Description

Die vorliegende Erfindung bezieht sich auf eine Drehmomentübertragungsanordnung gemäß dem Oberbegriff von Patentanspruch 1. The present invention relates to a torque transmission arrangement according to the preamble of claim 1.

Aus der EP 2 020 535 A2 ist bereits eine gattungsgemäße Drehmomentübertragungsanordnung bekannt, bei der ein auf einer Eingangswelle eines Automatgetriebes gelagerter hydrodynamischer Drehmomentwandler mittels einer flexiblen Übertragungsscheibe (Flexplate) mit der Kurbelwelle eines Verbrennungsmotors in Drehmomentübertragung steht. Der Drehmomentwandler ist dabei mittels eines Lagerzapfens in einer zentralen Lagerstelle der Kurbelwelle gelagert, wobei die Flexplate radial innen fest mit der Kurbelwelle und in deren radial äußeren Bereich mit dem Gehäuse des Drehmomentwandlers verbunden ist. Ein zwischen der Kurbelwelle des Verbrennungsmotors und der Getriebeeingangswelle auftretender Versatz bzw. ein Schiefstand wird beim Betreiben der Anordnung durch eine elastische Verformung der Flexplate aufgenommen, so dass dabei der Lagerzapfen des Drehmomentwandlers im Wesentlichen keine Zwangskräfte in dessen Lagerstelle einbringt. From the EP 2 020 535 A2 A generic torque transmission arrangement is already known in which a hydrodynamic torque converter mounted on an input shaft of an automatic transmission is in torque transmission by means of a flexible transmission disk (flexplate) with the crankshaft of an internal combustion engine. The torque converter is mounted by means of a journal in a central bearing point of the crankshaft, wherein the flexplate is fixed radially inwardly fixed to the crankshaft and in its radially outer region with the housing of the torque converter. An offset occurring between the crankshaft of the internal combustion engine and the transmission input shaft or an obliquity is received during operation of the assembly by an elastic deformation of the flexplate, so that in this case the bearing pin of the torque converter introduces substantially no constraining forces in its bearing.

Eine andere Situation liegt jedoch vor, wenn an dem Verbindungsbereich des Drehmomentwandlers eine solche vorgenannte flexible Übertragungsscheibe nicht vorliegt oder weniger flexibel ist und der Verbindungsbereich somit vergleichsweise steif ausgeführt ist. In diesem Fall kann der Lagerzapfen auf dessen Lagerstelle beträchtliche Zwangskräfte ausüben, welche eine effektive Drehmomentübertragung behindern und wodurch der Lagerzapfen über die Lebensdauer geschädigt werden kann. Another situation exists, however, if such an abovementioned flexible transfer disk is absent or less flexible at the connecting region of the torque converter and the connecting region is thus made comparatively rigid. In this case, the journal can exert considerable constraining forces on its bearing, which hinder effective torque transmission and which can damage the journal over its lifetime.

Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Drehmomentübertragungsanordnung der eingangs genannten Art so zu verbessern, dass im Betrieb gegebenenfalls an der Lagerstelle des Lagerzapfens auftretende Zwangskräfte möglichst vermieden bzw. zumindest reduziert werden. Based on this, the present invention has the object to improve a torque transmission arrangement of the type mentioned so that occurring during operation possibly occurring at the bearing point of the journal positive forces as possible avoided or at least reduced.

