Aus
Es besteht ein ständiges Bedürfnis an einem alternativen insbesondere verschleißarmen Antriebsstrang für ein Hybrid-Kraftfahrzeug.There is a constant need for an alternative, particularly low-wear drive train for a hybrid motor vehicle.
Es ist die Aufgabe der Erfindung Maßnahmen aufzuzeigen, die einen alternativen insbesondere verschleißarmen Antriebsstrang für ein Hybrid-Kraftfahrzeug ermöglichen.It is the object of the invention to show measures that allow an alternative, particularly low-wear drive train for a hybrid motor vehicle.
Die Lösung der Aufgabe erfolgt erfindungsgemäß durch einen Antriebsstrang mit den Merkmalen des Anspruchs 1. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen und der nachfolgenden Beschreibung angegeben, die jeweils einzeln oder in Kombination einen Aspekt der Erfindung darstellen können.The object is achieved according to the invention by a drive train having the features of claim 1. Preferred embodiments of the invention are specified in the subclaims and the following description, each of which individually or in combination may represent an aspect of the invention.
Erfindungsgemäß ist ein Antriebsstrang für ein Hybrid-Kraftfahrzeug vorgesehen mit einer Antriebswelle eines Kraftfahrzeugmotors zum mechanischen Antreiben des Hybrid-Kraftfahrzeugs, einer elektrischen Maschine zum elektrischen Antreiben des Hybrid-Kraftfahrzeugs, wobei die elektrische Maschine einen mit einer Rotorwelle verbundenen Rotor aufweist, einem Zweimassenschwungrad zur Dämpfung von Drehzahlschwankungen der Antriebswelle, wobei das Zweimassenschwungrad eine Primärmasse und eine mit der Primärmasse über ein, insbesondere als Bogenfeder ausgestaltetes, Energiespeicherelement begrenzt verdrehbar gekoppelte Sekundärmasse aufweist, einem Freilauf zur Drehmomentübertragung von der Antriebswelle über das Zweimassenschwungrad an die Rotorwelle und zur Unterbrechung einer Drehmomentübertragung von der Rotorwelle an die Antriebswelle und einem Koppelaggregat zur Drehmomentübertragung von der Rotorwelle an die Antriebswelle, wobei das Koppelaggregat den Freilauf überbrückt, und wobei insbesondere das Koppelaggregat zumindest einen Teil des Zweimassenschwungrads überbrückt.According to the invention, a drive train for a hybrid motor vehicle is provided with a drive shaft of an automobile engine for mechanically driving the hybrid motor vehicle, an electric machine for electrically driving the hybrid motor vehicle, wherein the electric machine has a rotor connected to a rotor shaft, a dual-mass flywheel for damping of rotational speed fluctuations of the drive shaft, wherein the dual mass flywheel has a primary mass and with the primary mass via a, in particular designed as a bow spring, energy storage element limited rotatably coupled secondary mass, a freewheel for transmitting torque from the drive shaft via the dual mass flywheel to the rotor shaft and to interrupt a torque transmission of the Rotor shaft to the drive shaft and a coupling unit for torque transmission from the rotor shaft to the drive shaft, wherein the coupling unit bridges the freewheel, and wherein in particular the coupling unit bridges at least a part of the dual mass flywheel.
