Definitions

  • Hybrid gear with axially short brake-clutch combination as well as drive train
  • the invention relates to a hybrid transmission for a motor vehicle drive train, with a housing forming a wet area, an electrical machine, a transmission device arranged to at least one part in the wet area and coupled to a rotor of the electrical machine's, a clutch arranged outside the wet area and a also arranged outside the wet area, with a component of the clutch or the transmission device in engagement ble blocking device.
  • the invention also relates to a drive train with the hybrid transmission.
  • the blocking device is designed as a brake that acts in a form-locking or frictional-locking manner. Since the blocking device is only operated slightly in the slip mode during operation and almost exclusively needs to implement a holding function, the blocking device can be implemented in a particularly compact manner.
  • the blocking device has a holding part (preferably designed as a brake caliper) which has a limited extent in the circumferential direction and is fixed to the housing.
  • the blocking device and clutch are nested axially into one another as cleverly as possible.
  • the clutch is preferably used acting between at least two components of the Gereteein direction.
  • a carrier connected to a transmission shaft which directly has a support area of the blocking device (which interacts with the at least one holding part), which is preferably designed as a brake disk. Accordingly, it is also expedient if the carrier directly receives a coupling cover of the coupling and / or has a friction surface that interacts with a coupling disc of the coupling. This further simplifies the structure.
  • vibration damper is attached to the carrier.
  • This vibration damper (for example designed as a two-mass flywheel) is preferably used to act between an input that can be further connected to an internal combustion engine and the carrier.
  • a clutch disc of the clutch is non-rotatably connected to a ring gear of a planetary gear stage of the gear unit.
  • the ring gear is at the same time preferably connected to the rotor of the electrical machine (permanently) in a rotationally fixed manner.
  • the invention relates to a drive train for a hybrid motor vehicle, with an internal combustion engine and a hybrid transmission according to the invention coupled on the input side to the internal combustion engine and on the output side with at least one output shaft according to at least one of the previously described embodiments.

Description

Hybridqetriebe mit axial kurzbauender Brems-Kupplunqs-Kombination; sowie Antriebsstranq Hybrid gear with axially short brake-clutch combination; as well as drive train
Die Erfindung betrifft ein Hybridgetriebe für einen Kraftfahrzeugantriebsstrang, mit ei nem einen Nassraum bildenden Gehäuse, einer elektrischen Maschine, einer zu zu mindest einem Teil in dem Nassraum angeordneten und mit einem Rotor der elektri schen Maschine gekoppelten Getriebeeinrichtung, einer außerhalb des Nassraums angeordneten Kupplung sowie einer ebenfalls außerhalb des Nassraums angeordne ten, mit einem Bestandteil der Kupplung oder der Getriebeeinrichtung in Eingriff bring baren Blockiereinrichtung. Auch betrifft die Erfindung einen Antriebsstrang mit dem Hybridgetriebe. The invention relates to a hybrid transmission for a motor vehicle drive train, with a housing forming a wet area, an electrical machine, a transmission device arranged to at least one part in the wet area and coupled to a rotor of the electrical machine's, a clutch arranged outside the wet area and a also arranged outside the wet area, with a component of the clutch or the transmission device in engagement ble blocking device. The invention also relates to a drive train with the hybrid transmission.
Von gattungsgemäßen Getrieben des Standes der Technik ist es prinzipiell bereits be kannt, Kupplungen oder Bremsen in einen Trockenraum zu verlegen, um die im Be trieb auftretenden Schleppverluste zu reduzieren. Beispielhaft ist hierfür die DE 10 2017 124 074 A1 zu nennen. Weiterer Stand der Technik ist mit der US 2019/0275878 A1 sowie der WO 2019/141561 A1 bekannt. From generic transmissions of the prior art, it is in principle already be known to relocate clutches or brakes in a dry room in order to reduce the drag losses that occur during operation. DE 10 2017 124 074 A1 is an example of this. Further prior art is known from US 2019/0275878 A1 and WO 2019/141561 A1.
Ein Nachteil der aus dem Stand der Technik bekannten Getriebesysteme besteht je doch darin, dass diese eine relativ große axiale Länge aufweisen. Dadurch ist die Ein setzbarkeit deutlich beschränkt. A disadvantage of the transmission systems known from the prior art is, however, that they have a relatively large axial length. As a result, the applicability is clearly limited.
