Description
Die Erfindung betrifft die Lagerung in einem Hybridantriebsmodul für ein Kraftfahrzeug, wobei das Hybridmodul zwischen einem Verbrennungsmotor und einem Getriebe angeordnet ist und eine elektrische Maschine aufweist.The invention relates to the storage in a hybrid drive module for a motor vehicle, wherein the hybrid module is arranged between an internal combustion engine and a transmission and has an electrical machine.
Im Stand der Technik sind verschiedene Bauformen von Hybridmodulen bekannt. Hierbei sind die bewegten Teile wie Eingangswelle oder Rotorträger am ruhenden Gehäuse abgestützt. Beispielsweise sind in
Nachteilig am Stand der Technik ist der benötigte Bauraum, die aufwendige Gehäusefertigung sowie insbesondere der Montageaufwand, da aufgrund der Kugellager hohe Montagekräfte auftreten, welche durch magnetische Kräfte in der elektrischen Maschine erhöht werden.Various types of hybrid modules are known in the prior art. Here, the moving parts such as input shaft or rotor carrier are supported on the stationary housing. For example, in
A disadvantage of the prior art is the required installation space, the complex housing production and in particular the assembly effort, since due to the ball bearings high assembly forces occur, which are increased by magnetic forces in the electric machine.
Aufgabe der Erfindung ist es daher ein Hybridmodul bereitzustellen, welches eine zuverlässige Lagerung aufweist sowie einfach herzustellen und zu montieren ist.The object of the invention is therefore to provide a hybrid module, which has a reliable storage and is easy to manufacture and assemble.
Die Aufgabe wird gelöst durch die Merkmale des unabhängigen Patentanspruchs. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen, der Beschreibung sowie aus den Figuren.The object is solved by the features of the independent claim. Advantageous embodiments will become apparent from the dependent claims, the description and from the figures.
Erfindungsgemäß ist ein Hybridmodul umfassend eine Eingangswelle, welche mit einem Verbrennungsmotor verbunden ist, ein Gehäuse, eine Kupplung, eine elektrische Maschine, welche einen Rotor und einen mit dem Gehäuse verbundenen Stator aufweist, einen Drehmomentwandler, welcher ein mit einer Zentralnabe verbundenes Wandlergehäuse und eine Turbinennabe aufweist, und eine Abtriebswelle, wobei der Rotor der elektrischen Maschine mit der Zentralnabe oder dem Wandlergehäuse verbunden ist, wobei die Turbinennabe drehfest mit der Abtriebswelle verbunden ist, und wobei die Kupplung zwischen der Eingangswelle und dem Drehmomentwandler angeordnet ist, dadurch gekennzeichnet, dass Drehmomentwandler, Rotor, Kupplung und Eingangswelle gemeinsam in axialer Richtung gelagert sind, dass die gemeinsame axiale Lagerung über ein erstes Axiallager und ein zweites Axiallager erfolgt, und dass das erste Axiallager durch ein erstes Federelement oder das zweite Axiallager durch ein zweites Federelement in axialer Richtung beweglich ausgeführt sowie mit einer Vorlast beaufschlagt ist.According to the invention, a hybrid module comprising an input shaft connected to an internal combustion engine, a housing, a clutch, an electric machine having a rotor and a stator connected to the housing, a torque converter having a converter housing connected to a central hub and a turbine hub and an output shaft, wherein the rotor of the electric machine is connected to the central hub or the converter housing, wherein the turbine hub is non-rotatably connected to the output shaft, and wherein the clutch between the input shaft and the torque converter is arranged, characterized in that torque converter, Rotor, clutch and input shaft are mounted together in the axial direction, that the common axial bearing via a first thrust bearing and a second thrust bearing, and that the first thrust bearing by a first spring element or the second thrust bearing by a second spring element designed to be movable in the axial direction and acted upon by a preload.
Bei einem Hybridmodul werden zwei unterschiedliche Antriebsquellen für eine Anwendung verwendet, wobei diese alternativ oder kumulativ betrieben werden können. Eine verbreitete Kombination ist ein Verbrennungsmotor und eine elektrische Maschine. Das Hybridmodul führt hierbei den oder die Kraftflüsse an den folgenden Verbraucher, wie beispielsweise einem Antriebsstrang eines Fahrzeugs, weiter.In a hybrid module, two different drive sources are used for an application, which can be operated alternatively or cumulatively. A common combination is an internal combustion engine and an electric machine. The hybrid module in this case leads the one or more power flows to the following consumer, such as a drive train of a vehicle on.
