Rotationskolben-Verbrennungskraftmaschine mit elektrischem Antrieb am Rotationskolben Rotary piston internal combustion engine with electric drive on rotary piston
Die vorliegende Erfindung betrifft eine Rotationskolben-Ver- brennungskraftmaschine, The present invention relates to a rotary piston internal combustion engine,
- wobei die Rotationskolben-Verbrennungskraftmaschine mindes¬ tens einen Rotationskolben aufweist, der in einem Kolbenge- häuse der Verbrennungskraftmaschine angeordnet ist, - wherein the rotary piston internal combustion engine Minim ¬ least comprises a rotary piston, the housing in a piston speed of the internal combustion engine is disposed,
- wobei der Rotationskolben um eine Rotationsachse rotierbar ist,  - wherein the rotary piston is rotatable about an axis of rotation,
- wobei der Rotationskolben Außenflächen aufweist, die an parallel zur Rotationsachse verlaufenden Grenzkanten unter Bildung eines jeweiligen Grenzwinkels aneinander angrenzen, - wherein the rotary piston has outer surfaces which adjoin one another at boundary edges extending parallel to the axis of rotation, forming a respective limiting angle,
- wobei das Kolbengehäuse einen Einlassbereich zum Zuführen eines Frischgases, einen Zündbereich zum Zünden des Frischgases nebst nachfolgendem Verbrennen zu einem Abgas und einen Auslassbereich zum Abführen des Abgases aufweist, - wherein the piston housing has an inlet region for supplying a fresh gas, an ignition region for igniting the fresh gas and subsequent combustion to an exhaust gas and an outlet region for discharging the exhaust gas,
- wobei die Grenzkanten den Einlassbereich, den Zündbereich und den Auslassbereich gegeneinander abdichten. - The boundary edges seal the inlet area, the ignition area and the outlet area against each other.
Rotationskolben-Verbrennungskraftmaschinen können als Drehkolbenmotor oder als Kreiskolbenmotor ausgebildet sein. Ins- besondere Kreiskolbenmotoren sind allgemein bekannt. Insbe¬ sondere arbeitet jeder übliche Wankelmotor nach diesem Prinzip . Rotary piston internal combustion engines can be designed as a rotary piston engine or as a rotary piston engine. In particular rotary piston engines are well known. In particular ¬ sondere any conventional Wankel engine operates according to this principle.
Im Stand der Technik werden zur Erzeugung elektrischer Ener- gie oftmals elektrische Maschinen mechanisch mit Verbrennungskraftmaschinen verbunden. Aufgrund dieser funktionalen Trennung ergeben sich mechanische Verluste beispielsweise durch Reibung, durch Umsetzungsgetriebe und dergleichen mehr. Weiterhin ergibt sich ein relativ großer Bauraum. In the prior art, electrical machines are often mechanically connected to internal combustion engines for generating electrical energy. As a result of this functional separation, mechanical losses, for example due to friction, through gearboxes and the like, result more. Furthermore, there is a relatively large space.
Zur Erreichung einer hohen Leistungsdichte bei kompakter Bauweise ist es von Vorteil, die elektrische Maschine in die Verbrennungskraftmaschine zu integrieren. Die Aufgabe der vorliegenden Erfindung besteht darin, eine elektrische Maschine in eine Rotationskolben-Verbrennungs- kraftmaschine der eingangs genannten Art zu integrieren. Die Aufgabe wird durch eine Rotationskolben-Verbrennungs- kraftmaschine mit den Merkmalen des Anspruchs 1 gelöst. Vor¬ teilhafte Ausgestaltungen der erfindungsgemäßen Rotationskol- ben-Verbrennungskraftmaschine sind Gegenstand der abhängigen Ansprüche 2 bis 6. To achieve a high power density in a compact design, it is advantageous to integrate the electric machine in the internal combustion engine. The object of the present invention is to integrate an electric machine in a rotary piston internal combustion engine of the type mentioned. The object is achieved by a rotary piston internal combustion engine having the features of claim 1. Before ¬ some embodiments of the Rotationskol- ben-combustion engine according to the invention are subject of the dependent claims 2 to. 6
Erfindungsgemäß wird eine Rotationskolben-Verbrennungskraft¬ maschine der eingangs genannten Art dadurch ausgestaltet,According to the invention, a rotary piston internal combustion ¬ machine of the type mentioned is configured by
- dass im Bereich der Grenzkanten der Rotor einer elektrischen Maschine angeordnet ist, that the rotor of an electrical machine is arranged in the region of the boundary edges,
- dass am Kolbengehäuse der Stator der elektrischen Maschine angeordnet ist, - That the stator of the electric machine is arranged on the piston housing,
- dass der Stator der elektrischen Maschine mit dem Rotor der elektrischen Maschine elektrisch zusammenwirkt und  - That the stator of the electric machine electrically interacts with the rotor of the electric machine and
- dass der Stator der elektrischen Maschine zur bidirektiona- len Übertragung elektrischer Energie mit einer Umrichtereinheit verbunden ist.  - That the stator of the electric machine for bidirectional transmission of electrical energy is connected to a converter unit.
