein in der Frequenz regulierter Strom eingespiesen, so dass sich ein Drehfeld mit der Frequenz F.. einstellt. Das resultierendeWhen the rotor 20 is at constant speed from the machine 15 is driven, it generates a rotating field with the frequency F. On the other hand, an in The frequency regulated current is fed in, so that a rotating field with the frequency F .. is established. The resulting
Drehfeld F = F_ + F ist magnetisch gekoppelt mit dem Läufer m χ ~— rRotating field F = F_ + F is magnetically coupled to the rotor m χ ~ - r
23, welcher mit geringfügiger Nacheilung diesem Drehfeld folgt und die Welle 24 antreibt. Es ist leicht einzusehen, dass so die Drehzahl der Welle 24 beeinflusst werden kann, in dem die Frequenz, die vom Steuergerät 22 an die Feldspule 21 abgegeben wird, veränderlich ist. Versuche haben gezeigt, dass nur etwa 2 % der Gesamtenergie zur Regelung aufzuwenden sind. Für die Grosse des an Welle 24 auftretenden Drehmomentes ist der Feldstrom in der Spule 21 bestimmend.23, which follows this rotating field with a slight lag and drives the shaft 24. It is easy to see that the speed of the shaft 24 can be influenced in this way by changing the frequency that is output from the control device 22 to the field coil 21. Tests have shown that only about 2 % of the total energy has to be used for regulation. The field current in the coil 21 is decisive for the magnitude of the torque occurring at the shaft 24.

Falls die Feldspule 21 mit Gleichstrom gespeist wird, ist nur das durch den Läufer 2O erzeugte Drehfeld massgebend. Da der Läufer 20 über einen Luftspalt mit dem Käfigläufer 23 magnetisch gekoppelt ist, wird letzterer mit geringer Nacheilung diesem Drehfeld folgen, so dass das Uebersetzungsverhältnis zwischen Antriebswelle 16 und Abtriebswelle 23 ungefähr 1 : 1 ist. Falls die Feldspule 21 mit Drehstrom gespeist wird, kann, je nach Drehrichtung der Felder und je nach Frequenz eine höhere oder niedrigere Drehzahl bzw. eine Umkehr der Drehrichtung der Abtriebswelle 24 erreicht werden. Es hat sich dabei gezeigt, dass unabhängig vom eingestellten Uebersetzungsverhältnis ein Wirkungsgrad von bis zu 95 % realiesiert werden kann.If the field coil 21 is fed with direct current, only the rotating field generated by the rotor 2O is decisive. Since the rotor 20 is magnetically coupled to the squirrel cage rotor 23 via an air gap, the latter will follow this rotating field with little lag, so that the transmission ratio between the drive shaft 16 and output shaft 23 is approximately 1: 1. If the field coil 21 is fed with three-phase current, depending on the direction of rotation of the fields and depending on the frequency, a higher or lower speed or a reversal of the direction of rotation of the output shaft 24 can be achieved. It has been shown that regardless of the gear ratio set, an efficiency of up to 95% can be achieved.

Käfigläufer 26 gekoppelt, während das Sonnenrad 34 vom Rotor 30 angetrieben wird.Squirrel-cage rotor 26 coupled, while the sun gear 34 from the rotor 30 is driven.
Zwischen der Statorwicklung 25 und der äusseren Wicklung 25 des Läufers 26 befindet sich ein Luftspalt,so dass diese beiden Wicklungen magnetisch gekoppelt sind. In entsprechender Weise ist zwischen der inneren Wicklung 28 des Läufers 26 einerseits und der Feldregel spule 29 sowie der Rotorwicklung 31 andererseits ein Luftspalt ausgebildet, was eine magnetische Koppelung dieser Wicklungen untereinander bewirkt. Bei einer-Speisung der Wicklung 25 mit Drehstrom bildet sich ein Drehfeld aus, welchem der Käfigläufer 26 unter Einfluss seiner äusseren Wicklung 27 folgt, so dass der Läufer 26 das Kronenrad 32 mit konstanter Drehzahl antreibt. Auf die Wicklung 31 des Rotors 30 wirken zwei Drehfelder, nämlich das voncfer inneren Wicklung 28 des konstant drehenden Läufers 26 erzeugte Drehfeld F und das von der Wicklung 29 der Feldregelspule erzeugte Drehfeld Ff. Das letztere Drehfeld ist in Bezug auf Frequenz und Drehrichtung variabel, da die Spule 29 an ein Steuergerät angeschlossen ist, das wie vorstehend schon beschrieben regelbar ist.There is an air gap between the stator winding 25 and the outer winding 25 of the rotor 26, so that these two windings are magnetically coupled. In a corresponding manner, an air gap is formed between the inner winding 28 of the rotor 26 on the one hand and the field control coil 29 and the rotor winding 31 on the other hand, which causes a magnetic coupling of these windings with one another. When the winding 25 is supplied with three-phase current, a rotating field is formed which the cage rotor 26 follows under the influence of its outer winding 27, so that the rotor 26 drives the crown gear 32 at a constant speed. Two rotating fields act on the winding 31 of the rotor 30, namely the rotating field F generated by the inner winding 28 of the constantly rotating rotor 26 and the rotating field F f generated by the winding 29 of the field regulating coil. The latter rotating field is variable in terms of frequency and direction of rotation, since the coil 29 is connected to a control device which can be regulated as already described above.
Je nach Frequenz und Richtung des von der Spule 29 erzeugten Drehfeldes wird sich der Rotor 30 schneller oder langsamer drehen und damit das Sonnenrad 34 entsprechend antreiben. Aus der relativen Winkelgeschwindigkeit von Kronenrad 32 und Sonnenrad 34 resultiert eine Drehung des Planetenradträgers 33 und damit der Abtriebswelle 35.Depending on the frequency and direction of the generated by the coil 29 The rotating field will rotate the rotor 30 faster or slower and thus drive the sun gear 34 accordingly. A rotation of the planetary gear carrier results from the relative angular velocity of the face gear 32 and the sun gear 34 33 and thus the output shaft 35.

Mit dieser Ausführung ist ein Nebenschlussantrieb geschaffen, in dem ein Käfigläufermotor mit regulierbarer Kuppplung und mechanischem Reduktionsgetriebe zu einer Einheit zusammengebaut ist, die sehr kompakt und einfach aufgebaut ist und die ein nahezu verlustfreies und dabei stufenloses regeln der Drehzahl der Abtriebswelle gestattet. Die Antriebseinheit weist dabei stets eine Koppelung von Antriebs- und Abtriebswelle auf, so dass sich bei Schiebebetrieb die in den meisten Fällen aus Sicherheitsgründen erwünschte Bremswirkung ergibt.With this design, a shunt drive is created in which a squirrel cage motor with an adjustable clutch and mechanical reduction gear is assembled into a unit that is very compact and simple and which allows an almost loss-free and infinitely variable control of the speed of the output shaft. The drive unit always has a coupling of the drive and output shaft, so that the in in most cases results in the desired braking effect for safety reasons.