Der Freilauf kann sicherstellen, dass im Zugbetrieb, wenn eine Drehmomentübertragung von dem insbesondere als Verbrennungskolbenmotor ausgestalteten Kraftfahrzeugmotor an die Rotorwelle erfolgt, das von dem Kraftfahrzeugmotor erzeugte Drehmoment über das Zweimassenschwungrad fließt. Dadurch können vom Kraftfahrzeugmotor unvermeidbar erzeugte Drehschwingungen, insbesondere mit der Frequenz eines ganzzahligen Vielfaches der Motorordnung des Kraftfahrzeugmotors, gedämpft werden. Gleichzeitig kann der Freilauf bei einem Überholen der elektrischen Maschine die Drehmomentübertragung unterbrechen, damit die von der elektrischen Maschine eingebrachte Antriebsleistung nicht durch ein Mitschleppen der Massenträgheitsmomente des Verbrennungskolbenmotors geschmälert wird.The freewheel can ensure that in the train operation, when a torque transmission from the engine motor designed in particular as a combustion piston engine takes place to the rotor shaft, the torque generated by the motor vehicle engine flows through the dual mass flywheel. As a result, torsional vibrations unavoidably generated by the motor vehicle engine, in particular with the frequency of an integral multiple of the motor system of the motor vehicle engine, can be damped. At the same time, the freewheel can interrupt the transmission of torque when the electric machine is overtaken, so that the drive power introduced by the electric machine is not diminished by entrainment of the mass moments of inertia of the internal combustion piston engine.
Um mit Hilfe der elektrischen Maschine den Verbrennungskolbenmotor starten zu können, kann der Freilauf von dem Koppelaggregat überbrückt werden, so dass zum Starten des Verbrennungskolbenmotors eine Drehmomentübertragung von der elektrischen Maschine an den Verbrennungskolbenmotor erfolgen kann. Je nachdem, ob der Freilauf in Kraftflussrichtung beim Zugbetrieb des Kraftfahrzeugmotors vor oder nach dem Zweimassenschwungrad vorgesehen ist, kann das Koppelaggregat bei einer Anordnung in Kraftflussrichtung beim Zugbetrieb des Kraftfahrzeugmotors vor oder nach dem Zweimassenschwungrad verschiedene vorteilhafte Effekte erzeugen. Insbesondere kann das Koppelaggregat nicht nur den Freilauf sondern auch das Zweimassenschwungrad ganz oder teilweise überbrücken. Hierbei wird die Erkenntnis ausgenutzt, dass bei einem Drehmomenteintrag der elektrischen Maschine keine Drehschwingungen zu erwarten sind. Bei einem gewünschten Schubbetrieb des Kraftfahrzeugmotors, beispielsweise wenn der Kraftfahrzeugmotor als Motorbremse dienen soll oder die elektrische Maschine den Kraftfahrzeugmotor starten soll, kann das insbesondere wahlweise schaltbare Koppelaggregat einen Drehmomentfluss von der elektrischen Maschine an den Kraftfahrzeugmotor herbeiführen und hierbei beispielsweise das Energiespeicherelement des Zweimassenschwungrads überbrücken. Das Energiespeicherelement des Zweimassenschwungrads kann dadurch im Schubbetrieb geschont werden, wodurch unnötige Belastungen vermieden sind. Insbesondere kann das Zweimassenschwungrad für einen bevorzugten oder ausschließlichen Zugbetrieb ausgelegt werden, so dass die Funktionalität und/oder Robustheit des Zweimassenschwungrads gesteigert werden kann. Durch das den Freilauf und insbesondere zumindest einen Teil des Zweimassenschwungrads überbrückende Koppelaggregat ist ein alternativer und insbesondere durch die Schonung des Zweimassenschwungrads im Schubbetrieb verschleißarmer Antriebsstrang für ein Hybrid-Kraftfahrzeug ermöglicht.In order to be able to start the internal combustion piston engine with the aid of the electric machine, the freewheel can be bridged by the coupling unit, so that torque can be transmitted from the electric machine to the internal combustion engine to start the internal combustion piston engine. Depending on whether the freewheel is provided in the power flow direction during traction of the motor vehicle engine before or after the dual mass flywheel, the coupling unit can produce different advantageous effects before or after the dual mass flywheel in an arrangement in the direction of force flow during traction of the motor vehicle engine. In particular, the coupling unit can bridge not only the freewheel but also the dual mass flywheel in whole or in part. Here, the knowledge is exploited that at a torque input of the electric machine no torsional vibrations are to be expected. In a desired overrun operation of the motor vehicle engine, for example, when the motor vehicle engine is to serve as an engine brake or the electric machine to start the motor vehicle, the particular selectively switchable coupling unit can cause a torque flow from the electric machine to the motor vehicle engine and in this case, for example, bridge the energy storage element of the dual mass flywheel. The Energy storage element of the dual mass flywheel can be spared in overrun, thereby unnecessary loads are avoided. In particular, the dual-mass flywheel can be designed for a preferred or exclusive train operation, so that the functionality and / or robustness of the dual-mass flywheel can be increased. By the freewheel and in particular at least a portion of the dual mass flywheel bridging coupling unit is an alternative and particularly by the conservation of the dual mass flywheel in overrun low-wear powertrain for a hybrid motor vehicle allows.
