Die Erfindung betrifft ein Hybridgetriebe für einen Kraftfahrzeugantriebsstrang, mit einem einen Nassraum bildenden Gehäuse, einer elektrischen Maschine, einer zu zumindest einem Teil in dem Nassraum angeordneten und mit einem Rotor der elektrischen Maschine gekoppelten Getriebeeinrichtung, einer außerhalb des Nassraums angeordneten Kupplung sowie einer ebenfalls außerhalb des Nassraums angeordneten, mit einem Bestandteil der Kupplung oder der Getriebeeinrichtung in Eingriff bringbaren 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 at least in part in the wet area and coupled to a rotor of the electric machine, a clutch arranged outside the wet area and a clutch also located outside the Wet room arranged, with a component of the clutch or the transmission device can be brought into engagement 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 bekannt, Kupplungen oder Bremsen in einen Trockenraum zu verlegen, um die im Betrieb 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 prior art transmissions, it is already known in principle to relocate clutches or brakes in a dry room in order to reduce the drag losses that occur during operation. An example of this is the DE 10 2017 124 074 A1 to call. Another state of the art is with the US 2019/0275878 A1 as well as the WO 2019/141561 A1 known.

Ein Nachteil der aus dem Stand der Technik bekannten Getriebesysteme besteht jedoch darin, dass diese eine relativ große axiale Länge aufweisen. Dadurch ist die Einsetzbarkeit deutlich beschränkt.A disadvantage of the transmission systems known from the prior art, however, is that they have a relatively large axial length. As a result, the usability is clearly limited.

Es ist damit Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik bekannten Nachteile zu beheben und insbesondere ein axial kurzbauendes Hybridgetriebe mit möglichst geringen Schleppverlusten zur Verfügung zu stellen.It is therefore the object of the present invention to eliminate the disadvantages known from the prior art and, in particular, to provide an axially short hybrid transmission 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.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.

Weitergehende vorteilhafte Ausführungen sind mit den Unteransprüchen beansprucht und nachfolgend näher erläutert.Further advantageous designs 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 Betrieb nur geringfügig im Schlupfmodus betrieben werden und fast ausschließlich eine Haltefunktion umsetzen braucht, kann die Blockiereinrichtung besonders kompakt umgesetzt 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 Halteteil (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 verteilt angeordnet sind, sodass die Bremskraft / Haltekraft der Blockiereinrichtung möglichst gleichmäßig am Umfang verteilt ist.Furthermore, it is expedient if several holding parts are arranged distributed in the circumferential direction, so that the braking force / holding force of the blocking device is distributed as evenly as possible over the circumference.

Ist das zumindest eine Halteteil radial außerhalb sowie axial auf gleicher Höhe mit zumindest einem Abschnitt, vorzugsweise einem Reibelement, einem Gegendruckplattenbereich, einer Anpressplatte und / oder einer Tellerfeder der Kupplung angeordnet, werden Blockiereinrichtung und Kupplung möglichst geschickt axial ineinander verschachtelt.If the at least one holding part is arranged radially outside and axially at the same height as at least one section, preferably a friction element, a counter-pressure plate area, a pressure plate and / or a plate spring of the clutch, the blocking device and clutch are axially nested in one another as cleverly as possible.

Die Kupplung ist bevorzugt zwischen zumindest zwei Bestandteilen der Getriebeeinrichtung wirkend eingesetzt.The clutch is preferably used to act between at least two components of the transmission device.

Des Weiteren ist es zweckmäßig, wenn ein mit einer Getriebewelle verbundener Träger vorhanden ist, der unmittelbar einen (mit dem zumindest einen Halteteil zusammenwirkenden) Abstützbereich der Blockiereinrichtung, der vorzugsweise als eine Bremsscheibe ausgebildet ist, aufweist.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) and which is preferably designed as a brake disk.

Demnach ist es auch zweckmäßig, wenn der Träger unmittelbar einen Kupplungsdeckel der Kupplung aufnimmt und / oder eine mit einer Kupplungsscheibe der Kupplung zusammenwirkende Reibfläche aufweist. Dadurch wird der Aufbau weiter vereinfacht.Accordingly, it is also expedient if the carrier directly receives a clutch cover of the clutch and / or has a friction surface that interacts with a clutch disc of the clutch. This further simplifies the structure.

