Es ist an sich bekannt, dass Wälzlager und Wellendichtringe generell mit einer ausreichenden Ölschmierung versehen sein sollten. In der Praxis werden bei der vorerwähnten Doppelkupplung das in Rede stehende Wälzlager und der Wellendichtring aufwendig von Innen durch die Welle beölt, wobei das Schmieröl mit recht hohem Aufwand in die Welle gedrückt werden muss. Hier setzt die nachfolgend beschriebene Erfindung an.It is known per se, that rolling bearings and shaft seals generally with sufficient oil lubrication should be provided. In practice, in the aforementioned double clutch the bearing in question and the shaft seal consuming oiled from inside through the shaft, the oil must be pressed into the shaft with quite a lot of effort. Here sets the invention described below.

von der gattungsbildenden
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Hauptanspruchs, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnehmbar sind.The solution This object is apparent from the features of the main claim, while advantageous embodiments and developments of the invention the dependent claims are removable.
Demnach geht die Erfindung zunächst aus von einem Ölschmiersystem für eine mit einem Gangschaltgetriebe wirkverbundene Mehrfachkupplung, mit zumindest einer ersten Getriebeeingangswelle zum Antrieb einer ersten Gruppe von Getriebegängen und einer zweiten Getriebeeingangswelle zum Antrieb einer zweiten Gruppe von Getriebegängen, wobei den Getriebeeingangswellen je eine Kupplungseinheit zugeordnet ist, sowie mit einem die Kupplungseinheiten aufnehmenden Kupplungskorb, der in einem stationären Gehäuse drehgelagert ist, wobei das Gehäuse stirnseitig durch einen fest mit demselben ver bindbaren Gehäusedeckel verschließbar ist, welcher eine zentrale Öffnung aufweist, durch die eine Antriebsnabe des Kupplungskorbes hindurchgeführt ist, welche über wenigstens ein Wälzlager am Gehäusedeckel abgestützt ist, und wobei zwischen dem Gehäusedeckel und der Antriebsnabe zumindest ein Wellendichtring angeordnet ist.Accordingly, the invention is initially based on an oil lubrication system for a multiple clutch operatively connected to a gearshift transmission, with at least one first transmission input shaft for driving a first group of transmission gears and a second transmission input shaft for driving a second group of transmission gears, wherein the transmission input shafts are each assigned a clutch unit, and with a coupling basket receiving the coupling units, which is rotatably mounted in a stationary housing, wherein the housing is frontally closed by a fixed ver bindable housing cover, which has a central opening through which a drive hub of the clutch basket is passed, which is supported via at least one roller bearing on the housing cover, and wherein between the housing cover and the drive hub at least one Shaft seal is arranged.
Die gestellte Aufgabe ist dadurch gelöst, dass in einer zwischen Gehäusedeckel und Kupplungskorb vorgesehenen axialen Beabstandung am Gehäusedeckel zumindest ein weitestgehend radial ausgerichtetes Sammel- und Leitblech zur gezielten Weiterleitung von aus den Kupplungseinheiten beziehungsweise aus dem Kupplungskorb herausgeschleudertem Schmieröl zum Wälzlager und weiter durch dasselbe hindurch zum Wellendichtring festgelegt ist.The Asked task is solved in that in between housing cover and clutch basket provided axial spacing on the housing cover at least a largely radially aligned collection and baffle for the targeted forwarding of the coupling units or from the clutch basket ejected lubricating oil to the rolling bearing and fixed further therethrough to the shaft seal is.
Durch diese Maßnahme ist eine besonders einfache und kostengünstige Konstruktion zur Schmierung des in Rede stehenden Wälzlagers sowie des Wellendichtrings geschaffen, die obendrein im Vergleich mit herkömmlichen Lösungen noch gewichtsoptimiert ist.By This measure is a particularly simple and inexpensive construction for lubrication of the rolling bearing in question as well as the shaft seal created, the plus in comparison with conventional solutions is still weight optimized.
In Weiterbildung der Erfindung kann das Sammel- und Leitblech nach radial innen leicht trichterförmig ausgebildet sein. Weiter wird vorgeschlagen, dass das Sammel- und Leitblech in Umfangsrichtung gesehen gewellt ausgebildet ist, wobei die gebildeten Wellenkonturen von radial innen nach radial außen strahlenförmig ausgerichtet sind.In Development of the invention, the collecting and baffle after radially inside slightly funnel-shaped be educated. It is also proposed that the collection and Guide plate seen in the circumferential direction is formed corrugated, wherein the formed wave contours are radially aligned radially inward to radially outward are.
Als zweckmäßig hat sich erwiesen, dass das Sammel- und Leitblech radial außen einen abgestellten und über den Kupplungskorb reichenden Flansch aufweist.When has appropriate proved that the collecting and baffle radially outward one parked and over Having the clutch basket reaching flange.
Ebenso ist es denkbar, dem Sammel- und Leitblech ein separates, fest am Gehäusedeckel oder einem anderen geeigneten drehfesten Bauteil angeordnetes weiteres Leitblech mit einem radial außen über den Kupplungskorb reichenden Flansch zuzuordnen.As well It is conceivable, the collecting and baffle a separate, firmly on housing cover or another suitable non-rotatable component arranged further Baffle with a radially outside over the Assemble clutch basket reaching flange.
Wie die Erfindung weiter vorsieht, ist radial innen in einem Bereich zwischen dem Wälzlager und der Antriebsnabe eine Kammer und/oder in der Antriebsnabe eine Ringnut zum Sammeln von Schmieröl vorgesehen, welche an zumindest eine Ölabflussbohrung in der Antriebsnabe angeschlossen sind. In vorteilhafter Weise verbindet die zumindest eine Ölabflussbohrung die Kammer und/oder Ringnut mit wenigstens einer der Getriebeeingangswellen und/oder mit einer Lagerung derselben.As the invention further provides, is radially inward in a range between the rolling bearing and the drive hub a chamber and / or in the drive hub a Ring groove for collecting lubricating oil provided, which at least one oil drain hole in the drive hub are connected. In an advantageous manner, the at least connects an oil drain hole the chamber and / or annular groove with at least one of the transmission input shafts and / or with a storage of the same.
Gemäß einer anderen bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass sich das Sammel- und Leitblech lediglich über denjenigen oberen Teilkreis des Gehäusedeckels erstreckt, welcher in einer Einbausituation ein schwerkraftbedingtes Ablaufen des Schmieröls zu dem Wälzlager und dem Wellendichtring ermöglicht.According to one Another preferred embodiment of the invention is provided, that the collecting and baffle plate only on those upper pitch circle of the housing cover extends, which in a mounting situation, a gravitational Drain the lubricating oil to the rolling bearing and the shaft seal allows.
Die erfindungsgemäße Lösung bietet sich insbesondere zur Verwendung an einer Doppelkupplung eines Doppelkupplungsgetriebes an.The inventive solution offers in particular for use on a dual clutch of a dual clutch transmission at.
Zur Verdeutlichung der Erfindung ist der Beschreibung eine Zeichnung beigefügt.to Clarification of the invention, the description is a drawing attached.
