Abstract

The invention relates to a hybrid drive system for vehicles, in particular passenger vehicles, with a reciprocating-piston internal combustion engine having a crankshaft and with an electric motor having a rotor and a stator, which can be connected alternatively to the driving wheels of the vehicle via clutches and a change-speed transmission. In order to achieve particularly efficient and effective functioning of a drive system of this kind, it should be possible to connect the flywheel-less crankshaft (6) of the reciprocating-piston internal combustion engine (1) directly, via a first clutch (4), to the rotor (8) of the electric motor (2), which rotor acts as a flyweight for the drive motor, and it should be possible to connect the rotor via a further clutch (5) to the input shaft (14) of the transmission (3), the rotor (8) being arranged in a plane radially to the outside of the stator (9). <IMAGE>

Description

Rybrid-Antriebssystem für Fahrzeuge Rybrid drive system for vehicles

Die Erfindung bezieht sich auf ein Rybrid-Antriebssystem für Fahrzeuge, insbesondere Personenkraftfahrzeuge, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a Rybrid drive system for vehicles, in particular passenger vehicles, according to the preamble of claim 1.

Hybrid-Antriebssysteme, die zum Antrieb des Fahrzeugs neben einem herkömmlichen Rubkolben-Verbrennungsmotor noch einen Elektromotor aufweisen, der entweder anstelle des Hubkolben-Verbrennungsmotors oder auch zusätzlich zu diesem zur Erzeugung der Antriebsleistung eines Fahrzeugs herangezogen werden kann, weisen im allgemeinen einen Aufbau auf, bei dem beiderseits des Geschwindigkeitswechselgetriebes je ein Motor angeordnet ist, der je über eine Kupplung mit der Eingangswelle des Getriebes kuppelbar ist. Um das Drehkraftdiagramm des Hubkolben-Verbrennungsmotors zu vergleichmäßigen, weist dieser, wie allgemein bekannt ist, üblicherweise ein mit der Kurbelwelle verbundenes Schwungrad auf.Hybrid propulsion systems that are used to propel the vehicle in addition to one conventional rub-piston internal combustion engine still have an electric motor that either instead of the reciprocating internal combustion engine or in addition to it can be used to generate the drive power of a vehicle generally a structure in which both sides of the speed change gear a motor is arranged, each via a coupling to the input shaft of the Transmission can be coupled. To the torque diagram of the reciprocating internal combustion engine as is generally known, this usually instructs flywheel connected to the crankshaft.

Es ist jedoch auch schon ein Rybrid-Antrieb der im Oberbegriff angegebenen Art bekannt geworden (DE-OS 29 43 554), bei dem der Elektromotor zwischen der Verbrennungskraftmaschine und der Getriebeeingangswelle angeordnet ist und bei dem die Schwungmasse der Verbrennungskraftmaschine integrierter Bestandteil des Elektromotors ist.However, it is already a Rybrid drive of the type specified in the generic term Kind become known (DE-OS 29 43 554), in which the electric motor between the internal combustion engine and the transmission input shaft is arranged and in which the flywheel mass of the internal combustion engine is an integral part of the electric motor.

Die der Erfindung zugrundeliegende Aufgabe besteht nun darin, ein solches Hybrid-Antriebssystem weiterzubilden und dabei eine besonders zweckmäßige Bauform vorzuschlagen, die sich durch gute Wirkung und geringen Bauaufwand auszeichnet.The object of the invention is now to provide a to develop such a hybrid drive system and a particularly useful one To propose a design that is characterized by a good effect and low construction costs.