Diese Aufgabe wird durch eine gattungsgemäße Drehmomentübertragungsanordnung mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Die Drehmomentübertragungsanordnung umfasst zunächst ein um eine Drehachse A drehbares erstes Übertragungselement mit radial außerhalb der Drehachse angeordneten ersten Verbindungsmitteln, wobei das erste Übertagungselement zumindest mittelbar an einer ersten Funktionseinheit gelagert ist. Die Drehmomentübertragungsanordnung umfasst weiter ein um eine Drehachse B drehbares zweites Übertragungselement mit radial außerhalb der Drehachse angeordneten zweiten Verbindungsmitteln, wobei die ersten und zweiten Verbindungsmittel zur gemeinsamen Drehung des ersten und zweiten Übertragungselements gekoppelt oder koppelbar sind und wobei das zweite Übertragungselement zumindest mittelbar an einer zweiten Funktionseinheit gelagert ist. Ferner umfasst die Die Drehmomentübertragungsanordnung ein Lagerelement mit einer bezüglich der Drehachse A zentral ausgebildeten Lagerstelle, in der ein bezüglich der Drehachse B zentraler Lagerzapfen des zweiten Übertragungselements eingreift und dort gelagert ist. Die vorgeschlagene Drehmomentübertragungsanordnung ist dadurch gekennzeichnet, dass die Lagerstelle oder der Lagerzapfen ein, insbesondere in radialer Richtung verschleißfähiges Zentrierelement umfassen. This object is achieved by a generic torque transmission arrangement with the characterizing features of claim 1. The torque transmission arrangement initially comprises a first transmission element which is rotatable about a rotation axis A and has first connecting means arranged radially outside the axis of rotation, wherein the first transmission element is mounted at least indirectly on a first functional unit. The torque transmission arrangement further comprises a second transmission element rotatable about a rotation axis B with second connection means arranged radially outside the rotation axis, wherein the first and second connection means are coupled or couplable for common rotation of the first and second transmission elements and wherein the second transmission element is at least indirectly attached to a second functional unit is stored. Furthermore, the torque transmission arrangement comprises a bearing element with a bearing point which is formed centrally with respect to the axis of rotation A and in which a bearing journal of the second transmission element which is central relative to the axis of rotation B engages and is supported there. The proposed torque transmission arrangement is characterized in that the bearing point or the bearing journal comprise a centering element which is capable of wear, in particular in the radial direction.

Das Zentrierelement kann beispielweise als eine in die Lagerstelle eingesetzte oder als eine auf dem Lagerzapfen angeordnete Hülse ausgebildet sein. Der Lagerzapfen kann axial gegenüber den zweiten Verbindungsmitteln vorstehen und somit bei der Montage der Drehmomentübertragungsanordnung der gegenseitigen Zentrierung von erstem und zweitem Übertragungselement dienen, wobei das verschleißfähige Zentrierelement die dabei auftretenden Trag- und Montagekräfte sicher aufnehmen kann. Nach erfolgter Zentrierung können das erste und das zweite Übertragungselement unter Einsatz der Verbindungsmittel zur Drehmomentübertragung miteinander verbunden werden. Bei einem gegenseitigen Versatz oder Schiefstand der Drehachsen A, B kann zwar im Betrieb der Anordnung durch den Lagerzapfen zunächst eine Kraft in die Lagerstelle des Lagerelements eingeleitet werden. Aufgrund der gegebenen Verschleißfähigkeit des im Bereich der Lagerstelle an dieser oder an dem Lagerzapfen angeordneten Zentrierelements kann dieses unter dem Einfluss der dort auftretenden Radialkräfte gezielt und innerhalb einer relativ kurzen Betriebsdauer verschleißen bis der Lagerbereich im Wesentlichen frei von unerwünschten Radialkräften ist. Unter einem Verschleiß soll dabei ein Materialabtrag oder eine Verformung des Zentrierelements verstanden werden, wobei eine im Einbauzustand des Zentrierelements zunächst vorliegende Ausgangsform verändert wird. Bei einem Materialabtrag kann sich das abgetragene Material an einer anderen Stelle ablagern, während bei einer Verformung keine unerwünschte Materialablagerung auftreten kann. Bei einer Materialverformung wird lediglich überschüssiges Material in kraftfreie Bereiche verdrängt. Der Verschleiß des Zentrierelements erfolgt also nicht wie sonst üblich unerwünscht, sondern vielmehr in einer vorbestimmten und damit gezielten Art und Weise. The centering element can be designed, for example, as a sleeve inserted into the bearing or as a sleeve arranged on the journal. The bearing pin can protrude axially relative to the second connection means and thus serve in the assembly of the torque transmission arrangement of the mutual centering of the first and second transmission element, wherein the wearable centering element can safely absorb the occurring supporting and mounting forces. After centering, the first and the second transmission element can be connected to each other using the connection means for transmitting torque. In the case of a mutual offset or obliquity of the axes of rotation A, B, it is true that a force can first be introduced into the bearing point of the bearing element during operation of the arrangement by the bearing journal. Due to the given wear capacity of the arranged in the region of the bearing on this or on the bearing pin centering this can under the influence of the radial forces occurring there selectively and wear within a relatively short period of operation until the storage area is substantially free of unwanted radial forces. Wear is to be understood as meaning a removal of material or a deformation of the centering element, with a starting shape initially present in the installed state of the centering element being changed. In a material removal, the removed material may deposit at another location, while in a deformation no unwanted material deposition can occur. In a material deformation only excess material is displaced into force-free areas. The wear of the centering is thus not undesirable as usual, but rather in a predetermined and thus targeted manner.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den abhängigen Ansprüchen sowie der nachfolgenden Figurenbeschreibung entnehmbar. Advantageous embodiments and further developments of the invention are the dependent claims and the following description of the figures removed.