Durch diese Vorgehensweise kann die elektrische Maschine in die Rotationskolben-Verbrennungskraftmaschine integriert wer- den. By this procedure, the electric machine can be integrated into the rotary piston internal combustion engine.
In einer bevorzugten Ausgestaltung der erfindungsgemäßen Verbrennungskraftmaschine ist der Stator an einer Außenseite des Kolbengehäuses angeordnet. Insbesondere in diesem Fall be- steht das Kolbengehäuse zumindest in demjenigen Bereich, der zwischen dem Stator und dem Rotor der elektrischen Maschine angeordnet ist, vorzugsweise aus einem nicht magnetisierbaren Material . Es kann in Einzelfällen möglich sein, dass der Stator sich von der Rotationsachse ausgesehen über einen Vollkreis erstreckt, also vollständig um die Rotationsachse herum. In der Regel erstreckt der Stator sich jedoch nur über einen Teilum- fang. Der Teilumfang kann insbesondere mit dem Bereich zwischen dem Einlassbereich und dem Zündbereich korrespondieren. In a preferred embodiment of the internal combustion engine according to the invention, the stator is arranged on an outer side of the piston housing. In particular in this case, the piston housing is preferably made of a non-magnetizable material, at least in that region which is arranged between the stator and the rotor of the electric machine. It may be possible in individual cases that the stator extends from the axis of rotation over a full circle, ie completely around the axis of rotation. As a rule, however, the stator only extends over a partial fang. The partial circumference may in particular correspond to the region between the inlet region and the ignition region.
Vorzugsweise ist dem Rotationskolben ein Lagegeber zugeord- net, mittels dessen eine Drehstellung des Rotationskolbens erfasst wird. In diesem Fall kann die Drehstellung einer Steuereinrichtung für die Umrichtereinheit zugeführt werden und kann die Steuereinrichtung die Umrichtereinheit in Abhängigkeit von der Drehstellung des Rotationskolbens ansteuern. Preferably, a rotary encoder is assigned to the rotary piston, by means of which a rotational position of the rotary piston is detected. In this case, the rotational position of a control device for the inverter unit can be supplied and the control device can drive the inverter unit in dependence on the rotational position of the rotary piston.
Die oben beschriebenen Eigenschaften, Merkmale und Vorteile dieser Erfindung sowie die Art und Weise, wie diese erreicht werden, werden klarer und deutlicher verständlich im Zusammenhang mit der folgenden Beschreibung der Ausführungsbei- spiele, die in Verbindung mit den Zeichnungen näher erläutert werden. Hierbei zeigen in schematischer Darstellung: The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following description of the embodiments which will be described in detail in conjunction with the drawings. Here are shown in a schematic representation:

Gemäß FIG 1 weist eine Rotationskolben-Verbrennungskraft¬ maschine einen Rotationskolben 1 auf. Der Rotationskolben 1 kann alternativ als Drehkolben (FIG 1) oder als Kreiskolben (FIG 2) ausgebildet sein. Im erstgenannten Fall rotiert der Rotationskolben 1 um eine ruhende Rotationsachse 2. Im letzt¬ genannten Fall rotiert der Rotationskolben 1 um eine Rotationsachse 2, die ihrerseits um eine Zentralachse 3 rotiert. In der Praxis wird meist der letztgenannte Fall realisiert sein. In beiden Fällen ist der Rotationskolben 1 um die Rotation- sachse 2 rotierbar. Der Rotationskolben 1 ist weiterhin in beiden Fällen in einem Kolbengehäuse 4 der Verbrennungskraft¬ maschine angeordnet. As shown in FIG 1 has a rotary piston internal combustion engine ¬ a rotary piston. 1 The rotary piston 1 can alternatively be designed as a rotary piston (FIG. 1) or as a rotary piston (FIG. 2). In the former case, the rotary piston 1 rotates about a stationary rotation axis 2. In the last ¬ mentioned case, the rotary piston 1 rotates about a rotation axis 2, which in turn rotates about a central axis 3. In practice, the latter case will usually be realized. In both cases, the rotary piston 1 is rotatable about the rotation axis 2. The rotary piston 1 is further arranged in both cases in a piston housing 4 of the internal combustion ¬ machine.
