Abstract
Die Erfindung betrifft ein Hybridantriebssystem für ein Kraftfahrzeug, insbesondere für ein Mild-Hybrid-Fahrzeug, mit mindestens einer Verbrennungskraftmaschine (VKM), mindestens einer Elektromaschine (EM) und mit mindestens einer Trennkupplung (K0), wobei durch die Trennkupplung (K0) eine Verbrennungskraftmaschinenausgangswelle (AW) der Verbrennungskraftmaschine (VKM) mit einer Elektromaschineneingangswelle (EW) der Elektromaschine (EM) drehwirksam verbindbar und davon trennbar ist, wobei die Trennkupplung (K0) dabei im Normalzustand geschlossen ist.Die Gesamteffizienz des Hybridantriebssystems ist dadurch auf einfache und kostengünstige Weise verbessert, dass ein Starter (RSG) zum Starten der Verbrennungskraftmaschine (VKM) vorgesehen ist, wobei beim Starten der Verbrennungskraftmaschine (VKM) durch den Starter (RSG) die Trennkupplung (K0) geöffnet ist.The invention relates to a hybrid drive system for a motor vehicle, in particular for a mild hybrid vehicle, having at least one internal combustion engine (VKM), at least one electric machine (EM) and at least one separating clutch (K0), wherein through the separating clutch (K0) an internal combustion engine output shaft (AW) of the internal combustion engine (VKM) with an electric machine input shaft (EW) of the electric machine (EM) rotatably connectable and separable, the separating clutch (K0) is closed in the normal state. The overall efficiency of the hybrid drive system is thereby improved in a simple and cost-effective manner in that a starter (RSG) is provided for starting the internal combustion engine (VKM), wherein when the internal combustion engine (VKM) is started by the starter (RSG), the separating clutch (K0) is opened.
Description
Die Erfindung betrifft ein Hybridantriebssystem für ein Kraftfahrzeug, insbesondere für ein Mild-Hybrid-Fahrzeug, gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a hybrid drive system for a motor vehicle, in particular for a mild hybrid vehicle, according to the features of the preamble of
Hybridantriebssysteme für Kraftfahrzeuge, insbesondere für Hybrid-Fahrzeuge weisen eine Verbrennungskraftmaschine und eine Elektromaschine auf. Dabei kann eine Verbrennungskraftmaschinenausgangswelle der Verbrennungskraftmaschine durch eine Trennkupplung mit einer Elektromaschineneingangswelle der Elektromaschine drehwirksam verbindbar und davon trennbar sein. Üblicherweise sind diese Trennkupplungen als Lamellenkupplungen ausgeführt, welche im Normalzustand offen bzw. geöffnet sind, was auch als „normally-open“ bezeichnet wird. Derartige Trennkupplungen können mittels einer Hochdruckhydraulik geschlossen werden und werden durch eine Ölkühlung gekühlt.Hybrid drive systems for motor vehicles, in particular for hybrid vehicles, have an internal combustion engine and an electric machine. In this case, an internal combustion engine output shaft of the internal combustion engine by a disconnect clutch with an electric machine input shaft of the electric machine can be rotationally connectable and separable therefrom. Usually, these disconnect couplings are designed as multi-plate clutches, which are open or open in the normal state, which is also referred to as "normally-open". Such disconnect couplings can be closed by means of a high-pressure hydraulics and are cooled by oil cooling.