Gemäß einer ersten vorteilhaften Ausgestaltung kann das verschleißfähige Zentrie- relement aus einem Kunststoff gefertigt sein, beispielweise aus einem Thermoplast- oder einem Duroplastwerkstoff. According to a first advantageous embodiment, the wearable centering element may be made of a plastic, for example of a thermoplastic or a thermoset material.

Mit weiterem Vorteil können die ersten und/oder die zweiten Verbindungsmittel radial toleranzbehaftet und/oder radial flexibel ausgebildet werden, wodurch ein Verschleiß des Zentrierelements auf ein verträgliches Maß reduziert werden kann. With further advantage, the first and / or the second connecting means can be radially toleranced and / or radially flexible, whereby wear of the centering can be reduced to a tolerable level.

Gemäß einer Ausführungsform können das Lagerelement und das erste Übertragungselement drehbar zueinander gelagert sein und somit zumindest bis auf ein gegebenenfalls vorhandenes Lagerspiel radial zueinander festgelegt sein. Es ist aber jedoch grundsätzlich auch möglich, das Lagerelement und das erste Übertragungselement ohne eine feste gegenseitige Lagebeziehung anzuordnen. According to one embodiment, the bearing element and the first transmission element can be rotatably mounted to each other and thus be set radially to each other at least up to a possibly existing bearing clearance. However, it is also possible in principle to arrange the bearing element and the first transmission element without a fixed mutual positional relationship.

Im Weiteren kann gemäß einer Ausführungsform die erste Funktionseinheit als elektrische Maschine und das erste Übertragungselement als ein Rotor der elektrischen Maschine ausgebildet sein. Davon ausgehend oder unabhängig davon kann das Lagerelement als eine drehmomentübertragende Kupplungsnabe einer funktional zwischen einem Verbrennungsmotor und der elektrischen Maschine angeordneten Reibungskupplung ausgebildet sein. Dabei kann insbesondere das Lagerelement den Rotor axial zumindest teilweise durchdringen, wobei der Rotor der elektrischen Maschine und das Lagerelement gegenseitig zueinander gelagert sind. Furthermore, according to one embodiment, the first functional unit may be designed as an electrical machine and the first transmission element as a rotor of the electrical machine. Based on this or independently thereof, the bearing element can be designed as a torque-transmitting coupling hub of a friction clutch functionally arranged between an internal combustion engine and the electric machine. In this case, in particular, the bearing element axially penetrate the rotor axially at least partially, wherein the rotor of the electric machine and the bearing element are mutually supported.

Bevorzugt kann in weiterer vorteilhafter Ausgestaltung der Erfindung das zweite Übertragungselement als ein hydrodynamischer Drehmomentwandler ausgebildet sein, wobei die zweiten Verbindungsmittel an einem Gehäuse des Drehmomentwandlers ausgebildet sind und wobei das Gehäuse an einem im Drehmomentverlauf folgenden Gangwechselgetriebe gelagert ist, welches die zweite Funktionseinheit ausbildet. Preferably, in a further advantageous embodiment of the invention, the second transmission element may be formed as a hydrodynamic torque converter, wherein the second connecting means are formed on a housing of the torque converter and wherein the housing is mounted on a gear change transmission following in the torque curve, which forms the second functional unit.

