Definitions

  • the invention relates to a transmission arrangement for a transmission of a vehicle or the like, comprising a separating housing element which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, at least one separation device for separating the torque flow of one Drive from a transmission input shaft of the transmission and a Tilger discomfort.
  • the invention further relates to a transmission arrangement for a transmission of a vehicle or the like, comprising a separating housing element, which is designed to subdivide the gear assembly into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, and at least one separating device for separating the Torque flow of a drive from a transmission input shaft of the transmission.
  • Gear parts such as a motor vehicle must be acted upon with lubricant, on the one hand to keep friction losses as low as possible, on the other hand, to allow cooling of the gear parts.
  • known gear arrangements include, for example, a torsion damper for damping torsional vibrations and a separating clutch and possibly a damper.
  • a disadvantage of known gear arrangements is that on the one hand a sufficient rotational nonuniformity decoupling is not guaranteed or this can be arranged only at the cost considerable additional space.
  • Another disadvantage is that they are essentially "island solutions”, so represent special cases that are not readily transferable to other transmissions. It is therefore an object of the present invention to provide a gear arrangement which ensures rotational nonuniformity decoupling while at the same time being spatially neutral and, moreover, has increased flexibility in terms of adaptation to different boundary conditions.
  • the present invention solves the problem with a transmission arrangement for a transmission comprising a separating housing element which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, at least one separating device for separating the torque flow of one Drive from a transmission input shaft of the transmission, and a Tilger wisdom, wherein the Tilger dressed is arranged in the torque flow between the secondary side of the at least one torsional damper and the primary side of the separator, characterized in that at least one torsion damper is disposed in the drying room, and at least one separator in the wet room is arranged, and wherein a connection device for an electrical machine is arranged, which on its radially inner side with a radial outer side of at least one of the devices in operative connection is, in particular in the same axial plane as the at least one device is arranged.
  • the present invention also achieves the object with a transmission arrangement for a transmission, comprising: a separating housing element, which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, and at least one separation device for separation the torque flow of a drive from a transmission input shaft of the transmission, characterized in that at least one torsion damper is arranged in the drying room, and at least one separating device is arranged in the wet room, and that a connection device for an electric machine in the wet room is arranged, wherein the connecting device extends in the radial direction and is arranged in the axial direction next to the separating device, in particular on the secondary side of the separating device.
  • a separating housing element which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, and at least one separation device for separation the torque flow of a drive
  • the absorber device is arranged in a drying room. This allows for a simple maintenance, on the other hand, a direct power transmission is made possible by the torsion damper on the absorber.
  • the absorber device for damping vibrations at least first, in particular first and second order is formed. This allows for improved vibration damping.
  • vibrations by a cylinder deactivation for example, two of four cylinders, are taken into account.
  • the absorber device is connected on one side to the separating device. This allows a reliable and at the same time simple, inexpensive fixing of the absorber device to the separator.
  • the torsion damper in the torque flow on its secondary side on a soft soft connecting element.
  • a wobble-soft connecting element component loads can be reduced, which increases their service life.
  • the torsion damper has an additional mass element in the torque flow on its secondary side.
  • an additional inertia is provided which minimizes, for example, gear teeth of gears or the like or avoids and increases the decoupling quality of the torsion damper as required.
  • a radial offset between a drive shaft, which is connected to the primary side of the torsion damper, and an input element of the separator compensated. This can be dispensed with an expensive, costly compensation of a radial offset between the drive shaft and input element of the separator by means of other transmission parts.
  • connection device is connected to the secondary side of the separation device. This allows a substantially direct connection of the electric machine to the transmission input shaft.
  • the separating device is designed in the form of a coupling. This can be provided in a reliable and cost-effective manner, a separator.
  • the secondary side of the coupling is formed by an outer disk carrier and the primary side by an inner disk carrier. This makes it possible to couple the connection device with the coupling in a particularly simple manner.
