Description
Die Erfindung betrifft einen Hybridantriebsstrang mit einer Brennkraftmaschine mit einer um eine erste Drehachse verdrehbaren Kurbelwelle und einer Elektromaschine, deren Rotor um eine zweite, achsparallel zur ersten Drehachse versetzten Drehachse verdrehbar angeordnet ist, einer Drehmomentübertragungseinrichtung mit einer die Brennkraftmaschine und die Elektromaschine wirkverbindenden Drehanbindung und einer zwischen Brennkraftmaschine und Elektromaschine angeordneten Trennkupplung und einem Drehschwingungsdämpfer mit einem an der Kurbelwelle befestigten Eingangsteil und einem entgegen der Wirkung einer Federeinrichtung um die erste Drehachse relativ verdrehbar angeordneten Ausgangsteil.The invention relates to a hybrid drive train with an internal combustion engine with a crankshaft rotatable about a first axis of rotation and an electric machine, the rotor of which is arranged rotatable about a second axis of rotation offset axially parallel to the first axis of rotation, a torque transmission device with a rotary connection that actively connects the internal combustion engine and the electric machine, and one between Internal combustion engine and electric machine arranged separating clutch and a torsional vibration damper with an input part fastened to the crankshaft and an output part arranged so as to be relatively rotatable about the first axis of rotation counter to the action of a spring device.
Hybridantriebsstränge dienen in Kraftfahrzeugen dem Antrieb mittels einer Brennkraftmaschine und einer Elektromaschine. Neben der koaxialen Anordnung der Brennkraftmaschine und der Elektromaschine um eine gemeinsame Drehachse sind insbesondere in bezogen auf die Drehachse engen axialen Bauräumen Hybridantriebsstränge bekannt, bei denen die Brennkraftmaschine und die Elektromaschine achsparallel zueinander angeordnet sind, wobei zwischen den Drehachsen der Kurbelwelle der Brennkraftmaschine und der Drehachse des Rotors der Elektromaschine eine Drehanbindung vorgesehen ist. Zudem sind die Brennkraftmaschine und die Elektromaschine mittels einer Trennkupplung miteinander koppelbar, das heißt, je nach Anforderung eines hybridischen oder reinelektrischen Antriebs, einem Start der Brennkraftmaschine mittels der Elektromaschine, während einer Rekuperation und dergleichen miteinander wirkverbunden oder getrennt.Hybrid drive trains are used in motor vehicles for propulsion by means of an internal combustion engine and an electric machine. In addition to the coaxial arrangement of the internal combustion engine and the electric machine around a common axis of rotation, hybrid drive trains are known in which the internal combustion engine and the electric machine are arranged axially parallel to one another, in particular in narrow axial installation spaces with respect to the axis of rotation, with between the axes of rotation of the crankshaft of the internal combustion engine and the axis of rotation of the A rotary connection is provided for the rotor of the electric machine. In addition, the internal combustion engine and the electric machine can be coupled to one another by means of a separating clutch, that is, depending on the requirements of a hybrid or purely electric drive, starting the internal combustion engine by means of the electric machine, during recuperation and the like, operatively connected or separated from one another.

Aufgabe der Erfindung ist die Weiterbildung eines Hybridantriebsstrangs. Insbesondere ist Aufgabe der Erfindung, einen Hybridantriebsstrang mit achsparallel angeordneter Brennkraftmaschine und Elektromaschine vorzuschlagen, bei dem Drehschwingungsdämpfer, Trennkupplung und ein Drehanbindungsbauteil zur Ankopplung der Elektromaschine eine Baueinheit bilden.The object of the invention is to develop a hybrid drive train. In particular, the object of the invention is to propose a hybrid drive train with an internal combustion engine and electric machine arranged axially parallel, in which the torsional vibration damper, separating clutch and a rotary connection component for coupling the electric machine form a structural unit.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Die von dem Anspruch 1 abhängigen Ansprüche geben vorteilhafte Ausführungsformen des Gegenstands des Anspruchs 1 wieder.The object is achieved by the subject matter of claim 1. The claims dependent on claim 1 reproduce advantageous embodiments of the subject matter of claim 1.