Das vorgeschlagene verschleißfähige Zentrierelement kann einen hülsenförmigen Grundkörper und davon radial nach innen oder nach außen abstehende und gegenseitig in Umfangsrichtung beabstandete Vorsprünge aufweisen. Die Vorsprünge sind zumindest teilweise als verschleißende Abschnitte vorgesehen. Der Verschleißvolumen kann durch die Vorsprünge gegenüber einem umfangsmäßig geschlossenen Wandbereich gering gehalten werden, wodurch im Weiteren auch eine Einlaufzeit des Lagerzapfens an dem Zentrierelement verkürzt wird. The proposed wear-capable centering element may have a sleeve-shaped base body and protruding radially inwardly or outwardly and mutually circumferentially spaced projections. The projections are at least partially provided as wearing portions. The wear volume can be kept low by the projections with respect to a circumferentially closed wall region, which further reduces an inflow time of the journal on the centering element.

Nachfolgend wird die Erfindung anhand einer in den beigefügten Figuren dargestellten Ausführungsform beispielhaft erläutert. The invention will be explained by way of example with reference to an embodiment shown in the accompanying figures.

2 eine Detaildarstellung des Zentrierelements von 1. 2 a detailed representation of the centering of 1 ,

Die 1 zeigt eine Drehmomentübertragungsanordnung 10 eines Antriebsstranges für ein Hybridfahrzeug, welches mittels eines hier lediglich angedeuteten Verbrennungsmotors 12 und einer elektrischen Maschine 14 angetrieben werden kann. Funktional zwischen dem Verbrennungsmotor 12 und der elektrischen Maschine 14 ist eine wahlweise schaltbare Trennkupplung 16 vorgesehen, so dass das Fahrzeug entweder mit dem Verbrennungsmotor 12 oder der elektrischen Maschine 14 oder mit beiden vorgenannten Antriebsaggregaten antreibbar ist. The 1 shows a torque transmission arrangement 10 a drive train for a hybrid vehicle, which by means of an internal combustion engine only indicated here 12 and an electric machine 14 can be driven. Functional between the combustion engine 12 and the electric machine 14 is an optional switchable disconnect clutch 16 provided so that the vehicle either with the internal combustion engine 12 or the electric machine 14 or can be driven with both aforementioned drive units.

Vorliegend ist die elektrische Maschine 14 in Außenläuferbauart ausgeführt und weist ein an einem Gehäuseelement 18 festgelegten Stator 20 und einen diesen radial außen umgebenden Rotor 22 auf, welcher mittels eines Rotorträgers 24 an dem Stator 20 gelagert ist und welcher sich dort um eine Drehachse A drehen kann. Die elektrische Maschine 14 bildet somit eine erste Funktionseinheit, an der der Rotor 22 als ein erstes Übertragungselement gelagert ist. In the present case is the electric machine 14 designed in external rotor type and has a on a housing element 18 fixed stator 20 and a rotor surrounding this radially on the outside 22 on, which by means of a rotor carrier 24 on the stator 20 is mounted and which can rotate there about a rotation axis A. The electric machine 14 thus forms a first functional unit, on which the rotor 22 is stored as a first transmission element.

Es ist erkennbar, dass der Rotor 22 mit einem im Drehmomentübertragungsweg auf die elektrische Maschine 14 folgenden hydrodynamischen Drehmomentwandler 26, insbesondere über dessen Gehäuse 28 zur Drehmitnahme verbunden ist. Der Drehmomentwandler 26 wiederum ist an einem nachfolgenden Gangwechselgetriebe 30, hier einem Automatgetriebe, insbesondere an dessen Eingangswelle 32 gelagert und kann somit ein an dessen Ausgang anliegendes Drehmoment in diese Eingangswelle 32 einleiten. It can be seen that the rotor 22 with a torque transmission path to the electric machine 14 following hydrodynamic torque converter 26 , in particular via its housing 28 is connected to the rotary drive. The torque converter 26 in turn is at a subsequent change gearbox 30 , here an automatic transmission, in particular at its input shaft 32 stored and thus can be applied to the output torque in this input shaft 32 initiate.

