Description

Die vorliegende Erfindung betrifft eine Getriebeanordnung für ein Fahrzeug mit einem Verbrennungsmotor und zumindest einer elektrischen Maschine als Antrieb gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art.The present invention relates to a transmission arrangement for a vehicle with an internal combustion engine and at least one electrical machine as a drive according to the kind defined in the preamble of claim 1.

Beispielsweise aus der Druckschrift US 5 697 466 A ist ein Hybridfahrzeug mit einem Verbrennungsmotor und einer elektrischen Maschine als Antrieb sowie mit einem hydrodynamischen Drehmomentwandler und einem Planetenradsatz bekannt. Der Verbrennungsmotor ist mit dem hydrodynamischen Drehmomentwandler wirkverbunden, wobei der hydrodynamische Drehmomentwandler über ein Schaltelement mit dem Planetenradsatz wirkverbunden ist.For example from the publication US 5,697,466 A is known a hybrid vehicle with an internal combustion engine and an electric machine as a drive and with a hydrodynamic torque converter and a planetary gear set. The internal combustion engine is operatively connected to the hydrodynamic torque converter, the hydrodynamic torque converter being operatively connected to the planetary gear set via a switching element.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde eine Getriebeanordnung und ein Fahrzeug mit der Getriebeanordnung vorzuschlagen, bei denen eine bauraumgünstige und bezüglich der Ölversorgung optimierte Anordnung realisiert wird.The object of the present invention is to propose a gear arrangement and a vehicle with the gear arrangement in which an arrangement which is space-saving and which is optimized with regard to the oil supply is realized.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 bzw. 10 gelöst. Vorteilhafte und beanspruchte Weiterbildungen ergeben sich aus den Unteransprüchen und der Beschreibung sowie den Zeichnungen.This object is achieved according to the invention by the features of patent claims 1 and 10. Advantageous and claimed further developments result from the subclaims and the description as well as the drawings.

Somit wird eine Getriebeanordnung für ein Kraftfahrzeug mit einem Verbrennungsmotor und zumindest einer elektrischen Maschine als Antrieb vorgeschlagen. Ferner ist ein hydrodynamischer Drehmomentwandler und ein Übersetzungsgetriebe zum Realisieren verschiedener Übersetzungsstufen vorgesehen. Der Verbrennungsmotor ist mit dem hydrodynamischen Drehmomentwandler wirkverbunden, wobei der hydrodynamische Drehmomentwandler über ein Schaltelement mit der elektrischen Maschine wirkverbindbar ist. Um eine bezüglich der Ölversorgung optimierte Anordnung zu schaffen, ist vorgesehen, dass die elektrische Maschine und das Schaltelement in einem Nassraumbereich bzw. Ölraumbereich eines Getriebegehäuses angeordnet sind.A transmission arrangement for a motor vehicle with an internal combustion engine and at least one electrical machine as the drive is thus proposed. A hydrodynamic torque converter and a transmission gear are also provided for realizing different transmission stages. The internal combustion engine is operatively connected to the hydrodynamic torque converter, the hydrodynamic torque converter being operatively connected to the electrical machine via a switching element. In order to create an arrangement that is optimized with regard to the oil supply, it is provided that the electrical machine and the switching element are arranged in a wet room area or oil room area of a transmission housing.

Unter dem Begriff wirkverbunden bzw. wirkverbindbar wird verstanden, dass die Bauteile direkt oder über weitere Bauteile indirekt miteinander verbunden oder verbindbar sind.The term operatively connected or operatively connected is understood to mean that the components are connected or connectable to one another directly or indirectly via further components.

Bei der vorgeschlagenen Getriebeanordnung wird durch die gemeinsame Anordnung der elektrischen Maschine und des Schaltelements in dem Nassraumbereich des Getriebegehäuses eine besonders einfache Ölversorgung beispielsweise für die Kühlung der elektrischen Maschine insbesondere für eine Rotorinnenkühlung der elektrischen Maschine ermöglicht. Zudem wird eine Ölversorgung des Schaltelements insbesondere bei der Verwendung einer sogenannten nassen Kupplung realisiert. Darüber hinaus ergibt sich eine sehr bauraumsparende Anordnung.In the proposed gear arrangement, the common arrangement of the electrical machine and the switching element in the wet area of the gear housing enables a particularly simple oil supply, for example for cooling the electrical machine, in particular for internal rotor cooling of the electrical machine. In addition, an oil supply to the switching element is realized in particular when a so-called wet clutch is used. In addition, there is a very space-saving arrangement.