Die Lösung dieser Aufgabe erfolgt gemäß dem Kennzeichen des Patentanspruchs 1. Danach wird erfindungsgemäß die ohne eigenes Schwungrad ausgeführte Kurbelwelle des Hubkolben-Verbrennungsmotors durch direkte Kupplung mit dem Rotor des Elektromotors verbunden, der zumindest teilweise auf einer gegenüber dem Stator radial äußeren Ebene angeordnet ist. Dies bedingt selbst bei kleinen Abmessungen ein großes Schwungmoment und dabei eine günstige Speicherwirkung.This problem is solved in accordance with the characterizing part of the patent claim 1. Then, according to the invention, the crankshaft designed without its own flywheel is used of the reciprocating internal combustion engine through direct coupling with the rotor of the electric motor connected, the at least partially on a relative to the stator radially outer Level is arranged. This requires a large moment of inertia even with small dimensions and at the same time a favorable storage effect.

Zweckmäßige Ausgestaltungen der Erfindung ergeben sich gemäß den Unteransprüchen und werden anhand der Ausführungsbeispiele der die Erfindung darstellenden Zeichnung näher beschrieben.Appropriate refinements of the invention result from the subclaims and are based on the exemplary embodiments of the drawing illustrating the invention described in more detail.

In den Figuren 1 und 2 sind jeweils für gleiche oder vergleichbare Bauteile die gleichen, gegebenenfalls mit einem Strich versehenen Bezugszeichen verwendet worden. So bezeichnet 1 einen beispielsweise vierzylindrigen Hubkolben-Verbrennungsmotor, 2 einen Elektromotor und 3 ein Getriebe. Die Anordnung ist dabei so getroffen, daß die Kurbelwelle 6 des Hubkolben-Verbrennungsmotors 1 über eine erste Kupplung 4 direkt mit einem an einem Druckplattenträger 7 gehaltenen Rotor 8 des Elektromotors 2 kuppelbar ist, der andererseits über die zweite Kupplung 5 mit der Eingangswelle 14 des Geschwindigkeitswechselgetriebes 3 verbindbar ist.In Figures 1 and 2 are each for the same or comparable Components have the same reference numerals, possibly provided with a prime been used. For example, 1 denotes a four-cylinder reciprocating internal combustion engine, 2 an electric motor and 3 a transmission. The arrangement is made so that the crankshaft 6 of the reciprocating internal combustion engine 1 via a first clutch 4 directly to a rotor 8 of the electric motor held on a pressure plate carrier 7 2 can be coupled, the other hand via the second coupling 5 to the input shaft 14 of the speed change transmission 3 is connectable.

Der Rotor 8 des Elektromotors 2 ist konzentrisch auf einer gegenüber dem Stator 9 des Elektromotors äußeren radialen Ebene angeordnet, um so ein möglichst großes Schwungmoment zu erreichen. Der Stator 9 ist auf einer inneren Radialebene angeordnet und über einen Tragarm 10 an dem feststehenden Gehäuse befestigt.The rotor 8 of the electric motor 2 is concentric on one opposite the stator 9 of the electric motor arranged outer radial plane so as to be as possible to achieve great momentum. The stator 9 is on an inner radial plane arranged and attached to the stationary housing via a support arm 10.

Der Druckplattenträger 7 ist bei der Ausführung nach der Figur 1 einerseits unter Verwendung eines mit einem Lager 11 abgestützten Wellenstumpfes 7a direkt in der Kurbelwelle 6 und andererseits auf der Antriebswelle 14 des Geschwindigkeitswechselgetriebes 3 gelagert, wobei zwischen der Antriebswelle 14 und einem diese konzentrisch übergreifenden Nabenstück 7b des Druckplattenträgers 7 ein Radiallager 12 angeordnet ist. Die Lagerung dieses Nabenstückes könnte übrigens auch auf dem Ralsstück 13a des Getriebegehäuses 13 erfolgen.In the embodiment according to FIG. 1, the printing plate carrier 7 is on the one hand using a stub shaft 7a supported by a bearing 11 directly in the crankshaft 6 and on the other hand on the drive shaft 14 of the speed change gear 3 mounted, with between the drive shaft 14 and a concentrically overlapping it Hub piece 7b of the printing plate carrier 7, a radial bearing 12 is arranged. Warehousing Incidentally, this hub piece could also be placed on the Ralsstück 13a of the gear housing 13 take place.

