Definitions

  • the invention relates to a multiple clutch arrangement for arrangement between a drive unit and a transmission, the multiple clutch arrangement having at least two clutches for connecting an input of the multiple clutch arrangement with one output each.
  • the multiple clutch arrangement thus comprises two clutches with which two outputs can be connected to a single input.
  • Such a multiple clutch arrangement is used, for example, in transmissions that consist of two sub-transmissions. It is known to design the clutches as Lamellenkupplun gene and use in a double clutch transmission. It is also known to also provide a separating clutch designed as a multi-plate clutch.
  • the multiple clutch arrangement still has at least one freewheel.
  • a one-way clutch is also a clutch, which is why the multiple clutch arrangement described can also be referred to as a three-way clutch arrangement.
  • a freewheel is also referred to as overrunning clutch and is a one-way clutch. The freewheel allows a separation of the multiple clutch arrangement and / or the drive train behind it from the remaining part of the drive train. It thus acts as a disconnect clutch.
  • the freewheel can advantageously be arranged on at least one of the clutches on the input side. It should be noted here that the freewheel, even if it is a clutch in the technical sense, is addressed as a freewheel in the present invention and the others in the multiple clutch arrangement. existing couplings as couplings.
  • the clutches referred to as clutches are in principle any type of clutches, but they are not freewheels.
  • the freewheel can preferably be arranged on the input side of at least two or exactly two clutches.
  • the freewheel can be arranged on the input side of all other couplings present in the multiple clutch arrangement. This allows the freewheel to separate the drive train from one another and split it into two separate parts.
  • the clutches can be designed as dog clutches.
  • the clutches can be designed as multi-plate clutches.
  • the clutches are designed as friction clutches, mostly as wet-running multi-plate clutches. But there are also dry double clutches.
  • the speeds are to be synchronized in a different way than by frictional engagement. This can be done, for example, by means of electric motors assigned to the transmission input shafts.
  • the freewheel can preferably have at least one pawl.
  • the freewheel can have clamping rollers or clamping bodies.
  • the freewheel can have claw rings.
  • the freewheel can comprise at least one wrap spring.
  • the freewheel is operatively connected or operatively connected to an electric motor.
  • devices for connection to the electric motor must be located on the multiple clutch arrangement.
  • the freewheel can be arranged within a sprocket. Then the sprocket is a connecting part to the electric motor, with at least the chain still being arranged between the electric motor and the freewheel.
  • further translation levels can be provided.
  • the freewheel can advantageously be arranged on the transmission side and the clutches on the motor side. The freewheel is so to speak on the wrong side angeord net because it is provided as a separation point between the multiple clutch assembly and combustion engine.
  • this structure allows a particularly space-saving arrangement of the design of the multiple clutch arrangement.
  • the freewheel is arranged on a hub.
  • the sprocket is also arranged on the hub.
  • the freewheel can be found completely inside the sprocket.
  • the freewheel is advantageously mounted inwardly via a bearing.
  • the bearing can in particular be designed as a roller bearing and here as a needle bearing.
  • the freewheel can preferably be operatively connected on the input side to a housing part of the multiple clutch arrangement.
  • the multiple clutch arrangement can be bridged via the housing, so that the freewheel can be arranged on the transmission side.
  • the freewheel on the output side can be connected to an electric motor or can be operatively connected. Then the electric motor can be connected to the partial transmissions via the couplings.
  • the freewheel can preferably be arranged as described for separating the multiple clutch arrangement from an internal combustion engine.
  • the invention relates to a hybrid transmission arrangement with a multiple clutch arrangement. This is characterized in that the multiple coupling arrangement is designed as described.
  • the hybrid transmission arrangement can preferably have at least two partial transmissions.
  • the hybrid transmission arrangement can thus be designed as a hybrid double clutch transmission arrangement or as a type of hybrid double clutch transmission arrangement.
  • the Clutches can be designed as dog clutches as described, which is not the case with known double clutch transmissions.
  • the invention relates to a motor vehicle with a multiple clutch arrangement and / or a hybrid transmission arrangement.
  • the motor vehicle is characterized in that the multiple clutch arrangement is designed as described and / or the hybrid transmission arrangement is designed as described.