Aus der
Die im Stand der Technik bekannten Hybridantriebssysteme sind jedoch noch nicht optimal ausgebildet. So weisen die aus dem Stand der Technik bekannten Hybridantriebssysteme noch keine optimale Gesamteffizienz auf. Insbesondere ist dabei eine weitere Einsparung des CO2-Ausstoßes erstrebenswert. Zudem ist bei aus dem Stand der Technik bekannten Hybridantriebssystemen häufig deren Aufbau, Anbindung und Ansteuerung komplex und/oder kostenintensiv. Bei dem aus dem Stand der Technik bekannten Hybridantriebssystemen mit im Normalzustand offenen Lamellenkupplungen können zudem Leckageverluste in der Hydraulik auftreten, da zum Betätigen der Kupplung permanent ein Hydraulikdruck angelegt bzw. realisiert und aufrechterhalten werden muss. Derartige Lamellenkupplungen mit einer Ölkühlung benötigen zudem im Allgemeinen einen großen radialen Bauraum, um das Motordrehmoment übertragen zu können. Zudem können bei derartigen als Lamellenkupplungen ausgeführten Trennkupplungen relativ hohe Schleppleistungsverluste bei geöffneter Kupplung auftreten.However, the hybrid drive systems known in the prior art are not yet optimally designed. Thus, the hybrid drive systems known from the prior art do not yet have optimum overall efficiency. In particular, a further saving in CO 2 emissions is desirable. In addition, in hybrid drive systems known from the prior art, their design, connection and control are often complex and / or cost-intensive. In the known from the prior art hybrid drive systems with open in the normal state multi-plate clutches leakage losses in the hydraulic can also occur because a permanent hydraulic pressure must be applied or realized and maintained for actuating the clutch. Such multi-plate clutches with oil cooling also generally require a large radial space in order to transmit the engine torque can. In addition, in such running as multi-plate clutches disconnect couplings relatively high drag losses occur with the clutch open.
Der Erfindung liegt daher die Aufgabe zu Grunde, das eingangs genannte Hybridantriebssystem, nun derart auszugestalten und weiterzubilden, dass ein Hybridantriebssystem mit einer verbesserten Gesamteffizienz, insbesondere mit einem verringerten CO2-Ausstoß, auf einfache und kostengünstige Weise zur Verfügung gestellt werden kann.The invention is therefore based on the object, the above-mentioned hybrid drive system, now in such a way and further develop that a hybrid drive system with improved overall efficiency, in particular with a reduced CO 2 emissions, can be provided in a simple and cost-effective manner.
Die der Erfindung zugrunde liegende Aufgabe wird nun zunächst durch ein Hybridantriebssystem für ein Kraftfahrzeug, insbesondere für ein Mild-Hybrid-Fahrzeug, mit den Merkmalen des Patentanspruchs 1 gelöst.The object underlying the invention will now be solved first by a hybrid drive system for a motor vehicle, in particular for a mild hybrid vehicle, with the features of
Dabei weist das Hybridantriebssystem eine Verbrennungskraftmaschine, eine Elektromaschine und eine Trennkupplung auf. Durch die Trennkupplung ist dabei eine Verbrennungskraftmaschinenausgangswelle der Verbrennungskraftmaschine mit einer Elektromaschineneingangswelle der Elektromaschine drehwirksam verbindbar und davon trennbar. Die Trennkupplung ist dabei im Normalzustand geschlossen ausgeführt. Insbesondere kann die Trennkupplung als selbsthaltende beziehungsweise haltekraftfreie Kupplung ausgeführt sein. Beispielsweise kann die Trennkupplung zudem als Trockenkupplung ausgeführt sein. Zum Starten der Verbrennungskraftmaschine ist dabei ein Starter vorgesehen. Beim Starten der Verbrennungskraftmaschine durch den Starter ist dabei die Trennkupplung offen bzw. geöffnet. Insbesondere kann die Trennkupplung hydraulisch öffenbar sein.In this case, the hybrid drive system has an internal combustion engine, an electric machine and a separating clutch. Through the separating clutch is an internal combustion engine output shaft of the internal combustion engine with an electric machine input shaft of the electric machine rotationally effective connectable and separable. The separating clutch is executed closed in the normal state. In particular, the separating clutch can be designed as a self-holding or holding force-free coupling. For example, the separating clutch can also be designed as a dry clutch. To start the internal combustion engine while a starter is provided. When starting the internal combustion engine by the starter while the separating clutch is open or opened. In particular, the separating clutch can be hydraulically openable.
