Description
Die Erfindung betrifft eine Schwungstartkupplungsanordnung mit einer Reibungskupplung und einer Freilaufanordnung.The invention relates to a fly-starting clutch assembly with a friction clutch and a freewheel assembly.
Ein Problem bei hybridisierten Antriebssträngen besteht darin, dass der Elektromotor eine Leistungsreserve vorhalten muss, um bei rein elektromotorischer Fahrt den Verbrennungsmotor hochzuziehen.A problem with hybrid powertrains is that the electric motor has to maintain a power reserve in order to pull up the engine in a purely electromotive drive.
Daher ist es bekannt, eine Schwungstartkupplung vor der ersten Schwungmasse anzuordnen. Dadurch kann die Schwungmasseneinrichtung bei elektromotorischer Fahrt als Energiespeicher verwendet werden.Therefore, it is known to arrange a fly start clutch before the first flywheel. As a result, the flywheel device can be used in an electromotive drive as energy storage.
Schwungstartkupplungsanordnungen sind Kupplungsanordnungen zur Anordnung zwischen einer Verbrennungskraftmaschine und der ersten oder der Schwungmasse. Diese dienen dazu, den Verbrennungsmotor nach einer Siegelphase oder der Stopphase an einer Ampel mittels eines Elektromotors wieder hochzuziehen.Flywheel clutch assemblies are clutch assemblies for placement between an internal combustion engine and the first or flywheel. These serve to pull the engine up again after a sealing phase or the stop phase at a traffic light by means of an electric motor.
Ein Problem besteht dabei in einer effizienten Auslegung der Kupplung. Bekannt sind trockenlaufende Reibungskupplungen, die das gesamte Drehmoment übertragen.One problem is the efficient design of the coupling. Are known dry running friction clutches that transmit the entire torque.
Zur Lösung dieses Problems wird vorgeschlagen, dass die Ausgangsseite der Reibungskupplung und die Ausgangsseite der Freilaufanordnung mit einer Schwungmasseneinrichtung verbindbar sind. Die Schwungstartkupplungsanordnung soll also vor der ersten Schwungmasse angeordnet werden, wodurch der Elektromotor die Schwungmasse während der rein elektromotorischen Fahrt weiter antreibt und diese dann als Energiespeicher verwendet wird. Dabei wird zwar geringfügig mehr Energie verbraucht als bei einer direkten Anordnung der Schwungmasse nach dem Verbrennungsmotor, jedoch kann dadurch der Elektromotor mit weniger Leistung ausgestattet werden. Auch ist die eingesetzte Energie verhältnismäßig gering, da die Schwungmasse nur am Laufen gehalten werden muss, da sie beim Abkoppeln des Verbrennungsmotors sowieso eine gewisse Drehenergie aufweist. Es sind durch den Elektromotor also lediglich Reibungsverluste auszugleichen.To solve this problem, it is proposed that the output side of the friction clutch and the output side of the freewheel assembly can be connected to a flywheel device. The flywheel clutch assembly should therefore be arranged in front of the first flywheel, whereby the electric motor continues to drive the flywheel during the purely electromotive drive and this is then used as energy storage. Although slightly more energy is consumed than in a direct arrangement of the flywheel after the engine, but this can be equipped with less power by the electric motor. Also, the energy used is relatively low, since the flywheel only has to be kept running, as it anyway has a certain rotational energy when uncoupling the engine. There are only offset by the electric motor friction losses.
Vorzugsweise kann die Freilaufanordnung einen Freilaufaußenring, wenigstens ein Klemmelement und einen Freilaufinnenring aufweisen. Der Freilauf lässt sich dabei in einer Drehrichtung frei drehen, während sich die Klemmelemente in der anderen Richtung verklemmen und so Drehmoment übertragen wird.Preferably, the freewheel assembly may comprise a freewheel outer ring, at least one clamping element and a freewheel inner ring. The freewheel can be freely rotate in one direction, while the clamping elements jam in the other direction and torque is transmitted.
