Abstract
Description
Die Erfindung betrifft eine Hybrid-Antriebsvorrichtung für Kraftfahrzeuge gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a hybrid drive device for motor vehicles according to the preamble of claim 1.
Hybridantriebsvorrichtungen für Kraftfahrzeuge mit einer Brennkraftmaschine und einer Elektromaschine sind vielfach bekannt. Dabei kann die Elektromaschine im Antriebsstrang montiert werden und während eines Rekuperationsvorgangs als Generator bzw. während des elektrischen Fahrbetriebs als Antriebsmotor dienen. Idealerweise wird die Elektromaschine an einem drehenden Teil im Antriebsstrang angebunden, von dem aus sie rekupieren oder boosten kann. Ist die Elektromaschine an der Getriebeeingangswelle montiert, so wird der Kraftfluss zwischen der Elektromaschine und den Rädern immer wieder durch Kuppeln und/oder Schalten unterbrochen. Dieses kann zwar durch Automatikgetriebe oder intelligente Steuerungen teilweise kompensiert, jedoch nicht vollständig beseitigt werden.Hybrid drive devices for motor vehicles with an internal combustion engine and an electric machine are widely known. In this case, the electric machine can be mounted in the drive train and serve as a generator or during the electric driving operation as a drive motor during a Rekuperationsvorgangs. Ideally, the electric machine is connected to a rotating part in the drive train, from which it can recuperate or boost. If the electric machine is mounted on the transmission input shaft, the power flow between the electric machine and the wheels is interrupted again and again by coupling and / or switching. Although this can be partially compensated by automatic transmissions or intelligent controls, it can not be completely eliminated.
Die Elektromaschine kann dabei auf die Eingangswelle des Geschwindigkeits-Wechselgetriebes wirken und dadurch zugleich als Startermotor zum Inbetriebsetzen der Brennkraftmaschine dienen. Zudem können Übersetzungsstufen des Wechselgetriebes auch bei elektromotorischem Betrieb genutzt werden. Wirkt die Elektromaschine unmittelbar auf die Abtriebswelle des Wechselgetriebes, so ist ein weitgehend ohne Zugkraftunterbrechungen realisierbarer, komfortabler Fahrbetrieb möglich, bei dem die Massenträgheit der elektrischen Einheit sich zudem nicht nachteilig auf die Schaltvorgänge im Wechselgetriebe auswirken kann. Boostbetrieb und Rekuperationsbetrieb sind relativ einfach steuerbar. Allerdings kann die Brennkraftmaschine nicht über die Elektromaschine gestartet werden.The electric machine can act on the input shaft of the speed change gear and thereby also serve as a starter motor for putting the engine. In addition, gear ratios of the gearbox can also be used in electric motor operation. If the electric machine acts directly on the output shaft of the change-speed gearbox, then a comfortable driving mode that is feasible without traction interruptions is possible, in which the mass inertia of the electrical unit can not adversely affect the shifting processes in the change gearbox. Boost operation and recuperation operation are relatively easy to control. However, the internal combustion engine can not be started via the electric machine.
Durch die
Aufgabe der Erfindung ist es, eine Hybrid-Antriebsvorrichtung vorzuschlagen, die bei einem getriebetechnisch relativ einfachem Aufbau und mit geringem steuerungstechnischen Aufwand einen komfortablen Fahrbetrieb in allen für einen Hybridantrieb zweckmäßigen Betriebsarten einerseits und ein Starten der Brennkraftmaschine über die Elektromaschine andererseits ermöglicht.The object of the invention is to propose a hybrid drive device that allows a comfortable driving in all for a hybrid drive appropriate modes on the one hand and starting the engine via the electric machine on the other hand in a relatively simple design and with little technical control effort.
Die Lösung dieser Aufgabe gelingt erfindungsgemäß mit den Merkmalen des Patentanspruches 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angeführt.The solution of this object is achieved according to the invention with the features of claim 1. Advantageous developments of the invention are set forth in the dependent claims.