Mit 15 ist in der Zeichnung die Abtriebswelle des Geschwindigkeitswechselgetriebes 3 bezeichnet, die ein Abtriebsritzel 16 aufweist, das das Tellerrad 17 eines Ausgleichgetriebes 18 antreibt. 19 stellen die beiden, aus dem Ausgleichgetriebe 18 herausragenden Achswellen dar.At 15 is the output shaft of the speed change gear in the drawing 3 denotes, which has an output pinion 16, which is the ring gear 17 of a differential gear 18 drives. 19 represent the two protruding from the differential 18 Axle shafts.

Schließlich ist in Figur 1 mit 20 noch eine beispielsweise mit einer Abhebevorrichtung versehene Bürstenanordnung bezeichnet, über die im elektromotorischen Betrieb dem Rotor 8 elektrischer Strom zuführbar ist. Bei Ausbildung des Rotors 8 als Kurzschlußläufer könnte auf eine solche Bürstenanordnung auch verzichtet werden In der Figur 2 ist in vergrößertem Maßstab ein anderes Ausführungsbeispiel des erfindungsgemäßen Antriebssystems angedeutet, bei dem die Lagerung des Druckplattenträgers 7' beispielhaft in einer anderen Weise ausgeführt ist, indem ein mit dem Druckplattenträger verbundener Lagerhals 36 über Radiallager 39 in einer Lagerhülse 40 des Tragarms 10' konzentrisch innerhalb des Stators 9, abgestützt ist. Gegenüber der Darstellung nach der Figur 1 sind bei dem in der Figur 2 gezeigten Ausführungsbeispiel die beiden Kupplungen 4' und 5' auch nicht direkt nebeneinanderliegend angeordnet, sondern sie sind durch den Elektromotor 2' voneinander getrennt. Die beiden Kupplungen 4' und 5' sowie der Elektromotor 2' stellen dabei eine von einem gemeinsamen Gehäuse 43 umschlossene Baueinheit dar.Finally, in FIG. 1, there is another with 20, for example with a Lifting device provided brush arrangement referred to over the electromotive Operation of the rotor 8 electrical current can be supplied. When training the rotor 8 as a squirrel-cage rotor, such a brush arrangement could also be dispensed with In the figure 2 is another embodiment of the invention on an enlarged scale Drive system indicated, in which the storage of the printing plate carrier 7 'is an example is carried out in another way by a connected to the printing plate carrier Bearing neck 36 concentrically via radial bearings 39 in a bearing sleeve 40 of the support arm 10 ' within the stator 9 is supported. Compared to the representation according to the figure 1 are with the in the embodiment shown in FIG the two clutches 4 'and 5' are also not arranged directly next to one another, but rather they are separated from one another by the electric motor 2 '. The two couplings 4 ' and 5 'and the electric motor 2' represent one of a common housing 43 is an enclosed unit.

Ein diese drei Teile miteinander verbindendes Bauelement wird durch den Druckplattenträger 7' gebildet. Dieser weist zum einen eine Rotortragscheibe 38 auf, an dem der Rotor 8 des Elektromotors 2' auf einer äußeren Radialebene befestigt ist.A structural element that connects these three parts with one another is through the printing plate carrier 7 'formed. On the one hand, this has a rotor support disk 38 on which the rotor 8 of the electric motor 2 'is attached on an outer radial plane is.

Diese Rotortragscheibe 38 wirkt zugleich auch als Lager für eine von einer Druckstange 24 betätigbare Tellerfeder 23 der ersten Kupplung 4'. Die dieser ersten Kupplung 4' zugeordnete Kupplungsscheibe 21 ist mit der Kurbelwelle 6 des Eubkolben-Verbrennungsmotors direkt verbunden. Die Kupplung 4' weist weiter eine an dem Druckplattenträger 7' starr befestigte Druckplatte 37 und eine von der Tellerfeder 21 axial verschiebbare Druckplatte 22 auf.This rotor support disk 38 also acts as a bearing for one of a push rod 24 actuatable plate spring 23 of the first clutch 4 '. The this First clutch 4 'associated clutch disc 21 is connected to the crankshaft 6 of the Eubkolben internal combustion engine directly connected. The coupling 4 'also has a on the pressure plate carrier 7 'rigidly attached pressure plate 37 and one of the plate spring 21 axially displaceable pressure plate 22.