Es ist damit Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik be kannten Nachteile zu beheben und insbesondere ein axial kurzbauendes Hybridge triebe mit möglichst geringen Schleppverlusten zur Verfügung zu stellen. It is therefore the object of the present invention to remedy the disadvantages known from the prior art and, in particular, to provide an axially short hybrid drive with the lowest possible drag losses.
Dies wird erfindungsgemäß dadurch gelöst, dass sich die Blockiereinrichtung und die Kupplung zumindest teilweise in axialer Richtung überlappen. This is achieved according to the invention in that the blocking device and the clutch at least partially overlap in the axial direction.
Durch diese Anordnung werden die außerhalb des Nassraums angeordnete Kupplung und Blockiereinrichtung möglichst geschickt miteinander verschachtelt, sodass die Länge das Hybridgetriebe deutlich reduziert wird. Weitergehende vorteilhafte Ausführungen sind mit den Unteransprüchen beansprucht und nachfolgend näher erläutert. With this arrangement, the clutch and locking device arranged outside the wet area are nested with one another as cleverly as possible, so that the length of the hybrid transmission is significantly reduced. Further advantageous embodiments are claimed with the subclaims and explained in more detail below.
Demnach ist es vorteilhaft, wenn die Blockiereinrichtung als eine formschlüssig oder reibkraftschlüssig wirkende Bremse ausgebildet ist. Da die Blockiereinrichtung im Be trieb nur geringfügig im Schlupfmodus betrieben werden und fast ausschließlich eine Haltefunktion umsetzen braucht, kann die Blockiereinrichtung besonders kompakt um gesetzt werden. Accordingly, it is advantageous if the blocking device is designed as a brake that acts in a form-locking or frictional-locking manner. Since the blocking device is only operated slightly in the slip mode during operation and almost exclusively needs to implement a holding function, the blocking device can be implemented in a particularly compact manner.
Auch ist es von Vorteil, wenn die Blockiereinrichtung ein, eine begrenzte / beschränkte Erstreckung in Umfangsrichtung aufweisendes und gehäusefest angebrachtes Halte teil (vorzugsweise als Bremssattel ausgebildet) aufweist. It is also advantageous if the blocking device has a holding part (preferably designed as a brake caliper) which has a limited extent in the circumferential direction and is fixed to the housing.
Des Weiteren ist es zweckdienlich, wenn mehrere Halteteile in Umfangsrichtung ver teilt angeordnet sind, sodass die Bremskraft / Haltekraft der Blockiereinrichtung mög lichst gleichmäßig am Umfang verteilt ist. It is also useful if several holding parts are arranged in the circumferential direction so that the braking force / holding force of the blocking device is distributed as evenly as possible on the circumference.
Ist das zumindest eine Halteteil radial außerhalb sowie axial auf gleicher Höhe mit zu mindest einem Abschnitt, vorzugsweise einem Reibelement, einem Gegendruckplat tenbereich, einer Anpressplatte und / oder einer Tellerfeder der Kupplung angeordnet, werden Blockiereinrichtung und Kupplung möglichst geschickt axial ineinander ver schachtelt. If the at least one holding part is arranged radially outside and axially at the same level with at least one section, preferably a friction element, a counterpressure plate area, a pressure plate and / or a plate spring of the clutch, the blocking device and clutch are nested axially into one another as cleverly as possible.
Die Kupplung ist bevorzugt zwischen zumindest zwei Bestandteilen der Getriebeein richtung wirkend eingesetzt. The clutch is preferably used acting between at least two components of the Getriebein direction.
Des Weiteren ist es zweckmäßig, wenn ein mit einer Getriebewelle verbundener Trä ger vorhanden ist, der unmittelbar einen (mit dem zumindest einen Halteteil zusam menwirkenden) Abstützbereich der Blockiereinrichtung, der vorzugsweise als eine Bremsscheibe ausgebildet ist, aufweist. Demnach ist es auch zweckmäßig, wenn der Träger unmittelbar einen Kupplungsde ckel der Kupplung aufnimmt und / oder eine mit einer Kupplungsscheibe der Kupplung zusammenwirkende Reibfläche aufweist. Dadurch wird der Aufbau weiter vereinfacht. Furthermore, it is expedient if there is a carrier connected to a transmission shaft which directly has a support area of the blocking device (which interacts with the at least one holding part), which is preferably designed as a brake disk. Accordingly, it is also expedient if the carrier directly receives a coupling cover of the coupling and / or has a friction surface that interacts with a coupling disc of the coupling. This further simplifies the structure.
