Description
Die Erfindung betrifft ein Hybridgetriebe für ein Fahrzeug mit den Merkmalen des Anspruchs 1. Die Erfindung betrifft ferner ein Fahrzeug mit diesem Hybridgetriebe.The invention relates to a hybrid transmission for a vehicle having the features of
Bei modernen Antriebsarchitekturen für Fahrzeuge werden als Traktionsmotoren parallel Elektromotoren und Verbrennungsmotoren eingesetzt. Die Traktionsmomente der Motoren werden über einen gemeinsamen Antriebsstrang zu den angetriebenen Rädern geleitet. In diesen Antriebsarchitekturen ist es somit möglich, das Fahrzeug ausschließlich mit dem Elektromotor, ausschließlich mit dem Verbrennungsmotor oder als Hybrid parallel mit dem Elektromotor und dem Verbrennungsmotor anzutreiben. Diese Funktionen müssen getriebetechnisch umgesetzt werden. Als weitere Herausforderungen für derartige Antriebsarchitekturen ergibt sich, dass für die Elektromotoren und die Verbrennungsmotoren unterschiedliche Drehzahlbereiche der Motoren genutzt werden müssen. Neben den rein funktionellen Anforderungen ergibt sich bei der Auslegung der jeweiligen Getriebe zudem ein Spannungsfeld zwischen einem größtmöglichen Komfort beim Fahren des Hybridfahrzeugs und zugleich dem Wunsch nach einem einfachen und kostengünstigen Aufbau des Getriebes.In modern drive architectures for vehicles, electric motors and internal combustion engines are used in parallel as traction motors. The traction moments of the engines are routed to the driven wheels via a common drivetrain. In these drive architectures, it is thus possible to drive the vehicle exclusively with the electric motor, exclusively with the internal combustion engine or as a hybrid in parallel with the electric motor and the internal combustion engine. These functions must be implemented by transmission technology. As further challenges for such drive architectures it follows that different speed ranges of the motors have to be used for the electric motors and the internal combustion engines. In addition to the purely functional requirements arises in the design of the respective transmission also a field of tension between the greatest possible comfort when driving the hybrid vehicle and at the same time the desire for a simple and inexpensive construction of the transmission.
Es ist Aufgabe der vorliegenden Erfindung, ein Hybridgetriebe für ein Fahrzeug vorzuschlagen, welches eine ausgewogene Lösung in dem Spannungsfeld zwischen Fahrkomfort und Komplexität des Hybridgetriebes bereitstellt.It is an object of the present invention to propose a hybrid transmission for a vehicle, which provides a balanced solution in the field of tension between ride comfort and complexity of the hybrid transmission.
Diese Aufgabe wird durch ein Hybridgetriebe mit den Merkmalen des Anspruchs 1 sowie durch ein Fahrzeug mit den Merkmalen des Anspruchs 10 gelöst. Bevorzugte oder vorteilhafte Ausführungsformen der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung sowie den beigefügten Figuren.

Der Gegenstand der Erfindung ist somit ein Hybridgetriebe, welches für ein Fahrzeug geeignet und/oder ausgebildet ist. Das Fahrzeug ist beispielsweise als ein Personenkraftwagen, Lastkraftwagen, Bus, etc. ausgebildet. Vorzugsweise ist das Hybridgetriebe das einzige Antriebsgetriebe in dem Fahrzeug.The subject of the invention is thus a hybrid transmission which is suitable and / or designed for a vehicle. The vehicle is designed, for example, as a passenger car, truck, bus, etc. Preferably, the hybrid transmission is the only drive gear in the vehicle.
Das Hybridgetriebe ist ausgebildet, mindestens oder genau einen Elektromotor - auch elektrische Maschine zu nennen - und mindestens oder genau eine Verbrennungskraftmaschine - auch Verbrennungsmotor zu nennen - anzukoppeln, um deren Drehmoment als Traktionsmoment zu angetriebenen Rädern des Fahrzeugs zu leiten.The hybrid transmission is designed to couple at least or exactly one electric motor-also called an electric machine-and to couple at least or exactly one internal combustion engine-also called an internal combustion engine-to direct its torque as traction torque to driven wheels of the vehicle.