Der Rotationskolben 1 weist Außenflächen 5 auf. Die Außenflä- chen 5 sind in der Regel entsprechend der Darstellung in FIG 1 und 2 gewölbt. Die Außenflächen 5 grenzen an Grenzkanten 6 aneinander an. Die Grenzkanten 6 verlaufen parallel zur Rota- tionsachse 2. Die Außenflächen 5 bilden an den Grenzkanten 6 einen jeweiligen Grenzwinkel miteinander. The rotary piston 1 has outer surfaces 5. The outer surfaces 5 are generally arched as shown in FIGS. 1 and 2. The outer surfaces 5 adjoin one another at boundary edges 6. The boundary edges 6 run parallel to the Rota tion axis 2. The outer surfaces 5 form at the boundary edges 6 a respective critical angle with each other.
Das Kolbengehäuse 4 weist einen Einlassbereich 7 auf, über den ein Frischgas 8 in den Zwischenraum zwischen der zu diesem Zeitpunkt im Einlassbereich 7 befindlichen Außenfläche 5 und das Kolbengehäuse 4 eingeführt wird. Beim Rotieren des Rotationskolbens 1 wird das eingeführte Frischgas 8 kompri¬ miert. Wenn die entsprechende Außenfläche 5 sich in einem Zündbereich 9 des Kolbengehäuses 4 befindet, wird das Frisch¬ gas 8 mittels einer entsprechenden Zündeinrichtung 9' - beispielsweise Zündkerzen 9' - gezündet. Das Frischgas 8 ver¬ brennt dadurch und wird zu Abgas 10. Beim weiteren Rotieren des Rotationskolbens 1 wird das Abgas 10 an einem Auslassbe- reich 11 des Kolbengehäuses 4 abgeführt. The piston housing 4 has an inlet region 7, via which a fresh gas 8 is introduced into the intermediate space between the outer surface 5 located at this time in the inlet region 7 and the piston housing 4. When rotating the rotary piston 1, the introduced fresh gas 8 is Kompri ¬ mized. If the corresponding outer surface is in an ignition region of the piston housing 9 4 5, the fresh gas ¬ 8 by means of an appropriate ignition device 9 '- for example, spark plugs 9' - ignited. The fresh gas 8 ver ¬ characterized burns and becomes exhaust gas 10. During further rotation of the rotary piston 1, the exhaust gas 10 is high in a discharged Auslassbe- 11 of the piston housing. 4
Die Grenzkanten 6 dichten den Einlassbereich 7, den Zündbereich 9 und den Auslassbereich 11 gegeneinander ab. Soweit bisher beschrieben, entsprechen Aufbau und Wirkungsweise der beschriebenen Rotationskolben-Verbrennungskraftma¬ schine dem Aufbau und der Wirkungsweise einer üblichen Rota- tionskolben-Verbrennungskraftmaschine, beispielsweise eines so genannten Wankelmotors. Erfindungsgemäß ist im Bereich der Grenzkanten 6 der Rotor 12 einer elektrischen Maschine angeordnet . The boundary edges 6 seal the inlet region 7, the ignition region 9 and the outlet region 11 from each other. As so far described, correspond to structure and operation of the described rotary piston Verbrennungskraftma ¬ machine the construction and operation of a conventional rotary piston internal combustion engine such as a Wankel engine as above. According to the invention, the rotor 12 of an electric machine is arranged in the region of the boundary edges 6.