  • a primary side element of the separating device and the absorber device are mounted in the separating housing element, in particular in the form of a bearing plate, in particular via a deep groove ball bearing. This provides a compact axial bearing.
  • the separating housing element is arranged such that the wet space forms an interior of the transmission.
  • a dry space or wet space for the gear assembly is provided in a simple manner.
  • the absorber device is arranged substantially in the radial direction within the maximum radial extent of the torsion damper, in particular substantially in the same axial plane. This achieves a particularly compact axial installation space.
  • the torsion damper in the torque flow on its secondary side on a soft-soft connecting element. By means of a dew-soft connecting element component loads can be reduced, which increases their service life.
  • connection device is designed in the form of a spur drive, in particular wherein at least one axis of rotation of the spur drive is arranged in the radial direction within the maximum radial extent of the separation device. This makes it easy to arrange the connection device in the axial direction next to the separating device.
  • an input element of the separating device is mounted by means of a pilot bearing in a shaft which is connected to the primary side of the torsion damper.
  • the input hub of the separator is possible.
  • a radial offset compensation by the torsion damper is no longer necessary.
  • the separating housing element is expediently mounted by means of a) a running sleeve and at least one sealing element or b) a race and a thrust bearing. This can be dispensed with a radial bearing, for example in the bearing plate.
  • the separating device comprises at least one actuating element, wherein a sealing element and / or a running surface of the actuating element are fixed to the primary side of the separating device, preferably by means of laser welding.
  • a sealing element and / or a running surface of the actuating element are fixed to the primary side of the separating device, preferably by means of laser welding.
  • piston seals and / or piston running surfaces can be fastened to an outer disk carrier of a clutch and its actuating piston in a simple manner.
  • the secondary side of the separator is connected via a rivet connection with a hub, on the radial inner and outer sides of each a spline for connection to other elements, in particular to a Transmission input shaft is arranged.
  • the inner disk carrier of a clutch can be connected via a Nietval with a hub part and be connected in a simple manner with other elements, such as a transmission input shaft.

Description

Getriebeanordnung für ein Getriebe eines Fahrzeugs oder dergleichen  Gear arrangement for a transmission of a vehicle or the like
Die Erfindung betrifft eine Getriebeanordnung für ein Getriebe eines Fahrzeugs oder dergleichen, umfassend ein Trenngehäuseelement, welches ausgebildet ist, die Getriebeanordnung in zumindest einen Nassraum und zumindest einen Trockenraum zu unterteilen, zumindest einen Torsionsdämpfer zur Dämpfung von Torsionsschwingungen, zumindest eine Trenneinrichtung zur Trennung des Drehmomentflusses eines Antriebs von einer Getriebeeingangswelle des Getriebes und eine Tilgereinrichtung. The invention relates to a transmission arrangement for a transmission of a vehicle or the like, comprising a separating housing element which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, at least one separation device for separating the torque flow of one Drive from a transmission input shaft of the transmission and a Tilgereinrichtung.
Die Erfindung betrifft weiter eine Getriebeanordnung für ein Getriebe eines Fahrzeugs oder dergleichen, umfassend ein Trenngehäuseelement, welches ausgebildet ist, die Getriebeanordnung in zumindest einen Nassraum und zumindest einen Trockenraum zu unterteilen, zumindest einen Torsionsdämpfer zur Dämpfung von Torsionsschwingungen, und zumindest eine Trenneinrichtung zur Trennung des Drehmomentflusses eines Antriebs von einer Getriebeeingangswelle des Getriebes. The invention further relates to a transmission arrangement for a transmission of a vehicle or the like, comprising a separating housing element, which is designed to subdivide the gear assembly into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, and at least one separating device for separating the Torque flow of a drive from a transmission input shaft of the transmission.