  • FIG. 1 shows a motor vehicle 1 with a first drive unit 2, a second drive unit 3, a double clutch transmission arrangement 4 and a differential 5.
  • the first drive unit preferably comprises an internal combustion engine.
  • the second drive unit 3 in particular in the form of an electric motor switched off, can act on the drive train either as indicated by the line 6 or the dashed line 7. Interaction with one or both transmission input shafts is referred to as a P2 arrangement and interaction with the transmission itself as a P3 arrangement.
  • a Pf and a P4 arrangement are also known. These represent the basic variants of a parallel arrangement of first drive unit 2 and second drive unit 3.
  • a clutch arrangement for a P2 arrangement is described below.
  • FIG. 2 shows a clutch arrangement 8 as part of the double clutch transmission arrangement 4.
  • the double clutch transmission arrangement 4 is hybridized, which is why torque can reach the transmission in two ways.
  • the first way leads from the first drive unit 2 via a torsion damper for damping torsional vibrations, in particular a dual mass flywheel 9, a hub 10 and at least one housing part 11 for free-running KO.

Description

Mehrfachkupplunqsanordnunq, Hvbrid-Getriebeanordnunq sowie Kraftfahrzeug Mehrfachkupplunqsanordnunq, Hvbrid transmission arrangement and motor vehicle
Die Erfindung betrifft eine Mehrfachkupplungsanordnung zur Anordnung zwischen einer Antriebseinheit und einem Getriebe, wobei die Mehrfachkupplungsanordnung wenigstens zwei Kupplungen zur Verbindung eines Eingangs der Mehrfachkupp lungsanordnung mit jeweils einem Ausgang aufweist. The invention relates to a multiple clutch arrangement for arrangement between a drive unit and a transmission, the multiple clutch arrangement having at least two clutches for connecting an input of the multiple clutch arrangement with one output each.
Die Mehrfachkupplungsanordnung umfasst also zwei Kupplungen, mit denen zwei Ausgänge mit einem einzigen Eingang verbindbar sind. Eine derartige Mehrfach kupplungsanordnung findet beispielsweise Anwendung in Getrieben, die aus zwei Teilgetrieben bestehen. Dabei ist es bekannt, die Kupplungen als Lamellenkupplun gen auszugestalten und in einem Doppelkupplungsgetriebe einzusetzen. Dabei ist es weiterhin bekannt, ebenfalls eine als Lamellenkupplung ausgeführte Trennkupplung vorzusehen. The multiple clutch arrangement thus comprises two clutches with which two outputs can be connected to a single input. Such a multiple clutch arrangement is used, for example, in transmissions that consist of two sub-transmissions. It is known to design the clutches as Lamellenkupplun gene and use in a double clutch transmission. It is also known to also provide a separating clutch designed as a multi-plate clutch.
Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, eine Mehrfachkupp lungsanordnung anzugeben, die die beschriebenen Aufgaben in Getrieben mit zu mindest zwei Teilgetrieben erfüllt, die einfach aufgebaut ist und die auch in weiteren Ausgestaltungen als bekannten Doppelkupplungsgetrieben einsetzbar ist. Based on this, it is an object of the present invention to provide a Mehrfachkupp processing arrangement that fulfills the tasks described in transmissions with at least two sub-transmissions, which is simple in design and which can also be used in other configurations as known double clutch transmissions.
Zur Lösung dieses Problems wird vorgeschlagen, dass die Mehrfachkupplungsan ordnung weiterhin wenigstens einen Freilauf aufweist. Ein Freilauf ist ebenfalls eine Kupplung, weswegen die beschriebene Mehrfachkupplungsanordnung auch als Drei fachkupplungsanordnung bezeichenbar ist. Ein Freilauf wird auch als Überholkupp lung bezeichnet und ist eine nur in einer Drehrichtung wirkende Kupplung. Der Frei lauf erlaubt eine Trennung der Mehrfachkupplungsanordnung und/oder des dahinter liegenden Antriebsstrangs vom restlichen Teil des Antriebsstrangs. Er fungiert somit als Trennkupplung. To solve this problem, it is proposed that the multiple clutch arrangement still has at least one freewheel. A one-way clutch is also a clutch, which is why the multiple clutch arrangement described can also be referred to as a three-way clutch arrangement. A freewheel is also referred to as overrunning clutch and is a one-way clutch. The freewheel allows a separation of the multiple clutch arrangement and / or the drive train behind it from the remaining part of the drive train. It thus acts as a disconnect clutch.
