Description

Automatqetriebe, Baueinheit sowie Kraftfahrzeug  Automatqetriebe, assembly and motor vehicle
Die Erfindung betrifft ein Automatgetriebe mit wenigstens zwei Planetensätzen, aufweisend wenigstens eine Kupplung zum Schalten von Gängen. The invention relates to an automatic transmission with at least two planetary gear sets, comprising at least one clutch for shifting gears.
Es sind mehrere Arten von automatisch schaltbaren Kraftfahrzeuggetrieben im Gegensatz zu Handschaltgetrieben bekannt. Die lange Zeit verbreiteste Variante sind Automatgetriebe, die zur Realisierung der Gangstufen Planetensätze aufweisen. Diese werden über Kupplungen und Bremsen so geschaltet, dass die verschiedenen Gangstufen entstehen. There are several types of automatically switchable motor vehicle transmissions in contrast to manual transmissions known. The longest common variant are automatic transmissions, which have gear sets for realizing the gear stages. These are switched via clutches and brakes so that the different gear steps arise.
Darüber hinaus kommen verstärkt Doppelkupplungsgetriebe zum Einsatz. Diese weisen neben zwei Teilgetrieben auch zwei Kupplungen auf. Dadurch wird eine zug- kraftunterbrechungsfreie Schaltung ermöglicht. Die Doppelkupplungsgetriebe können verschiedene Bauweisen besitzen, gemeinsam ist ihnen jedoch wenigstens eine Vorgelegewelle. Es sind Doppelkupplungsgetriebe bekannt, die im Drehmomentfluss vor oder hinter den Teilgetrieben auch einen Planetensatz aufweisen können. Dieser realisiert ein Gruppengetriebe, so dass die Gangzahl der durch die Teilgetriebe dargestellten Gänge mittels des Planetensatzes verdoppelt oder verdreifacht werden kann. In addition, increasingly double-clutch transmissions are used. In addition to two partial transmissions, these also have two clutches. This allows a traction interruption-free circuit. The dual-clutch transmissions may have different designs, but at least they have at least one countershaft. There are known dual-clutch transmission, which may also have a planetary gear set in the torque flow in front of or behind the partial transmissions. This realizes a group transmission, so that the number of turns of the gears represented by the partial transmissions can be doubled or tripled by means of the planetary gear set.
Weiterhin sind automatisierte Schaltgetriebe bekannt. Diese umfassen einen Kupp- lungsaktuator und einen Getriebeaktuator, so dass ein Handschaltgetriebe durch die Verwendung der beiden Aktuatoren ohne großen Aufwand ein Handschaltgetriebe in ein automatisch schaltbares Kraftfahrzeuggetriebe umgewandelt werden kann. Furthermore, automated manual transmission are known. These include a clutch actuator and a transmission actuator, so that a manual transmission can be easily converted by the use of the two actuators, a manual transmission in an automatically switchable motor vehicle transmission.
Die vorliegende Anmeldung betrifft allerdings nur den erstgenannten Typ von automatisch schaltbaren Kraftfahrzeuggetrieben, nämlich die Automatgetriebe. Ein derartiges Getriebe geht beispielsweise aus der DE 199 12 480 A1 hervor. Die DE 103 33 429 A1 zeigt ein Mehrstufen-Automatgetriebe im Querschnitt. However, the present application relates only to the former type of automatically switchable motor vehicle transmissions, namely the automatic transmission. Such a transmission can be seen for example from DE 199 12 480 A1. DE 103 33 429 A1 shows a multi-stage automatic transmission in cross section.
Die Betätigungseinheiten der Kupplungen wie auch der Bremsen eines Automatgetriebes sind üblicherweise hydraulisch betätigt, bekannte Kupplungen besitzen einen druckbeaufschlagbaren Kolben, mit dem die Kupplungen eingerückt werden. Die Kupplungen und auch die Bremsen in einem Automatgetriebe sind also„normally open"-Kupplungen. Zum Betätigen der Kupplungen wird dabei ein Betätigungsmedium benötigt, das üblicherweise durch die Wellen zugeführt wird. Hierfür sind Drehdurchführungen vorhanden, an denen Leckageverluste auftreten können. The actuators of the clutches as well as the brakes of an automatic transmission are usually hydraulically actuated, known clutches have a pressurizable piston, with which the clutches are engaged. The clutches and also the brakes in an automatic transmission are thus "normally open" couplings, for actuating the clutches an actuating medium is required, which is usually supplied by the shafts, for which there are rotary feedthroughs at which leakage losses can occur.
Daher liegt der vorliegenden Anmeldung die Aufgabe zugrunde, ein Automatgetriebe, anzugeben, bei dem die Ölzuführung vereinfacht ist. Therefore, the present application has the object, an automatic transmission to specify, in which the oil supply is simplified.
Zur Lösung des Problems wird ein Automatgetriebe der eingangs genannten Art vorgeschlagen, dass sich dadurch auszeichnet, dass die Betätigungseinheit der Kupplung oder der Kupplungen ein Betätigungslager aufweist. To solve the problem, an automatic transmission of the type mentioned is proposed that is characterized in that the actuating unit of the clutch or clutches has an actuating bearing.
Das Betätigungslager ermöglicht es, einen Teil der Betätigungseinheit von der Mitrotation zu entkoppeln und so die Ölzuführung abändern zu können. The actuating bearing makes it possible to decouple a part of the actuating unit from the co-rotation and thus to be able to modify the oil supply.
Dabei kann das Betätigungslager bevorzugt als Kugellager, insbesondere las In this case, the actuating bearing preferably as a ball bearing, in particular las
Schrägkugellager, ausgebildet sein. Alternativ kann das Betätigungslager als Axialnadellager ausgeführt sein. Die Betätigungslager unterschiedlicher Kupplungen können gleich sein, es können aber auch unterschiedliche Betätigungslager kombiniert werden. Bei zwei Kupplungen zum Schalten von Gängen kann also ein Betätigungslager als Schrägkugellager und das andere als Axialnadellager ausgeführt sein. Angular contact ball bearings, be formed. Alternatively, the actuating bearing can be designed as an axial needle bearing. The actuation bearing different couplings may be the same, but it can also be combined different actuation bearings. In two clutches for shifting gears so an actuation bearing can be designed as angular contact ball bearings and the other as an axial needle bearing.