Unter einer im Normalzustand geschlossenen Kupplung, welche auch als „normally-closed“-Kupplung bezeichnet wird, kann insbesondere eine Kupplung verstanden werden, welche in einem Normalzustand ohne Ansteuerung beziehungsweise Betätigung, beispielsweise durch eine Hydraulik, geschlossen ist und insbesondere erst durch eine Ansteuerung beziehungsweise Betätigung, beispielsweise durch eine Hydraulik, geöffnet wird.Under a normally closed clutch, which is also referred to as a "normally-closed" clutch, in particular a clutch can be understood, which is closed in a normal state without control or actuation, for example by a hydraulic, and in particular only by a control or Actuation, for example by a hydraulic system, is opened.
Durch den Starter kann die Verbrennungskraftmaschine auf einfache und kostengünstige Weise schnell gestartet werden, wobei durch die beim Starten der Verbrennungskraftmaschine offene Trennkupplung Schleppleistungsverluste durch ein Mitschleppen der Elektromaschine auf einfache und kostengünstige Weise - und insbesondere mit einem geringen konstruktiven Änderungsaufwand - reduziert beziehungsweise vermieden werden können. Dadurch, dass die Trennkupplung im Normalzustand geschlossen und somit selbsthaltend beziehungsweise haltekraftfrei ist und lediglich beim Starten der Verbrennungskraftmaschine durch den Starter geöffnet wird, ist eine Ansteuerung und Betätigung der Trennkupplung, beispielsweise durch eine Hydraulik, und damit eine Energiezufuhr nur noch kurzfristig zum Öffnen der Trennkupplung notwendig. Zudem können so hydraulische Leckageverluste minimiert werden, da kein permanenter Hydraulikdruck zum Schließen der Kupplung benötigt wird und Leckageverluste lediglich kurzzeitig beim Öffnen auftreten können. So können der Energieverbrauch sowie elektrische Ladezyklen und beispielsweise hydraulische Druckspeicherzyklen reduziert werden und auf diese Weise die Gesamteffizienz des Hybridantriebssystems verbessert und insbesondere auch Kohlendioxid (CO2) eingespart werden.By the starter, the internal combustion engine can be started quickly in a simple and cost-effective manner, by the open when starting the internal combustion engine drag losses by entrainment of the electric machine in a simple and cost-effective manner - and in particular with a small design effort - can be reduced or avoided. Characterized in that the clutch in the normal state is closed and thus self-holding or holding power and is only opened when starting the internal combustion engine by the starter, a control and actuation of the clutch, for example by a hydraulic system, and thus a power supply only for a short time to open the clutch necessary. In addition, so hydraulic leakage losses can be minimized, since no permanent hydraulic pressure to close the clutch is required and leakage losses can occur only briefly when opening. Thus, the energy consumption as well as electrical charging cycles and, for example, hydraulic accumulator cycles can be reduced and thus the overall efficiency of the Hybrid drive system improved and in particular carbon dioxide (CO 2 ) can be saved.