Getriebeteile, beispielsweise eines Kraftfahrzeugs müssen mit Schmiermittel beaufschlagt werden, einerseits um Reibungsverluste möglichst gering zu halten, andererseits auch um eine Kühlung der Getriebeteile zu ermöglichen. Darüber hinaus umfassen bekannte Getriebeanordnungen beispielsweise einen Torsionsdämpfer zur Dämpfung von Torsionsschwingungen sowie eine Trennkupplung und gegebenenfalls einen Tilger. Durch die immer größere Anzahl von Hybridfahrzeugen muss auf beengtem, maximalem Bauraum somit nicht nur die Bereitstellung von Schmiermitteln und eine Dämpfung von Schwingung erfolgen, sondern auch eine elektrische Maschine an das Getriebe angebunden werden. Gear parts, such as a motor vehicle must be acted upon with lubricant, on the one hand to keep friction losses as low as possible, on the other hand, to allow cooling of the gear parts. In addition, known gear arrangements include, for example, a torsion damper for damping torsional vibrations and a separating clutch and possibly a damper. As a result of the ever increasing number of hybrid vehicles, it is not only necessary to provide lubricants and dampen vibration in a cramped, maximum installation space, but also to connect an electrical machine to the transmission.
Nachteilig bei bekannten Getriebeanordnungen ist dabei, dass zum einen eine ausreichende Drehungleichförmigkeitsentkopplung nicht gewährleistet ist oder diese nur unter Inkaufnahme erheblichen zusätzlichen Bauraums überhaupt angeordnet werden können. Ein weiterer Nachteil ist, dass diese im Wesentlichen„Insellösungen" sind, also Spezialfälle darstellen, die nicht ohne Weiteres auf andere Getriebe übertragbar sind. Eine Aufgabe der vorliegenden Erfindung ist es daher, eine Getriebeanordnung zur Verfügung zu stellen, welche eine Drehungleichförmigkeitsentkopplung gewährleistet, gleichzeitig bau räum neutral ist und darüber hinaus eine erhöhte Flexibilität hinsichtlich der Anpassung an verschiedenen Randbedingungen aufweist. A disadvantage of known gear arrangements is that on the one hand a sufficient rotational nonuniformity decoupling is not guaranteed or this can be arranged only at the cost considerable additional space. Another disadvantage is that they are essentially "island solutions", so represent special cases that are not readily transferable to other transmissions. It is therefore an object of the present invention to provide a gear arrangement which ensures rotational nonuniformity decoupling while at the same time being spatially neutral and, moreover, has increased flexibility in terms of adaptation to different boundary conditions.
Die vorliegende Erfindung löst die Aufgabe bei einer Getriebeanordnung für ein Getriebe, umfassend ein Trenngehäuseelement, welches ausgebildet ist, die Getriebeanordnung in zumindest einen Nassraum und zumindest einen Trockenraum zu unterteilen, zumindest einen Torsionsdämpfer zur Dämpfung von Torsionsschwingungen, zumindest eine Trenneinrichtung zur Trennung des Drehmomentflusses eines Antriebs von einer Getriebeeingangswelle des Getriebes, und eine Tilgereinrichtung, wobei die Tilgereinrichtung im Drehmomentfluss zwischen der Sekundärseite des zumindest einen Torsionsdämpfers und der Primärseite der Trenneinrichtung angeordnet ist, dadurch, dass zumindest ein Torsionsdämpfer in dem Trockenraum angeordnet ist, und zumindest eine Trenneinrichtung in dem Nassraum angeordnet ist, und wobei eine Anbindungseinrichtung für eine elektrische Maschine angeordnet ist, die auf ihrer radialen Innenseite mit einer radialen Außenseite zumindest einer der Einrichtungen in Wirkverbindung steht, insbesondere in der gleichen axialen Ebene wie die zumindest eine Einrichtung angeordnet ist. The present invention solves the problem with a transmission arrangement for a transmission comprising a separating housing element which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, at least one separating device for separating the torque flow of one Drive from a transmission input shaft of the transmission, and a Tilgereinrichtung, wherein the Tilgereinrichtung is arranged in the torque flow between the secondary side of the at least one torsional damper and the primary side of the separator, characterized in that at least one torsion damper is disposed in the drying room, and at least one separator in the wet room is arranged, and wherein a connection device for an electrical machine is arranged, which on its radially inner side with a radial outer side of at least one of the devices in operative connection is, in particular in the same axial plane as the at least one device is arranged.