Weiter bevorzugt kann das Betätigungslager zwischen einem gehäusefesten Abschnitt und einem drehbaren Abschnitt der Betätigungseinheit angeordnet sein. Als gehäusefest wird dabei jedes Bauteil angesehen, dass direkt oder indirekt am Gehäuse abgestützt ist. Das heißt nicht, dass der gehäusefeste Abschnitt absolut unbeweglich ist, vielmehr kann er beispielsweise in axialer Richtung verschiebbar sein. Der drehbare Abschnitt der Betätigungseinheit ist nicht nur drehbar, sondern ebenfalls in axialer Richtung beweglich. Das Einrücken einer Kupplung erfolgt dann durch axiale Bewegung sowohl des gehäusefesten Abschnitts wie auch des drehbaren Abschnitts der Betätigungseinheit. Es sei an dieser Stelle darauf hingewiesen, dass in dem Automatgetriebe nicht nur eine einzige Kupplung zum Schalten von Gängen vorhanden sein kann, sondern grundsätzlich beliebig viele. Die beschriebene Ausgestaltung der Kupplung kann dabei an einer einzigen, an einem beliebigen Teil oder auch an allen Kupplungen realisiert sein. Dies betrifft dann nicht nur die Kupplungen zum Schalten von Gängen, sondern auch andere im Getriebe vorhandene Kupplungen. More preferably, the actuating bearing between a housing fixed portion and a rotatable portion of the actuator unit may be arranged. In this case, each component that is supported directly or indirectly on the housing is considered to be fixed to the housing. This does not mean that the housing-fixed portion is absolutely immobile, but it may, for example, be displaced in the axial direction. The rotatable portion of the operating unit is not only rotatable, but also movable in the axial direction. The engagement of a clutch is then carried out by axial movement of both the housing-fixed portion as well as the rotatable portion of the actuator unit. It should be noted at this point that in the automatic transmission not only a single clutch for shifting gears can be present, but basically any number. The described embodiment of the coupling can be realized on a single, on any part or on all couplings. This affects not only the clutches for shifting gears, but also other clutches in the transmission.
Mit Getriebe ist in Bezug auf die Erfindung immer ein Automatgetriebe angesprochen. With gear always an automatic transmission is addressed in relation to the invention.
Vorteilhafterweise kann ein gehäusefester Abschnitt der Kupplung an einer Wand des Getriebes gelagert sein. Die Wand ist dabei vorteilhafterweise als Zwischenwand ausgebildet, d. h. dass sie das Getriebe in zwei Teilräume unterteilt. Die Wand steht damit senkrecht zur Längsachse des Getriebes. Die Wand kann die Teilräume des Getriebes öldicht voneinander trennen, sie kann aber auch öldurchlässig sein. Dies gilt selbstverständlich für jedes im Getriebe befindliche Medium, üblicherweise wird jedoch ein Getriebeöl verwendet. Advantageously, a housing-fixed portion of the coupling can be mounted on a wall of the transmission. The wall is advantageously designed as an intermediate wall, d. H. that it divides the transmission into two subspaces. The wall is thus perpendicular to the longitudinal axis of the transmission. The wall can separate the subspaces of the transmission oil-tight, but it can also be oil-permeable. This of course applies to any medium in the transmission, but usually a transmission oil is used.
Mit besonderem Vorteil kann die Versorgungsleitung der Betätigungseinheit zumindest in einem Abschnitt vor der Betätigungseinheit durch eine Wand des Getriebes führen. Dabei handelt es sich bevorzugt um die Wand, die einen gehäusefesten Abschnitt der Kupplung lagert. Diese kann wie beschrieben ausgebildet sein. Durch diesen Aufbau wird eine besonders einfache Ausgestaltung der Ölzuführung für die Betätigungseinheit möglich, da die Wand durch zwei einfache Bohrungen die Zuführfunktion für das Öl erfüllen kann und der gehäusefeste Abschnitt der Betätigungseinheit sehr einfach öl- und druckdicht mit der Wand verbindbar ist. Dadurch kann auf die Ölzuführung in der Welle, insbesondere der Antriebswelle verzichtet werden, weswegen sich deren Aufbau vereinfacht. With particular advantage, the supply line of the actuating unit, at least in a section in front of the operating unit lead through a wall of the transmission. This is preferably the wall which supports a housing-fixed portion of the coupling. This can be designed as described. By this construction, a particularly simple embodiment of the oil supply for the actuator unit is possible because the wall can meet the supply function for the oil through two simple holes and the housing-fixed portion of the actuator unit is very easy oil and pressure-tight connected to the wall. As a result, can be dispensed with the oil supply in the shaft, in particular the drive shaft, which is why their structure is simplified.
Dabei kann die Wand vorzugsweise nicht nur eine Versorgungsleitung aufnehmen, sondern auch die Versorgungsleitungen weiterer Kupplungen oder auch von wenigstens einer Bremse. D. h., dass alle wandnahen Kupplungen und Bremsen zumindest einen Teil ihrer Versorgungsleitung in der Wand haben können. Dabei kann die Versorgungsleitung der Kupplung und/oder der Bremse die Wand zumindest teilweise senkrecht zur Längsachse des Getriebes durchqueren. Bevorzugt verläuft der größere Teil der Versorgungsleitung der Kupplung, der die Wand durchquert, senkrecht zur Längsachse des Getriebes. Der kleinere Teil kann parallel zur Längsachse des Getriebes verlaufen. Der senkrecht zur Längsachse des Getriebes verlaufende Teil der Versorgungsleitung verläuft bevorzugt wiederum zum größeren Teil vertikal, das heißt im montierten Zustand von oben nach unten. Die Versorgungsleitungen können auch schräg verlaufen. Gerade verlaufende Versorgungsleitungen sind aber leichter zu bohren. In this case, the wall can preferably not only receive a supply line, but also the supply lines of other couplings or at least one brake. That is, all wall-mounted clutches and brakes can have at least part of their supply line in the wall. In this case, the supply line of the clutch and / or the brake at least partially pass through the wall perpendicular to the longitudinal axis of the transmission. Preferably, the greater part of the supply line of the coupling, which traverses the wall, runs perpendicular to the longitudinal axis of the transmission. The smaller part can run parallel to the longitudinal axis of the transmission. The perpendicular to the longitudinal axis of the transmission extending part of the supply line preferably again runs for the greater part vertically, that is, in the assembled state from top to bottom. The supply lines can also run diagonally. Straight running supply lines are easier to drill.