Um eine Krafteinleitung vom Verbrennungsmotor zu ermöglichen, weist das Hybridmodul eine Eingangswelle auf, welche mit dem Verbrennungsmotor verbunden ist. Durch die Eingangswelle kann eine Drehbewegung an eine Kupplung weitergegeben werden. Die Kupplung hat die Aufgabe, den Verbrennungsmotor vom Antriebsstrang abzukoppeln, wenn der Verbrennungsmotor abgeschalten ist, um Verluste zu vermeiden.In order to enable an introduction of force from the internal combustion engine, the hybrid module has an input shaft, which is connected to the internal combustion engine. Through the input shaft, a rotary motion can be passed to a clutch. The clutch has the task of decoupling the engine from the drive train when the engine is turned off to avoid losses.
Die Kupplung ist ebenso wie eine elektrische Maschine in einem Gehäuse angeordnet, wobei der Stator der elektrischen Maschine mit dem Gehäuse verbunden ist. Der Rotor der elektrischen Maschine ist als weitere Antriebsquelle im Kraftfluss nach der Kupplung angeordnet und mit der Eingangsseite eines Drehmomentwandlers verbunden. Die Verbindung mit dem Drehmomentwandler erfolgt über das Wandlergehäuse und der Rotor kann entweder direkt mit diesem verbunden oder an einer mit diesem verbundenen Zentralnabe vorgesehen werden, wobei auch Ausführungsformen eingeschlossen sind, bei denen der Rotor über einen Rotorträger mit der Zentralnabe oder dem Wandlergehäuse verbunden ist.The clutch is as well as an electric machine arranged in a housing, wherein the stator of the electric machine is connected to the housing. The rotor of the electric machine is arranged as a further drive source in the power flow after the clutch and connected to the input side of a torque converter. The connection with the torque converter via the converter housing and the rotor can either be connected directly to this or provided on a central hub connected to this, including embodiments are included, in which the rotor is connected via a rotor carrier with the central hub or the converter housing.
Die Ausgangsseite des Drehmomentwandlers wird von einer Turbinennabe gebildet, welche mit der Abtriebswelle drehfest verbunden ist. Über die Abtriebswelle ist das Hybridmodul mit dem weiteren Antriebsstrang, wie einem Getriebe, insbesondere einem Automatikgetriebe, verbunden.The output side of the torque converter is formed by a turbine hub, which is rotatably connected to the output shaft. About the output shaft, the hybrid module with the other drive train, such as a transmission, in particular an automatic transmission connected.
Eine Lagerung für Drehmomentwandler, Rotor, Kupplung und Eingangswelle erfolgt in axialer Richtung gemeinsam über ein erstes Axiallager und ein zweites Axiallager. Gegenüber einer jeweils einzelnen Lagerung der Bauteile, kann so die Teilezahl verringert sowie Bauraum eingespart werden. Aufgrund von Fertigungstoleranzen kann die axiale Erstreckung der einzelnen Bauteile in einem gewissen Bereich liegen, wobei sich diese Abweichungen vom Sollmaß durch den Zusammenbau ausgleichen oder aber auch aufsummieren können. Zumindest das erste Axiallager oder das zweite Axiallager ist daher durch ein erstes Federelement beziehungsweise durch ein zweites Federelement in axialer Richtung beweglich ausgeführt, wobei das erste oder zweite Federelement beispielsweise als Tellerfeder, Wellenfeder, Spiralfeder oder Elastomerblock ausgeführt sein kann und zwischen Axiallager und Gehäuse und/oder zwischen Axiallager und zu lagerndem Bauteil angeordnet ist. Neben dem Toleranzausgleich ist gleichzeitig die axiale Lagerung durch das zumindest eine Federelement mit einer Vorlast beaufschlagt, wodurch die Axiallager sicher positioniert sind und ein Abheben, zum Beispiel durch während des Betriebs auftretende Kräfte vermieden wird.A bearing for torque converter, rotor, clutch and input shaft takes place in the axial direction together via a first thrust bearing and a second thrust bearing. Compared to each individual storage of components, so the number of parts can be reduced and space can be saved. Due to manufacturing tolerances, the axial extent of the individual components can be within a certain range, whereby these deviations from the nominal dimension can be compensated by the assembly or else can add up. At least the first thrust bearing or the second thrust bearing is therefore designed to be movable in the axial direction by a first spring element or by a second spring element, wherein the first or second spring element may be designed as a plate spring, wave spring, coil spring or elastomer block and between thrust bearing and housing and / or or between thrust bearing and to be stored component is arranged. In addition to the tolerance compensation is at the same time the axial bearing is acted upon by the at least one spring element with a preload, whereby the thrust bearings are securely positioned and lifting, for example, by forces occurring during operation is avoided.