Des Weiteren ist es vorteilhaft, wenn ein Schwingungsdämpfer an dem Träger befes tigt ist. Bevorzugt ist dieser (bspw. als Zweimassenschwungrad ausgebildete) Schwin gungsdämpfer zwischen einem mit einer Verbrennungskraftmaschine weiter verbind baren Eingang und dem Träger wirkend eingesetzt. It is also advantageous if a vibration damper is attached to the carrier. This vibration damper (for example designed as a two-mass flywheel) is preferably used to act between an input that can be further connected to an internal combustion engine and the carrier.
Zudem ist es zweckmäßig, wenn eine Kupplungsscheibe der Kupplung mit einem Hohlrad einer Planetengetriebestufe der Getriebeeinrichtung drehfest verbunden ist. Das Hohlrad ist zugleich bevorzugt mit dem Rotor der elektrischen Maschine (perma nent) drehfest verbunden. In addition, it is expedient if a clutch disc of the clutch is non-rotatably connected to a ring gear of a planetary gear stage of the gear unit. The ring gear is at the same time preferably connected to the rotor of the electrical machine (permanently) in a rotationally fixed manner.
Auch ist es zweckmäßig, wenn ein Kupplungsgehäuse der Kupplung mit einem Son nenrad der Planetengetriebestufe drehfest verbunden ist. It is also useful if a clutch housing of the clutch is rotatably connected to a Son nenrad of the planetary gear stage.
Zudem betrifft die Erfindung einen Antriebsstrang für ein hybridisch angetriebenes Kraftfahrzeug, mit einer Verbrennungskraftmaschine und einem eingangsseitig mit der Verbrennungskraftmaschine sowie ausgangsseitig mit zumindest einer Abtriebswelle gekoppelten erfindungsgemäßen Hybridgetriebe nach zumindest einer der zuvor be schriebenen Ausführungen. In addition, the invention relates to a drive train for a hybrid motor vehicle, with an internal combustion engine and a hybrid transmission according to the invention coupled on the input side to the internal combustion engine and on the output side with at least one output shaft according to at least one of the previously described embodiments.
Mit anderen Worten ausgedrückt, ist somit erfindungsgemäß eine kurzbauende Brems-Kupplungs-Kombination in einem Trockenraum zur Senkung der Schleppver luste umgesetzt. Es wird bevorzugt vorgeschlagen, eine entsprechende Bremse (Blo ckiereinrichtung) vorzusehen, die eine möglichst kurze axiale Ausdehnung hat. Er reicht wird das, indem die Bremse aus einem oder mehreren Bremssätteln ausgeführt ist. Diese beanspruchen keinen rundum verlaufenden Bauraum und können mit Lage raugen und dem Differenzial verschachtelt werden. In other words, according to the invention, a short brake-clutch combination is implemented in a dry room to reduce Schleppver losses. It is preferably proposed to provide a corresponding brake (blocking device) which has an axial extension that is as short as possible. This is enough if the brake is made up of one or more brake calipers. These do not take up any all-round installation space and can be nested with the position and the differential.
Die Erfindung wird nun nachfolgend anhand von Figuren näher erläutert. Es zeigen: The invention will now be explained in more detail below with reference to figures. Show it:

Die Figuren sind lediglich schematischer Natur und dienen ausschließlich dem Ver ständnis der Erfindung. Die gleichen Elemente sind mit denselben Bezugszeichen ver sehen. The figures are only of a schematic nature and are used exclusively for understanding the invention. The same elements are provided with the same reference numerals.