Der vorgeschlagene Hybridantriebsstrang dient dem Antrieb eines Kraftfahrzeugs mittels einer Brennkraftmaschine und einer Elektromaschine, wobei die Kurbelwelle der Brennkraftmaschine um eine erste Drehachse verdrehbar und ein Rotor der Elektromaschine um eine zweite, achsparallel zur ersten Drehachse verdrehbar angeordnet ist. Zwischen der Brennkraftmaschine und einem nachfolgenden Getriebe des Hybridantriebsstrang ist eine Drehmomentübertragungseinrichtung mit einem Drehschwingungsdämpfer, einer Trennkupplung und einem Drehanbindungsbauteil als Baueinheit vorgesehen.The proposed hybrid drive train is used to drive a motor vehicle by means of an internal combustion engine and an electric machine, the crankshaft of the internal combustion engine being arranged to be rotatable about a first axis of rotation and a rotor of the electric machine being arranged to be rotatable about a second axis parallel to the first axis of rotation. A torque transmission device with a torsional vibration damper, a separating clutch and a rotary connection component is provided as a structural unit between the internal combustion engine and a subsequent transmission of the hybrid drive train.
Die Brennkraftmaschine und die Elektromaschine sind mittels der Drehanbindung, beispielsweise eines Kettentriebs, Riementriebs oder einer Zahnradverbindung wie beispielsweise miteinander kämmenden Zahnrädern gekoppelt verbunden. Zur schaltbaren Wirkverbindung zwischen der Brennkraftmaschine und der Elektromaschine ist zwischen diesen die automatisiert geschaltete Trennkupplung vorgesehen, die von einem Betätigungssystem betätigt wird. Die Trennkupplung kann zwangsweise öffnend (normally closed) ausgebildet sein, das heißt die Trennkupplung verbindet die Brennkraftmaschine und die Elektromaschine im nicht betätigten Zustand und wird mittels des Betätigungssystems geöffnet. Alternativ kann die Trennkupplung als zwangsweise schließende Trennkupplung ausgebildet sein, die im nicht betätigten Zustand kein Moment zwischen der Brennkraftmaschine und der Elektromaschine überträgt und mittels des Betätigungssystems geschlossen wird.The internal combustion engine and the electric machine are connected in a coupled manner by means of the rotary connection, for example a chain drive, belt drive or a gear connection such as, for example, intermeshing gears. For the switchable operative connection between the internal combustion engine and the electric machine, the automatically switched separating clutch is provided between them, which is actuated by an actuation system. The separating clutch can be designed to be forced opening (normally closed), that is to say the separating clutch connects the internal combustion engine and the electric machine in the non-actuated state and is opened by means of the actuation system. Alternatively, the separating clutch can be designed as a forcibly closing separating clutch which, in the non-actuated state, does not transmit any torque between the internal combustion engine and the electric machine and is closed by means of the actuation system.
Die Elektromaschine ist getriebeseitig wirkverbunden, so dass bei geöffneter Trennkupplung ein Kraftfahrzeug mit dem Hybridantriebsstrang rein elektrisch angetrieben oder rekuperiert werden kann. Bei geschlossener Trennkupplung kann hybridisch gefahren, bei in einem nachfolgenden Getriebe ausgelegten Gängen die Brennkraftmaschine mittels der Elektromaschine gestartet oder eine Fahrzeugbatterie geladen werden.The electric machine is operatively connected on the transmission side, so that when the separating clutch is disengaged, a motor vehicle with the hybrid drive train can be driven purely electrically or recuperated. When the separating clutch is closed, hybrid driving is possible, the internal combustion engine can be started by means of the electric machine or a vehicle battery can be charged with gears laid out in a subsequent transmission.
Zur Dämpfung von Drehschwingungen der Brennkraftmaschine ist an deren Kurbelwelle der Drehschwingungsdämpfer aufgenommen. Ein mit der Kurbelwelle verbundenes Eingangsteil des Drehschwingungsdämpfers kann als Primärschwungmasse ausgebildet sein. Beispielsweise können mehrere Scheibenteile eine Ringkammer ausbilden, in der eine Federeinrichtung aufgenommen ist. Gegenüber dem Eingangsteil ist um die erste Drehachse begrenzt entgegen der Wirkung der Federeinrichtung verdrehbar ein Ausgangsteil vorgesehen. Die Federeinrichtung kann aus über den Umfang verteilt angeordneten Bogenfedern oder Bogenfederpaketen ineinander geschachtelter Bogenfedern gebildet sein.To dampen torsional vibrations of the internal combustion engine, the Torsional vibration damper added. An input part of the torsional vibration damper connected to the crankshaft can be designed as a primary flywheel. For example, several disc parts can form an annular chamber in which a spring device is received. Opposite the input part, an output part is provided so that it can rotate in a limited manner about the first axis of rotation against the action of the spring device. The spring device can be formed from arc springs or arc spring assemblies of arc springs nested within one another, which are arranged distributed over the circumference.
