Dabei dient die elektrische Maschine wahlweise als Anlasser des Verbrennungsmotors, als Ladege­ nerator für die Autobatterie, als aktiver Drehschwin­ gungstilger des Verbrennungsmotors, als generatorische Fahrzeugbremse oder bei abgeschaltetem Verbrennungsmotor als elektrischer Antrieb. Dieses Konzept ist in unter­ schiedlicher Gewichtung einzelner Aspekte in einer Reihe von Patentanmeldungen (ohne Anspruch auf Vollständigkeit), zum Beispiel in DE 33 06 481, DE 44 06 482, DE 44 47 573, DE 44 47 574, DE 195 32 135, DE 195 32 128, DE 195 32 136, DE 195 32 163, DE 195 49 259, DE 195 32 164, DE 195 32 129, 196 31 384 C1 erläutert.The present invention relates to an electric machine ne for coupling to a reciprocating internal combustion engine and a reciprocating internal combustion engine with such an elek machine. The electrical machine is used for this optionally as a starter for the internal combustion engine, as a charger nerator for the car battery, as an active rotating swivel gungstilger the internal combustion engine, as a generator Vehicle brake or when the internal combustion engine is switched off as an electric drive. This concept is in below different weighting of individual aspects in a row patent applications (without claim to completeness), for example in DE 33 06 481, DE 44 06 482, DE 44 47 573, DE 44 47 574, DE 195 32 135, DE 195 32 128, DE 195 32 136, DE 195 32 163, DE 195 49 259, DE 195 32 164, DE 195 32 129, 196 31 384 C1 explained.

Üblicherweise ist dabei die elektrische Maschine mit der Kurbelwelle des Verbrennungsmotors gekoppelt.Usually the electrical machine with the Coupled crankshaft of the internal combustion engine.

Der Erfindung zugrundeliegendes ProblemProblem underlying the invention

Zu erheblichen Problemen führt hierbei jedoch der Umstand, vor allem bei hohen Drehzahlen (etwa 3000 bis 5000 Upm) im Schwingungsdämpfungsbetrieb bzw. zum Ausgleich von Drehun­ gleichförmigkeiten etwa 12 kW an elektrischer Leistung er­ forderlich sind um durch die elektrische Maschine ein Drehmoment von etwa 20 Nm auf die Kurbelwelle des Verbren­ nungsmotors auszuüben. Das kurzzeitige Bereitstellen derart hoher elektrischer Leistungen erfordert außerdem hohe Lei­ tungsquerschnitte für die elektrischen Leitungen, große Energiespeicher und entsprechend leistungsfähige Schalter. However, the fact that especially at high speeds (about 3000 to 5000 rpm) in Vibration damping operation or to compensate for rotation uniformities about 12 kW of electrical power are required to by the electrical machine Torque of about 20 Nm on the crankshaft of the cremation exercise motor. The short-term provision of such high electrical power also requires high lei cross-sections for the electrical lines, large Energy storage and correspondingly powerful switches.  

Erfindungsgemäße LösungSolution according to the invention

Zur Lösung dieser Probleme lehrt die Erfindung eine elek­ trische Maschine zur Ankopplung an einen Hubkolben-Verbren­ nungsmotor, mit einem Rotor der elektrischen Maschine, ei­ nem Stator der elektrischen Maschine, der dazu eingerichtet ist, im wesentlichen fest mit dem Verbrennungsmotor verbun­ den zu werden, und einem Koppelelement, das dazu eingerich­ tet ist, den Rotor mit einer Kurbelwelle des Verbrennungs­ motors torsionsversatzfähig zu verbinden, und einem Lager, das dazu eingerichtet ist, den Rotor auf der Kurbelwelle drehbar zu lagern, wobei das Koppelelement eine solche Tor­ sionsfederkonstante aufweist, daß in Zusammenwirkung mit dem Massenträgheitsmoment des Rotors Dreh-Ungleichförmig­ keiten bei nicht aktiver elektrischer Maschine mit einer bestimmten Resonanzfrequenz des Hubkolben-Verbrennungs­ motors bedämpft werden.To solve these problems, the invention teaches an elek trical machine for coupling to a reciprocating piston combustion voltage motor, with a rotor of the electrical machine, egg nem stator of the electrical machine, which is set up for this is, essentially firmly connected to the internal combustion engine to become, and a coupling element that is set up for this tet is the rotor with a crankshaft of the combustion connect torsionally displaceable, and a bearing, which is set up, the rotor on the crankshaft to be rotatably supported, the coupling element being such a gate sion spring constant that in cooperation with the mass moment of inertia of the rotor non-uniform with an inactive electrical machine certain resonance frequency of the reciprocating piston combustion motors are damped.