Die Druckstange 24 zur Betätigung der Kupplung 4' ist so ausgebildet, daß sie zentrisch den hohlen Lagerhals 36 des Druckplattenträgea;7' sowie die als Hohlwelle ausgebildete Getriebeeingangswelle 29 durchdringt und mittels eines Drucklagers 27 an ihrem kupplungsfernen Ende betätigbar ist. Mit 28 ist noch ein Führungslager der Druckstange in dem Lagerhals 36 des Druckplattenträgers 7' bezeichnet, während 25 eine Verzahnung darstellt, mit deren Hilfe die mit dem Druckplattenträger 7' umlaufende Druckstange 24 die an dem motorfernen Ende des Getriebegehäuses 13' angeordnete Ölpumpe 26 antreiben kann. Dabei muß die Verzahnung so ausgebildet sein, daß trotz der Aufrechterhaltung der Antriebsverbindung zur Ölpumpe eine axiale Verschiebung der Druckstange zur Betätigung der ersten Kupplung 4' möglich ist.The push rod 24 for actuating the clutch 4 'is designed so that they centrically the hollow bearing neck 36 of the Druckplattenenträgea; 7 'as well as the Hollow shaft formed transmission input shaft 29 penetrates and by means of a thrust bearing 27 can be actuated at its end remote from the coupling. At 28 there is still a lead camp the pressure rod in the bearing neck 36 of the printing plate carrier 7 ', while 25 represents a tooth system, with the help of which the with the printing plate carrier 7 ' circumferential push rod 24 which is arranged at the end of the gear housing 13 'remote from the engine Oil pump 26 can drive. The teeth must be designed so that despite axial displacement to maintain the drive connection to the oil pump the push rod for actuating the first clutch 4 'is possible.

Die zweite Kupplung 5' zwischen dem Rotor 8 des Elektromotors 2' und der Getriebeeingangswelle 29 weist eine auf der Getriebeeingangswelle 29 unverdrehbar gehaltene Kupplungsscheibe 30, eine an dem Druckplattenträger 7' angeordnete Druckplatte 35 sowie eine zweite, an einer Tellerfeder 32 gehaltene Druckplatte 31 auf. Die Tellerfeder 32 ist dabei an einem ringscheibenförmigen Federlager 34 gelagert, das ebenfalls Teil des Druckplattenträgers 7' ist. Zur Betätigung der zweiten Kupplung 5' dient ein Kupplungsausrücklager 33, das in bekannten Weise am radial inneren Umfang der Tellerfeder 32 angreift.The second clutch 5 'between the rotor 8 of the electric motor 2' and the transmission input shaft 29 has a non-rotatable on the transmission input shaft 29 held clutch disc 30, a on the printing plate carrier 7 ' arranged pressure plate 35 and a second, held on a plate spring 32 Pressure plate 31 on. The plate spring 32 is on an annular disk-shaped spring bearing 34 stored, which is also part of the printing plate carrier 7 '. To operate the second clutch 5 'is a clutch release bearing 33, which in a known manner on engages radially inner circumference of the plate spring 32.

Mit 42 ist ein an dem Lagerhals 36 angeordneter und daher mit relativ geringem Durchmesser versehener Kollektor bezeichnet, dem über Bürsten 41 Strom zur Versorgung des Rotors 8 des Elektromotors 2' zuführbar ist. Die Bürsten können dabei mit einer Abhebevorrichtung versehen sein, um bei Abschaltung des elektromotorischen Betriebes keine zusätzliche Reibung oder Verschleiß zu erzeugen.With 42 is arranged on the bearing neck 36 and therefore with relative A collector with a small diameter is referred to, the current via brushes 41 to supply the rotor 8 of the electric motor 2 'can be fed. The brushes can be provided with a lifting device to switch off the electromotive No additional friction or wear and tear during operation.