Bevorzugt kann das Automatgetriebe wenigstens zwei Kupplungen zum Schalten von Gängen aufweisen. Besonders bevorzugt kann das Automatgetriebe genau zwei Kupplungen zum Schalten von Gängen umfassen. The automatic transmission may preferably have at least two clutches for shifting gears. Particularly preferably, the automatic transmission can comprise exactly two clutches for shifting gears.
Diese Kupplungen können koaxial und axial zumindest teilweise überlappend angeordnet sein. These couplings can be arranged coaxially and axially at least partially overlapping.
Mit besonderem Vorteil können die Betätigungseinheiten beider Kupplungen ein Betätigungslager aufweisen. Somit kann die Ölzuführung für beide Kupplungen vereinfacht werden. With particular advantage, the actuation units of both clutches can have an actuating bearing. Thus, the oil supply for both clutches can be simplified.
Vorteilhafterweise kann der Innenlamellenträger der radial äußeren Kupplung gleichzeitig der Außenlamellenträger der radial inneren Kupplung sein. Durch die Doppelbelegung kann ein Lamellenträger komplett eingespart werden. Dies ist möglich, obwohl die Kupplungen voneinander völlig unabhängig sind. Selbst wenn beide Kupplungen geschlossen sind, übertragen sie das Drehmoment von der Eingangswelle weiter, was keinerlei völlig unabhängig voneinander betreibbare Kupplungen erfordert. Advantageously, the inner disk carrier of the radially outer clutch can be simultaneously the outer disk carrier of the radially inner clutch. Due to the double assignment, a plate carrier can be completely saved. This is possible although the couplings are completely independent of each other. Even when both clutches are closed, they transmit the torque from the input shaft further, which does not require fully independently operable clutches.
Vorteilhafterweise kann der Innenlamellenträger der radial äußeren Kupplung drehfest mit einer Antriebswelle des Getriebes verbunden sein. Ist der Innenlamellenträger der radial äußeren Kupplung gleichzeitig der Außenlamellenträger der radial in- neren Kupplung, so gilt dies dann automatisch auch für den Außenlamellentrager. Der Innenlamellenträger der radial äußeren Kupplung ist damit ein eingangsseitiger oder antriebsseitiger Lamellenträger. Advantageously, the inner disk carrier of the radially outer coupling may be non-rotatably connected to a drive shaft of the transmission. Is the inner disk carrier of the radially outer clutch at the same time the outer disk carrier of the radial inner neren clutch, then this is automatically true for the outer disk carrier. The inner disk carrier of the radially outer clutch is thus an input-side or drive-side disk carrier.
Vorteilhafterweise kann der Innenlamellenträger der radial inneren Kupplung drehfest mit einer Hohlwelle, insbesondere einer Hohlwelle des ersten Planetensatzes, verbunden sein. Besonders bevorzugt kann der Innenlamellenträger der radial inneren Kupplung drehfest mit dem Steg des ersten Planetensatzes verbunden sein. Wie bereits mehrfach ausgeführt dienen die Kupplungen auch dem Schalten von Gängen. Dementsprechend müssen sie Wellen miteinander verbinden, so dass hierüber Drehmomente übertragen wird. Bei der beschriebenen Anordnung wird das Drehmoment von der Eingangswelle über eine Kupplung auf den Steg des ersten Planetensatzes verbunden. Advantageously, the inner disk carrier of the radially inner clutch rotatably connected to a hollow shaft, in particular a hollow shaft of the first planetary gear set, be connected. Particularly preferably, the inner disk carrier of the radially inner clutch may be non-rotatably connected to the web of the first planetary gearset. As already stated several times, the clutches also serve to shift gears. Accordingly, they must connect shafts together, so that this torque is transmitted. In the described arrangement, the torque from the input shaft via a coupling to the web of the first planetary gear set is connected.
Vorteilhafterwiese kann der Außenlamellenträger der radial äußeren Kupplungen drehfest mit einer Hohlwelle, insbesondere einer Hohlwelle des ersten Planetensatzes, verbunden sein. Besonders bevorzugt kann der Außenlamellenträger drehfest mit dem Sonnenrad des ersten Planetensatzes verbunden sein. Über die Kupplungen kann der erste Planetensatz also entweder über den Steg und/oder das Sonnenrad mit der Antriebswelle verbunden werden. Advantageously, the outer disk carrier of the radially outer clutches can be non-rotatably connected to a hollow shaft, in particular a hollow shaft of the first planetary gear set. Particularly preferably, the outer disk carrier rotatably connected to the sun gear of the first planetary gear set. About the clutches of the first planetary gear set can thus be connected to the drive shaft either via the web and / or the sun gear.
Vorteilhafterweise kann ein drehbarer Abschnitt der Betätigungseinheit einen Lamellenträger durchgreifen. Sind zwei Kupplungen vorhanden, die radial ineinander geschachtelt sind, greift bevorzugt der drehbare Abschnitt der Betätigungseinheit der radial inneren Kupplung durch den Außenlamellenträger der radial inneren Kupplung hindurch. Dieser kann, wie oben beschrieben, gleichzeitig der Innenlamellenträger der radial äußeren Kupplung sein. Die Betätigungseinheit bzw. der drehbare Abschnitt der Betätigungseinheit der radial inneren Kupplung und der Außenlamellenträger der radial inneren Kupplung drehen sich also gleichförmig. Advantageously, a rotatable section of the actuating unit can pass through a plate carrier. If two clutches are present, which are nested radially into one another, the rotatable section of the actuating unit of the radially inner clutch preferably engages through the outer disk carrier of the radially inner clutch. This can, as described above, simultaneously be the inner disk carrier of the radially outer coupling. The actuating unit or the rotatable portion of the actuating unit of the radially inner clutch and the outer disk carrier of the radially inner clutch thus rotate uniformly.
Vorzugsweise kann ein Rückstellelement die Betätigungseinheit in Richtung Ausrücken vorspannen. Besonders bevorzugt kann das Rückstellelement als Tellerfeder ausgebildet sein. Mit der Tellerfeder wird die Betätigungseinheit zurückgestellt, sobald der Betätigungsdruck des Betätigungsmediums nachlässt. Preferably, a return element bias the operating unit in the direction of disengagement. Particularly preferably, the return element can be used as a plate spring be educated. With the diaphragm spring, the actuator unit is reset as soon as the operating pressure of the actuating medium decreases.