Des Weiteren ist es vorteilhaft, wenn ein Schwingungsdämpfer an dem Träger befestigt ist. Bevorzugt ist dieser (bspw. als Zweimassenschwungrad ausgebildete) Schwingungsdämpfer zwischen einem mit einer Verbrennungskraftmaschine weiter verbindbaren 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 (permanent) 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. At the same time, the ring gear is preferably (permanently) non-rotatably connected to the rotor of the electrical machine.

Auch ist es zweckmäßig, wenn ein Kupplungsgehäuse der Kupplung mit einem Sonnenrad der Planetengetriebestufe drehfest verbunden ist.It is also useful if a clutch housing of the clutch is connected in a rotationally fixed manner to a sun gear 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 beschriebenen Ausführungen.In addition, the invention relates to a drive train for a hybrid-powered motor vehicle, with an internal combustion engine and one with the internal combustion engine on the input side and with at least one on the output side Output shaft coupled hybrid transmission according to the invention according to at least one of the embodiments described above.

Mit anderen Worten ausgedrückt, ist somit erfindungsgemäß eine kurzbauende Brems-Kupplungs-Kombination in einem Trockenraum zur Senkung der Schleppverluste umgesetzt. Es wird bevorzugt vorgeschlagen, eine entsprechende Bremse (Blockiereinrichtung) vorzusehen, die eine möglichst kurze axiale Ausdehnung hat. Erreicht wird das, indem die Bremse aus einem oder mehreren Bremssätteln ausgeführt ist. Diese beanspruchen keinen rundum verlaufenden Bauraum und können mit Lageraugen 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 drag 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 achieved in that 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 bearing eyes and the differential.

Die Erfindung wird nun nachfolgend anhand von Figuren näher erläutert.The invention will now be explained in more detail below with reference to figures.

Es zeigen:

  • 2 a schematic view of a drive train with the after 1 trained hybrid transmission.

Die Figuren sind lediglich schematischer Natur und dienen ausschließlich dem Verständnis der Erfindung. Die gleichen Elemente sind mit denselben Bezugszeichen versehen.The figures are merely of a schematic nature and are used exclusively for understanding the invention. The same elements are provided with the same reference symbols.

Die 2 lässt zunächst einen bevorzugten Einsatzbereich eines erfindungsgemäßen Hybridgetriebes 1 erkennen. Das Hybridgetriebe 1 ist bevorzugt in einem Antriebsstrang 40 eines Kraftfahrzeuges eingesetzt. Eine Verbrennungskraftmaschine 36 ist mit einem Eingang 37 des Hybridgetriebes 1 verbunden. Ein Ausgang 38 des Hybridgetriebes 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.the 2 initially leaves a preferred area of application of a hybrid transmission according to the invention 1 recognize. The hybrid transmission 1 is preferred in a powertrain 40 of a motor vehicle used. An internal combustion engine 36 is with an entrance 37 of the hybrid transmission 1 tied together. An exit 38 of the hybrid transmission 1 is about a differential 41 with two output shafts 39a , 39b connected to an axle of the motor vehicle. The hybrid transmission 1 are an electrical machine 4th and a transmission device 6th assigned directly.

Mit 1 ist der nähere Aufbau des Hybridgetriebes 1 veranschaulicht. Das Hybridgetriebe 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 1 is the closer structure of the hybrid transmission 1 illustrated. The hybrid transmission 1 therefore has a housing 3 on that a wet room 2 encloses. Under a wet room 2 is a space that is at least partially filled with oil or through which oil flows during operation. Inside the case 3 / of the wet room 2 is an electrical machine 4th arranged.

Die elektrische Maschine 4 weist auf typische Weise einen fest im Gehäuse 3 aufgenommenen 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.The electric machine 4th typically has a stuck in the case 3 recorded stator 23 and one relative to the stator 23 rotatably arranged rotor 5 on. The rotor 5 stands with a gear mechanism 6th in causal context. The transmission device 6th has a planetary gear stage 20th on.

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 Ausführung ist der Planetenträger 26 weiter mit einer in 1 ebenfalls teilweise zu erkennenden Zwischenwelle 27 der Getriebeeinrichtung 6 gekoppelt.In this version is the rotor 5 with a ring gear 19th the planetary gear stage 20th permanently non-rotatably connected. A sun gear 22nd the planetary gear stage 20th directly forms a gear shaft 12th that acts as the transmission input shaft. Several planet gears distributed in the circumferential direction 25th are on a planet carrier 26th the planetary gear stage 20th rotatably recorded. The planet carrier is in this version 26th continue with an in 1 also partially recognizable intermediate shaft 27 the gear mechanism 6th coupled.