Der Rotor 12 kann beispielsweise entsprechend der Darstellung in FIG 1 und 2 Permanentmagnete 13 umfassen. In diesem Fall ist die elektrische Maschine als permanent erregte Synchron¬ maschine ausgebildet. Alternativ könnte der Rotor 12 eine Wicklung aufweisen. In diesem Fall wäre die elektrische Maschine als elektrisch erregte Synchronmaschine ausgebildet. Wiederum alternativ könnte die elektrische Maschine bei- spielsweise als Asynchronmaschine ausgebildet sein. Auch an¬ dere Ausgestaltungen sind möglich. Am Kolbengehäuse 4 ist ein Stator 14 der elektrischen Maschine angeordnet. Der Stator 14 ist vorzugsweise soweit radial innen wie möglich angeordnet. Der Stator 14 der elektrischen Maschine ist zur bidirektionalen Übertragung elektrischer Energie mit einer Umrichtereinheit 15 verbunden. Die elektri¬ sche Maschine wirkt - je nach Ansteuerzustand der Umrichter¬ einheit 15 - als Generator oder als Motor. For example, the rotor 12 may include permanent magnets 13 as shown in FIGS. In this case, the electric machine is designed as a permanently excited synchronous ¬ machine. Alternatively, the rotor 12 could have a winding. In this case, the electric machine would be designed as an electrically excited synchronous machine. Again, alternatively, the electric machine could be designed, for example, as an asynchronous machine. Also ¬ to other embodiments are possible. On the piston housing 4, a stator 14 of the electric machine is arranged. The stator 14 is preferably arranged as far radially inward as possible. The stator 14 of the electric machine is connected to a converter unit 15 for the bidirectional transmission of electrical energy. The electric ¬ cal machine acts - depending on the driving state of the inverter ¬ unit 15 - as a generator or as a motor.
Gemäß FIG 1 und 2 ist der Stator 14 vorzugsweise an einer Au- ßenseite des Kolbengehäuses 4 angeordnet. Der Stator 14 kann alternativ an der Außenseite des Kolbengehäuses 4 in das Kol¬ bengehäuse 4 integriert sein oder außen am Kolbengehäuse 4 angeordnet sein. Das Kolbengehäuse 4 befindet sich also zwi¬ schen dem Rotor 12 und dem Stator 14, d.h. im so genannten Luftspalt. Vorzugsweise besteht daher das Kolbengehäuse 4 zu¬ mindest in demjenigen Bereich, der zwischen dem Stator 14 und dem Rotor 12 der elektrischen Maschine angeordnet ist, aus einem nicht magnetisierbaren Material. Ein Beispiel eines ge¬ eigneten Materials ist Aluminium. Alternativ kommen tempera- turfeste Kunststoffe infrage, beispielsweise Polyimide. According to FIGS. 1 and 2, the stator 14 is preferably arranged on an outer side of the piston housing 4. The stator 14 may alternatively be integrated on the outside of the piston housing 4 in the Kol ¬ bengehäuse 4 or be arranged on the outside of the piston housing 4. Thus, the piston housing 4 is located Zvi ¬ rule the rotor 12 and the stator 14, that is, the so-called air gap. Preferably, therefore, the piston housing 4 is made of a non-magnetizable material for ¬ at least in that area which is arranged between the stator 14 and the rotor 12 of the electric machine. An example of a suitable material is aluminum ¬ ge. Alternatively, temperature-resistant plastics are suitable, for example polyimides.
Der Stator 14 erstreckt sich von der Rotationsachse 2 aus ge¬ sehen meist nicht über einen Vollkreis, sondern nur über einen Teilumfang ß. Der Teilumfang ß liegt in der Regel zwi- sehen 90° und 180°, beispielsweise bei ca. 100° bis 120°. Der Teilumfang ß kann insbesondere mit dem Bereich zwischen dem Einlassbereich 7 und dem Zündbereich 9 korrespondieren. The stator 14 is not extending from the axis of rotation 2 of Ge ¬ see usually over a full circle, but only over a partial circumference ß. The partial circumference β is usually between 90 ° and 180 °, for example at about 100 ° to 120 °. The partial circumference β can correspond in particular to the region between the inlet region 7 and the ignition region 9.