Vorteilhafterweise kann das wenigstens eine Klemmelement als Rolle ausgebildet sein. Hierbei handelt es sich um eine besonders effektive Ausgestaltung bei der Nutzung des Freilaufs als Kupplung.Advantageously, the at least one clamping element can be designed as a roller. This is a particularly effective embodiment when using the freewheel as a clutch.
Vorzugsweise kann einer der Ringe des Freilaufs, insbesondere der Freilaufinnenring, auch die Eingangsnabe der Reibungskupplung bilden. Damit sind sowohl der Eingang als auch der Ausgang der Reibungskupplung und der Freilaufanordnung mit den gleichen Bauteilen verbunden. Die Reibungskupplung und die Freilaufanordnung sind also parallel zueinander angeordnet und können das auftretende Drehmoment gemeinsam übertragen. Durch die Ausbildung des Freilaufinnenrings als Reibungskupplungsnabe und umgekehrt ergibt sich ein besonders kompakter Aufbau der Schwungstartkupplungsanordnung.Preferably, one of the rings of the freewheel, in particular the freewheel inner ring, also form the input hub of the friction clutch. Thus, both the input and the output of the friction clutch and the freewheel assembly are connected to the same components. The friction clutch and the freewheel assembly are thus arranged parallel to each other and can transmit the torque occurring together. Due to the design of the freewheel inner ring as a friction clutch hub and vice versa results in a particularly compact design of the flywheel clutch assembly.
Vorteilhafterweise kann die Freilaufanordnung auf der Schwungmasseneinrichtung lagerbar sein. Vorzugsweise kann die Freilaufanordnung radial innerhalb der Kupplungsanordnung und/oder der Schwungmasseneinrichtung angeordnet sein. Aufgrund der beiden zu verwendenden Ringe ist es günstig, wenn die Freilaufanordnung einen geringen Außendurchmesser aufweist, weshalb sie bei Anordnung radial innen kompaktbauend ist.Advantageously, the freewheel assembly can be stored on the flywheel device. Preferably, the freewheel assembly may be disposed radially within the clutch assembly and / or the flywheel device. Due to the two rings to be used, it is advantageous if the freewheel assembly has a small outer diameter, which is why it is radially compact design when arranged radially inside.
Vorteilhafterweise kann die Reibungskupplung als normally-open Kupplung ausgebildet sein. Weiterhin kann die Reibungskupplung als nasslaufende Kupplung ausgebildet sein. Die Reibungskupplung der Schwungstartkupplungsanordnung ist aber keine Anfahrkupplung, da sie lediglich dem hochziehen des Verbrennungsmotors dient. Bei der Auslegung der Bauteile kann diese daher kleiner dimensioniert werden als eine Anfahrkupplung, da Anfahrkupplungen große Wärmemengen aufnehmen können müssen.Advantageously, the friction clutch may be formed as a normally-open clutch. Furthermore, the friction clutch may be formed as a wet-running clutch. The friction clutch of the flywheel clutch assembly is not a starting clutch, since it only serves to pull up the engine. In the design of the components, this can therefore be dimensioned smaller than a starting clutch, since starting clutches must be able to absorb large amounts of heat.
Vorteilhafterweise kann die Reibungskupplung als Lamellenkupplung ausgebildet sein. Auch die Freilaufanordnung kann dann im Nassraum der Lamellenkupplung angeordnet werden, wodurch Öl zur Schmierung des Freilaufs automatisch vorhanden ist.Advantageously, the friction clutch may be formed as a multi-plate clutch. The freewheel arrangement can then be arranged in the wet space of the multi-plate clutch, whereby oil for the lubrication of the freewheel is automatically present.
Vorteilhafterweise kann der Eingangslamellenträger, insbesondere der Außenlamellenträger, mit dem Eingangsteil des Freilaufs drehfest verbunden sein. Hierbei kann es sich wie weiter oben bereits beschrieben um eine Nabe handeln, die gleichzeitig ein Ring des Freilaufs ist.Advantageously, the input disk carrier, in particular the outer disk carrier, be rotatably connected to the input part of the freewheel. As already described above, this may be a hub, which at the same time is a ring of the freewheel.