Dementsprechend kann der Freilauf vorteilhafterweise auf der Eingangsseite wenigs tens einer der Kupplungen angeordnet sein. Hier sei angemerkt, dass der Freilauf, auch wenn er im technischen Sinn eine Kupplung ist, in der vorliegenden Erfindung als Freilauf angesprochen wird und die weiteren in der Mehrfachkupplungsanord- nung vorhandenen Kupplungen als Kupplungen. Die als Kupplungen bezeichneten Kupplungen sind zwar grundsätzlich beliebig ausgestaltete Kupplungen, aber keine Freiläufe. Accordingly, the freewheel can advantageously be arranged on at least one of the clutches on the input side. It should be noted here that the freewheel, even if it is a clutch in the technical sense, is addressed as a freewheel in the present invention and the others in the multiple clutch arrangement. existing couplings as couplings. The clutches referred to as clutches are in principle any type of clutches, but they are not freewheels.
Vorzugsweise kann der Freilauf auf der Eingangsseite wenigstens zweier oder genau zweier Kupplungen angeordnet sein. Insbesondere kann der Freilauf auf der Ein gangsseite aller weiteren in der Mehrfachkupplungsanordnung vorhandenen Kupp lungen angeordnet sein. Dadurch kann der Freilauf den Antriebsstrang voneinander trennen und in zwei separate Teile aufteilen. The freewheel can preferably be arranged on the input side of at least two or exactly two clutches. In particular, the freewheel can be arranged on the input side of all other couplings present in the multiple clutch arrangement. This allows the freewheel to separate the drive train from one another and split it into two separate parts.
In einer ersten Ausgestaltung können die Kupplungen als Klauenkupplungen ausge staltet sein. Alternativ können die Kupplungen als Lamellenkupplungen ausgebildet sein. Bei bekannten Doppelkupplungsgetrieben sind die Kupplungen als reibschlüs sige Kupplungen ausgebildet, meist als nasslaufende Lamellenkupplungen. Es gibt aber auch trockene Doppelkupplungen. Bei einer Ausgestaltung der Kupplungen als Klauenkupplungen bzw. als formschlüssige Kupplungen ist eine Synchronisierung der Drehzahlen auf anderer Weise als durch Reibschluss herbeizuführen. Dies kann beispielswiese mittels den Getriebeeingangswellen zugeordneten Elektromotoren erfolgen. In a first embodiment, the clutches can be designed as dog clutches. Alternatively, the clutches can be designed as multi-plate clutches. In known double clutch transmissions, the clutches are designed as friction clutches, mostly as wet-running multi-plate clutches. But there are also dry double clutches. In the case of a design of the clutches as claw clutches or as form-fitting clutches, the speeds are to be synchronized in a different way than by frictional engagement. This can be done, for example, by means of electric motors assigned to the transmission input shafts.
Bevorzugt kann der Freilauf wenigstens eine Sperrklinke aufweisen. Alternativ kann der Freilauf Klemmrollen oder Klemmkörper aufweisen. Weiter alternativ kann der Freilauf Klauenringe aufweisen. Weiter alternativ kann der Freilauf wenigstens eine Schlingfeder umfassen. The freewheel can preferably have at least one pawl. Alternatively, the freewheel can have clamping rollers or clamping bodies. Alternatively, the freewheel can have claw rings. Alternatively, the freewheel can comprise at least one wrap spring.