Im Rahmen einer bevorzugten Ausgestaltung ist das Hybridantriebssystem als ein Mild-Hybridantriebssystem für ein Mild-Hybrid-Fahrzeug ausgeführt, wobei insbesondere die Elektromaschine eine Elektromaschinenleistung von ≤ 15 kW, beispielsweise von ≤ 12 kW, zum Beispiel von etwa 10 kW, aufweist. Unter einem Mild-Hybridantriebssystem beziehungsweise Mild-Hybrid-Fahrzeug kann insbesondere ein Antriebssystem beziehungsweise Fahrzeug verstanden werden, welches hauptsächlich verbrennungsmaschinell und/oder hybridisch, also kombiniert verbrennungsmaschinell und elektromaschinell, betrieben wird und/oder dessen Elektromaschine eine Elektromaschinenleistung von ≤ 15 kW, insbesondere von ≤ 12 kW, beispielsweise von etwa 10 kW und/oder 48 V, aufweist. Bei einem Mild-Hybridantriebssystem beziehungsweise Mild-Hybrid-Fahrzeug ist daher insbesondere ein verbrennungsmaschineller und/oder hybridischer Betrieb der Hauptbetriebszustand. Bei einem Mild-Hybridantriebssystem beziehungsweise Mild-Hybrid-Fahrzeug kann insbesondere ein rein elektromaschineller Betrieb eine Ausnahme darstellen und/oder die durch einen rein elektrischen Betrieb erzielbare Reichweite sehr gering sein. Durch die Verwendung einer kleinen Elektromaschine, beispielsweise auf der Basis von etwa 10 kW und/oder 48 V, kann Gewicht eingespart und auf diese Weise die Gesamteffizienz des Hybridantriebssystems verbessert und beispielsweise CO2 eingespart werden. Zudem kann so eine kostenintensive Leistungselektronik für ein Hochvoltsystem entfallen und eine kostengünstigere Niedervolt-Leistungselektronik, zum Beispiel für 48 V, eingesetzt werden, was zu einer deutlich besseren Wirtschaftlichkeit beiträgt.In a preferred embodiment, the hybrid drive system is designed as a mild hybrid drive system for a mild hybrid vehicle, in particular, the electric machine has an electric machine power of ≤ 15 kW, for example, ≤ 12 kW, for example, of about 10 kW. A mild-hybrid drive system or mild-hybrid vehicle can be understood in particular as a drive system or vehicle, which is operated by combustion and / or hybrid, ie combined combustion and electromechanical, and / or its electric machine has an electric machine power of ≦ 15 kW, in particular of ≤ 12 kW, for example of about 10 kW and / or 48 V. In a mild-hybrid drive system or mild hybrid vehicle, therefore, in particular an internal combustion and / or hybrid operation is the main operating state. In a mild hybrid drive system or mild hybrid vehicle, in particular, a purely electromechanical operation may represent an exception and / or the range achievable by purely electrical operation may be very low. By using a small electric machine, for example on the basis of about 10 kW and / or 48 V, weight can be saved and in this way the overall efficiency of the hybrid drive system improved and, for example, CO 2 can be saved. In addition, such a costly power electronics for a high-voltage system can be omitted and a cheaper low-voltage power electronics, for example, for 48 V, are used, which contributes to a much better economy.
Im Rahmen einer weiteren Ausgestaltung ist der Starter zum Starten der Verbrennungskraftmaschine ein Riemen-Starter-Generator. So kann die Verbrennungskraftmaschine auf besonders schnelle und einfache sowie energie-, kosten- und gewichtseffiziente Weise gestartet werden und die Gesamteffizienz des Hybridantriebssystems weiter verbessert und insbesondere auch weiteres Kohlendioxid (CO2) eingespart werden.Within the scope of a further embodiment, the starter for starting the internal combustion engine is a belt starter generator. Thus, the internal combustion engine can be started in a particularly fast and simple and energy, cost and weight-efficient manner and further improves the overall efficiency of the hybrid drive system and in particular also further carbon dioxide (CO 2 ) can be saved.
