Description
Die Erfindung betrifft ein Hybridmodul für einen Antriebsstrang eines Kraftfahrzeuges, wie eines Pkws, Lkws, Busses oder sonstigen Nutzfahrzeuges, mit einem Gehäuse, einer von einer Umgebung in einen Innenraum des Gehäuses hineinragenden sowie in einer axialen Richtung und in einer radialen Richtung in Bezug auf eine Drehachse relativ zu dem Gehäuse abgestützten Eingangswelle, einem mit einem Rotor einer elektrischen Maschine rotatorisch gekoppelten Hauptträger und einer zwischen der Eingangswelle und dem Hauptträger wirkenden ersten Kupplung, sowie zwei jeweils mit dem Hauptträger wirkverbundenen zweiten und dritten Kupplungen. Des Weiteren betrifft die Erfindung einen Hybridantriebsstrang für ein (hybrides) Kraftfahrzeug, mit diesem Hybridmodul.The invention relates to a hybrid module for a drive train of a motor vehicle, such as a car, truck, bus or other commercial vehicle, comprising a housing, one of an environment in an interior of the housing and in an axial direction and in a radial direction with respect to a An axis of rotation relative to the housing supported input shaft, a rotatably coupled to a rotor of an electric machine main carrier and acting between the input shaft and the main carrier first clutch, and two each operatively connected to the main carrier second and third clutches. Furthermore, the invention relates to a hybrid powertrain for a (hybrid) motor vehicle, with this hybrid module.
Gattungsgemäßer Stand der Technik ist bereits hinlänglich bekannt. Die
Aus dem Stand der Technik sind folglich Hybridmodule bekannt, in denen eine seitens einer Verbrennungskraftmaschine eingesetzte erste Kupplung (auch als Trennkupplung bezeichnet) zusammen mit einer weiteren Kupplung oder zwei weiteren Kupplungen, die vorzugsweise eine Doppelkupplung ausbilden, eingesetzt sind. Im Betrieb werden durch Betätigung der ersten Kupplung in Kombination mit dem Betätigen der beiden weiteren Kupplungen verschiedene Anpresskräfte ausgeübt, die wiederum Gegenkräfte an dem Hauptträger bzw. dem Gehäuse sowie den Lagerstellen seitens des Gehäuses erzeugen. Eine ausreichend robuste Lagerung der Bestandteile des Hybridmoduls ist daher zu wählen. In ungünstigen Betriebspunkten können jedoch derart große und derart gerichtete Kräfte entstehen, die zu einer relativ großen Belastung der entsprechenden Bauteile und Lager führt. Auch sind die bekannten Lagerungen häufig relativ großbauend umgesetzt.Hybrid modules are therefore known from the prior art in which a first clutch (also referred to as a disconnect clutch) used by an internal combustion engine is used together with another clutch or two further clutches, which preferably form a dual clutch. In operation, by pressing the first clutch in combination with the actuation of the two other clutches different pressing forces are exerted, which in turn generate opposing forces on the main carrier and the housing and the bearings on the part of the housing. A sufficiently robust storage of the components of the hybrid module is therefore to be chosen. In unfavorable operating points, however, such large and directed forces can arise, which leads to a relatively large load on the corresponding components and bearings. Also, the known bearings are often implemented relatively large construction.
Es ist daher die Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik bekannten Nachteile zu beheben und insbesondere eine langlebige sowie kompakte Lagerung von Bestandteilen des Hybridmoduls zu erzielen.It is therefore the object of the present invention to eliminate the known from the prior art disadvantages and in particular to achieve a long-lived and compact storage of components of the hybrid module.
Dies wird erfindungsgemäß dadurch gelöst, dass die Eingangswelle über zumindest ein Radialnadellager und über zwei Axialnadellager relativ zu dem Gehäuse abgestützt ist.This is inventively achieved in that the input shaft is supported via at least one radial needle bearing and two axial needle bearing relative to the housing.