Vorteilhafterweise kann der Innenlamellenträger den Ausgang der Reibungskupplung bilden. Dieser ist dann mit der Schwungmasseneinrichtung verbunden. Vorteilhafterweise kann der Ausgang der Reibungskupplung mit der Schwungmasseneinrichtung verschraubbar sein.Advantageously, the inner disk carrier can form the output of the friction clutch. This is then connected to the flywheel device. Advantageously, the output of the Friction clutch to be screwed to the flywheel device.
Daneben betrifft die Erfindung eine Antriebsstrangeinheit mit einer Schwungstartkupplungsanordnung und wenigstes einem Teil einer Schwungmasseneinrichtung. Die Antriebsstrangeinheit zeichnet sich dadurch aus, dass die Schwungstartkupplungsanordnung wie beschrieben ausgebildet ist.In addition, the invention relates to a drive train unit with a fly start clutch assembly and at least a part of a flywheel device. The drive train unit is characterized in that the swing start clutch assembly is formed as described.
Vorteilhafterweise kann die Schwungmasseneinrichtung als Zweimassenschwungrad ausgebildet sein. In diesem Fall sind der Ausgang der Reibungskupplung und der Freilaufanordnung mit der Primärseite des Zweimassenschwungrads verbunden oder verbindbar. Insbesondere kann der Freilaufaußenring als Eingangsnabe des Zweimassenschwungrads ausgebildet sein. Auch hierdurch kann eine extrem kompakte Anordnung der Antriebsstrangeinheit erreicht werden.Advantageously, the flywheel device can be designed as a dual-mass flywheel. In this case, the output of the friction clutch and the freewheel assembly are connected or connectable to the primary side of the dual mass flywheel. In particular, the freewheel outer ring may be formed as an input hub of the dual mass flywheel. This also allows an extremely compact arrangement of the drive train unit can be achieved.
Vorteilhafterweise kann die Reibungskupplung eine Betätigungseinrichtung aufweisen, die mittels Drucköl betätigbar ist. Dabei kann ein Teil des Druckraums in der Schwungmasseneinrichtung ausgebildet sein.Advantageously, the friction clutch may comprise an actuating device which can be actuated by means of pressure oil. In this case, a part of the pressure chamber may be formed in the flywheel device.
Vorzugsweise kann der Antriebsstrang auf der Ausgangsseite der Schwungmasseneinrichtung eine Trennkupplung und/oder einen Tilger und/oder einen Torsionsdämpfer aufweisen. Die Kombination eines Zweimassenschwungrades und eines Fliehkraftpendels oder Tilgers ist grundsätzlich bekannt.Preferably, the drive train on the output side of the flywheel mass means may comprise a separating clutch and / or a Tilger and / or a torsion damper. The combination of a dual-mass flywheel and a centrifugal pendulum or absorber is basically known.
Vorteilhaftweise kann der Antriebsstrang auf der Ausgangseite der Schwungmasseneinrichtung einen Elektromotor aufweisen. Das bedeutet, dass der Elektromotor auf der Ausgangseite der Schwungmasseneinrichtung Drehmoment abgibt. Dies ist beispielsweise bei sogenannten P2-Anordnungen der Fall. Es bedeutet nicht, dass der Elektromotor selbst koaxial oder wie auch immer an dieser Stelle zu platzieren wäre.Advantageously, the drive train may have an electric motor on the output side of the flywheel device. This means that the electric motor outputs torque on the output side of the flywheel device. This is the case, for example, in so-called P2 arrangements. It does not mean that the electric motor itself would be coaxial or whatever place it would place at that point.
Vorteilhafterweise kann die Eingangsseite der Schwungstartkupplungsanordnung mit der Kurbelwelle einer Verbrennungskraftmaschine verbunden sein. Insbesondere kann die Verbindung mittels einer axial elastischen Plattenanordnung realisiert sein. Dabei können beispielsweise zwei elastische Platten miteinander, mit der Kurbelwelle und mit der Kupplungseingangsnabe verschraubt sein.Advantageously, the input side of the flywheel clutch assembly may be connected to the crankshaft of an internal combustion engine. In particular, the connection can be realized by means of an axially elastic plate arrangement. In this case, for example, two elastic plates can be bolted together, with the crankshaft and with the Kupplungsseingangsnabe.