Vorteilhafterweise kann das Automatgetriebe einer Kupplung zum Anbinden eines Antriebsmotors, insbesondere eines Elektromotors oder eines Verbrennungsmotors, an ein Getriebeelement, insbesondere einer Antriebswelle des Automatgetriebes aufweisen. Eine Kupplung zum Anbinden eines Verbrennungsmotors an den Antriebsstrang eines Kraftfahrzeugs ist grundsätzlich bekannt. Die Kupplung wird dabei benötigt, um die Last vom Getriebe nehmen zu können. Advantageously, the automatic transmission of a clutch for connecting a drive motor, in particular an electric motor or an internal combustion engine, to a transmission element, in particular a drive shaft of the automatic transmission. A clutch for connecting an internal combustion engine to the drive train of a motor vehicle is known in principle. The clutch is needed to take the load off the gearbox.
Wie weiter oben bereits beschrieben, können die beschriebenen Ausgestaltungen nicht nur für die Kupplungen zum Schalten von Gängen verwendet werden, sondern bevorzugt auch für die Kupplung zum Anbinden eines Antriebsmotors. Dementsprechend kann auch die Kupplung zum Anbinden eines Antriebsmotors eine Betätigungseinheit mit einem Betätigungslager besitzen. As already described above, the described embodiments can be used not only for the clutches for shifting gears, but also preferably for the clutch for connecting a drive motor. Accordingly, the coupling for connecting a drive motor may also have an actuating unit with an actuating bearing.
Vorteilhafterweise kann die Einrückbewegung der Kupplung zum Anbinden eines Antriebsmotors und der wenigstens einer Kupplung zum Schalten von Gängen in axial entgegengesetzter Richtung verlaufen. Die Kupplung zum Anbinden eines Antriebsmotors und die Kupplung oder Kupplungen zum Schalten von Gängen sind üblicherweise räumlich beabstandet. Weiterhin ist bei mehreren Kupplungen zum Schalten von Gängen zumeist lediglich eine eingerückt, im Gegensatz zur Kupplung zum Anbinden eines Antriebsmotors, die fast durchgehend eingerückt sein kann. Durch die beschriebene Anordnung können die im Getriebe axial wirkenden Kräfte zumindest teilweise gegeneinander abgestützt werden, da sowohl die Kupplung zum Anbinden eines Antriebsmotors als auch die Kupplung zum Schalten von Gängen beim Einrücken Axialkräfte auf die sie lagernden Bauteile ausüben. Durch eine Lagerung derart, dass die Einrückbewegung in entgegengesetzten Richtung verlaufen, kann eine Kompensation der Axialkräfte zumindest teilweise erreicht werden. Dies ist besonders dann gegeben, wenn die Kupplung zum Anbinden eines Antriebsmotors an dem gleichen Getriebebauteil gelagert ist wie die wenigstens eine Kupplung zum Schalten von Gängen. Insbesondere kann die Kupplung zum Anbinden eines Antriebsmotors an einer Wand des Getriebes gelagert sein. Hierbei kann es sich um die oben beschriebene Wand zur Lagerung der gehäusefesten Abschnitte der Betätigungseinheiten der Kupplung zum Schalten von Gängen handeln. Advantageously, the engagement movement of the clutch for connecting a drive motor and the at least one clutch for shifting gears can run in the axially opposite direction. The clutch for connecting a drive motor and the clutch or clutches for shifting gears are usually spatially spaced. Furthermore, with multiple clutches for shifting gears, usually only one is engaged, as opposed to the clutch for connecting a drive motor which may be engaged almost continuously. By the described arrangement, the forces acting axially in the transmission can be at least partially supported against each other, since both the clutch for connecting a drive motor and the clutch for shifting gears when engaging exert axial forces on the components they support. By a storage such that the engagement movement in the opposite direction, a compensation of the axial forces can be achieved at least partially. This is especially true when the clutch is mounted for connecting a drive motor to the same transmission component as the at least one clutch for shifting gears. In particular, the coupling may be mounted for connecting a drive motor to a wall of the transmission. This may be the above described wall for supporting the housing fixed portions of the operating units of the clutch for shifting gears.
Vorteilhafterweise kann eine Welle, insbesondere einer Antriebswelle, an der Wand über ein Lager, insbesondere ein Rillenkugellager abgestützt sein. Gerade bei einer Abstützung über ein Lager ist die teilweise Aufhebung der Axialkräfte der Betätigungseinheiten der Kupplungen besonders vorteilhaft. Advantageously, a shaft, in particular a drive shaft, be supported on the wall via a bearing, in particular a deep groove ball bearing. Especially with a support via a bearing, the partial cancellation of the axial forces of the actuators of the clutches is particularly advantageous.
Vorzugsweise kann ein drehbarer Abschnitt der Betätigungseinheit der Kupplung zum Anbinden eines Verbrennungsmotors einen Rotorträger eines Elektromotors durchgreifen. Dies kann in einem Hybridfahrzeug vorkommen, bei dem ein Rotor einer elektrischen Maschine an der Sekundärseite der Kupplung zum Anbinden und Trennen des Verbrennungsmotors drehfest angebunden ist. D. h., dass der Rotorträger und der drehbare Abschnitt der Betätigungseinheit der Kupplung drehverbunden sind. Dementsprechend wird eine Verschiebung des Rotorträgers gegenüber der Betätigungseinheit bzw. dem drehbaren Abschnitt vermieden. Preferably, a rotatable portion of the actuating unit of the clutch for connecting an internal combustion engine can pass through a rotor carrier of an electric motor. This can occur in a hybrid vehicle, in which a rotor of an electric machine on the secondary side of the clutch for connecting and disconnecting the internal combustion engine is rotatably connected. That is, the rotor carrier and the rotatable portion of the operating unit of the clutch are rotationally connected. Accordingly, a displacement of the rotor carrier relative to the actuating unit or the rotatable portion is avoided.
Weiterhin kann auch die Betätigungseinheit der Kupplung zum Schalten von Gängen drehfest mit einem Lamellenträger verbunden sein. In einer ersten Ausgestaltung kann die Verbindung durch Formschluss erfolgen, beispielsweise in dem der drehbare Abschnitt einer Betätigungseinheit einen Lamellenträger durchgreift, wie oben beschrieben. Alternativ kann die Verbindung mittels einer Verzahnung erfolgen. Furthermore, the operating unit of the clutch for shifting gears can be rotatably connected to a plate carrier. In a first embodiment, the connection can be made by positive engagement, for example, in which the rotatable portion of an actuating unit passes through a plate carrier, as described above. Alternatively, the connection can be made by means of a toothing.