Bevorzugt ist vorgesehen, dass der Freilauf mit einem Elektromotor wirkverbunden oder wirkverbindbar ist. Hierzu müssen sich an der Mehrfachkupplungsanordnung Vorrichtungen zur Verbindung mit dem Elektromotor befinden. Beispielsweise kann der Freilauf innerhalb eines Kettenrades angeordnet sein. Dann ist das Kettenrad ein Verbindungsteil zum Elektromotor hin, wobei zumindest die Kette noch zwischen dem Elektromotor und dem Freilauf angeordnet ist. Darüber hinaus können weitere Übersetzungsstufen vorgesehen sein. Vorteilhafterweise kann der Freilauf getriebeseitig und die Kupplungen motorseitig angeordnet sein. Der Freilauf ist dabei so zu sagen auf der falschen Seite angeord net, da er als Trennstelle zwischen Mehrfachkupplungsanordnung und Verbren nungsmotor vorgesehen ist. Dieser Aufbau erlaubt aber eine besonders platzsparen de Anordnung der Ausgestaltung der Mehrfachkupplungsanordnung. It is preferably provided that the freewheel is operatively connected or operatively connected to an electric motor. For this purpose, devices for connection to the electric motor must be located on the multiple clutch arrangement. For example, the freewheel can be arranged within a sprocket. Then the sprocket is a connecting part to the electric motor, with at least the chain still being arranged between the electric motor and the freewheel. In addition, further translation levels can be provided. The freewheel can advantageously be arranged on the transmission side and the clutches on the motor side. The freewheel is so to speak on the wrong side angeord net because it is provided as a separation point between the multiple clutch assembly and combustion engine. However, this structure allows a particularly space-saving arrangement of the design of the multiple clutch arrangement.
Weiterhin kann vorgesehen sein, dass der Freilauf auf einer Nabe angeordnet ist. Bei einer Anordnung innerhalb eines Kettenrades ist auch das Kettenrad auf der Nabe angeordnet. Dabei kann sich der Freilauf vollständig innerhalb des Kettenrades be finden. Vorteilhafterweise ist der Freilauf nach Innen über ein Lager gelagert. Das Lager kann insbesondere als Wälzlager und hier als Nadellager ausgebildet sein. It can further be provided that the freewheel is arranged on a hub. With an arrangement within a sprocket, the sprocket is also arranged on the hub. The freewheel can be found completely inside the sprocket. The freewheel is advantageously mounted inwardly via a bearing. The bearing can in particular be designed as a roller bearing and here as a needle bearing.
Bevorzugt kann der Freilauf eingangsseitig mit einem Gehäuseteil der Mehrfach kupplungsanordnung wirkverbunden sein. Über das Gehäuse kann die Mehrfach kupplungsanordnung überbrückt werden, so dass der Freilauf getriebeseitig anordenbar ist. The freewheel can preferably be operatively connected on the input side to a housing part of the multiple clutch arrangement. The multiple clutch arrangement can be bridged via the housing, so that the freewheel can be arranged on the transmission side.
Bevorzugt kann der Freilauf auf der Ausgangsseite mit einem Elektromotor wirkver bunden oder wirkverbindbar sein. Dann ist der Elektromotor über die Kupplungen mit den Teilgetrieben verbindbar. Preferably, the freewheel on the output side can be connected to an electric motor or can be operatively connected. Then the electric motor can be connected to the partial transmissions via the couplings.
Vorzugsweise kann der Freilauf wie beschrieben zur Trennung der Mehrfachkupp lungsanordnung von einem Verbrennungsmotor angeordnet sein. The freewheel can preferably be arranged as described for separating the multiple clutch arrangement from an internal combustion engine.
Daneben betrifft die Erfindung eine Hybrid-Getriebeanordnung mit einer Mehrfach kupplungsanordnung. Diese zeichnet sich dadurch aus, dass die Mehrfachkupp lungsanordnung wie beschrieben ausgebildet ist. In addition, the invention relates to a hybrid transmission arrangement with a multiple clutch arrangement. This is characterized in that the multiple coupling arrangement is designed as described.
Vorzugsweise kann die Hybrid-Getriebeanordnung wenigstens zwei Teilgetriebe aufweisen. Die Hybrid-Getriebeanordnung kann also als Hybrid- Doppelkupplungsgetriebeanordnung oder als eine Art Hybrid- Doppelkupplungsgetriebeanordnung ausgebildet sein. Beispielsweise können die Kupplungen wie beschrieben als Klauenkupplungen ausgestaltet sein, was bei be kannten Doppelkupplungsgetrieben nicht der Fall ist. The hybrid transmission arrangement can preferably have at least two partial transmissions. The hybrid transmission arrangement can thus be designed as a hybrid double clutch transmission arrangement or as a type of hybrid double clutch transmission arrangement. For example, the Clutches can be designed as dog clutches as described, which is not the case with known double clutch transmissions.