Dadurch ergibt sich einerseits eine besonders robuste Abstützung der Eingangswelle, andererseits ist die Lagerung der Eingangswelle relativ zu dem Gehäuse platzsparend ausgebildet. Durch das Radialnadellager ist die Lagerung in radialer Richtung besonders kompakt umgesetzt.On the one hand this results in a particularly robust support of the input shaft, on the other hand, the storage of the input shaft is designed to save space relative to the housing. Through the radial needle bearing storage in the radial direction is implemented very compact.
Weitere vorteilhafte Ausführungsformen sind mit den Unteransprüchen beansprucht und nachfolgend näher erläutert.Further advantageous embodiments are claimed with the subclaims and explained in more detail below.
Als besonders vorteilhaft hat es sich herausgestallt, wenn die Eingangswelle über zwei in der axialen Richtung relativ zueinander beabstandete Radialnadellager und über zwei in der axialen Richtung relativ zueinander beabstandete Axialnadellager relativ zu dem Gehäuse abgestützt ist. Dadurch ist die Eingangswelle noch robuster in radialer Richtung abgestützt.It has turned out to be particularly advantageous if the input shaft is supported relative to the housing via two radial needle bearings spaced apart in the axial direction relative to one another and via two axial needle bearings spaced apart relative to one another in the axial direction. As a result, the input shaft is supported even more robust in the radial direction.
Von Vorteil ist es auch, wenn die Eingangswelle einen zur drehfesten Aufnahme eines Drehschwingungsdämpfers ausgebildeten Verbindungsbereich (vorzugsweise als ein Verzahnungsbereich, weiter bevorzugt in Form einer Kerbverzahnung, ausgebildet) aufweist und ein den Innenraum zu der Umgebung hin abdichtender Dichtring radial außerhalb dieses Verbindungsbereiches angeordnet ist. Weiter bevorzugt ist der Dichtring in axialer Richtung auf Höhe eines Längsabschnittes des Verbindungsbereiches angeordnet. Dadurch wird weiterer Bauraum in axialer Richtung eingespart.It is also advantageous if the input shaft has a connection region (preferably designed as a toothed region, more preferably in the form of a serration) for the rotationally fixed reception of a torsional vibration damper and a sealing ring sealing the interior to the environment is arranged radially outside this connection region. More preferably, the sealing ring is arranged in the axial direction at the height of a longitudinal portion of the connecting region. This saves additional space in the axial direction.
Das Radialnadellager sowie die beiden Axialnadellager sind vorzugsweise zu einer dem Innenraum zugewandten axialen Seite des Dichtrings angeordnet. Dadurch werden diese Lager im Betrieb verlässlich vor äußeren Einflüssen geschützt. Da die Kupplungen jeweils vorzugsweise nass laufend ausgebildet sind, findet auch eine Schmierung dieser Lager besonders effektiv im Betrieb statt.The radial needle bearing and the two axial needle bearings are preferably arranged to an inner side facing the axial side of the sealing ring. As a result, these bearings are reliably protected against external influences during operation. Since the couplings are each preferably designed to be wet-running, lubrication of these bearings also takes place particularly effectively during operation.
Zweckmäßig ist es weiterhin, wenn zwei die Eingangswelle radial zu dem Gehäuse lagernde Radialnadellager in der axialen Richtung zwischen den beiden die Eingangswelle axial zu dem Gehäuse lagernden Axialnadellager angeordnet sind. Dadurch wird der Herstellaufwand der Lagerstelle weiter reduziert.It is also expedient if two radial needle bearings supporting the input shaft radially to the housing are arranged in the axial direction between the two axial needle bearings axially supporting the input shaft. As a result, the manufacturing cost of the bearing is further reduced.