Dadurch, dass der Nassraumbereich des Getriebegehäuses dem Drehmomentwandler in axialer Richtung nachgeschaltet bzw. angeordnet ist, ergibt sich die Möglichkeit einer Modulbauweise hinsichtlich des Drehmomentwandlers und des restlichen Getriebegehäuses.The fact that the wet area of the transmission housing is arranged or arranged downstream of the torque converter in the axial direction gives the possibility of a modular construction with regard to the torque converter and the rest of the transmission housing.

Bezüglich der Anordnung eines Schwingungsdämpfers bei der vorgeschlagenen Getriebeanordnung besteht die Möglichkeit, den Schwingungsdämpfer bauraumgünstig im Nassraumbereich des Getriebegehäuses gemeinsam mit der elektrischen Maschine und dem Schaltelement unterzubringen. Beispielsweise kann der Schwingungsdämpfer radial innerhalb des Rotors der elektrischen Maschine angeordnet werden. Hierbei ist es besonders von Vorteil, wenn zusätzlich das Schaltelement ebenfalls radial innerhalb der elektrischen Maschine untergebracht wird. Es ist jedoch auch denkbar, dass der Schwingungsdämpfer in das Gehäuse des Drehmomentwandlers integriert wird. Beide Anordnungsmöglichkeiten zeichnen sich durch eine bauraumsparende Bauweise aus.With regard to the arrangement of a vibration damper in the proposed transmission arrangement, there is the possibility of accommodating the vibration damper together with the electrical machine and the switching element in a space-saving manner in the wet area of the transmission housing. For example, the vibration damper can be arranged radially within the rotor of the electrical machine. It is particularly advantageous here if the switching element is also accommodated radially inside the electrical machine. However, it is also conceivable for the vibration damper to be integrated into the housing of the torque converter. Both arrangement options are characterized by a space-saving design.

Dadurch, dass der Drehmomentwandler koaxial zu einer Eingangswelle des Übersetzungsgetriebes angeordnet ist, ergibt sich für die Ölversorgung des Drehmomentwandlers eine besonders konstruktiv einfache Ausführung, in dem Kanäle der Eingangswelle des Übersetzungsgetriebes zur Ölversorgung des Drehmomentwandlers genutzt werden.The fact that the torque converter is arranged coaxially with an input shaft of the transmission gearbox results in a particularly simple design for the oil supply to the torque converter, in which channels of the input shaft of the transmission gearbox are used to supply the torque converter with oil.

Besonders bevorzugt kann die vorgeschlagene Getriebeanordnung bei einem Hybrid-Wandler-Automatikgetriebe mit beispielsweise 8 Gangstufen eingesetzt werden.The proposed transmission arrangement can particularly preferably be used in a hybrid converter automatic transmission with, for example, 8 gear stages.

Ein weiterer Aspekt der vorliegenden Erfüllung sieht vor, dass auch ein Fahrzeug mit der vorbeschriebenen Getriebeanordnung beansprucht wird. Hierbei ergeben sich die vorbeschriebenen Vorteile und weitere Vorteile.Another aspect of the present fulfillment provides that a vehicle with the transmission arrangement described above is also claimed. This results in the advantages described above and other advantages.

Nachfolgend wird die vorliegende Erfindung anhand der Zeichnungen weiter erläutert. Es zeigen:

  • 2nd a sectional view of a second embodiment of the transmission arrangement;
  • 3rd a sectional view of a third embodiment of the transmission arrangement; and
  • 4th is a schematic view of a vehicle with the transmission arrangement.

In den 1 bis 3 sind verschiedene Ausführungsvarianten einer erfindungsgemäßen Getriebeanordnung 16 für ein Fahrzeug 15 lediglich beispielhaft dargestellt.In the 1 to 3rd are different variants of a transmission arrangement according to the invention 16 for a vehicle 15 only shown as an example.