Im Rahmen einer weiteren Ausgestaltung ist durch eine Starter-Kupplung eine Starterausgangswelle des Starters mit einer Verbrennungskraftmaschineneingangswelle der Verbrennungskraftmaschine drehwirksam verbindbar und davon trennbar. Hierbei können die Verbrennungskraftmaschinenausgangswelle und die Verbrennungskraftmaschineneingangswelle als ein Bauteil ausgebildete sein, insbesondere als „Kurbelwelle“ ausgebildet sein. Die Starter-Kupplung kann beispielsweise im Normalzustand offen sein und beispielsweise beim Starten der Verbrennungskraftmaschine durch den Starter insbesondere geschlossen sein beziehungsweise werden. So können Schleppleistungsverluste weiter reduziert und die Gesamteffizienz des Hybridantriebssystems weiter verbessert und insbesondere auch weiteres Kohlendioxid (CO2) eingespart werden.As part of a further embodiment, a starter output shaft of the starter with a combustion engine input shaft of the internal combustion engine can be rotationally effective connected and separable by a starter clutch. Here, the internal combustion engine output shaft and the internal combustion engine input shaft may be formed as a component, in particular be designed as a "crankshaft". The starter clutch may be open, for example, in the normal state and, for example, be closed or be closed by the starter, for example, when starting the internal combustion engine. Thus, drag losses can be further reduced and the overall efficiency of the hybrid drive system further improved and in particular also further carbon dioxide (CO 2 ) can be saved.
Im Rahmen einer weiteren Ausgestaltung ist durch mindestens eine Getriebe-Kupplung eine Elektromaschinenausgangswelle der Elektromaschinenwelle mit einer Getriebeeingangswelle eines Getriebes drehwirksam verbindbar und davon trennbar. Als Radsatz des Getriebes kann dabei ein herkömmlicher Radsatz, beispielsweise eines Getriebes für ein rein verbrennungsmaschinell betreibbares Fahrzeug oder sonstiges Hybridfahrzeug, verwendet werden. So können der konstruktive Aufwand und Kosten weiter verringert werden. Das Getriebe kann insbesondere als ein Doppelkupplungsgetriebe ausgebildet sein. Dabei kann insbesondere durch eine erste Getriebe-Kupplung die Elektromaschinenausgangswelle mit einer ersten Getriebeeingangswelle des Getriebes und durch eine zweite Getriebe-Kupplung die Elektromaschinenausgangswelle mit einer zweiten Getriebeeingangswelle des Getriebes drehwirksam verbindbar und davon trennbar sein. Die mindestens eine Getriebe-Kupplung, insbesondere die erste Getriebe-Kupplung und die zweite Getriebe-Kupplung, kann dabei insbesondere in Form einer Lamellenkupplung ausgestaltet sein. Eine Getriebeausgangswelle des Getriebes kann insbesondere drehwirksam mit einem Differential verbunden sein, insbesondere über welches der Abtrieb, beispielsweise an die Räder des Fahrzeugs, erfolgt.In a further embodiment, an electric machine output shaft of the electric machine shaft with a transmission input shaft of a transmission rotationally effective connectable and separable from at least one gear coupling. As a wheelset of the transmission can be a conventional wheelset, such as a transmission for a pure combustion engine operable vehicle or other hybrid vehicle can be used. Thus, the design effort and costs can be further reduced. The transmission can be designed in particular as a dual-clutch transmission. In this case, in particular by a first transmission clutch, the electric machine output shaft with a first transmission input shaft of the transmission and a second transmission clutch, the electric machine output shaft with a second transmission input shaft of the transmission rotationally effective connectable and be separable. The at least one transmission clutch, in particular the first transmission clutch and the second transmission clutch, can be designed in particular in the form of a multi-plate clutch. A transmission output shaft of the transmission can in particular be rotationally connected to a differential, in particular via which the output, for example to the wheels of the vehicle, takes place.
Im Rahmen einer weiteren Ausgestaltung sind die Elektromaschineneingangswelle und die Elektromaschinenausgangswelle als eine Rotorwelle der Elektromaschine ausgeführt, zum Beispiel welche den Rotor der Elektromaschine trägt.In a further embodiment, the electric machine input shaft and the electric machine output shaft are designed as a rotor shaft of the electric machine, for example, which carries the rotor of the electric machine.