Um einen axial kompakten Aufbau und als gesamte Baueinheit des Drehschwingungsdämpfers, der Trennkupplung und des motorseitigen Drehanbindungsteils der Drehanbindung vorzusehen, ist die Trennkupplung zwischen einer Ausgangsnabe des Ausgangsteils und einem die Federeinrichtung ausgangsseitig beaufschlagenden Flanschteil in den Drehschwingungsdämpfer integriert und ein der ersten Drehachse zugeordnetes Drehanbindungsteil der Drehanbindung mit der Trennkupplung ausgangsseitig direkt verbunden. Durch die direkte Integrierung, beispielsweise mittels einer festen Verbindung wie Vernietung der Trennkupplung mit dem Flanschteil und die Anbindung des Drehanbindungsbauteils im Drehmomentfluss unmittelbar hinter der Trennkupplung entsteht eine kompakte Baueinheit, die beispielsweise mittels Befestigungsschrauben zwischen dem Eingangsteil des Drehschwingungsdämpfers und der Kurbelwelle als Baueinheit motorseitig befestigt ist. Das Ausgangsteil kann zumindest bei geschlossener Trennkupplung eine Sekundärschwungmasse aufweisen, die zu einem hohen Anteil durch das Trägheitsmoment des Rotors der Elektromaschine über die Drehanbindung gebildet ist. Die Ausgangsnabe bildet beispielsweise mittels einer Innenverzahnung den Abtrieb des Ausgangsteils.In order to provide an axially compact structure and as an entire structural unit of the torsional vibration damper, the separating coupling and the rotary connection part of the rotary connection on the motor side, the separating coupling is integrated into the rotary vibration damper between an output hub of the output part and a flange part acting on the spring device on the output side, and a rotary connection part of the rotary connection assigned to the first axis of rotation directly connected to the disconnect coupling on the output side. The direct integration, for example by means of a fixed connection such as riveting the separating coupling to the flange part, and the connection of the rotary connection component in the torque flow directly behind the separating clutch, creates a compact structural unit that is fastened on the engine side as a unit using fastening screws, for example, between the input part of the torsional vibration damper and the crankshaft . The output part can have a secondary flywheel mass, at least when the separating clutch is closed, which is formed to a large extent by the moment of inertia of the rotor of the electric machine via the rotary connection. The output hub forms the output of the output part, for example by means of internal teeth.
Die Trennkupplung kann als Trockenkupplung mit einer Gegendruckplatte und einer gegenüber dieser von dem Betätigungssystem axial verlagerbaren Anpressplatte ausgebildet sein, wobei zwischen diesen Reibbeläge einer mit der Ausgangsnabe und dem Drehanbindungsteil verbundenen Kupplungsscheibe vorspannbar angeordnet sind. Die Trennkupplung kann als Trockenkupplung oder Nasskupplung ausgebildet sein. Die Trennkupplung kann einen Außenlamellenträger, einen Innenlamellenträger und zwischen diesen ein Lamellenpaket mit abwechselnd mit dem Innenlamellenträger und dem Außenlamellenträger drehfest verbundenen Reiblamellen aufweisen. Das Betätigungssystem der Trennkupplung kann elektromechanisch, elektrohydrostatisch oder elektrohydraulisch ausgebildet sein. Beispielsweise kann von einem elektrisch verlagerten Geberzylinder oder einer hydraulischen Pumpe eine Druckleitung mit Druck beaufschlagt werden, welche einen vor Ort angeordneten Nehmerzylinder, beispielsweise einen um die erste Drehachse angeordneten Nehmerzylinder mit Druck versorgt, so dass dessen Nehmerzylinderkolben mittels eines Betätigungslagers drehentkoppelt ein Betätigungselement wie beispielsweise eine Anpressplatte, ein Betätigungsblech oder dergleichen axial verlagert.The separating clutch can be designed as a dry clutch with a counter-pressure plate and a pressure plate axially displaceable relative to this by the actuation system, with friction linings connected to the output hub and the rotary connection part being arranged in a pretensionable manner between these. The separating clutch can be designed as a dry clutch or a wet clutch. The separating clutch can have an outer disk carrier, an inner disk carrier and, between these, a disk pack with friction disks alternately connected to the inner disk carrier and the outer disk carrier in a rotationally fixed manner. The actuation system of the separating clutch can be designed electromechanically, electrohydrostatically or electrohydraulically. For example, from an electrically displaced master cylinder or a hydraulic pump, pressure can be applied to a pressure line, which supplies a locally arranged slave cylinder, for example a slave cylinder arranged around the first axis of rotation, with pressure so that its slave cylinder piston decouples its rotation by means of an actuating bearing Pressure plate, an actuating plate or the like displaced axially.
