Abstract

The clutch (1) has a disc pack (11) arranged at inner and outer plate carriers (1A, 1B) and including inner and outer plates (2, 3). An actuating piston (4) is prestressed in a disengagement direction and is actuated in an engagement direction for compression of the plates. The piston includes a cooling oil supply bore (8) for feeding cooling oil into an outer clutch chamber (9) of clutch housing (12), where the outer chamber accommodates the disc pack. The supply bore connects the outer clutch chamber with a radial inwardly lying bore (7).

Description

Die Erfindung betrifft eine Lamellenkupplung gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a multi-plate clutch according to the Preamble of claim 1.

Eine gattungsgemäße Lamellenkupplung ist aus der DE 199 37 440 C1 bekannt.A generic multi-plate clutch is from the DE 199 37 440 C1 known.

Es ist demgegenüber Aufgabe der vorliegenden Erfindung, eine Lamellenkupplung der im Oberbegriff des Anspruchs 1 angegebenen Art zu schaffen, die eine Zwangsdurchströmung des Lamellenpaketes mit Kühlöl ermöglicht.It is the object of the present invention, a Multi-plate clutch specified in the preamble of claim 1 To create a type, the forced flow of the disk pack with cooling oil allows.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruchs 1.The This object is achieved by the features of the claim 1.

Die Unteransprüche haben eine vorteilhafte Weiterbildung der Erfindung zum Inhalt.The Dependent claims have an advantageous development of Invention to the content.

Insbesondere ist es durch das Vorsehen einer radialen Durchgangsbohrung im Kolben der erfindungsgemäßen Kupplung möglich, einen Kühlölstrom von einer inneren Zuleitung in einen Außenbereich des Kupplungsraumes zu befördern, in dem sich das Lamellenpaket befindet. Bei angelegtem Kolben ist es daher möglich, dass Kühlöl radial von außen nach innen durch das Lamellenpaket zu befördern, so dass eine Zwangsdurchströmung des Lamellenpaketes ermöglicht wird.Especially it is by providing a radial through bore in the piston the coupling according to the invention possible, a cooling oil flow from an inner supply line to convey into an outside area of the coupling space, in which the disk pack is located. When the piston is applied It is therefore possible that cooling oil radially from the outside to the inside through the disk pack, so that a forced flow of the disk pack allows becomes.

Diese Konstruktion ist insofern vorteilhaft, als sie einfach aufgebaut ist und eine erhebliche Verbesserung der Kühlwirkung möglich macht.These Construction is advantageous in that it is simple in construction is and a significant improvement in the cooling effect possible power.

Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich aus nachfolgender Beschreibung eines Ausführungsbeispiels anhand der Zeichnung.Further Details, advantages and features of the invention will become apparent following description of an embodiment based the drawing.

Die einzige Figur der Zeichnung zeigt eine erfindungsgemäße Lamellenkupplung 1, in deren Gehäuse 12 ein Lamellenpaket 11 angeordnet ist. Das Lamellenpaket 11 weist einen Innenlamellenträger 1A für Innenlamellen 2 und einen Außenlamellenträger 1B für Außenlamellen 3 auf.The sole figure of the drawing shows a multi-plate clutch according to the invention 1 in their case 12 a disc pack 11 is arranged. The slat package 11 has an inner disk carrier 1A for inner plates 2 and an outer disc carrier 1B for outer plates 3 on.

Ferner ist im Gehäuse 12 ein durch Öldruck verschiebbarer Betätigungskolben 4 zum Zusammendrücken der Innen- und Außenlamellen 2 und 3 vorgesehen, der durch eine Federanordnung 13 in Ausrückrichtung vorgespannt ist.Furthermore, in the housing 12 a displaceable by oil pressure actuating piston 4 for compressing the inner and outer disks 2 and 3 provided by a spring arrangement 13 is biased in the release direction.

Der Kolben 4 teilt den Innenraum des Gehäuses 12 in einen äußeren Kupplungsraum 9 und einen Ölzuführbereich auf, der im Beispielsfalle durch eine radial innenliegende Bohrung 7 gebildet wird, die wiederum mit einer hohlen Welle 5 zur Kühlölzuführung verbunden ist.The piston 4 divides the interior of the case 12 in an outer clutch room 9 and an oil feed area, which in the exemplary case by a radially inner bore 7 is formed, in turn, with a hollow shaft 5 connected to the cooling oil supply.

Ferner steht eine Ölzuführöffnung 6 mit der Welle 5 in Strömungsverbindung, die zur Zuführung von Drucköl dient, um den Kolben 4 entgegen der Vorspannkraft der Feder 13 zum Einrücken der Kupplung zu verschieben.Furthermore, there is an oil feed opening 6 with the wave 5 in fluid communication, which serves to supply pressurized oil to the piston 4 against the biasing force of the spring 13 to move to engage the clutch.

Wie die Figur verdeutlicht, ist im Kolben 4 eine radial von der Innenseite zur Außenseite des Gehäuses 12 verlaufende Kühlölzuführbohrung 8 vorgesehen, die die Zuführöffnung 7 mit dem Außenraum 9 verbindet, so dass bei eingerücktem Kolben 4 die eingangs erläuterte Zwangsdurchströmung des Lamellenpaketes 11 von außen nach innen in einen Innenraumbereich 10 der Kupplung 1 möglich macht. Vom Innenraum 10 kann das Kühlöl in die Welle 5 zurückgeführt werden.As the figure illustrates, is in the piston 4 a radially from the inside to the outside of the housing 12 running cooling oil supply hole 8th provided that the feed opening 7 with the outside space 9 connects, so with the piston engaged 4 the initially described forced flow of the disk pack 11 from outside to inside in an interior area 10 the clutch 1 makes possible. From the interior 10 can the cooling oil in the shaft 5 to be led back.

Zur Ergänzung der schriftlichen Offenbarung wird auf deren zeichnerische Darstellung in der Figur der Zeichnung explizit verwiesen.to Supplementing the written revelation will be on their Drawings explicitly referenced in the figure of the drawing.