Neben reinen Axiallagern sind auch Ausführungsformen möglich, bei denen das erste und/oder das zweite Axiallager auch Lagerkräfte in anderen Richtungen aufnehmen kann, wie beispielsweise Schrägkugellager, Rillenkugellager, Kegelrollenlager oder dergleichen. Hierdurch kann eventuell die Anzahl der Bauteile verringert werden. Im Falle von Wälzlagern, die beidseitige Axialkräfte aufnehmen können, kann das erste und zweite Axiallager auch durch ein einzelnes Lager erfolgen.In addition to pure thrust bearings and embodiments are possible in which the first and / or the second thrust bearing can also absorb bearing forces in other directions, such as angular contact ball bearings, deep groove ball bearings, tapered roller bearings or the like. This may possibly reduce the number of components. In the case of rolling bearings that can accommodate bilateral axial forces, the first and second thrust bearing can also be done by a single bearing.
Ausführungsformen eines Hybridmoduls sind dadurch gekennzeichnet, dass das erste Axiallager durch ein erstes Federelement und das zweite Axiallager durch ein zweites Federelement in axialer Richtung beweglich ausgeführt sowie mit einer Vorlast beaufschlagt sind. Durch Ausführungsformen, bei denen beide Axiallager durch Federelemente abgestützt sind, lässt sich einfach ein benötigter Federweg erreichen, da dieser entsprechend auf die beiden Federelemente aufgeteilt wird. Gleichzeitig können die Bauteile im Gehäuse hierdurch besser zentriert werden und es wird eine gewisse Dämpfung von plötzlich auftretenden Kräften während des Betriebs in beide axiale Richtungen erzielt.Embodiments of a hybrid module are characterized in that the first thrust bearing are designed to be movable in the axial direction by a first spring element and the second thrust bearing by a second spring element and are subjected to a preload. By embodiments in which both thrust bearings are supported by spring elements, it is easy to achieve a required spring travel, since this is divided according to the two spring elements. At the same time, the components in the housing can thereby be better centered and it is achieved a certain damping of sudden forces during operation in both axial directions.
Hybridmodule gemäß Ausführungsformen sind dadurch gekennzeichnet, dass ein drittes Axiallager zwischen Eingangswelle und Zentralnabe vorgesehen ist. Im Kraftfluss entlang der gemeinsam gelagerten Bauteile ist auch die Kupplung vorhanden. Bei geschlossener Kupplung können hierüber auch axiale Kräfte übertragen werden. Um jedoch axiale Kräfte auch bei geöffneter Kupplung, vorzugsweise unabhängig von der Kupplungsbetätigung, übertragen zu können, wird zwischen mit der Eingangsseite beziehungsweise der Ausgangsseite verbundene Bauteile, insbesondere der Eingangswelle und der Zentralnabe, ein drittes Axiallager vorgesehen. Prinzipiell können die Bauteile auch direkt aneinander liegen, was jedoch zu einem erhöhten Verschleiß bedingt durch die während des Betriebs, genauer bei getrennter Kupplung oder während der Betätigung, auftretenden Relativbewegung führen würde.Hybrid modules according to embodiments are characterized in that a third thrust bearing is provided between the input shaft and the central hub. In the power flow along the jointly stored components and the coupling is present. When the clutch is closed, axial forces can also be transmitted. However, in order to be able to transmit axial forces even when the clutch is open, preferably independently of the clutch actuation, a third thrust bearing is provided between components connected to the input side or the output side, in particular the input shaft and the central hub. In principle, the components can also lie directly against one another, which would, however, lead to increased wear due to the relative movement occurring during operation, more precisely in the case of separate coupling or during actuation.