Das Hybridgetriebe weist eine erste Eingangswelle zur Kopplung mit der Verbrennungskraftmaschine auf. Optional bildet die Verbrennungskraftmaschine einen Bestandteil des Hybridgetriebes. Zwischen der ersten Eingangswelle und der Verbrennungskraftmaschine können beispielsweise Dämpfer oder auch ein Zwischengetriebe angeordnet sein. Optional ist zwischen der ersten Eingangswelle und der Verbrennungskraftmaschine eine Kupplungseinrichtung, insbesondere eine Trennkupplung angeordnet. Alternativ ist die erste Eingangswelle mit einer Kurbelwelle der Verbrennungskraftmaschine stets und/oder dauerhaft drehfest wirkverbunden.The hybrid transmission has a first input shaft for coupling to the internal combustion engine. Optionally, the internal combustion engine forms part of the hybrid transmission. Between the first input shaft and the internal combustion engine, for example, damper or an intermediate gear can be arranged. Optionally, a coupling device, in particular a separating clutch, is arranged between the first input shaft and the internal combustion engine. Alternatively, the first input shaft with a crankshaft of the internal combustion engine always and / or permanently connected non-rotatably.
Das Hybridgetriebe weist eine zweite Eingangswelle zur Kopplung mit dem Elektromotor auf. Optional bildet der Elektromotor einen Bestandteil des Hybridgetriebes. Der Elektromotor kann koaxial zu der zweiten Eingangswelle angeordnet sein, es ist jedoch auch möglich, dass der Elektromotor parallel versetzt oder in einem anderen Winkel zu der zweiten Eingangswelle ausgerichtet ist. In diesen Fällen sind jeweilige Zwischengetriebe vorgesehen. Vorzugsweise ist der Elektromotor stets und/oder dauerhaft drehfest mit der zweiten Eingangswelle wirkverbunden.The hybrid transmission has a second input shaft for coupling to the electric motor. Optionally, the electric motor forms part of the hybrid transmission. The electric motor may be arranged coaxially with the second input shaft, but it is also possible that the electric motor is offset in parallel or oriented at a different angle to the second input shaft. In these cases, respective intermediate gear are provided. Preferably, the electric motor is always and / or permanently non-rotatably operatively connected to the second input shaft.
Die erste und die zweite Eingangswelle sind, insbesondere in Bezug auf deren Rotationsachse, zueinander koaxial ausgerichtet. Insbesondere sind die erste und die zweite Eingangswelle in Flucht zueinander positioniert. Die erste und die zweite Eingangswelle sind vorzugsweise nebeneinander angeordnet.The first and the second input shaft are, in particular with respect to their axis of rotation, aligned coaxially with each other. In particular, the first and the second input shaft are positioned in alignment with each other. The first and the second input shaft are preferably arranged next to one another.
Ferner weist das Hybridgetriebe eine Ausgangswelle auf, wobei die Ausgangswelle beispielsweise mit einer Differentialeinrichtung zur Verteilung des durch geleiteten Antriebsdrehmoments an die angetriebenen Räder wirkverbunden oder getriebetechnisch gekoppelt sein kann. Die Ausgangswelle, insbesondere die Rotationsachse der Ausgangswelle, ist parallel, insbesondere parallel versetzt, zu der ersten und/oder zweiten Eingangswelle angeordnet. In dieser Anordnung ergibt sich ein sehr kompakter Aufbau des Hybridgetriebes.Further, the hybrid transmission has an output shaft, wherein the output shaft, for example, with a differential device for distributing the guided by driving torque to the driven wheels operatively connected or coupled by transmission technology. The output shaft, in particular the axis of rotation of the output shaft, is arranged parallel, in particular offset in parallel, to the first and / or second input shaft. In this arrangement results in a very compact construction of the hybrid transmission.
Es ist darauf hinzuweisen, dass nachfolgend die Bezeichnung „Sx“, wobei x eine beliebige Indexzahl sein kann, ausschließlich zur Zuordnung und Identifikation der jeweiligen Komponenten verwendet wird. Unter getriebetechnisch verbinden wird insbesondere eine Wirkverbindung verstanden, über die ein Drehmoment von der einen Welle zu der anderen Welle übertragen werden kann. It should be noted that, hereinafter, the term "Sx", where x may be any index number, is used exclusively for the assignment and identification of the respective components. Under gear technology connect is understood in particular an operative connection, via which a torque can be transmitted from one shaft to the other shaft.