Die Schwungmasse der schwungradlosen Kurbelwelle 6 des Hubkolben-Verbrennungsmotors 1 wird bei dem erfindungsgemäßen Antriebssystem im wesentlichen durch die Masse des Druckplattenträgers 7' gebildet, der neben den Druckplatten 37 und 35 auch noch den mittleren Lagerhals 36, das Federlager 34 und die Rotortragscheibe 38 aufweist, an der wiederum der Rotor 8 des Elektromotors 2' befestigt ist. Da dieser Rotor 8 auf einer radial äußeren Ebene konzentrisch außerhalb des ringförmigen Stators 9 angeordnet ist, ergibt sich ein relativ großes Schwungaoment, das einerseits eine gute Vergleichmäßigung des relativ ungleichmäßigen Drehkraftdiagramms des Hubkolbenmotors erzeugt, andererseits aber auch nach Ausrücken der beiden Kupplungen 4 und 5 besonders vorteilhaft als Schwungradspeicher zur Speicherung kinetischer Energie des Fahrzeugs wirken kann. Eine solche Betriebsweise ist an sich schon durch die ältere Patentanmeldung P 27 48 697 beschrieben worden, wo das dem Motor zugeordnete Schwungrad zwischen der schwungradlosen Kurbelwelle des Hubkolben-Verbrennungsmotors und der Getriebeeingangswelle angeordnet ist und über je eine Kupplung mit diesen Wellen verbindbar ist.The flywheel mass of the flywheelless crankshaft 6 of the reciprocating internal combustion engine 1 is in the drive system according to the invention essentially by the mass of the printing plate carrier 7 'formed, which in addition to the printing plates 37 and 35 also has the middle bearing neck 36, the spring bearing 34 and the rotor support disk 38, to which in turn the rotor 8 of the electric motor 2 'is attached. Because this rotor 8 on a radially outer plane concentrically outside the annular stator 9 is arranged, there is a relatively large moment of swing, on the one hand a good equalization of the relatively uneven torque diagram of the reciprocating piston engine generated, on the other hand, especially after disengaging the two clutches 4 and 5 advantageous as a flywheel storage device for storing the kinetic energy of the vehicle can work. Such a mode of operation is in itself already through the older patent application P 27 48 697 has been described where the flywheel associated with the engine between the flywheelless crankshaft of the reciprocating internal combustion engine and the transmission input shaft is arranged and can be connected to these shafts via a coupling each.

Bei dem in der Figuren 1 und 2 gezeigten Hybridantriebssystem wird nun dieses Schwungrad im wesentlichen durch den Rotor des wahlweise zum Antrieb des Fahrzeugs zuschaltbaren Elektromotors gebildet. Dieser Elektromotor kann dabei entweder zusätzlich zu dem Hubkolben-Verbrennungsmotor oder aber, beispielsweise bei besonders niedrigen Antriebsleistungen, alternativ anstelle dessen eingesetzt werden, um das Fahrzeug anzutreiben.In the hybrid drive system shown in Figures 1 and 2 Now this flywheel is essentially driven by the rotor of the optional the vehicle's switchable electric motor is formed. This electric motor can do it either in addition to the reciprocating internal combustion engine or, for example in the case of particularly low drive powers, used as an alternative instead to propel the vehicle.