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 Umgebung hin geöffnet und teilweise von dem Gehäuse 3 mit umschlossen. Die Getriebewelle 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 12th penetrates an opening 28 in the case 3 and protrudes from the wet room 2 to the outside of the housing 3 out and into a drying room 29 into it. The drying room 29 is typically at least partially open to the environment and partially from the housing 3 with enclosed. The gear shaft 12th thus with one component, in particular with her with the planetary gears 25th toothed component within the wet room 2 arranged and with another component outside the wet room 2 , ie inside the drying room 29 arranged.

In dem Trockenraum 29 sind eine Kupplung 9 sowie eine Blockiereinrichtung 10 angeordnet. Die Kupplung 9 und die Blockiereinrichtung 10 dienen auf typische Weise zum Schalten der Getriebeeinrichtung 6 zwischen zumindest zwei unterschiedlichen Betriebsmodi. In diesem Zusammenhang sei der Vollständigkeit halber auch darauf hingewiesen, 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 Drehachse 35 und unter Umfangsrichtung eine Richtung entlang einer koaxial zur Drehachse 35 verlaufenden Kreislinie zu verstehen.In the drying room 29 are a clutch 9 and a blocking device 10 arranged. The coupling 9 and the blocking device 10 are typically used to shift the gear mechanism 6th 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 axial / axial direction, radial / radial direction and circumferential direction in relation to the axis of rotation 35 are to be set. Axial / axial direction is therefore a direction along the axis of rotation 35 , under radial / radial direction a direction perpendicular to the axis of rotation 35 and under the circumferential direction, a direction along a coaxial with the axis of rotation 35 to understand running circular line.

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 drehfest verbunden, während sie in einer geöffneten Stellung der Kupplung 9 frei relativ zueinander verdrehbar sind.The coupling 9 is on the part of its first coupling component 30a with a first transmission component 7th in the form of the gear shaft 12th non-rotatably connected. A second coupling component 30b the clutch 9 is with a second gear component 8th in the form of the ring gear 19th non-rotatably connected. Thus the clutch 9 between the gear shaft 12th and the ring gear 19th used effectively. In a closed position of the clutch 9 are gear shaft 12th and ring gear 19th connected to one another in a rotationally fixed manner while they are in an open position of the clutch 9 are freely rotatable relative to each other.

Die Kupplung 9 ist in dieser Ausführung als Reibkupplung, nämlich als eine Einscheibenkupplung, realisiert. Die Kupplung 9 weist ein Kupplungsgehäuse 21 auf, das eine Anpressplatte 31 axial verschiebbar, jedoch drehfest, aufnimmt. Das Kupplungsgehäuse 21 weist einen Kupplungsdeckel 15 auf, der eine Tellerfeder 32 schwenkbar lagert. Kupplungsgehäuse 21 und Anpressplatte 31 sind folglich Teil eines ersten Kupplungsbestandteils 30a. Axial zwischen der Anpressplatte 31 und einem Gegendruckplattenbereich 33 des Kupplungsgehäuses 21, welcher Gegendruckplattenbereich 33 zugleich eine Reibfläche 17 unmittelbar ausbildet, ist die Kupplungsscheibe 16 eingesetzt. Die Kupplungsscheibe 16 ist direkt mit dem Hohlrad 19 verbunden. Die Kupplungsscheibe 16 bildet einen Teil eines zweiten Kupplungsbestandteils 30b.The coupling 9 is realized in this embodiment as a friction clutch, namely as a single-disc clutch. The coupling 9 has a clutch housing 21 on that a pressure plate 31 axially displaceable, but non-rotatably, receives. The clutch housing 21 has a clutch cover 15th on, of a disc spring 32 pivotable. Clutch housing 21 and pressure plate 31 are therefore part of a first coupling component 30a . Axially between the pressure plate 31 and a platen area 33 of the clutch housing 21 which counter pressure plate area 33 at the same time a friction surface 17th forms directly, is the clutch disc 16 used. The clutch disc 16 is right with the ring gear 19th tied together. The clutch disc 16 forms part of a second coupling 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 Träger 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 diesem Zwecke eine Steckverzahnung 44 auf. Der Schwingungsdämpfer 18 ist auf typische Weise im Betrieb eingangsseitig mit einer Ausgangswelle 34 der Verbrennungskraftmaschine 36 weiter verbunden. Ausgangsseitig ist der Schwingungsdämpfer 18 direkt an den Träger 13 angebunden.The first coupling component 30a also has a carrier 13th on. This carrier 13th forms an integral part of the clutch housing 21 , especially the counter pressure plate area 33 with the friction surface 17th , the end. At the same time, the wearer takes 13th the clutch cover 15th on. The clutch cover 15th is on the carrier 13th attached. The moreover one is the carrier 13th with a vibration damper 18th , here in the form of a dual mass flywheel, further connected. The carrier 13th has a spline 44 for this purpose. The vibration damper 18th is typically in operation on the input side with an output shaft 34 the internal combustion engine 36 further connected. The vibration damper is on the output side 18th directly to the wearer 13th tied up.