Zur ordnungsgemäßen Ansteuerung der Umrichtereinheit 15 ist eine Steuereinrichtung 16 vorhanden. Um die Umrichtereinheit 15 ordnungsgemäß ansteuern zu können, ist es jedoch zusätzlich oftmals erforderlich, dass der Steuereinrichtung 16 (unter anderem) eine Drehstellung φ des Rotationskolbens 1 be¬ kannt ist. Vorzugsweise ist dem Rotationskolben 1 daher ein Lagegeber 17 zugeordnet, mittels dessen die Drehstellung φ erfasst wird. Die erfasste Drehstellung φ wird in diesem Fall der Steuereinrichtung 16 zugeführt. Die Steuereinrichtung 16 ist daher in der Lage, die Umrichtereinheit 15 in Abhängig- keit von der Drehstellung φ des Rotationskolbens 1 anzu¬ steuern. Die Drehstellung φ kann unter Umständen auf modulo n x 360° (= n x 2n) mit n > 1 bezogen sein. In manchen Fällen reicht eine Ermittlung modulo 360° (= 2n) . For proper control of the inverter unit 15, a control device 16 is present. However, to the inverter unit to be able to control properly 15, it is often necessary, in addition, that the controller 16 (among others) a rotational position is known be ¬ φ of the rotary piston. 1 Preferably, the rotary piston 1 is therefore associated with a position sensor 17, by means of which the rotational position φ is detected. The detected rotational position φ is supplied to the control device 16 in this case. The control device 16 is therefore able to condition the converter unit 15 in dependence speed of the rotational position φ of the rotary piston 1 to ¬ control. The rotational position φ may be related to modulo nx 360 ° (= nx 2n) with n> 1 under certain circumstances. In some cases, a determination modulo 360 ° (= 2n).
Durch die Integration der elektrischen Maschine in die Verbrennungskraftmaschine kann auf einfache Weise zeit- und/oder stellungsabhängig auf den Rotationskolben 1 gezielt ein Drehmoment aufgebracht werden. Mittels der Steuereinrichtung 16 können - im Rahmen der Leistungsfähigkeit der elektrischen Maschine und der Umrichtereinheit 15 - zeitvariable Drehmo¬ mente vorgegeben werden. Man erhält also eine aktive Ein¬ griffsmöglichkeit auf die Bewegung des Rotationskolbens 1. Die elektrische Maschine und die Umrichtereinheit 15 können um nach Bedarf dimensioniert werden. Es ist möglich, dass sie - ähnlich des elektrischen Anlassers oder der Lichtmaschine bei einem Automotor - nur unterstützend wirken. Alternativ ist es möglich, die elektrische Maschine und die Umrichter- einheit 15 derart zu dimensionieren, dass nahezu die gesamte von der Verbrennungskraftmaschine zur Verfügung gestellte me¬ chanische Energie elektrische Energie umgewandelt wird. By integrating the electric machine in the internal combustion engine can be applied in a simple manner time and / or position-dependent on the rotary piston 1 selectively a torque. By means of the control device 16 can - time-varying Drehmo ¬ elements are given - in the context of performance of the electrical machine and the converter 15 °. We thus obtain an active ¬ A possibility of resorting to the movement of the rotary piston 1. The electrical machine and the inverter unit 15 can be dimensioned to as needed. It is possible that they - similar to the electric starter or the alternator in a car engine - only supportive. Alternatively, it is possible to dimension the electric machine and the inverter unit 15 in such a way that almost all supplied by the internal combustion engine available me ¬ chanical energy is converted electrical energy.
Die erfindungsgemäße Verbrennungskraftmaschine wurde obenste- hend in Verbindung mit einem einzelnen Rotationskolben 1 erläutert. Sie ist jedoch ohne weiteres auch bei Verbrennungs¬ kraftmaschinen mit mehreren Rotationskolben 1 anwendbar. Die Rotationskolben 1 können in diesem Fall insbesondere regelmäßig gegeneinander um die Rotationsachse 2 verdreht sein. Da- durch kann insbesondere auf einfache Weise eine gleichmäßige Erzeugung elektrischer Energie erreicht werden. The internal combustion engine according to the invention has been explained above in connection with a single rotary piston 1. However, it is readily applicable to internal combustion engines ¬ with multiple rotary piston 1. The rotary pistons 1 can be rotated in this case in particular regularly against each other about the rotation axis 2. As a result, a uniform generation of electrical energy can be achieved in a simple manner.
Die vorliegende Erfindung weist viele Vorteile auf. Insbeson¬ dere ergibt sich eine sehr kompakte Verbrennungskraftmaschine mit integrierter elektrischer Maschine. The present invention has many advantages. In particular ¬ der results in a very compact internal combustion engine with integrated electric machine.
Die erfindungsgemäße Verbrennungskraftmaschine ist nahezu universell einsetzbar, beispielsweise als Antrieb für Land- oder Wasserfahrzeuge aller Art, als stationäres Notstromag¬ gregat und dergleichen mehr. The internal combustion engine according to the invention can be used almost universally, for example as a drive for agricultural vehicles. or watercraft of all kinds, as a stationary Notstromag ¬ gregat and the like.