Wenn der Freilauf an der Antriebswelle und der Primärmasse des Zweimassenschwungrads angreift, kann das Koppelaggregat beispielswiese an der Antriebswelle und der Primärmasse oder an der Antriebswelle und der Sekundärmasse des Zweimassenschwungrads oder an der Antriebswelle und der Rotorwelle angreifen. Wenn der Freilauf an der Sekundärmasse und der Rotorwelle angreift, kann das Koppelaggregat beispielsweise an der Rotorwelle und der Sekundärmasse oder an der Rotorwelle und der Primärmasse oder an der Rotorwelle und der Antriebswelle angreifen. Die elektrische Maschine weist insbesondere einen Stator auf, der stromdurchfließbare Spulen aufweist. Der Stator kann mit dem Rotor zusammenwirken, der insbesondere Permanentmagnete aufweist. Die Rotorwelle ist vorzugsweise einstückig, das heißt die Sekundärmasse ist direkt mit der Rotorwelle drehfest verbunden oder ausschließlich über den Freilauf und/oder das Koppelaggregat mit der Rotorwelle verbunden. Insbesondere ist der Rotor, insbesondere die Permanentmagnete des Rotors, drehfest mit der Rotorwelle verbunden. Vorzugsweise ist zwischen dem Zweimassenschwungrad und der elektrischen Maschine keine von dem Freilauf und/oder von dem Koppelaggregat verschiedene Trennkupplung vorgesehen. Die Rotorwelle ist insbesondere über eine Kupplung mit einem Kraftfahrzeuggetriebe koppelbar, das Antriebsräder des Hybrid-Kraftfahrzeugs antreiben kann.When the freewheel on the drive shaft and the primary mass of the dual mass flywheel attacks, the coupling unit example, the attack on the drive shaft and the primary mass or on the drive shaft and the secondary mass of the dual mass flywheel or on the drive shaft and the rotor shaft. When the freewheel on the secondary mass and the rotor shaft attacks, the coupling unit can attack, for example, on the rotor shaft and the secondary mass or on the rotor shaft and the primary mass or on the rotor shaft and the drive shaft. The electric machine has, in particular, a stator which has current-flowable coils. The stator can interact with the rotor, which in particular has permanent magnets. The rotor shaft is preferably in one piece, that is, the secondary mass is rotatably connected directly to the rotor shaft or connected exclusively via the freewheel and / or the coupling unit with the rotor shaft. In particular, the rotor, in particular the permanent magnets of the rotor, rotatably connected to the rotor shaft. Preferably, no separating clutch different from the freewheel and / or from the coupling unit is provided between the dual mass flywheel and the electric machine. The rotor shaft can be coupled in particular via a clutch with a motor vehicle transmission which can drive drive wheels of the hybrid motor vehicle.
Insbesondere ist der Freilauf zwischen der Antriebswelle und der Primärmasse vorgesehen. Der Freilauf ist dadurch im Zugbetrieb des Kraftfahrzeugmotors vor dem Zweimassenschwungrad vorgesehen. Dadurch kann bei einer die Antriebswelle überholenden Rotorwelle das Massenträgheitsmoment des Zweimassenschwungrads genutzt werden, plötzliche Änderungen im Drehmomenteintrag der elektrischen Maschine zu dämpfen und einen besseren Segelbetrieb des Hybrid-Kraftfahrzeugs zu ermöglichen.In particular, the freewheel between the drive shaft and the primary mass is provided. The freewheel is thereby provided in the traction mode of the motor vehicle engine in front of the dual mass flywheel. As a result, in the case of a rotor shaft overhauling the drive shaft, the moment of inertia of the dual-mass flywheel can be used to dampen sudden changes in the torque input of the electric machine and to enable a better sailing operation of the hybrid motor vehicle.