Die Fig. 2 lässt zunächst einen bevorzugten Einsatzbereich eines erfindungsgemäßen Hybridgetriebes 1 erkennen. Das Hybridgetriebe 1 ist bevorzugt in einem Antriebs strang 40 eines Kraftfahrzeuges eingesetzt. Eine Verbrennungskraftmaschine 36 ist mit einem Eingang 37 des Hybridgetriebes 1 verbunden. Ein Ausgang 38 des Hyb ridgetriebes 1 ist über ein Differenzial 41 mit zwei Abtriebswellen 39a, 39b einer Achse des Kraftfahrzeuges verbunden. Dem Hybridgetriebe 1 sind eine elektrische Maschine 4 und eine Getriebeeinrichtung 6 unmittelbar zugeordnet. FIG. 2 initially shows a preferred area of application of a hybrid transmission 1 according to the invention. The hybrid transmission 1 is preferably used in a drive train 40 of a motor vehicle. An internal combustion engine 36 is connected to an input 37 of the hybrid transmission 1. An output 38 of the hybrid transmission 1 is connected via a differential 41 to two output shafts 39a, 39b of an axle of the motor vehicle. An electric machine 4 and a transmission device 6 are directly assigned to the hybrid transmission 1.
Mit Fig. 1 ist der nähere Aufbau des Hybridgetriebes 1 veranschaulicht. Das Hybridge triebe 1 weist demnach ein Gehäuse 3 auf, das einen Nassraum 2 umschließt. Unter einem Nassraum 2 ist ein im Betrieb zumindest teilweise mit Öl gefüllter oder von Öl durchflossener Raum bezeichnet. Innerhalb des Gehäuses 3 / des Nassraums 2 ist eine elektrische Maschine 4 angeordnet. With Fig. 1, the more detailed structure of the hybrid transmission 1 is illustrated. The hybrid drive 1 accordingly has a housing 3 which encloses a wet room 2. A wet room 2 denotes a room which is at least partially filled with oil or through which oil flows during operation. An electrical machine 4 is arranged within the housing 3 / the wet room 2.
Die elektrische Maschine 4 weist auf typische Weise einen fest im Gehäuse 3 aufge nommenen Stator 23 und einen relativ zu dem Stator 23 drehbar angeordneten Rotor 5 auf. Der Rotor 5 steht mit einer Getriebeeinrichtung 6 in Wirkzusammenhang. Die Getriebeeinrichtung 6 weist eine Planetengetriebestufe 20 auf. In dieser Ausführung ist der Rotor 5 mit einem Hohlrad 19 der Planetengetriebestufe 20 permanent drehfest verbunden. Ein Sonnenrad 22 der Planetengetriebestufe 20 bildet unmittelbar eine Getriebewelle 12 aus, die als Getriebeeingangswelle fungiert. Mehrere in Umfangsrichtung verteilt angeordnete Planetenräder 25 sind auf einem Planetenträger 26 der Planetengetriebestufe 20 drehbar aufgenommen. In dieser Aus führung ist der Planetenträger 26 weiter mit einer in Fig. 1 ebenfalls teilweise zu er kennenden Zwischenwelle 27 der Getriebeeinrichtung 6 gekoppelt. The electric machine 4 typically has a stator 23 fixedly mounted in the housing 3 and a rotor 5 which is rotatably arranged relative to the stator 23. The rotor 5 is in operative connection with a transmission device 6. The transmission device 6 has a planetary gear stage 20. In this embodiment, the rotor 5 is permanently non-rotatably connected to a ring gear 19 of the planetary gear stage 20. A sun gear 22 of the planetary gear stage 20 directly forms a gear shaft 12 which functions as a gear input shaft. A plurality of planet gears 25 distributed in the circumferential direction are rotatably received on a planet carrier 26 of the planetary gear stage 20. In this implementation, the planet carrier 26 is further coupled to an intermediate shaft 27 of the transmission device 6 which is also partially known in FIG. 1.
Die Getriebewelle 12 durchdringt eine Öffnung 28 in dem Gehäuse 3 und ragt von dem Nassraum 2 nach außen aus dem Gehäuse 3 hinaus und in einen Trockenraum 29 hinein. Der Trockenraum 29 ist auf typische Weise zumindest teilweise zur Umge bung hin geöffnet und teilweise von dem Gehäuse 3 mit umschlossen. Die Getriebe welle 12 somit mit einem Bestandteil, insbesondere mit ihrem mit den Planetenrädern 25 in Zahneingriff befindlichen Bestandteil, innerhalb des Nassraums 2 angeordnet und mit einem anderen Bestandteil außerhalb des Nassraums 2, d. h. innerhalb des Trockenraums 29 angeordnet. The gear shaft 12 penetrates an opening 28 in the housing 3 and protrudes from the wet space 2 to the outside of the housing 3 and into a dry space 29. The drying space 29 is typically at least partially open to the environment and partially enclosed by the housing 3. The transmission shaft 12 thus with one component, in particular with its component located in meshing engagement with the planetary gears 25, is arranged inside the wet room 2 and with another component outside the wet room 2, d. H. arranged within the drying room 29.