Der Drehmomentwandler 26 stellt somit ein zweites Übertragungselement, das Gangwechselgetriebe 30 eine zweite Funktionseinheit und die Getriebeeingangswelle 32 eine Drehachse B dar, um die sich der Drehmomentwandler 26 drehen kann. The torque converter 26 thus provides a second transmission element, the gear change transmission 30 a second functional unit and the transmission input shaft 32 a rotation axis B, around which the torque converter 26 can turn.

Zur gegenseitigen drehfesten Verbindung des Rotors 22 der elektrischen Maschine 14 mit dem Gehäuse 28 des Drehmomentwandlers 26 ist am radial äußeren Bereich des Rotors 22 ein Ringflansch 34 mit mehreren umfangsmäßig beabstandeten Gewindebohrungen 36 vorgesehen. Das Gehäuse 28 des Drehmomentwandlers 26 trägt eine radial von diesem abragende bzw. abstehende Ringscheibe 38 mit radial außen angeordneten Durchgangsöffnungen 40, durch welche Schraubbolzen 42 in die Gewindebohrungen 36 des Ringflansches 34 eingeführt und dort festgelegt werden können. Die Verbindung ist erkennbar als Schrägverschraubung ausgebildet, so dass dadurch ein Werkzeug durch eine im Gehäuse 44 des Gangwechselgetriebes 30 eingebrachte und in der 1 nicht dargestellte Öffnung leicht eingeführt werden kann. For mutual rotationally fixed connection of the rotor 22 the electric machine 14 with the housing 28 of the torque converter 26 is at the radially outer portion of the rotor 22 an annular flange 34 with a plurality of circumferentially spaced threaded holes 36 intended. The housing 28 of the torque converter 26 carries a radially projecting from this or projecting annular disc 38 with radially outwardly arranged passage openings 40 through which bolts 42 into the threaded holes 36 of the annular flange 34 introduced and can be specified there. The connection is recognizable as a diagonal screw, so that thereby a tool by a in the housing 44 the gear change transmission 30 introduced and in the 1 not shown opening can be easily inserted.

Der Flansch 34 des Rotors 22 bildet somit ein erstes Verbindungsmittel und die Ringscheibe 38 des Drehmomentwandlers 26 ein zweites Verbindungsmittel, wobei beide Verbindungsmittel und insbesondere ein gegenseitiger Verbindungsbereich radial außerhalb der jeweiligen Drehachsen A, B angeordnet sind bzw. ist. Zum Ausgleich von Montage- und/oder Fertigungstoleranzen können die Öffnungen 40 in der Ringscheibe 38 gegenüber den Schraubbolzen 42 etwas vergrößert ausgebildet sein. Zudem kann in dem vorliegenden Ausführungsbeispiel die Ringscheibe 38 innerhalb gewisser Grenzen radial flexibel ausgebildet sein. The flange 34 of the rotor 22 thus forms a first connection means and the annular disc 38 of the torque converter 26 a second connecting means, wherein both connecting means and in particular a mutual connection region are arranged radially outside of the respective axes of rotation A, B or is. To compensate for assembly and / or manufacturing tolerances, the openings 40 in the ring disk 38 opposite the bolts 42 be formed slightly enlarged. In addition, in the present embodiment, the annular disc 38 be formed radially flexible within certain limits.

Die bereits erwähnte Trennkupplung 16 ist hier als eine Reibungskupplung ausgebildet und umfasst eine in einem Innenraum des Stators 20 angeordnete Betätigungseinrichtung 46. Diese Betätigungseinrichtung 46 greift mittels eines hebelförmigen Betätigungsorgans 48 an einer axial verlagerbaren und durch Öffnungen im Rotorträger 24 ansteuerbaren Anpressplatte 50 an, welche eine an einer Zwischenwelle 52 angeordnete Kupplungsscheibe 54 gegenüber dem Ringflansch 34 reibschlüssig einklemmen oder freigeben kann. Die Zwischenwelle 52 wiederum steht mit der Kurbelwelle 56 des Verbrennungsmotors 12 in Wirkverbindung und bildet somit eine drehmomentübertragende Kupplungsnabe der Reibungskupplung 16 aus. The already mentioned separating clutch 16 is designed here as a friction clutch and includes one in an interior of the stator 20 arranged actuator 46 , This actuator 46 engages by means of a lever-shaped actuator 48 on an axially displaceable and through openings in the rotor carrier 24 controllable pressure plate 50 which one on an intermediate shaft 52 arranged clutch disc 54 opposite the annular flange 34 frictionally pinch or release. The intermediate shaft 52 in turn, stands with the crankshaft 56 of the internal combustion engine 12 in operative connection and thus forms a torque transmitting clutch hub of the friction clutch 16 out.