Besonders bevorzugt ist vorgesehen, dass bei zwei Kupplungen zum Schalten von Gängen, die radial geschachtelt angeordnet sind, der drehbare Abschnitt der Betätigungseinheit der äußeren Kupplung mit einer Verzahnung drehfest an den Innenla- mellenträger der radial äußeren Kupplung angebunden ist, während der drehbare Abschnitt der Betätigungseinheit der radial inneren Kupplung dann eben an diesen Lamellenträger durch Formschluss über den Durchgriff angebunden ist. It is particularly preferably provided that in two clutches for shifting gears, which are arranged radially nested, the rotatable portion of the operating unit of the outer clutch with a toothing rotatably connected to the inner disk carrier of the radially outer coupling, while the rotatable portion of the actuating unit The radially inner clutch is then just connected to this plate carrier by positive engagement on the penetration.
Weiterhin ist bevorzugt vorgesehen, dass die Betätigungseinheit der Kupplung zum Schalten von Gängen in Richtung Abtrieb einrückt. Dem gegenüber kann die Kupplung zum Anbinden eines Antriebsmotors in Richtung Antrieb einrücken. Wie beschrieben weist das Automatgetriebe bevorzugt genau zwei Kupplungen zum Schalten von Gängen auf. Diese lassen sich dann radial ineinander schachteln, wodurch der axiale Bauraum minimiert wird. Weiterhin kann das Automatgetriebe drei Bremsen aufweisen. Furthermore, it is preferably provided that the actuating unit engages the clutch for shifting gears in the direction of the output. On the other hand, the clutch can engage in the direction of the drive for connecting a drive motor. As described, the automatic transmission preferably has exactly two clutches for shifting gears. These can then be nested radially into each other, whereby the axial space is minimized. Furthermore, the automatic transmission can have three brakes.
Die Kupplung oder die Kupplungen und/oder die Bremsen sind bevorzugt als Lamellenkupplungen ausgeführt. Der Unterschied zwischen einer Bremse und einer Kupplung liegt darin, dass ein Kupplung zwei Wellen miteinander verbindet, während eine Bremse eine Welle und ein Gehäuse verbindet. The clutch or clutches and / or the brakes are preferably designed as multi-plate clutches. The difference between a brake and a clutch is that a clutch connects two shafts while a brake connects a shaft and a housing.
Bevorzugt ist die Kupplung oder sind die Kupplungen nasslaufend. Preferably, the clutch or the clutches are wet-running.
Bevorzugt kann das Automatgetriebe wenigstens eine gehäusenahe Welle aufweisen und wenigstens ein Lamellenträger an der Welle abgestützt und/oder drehfest angebunden sein. Die beschriebene Anordnung ist besonders einfach an einer gehäusenahen Welle zu realisieren. Die Welle kann selbst an der beschriebenen Wand abgestützt sein. Preferably, the automatic transmission can have at least one shaft close to the housing and at least one disk carrier can be supported on the shaft and / or connected in a torque-proof manner. The described arrangement is particularly easy to implement on a shaft close to the housing. The shaft can itself be supported on the described wall.
Daneben betrifft die Erfindung eine vormontierte Baueinheit für ein Automatgetriebe. Dieses zeichnet sich dadurch aus, dass es wenigstens eine Wand, wenigstens zwei Betätigungseinheiten und wenigstens einen Lamellenträger umfasst. Bevorzugt um- fasst die Baueinheit wenigstens zwei Lamellenpakete. Die Lamellenpakete können grundsätzlich auch an einem anderen Getriebeabschnitt vormontiert sein. In addition, the invention relates to a preassembled unit for an automatic transmission. This is characterized in that it comprises at least one wall, at least two actuator units and at least one disc carrier. Preferably, the structural unit comprises at least two disk packs. The disk packs can in principle also be preassembled on another transmission section.
Besonders bevorzugt weist die Baueinheit drei Betätigungseinheiten und drei Lamellenpakete auf. Die Lamellenpakete umfassen dabei die Innenlamellen wie auch die Außenlamellen. Particularly preferably, the structural unit has three actuator units and three plate packs. The disk packs include the inner disks as well as the outer disks.
Weiterhin kann die Baueinheit zumindest einen Teil der Kupplung zum Anbinden eines Antriebsmotors, insbesondere Verbrennungsmotors, und zumindest einen Teil eines Elektromotors umfassen. Vorteilhafterweise kann die vormontierte Baueinheit alle gehäusefesten Abschnitte der Betätigungsseiten aller Kupplungen sowie aller Lamellenpakete aller Kupplungen des Automatgetriebes umfassen. Furthermore, the assembly may comprise at least a part of the coupling for connecting a drive motor, in particular internal combustion engine, and at least part of an electric motor. Advantageously, the preassembled unit all housing-fixed sections of the actuation sides of all couplings and all disc packs of all couplings of the automatic transmission include.
Vorzugsweise kann die Wand wenigstens zwei Teile aufweisen, die miteinander verschraubt sind. Dadurch lassen sich die Versorgungsleitungen für die Betätigungseinheiten besonders einfach einbringen. Preferably, the wall may comprise at least two parts which are screwed together. As a result, the supply lines for the actuators can be particularly easy to bring.