In dem Trockenraum 29 sind eine Kupplung 9 sowie eine Blockiereinrichtung 10 ange ordnet. Die Kupplung 9 und die Blockiereinrichtung 10 dienen auf typische Weise zum Schalten der Getriebeeinrichtung 6 zwischen zumindest zwei unterschiedlichen Be triebsmodi. In diesem Zusammenhang sei der Vollständigkeit halber auch darauf hin gewiesen, dass die gegenständlich verwendeten Richtungsangaben axial / axiale Richtung, radial / radiale Richtung und Umfangsrichtung in Bezug auf die Drehachse 35 zu setzen sind. Unter axial / axiale Richtung ist demnach eine Richtung entlang der Drehachse 35, unter radial / radiale Richtung eine Richtung senkrecht zu der Dreh achse 35 und unter Umfangsrichtung eine Richtung entlang einer koaxial zur Dreh achse 35 verlaufenden Kreislinie zu verstehen. In the drying room 29, a clutch 9 and a blocking device 10 are arranged. The clutch 9 and the blocking device 10 are used in a typical manner to switch the transmission device 6 between at least two different operating modes. In this context, for the sake of completeness, it should also be pointed out that the directional information used here is to be set in relation to the axis of rotation 35: axial / axial direction, radial / radial direction and circumferential direction. Under axial / axial direction is accordingly a direction along the axis of rotation 35, under radial / radial direction a direction perpendicular to the axis of rotation 35 and under circumferential direction a direction along a circular line coaxially to the axis of rotation 35.
Die Kupplung 9 ist seitens ihres ersten Kupplungsbestandteils 30a mit einem ersten Getriebebestandteil 7 in Form der Getriebewelle 12 drehfest verbunden. Ein zweiter Kupplungsbestandteil 30b der Kupplung 9 ist mit einem zweiten Getriebebestandteil 8 in Form des Hohlrades 19 drehfest verbunden. Somit ist die Kupplung 9 zwischen der Getriebewelle 12 und dem Hohlrad 19 wirkend eingesetzt. In einer geschlossenen Stellung der Kupplung 9 sind Getriebewelle 12 und Hohlrad 19 miteinander drehtest verbunden, während sie in einer geöffneten Stellung der Kupplung 9 frei relativ zuei nander verdrehbar sind. On the part of its first clutch component 30a, the clutch 9 is connected in a rotationally fixed manner to a first transmission component 7 in the form of the transmission shaft 12. A second clutch component 30b of the clutch 9 is connected in a rotationally fixed manner to a second transmission component 8 in the form of the ring gear 19. Thus, the clutch 9 is between the Gear shaft 12 and the ring gear 19 used to act. In a closed position of the clutch 9, the transmission shaft 12 and ring gear 19 are connected to one another in a rotationally test, while in an open position of the clutch 9 they can be freely rotated relative to one another.
Die Kupplung 9 ist in dieser Ausführung als Reibkupplung, nämlich als eine Einschei benkupplung, realisiert. Die Kupplung 9 weist ein Kupplungsgehäuse 21 auf, das eine Anpressplatte 31 axial verschiebbar, jedoch drehtest, aufnimmt. Das Kupplungsge häuse 21 weist einen Kupplungsdeckel 15 auf, der eine Tellerfeder 32 schwenkbar la gert. Kupplungsgehäuse 21 und Anpressplatte 31 sind folglich Teil eines ersten Kupp lungsbestandteils 30a. Axial zwischen der Anpressplatte 31 und einem Gegendruck plattenbereich 33 des Kupplungsgehäuses 21 , welcher Gegendruckplattenbereich 33 zugleich eine Reibfläche 17 unmittelbar ausbildet, ist die Kupplungsscheibe 16 einge setzt. Die Kupplungsscheibe 16 ist direkt mit dem Hohlrad 19 verbunden. Die Kupp lungsscheibe 16 bildet einen Teil eines zweiten Kupplungsbestandteils 30b. In this embodiment, the clutch 9 is implemented as a friction clutch, namely as a single clutch. The clutch 9 has a clutch housing 21 which accommodates a pressure plate 31 such that it can be axially displaced but is rotatable. The clutch housing 21 has a clutch cover 15 which pivots a plate spring 32 la Gert. The clutch housing 21 and pressure plate 31 are consequently part of a first clutch component 30a. Axially between the pressure plate 31 and a counterpressure plate area 33 of the clutch housing 21, which counterpressure plate area 33 also forms a friction surface 17 directly, the clutch disc 16 is inserted. The clutch disk 16 is directly connected to the ring gear 19. The clutch disc 16 forms part of a second clutch component 30b.