Daneben betrifft die Erfindung ein Kraftfahrzeug mit einer Mehrfachkupplungsanord nung und/oder einer Hybrid-Getriebeanordnung. Das Kraftfahrzeug zeichnet sich dadurch aus, dass die Mehrfachkupplungsanordnung wie beschrieben und/oder die Hybrid-Getriebeanordnung wie beschrieben ausgebildet ist. In addition, the invention relates to a motor vehicle with a multiple clutch arrangement and / or a hybrid transmission arrangement. The motor vehicle is characterized in that the multiple clutch arrangement is designed as described and / or the hybrid transmission arrangement is designed as described.
Weitere Vorteile, Merkmale und Einzelheiten ergeben sich aus der folgenden Be schreibung von Ausführungsbeispielen und Figuren. Dabei zeigen: Further advantages, features and details emerge from the following description of exemplary embodiments and figures. Show:

Figur 1 zeigt ein Kraftfahrzeug 1 mit einer ersten Antriebseinheit 2, einer zweiten An triebseinheit 3, einer Doppelkupplungsgetriebeanordnung 4 und einem Differential 5. Die erste Antriebseinheit umfasst vorzugsweise eine Verbrennungskraftmaschine.FIG. 1 shows a motor vehicle 1 with a first drive unit 2, a second drive unit 3, a double clutch transmission arrangement 4 and a differential 5. The first drive unit preferably comprises an internal combustion engine.
Die zweite Antriebseinheit 3, insbesondere in Form eines Elektromotors ausgeschal tet, kann dabei entweder wie durch die Linie 6 oder die gestrichelt dargestellte Linie 7 angedeutet am Antriebsstrang angreifen. Ein Zusammenwirken mit einer oder beiden Getriebeeingangswellen wird dabei als P2-Anordnung bezeichnet und ein Zusam menwirken mit dem Getriebe selbst als P3-Anordnung. Daneben sind auch eine Pf und eine P4- Anordnung bekannt. Diese stellen die grundsätzlichen Varianten einer parallelen Anordnung von erster Antriebseinheit 2 und zweiter Antriebseinheit 3 dar. Im Folgenden wird eine Kupplungsanordnung für eine P2-Anordnung beschrieben. The second drive unit 3, in particular in the form of an electric motor switched off, can act on the drive train either as indicated by the line 6 or the dashed line 7. Interaction with one or both transmission input shafts is referred to as a P2 arrangement and interaction with the transmission itself as a P3 arrangement. A Pf and a P4 arrangement are also known. These represent the basic variants of a parallel arrangement of first drive unit 2 and second drive unit 3. A clutch arrangement for a P2 arrangement is described below.
Figur 2 zeigt eine Kupplungsanordnung 8 als Teil der Doppelkupplungsgetriebean ordnung 4. Die Doppelkupplungsgetriebeanordnung 4 ist hybridisiert, weswegen Drehmoment über zwei Wege zum Getriebe gelangen kann. Der erste Weg führt von der ersten Antriebseinheit 2 über einen Torsionsdämpfer zur Dämpfung von Torsi onsschwingungen, insbesondere ein Zweimassenschwungrad 9, eine Nabe 10 und zumindest ein Gehäuseteil 11 zum Freilauf KO. Mit der Nabe 10 ist dabei Mitnehmer- blech 12 und damit das Gehäuseteil 11 drehfest verbunden. Dabei ist ein Fußteil 14 des Gehäuseteils 11 mit dem Innenteil 16 des Freilaufs KO verbunden. Radial außen um das Innenteil 16 liegt das Außenteil 18 des Freilaufs KO. FIG. 2 shows a clutch arrangement 8 as part of the double clutch transmission arrangement 4. The double clutch transmission arrangement 4 is hybridized, which is why torque can reach the transmission in two ways. The first way leads from the first drive unit 2 via a torsion damper for damping torsional vibrations, in particular a dual mass flywheel 9, a hub 10 and at least one housing part 11 for free-running KO. With the hub 10, driver sheet 12 and thus the housing part 11 rotatably connected. A foot part 14 of the housing part 11 is connected to the inner part 16 of the freewheel KO. The outer part 18 of the freewheel KO lies radially around the inner part 16.