Es ist eine Überlegung der Erfindung, ein Hybridgetriebe vorzuschlagen, welches mindestens oder genau sechs oder sieben verbrennungsmotorische Gänge (mit unterschiedlichen Übersetzungen) und mindestens oder genau zwei oder drei elektromotorische Gänge (mit unterschiedlichen Übersetzungen) aufweist, wobei die verbrennungsmotorischen Gänge auch hybridtechnisch betrieben werden können, und zugleich einen einfachen konstruktiven Aufbau mit wenigen Komponenten hat. Somit ist eine Vielzahl von Funktionen in dem Hybridgetriebe umgesetzt, ohne dass die Anzahl der Komponenten zu hoch ist.It is a consideration of the invention to propose a hybrid transmission having at least or exactly six or seven internal combustion engine gears (with different ratios) and at least or exactly two or three electromotive gears (with different ratios), wherein the internal combustion engine gears can also be operated hybrid , and at the same time has a simple structural design with few components. Thus, a variety of functions are implemented in the hybrid transmission, without the number of components is too high.
Bei einer bevorzugten Weiterbildung der Erfindung weist das Hybridgetriebe eine Kupplungseinrichtung auf, welche zur An- und/oder Abkopplung der Verbrennungskraftmaschine an die erste Eingangswelle ausgebildet ist. Besonders bevorzugt ist die Kupplungseinrichtung als eine Reibkupplung, insbesondere als eine Lamellenkupplung, ausgebildet. In einer möglichen konstruktiven Ausgestaltung ist eine Kurbelwelle der Verbrennungskraftmaschine koaxial zu der ersten Eingangswelle ausgerichtet. Die Kupplungseinrichtung, insbesondere die Reibkupplung, kann in einfacher Weise zwischen der Verbrennungskraftmaschine und der ersten Eingangswelle angeordnet werden. Durch die Kupplungseinrichtung wird erreicht, dass nicht nur mindestens oder genau sechs oder sieben hybridtechnische Gänge umgesetzt werden können, sondern dass in jedem der hybridtechnischen Gänge die Verbrennungskraftmaschine in Abhängigkeit des Betriebszustands der Kupplungseinrichtung (offen / geschlossen) angekoppelt oder abgekoppelt werden kann. Somit können die sechs oder sieben Gänge auch als rein elektromotorische Gänge betrieben oder gestützt werden.In a preferred embodiment of the invention, the hybrid transmission has a coupling device, which is designed to connect to and / or decouple the internal combustion engine to the first input shaft. Particularly preferably, the coupling device is designed as a friction clutch, in particular as a multi-plate clutch. In a possible structural embodiment, a crankshaft of the internal combustion engine is aligned coaxially with the first input shaft. The coupling device, in particular the friction clutch, can be arranged in a simple manner between the internal combustion engine and the first input shaft. By the coupling device is achieved that not only at least or exactly six or seven hybrid technical gears can be implemented, but that in each of the hybrid technical gears, the internal combustion engine depending on the operating state of the clutch device (open / closed) can be coupled or disconnected. Thus, the six or seven gears can also be operated or supported as purely electromotive gears.
Bei einer bevorzugten Weiterbildung der Erfindung ist das Doppelzahnrad als ein Losrad auf der Ausgangswelle ausgebildet. Dadurch wird es ermöglicht, dass das Doppelzahnrad als ein Brückenglied zwischen Komponenten der ersten und der zweiten Eingangswelle angeordnet werden kann.In a preferred embodiment of the invention, the double gear is formed as a loose wheel on the output shaft. Thereby, it is possible that the double gear can be arranged as a bridge member between components of the first and the second input shaft.

Somit ist es möglich, jeden beliebigen der Vorwärtsgänge zwischen einer hybridtechnischen Betriebsweise und einer rein elektrischen Betriebsweise zu schalten.Preferably, the method comprises a method step, wherein starting from one of the forward gears ICE1, ICE2, ICE3, ICE4, ICE5, ICE6 and / or ICE7 via the clutch device, the internal combustion engine is decoupled to drive the vehicle purely electrically. Thus, it is possible to switch any of the forward gears between a hybrid-technical mode of operation and a purely electrical mode of operation.