Die Getriebeanordnung 16 umfasst einen Verbrennungsmotor VM und eine elektrische Maschine EM als Antrieb, wobei die elektrische Maschine EM sowohl motorisch als auch generatorisch betrieben werden kann. Ferner umfasst die Getriebeanordnung 16 einen Drehmomentwandler 1 und ein Übersetzungsgetriebe 2 beliebiger Art. Beispielsweise kann auch ein mehrgängiges Automatikgetriebe vorgesehen sein.The gear arrangement 16 includes an internal combustion engine VM and an electrical machine EM as a drive, the electric machine EM can be operated both as a motor and as a generator. The transmission arrangement also includes 16 a torque converter 1 and a transmission gear 2nd of any type. For example, a multi-speed automatic transmission can also be provided.

Der Verbrennungsmotor VM ist mit dem hydrodynamischen Drehmomentwandler 1 wirkverbunden, wobei der hydrodynamische Drehmomentwandler 1 über ein Schaltelement K0 mit der elektrischen Maschine EM wirkverbindbar ist. Das Schaltelement K0 kann beispielsweise als Reibschaltkupplung oder dergleichen ausgeführt sein. Vorzugsweise weist das Schaltelemente K0 einen Innenlamellenträger 3 und einen Außenlamellenträger 4 auf, wobei der Innenlamellenträger mit einem Außenlamellenträger 5 einer Wandlerkupplung WK des Drehmomentwandlers 1 wirkverbunden ist. Ein Innenlamellenträger 6 der Wandlerkupplung WK ist mit dem Verbrennungsmotor VM wirkverbunden. Der Außenlamellenträger 4 des Schaltelements K0 ist mit einem Rotor 7 der elektrischen Maschine EM und mit einer Eingangswelle 8 des Übersetzungsgetriebes 2 wirkverbunden.The internal combustion engine VM is with the hydrodynamic torque converter 1 operatively connected, the hydrodynamic torque converter 1 via a switching element K0 with the electric machine EM is operatively connectable. The switching element K0 can for example be designed as a friction clutch or the like. The switching elements preferably have K0 an inner disk carrier 3rd and an outer disk carrier 4th on, the inner disk carrier with an outer disk carrier 5 a converter clutch WK of the torque converter 1 is connected. An inner disk carrier 6 the converter clutch WK is with the internal combustion engine VM connected. The outer disk carrier 4th of the switching element K0 is with a rotor 7 of the electrical machine EM and with an input shaft 8th of the transmission gear 2nd connected.

Um eine bauraumgünstige und hinsichtlich der Ölversorgung optimierte Anordnung zu realisieren, ist vorgesehen, dass die elektrische Maschine EM und das Schaltelements K0 in einem Nassraumbereich 9 eines Getriebegehäuses 10 quasi als gemeinsamer Ölraumbereich angeordnet sind. Der Drehmomentwandler 1 ist antriebsseitig in axialer Richtung vor dem Nassraumbereich 9 des Getriebegehäuses 10 in einem Trockenraum 20 des Getriebegehäuses 10 angeordnet. Unter dem Begriff Trockenraum wird ein Raum in dem Getriebegehäuse 10 bezeichnet, der gegenüber der Umgebung nicht gegen Ölaustritt abgedichtet ist. Unter dem Begriff Nassraumbereich wird ein Raum in dem Getriebegehäuse 10 bezeichnet, der gegenüber der Umgebung gegen Ölaustritt abgedichtet ist und mit Öl versorgt wird. In order to implement an arrangement that is space-saving and optimized with regard to the oil supply, it is provided that the electrical machine EM and the switching element K0 in a wet room area 9 a gearbox 10th are arranged as a common oil chamber area. The torque converter 1 is on the drive side in the axial direction in front of the wet room area 9 of the gearbox 10th in a drying room 20th of the gearbox 10th arranged. The term drying room is a space in the gear housing 10th designated, which is not sealed against oil leakage from the environment. The term wet room area is a space in the gear housing 10th designated, which is sealed against oil leakage from the environment and is supplied with oil.

Demzufolge sind die elektrische Maschine EM und das Schaltelement funktional und geometrisch hinter dem Drehmomentwandler 1 angeordnet. Zur Schwingungsdämpfung ist ein Schwingungsdämpfer 11 in ein Gehäuse 17 des Drehmomentwandlers 1 bauraumsparend integriert.As a result, the electrical machine EM and the switching element functionally and geometrically behind the torque converter 1 arranged.

