Vorgesehen ist somit ein Schwungmassenspeicher für ein Kraftfahrzeug, beste- hend aus einem drehbar gelagertem Schwungrad, einem Elektromotor sowie einem Antriebsgleid des Kraftfahrzeuges, wobei Schwungrad und Elektromotor über ein Summiergetriebe auf eine Summenwelle, ein mit dem Antrieb des Fahrzeuges verbundenes Getriebeglied wirken, wobei über das Summiergetriebe das Thus, there is provided a flywheel mass accumulator for a motor vehicle, comprising a rotatably mounted flywheel, an electric motor and a drive track of the motor vehicle, the flywheel and the electric motor acting on a summation shaft, a transmission link connected to the drive of the vehicle via a summing gear Summation gear that

Flywheel from the drive track of the motor vehicle and the electric motor is driven forth and the vehicle, the drive track of the motor vehicle is driven by both the flywheel and the electric motor.
Weiterbildend ist insbesondere vorgesehen: Further education is provided in particular:
- das Summiergetriebe ist als Planetengetriebe ausgebildet. - das Summiergetriebe ist zwischen Schwungrad und der elektrischen Maschine angeordnet. - The summing gear is designed as a planetary gear. - The summation is arranged between the flywheel and the electric machine.
- die Wellen des Schwungrades und der elektrischen Maschine liegen in einer Achse mit dem Summiergetriebe. - die Wellen von Schwungrad und elektrischer Maschine wirken über je ein Ritzel auf je ein nach Art eines Planetenrades getragenes Rad, wobei die Summenwelle durch den Träger der Planeten gebildet ist. Die erfindungsgemäße Lösung besteht aus einem drehbar gelagertem Schwungrad, einem Elektromotor sowie einem An- und Abtriebsgleid des Kraftfahrzeuges. Schwungrad und Elektromotor wirken über ein Summiergetriebe auf ein mit dem Antrieb des Fahrzeuges verbundenes Getriebeglied. Durch das Summiergetriebe wirken zwei Getriebeteile treibend, das dritte Getriebeteil wird durch die beiden anderen getrieben. - The waves of the flywheel and the electric machine are in one axis with the summation. - The waves of flywheel and electric machine act on one pinion on each one carried in the manner of a planet wheel, the sum wave is formed by the carrier of the planet. The solution according to the invention consists of a rotatably mounted flywheel, an electric motor and a drive and Abtriebsgleid of the motor vehicle. Flywheel and electric motor act via a summation on a connected to the drive of the vehicle gear member. By the summing gear act two gear parts driving, the third gear part is driven by the other two.
Erfindungsgemäß ist der kinetische Energiespeicher (Schwungmassenspeicher) mit einer Summierungsvorrichtung, einer ersten Welle eines Summiergetriebes verbunden. Der Elektromotor, die elektrische Maschine ist mit der zweiten Ein- gangswelle des Summiergetriebes verbunden. Über die dritte Getriebewelle (die Ausgangswelle) des Summiergetriebes, über den An- und Abtrieb des Getriebes erfolgt die Kopplung zum Antrieb des Kraftfahrzeuges. Der Elektromotor vermag so den Energieinhalt des Speichers stufenlos zu verstellen und in elektrische Energie zu wandeln. Entsprechend wird der Elektromotor gesteuert. According to the invention, the kinetic energy store (flywheel mass storage) is connected to a summation device, a first shaft of a summing gear. The electric motor, the electric machine, is connected to the second input shaft of the summing gear. About the third gear shaft (the output shaft) of the summation, via the input and output of the transmission is the coupling to the drive of the motor vehicle. The electric motor is thus able to adjust the energy content of the memory infinitely and convert it into electrical energy. Accordingly, the electric motor is controlled.
Durch das Summiergetriebe kann das Schwungrad über den Antrieb des Fahrzeuges (Schubbetrieb) und den Elektromotor getrieben, aufgeladen werden. Bei Stillstand des Elektromotors treibt dann nur der Fahrzeugantrieb, die Verbrennungskraftmaschine das Schwungrad und läd so den Schwungmassenspeicher auf. Letztlich kann der Elektromotor als Generator Energie des Fahrzeuges und/der des Schwungrades in Strom wandeln und so für einen längeren Zeitraum speichern. By the summation, the flywheel can be charged via the drive of the vehicle (push operation) and the electric motor, charged. At standstill of the electric motor then drives only the vehicle drive, the internal combustion engine, the flywheel and so loads the flywheel mass storage. Ultimately, the electric motor as generator can convert energy of the vehicle and / or the flywheel into electricity and thus store it for a longer period of time.