Daneben betrifft die Erfindung ein Kraftfahrzeug. Dieses weist ein Automatgetriebe wie beschrieben oder eine vormontierte Baueinheit wie beschrieben auf. In addition, the invention relates to a motor vehicle. This has an automatic transmission as described or a preassembled unit as described.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen und Figuren. Dabei zeigen: Further advantages, features and details of the invention will become apparent from the following description of exemplary embodiments and figures. Showing:

Figur 1 zeigt ein Radsatzschema 1 für ein Automatgetriebe, das für das beschriebene Automatgetriebe passend ist. Dieses ähnelt dem aus der DE 199 12 480 A1 bekannten Schema, weist jedoch auch einige Abweichungen auf. Der Radsatz umfasst einen ersten Planetensatz 2, einen zweiten Planetensatz 3 und einen dritten Planetensatz 4. Als Schaltelemente sind Kupplungen 5 und 6 sowie Bremsen 7, 8 und 9 vorgesehen. Dabei sind insbesondere nicht nur die Kupplungen 5 und 6 zum Schalten von Gängen sondern auch die Kupplung 10 zum Anbinden eines Antriebsmotors in Form eines Verbrennungsmotors außerhalb der Planetensätze 2, 3 und 4 ange- ordnet. Außerhalb der Planetensätze 2, 3 und 4 bedeutet dabei, dass die Kupplungen, insbesondere die Kupplungen 5 und 6, nicht zwischen den Planetensätzen 2 und 3 oder 3 und 4 liegen. Dies trifft sowohl für die räumliche Anordnung zu, im Schema könnte die Kupplung 6 oder auch die Kupplung 5 innerhalb der Planetensätze gezeichnet sein, ohne dass sich ihre Platzierung verändert. In Figur 1 ist die Kupplung 6 aber auch außerhalb der Planetensätze 2, 3 und 4 dargestellt. Figure 1 shows a Radsatzschema 1 for an automatic transmission, which is suitable for the described automatic transmission. This is similar to the scheme known from DE 199 12 480 A1, but also has some deviations. The wheelset comprises a first planetary gearset 2, a second planetary gearset 3 and a third planetary gearset 4. As shifting elements, clutches 5 and 6 as well as brakes 7, 8 and 9 are provided. In particular, not only the clutches 5 and 6 for shifting gears but also the clutch 10 for connecting a drive motor in the form of an internal combustion engine outside of the planetary gear sets 2, 3 and 4 ange- assigns. Outside the planetary gear sets 2, 3 and 4 means that the clutches, in particular the clutches 5 and 6, do not lie between the planetary gear sets 2 and 3 or 3 and 4. This applies both to the spatial arrangement, in the scheme, the clutch 6 or the clutch 5 could be drawn within the planetary gear sets without their placement changed. In Figure 1, the clutch 6 but also outside the planetary gear sets 2, 3 and 4 is shown.
Figur 2 zeigt einen ersten für die Erfindung relevanten Teil des Automatgetriebes 1 1 , dabei sind die Planetensätze 2, 3 und 4 nicht mehr dargestellt. Und auch von den Bremsen ist lediglich die Bremse 7 zu erkennen. Die Kupplungen 5 und 6 sind radial ineinander geschachtelt. Das heißt, sie sind koaxial angeordnet und in axialer Richtung zumindest teilweise überlappend. Die radial äußere Kupplung 5 umfasst einen Lamellenträger 14 als Innenlamellenträger, einen Au ßenlamellenträger 1 6, ein Lamellenpaket 18 umfassend abwechselnd Innen- und Außenlamellen sowie eine Betätigungseinheit 20. Die Betätigungseinheit 20 umfasst einen gehäusefesten Abschnitt 22 bestehend aus einem Betätigungskolben 24 sowie einem tellerartigen Kolbenabschnitt 26. An den gehäusefesten Abschnitt 22, und zwar an den tellerartigen Kolbenabschnitt 26, schließt ein Betätigungslager 28 als Einrücklager an. Weiterhin umfasst die Kupplung 5 einen drehbaren Abschnitt 30, der aus einem Verbindungsteller 32 und einem Druckteller 34 besteht. Der Lamellenträger 14 weist an seinem wellen- abgewandten Ende gleichzeitig einen Anschlag für das Lamellenpaket 18 auf. Figure 2 shows a first relevant to the invention part of the automatic transmission 1 1, while the planetary gear sets 2, 3 and 4 are no longer shown. And also of the brakes only the brake 7 can be seen. The clutches 5 and 6 are nested radially in one another. That is, they are arranged coaxially and at least partially overlapping in the axial direction. The radially outer clutch 5 comprises a disk carrier 14 as an inner disk carrier, an outer disk carrier 1 6, a disk pack 18 comprising alternating inner and outer disks and an actuating unit 20. The actuating unit 20 comprises a housing-fixed section 22 consisting of an actuating piston 24 and a plate-like piston section 26 To the housing-fixed portion 22, and that to the plate-like piston portion 26, an actuating bearing 28 connects as an engagement bearing. Furthermore, the coupling 5 comprises a rotatable section 30, which consists of a connection plate 32 and a pressure plate 34. At the same time, the disk carrier 14 has a stop for the disk pack 18 at its end remote from the shaft.
Der Lamellenträger 14 ist gleichzeitig der Außenlamellenträger der Kupplung 6. Weiterhin umfasst die Kupplung 6 analog zu Kupplung 5 einen Innenlamellenträger 36, ein Lamellenpaket 38, eine Betätigungseinheit 39 umfassend einen gehäusefesten Abschnitt 40 mit Betätigungskolben 42 und tellerartigen Kolbenabschnitt 44, ein Betätigungslager 46 sowie ein drehbarer Abschnitt 48. Der drehbare Abschnitt 48 weist einen Druckteller 50 auf, der analog zu Kupplung 5 einen außenliegenden Verbindungsteller kontaktiert. The disk carrier 14 is at the same time the outer disk carrier of the clutch 6. Furthermore, the clutch 6 comprises, analogous to clutch 5, an inner disk carrier 36, a disk pack 38, an actuating unit 39 comprising a housing-fixed portion 40 with actuating piston 42 and plate-like piston portion 44, an actuating bearing 46 and a rotatable Section 48. The rotatable portion 48 has a pressure plate 50, which contacts analogous to clutch 5 an external connection plate.
Die Innen- und Außenringe der Lager 28 und 46 werden dabei durch den Verbindungsteller 32 und den tellerartigen Kolbenabschnitt 26 bzw. den Verbindungsteller 34 und den tellerartigen Kolbenabschnitt 44 gebildet. Diese Bauteile haben somit eine Doppelfunktion, dadurch ist das Lager 28 bzw. 46 integral in der Betätigungseinheit 20 bzw. 39 ausgebildet ist. Als Rückstellelemente weist das Automatgetriebe 1 1 Rückstellfedern 52 und 54 auf. Die gehäusefesten Abschnitte 22 und 40 sind in der Wand 12 gelagert und in dieser axial beweglich. In der Wand 12 sind dementsprechend Versorgungsleitungen 56 und 58 für die Kupplungen 5 und 6 bzw. deren Betätigungseinheiten 20 und 39 vorgesehen. Weiterhin kann in der Wand 12 auch eine Versorgungsleitung 60 für die Bremse 7 vorgesehen sein. The inner and outer rings of the bearings 28 and 46 are formed by the connecting plate 32 and the plate-like piston portion 26 and the connecting plate 34 and the plate-like piston portion 44. These components thus have a dual function, thereby the bearing 28 and 46 is integrally formed in the actuator unit 20 and 39, respectively. As restoring elements, the automatic transmission 1 1 return springs 52 and 54. The housing-fixed sections 22 and 40 are mounted in the wall 12 and axially movable in this. In the wall 12 supply lines 56 and 58 are accordingly provided for the clutches 5 and 6 and their actuators 20 and 39, respectively. Furthermore, in the wall 12, a supply line 60 may be provided for the brake 7.