Der erste Kupplungsbestandteil 30a weist zudem einen Träger 13 auf. Dieser Träger 13 bildet einen stoffeinteiligen Bestandteil des Kupplungsgehäuses 21 , insbesondere den Gegendruckplattenbereich 33 mit der Reibfläche 17, aus. Zugleich nimmt der Trä ger 13 den Kupplungsdeckel 15 auf. Der Kupplungsdeckel 15 ist an dem Träger 13 befestigt. Des Weiteren ist der Träger 13 mit einem Schwingungsdämpfer 18, hier in Form eines Zweimassenschwungrades, weiter verbunden. Der Träger 13 weist zu die sem Zwecke eine Steckverzahnung 44 auf. Der Schwingungsdämpfer 18 ist auf typi sche Weise im Betrieb eingangsseitig mit einer Ausgangswelle 34 der Verbrennungs kraftmaschine 36 weiter verbunden. Ausgangsseitig ist der Schwingungsdämpfer 18 direkt an den Träger 13 angebunden. The first coupling component 30a also has a carrier 13. This carrier 13 forms an integral part of the clutch housing 21, in particular the counter-pressure plate area 33 with the friction surface 17. At the same time, the Trä ger 13 takes the clutch cover 15 on. The clutch cover 15 is attached to the carrier 13. Furthermore, the carrier 13 is further connected to a vibration damper 18, here in the form of a two-mass flywheel. The carrier 13 has a spline 44 for this purpose. The vibration damper 18 is typically connected on the input side to an output shaft 34 of the internal combustion engine 36 during operation. On the output side, the vibration damper 18 is connected directly to the carrier 13.
Dadurch, dass der Träger 13 (über eine Nabe 43) mit der Getriebewelle 12 direkt ver bunden ist, ist die Verbrennungskraftmaschine 36 im Betrieb permanent mit der Ge triebewelle 12 drehfest gekoppelt. Erfindungsgemäß ist die Blockiereinrichtung 10 so relativ zu der Kupplung 9 angeord net, dass sie diese in axialer Richtung überragt / in axialer Richtung überlappend mit dieser angeordnet ist. Because the carrier 13 is directly connected to the transmission shaft 12 (via a hub 43), the internal combustion engine 36 is permanently coupled to the transmission shaft 12 in a rotationally fixed manner during operation. According to the invention, the blocking device 10 is angeord net relative to the clutch 9 in such a way that it projects beyond it in the axial direction / is arranged to overlap with it in the axial direction.
In dieser Ausführung ist ein Bestandteil der Blockiereinrichtung 10 durch den ersten Kupplungsbestandteil 30a, nämlich den Träger 13, mit ausgebildet. Der Träger 13 weist zu diesem Zwecke einen scheibenförmigen Abstützbereich 14 auf. Da die Blo ckiereinrichtung 10 in dieser Ausführung als Bremse realisiert ist, ist der Abstützbe reich 14 auch als Bremsscheibe bezeichnet. Der Abstützbereich 14 steht in radialer Richtung nach außen über die Anpressplatte 31 und den Gegendruckplattenbereich 33 hinaus. In this embodiment, a component of the blocking device 10 is also formed by the first coupling component 30a, namely the carrier 13. For this purpose, the carrier 13 has a disk-shaped support area 14. Since the blocking device 10 is implemented as a brake in this embodiment, the support area 14 is also referred to as a brake disc. The support area 14 projects outward in the radial direction beyond the pressure plate 31 and the counter-pressure plate area 33.