Der Schwingungsdämpfer 11 A ist einerseits mit dem Drehmomentwandler 1 und andererseits mit dem Innenlamellenträger 3 des Schaltelements K0 wirkverbunden. Ferner ist vorgesehen, dass der Schwingungsdämpfer 11 A und das Schaltelement K0 radial innerhalb des Rotors 7 der elektrischen Maschine EM bauraumgünstig angeordnet sind. Demzufolge können die notwendigen Betätigungsaktoren auf einfachste Weise hydraulisch betätigt werden, da diese ebenfalls im Nassraumbereich 9 des Getriebegehäuses 10 angeordnet werden können.In the second variant according to 2nd and according to the third variant 3rd is also in the gear arrangement 16 another vibration damper 11 A in the wet room area 9 of the gearbox 10th arranged. The vibration damper 11 A is on the one hand with the torque converter 1 and on the other hand with the inner disk carrier 3rd of the switching element K0 connected. It is also provided that the vibration damper 11 A and the switching element K0 radially inside the rotor 7 of the electrical machine EM are arranged in a space-saving manner. As a result, the necessary actuation actuators can be actuated hydraulically in the simplest way, since they are also in the wet room area 9 of the gearbox 10th can be arranged.

In 2 ist beispielshaft ein sogenannter Zwei-Leitungs- Drehmomentwandler 1 dargestellt. Zur Ölversorgung des Drehmomentwandlers 1 sind demzufolge ein erster Kanal 12 und ein zweiter Kanal 13 vorgesehen, die in der Eingangswelle 8 des Übersetzungsgetriebes 2 angeordnet sind.In 2nd is a so-called two-line torque converter, for example 1 shown. For supplying oil to the torque converter 1 are therefore a first channel 12 and a second channel 13 provided that in the input shaft 8th of the transmission gear 2nd are arranged.

In 3 im Unterschied zur zweiten Ausführungsvariante ein 3-Leitungs-Drehmomentwandler 1 vorgesehen gezeigt. Zur Ölversorgung dieses Drehmomentwandlers 1 sind demzufolge neben dem ersten Kanal 12 und dem zweiten Kanal 13 ein zusätzlicher dritter Kanal 14 erforderlich. Der dritte Kanal 14 ist bei dieser dritten Ausführungsvariante in einem Lagerschild 18 des Getriebegehäuses 10 beispielhaft dargestellt. Es ist jedoch ohne weiteres möglich, diesen zusätzlichen dritten Kanal 14 ebenfalls bauraumgünstig in die Eingangswelle 8 des Übersetzungsgetriebes 2 anzuordnen.In 3rd in contrast to the second embodiment variant, a 3-line torque converter 1 is shown provided. To supply oil to this torque converter 1 are therefore next to the first channel 12 and the second channel 13 an additional third channel 14 required. The third channel 14 is in this third embodiment in a bearing plate 18th of the gearbox 10th shown as an example. However, it is easily possible to add this third channel 14 also space-saving in the input shaft 8th of the transmission gear 2nd to arrange.

Zur Ölversorgung des Nassraumbereiches 9 des Getriebegehäuses 10 ist ein weiterer Kanal 19 in der Eingangswelle 8 des Übersetzungsgetriebes 2 bauraumgünstig vorgesehen.For supplying oil to the wet room area 9 of the gearbox 10th is another channel 19th in the input shaft 8th of the transmission gear 2nd provided in a space-saving manner.

Zur Ölversorgung des Nassraumbereichs 9 und zur Ölzufuhr zum Drehmomentwandler 1 sind demnach drei Kanäle 12, 13, 19 in der Eingangswelle 8 vorgesehen. In der Schnittdarstellung gemäß 2 und 3 können jedoch nur zwei der drei Kanäle explizit dargestellt werden. Zur besseren Verdeutlichung sind daher die Kanalverschlüsse der Kanäle 12 und 19 dargestellt, um die Begrenzung der Kanäle 12 und 19 hervorzuheben.For supplying oil to the wet room area 9 and to supply oil to the torque converter 1 are three channels 12 , 13 , 19th in the input shaft 8th intended. In the sectional view according to 2nd and 3rd However, only two of the three channels can be shown explicitly. For better clarification, the channel closures are therefore the channels 12 and 19th shown to limit the channels 12 and 19th to emphasize.