Auf der Eingangsseite des Freilaufs KO kann, bspw. am Mitnehmerblech 12 oder am Gehäuseteil 11 ein Tilger, insbesondere ein drehzahladaptiver Tilger, befestigt sein. A damper, in particular a speed-adaptive damper, can be attached to the input side of the freewheel KO, for example on the driving plate 12 or on the housing part 11.
Das Außenteil 18 des Freilaufs KO ist mit einer Radnabe 20 drehfest oder insgesamt fest verbunden. The outer part 18 of the freewheel KO is non-rotatably or firmly connected to a wheel hub 20.
Über die Radnabe 20 und eine Ölzuführnabe 22 ist der Lamellenträger 24 in den Drehmomentfluss eingebunden. Der Lamellenträger ist dabei gleichzeitig Eingangs lamellenträger für beide Kupplungen K1 und K2, da er die Innenlamellen 24 der Kupplung K2 und die Außenlamellen 26 der Kupplung K1 antreibt. Auf der Aus gangsseite der Kupplung K2 befindet sich der Außenlamellenträger 28, der die Au ßenlamellen 30 des Lamellenpakets 32 führt. Die Innenlamellen 34 der Kupplung KO sind dagegen mit den Innenlamellenträger 36 verbunden. Der Außenlamellenträger 28 und der Innenlamellenträger 36 befinden sich auf der Ausgangsseite der Kupp lungen. The disk carrier 24 is integrated into the torque flow via the wheel hub 20 and an oil feed hub 22. The disk carrier is at the same time input disk carrier for both clutches K1 and K2, since it drives the inner disks 24 of clutch K2 and the outer disks 26 of clutch K1. On the output side of the clutch K2 is the outer plate carrier 28, which leads the outer plates 30 of the disk set 32. The inner plates 34 of the clutch KO, however, are connected to the inner plate carrier 36. The outer disk carrier 28 and the inner disk carrier 36 are on the output side of the hitch beings.
Die Ölzuführnabe 22 ist über Nadellager 38 auf der radial äußeren Getriebeein gangswelle gelagert. Diese ist mit dem Innenlamellenträger 36 über die Steckver zahnung 40 verbunden. The oil supply hub 22 is mounted on needle bearings 38 on the radially outer gear input shaft. This is connected to the inner disk carrier 36 through the toothing 40 Verver.
Das Kettenrad 20, das ebenfalls auf der äußeren Getriebeeingangswelle gelagert ist, ist über eine Kette 42 mit einem Elektromotor 3 verbindbar. Somit kann der Elektro motor 3 über die Radnabe und den Lamellenträger 24 auf beide Teilgetriebe zugrei fen bzw. diese antreiben, wobei der Verbrennungsmotor und der auf dieser Seite des Freilaufs K0 befindliche Teil des Antriebsstrangs über den Freilauf K0 vom restlichen Antriebsstrang abgekoppelt werden können. Der Freilauf K0 fungiert also als Trenn kupplung. Eine Trennung des Verbrennungsmotors und beispielsweise des Zwei- massenschwungrades 9 vom restlichen Antriebsstrang erfolgt dabei dann, wenn über den Elektromotor 3 eine höhere Drehzahl erreicht wird als über den Verbrennungs- motor. Somit kann über die Drehzahlen des Verbrennungsmotors und des Elektro motors gesteuert werden, ob beide Antriebseinheit oder nur eine zum Antreiben des Antriebsstrangs verwendet wird. The sprocket 20, which is also mounted on the outer transmission input shaft, can be connected to an electric motor 3 via a chain 42. Thus, the electric motor 3 on the wheel hub and the disk carrier 24 on both partial transmissions or drive them, the internal combustion engine and the part of the drive train located on this side of the freewheel K0 can be uncoupled from the rest of the drive train via the freewheel K0. The freewheel K0 thus acts as a clutch. The internal combustion engine and, for example, the dual-mass flywheel 9 are separated from the rest of the drive train when a higher speed is reached via the electric motor 3 than via the internal combustion engine. engine. It can thus be controlled via the speeds of the internal combustion engine and the electric motor whether both drive units or only one is used to drive the drive train.