Die vorliegende Erfindung löst die Aufgabe ebenfalls bei einer Getriebeanordnung für ein Getriebe, umfassend: ein Trenngehäuseelement, welches ausgebildet ist, die Getriebeanordnung in zumindest einen Nassraum und zumindest einen Trockenraum zu unterteilen, zumindest einen Torsionsdämpfer zur Dämpfung von Torsionsschwingungen, und zumindest eine Trenneinrichtung zur Trennung des Drehmomentflusses eines Antriebs von einer Getriebeeingangswelle des Getriebes, dadurch, dass zumindest ein Torsionsdämpfer in dem Trockenraum angeordnet ist, und zumindest eine Trenneinrichtung in dem Nassraum angeordnet ist, und dass eine Anbindungseinrichtung für eine elektrische Maschine in dem Nassraum angeordnet ist, wobei die Anbindungseinrichtung sich in radialer Richtung erstreckt und in axialer Richtung neben der Trenneinrichtung angeordnet ist, insbesondere auf der Sekundärseite der Trenneinrichtung. Einer der damit erzielten Vorteile ist, dass eine ausreichende Drehungleichförmig- keitsentkopplung gewährleistet ist. Ein weiterer Vorteil ist, dass ein kompakter axialer Bauraum ermöglicht wird. Darüber hinaus wird Flexibilität erhöht, sodass die Getriebeanordnung an verschiedenste Randbedingungen anpassbar ist. The present invention also achieves the object with a transmission arrangement for a transmission, comprising: a separating housing element, which is designed to subdivide the gear arrangement into at least one wet space and at least one drying space, at least one torsion damper for damping torsional vibrations, and at least one separation device for separation the torque flow of a drive from a transmission input shaft of the transmission, characterized in that at least one torsion damper is arranged in the drying room, and at least one separating device is arranged in the wet room, and that a connection device for an electric machine in the wet room is arranged, wherein the connecting device extends in the radial direction and is arranged in the axial direction next to the separating device, in particular on the secondary side of the separating device. One of the advantages achieved with this is that sufficient rotational uniformity decoupling is ensured. Another advantage is that a compact axial space is made possible. In addition, flexibility is increased, so that the gear arrangement is adaptable to a variety of boundary conditions.
Weitere Merkmale, Vorteile und bevorzugte Ausführungsformen der Erfindung sind im Folgenden beschrieben oder werden dadurch offenbar: Further features, advantages and preferred embodiments of the invention are described below or become apparent:
Vorteilhafterweise ist die Tilgereinrichtung in einem Trockenraum angeordnet. Dies ermöglicht zum einen eine einfache Wartung, zum anderen wird eine direkte Kraftübertragung von dem Torsionsdämpfer auf die Tilgereinrichtung ermöglicht. Advantageously, the absorber device is arranged in a drying room. This allows for a simple maintenance, on the other hand, a direct power transmission is made possible by the torsion damper on the absorber.
Zweckmäßigerweise ist die Tilgereinrichtung zur Dämpfung von Schwingungen zumindest erster, insbesondere erster und zweiter, Ordnung ausgebildet. Damit wird eine verbesserte Schwingungsdämpfung ermöglicht. So können beispielsweise auch Schwingungen durch eine Zylinderabschaltung, beispielsweise zwei von vier Zylindern, berücksichtigt werden. Conveniently, the absorber device for damping vibrations at least first, in particular first and second order is formed. This allows for improved vibration damping. Thus, for example, vibrations by a cylinder deactivation, for example, two of four cylinders, are taken into account.