Im Rahmen einer weiteren Ausgestaltung weist die Trennkupplung ein mit der Rotorwelle der Elektromaschine drehfest verbundenes Elektromaschinen-Kupplungsteil und ein mit der Getriebeeingangswelle drehfest verbundenes Verbrennungskraftmaschinenausgangswellen-Kupplungsteil sowie ein Federpaket und einen hydraulisch, insbesondere axial, bewegbaren Kolben auf. Dabei drückt insbesondere das Federpaket den Kolben gegen den Verbrennungskraftmaschinenausgangswellen-Kupplungsteil und den Verbrennungskraftmaschinenausgangswellen-Kupplungsteil gegen den Elektromaschinen-Kupplungsteil, so dass die Kupplung im Normalzustand geschlossen ist beziehungsweise schließt. Der Kolben kann dabei insbesondere hydraulisch gegen den durch das Federpaket ausgeübten Druck bewegbar sein beziehungsweise werden und so die Kupplung hydraulisch öffenbar sein beziehungsweise geöffnet werden.In the context of a further embodiment, the separating clutch has a with the rotor shaft of the electric machine rotatably connected electric machine coupling part and a rotatably connected to the transmission input shaft internal combustion engine output shaft coupling part and a spring assembly and a hydraulic, in particular axially, movable piston. In particular, the spring assembly presses the piston against the internal combustion engine output shaft coupling part and the internal combustion engine output shaft coupling part against the electric machine coupling part, so that the clutch is closed or closes in the normal state. The piston can in particular be hydraulically movable against the pressure exerted by the spring assembly or be and thus the clutch be hydraulically openable or be opened.
Im Rahmen einer weiteren bevorzugten weiteren Ausgestaltung ist die Trennkupplung in Form einer, insbesondere selbstsynchronisierenden, Zahnkupplung, beispielsweise Klauenkupplung, ausgebildet. Dabei kann die Trennkupplung insbesondere einen axial unverschiebbaren, insbesondere radial drehbaren, mit der Rotorwelle der Elektromaschine drehfest verbundenen Elektromaschinen-Kupplungsteil, beispielsweise mit einer Innenverzahnung, und einen axial verschiebbaren, insbesondere radial drehbaren, mit der Verbrennungskraftmaschinenausgangswelle drehfest verbundenen Verbrennungskraftmaschinenausgangswellen-Kupplungsteil, beispielsweise mit einer Außenverzahnung, sowie ein Federpaket und einen hydraulisch bewegbaren Kolben aufweisen. Dabei kann das Federpaket insbesondere den Kolben gegen den axial verschiebbaren Verbrennungskraftmaschinenausgangswellen-Kupplungsteil und den axial verschiebbaren Verbrennungskraftmaschinenausgangswellen-Kupplungsteil gegen den axial unverschiebbaren Elektromaschinen-Kupplungsteil drücken und so die Kupplung im Normalzustand geschlossen sein beziehungsweise schließen. Der Kolben kann dabei insbesondere hydraulisch gegen den durch das Federpaket ausgeübten Druck bewegbar sein und so die Zahnkupplung, beispielsweise Klauenkupplung, hydraulisch öffenbar sein beziehungsweise geöffnet werden. In the context of a further preferred further embodiment, the separating clutch is in the form of a, in particular self-synchronizing, toothed coupling, for example a dog clutch. In this case, the separating clutch in particular an axially immovable, in particular radially rotatable, rotatably connected to the rotor shaft of the electric machine electric machine coupling part, and an axially displaceable, in particular radially rotatable, with the internal combustion engine output shaft rotatably connected internal combustion engine output shaft coupling part, for example with a External teeth, and have a spring assembly and a hydraulically movable piston. In this case, the spring assembly can in particular press the piston against the axially displaceable internal combustion engine output shaft coupling part and the axially displaceable internal combustion engine output shaft coupling part against the axially non-displaceable electric machine coupling part and thus close or close the clutch in the normal state. The piston can in particular be hydraulically movable against the pressure exerted by the spring assembly pressure and so the gear coupling, for example, dog clutch, be hydraulically openable or be opened.