Alternativ hierzu ist es auch von Vorteil, wenn in der axialen Richtung zwischen einem die Eingangswelle radial zum Gehäuse lagernden ersten Radialnadellager und einem die Eingangswelle radial zum Gehäuse lagernden zweiten Radialnadellager ein die Eingangswelle axial zum Gehäuse lagerndes erstes Axialnadellager angeordnet ist. Dadurch ergibt sich eine besonders geschickte Aufteilung der Lagerkräfte im Betrieb.Alternatively, it is also advantageous if in the axial direction between a first radial needle bearing radially supporting the input shaft to the housing and a second radial needle bearing radially supporting the input shaft, a first axial needle bearing axially supporting the input shaft is arranged. This results in a particularly clever division of the bearing forces during operation.
Besonders bevorzugt sind die Axialnadellager in radialer Richtung gesehen auf gleicher Höhe angeordnet, weiter bevorzugt auf unterschiedlichen Höhen angeordnet. Weiter bevorzugt sind die Radialnadellager (bei Vorsehen zweier Radialnadellager) in radialer Richtung gesehen (relativ zueinander) auf gleicher Höhe angeordnet, weiter bevorzugt auf unterschiedlichen Höhen angeordnet.Particularly preferred are the axial needle bearings seen in the radial direction at the same height arranged, more preferably arranged at different heights. More preferably, the radial needle bearings are (when providing two radial needle bearings) seen in the radial direction (relative to each other) arranged at the same height, more preferably arranged at different heights.
Des Weiteren ist es vorteilhaft, wenn ein die Eingangswelle axial zu dem Gehäuse lagerndes zweites Axialnadellager auf einer dem ersten Axialnadellager axial abgewandten Seite (des ersten Radialnadellagers oder besonders bevorzugt) des zweiten Radialnadellagers angeordnet ist.Furthermore, it is advantageous if a second axial needle bearing axially supporting the input shaft is arranged on a side facing away from the first axial needle bearing (of the first radial needle bearing or particularly preferably) of the second radial needle bearing.
Ist eines der beiden die Eingangswelle axial zu dem Gehäuse lagernden Axialnadellager mittels einer Feder, vorzugsweise einer Wellenfeder, vorgespannt, wird ein axiales Spiel der Lager auf einfache Weise deutlich reduziert. Insbesondere ist es bevorzugt, das zweite Axialnadellager mit einer solchen Feder unmittelbar vorzuspannen.If one of the two axial needle bearings supporting the input shaft axially to the housing is pretensioned by means of a spring, preferably a wave spring, an axial play of the bearings is clearly reduced in a simple manner. In particular, it is preferable to directly bias the second thrust needle bearing with such a spring.
Dabei hat es sich zudem als zweckmäßig herausgestellt, wenn die Feder axial zwischen einem gehäusefesten Bereich und dem Axialnadellager, d.h. einem entsprechenden Lagerring des Axialnadellagers, eingespannt ist. Dadurch wird die Feder besonders kompakt ausgebildet.In addition, it has been found to be expedient if the spring extends axially between a housing-fixed area and the axial needle bearing, i. a corresponding bearing ring of the Axialnadellagers, is clamped. As a result, the spring is designed to be particularly compact.
Sind / ist das zumindest eine die Eingangswelle radial zu dem Gehäuse lagernde Radialnadellager und/oder eines der beiden die Eingangswelle axial zu dem Gehäuse lagernden Axialnadellager zwischen einem an der Eingangswelle befestigten Wellenaufsatz und dem Gehäuse angeordnet, wird der Montageaufwand weiter reduziert.Are / is at least one of the input shaft radially to the housing overlapping radial needle bearing and / or one of the two axially supporting the input shaft to the housing mounted Axialnadelellager between a shaft attached to the input shaft attachment and the housing, the assembly cost is further reduced.
In diesem Zusammenhang ist es auch vorteilhaft, wenn der Dichtring an dem Wellenaufsatz aufgenommen ist.In this context, it is also advantageous if the sealing ring is received on the shaft attachment.