Durch dieses, von den bekannten Anordnungen konzeptionell abweichende erfindungsgemäße Konzept ist es möglich, neben der elektrischen (aktiven) Dämpfung durch eine entsprechen­ de Ansteuerung der elektrischem Maschine, mittels einer ge­ eigneten Dimensionierung der Torsionsfederkonstante des Koppelelementes und des Massenträgheitsmoment des Rotors bzw. des Wellenabschnittes eine passive Dämpfung durch die gleichen Komponenten zu erreichen. Dies resultiert in einer insgesamt kompakteren Anordnung, wenn dabei diese Dimensio­ nierung in einer Weise erfolgt, daß elektrisch nur mit ho­ hem Aufwand bedämpfbare Schwingungen bzw. Dreh-Ungleichför­ migkeiten auf diese (mechanische) Weise bedämpft werden, während elektrisch mit geringerem Aufwand bedämpfbare Schwingungen mittels der elektrischen Maschine bedämpft werden. Die erfindungsgemäße Anordnung macht sich dabei den ohnehin vorhandenen Rotor zunutze, so daß keine zusätzliche Masse vorzusehen ist.Through this, conceptually from the known arrangements deviating concept according to the invention, it is possible in addition to the electrical (active) damping by a de Control of the electrical machine by means of a ge suitable dimensioning of the torsion spring constant of Coupling element and the mass moment of inertia of the rotor or the shaft section a passive damping by to achieve the same components. This results in one overall more compact arrangement when doing this dimension nation in such a way that electrically only with ho Hem effort dampable vibrations or rotational unequal are dampened in this (mechanical) way, while electrically dampable with less effort Vibrations damped by the electrical machine become. The arrangement according to the invention makes the use existing rotor anyway, so that no additional Mass is to be provided.

Dabei kann der Rotor durch ein Kugel-, Rollen-, Nadel-, oder Gleitlager über ein Gehäuse der elektrischen Maschine mit dem Stator verbunden sein. The rotor can be replaced by a ball, roller, needle, or plain bearings via a housing of the electrical machine be connected to the stator.  

Vorzugsweise ist das Koppelelement ein Hartgummi-Element. Es ist jedoch auch möglich, das Koppelelement durch ein an­ deres Bauteil oder eine andere Baugruppe mit insoweit ver­ gleichbaren Eigenschaften zu realisieren.The coupling element is preferably a hard rubber element. However, it is also possible to use a coupling element veres component or another assembly with insofar to realize similar properties.

Insbesondere betrifft die Erfindung eine elektrische Ma­ schine, die an der dem Schalt- oder Automatikgetriebe abge­ wandten Seite der Motorblocks des Verbrennungsmotors an­ geordnet.In particular, the invention relates to an electrical Ma machine that abge on the manual or automatic transmission applied side of the engine blocks of the internal combustion engine orderly.

Mit besonders großem Effekt kann die Erfindung eingesetzt werden, wenn die elektrische Maschine ein Asynchronmotor ist.The invention can be used with a particularly great effect if the electrical machine is an asynchronous motor is.

Schließlich betrifft die Erfindung einen Verbrennungsmotor mit einer angebauten elektrischen Maschine, mit einem Sta­ tor der elektrischen Maschine, der im wesentlichen fest mit dem Verbrennungsmotor verbunden ist, und einem Rotor der elektrischen Maschine, der mit einer Kurbelwelle des Ver­ brennungsmotors durch ein Koppelelement verbunden ist, wo­ bei das Koppelelement den Rotor mit der Kurbelwelle torsi­ onsversatzfähig verbindet, und wobei das Koppelelement eine solche Torsionsfederkonstante aufweist, daß in Zusammenwir­ kung mit dem Massenträgheitsmoment des Rotors Dreh- Ungleichförmigkeiten bei nicht aktiver elektrischer Maschi­ ne mit einer bestimmten Resonanzfrequenz des Hubkolben- Verbrennungsmotors bedämpft werden.Finally, the invention relates to an internal combustion engine with an attached electrical machine, with a sta gate of the electrical machine, which is essentially fixed with the internal combustion engine is connected, and a rotor electrical machine with a crankshaft of the Ver internal combustion engine is connected by a coupling element where in the coupling element the rotor with the crankshaft torsi onsversatzbaren connects, and wherein the coupling element a has such a torsion spring constant that in cooperation with the mass moment of inertia of the rotor Irregularities when the electrical machine is not active ne with a certain resonance frequency of the reciprocating Internal combustion engine are damped.