Ausführungsformen eines Hybridmoduls sind dadurch gekennzeichnet, dass das erste Axiallager zwischen dem Wandlergehäuse und dem Gehäuse angeordnet ist. Für eine möglichst breite Lagerbasis und die Vermeidung von Zugspannungen in den Bauteilen ist das erste Axiallager zwischen Wandlergehäuse und Gehäuse angeordnet, vorzugweise auf der dem im Antriebsstrang folgenden Getriebe zugewandten Seite.Embodiments of a hybrid module are characterized in that the first thrust bearing is arranged between the converter housing and the housing. For a broadest possible bearing base and the avoidance of tensile stresses in the components, the first thrust bearing between the converter housing and housing is arranged, preferably on the side facing the drive train in the transmission side.
Ausführungsformen eines Hybridmoduls sind dadurch gekennzeichnet, dass das zweite Axiallager zwischen der Eingangswelle und dem Gehäuse angeordnet ist. Wie bereits erwähnt, wird hierdurch eine große Lagerbasis erzielt und Zugkräfte vermieden. Weiter wird hierdurch das zweite Axiallager als eines der letzten Bauteile montiert, weshalb gegebenenfalls noch leicht Anpassungen vorgenommen werden können, um beispielsweise ein zweites Federelement entsprechend der tatsächlich benötigten Vorlast beziehungsweise benötigten Federweg aufgrund der aufsummierten Toleranzen in axialer Richtung auszuwählen.Embodiments of a hybrid module are characterized in that the second thrust bearing is arranged between the input shaft and the housing. As already mentioned, this achieves a large bearing base and avoids tensile forces. Furthermore, as a result, the second thrust bearing is mounted as one of the last components, which is why slight adjustments can still be made, for example, to select a second spring element according to the actually required preload or required travel due to the summed tolerances in the axial direction.
Hybridmodule gemäß Ausführungsformen sind dadurch gekennzeichnet, dass die Axiallager als axiale Wälzlager ausgebildet sind. Hierbei können insbesondere AxialKugellager, Axial-Zylinderrollenlager oder Axial-Pendelkugellager verwendet werden.Hybrid modules according to embodiments are characterized in that the thrust bearings are designed as axial rolling bearings. In particular, axial ball bearings, axial cylindrical roller bearings or axial spherical roller bearings can be used.
Ausführungsformen eines Hybridmoduls sind dadurch gekennzeichnet, dass für eine Lagerung in radialer Richtung mindestens ein Radiallager vorgesehen ist. Neben axialen Kräften treten auch radiale Kräfte auf, welche über entsprechende Radiallager aufgenommen werden. Die Radiallager sind insbesondere zwischen Eingangswelle und Gehäuse und/oder Wandlergehäuse und Gehäuse angeordnet. Bevorzugt im Bereich der Axiallager, um einen breite Lagerbasis sowie einen gleichmäßigen Kraftfluss zu erreichen.Embodiments of a hybrid module are characterized in that for storage in the radial direction at least one radial bearing is provided. In addition to axial forces, radial forces also occur which are absorbed by corresponding radial bearings. The radial bearings are arranged in particular between the input shaft and housing and / or converter housing and housing. Preferably in the area of the thrust bearings in order to achieve a broad bearing base and a uniform flow of force.
Bevorzugte Ausführungsformen eines Hybridmodul sind dadurch gekennzeichnet, dass das mindestens eine Radiallager als Nadellager oder Rollenlager ausgeführt ist. Da Axialkräfte durch die Axiallager aufgenommen werden, bieten sich für die Radiallager insbesondere Nadellager und Rollenlager an, wodurch die Radialkräfte bei relativ kleinem Bauraum effektiv aufgenommen werden können.
Aufgrund der federbelasteten Lagerung über die beiden Axiallager können die Radiallager mit Lagerluft vorgesehen werden, wodurch die Montage vereinfacht wird und der Kraftverlust verringert werden kann.Preferred embodiments of a hybrid module are characterized in that the at least one radial bearing is designed as a needle bearing or roller bearing. Since axial forces are absorbed by the thrust bearings, needle roller bearings and roller bearings are particularly suitable for the radial bearings, as a result of which the radial forces can be effectively absorbed in a relatively small installation space.
Due to the spring-loaded bearing over the two thrust bearings, the radial bearings can be provided with bearing clearance, whereby the assembly is simplified and the loss of power can be reduced.