Erfindungsgemäß wird vorgeschlagen, dass im Kraftfluss zur Eingangswelle des Wechselgetriebes und hinter der ersten Kupplung und dem Übersetzungstrieb eine dritte Kupplung eingeschaltet ist, die im geöffneten Zustand die Eingangsseite des Wechselgetriebes von der Elektromaschine abkoppelt. Damit sind zusätzliche Freiheitsgrade geschaffen, die es ermöglichen, sämtliche Betriebssituationen des Hybridantriebs, nämlich sowohl Starten der Brennkraftmaschine, reinen Elektroantrieb, Rekuperieren, Boostbetrieb, reinen verbrennungsmotorischen Antrieb etc. bei günstigen Getriebewirkungsgraden abzubilden. Insbesondere können mit der vorliegenden Erfindungsidee Getriebeverluste im Rekuperationsbetrieb vermieden werden.According to the invention it is proposed that in the power flow to the input shaft of the transmission and behind the first clutch and the transmission drive, a third clutch is turned on, which decouples the input side of the transmission from the electric machine in the open state. Thus, additional degrees of freedom are created, which make it possible to map all operating situations of the hybrid drive, namely both starting the engine, pure electric drive, recuperation, boost mode, pure internal combustion engine drive etc. at favorable transmission efficiencies. In particular, transmission losses in recuperation operation can be avoided with the present invention idea.
Besonders bevorzugt kann der Übersetzungstrieb ein Zahnradtrieb mit einem Zahnrad auf der Antriebswelle der Elektromaschine und einem Zahnrad auf der Eingangswelle des Wechselgetriebes sein, der fertigungstechnisch einfach herstellbar ist und sowohl ein günstiges Übersetzungsverhältnis als auch geringe Antriebsverluste ermöglicht.Particularly preferably, the transmission drive can be a gear drive with a gear on the drive shaft of the electric machine and a gear on the input shaft of the transmission, the production technology is easy to manufacture and allows both a favorable gear ratio and low drive losses.
Alternativ kann der Übersetzungstrieb ein Zahnradtrieb mit einem Zahnrad auf der Antriebswelle der Elektromaschine und einem Zahnrad auf einer Zwischenwelle sein, die über einen weiteren Zahnradtrieb auf die Eingangswelle des Wechselgetriebes abtreibt. Damit gelingt es insbesondere, die Positionierung des Wechselgetriebes an gegebene Einbauverhältnisse im Kraftfahrzeug mit baulich geringem Aufwand anzupassen. Dabei kann die dritte Kupplung entweder vor dem weiteren Zahnradtrieb oder bevorzugt innerhalb des Wechselgetriebes und im Kraftfluss hinter dem weiteren Zahnradtrieb angeordnet sein.Alternatively, the transmission drive may be a gear drive with a gear on the drive shaft of the electric machine and a gear on an intermediate shaft, which abrades via a further gear drive on the input shaft of the gearbox. This makes it possible in particular to adapt the positioning of the gearbox to given installation conditions in the motor vehicle with structurally little effort. In this case, the third clutch can be arranged either before the further gear drive or preferably within the change gear and in the power flow behind the further gear drive.
In besonders vorteilhafter Weiterbildung der Erfindung können die Antriebswelle der Elektromaschine und die Abtriebswelle des Wechselgetriebes auf einen gemeinsamen Abtrieb wirken, der bevorzugt ein an das Wechselgetriebe angebautes Differenzial einer angetriebenen Achse des Kraftfahrzeuges ist, mit dessen Antriebsrad die Elektromaschine über ein erstes Zahnrad und die Abtriebswelle des Wechselgetriebes über ein zweites Zahnrad trieblich verbunden sind. Daraus resultiert eine baulich besonders kompakte und antriebstechnisch robuste Konstruktion, bei der das Antriebsmoment im elektrischen Antrieb direkt von der Elektromaschine zum gemeinsamen Abtrieb (zum Beispiel einem final drive) bzw. zum Differenzial geleitet ist.In a particularly advantageous embodiment of the invention, the drive shaft of the electric machine and the output shaft of the transmission can act on a common output, which is preferably attached to the change gear differential of a driven axle of the motor vehicle, with the drive wheel, the electric machine via a first gear and the output shaft of the Change gear via a second gear are drivingly connected. This results in a structurally particularly compact and robust drive construction, in which the drive torque is passed in the electric drive directly from the electric machine to the common output (for example, a final drive) or to the differential.