Figur 3 zeigt einen zweiten Teil des Automatgetriebes 1 1 , und zwar denjenigen, der links an der Wand 12 nach Fig. 2 anschließt. Das Automatgetriebe 1 1 kann ferner eine Kupplung 64 zum Ankuppeln eines Verbrennungsmotors aufweisen. Die Kupplung 64 trägt in Fig. 1 das Bezugszeichen„10". Die Kupplung 64 liegt innerhalb eines Elektromotors 66. Der Elektromotor 66 umfasst insbesondere einen Rotor 68 und einen Stator 70. Analog zu den Kupplungen 5 und 6 umfasst die Kupplung 64 einen Innenlamellenträger 72, einen Lamellenpaket 74, einen Außenlamellenträger 76 sowie eine Betätigungseinheit 78. Die Betätigungseinheit 78 weist einen gehäusefesten Abschnitt 80 mit Betätigungskolben 82 und tellerartigen Kolbenabschnitt 84 auf. Weiterhin umfasst die Betätigungseinheit 78 ein Betätigungslager 86 sowie einen drehbaren Abschnitt 88 mit einem Verbindungsteller 90 und einem Druckteller 92. Auch eine Rückstellfeder 94 ist vorhanden. Figure 3 shows a second part of the automatic transmission 1 1, namely the one which connects to the left of the wall 12 of FIG. The automatic transmission 1 1 may further include a clutch 64 for coupling an internal combustion engine. The coupling 64 bears the reference numeral "10" in Fig. 1. The clutch 64 is located within an electric motor 66. The electric motor 66 comprises in particular a rotor 68 and a stator 70. Analogous to the clutches 5 and 6, the clutch 64 comprises an inner disk carrier 72 The actuation unit 78 has a housing-fixed section 80 with actuating piston 82 and plate-like piston section 84. Furthermore, the actuation unit 78 comprises an actuation bearing 86 and a rotatable section 88 with a connection plate 90 and a pressure plate 92. Also, a return spring 94 is present.
Der Außenlamellenträger 76 der Kupplung 64 zum Anbinden eines Verbrennungsmotors ist gleichzeitig der Rotorträger des Elektromotors 66. D.h. dass der Rotor 68 direkt drehfest auf dem Außenlamellenträger 76 angebunden ist Somit ist die Kupplung 64 in den Elektromotor 66 integriert. The outer disk carrier 76 of the clutch 64 for connecting an internal combustion engine is at the same time the rotor carrier of the electric motor 66. that the rotor 68 is connected directly to the outer disk carrier 76 in a rotationally fixed manner. Thus, the clutch 64 is integrated in the electric motor 66.
Der Kolben 82 der Kupplung 64 ist in der Wand 12 gehäusefest gelagert und dabei axial beweglich. The piston 82 of the clutch 64 is mounted fixed to the housing in the wall 12 and thereby axially movable.
Die Betätigungseinheit 78 der Kupplung 64 rückt in Richtung Antriebseinheit oder Antrieb ein, während die Kupplungen 5 und 6 in Richtung Abtrieb einrücken. Die Einrückrichtungen der Kupplungen 5 oder 6 und 64 sind damit entgegengesetzt. Die Einrückrichtungen der Kupplungen 5 und 6 sind selbstverständlich in der gleichen Richtung. The actuating unit 78 of the clutch 64 engages in the direction of the drive unit or drive while the clutches 5 and 6 engage in the direction of the output. The directions of engagement of the clutches 5 or 6 and 64 are thus opposite. The Einrückrichtungen the clutches 5 and 6 are of course in the same direction.
Auch die Versorgungsleitung 95 der Betätigungseinheit 78 führt durch die Wand 12. Also, the supply line 95 of the actuator 78 passes through the wall 12th
Die Antriebswelle 98 ist über ein Rillenkugellager 96 auf der Wand 12 abgestützt. Dadurch dass die Kupplungen 5 und 6 eine andere Einrückrichtung aufweisen als die Kupplung 64 können so die Axialkräfte auf das Rillenkugellager 96 minimiert werden. Das Rillenkugellager 98 ist vorzugsweise als Vierpunktlager mit geringem Axialspiel ausgeführt. The drive shaft 98 is supported on the wall 12 via a deep groove ball bearing 96. As a result of the fact that the clutches 5 and 6 have a different engagement direction than the clutch 64, the axial forces on the deep groove ball bearing 96 can be minimized. The deep groove ball bearing 98 is preferably designed as a four-point bearing with low axial play.
Die drehbaren Abschritte 30, 48 und 88 und insbesondere jeweils die Druckteller 34, 50 und 92 sind mit dem Lamellenträger 14 bzw. dem Außenlamellenträger 76 drehfest verbunden. Der Drehteller 34 ist dabei mit einer Verzahnung mit dem Lamellenträger 14 verbunden, während der Drehteller 50 und der Drehteller 92 in den Lamellenträger 14 bzw. 76 eingreifen bzw. diese mittels mehreren axial ausgeformten Fingern durchgreifen. Der Lamellenträger 14 wird dabei ohne den Vorsatz„Innen-" oder „Außen-" bezeichnet, da er beide Funktionen erfüllt. The rotatable Abschritte 30, 48 and 88 and in particular in each case the pressure plates 34, 50 and 92 are rotatably connected to the disk carrier 14 and the outer disk carrier 76. The turntable 34 is connected with a toothing with the plate carrier 14, while the turntable 50 and the turntable 92 engage in the plate carrier 14 and 76 or pass through this by means of several axially shaped fingers. The plate carrier 14 is referred to without the intent "inside" or "outside" because it fulfills both functions.
Der Außenlamellenträger 76 ist gleichzeitig der Rotorträger des Rotors 68. The outer disk carrier 76 is at the same time the rotor carrier of the rotor 68.