Vorzugsweise ist das Koppelaggregat als schaltbare Kupplung, insbesondere Reibungskupplung, ausgestaltet, wobei die Kupplung zwischen der Sekundärmasse und der Antriebswelle vorgesehen ist. Wenn die Kupplung geschlossen wird, kann die Sekundärmasse von der elektrischen Maschine mitgedreht werden. Dadurch werden auch das Energiespeicherelement und die Primärmasse mitgedreht. Dies ermöglicht es das Zweimassenschwungrad als Schwungscheibe zu nutzen, indem die elektrische Maschine bei geöffneter Kupplung zunächst das Zweimassenschwungrad in Drehung versetzt, während der Freilauf eine Drehmomentübertragung unterbricht, und nachfolgend die Kupplung schließt, so dass zusätzlich zum Drehmomenteintrag der elektrischen Maschine auch das Massenträgheitsmoment des Zweimassenschwungrads einen Beitrag zum Startmoment für den Kraftfahrzeugmotor leistet. Preferably, the coupling unit as a switchable coupling, in particular friction clutch, designed, wherein the coupling between the secondary mass and the drive shaft is provided. When the clutch is closed, the secondary mass can be rotated by the electric machine. As a result, the energy storage element and the primary mass are also rotated. This makes it possible to use the dual mass flywheel as a flywheel by the electric machine with the clutch first set the dual mass flywheel in rotation, while the freewheel breaks a torque transmission, and subsequently closes the clutch, so that in addition to the torque input of the electric machine and the moment of inertia of the dual mass flywheel makes a contribution to the starting torque for the motor vehicle engine.
Besonders bevorzugt ist das Koppelaggregat als, insbesondere schaltbarer, Überbrückungsfreilauf zur Drehmomentübertragung von der Rotorwelle an die Antriebswelle ausgestaltet, wobei insbesondere der Überbrückungsfreilauf zwischen der Sekundärmasse und der Antriebswelle vorgesehen ist. Der Überbrückungsfreilauf kann im geschalteten Zustand eine Drehmomentübertragung von der Sekundärmasse an die Antriebswelle herbeiführen kann. Eine Drehmomentübertragung von der Antriebswelle an die Rotorwelle wird von dem Überbrückungsfreilauf unterbrochen und erfolgt nur über den Freilauf. Der Überbrückungsfreilauf kann im Vergleich zu einer Kupplung robuster und verschleißfester ausgestaltet sein. Insbesondere können bei dem Überbrückungsfreilauf verschleißbehaftete Reibbeläge vermieden sein, so dass auch eine Verschleißnachstellung eingespart werden kann. Insbesondere ist vorgesehen, dass durch den Überbrückungsfreilauf das Zweimassenschwungrad ganz oder teilweise im Schubbetrieb überbrückt ist.Particularly preferably, the coupling unit is designed as, in particular switchable, bridging freewheel for transmitting torque from the rotor shaft to the drive shaft, wherein in particular the bridging freewheel between the secondary mass and the drive shaft is provided. The lock-up freewheel can bring about a torque transmission from the secondary mass to the drive shaft in the switched state. A torque transmission from the drive shaft to the rotor shaft is interrupted by the lock-up freewheel and takes place only via the freewheel. The lock-up freewheel can be made more robust and wear-resistant compared to a clutch. In particular, in the bridging freewheel wear-affected friction linings can be avoided, so that a wear adjustment can be saved. In particular, it is provided that the two-mass flywheel is completely or partially bridged in overrun mode by the lock-up freewheel.
