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.
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.
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.

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.

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 .