Vorteilhafterweise ist die Tilgereinrichtung einseitig an der Trenneinrichtung angebunden. Dies ermöglicht eine zuverlässige und gleichzeitig einfache, kostengünstige Festlegung der Tilgereinrichtung an der Trenneinrichtung. Advantageously, the absorber device is connected on one side to the separating device. This allows a reliable and at the same time simple, inexpensive fixing of the absorber device to the separator.
Zweckmäßigerweise weist der Torsionsdämpfer im Drehmomentfluss auf seiner Sekundärseite ein taumelweiches Verbindungselement auf. Mittels eines taumelweichen Verbindungselement können Bauteilbelastungen reduziert werden, was deren Lebensdauer erhöht. Conveniently, the torsion damper in the torque flow on its secondary side on a soft soft connecting element. By means of a wobble-soft connecting element component loads can be reduced, which increases their service life.
Vorteilhafterweise weist der Torsionsdämpfer im Drehmomentfluss auf seiner Sekundärseite ein Zusatzmasseelement auf. Damit wird eine zusätzliche Massenträgheit zur Verfügung gestellt, welche beispielsweise Verzahnungsgeräusche von Verzahnungen minimiert oder dergleichen bzw. vermeidet und je nach Anforderung auch die Entkopplungsgüte des Torsionsdämpfers erhöht. Zweckmäßigerweise ist mittels des Torsionsdämpfers ein radialer Versatz zwischen einer Antriebswelle, welche mit der Primärseite des Torsionsdämpfers verbunden ist, und einem Eingangselement der Trenneinrichtung ausgleichbar. Damit kann auf einen aufwändigen, kostenintensiven Ausgleich eines radialen Versatzes zwischen Antriebswelle und Eingangselement der Trenneinrichtung mittels weiterer Getriebeteile verzichtet werden. Advantageously, the torsion damper has an additional mass element in the torque flow on its secondary side. Thus, an additional inertia is provided which minimizes, for example, gear teeth of gears or the like or avoids and increases the decoupling quality of the torsion damper as required. Appropriately, by means of the torsion damper, a radial offset between a drive shaft, which is connected to the primary side of the torsion damper, and an input element of the separator compensated. This can be dispensed with an expensive, costly compensation of a radial offset between the drive shaft and input element of the separator by means of other transmission parts.
Vorteilhafterweise ist die Anbindungseinrichtung mit der Sekundärseite der Trenneinrichtung verbunden. Damit ist eine im Wesentlichen direkte Anbindung der elektrischen Maschine an die Getriebeeingangswelle möglich. Advantageously, the connection device is connected to the secondary side of the separation device. This allows a substantially direct connection of the electric machine to the transmission input shaft.
Zweckmäßigerweise ist die Trenneinrichtung in Form einer Kupplung ausgebildet. Damit kann auf zuverlässige und kostengünstige Weise eine Trenneinrichtung zur Verfügung gestellt werden. Conveniently, the separating device is designed in the form of a coupling. This can be provided in a reliable and cost-effective manner, a separator.
Vorteilhafterweise ist die Sekundärseite der Kupplung durch einen Außenlamellen- träger und die Primärseite durch einen Innenlamellenträger gebildet. Damit lässt sich auf besonders einfache Weise die Anbindungseinrichtung mit der Kupplung koppeln. Advantageously, the secondary side of the coupling is formed by an outer disk carrier and the primary side by an inner disk carrier. This makes it possible to couple the connection device with the coupling in a particularly simple manner.
Zweckmäßigerweise sind ein Primärseitenelement der Trenneinrichtung und die Tilgereinrichtung in dem Trenngehäuseelement, insbesondere in Form eines Lagerschilds, gelagert, insbesondere über ein Rillenkugellager. Damit wird eine kompakte axiale Lagerung zur Verfügung gestellt. Expediently, a primary side element of the separating device and the absorber device are mounted in the separating housing element, in particular in the form of a bearing plate, in particular via a deep groove ball bearing. This provides a compact axial bearing.