Eine besonders günstige Konstruktion ergibt sich dabei dann, wenn die zur Betätigung der ersten Kupplung vorgesehene, die Getriebeeingangswelle 29 konzentrisch durchdringende Druckstange 24 gleichzeitig eine Verzahnung 25 zum Antrieb der Ölpumpe 26 aufweist. Da diese Druckstange 24 nämlich mit dem Druckplattenträger 7' umläuft, wird auf diese relativ einfache Weise ein Antrieb der Ölpumpe immer dann erreicht, wenn der Druckplattenträger 7' umläuft, Dieser Druckplattenträger läuft aber nicht nur dann um, wenn nach Einrücken der ersten Kupplung 4' der Hubkolben-Verbrennungsmotor im Leerlauf oder nach Einrücken der zweiten Kupplung 5 im Zugbetrieb betrieben wird, sondern auch dann, wenn nach Ausrükken der ersten Kupplung der Elektromotor 2' das Fahrzeug allein antreibt oder aber gar nach Ausrücken der zweiten Kupplung 5' der Druckplattenträger 7' als Schwungspeicher ohne jeden Antrieb von außen umläuft. In dem zuletzt genannten Fall, wenn also nach Ausrücken beider Kupplungen auch der Elektromotor 2' abgeschaltet ist, dient der umlaufende Druckplattenträger 7' als Schwungspeicher, der dann bei ausreichend hoher Drehzahl genügend kinetische Energie zum nachfolgenden Wiederanwerfen des stillgesetzten Hubkolbenmotors 1 bei erneuter Lastanforderung aufweist.A particularly favorable construction results when the transmission input shaft 29 provided for actuating the first clutch concentrically penetrating push rod 24 at the same time a toothing 25 for the drive of the oil pump 26. Since this push rod 24 namely with the pressure plate carrier 7 'revolves, the oil pump is always driven in this relatively simple way then reached when the printing plate carrier 7 'rotates, this printing plate carrier but does not only run around when the reciprocating internal combustion engine after engaging the first clutch 4 ' is operated in idle mode or after engaging the second clutch 5 in pulling mode, but also when, after disengaging the first clutch, the electric motor 2 'das Driving the vehicle alone or even after disengaging the second clutch 5 'of the Printing plate carrier 7 'rotates as a flywheel without any drive from the outside. In the latter case, if so after disengaging both clutches also the Electric motor 2 'is switched off, the rotating printing plate carrier 7' serves as a Flywheel, which then has enough kinetic energy at a sufficiently high speed for the subsequent restarting of the stopped reciprocating piston engine 1 when again Has load requirement.

In der Figur 3 schließlich ist das Regelschema für das erfindungsgemäße Hybrid-Antriebssystem angedeutet, bei dem mit 50 der Verbrennungsmotor, mit 51 der Elektromotor und mit 52 das beiden nachgeschaltete Geschwindigkeitswechselgetriebe bezeichnet ist, das über ein Achsgetriebe 53 die beiden angetriebenen Räder 54 des Fahrzeugs antreibt. Mit 55 sind die nicht angetriebenen Räder des Fahrzeugs angedeutet, von denen hier eine Information über die Raddrehzahl nRad an eine zentrale Steuereinheit 65 weitergeleitet wird. Diese zentrale Steuereinheit 65, die im übrigen die Information über die Raddrehzahl auch von den angetriebenen Rädern beziehen kann, erhält auch Informationen über die Drehzahlen des Verbrennungsmotors nVM' des Elektromotors nEM sowie des Getriebes nG jeweils von den zugeordneten Aggregaten des Antriebssystems. Darüberhinaus werden diesem Steuersystem Informationen über den Istwert der Getriebeübersetzung ist sowie über den Drosselklappenwinkel der in dem Ansaugsystem des Verbrennungsmotors angeordneten Drosselklappe 58 OCDK ist Informationen über die geforderte Last des Fahrzeugs von dem Gaspedal 63 OSGP sowie eine Information über den Zustand des Bremspedals 64 zugeführt. Aus allen diesen Informationen gewinnt die zentrale Steuereinheit 65 Regelimpulse zur Steuerung des Hybrid-Antriebssystems, wobei es sowohl einen Stellmotor 59 zur Verstellung der Drosselklappe 58 des Verbrennungsmotors beaufschlagt, als auch die Feldbeaufschlagung des Elektromotors 51 und die Verstellung der Übersetzung des Geschwindigkeitswechselgetriebes 52 vornehmen kann. Im letzteren Fall kann einem dem Getriebe 52 zugeordneten Stellmotor 62 der Sollwert der Getriebeübersetzung isoll zur Verstellung des beispielsweise aus einem kontinuierlich veränderbaren Kegelscheibenumschlingungsgetriebe bestehenden Getriebes zugeführt werden.Finally, FIG. 3 shows the control scheme for the inventive Hybrid drive system indicated, in which with 50 the internal combustion engine, with 51 the Electric motor and with 52 the two downstream speed change gear is referred to, the two driven wheels 54 of the Vehicle drives. At 55, the vehicle's non-powered wheels are off indicated of which here a piece of information about the wheel speed nRad to a central control unit 65 is forwarded. This central control unit 65, which in the rest of the information can also refer to the driven wheels via the wheel speed, also receives Information about the speeds of the internal combustion engine nVM 'of the electric motor nEM and the gearbox nG each from the associated units of the drive system. In addition, this control system provides information about the actual value of the gear ratio is as well as the throttle valve angle in the intake system of the internal combustion engine arranged throttle valve 58 OCDK is information about the required load of the Vehicle from the accelerator pedal 63 OSGP and information about the state of the brake pedal 64 supplied. The central control unit gains from all this information 65 control pulses for controlling the hybrid drive system, with both a Servomotor 59 is applied to adjust the throttle valve 58 of the internal combustion engine, as well as the application of the field to the electric motor 51 and the adjustment of the translation of the speed change gear 52 can make. In the latter case one can the servomotor 62 assigned to the gear 52 is the setpoint of the gear ratio isoll for adjusting the, for example, continuously changeable Conical pulley belt transmissions are supplied to the existing transmission.