Die Energie des Schwungrades kann mit der Drehzahl des Elektromotors auf den Fahrzeugantrieb geleitet werden. Der Elektromotor steht mit einem Umrichter und einer Steuerung in Verbindung, durch welche die Bestromung entsprechend vorgenommen wird. So ist insbesondere die dem Schwungrad entnehmbare Energie einer Batterie zuführbar, die Schwungradenergie wird somit elektrisch gespeichert und kann zu einem späteren Zeitpunkt zur Beaufschlagung des Elektromotors ge- nutzt werden. Der Elektromotor kann dann den Fahrzeugantrieb direkt unterstüt- zen (elektrischer Zusatzantieb) oder er bewirkt die Aufladung des Schwungrades. Die jeweils vorzunehmende Ansteuerung wird bevorzugt aus der aktuellen Fahrsituation abgeleitet. Der erfindungsgemäße Energiespeicher ist somit gebildet aus einem Schwungrad, einer elektrischen Maschine und einer Summierungsvorrichtung. Die Summie- rungsvorrichtung ist vorzugsweise ein dreiwelliges Getriebe. Ein Glied dient der Ein- und Auskopplung der kinetischen Energie der Schwungmasse, ein Glied dient der Ein- und Auskopplung elektrischer Energie, das dritte Glied ist die Summen- welle, welches mit dem An-/Abtrieb des Energiespeichers verbunden ist. The energy of the flywheel can be directed to the vehicle drive with the speed of the electric motor. The electric motor is connected to a converter and a controller, by means of which the energization is carried out accordingly. Thus, in particular, the energy which can be taken from the flywheel can be supplied to a battery, the flywheel energy is thus stored electrically and can be used at a later time to act on the electric motor. The electric motor can then directly support the vehicle drive. zen (electrical Zusatzantieb) or he causes the charging of the flywheel. The respectively to be performed control is preferably derived from the current driving situation. The energy store according to the invention is thus formed from a flywheel, an electric machine and a summation device. The summation device is preferably a three-shaft transmission. One link serves to couple in and out the kinetic energy of the flywheel, one link serves to couple in and out electrical energy, and the third link is the summed wave, which is connected to the input / output of the energy store.
Vorzugsweise ist das Getriebe als Planetengetriebe ausgeführt. Das Planetengetriebe ist ein Minusgetriebe - Planetengetriebe mit negativer Standübersetzung. Die Drehrichtung des kinetischen Koppelgliedes ist der des elektrischen Koppel- gliedes entgegengesetzt. Preferably, the transmission is designed as a planetary gear. The planetary gear is a negative gear - planetary gear with negative stand ratio. The direction of rotation of the kinetic coupling member is opposite to that of the electrical coupling member.
Die Maximaldrehzahl des Schwungrades wird bei Maximaldrehzahl der Summenwelle und entgegengesetzt gerichteter Maximaldrehzahl der elektrischen Maschine erreicht. The maximum speed of the flywheel is reached at maximum speed of the sum shaft and oppositely directed maximum speed of the electric machine.
Die Summenwelle ist mit einer Getriebeübersetzung, vorzugsweise Stirnradstufe mit einer Triebwelle, dem Fahrzeugtrieb verbunden. Dadurch ist eine stufenlose Verstellung der Drehzahl des Schwungrades und somit des Energieinhaltes des kinetischen Speichers möglich. Insbesondere kann eine Kupplung zur bedarfswei- sen Abkopplung des Energiespeichers kann entfallen. Auch sind Getriebestufen und Schaltvorrichtungen zur Regelung des Ladezustandes des Speichers ebenfalls entbehrlich. The sum shaft is connected to a gear ratio, preferably spur gear with a drive shaft, the vehicle drive. As a result, a continuous adjustment of the speed of the flywheel and thus the energy content of the kinetic memory is possible. In particular, a coupling for disconnecting the energy store as required can be dispensed with. Also gear stages and switching devices for controlling the state of charge of the memory are also unnecessary.
Des Weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung an Hand der Zeichnungen. Furthermore, the explanation of an embodiment of the invention with reference to the drawings.

Pinion R1 of the first shaft W1 and pinion R2 of the second shaft W2 cooperate with a respective planetary gear P1, P2, which are coupled together via a not-shown wheel.