Vorteilhafterweise ist das Trenngehäuseelement derart angeordnet, sodass der Nassraum einen Innenraum des Getriebes bildet. Damit wird auf einfache Weise ein Trockenraum bzw. Nassraum für die Getriebeanordnung zur Verfügung gestellt. Advantageously, the separating housing element is arranged such that the wet space forms an interior of the transmission. Thus, a dry space or wet space for the gear assembly is provided in a simple manner.
Zweckmäßigerweise ist die Tilgereinrichtung im Wesentlichen in radialer Richtung innerhalb der maximalen radialen Erstreckung des Torsionsdämpfers angeordnet, insbesondere im Wesentlichen in der gleichen axialen Ebene. Damit wird ein besonders kompakter axialer Bauraum erreicht. Vorteilhafterweise weist bei einer Getriebeanordnung gemäß Anspruch 14 der Torsionsdämpfer im Drehmomentfluss auf seiner Sekundärseite ein taumelweiches Verbindungselement auf. Mittels eines taumelweichen Verbindungselements können Bauteilbelastungen reduziert werden, was deren Lebensdauer erhöht. Advantageously, the absorber device is arranged substantially in the radial direction within the maximum radial extent of the torsion damper, in particular substantially in the same axial plane. This achieves a particularly compact axial installation space. Advantageously, in a transmission arrangement according to claim 14, the torsion damper in the torque flow on its secondary side on a soft-soft connecting element. By means of a dew-soft connecting element component loads can be reduced, which increases their service life.
Zweckmäßigerweise ist die Anbindungseinrichtung in Form eines Stirntriebs ausgebildet, insbesondere wobei zumindest eine Drehachse des Stirntriebs in radialer Richtung innerhalb der maximalen radialen Erstreckung der Trenneinrichtung angeordnet ist. Damit lässt sich auf einfache Weise die Anbindungseinrichtung in axialer Richtung neben der Trenneinrichtung anordnen. Conveniently, the connection device is designed in the form of a spur drive, in particular wherein at least one axis of rotation of the spur drive is arranged in the radial direction within the maximum radial extent of the separation device. This makes it easy to arrange the connection device in the axial direction next to the separating device.
Vorteilhafterweise ist ein Eingangselement der Trenneinrichtung mittels eines Pilotlagers in einer Welle, die mit der Primärseite des Torsionsdämpfers verbunden ist, gelagert. Damit ist eine einfache Lagerung beispielsweise der Eingangsnabe der Trenneinrichtung möglich. Ein radialer Versatzausgleich durch den Torsionsdämpfer ist nicht mehr notwendig. Advantageously, an input element of the separating device is mounted by means of a pilot bearing in a shaft which is connected to the primary side of the torsion damper. For a simple storage, for example, the input hub of the separator is possible. A radial offset compensation by the torsion damper is no longer necessary.
Zweckmäßigerweise ist das Trenngehäuseelement mittels a) einer Laufhülse und zumindest einem Dichtelement oder b) eines Laufrings und eines Axiallagers gelagert. Damit kann auf eine radiale Lagerung beispielsweise im Lagerschild verzichtet werden. The separating housing element is expediently mounted by means of a) a running sleeve and at least one sealing element or b) a race and a thrust bearing. This can be dispensed with a radial bearing, for example in the bearing plate.