Bei einem mit Bezug zur Ausrichtung der Antriebswellen der Brennkraftmaschine und der Elektromaschine quer abtreibenden Differenzial kann das Antriebsrad des Differenziales unmittelbar ein Tellerrad und die damit kämmenden Zahnräder Kegelritzel sein. Damit wird die Konstruktion eines herkömmlichen Differenziales mit baulich geringem Mehraufwand auf den zusätzlichen, direkten Antrieb der Elektromaschine erweitert. In a transverse with respect to the orientation of the drive shafts of the internal combustion engine and the electric machine abzreibenden differential, the drive wheel of the differential directly be a ring gear and the meshing gears bevel pinion. Thus, the construction of a conventional differential with structurally low overhead on the additional, direct drive of the electric machine is extended.
In weiterer vorteilhafter Ausgestaltung der Erfindung kann ausgangsseitig der Abtriebswelle des Wechselgetriebes im Kraftfluss vor dem abtreibenden Zahnrad bzw. Kegelritzel eine vierte Kupplung eingeschaltet sein, die bei elektromotorischem Antrieb geöffnet ist. Durch die Anordnung der vierten Kupplung kann bei rein elektromotorischem Antrieb das Wechselgetriebe komplett abgekoppelt werden, wodurch der elektromotorische Wirkungsgrad weiter verbessert ist.In a further advantageous embodiment of the invention can be switched on the output side of the output shaft of the transmission in the power flow before the abortive gear or bevel pinion, a fourth clutch, which is open at electric motor drive. The arrangement of the fourth clutch, the change gear can be completely decoupled in purely electric motor drive, whereby the electromotive efficiency is further improved.
Die vierte Kupplung kann eine schaltbare Kupplung oder zur Verminderung des steuerungstechnischen und baulichen Aufwandes eine Freilaufkupplung sein, die bei einem Rücktrieb auf die Abtriebswelle geöffnet ist.The fourth clutch may be a shiftable clutch or to reduce the control engineering and construction costs an overrunning clutch, which is open at a return to the output shaft.
Des Weiteren können zur Verbesserung der Gewichtsverteilung und/oder der Anordnung des Antriebsaggregates im Kraftfahrzeug die Brennkraftmaschine und die Elektromaschine achsparallel und einander benachbart angeordnet sein, während die Eingangswelle und die Abtriebswelle des Wechselgetriebes in einem Winkel zu den Antriebswellen der Brennkraftmaschine und der Elektromaschine geneigt sind, wobei der weitere Zahnradtrieb ein Kegeltrieb ist.Furthermore, in order to improve the weight distribution and / or the arrangement of the drive assembly in the motor vehicle, the internal combustion engine and the electric machine may be arranged parallel to and adjacent to each other, while the input shaft and the output shaft of the transmission are inclined at an angle to the drive shafts of the internal combustion engine and the electric machine, wherein the further gear drive is a bevel gear.
Schließlich können die Brennkraftmaschine, die Elektromaschine, das Wechselgetriebe und das Differenzial zu einem gemeinsamen Antriebsaggregat, zum Beispiel für einen Frontantrieb eines Kraftfahrzeuges, zusammengebaut sein.Finally, the internal combustion engine, the electric machine, the change gear and the differential to a common drive unit, for example, for a front-wheel drive of a motor vehicle, be assembled.

The clutches K1, K2, K3 are shiftable clutches (for example, friction clutches, multi-plate clutches or positive clutches) which are arbitrarily or preferably automatically hydraulically or electrically controlled while the clutch K4 is a one-way clutch transmitting torque only in the forward drive direction of the motor vehicle and releases the drive connection in the return drive.