Weiter steuert die zentrale Steuereinheit 65 den Zustand der beiden Kupplungen 56 und 57, indem es die diesen Kupplungen zugeordneten Servomotoren 60 und 61 zur Betätigung mit entsprechenden Steuersignalen beaufschlagt.The central control unit 65 also controls the state of the two Clutches 56 and 57, in that the servomotors 60 associated with these clutches and 61 acted upon by corresponding control signals for actuation.

Abgesehen von den in der Zeichnung gezeigten Ausführungsbeispie len sind noch eine Reihe weiterer Anordnungsmöglichkeiten für die beiden Kupplungen und den Elektromotor denkbar, wobei jeweils der Rotor des Elektromotors den wesentlichen Teil der der Kurbelwelle des Hubkolbenmotors zuzuordnenden Schwungmasse bildet. Zu diesem Zweck ist es dabei auch zweckmäßig, den Rotor auf einem gegenüber dem Stator radial größeren Durchmesser anzuordnen. Anstelle des in den Figuren 1 und 2 angedeuteten Stufenschaltgetriebes könnte auch ein kontinuierlich veränderbares Getriebe, z.B. ein Kegelscheibenumschlingungsgetriebe, verwendet werden.Apart from the Ausführungsbeispie shown in the drawing are a number of other possible arrangements for the two couplings and the electric motor are conceivable, the rotor of the electric motor being the most important in each case Forms part of the flywheel mass to be assigned to the crankshaft of the reciprocating piston engine. For this purpose, it is also useful to place the rotor on one opposite the To arrange stator radially larger diameter. Instead of the in Figures 1 and 2 indicated step shift transmission could also one continuously A variable transmission, e.g. a conical pulley belt transmission, can be used.

Es sind auch andere Konfigurationen des Rotors denkbar, bei denen z.B nicht der ganze Rotor, sondern nur Teile davon radial außerhalb des Stators angeordnet sind, So könnte beispielsweise der rotationssymmetrische Rotor einen C-förmigen Querschnitt aufweisen, wobei ein Schenkel radial innerhalb und ir andere Schenkel radial außerhalb des Stators liegt.Other configurations of the rotor are also conceivable in which E.g. not the whole rotor, but only parts of it radially outside the stator are arranged, for example, the rotationally symmetrical rotor C-shaped cross-section, with one leg radially inward and the other Leg lies radially outside of the stator.