Wie weiter in 1 erkennbar, ist die Zwischenwelle 52 radial innerhalb des Rotorträgers 24 drehbar gelagert und durchdringt zudem den Rotor 22 in axialer Richtung. An dem getriebeseitigen Endbereich der Zwischenwelle 52 ist eine bezüglich der Drehachse A zentrale Lagerstelle 58 zur Aufnahme und Zentrierung eines dort eingreifenden Lagerzapfens 60 des Drehmomentwandlers 26 vorgesehen. Die Zwischenwelle 52 kann also in dieser Hinsicht als ein Lagerelement für den Drehmomentwandler 26, insbesondere für dessen Lagerzapfen 60 angesprochen werden. As in further 1 recognizable, is the intermediate shaft 52 radially inside the rotor carrier 24 rotatably mounted and also penetrates the rotor 22 in the axial direction. At the transmission end of the intermediate shaft 52 is a bearing point with respect to the axis of rotation A central 58 for receiving and centering a bearing pin engaging there 60 of the torque converter 26 intended. The intermediate shaft 52 So in this regard, as a bearing element for the torque converter 26 , in particular for its journal 60 be addressed.

In der vorliegenden idealisierten Darstellung fallen die Drehachsen A und B zusammen. Real tritt jedoch oftmals zwischen den Drehachsen A und B ein Versatz oder ein Schiefstand auf. Dieser kann dazu führen, dass beim Betreiben der Drehmomentübertragungsanordnung 10 im Bereich der Lagerstelle 58 eine unerwünschte Radialkraft eingebracht wird und dadurch insbesondere der Lagerzapfen 60 beschädigt werden kann. In the present idealized representation, the axes of rotation A and B coincide. Real, however, often occurs between the axes of rotation A and B, an offset or an obliquity. This can lead to when operating the torque transmission arrangement 10 in the area of the depository 58 an undesirable radial force is introduced and thereby in particular the bearing pin 60 can be damaged.

Zur Vermeidung dieses Effektes ist in die Lagerstelle 58 der Zwischenwelle 52 ein verschleißfähiges Zentrierelement 62 aus einem Kunststoff eingesetzt und dort form- und/oder kraftschlüssig festgelegt. Das Zentrierelement 62 weist mit Blick auf 2 einen hülsenförmigen Grundkörper 64 und mehrere davon, insbesondere nach radial innen abstehende Stege 66 auf, von welchen der Lagerzapfen 60 des Drehmomentwandlers 26 bei der Montage zentriert und im Betrieb getragen wird. Bei Einwirkung einer Radialkraft im Bereich der Lagerstelle 58 tritt an den Vorsprüngen bzw. Stegen 66 ein durch den Lagerzapfen 60 hervorgerufener Verschleiß auf, wodurch sich die Vorsprünge 66 radial verkürzen. Diese Verkürzung schreitet soweit voran bis sich der Lagerzapfen 60 im Wesentlichen radialkraftfrei in dem Zentrierelement 62 bewegen bzw. rotieren kann. To avoid this effect is in the bearing 58 the intermediate shaft 52 a wear-resistant centering element 62 used from a plastic and fixed there positive and / or non-positive. The centering element 62 points with a view 2 a sleeve-shaped body 64 and several thereof, in particular radially inwardly projecting webs 66 on which of the journal 60 of the torque converter 26 Centered during assembly and carried during operation. When exposed to a radial force in the area of the bearing 58 occurs at the projections or webs 66 a through the journal 60 caused wear on, causing the projections 66 shorten radially. This shortening progresses as far as the journal 60 essentially free of radial force in the centering element 62 can move or rotate.