Die Lagerung des Eingangsteils des Drehschwingungsdämpfers erfolgt ausschließlich durch zentrierte Aufnahme an der Kurbelwelle. Ausgangsseitig kann beispielsweise die Ausgangsnabe auf einem Lagerflansch des Flanschteils verdrehbar und axial fest, beispielsweise mittels eines Rillenkugellagers, Schrägkugellagers oder dergleichen gelagert sein. Hierdurch werden die mit der Ausgangsnabe verbundenen Bauteile, beispielsweise der ausgangsseitige Teil der Trennkupplung und das motorseitige Drehanbindungsteil gegenüber dem Flanschteil zur ausgangsseitigen Beaufschlagung der Federeinrichtung und Aufnahme des eingangsseitigen Teils der Trennkupplung abgestützt. Hierdurch können Verlagerungen innerhalb der Trennkupplung vermieden und Zugbelastungen der Drehanbindung, beispielsweise eines Riemen- oder Kettentriebs abgestützt werden. Das Ausgangsteil ist dabei mittels der Ausgangsnabe auf der Getriebeseite zentriert. Ein Versatzausgleich zwischen der Getriebeseite und der Kurbelwelle erfolgt innerhalb der Beaufschlagung der Federeinrichtung.The mounting of the input part of the torsional vibration damper takes place exclusively through a centered mounting on the crankshaft. On the output side, for example, the output hub can be rotatably and axially fixed on a bearing flange of the flange part, for example by means of a deep groove ball bearing, angular contact ball bearing or the like. As a result, the components connected to the output hub, for example the output-side part of the separating clutch and the motor-side rotary connection part, are supported against the flange part for the output-side loading of the spring device and receiving the input-side part of the separating clutch. In this way, displacements within the separating clutch can be avoided and tensile loads on the rotary connection, for example a belt or chain drive, can be supported. The output part is centered on the transmission side by means of the output hub. An offset compensation between the transmission side and the crankshaft takes place within the action of the spring device.
In einer alternativen Lagerung kann das Flanschteil verdrehbar auf dem Eingangsteil gelagert sein. Ein Versatzausgleich zwischen der Kurbelwelle und einer Getriebeeingangswelle des Getriebes des Hybridantriebsstrangs findet dabei innerhalb der Trennkupplung statt.In an alternative mounting, the flange part can be rotatably mounted on the input part. An offset compensation between the crankshaft and a transmission input shaft of the transmission of the hybrid drive train takes place within the separating clutch.
Zur Aufnahme des ausgangsseitigen Teils der Trennkupplung und des Drehanbindungsteils ist mit der Ausgangsnabe ein Nabenflansch verbunden, welcher radial au-ßen das Drehanbindungsteil aufweist. Hierbei können das Drehanbindungsteil und der Nabenflansch mit seiner Funktionsfläche, beispielsweise einem axialen Ansatz des Nabenflanschs mit einer Lauffläche für einen Riemen einen Riementrieb oder in anderer Ausbildung des Drehanbindungsteils als Außenverzahnung zur Aufnahme einer Kette einen Kettentrieb oder eine Zahnradverbindung bilden.In order to accommodate the output-side part of the separating clutch and the rotary connection part, a hub flange is connected to the output hub which has the rotary connection part radially on the outside. Here, the rotary connection part and the hub flange with its functional surface, for example an axial attachment of the hub flange with a running surface for a belt, can form a belt drive or, in another embodiment of the rotary connection part as external toothing to accommodate a chain, form a chain drive or a gear connection.
Weiterhin kann je nach Ausbildung der Nasskupplung ein ausgangsseitiger Lamellenträger der Trennkupplung, bevorzugt der Innenlamellenträger einteilig aus dem Nabenflansch gebildet sein.Furthermore, depending on the design of the wet clutch, an output-side disk carrier of the separating clutch, preferably the inner disk carrier, can be formed in one piece from the hub flange.
Das Drehanbindungsteil kann unmittelbar außerhalb des radialen Bauraums der Trennkupplung angeordnet sein. Der axiale Ansatz des Nabenflanschs kann den axialen Bauraum der Trennkupplung axial überschneiden, so dass eine Lauffläche des Drehanbindungsteils die Trennkupplung axial überschneidet und axialer Bauraum eingespart wird.The rotary connection part can be arranged directly outside of the radial installation space of the separating clutch. The axial extension of the hub flange can axially overlap the axial installation space of the separating clutch, so that a running surface of the rotary connection part axially overlaps the separating clutch and axial installation space is saved.