Dadurch, dass der Träger 13 (über eine Nabe 43) mit der Getriebewelle 12 direkt verbunden ist, ist die Verbrennungskraftmaschine 36 im Betrieb permanent mit der Getriebewelle 12 drehfest gekoppelt.By being the carrier 13th (via a hub 43) with the gear shaft 12th is directly connected, is the internal combustion engine 36 permanently with the gear shaft during operation 12th non-rotatably coupled.

Erfindungsgemäß ist die Blockiereinrichtung 10 so relativ zu der Kupplung 9 angeordnet, dass sie diese in axialer Richtung überragt / in axialer Richtung überlappend mit dieser angeordnet ist.The blocking device is according to the invention 10 so relative to the clutch 9 arranged that it projects beyond this in the axial direction / is arranged to overlap with this 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 Blockiereinrichtung 10 in dieser Ausführung als Bremse realisiert ist, ist der Abstützbereich 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 version is part of the blocking device 10 through the first coupling component 30a , namely the carrier 13th , trained with. The carrier 13th has a disk-shaped support area for this purpose 14th on. As the blocking device 10 is implemented as a brake in this version, is the support area 14th also known as a brake disc. The support area 14th stands in the radial direction outwards over the pressure plate 31 and the counter pressure plate area 33 out.

Der Abstützbereich 14 befindet sich in Wirkzusammenhang mit mehreren in Umfangsrichtung 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 14th is in operative connection with several holding parts distributed in the circumferential direction 11 the blocking device 10 . 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 extend 11 preferably by less than 30 ° in the circumferential direction about a central axis of rotation 35 the gear shaft 12th .

Wie bspw. in 1 zu einer Unterseite erkennbar, ist das jeweilige Halteteil 11 axial zwischen dem Gehäuse 3 und dem Schwingungsdämpfer 18 untergebracht. Insbesondere befindet sich das Halteteil 11 in axialer Richtung auf Höhe mit dem Kupplungsdeckel 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.Such as in 1 The respective holding part can be seen on a lower side 11 axially between the housing 3 and the vibration damper 18th housed. In particular, there is the holding part 11 in the axial direction level with the clutch cover 15th , the disc spring 32 as well as the pressure plate 31 . The holding part is also located 11 axially next to in one through the housing 3 with trained to support the rotor 5 used bearing eye area 24 . The holding part is also located 11 in relation to the axis of rotation 35 radially offset from the differential 41 .

Alternativ zu der Ausbildung der Blockiereinrichtung 10 als reibkraftschlüssig wirkende Bremse, ist diese in weiteren Ausführungen als formschlüssig wirkende Blockiereinrichtung 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.As an alternative to the design of the blocking device 10 As a frictionally acting brake, this is in further versions as a form-locking acting blocking device 10 , implemented as a claw brake, for example. The blocking device 10 however, it is always designed in such a way that it supports the carrier in an activated state 13th , ie the first coupling component 30a , relative to the housing 3 firmly supported and in a deactivated state the carrier 13th releases in its rotation.

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 Differential 41 verschachtelt werden. So wird der Axialbauraum optimal kurz.In other words, according to the invention, the brake 10 together with the clutch 9 in the drying room 29 relocated as the internal combustion engine 36 or the damper 18th with the clutch 9 and the brake 10 to the housing 3 connected is. There is also an assembled carrier 13th that connects the hub 43 to the inner transmission input shaft 12th , the spline 44 to the damper 18th who have favourited the brake disc 14th , the clutch cover 15th and a friction surface 17th the clutch 9 wearing. The brake 10 is made up of one or more calipers 11 executed. These do not take up any all-round installation space and can be fitted with bearing eyes 24 and differential 41 be nested. This way, the axial installation space is optimally short.