Statt eines Verbrennungsmotors kann die Kupplung 64 auch einen Elektromotor 66 anbinden. Dies ist im gezeigten Ausführungsbeispiel zwar nicht der Fall, es sind jedoch auch Konstruktionen mit derartigen Kupplungen bekannt. Es können auch mehrere Kupplungen zum Anbinden von Antriebsmotoren vorhanden sein, bspw. eine für einen Verbrennungsmotor und eine für einen Elektromotor. Instead of an internal combustion engine, the clutch 64 can also connect an electric motor 66. Although this is not the case in the illustrated embodiment, but there are also constructions known with such couplings. There may also be a plurality of clutches for connecting drive motors, for example one for an internal combustion engine and one for an electric motor.
Figur 4 zeigt einen größeren Teil des Automatgetriebes 1 1 umfassend die in den Fig. 2 und 3 gezeigten Teile. Die Bezugszeichen wurden dabei der Übersichtlichkeit halber zu einem großen Teil weggelassen. Ansonsten zeigen die Fig. 2 und 3 Bauteile, die zu denen in Fig. 4 identisch sind. Aus Fig. 4 geht insbesondere die Wand 12 insgesamt sowie die Lage der Kupplungen 5 und 6 im Vergleich zu Kupplung 64 hervor. Figur 5 zeigt eine vormontierte Baueinheit 100, die zum Einbau in das Automatgetriebe 1 1 bestimmt ist. Zur Vermeidung von Wiederholungen wird dabei auf die Beschreibung sowie die Figuren 2 bis 4 verwiesen. Gleiche Bezugszeichen bezeichnen dabei gleiche Bauteile. Dabei kann man erkennen, dass die Kupplungen 5, 6 und 64 nicht vollständig in der vormontierten Baueinheit 1 00 enthalten sind, beispielsweise fehlt bei der Kupplung 64 der Innenlamellenträger 72. Bei der Kupplung 5 ist in der vormontierten Baueinheit 100 der Außenlamellenträger 1 6 nicht enthalten und bei der Kupplung 6 der Innenlamellenträger 36. Figure 4 shows a larger part of the automatic transmission 1 1 comprising the parts shown in FIGS. 2 and 3. The reference numerals have been omitted for the sake of clarity to a large extent. Otherwise, FIGS. 2 and 3 show components which are identical to those in FIG. From Fig. 4, in particular, the wall 12 in total and the position of the couplings 5 and 6 in comparison to the coupling 64 shown. Figure 5 shows a preassembled unit 100, which is intended for installation in the automatic transmission 1 1. To avoid repetition, reference is made to the description and the figures 2 to 4. The same reference numerals designate the same components. It can be seen that the clutches 5, 6 and 64 are not completely contained in the preassembled unit 1 00, for example, is missing in the clutch 64 of the inner disk carrier 72. In the clutch 5 in the preassembled unit 100 of the outer disk carrier 1 6 is not included and in the clutch 6 of the inner disk carrier 36th
Allgemein ausgedrückt kann man sagen, dass die vormontierte Baueinheit 100 bevorzugt alle antriebsseitigen Bauteile der Kupplungen 5, 6 und/oder 64 umfasst. Weiter bevorzugt umfasst sie die Betätigungseinheiten 20, 39 und 78. Die Innen- und Außenlamellen der Lamellenpakete sind jeweils als Lamellenpaket ganz oder nicht enthalten. Die Lamellen können also als antriebsseitiges Bauteil fehlen. In general terms, it can be said that the preassembled unit 100 preferably comprises all the drive-side components of the clutches 5, 6 and / or 64. More preferably, it includes the actuator units 20, 39 and 78. The inner and outer disks of the disk packs are included as a disk pack completely or not. The slats can therefore be missing as a drive-side component.
Man erkennt, dass die Wand aus zwei miteinander verschraubten Teilen 102 und 104 besteht. Die Betätigungseinheiten 20, 39 und 78 sind dagegen vollständig in der Baueinheit 100 erhalten. Auch die Antriebswelle 98 ist vorzugsweise Teil der vormontierten Baueinheit 100. It can be seen that the wall consists of two parts 102 and 104 screwed together. The actuator units 20, 39 and 78, however, are completely obtained in the assembly 100. The drive shaft 98 is preferably part of the preassembled unit 100.
Figur 6 zeigt eine alternative Lagerausgestaltung. Dabei ist das Betätigungslager 28 der radial äußeren Kupplung 5 als Axialnadellager ausgebildet. Der Druckteller 34 ist am betätigungslagerseitigen Ende wulstförmig mit lagermittigem Anlagepunkt ausgeführt. Bevorzugt kann eine Lageranlaufscheibe vorgesehen sein. Dadurch bleibt der Kraftangriffspunkt entlang des Wulstradius auf konstanten singulärem Wirkdurchmesser. FIG. 6 shows an alternative bearing design. In this case, the actuating bearing 28 of the radially outer clutch 5 is formed as an axial needle bearing. The pressure plate 34 is executed bead-shaped with Lagermittigem contact point on the operating bearing side end. Preferably, a bearing contact disk can be provided. As a result, the force application point along the bead radius remains at a constant singular effective diameter.
Grundsätzlich kann jede der Kupplungen 5, 6 oder 64 oder jede andere Kupplung mit einem Axialnadellager oder einem Schrägkugellager ausgestattet werden. Verschiedene Kupplungen können mit unterschiedlichen Betätigungslagern ausgestattet sein, es kann auch vorgesehen sein, dass nur ein Teil der Betätigungseinheiten 20, 39 und 78 der Kupplungen 20, 39 und 78 mit einem Betätigungslager versehen ist. Bei der in Figur 6 gezeigten Ausgestaltung handelt es sich aber um eine von zwei bevorzugten Alternativen. In principle, each of the clutches 5, 6 or 64 or any other coupling can be equipped with an axial needle bearing or an angular contact ball bearing. Different clutches may be equipped with different actuating bearings, it may also be provided that only a part of the actuating units 20, 39 and 78 of the clutches 20, 39 and 78 is provided with an actuating bearing. at however, the embodiment shown in FIG. 6 is one of two preferred alternatives.
Der Übersichtlichkeit halber wurden in Fig. 6 nur die wichtigsten Bezugszeichen verwendet. Fig. 6 zeigt jedoch abgesehen von der Art des Betätigungslagers 28 die gleichen Bauteile wie Fig. 2, weswegen auf die Beschreibung dort verwiesen wird. For the sake of clarity, only the most important reference numerals have been used in FIG. Fig. 6 shows, however, apart from the type of actuating bearing 28, the same components as Fig. 2, so reference is made to the description there.