Vorteilhafterweise umfasst die Trenneinrichtung zumindest ein Betätigungselement, wobei ein Dichtelement und/oder eine Lauffläche des Betätigungselements an der Primärseite der Trenneinrichtung festgelegt sind, vorzugsweise mittels Laserschweißen. So können beispielsweise auf einfache Weise Kolbendichtungen und/oder Kol- benlaufflächen an einem Außenlamellenträger einer Kupplung und deren Betätigungskolben befestigt werden. Advantageously, the separating device comprises at least one actuating element, wherein a sealing element and / or a running surface of the actuating element are fixed to the primary side of the separating device, preferably by means of laser welding. For example, piston seals and / or piston running surfaces can be fastened to an outer disk carrier of a clutch and its actuating piston in a simple manner.
Zweckmäßigerweise ist die Sekundärseite der Trenneinrichtung über eine Nietverbindung mit einer Nabe verbunden, auf deren radialer Innen- und Außenseite jeweils eine Steckverzahnung zur Anbindung an weitere Elemente, insbesondere an eine Getriebeeingangswelle angeordnet ist. Damit kann beispielsweise der Innenlamellen- träger einer Kupplung über einen Nietverband mit einem Nabenteil verbunden werden und auf einfache Weise mit weiteren Elementen, beispielsweise einer Getriebeeingangswelle verbunden werden. Conveniently, the secondary side of the separator is connected via a rivet connection with a hub, on the radial inner and outer sides of each a spline for connection to other elements, in particular to a Transmission input shaft is arranged. Thus, for example, the inner disk carrier of a clutch can be connected via a Nietverband with a hub part and be connected in a simple manner with other elements, such as a transmission input shaft.

Figur 1 zeigt eine Getriebeanordnung gemäß einer Ausführungsform der vorliegenden Erfindung. FIG. 1 shows a gear arrangement according to an embodiment of the present invention.
In Figur 1 ist eine Getriebeanordnung 1 gezeigt. Die Getriebeanordnung 1 weist einen Lagerschild 2 auf, der die Getriebeanordnung 1 in einen Trockenraum TR, in Figur 1 auf der linken Seite, und in einen Nassraum NR, in Figur 1 auf der rechten Seite, unterteilt. Im Trockenraum TR ist ein Zweimassenschwungrad 3 angeordnet, welches mit einer Eingangsnabe einer Trennkupplung 4 verbunden ist. Die Eingangsnabe der Trennkupplung 4 ist weiter mit einem Außenlamellenträger 8 verbunden. Die Eingangsnabe der Trennkupplung 4 ist einerseits über ein Pilotlager 22 im Kurbelwellenzapfen der Kurbelwelle 13 gelagert, andererseits über ein Axiallager 15 in Form eines Axialnadellagers zusammen mit einem Laufring 14 und einem Radialwellen- dichtring im Lagerschild 2 gelagert. Die Trennkupplung 4 umfasst neben dem Außenlamellenträger 8 einen korrespondierenden Innenlamellenträger 7, der über eine Nietverbindung 17 auf seiner Sekundärseite mit einer Nabe 18 verbunden ist, welche auf der radial äußeren Seite eine Steckverzahnung 19b zu einem Zahnrad mit Laufverzahnung und im radial inneren Bereich eine weitere Steckverzahnung 19a zu einer Getriebeeingangswelle 5 aufweist. FIG. 1 shows a gear arrangement 1. The gear assembly 1 has a bearing plate 2, which divides the gear assembly 1 in a drying space TR, in Figure 1 on the left side, and in a wet room NR, in Figure 1 on the right side. In the drying space TR, a dual-mass flywheel 3 is arranged, which is connected to an input hub of a separating clutch 4. The input hub of the separating clutch 4 is further connected to an outer disk carrier 8. The input hub of the separating clutch 4 is mounted on the one hand via a pilot bearing 22 in the crankshaft journal of the crankshaft 13, on the other hand via a thrust bearing 15 in the form of an axial needle bearing together with a race 14 and a Radialwellen- sealing ring mounted in the bearing plate 2. The separating clutch 4 comprises in addition to the outer disk carrier 8 a corresponding inner disk carrier 7, which is connected via a rivet 17 on its secondary side with a hub 18 which on the radially outer side of a spline 19b to a gear with running teeth and in the radially inner region a further spline 19a to a transmission input shaft 5 has.