Der Abstützbereich 14 befindet sich in Wirkzusammenhang mit mehreren in Umfangs richtung verteilt angeordneten Halteteilen 11 der Blockiereinrichtung 10. Die Halteteile 11 sind als Bremssattel umgesetzt. Die Halteteile 11 weisen eine in Umfangsrichtung beschränkte Erstreckung auf. Insbesondere erstrecken sich die jeweiligen Halteteile 11 bevorzugt um weniger als 30° in Umfangsrichtung um eine zentrale Drehachse 35 der Getriebewelle 12. The support area 14 is in operative connection with a plurality of holding parts 11 of the blocking device 10, which are distributed in the circumferential direction. The holding parts 11 are implemented as brake calipers. The holding parts 11 have a limited extent in the circumferential direction. In particular, the respective holding parts 11 preferably extend by less than 30 ° in the circumferential direction around a central axis of rotation 35 of the transmission shaft 12.
Wie bspw. in Fig. 1 zu einer Unterseite erkennbar, ist das jeweilige Halteteil 11 axial zwischen dem Gehäuse 3 und dem Schwingungsdämpfer 18 untergebracht. Insbe sondere befindet sich das Halteteil 11 in axialer Richtung auf Höhe mit dem Kupp lungsdeckel 15, der Tellerfeder 32 sowie der Anpressplatte 31 . Des Weiteren befindet sich das Halteteil 11 axial neben in einem durch das Gehäuse 3 mit ausgebildeten, zur Lagerung des Rotors 5 eingesetzten Lageraugenbereich 24. Auch befindet sich das Halteteil 11 in Bezug auf die Drehachse 35 radial versetzt zu dem Differenzial 41. As can be seen, for example, on an underside in FIG. 1, the respective holding part 11 is accommodated axially between the housing 3 and the vibration damper 18. In particular, the holding part 11 is located in the axial direction level with the coupling cover 15, the plate spring 32 and the pressure plate 31. Furthermore, the holding part 11 is located axially next to a bearing eye area 24 which is also formed by the housing 3 and is used to support the rotor 5.
Alternativ zu der Ausbildung der Blockiereinrichtung 10 als reibkraftschlüssig wirkende Bremse, ist diese in weiteren Ausführungen als formschlüssig wirkende Blockierein richtung 10, etwa als Klauenbremse, umgesetzt. Die Blockiereinrichtung 10 ist jedoch stets derart ausgebildet, dass sie in einem aktivierten Zustand den Träger 13, d. h. den ersten Kupplungsbestandteil 30a, relativ zu dem Gehäuse 3 fest abstützt und in einem deaktivierten Zustand den Träger 13 in seiner Rotation freigibt. In anderen Worten ausgedrückt, wird erfindungsgemäß die Bremse 10 zusammen mit der Kupplung 9 in den Trockenraum 29 verlegt, da der Verbrennungsmotor 36 bzw. der Dämpfer 18 mit der Kupplung 9 und der Bremse 10 zum Gehäuse 3 verbunden ist. Des Weiteren gibt es einen zusammengebauten Träger 13, der die Nabe 43 zur inneren Getriebeeingangswelle 12, die Steckverzahnung 44 zum Dämpfer 18, die Bremsscheibe 14, den Kupplungsdeckel 15 und eine Reibfläche 17 der Kupplung 9 trägt. Die Bremse 10 ist aus einem oder mehreren Bremssätteln 11 ausgeführt. Diese beanspruchen keinen Rundum-Bauraum und können mit Lageraugen 24 und Differen- tial 41 verschachtelt werden. So wird der Axialbauraum optimal kurz. As an alternative to the design of the blocking device 10 as a frictionally acting brake, this is implemented in further versions as a positively acting blocking device 10, for example as a claw brake. However, the blocking device 10 is always designed in such a way that in an activated state it firmly supports the carrier 13, ie the first coupling component 30a, relative to the housing 3 and, in a deactivated state, releases the carrier 13 in its rotation. In other words, according to the invention, the brake 10 is relocated together with the clutch 9 into the drying room 29, since the internal combustion engine 36 or the damper 18 is connected to the housing 3 with the clutch 9 and the brake 10. Furthermore, there is an assembled carrier 13 which carries the hub 43 to the inner transmission input shaft 12, the splines 44 to the damper 18, the brake disc 14, the clutch cover 15 and a friction surface 17 of the clutch 9. The brake 10 is made up of one or more brake calipers 11. These do not take up any all-round installation space and can be nested with bearing eyes 24 and differential 41. This way, the axial installation space is optimally short.