Weitere Eigenschaften, Merkmale, Vorteile und Abwandlungen werden anhand der nachstehenden Beschreibung der Zeichnung deutlich, in denen Ausführungsbeispiele der Erfindung dar­ gestellt sind.Other properties, features, advantages and modifications are based on the description of the drawing below clearly, in which embodiments of the invention are posed.

Beschreibung einer bevorzugten AusführungsformDescription of a preferred embodiment

In der einzigen Figur ist eine Ausführungsform der Erfindung schematisch gezeigt, wobei an der dem Getriebe 12 abgewand­ ten Seite eines (lediglich teilweise veranschaulichten) Verbrennungsmotors 10 eine elektrische Maschine im Form ei­ ner Asynchronmaschine 14 vorgesehen ist. Dabei ist die Dar­ stellung keineswegs maßstäblich. Vielmehr ist in der Regel der Verbrennungsmotor 10 erheblich voluminöser als die elektrische Maschine 14.In the single figure, an embodiment of the invention is shown schematically, an electrical machine in the form of an asynchronous machine 14 being provided on the side of a combustion engine 10 (only partially illustrated) facing away from the transmission 12 . The representation is by no means to scale. Rather, the internal combustion engine 10 is generally considerably more voluminous than the electrical machine 14 .

Die elektrische Maschine 14 hat einen Rotor 16, der über ein Koppelelement 20 mit einem freien Ende 18 der Kurbel­ welle 22 verbunden ist. Durch das Koppelelement 20 in Form eines Hartgummi-Elementes wird der Rotor 16 mit der Kurbel­ welle 22 des Verbrennungsmotors 10 in einer Weise verbun­ den, daß eine Torsion (allerdings nur in sehr geringem Maß) der Kurbelwelle 22 des Verbrennungsmotors 10 bzw. dem Wel­ lenabschnitt 18 gegenüber dem darauf sitzenden Rotor 16 möglich ist. Der Rotor 16 ist zusätzlich durch ein Axial­ rollenlager 32 in Umfangsrichtung des Rotors 16 drehbar auf diesem gelagert.The electrical machine 14 has a rotor 16 which is connected via a coupling element 20 to a free end 18 of the crank shaft 22 . By the coupling element 20 in the form of a hard rubber element of the rotor 16 to the crank shaft 22 of the engine 10 in a manner-jointed, that a torsion (but only in a very small extent) of the crankshaft 22 of the engine 10 or the Wel lenabschnitt 18 compared to the rotor 16 sitting thereon is possible. The rotor 16 is additionally rotatably supported by an axial roller bearing 32 in the circumferential direction of the rotor 16 .

Ein Stator 26 der elektrischen Maschine 14 ist fest in ei­ nem Gehäuse 28 aufgenommen. Das Gehäuse 26 weist einen Flansch 30 auf, mit dem die elektrische Maschine 14 fest mit dem Verbrennungsmotor 10 verbunden (verschraubt) ist.A stator 26 of the electrical machine 14 is firmly accommodated in a housing 28 . The housing 26 has a flange 30 with which the electrical machine 14 is firmly connected (screwed) to the internal combustion engine 10 .

Durch geeignete Dimensionierung des Koppelelementes 20 im Verhältnis zu dem Massenträgheitsmoment des Rotors 16 und des Wellenabschnittes 18 wird eine Resonanzfrequenz des Verbrennungsmotors mechanisch bedämpft.A suitable dimensioning of the coupling element 20 in relation to the mass moment of inertia of the rotor 16 and the shaft section 18 mechanically dampens a resonance frequency of the internal combustion engine.

Da insoweit eine separate mechanische Bedämpfungseinrich­ tung nicht erforderlich ist, während gleichzeitig die Di­ mensionierung der elektrischen Maschine, deren Ansteuere­ lektronik etc. kleiner ausfallen kann, wird insgesamt eine kompakter bauende Gesamtanordnung erreicht.As a separate mechanical damping device tion is not required, while the Di dimensioning of the electrical machine and its controls electronics etc. can be smaller, will be a total compact overall construction achieved.