Im Rahmen einer speziellen Ausgestaltung hiervon weist die Zahnkupplung, beispielsweise Klauenkupplung, weiterhin eine Synchronisationseinrichtung auf. Dabei kann insbesondere der axial unverschiebbare Elektromaschinen-Kupplungsteil weiterhin einen Synchronring und der axial verschiebbare Verbrennungskraftmaschinenausgangswellen-Kupplungsteil weiterhin eine, insbesondere durch ein weiteres Federpaket, federbelastete, in den Synchronring eingreifbare Synchronisationsverzahnung aufweisen. So kann eine Synchronisation der Kupplungsteile beim Schließen der Zahnkupplung, beispielsweise der Klauenkupplung, sichergestellt werden.In the context of a specific embodiment thereof, the toothed coupling, for example a dog clutch, furthermore has a synchronization device. In this case, in particular, the axially non-slidable electrical machine coupling part further comprises a synchronizer ring and the axially displaceable internal combustion engine output shaft coupling part further, in particular by a further spring assembly, spring-loaded, engageable in the synchronizer ring synchronization teeth. Thus, a synchronization of the coupling parts when closing the gear coupling, for example, the dog clutch, can be ensured.
Im Rahmen einer weiteren bevorzugten Ausgestaltung ist die Trennkupplung in Form einer Lamellenkupplung ausgebildet. Dabei kann die Trennkupplung insbesondere ein Lamellenpaket, ein Federpaket und einen hydraulisch bewegbaren Kolben aufweisen. Das Lamellenpaket kann dabei insbesondere mehrere axial verschiebbare, mit der Rotorwelle der Elektromaschine über einen Außenlamellenträger drehfest angeordnete Außenlamellen, und mehrere axial verschiebbare, mit der Verbrennungskraftmaschinenausgangswelle über einen Innenlamellenträger drehfest angeordnete Innenlamellen aufweisen. Dabei kann das Federpaket insbesondere den Kolben gegen das Lamellenpaket - und insbesondere die Innenlamellen und Außenlamellen des Lamellenpaketes gegeneinander - drücken und so die Lamellenkupplung im Normalzustand geschlossen sein beziehungsweise schließen. Der Kolben kann dabei hydraulisch gegen den durch das Federpaket ausgeübten Druck bewegbar sein und so die Lamellenkupplung hydraulisch öffenbar sein beziehungsweise geöffnet werden.In the context of another preferred embodiment, the separating clutch is designed in the form of a multi-disc clutch. In this case, the separating clutch may in particular have a disk pack, a spring assembly and a hydraulically movable piston. The disk set may in particular have a plurality of axially displaceable, with the rotor shaft of the electric machine via an outer disk carrier rotatably mounted outer disk, and a plurality of axially displaceable, with the internal combustion engine output shaft via an inner disk carrier rotatably disposed inner disks. In this case, the spring package, in particular the piston against the disk set - and in particular the inner disks and outer disks of the disk set against each other - press and so closed or close the multi-plate clutch in the normal state. The piston can be hydraulically movable against the pressure exerted by the spring assembly pressure and so the multi-plate clutch be hydraulically openable or be opened.
Zur hydraulischen Bewegung des Kolbens gegen den durch das Federpaket ausgeübten Druck kann bei den oben beschriebenen Ausführungsformen dabei ein Hydraulikmittel durch einen in der Verbrennungskraftmaschinenausgangswelle ausgebildeten Kanal zuführbar sein beziehungsweise werden.For the hydraulic movement of the piston against the pressure exerted by the spring assembly, in the case of the embodiments described above, a hydraulic fluid can be supplied by a channel formed in the internal combustion engine output shaft.
Die eingangs genannten Nachteile sind daher vermieden und entsprechende Vorteile sind erzielt.The aforementioned disadvantages are therefore avoided and corresponding advantages are achieved.