In axialer Richtung und drehmomentabwärts der Trennkupplung 4 ist eine Anbin- dungseinrichtung 10 in Form eines Stirntriebs angeordnet, welcher zur Anbindung einer elektrischen Maschine (hier nicht gezeigt) dient. Hierzu sind in radialer Richtung zwei Stirnräder 25a, 25b zusammenwirkend angeordnet, die über einen Niet 17 mit dem Innenlamellenträger 7 der Trennkupplung 4 zur Übertragung von Drehmomenten verbunden sind. So überträgt beispielsweise das erste Stirnrad 25a, welches im Wesentlichen in radialer Richtung auf Höhe der Federn des Zweimassenschwungrades 3 gelagert ist (Bezugszeichen 21), auf das radial weiter innen liegende Stirnrad 25b, welches eine Laufverzahnung aufweist, Drehmoment. Über die bereits genannte Steckverzahnung 19b und die zweite Steckverzahnung 19a wird das Drehmoment schließlich auf die Getriebeeingangswelle 5 übertragen. Insgesamt ist der Drehmomentfluss 20 in Figur 1 wie folgt: ausgehend von der Antriebswelle 9 in Form einer Kurbelwelle 13 wird über einen Kurbelwellenflansch 23 das Drehmoment auf die Primärseite des Zweimassenschwungrades 3 übertragen. Sekundärseitig wird das Drehmoment dann von dem Zweimassenschwungrad 3 auf den Außenlamellenträger 8 der Trennkupplung 4 und weiter auf den Innenlamellen- träger 7 bei geschlossener Trennkupplung 4 übertragen. Der Innenlamellenträger 7 als Sekundärseite der Trennkupplung 4 überträgt schließlich über eine Nietverbindung 17 das Drehmoment auf die Getriebeeingangswelle 5. Zusätzlich oder alternativ kann das Drehmoment von der elektrischen Maschine (hier nicht gezeigt) über den Stirntrieb 10, die Steckverzahnung 19b und 19a schließlich auf die Getriebeeingangswelle 5 übertragen werden. In the axial direction and downstream of the separating clutch 4, a connection device 10 in the form of a spur drive is arranged, which serves to connect an electric machine (not shown here). For this purpose, two spur gears 25a, 25b are arranged cooperatively in the radial direction, which are connected via a rivet 17 with the inner disk carrier 7 of the separating clutch 4 for the transmission of torques. Thus, for example, transmits the first spur gear 25a, which is mounted substantially in the radial direction at the level of the springs of the dual mass flywheel 3 (reference numeral 21), on the radially inner spur gear 25b, which has a running gear, torque. About the already mentioned spline 19b and the second spline 19a, the torque is finally transmitted to the transmission input shaft 5. Overall, the torque flow 20 in FIG. 1 is as follows: starting from the drive shaft 9 in the form of a crankshaft 13, the torque is transmitted to the primary side of the dual-mass flywheel 3 via a crankshaft flange 23. On the secondary side, the torque is then transmitted from the dual-mass flywheel 3 to the outer disk carrier 8 of the separating clutch 4 and further to the inner disk carrier 7 when the separating clutch 4 is closed. The inner disk carrier 7 as secondary side of the separating clutch 4 finally transmits the torque to the transmission input shaft 5 via a rivet connection 17. Additionally or alternatively, the torque from the electric machine (not shown here) can finally be transmitted to the transmission input shaft via the spur gear 10, the splines 19b and 19a 5 are transmitted.

Die Sekundärseite des Zweimassenschwungrades 3 ist mit einem Eingangselement einer Trennkupplung 4 in Wirkverbindung. Die Trennkupplung 4 umfasst einen Innenlamellenträger 7 auf deren Primärseite und einen Außenlamellenträger 8 auf der Sekundärseite.
