Description

Die vorliegende Erfindung bezieht sich auf einen topfförmigen Lamellenträger eines Lamellenschaltelementes eines Getriebes eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a cup-shaped plate carrier of a plate switching element of a transmission of a motor vehicle according to the preamble of patent claim 1.

Aus dem Stand der Technik ist bekannt, die topfförmigen Lamellenträger von Lamellenkupplungen im Nabenbereich mit Bohrungen zu versehen, durch die das Öl auch bei einer Drehbewegung des Lamellenträgers vom Füllausgleichsraum zu den Kupplungslamellen gelangen soll.From the prior art it is known to provide the pot-shaped plate carrier of multi-plate clutches in the hub area with holes through which the oil should pass from the Füllausgleichsraum to the clutch plates even with a rotational movement of the disc carrier.

Beispielsweise ist aus der DE 10 2010 039 171 A1 bekannt, die Bohrungen in Bezug auf den Nabenbereich achsparallel zur Lamellenträgerlängsachse auszuführen. Das Öl soll nach Verlassen der Bohrungen in einen radial betrachtet nach außen und unterhalb des Lamellenpakets vorgesehenen Ölfangraum geleitet werden. Hierbei weist der Ölfangraum eine Fangkante auf, die verhindern soll, dass das Öl nach Verlassen der Bohrung zur Kühlung der Lamellen nicht mehr zur Verfügung steht. Dies ist jedoch nicht immer der Fall, da das Öl, insbesondere bei hohen Drehzahlen nach Verlassen der Bohrungen über die Fangkante hinausspritzt und somit nicht zur Kühlung der Lamellen verwendet werden kann.For example, is from the DE 10 2010 039 171 A1 known to perform the holes in relation to the hub area axially parallel to the disk carrier longitudinal axis. The oil should be passed after leaving the holes in a radially outwardly provided and below the disk pack provided for oil catchment space. Here, the oil catchment area has a catching edge, which is to prevent the oil after leaving the hole for cooling the slats is no longer available. However, this is not always the case, since the oil, in particular at high speeds after leaving the holes on the catch edge splashes and thus can not be used to cool the slats.

Im Rahmen einer Weiterbildung der Erfindung wird vorgeschlagen, zusätzlich zur vorgeschlagenen Ausgestaltung der Bohrungen die Fangkante des Ölfangraums derart zu gestalten, dass das Volumen des Ölfangraums vergrößert wird. Vorzugsweise ist die Fangkante als steile Rampe ausgeführt, so dass aus den erfindungsgemäß ausgestalteten Bohrungen austretendes Öl, das auf die Fangkante trifft, in den Ölfangraum zurückgespritzt wird.As part of a development of the invention, it is proposed to design the catch edge of the oil catchment chamber in addition to the proposed design of the holes such that the volume of the oil catchment space is increased. Preferably, the catching edge is designed as a steep ramp, so that from the inventively designed holes leaking oil that meets the catching edge, is injected back into the oil catchment area.

Um die räumliche Verteilung des Öls zu optimieren, wird zudem vorgeschlagen, sechs Bohrungen vorzusehen.In order to optimize the spatial distribution of the oil, it is also proposed to provide six holes.

Durch die erfindungsgemäße Konzeption wird in kostengünstiger Weise gewährleistet, dass das aus den Bohrungen austretende Öl auch bei hohen Drehzahlen nicht an der Fangkante des Ölfangraums vorbeispritzt und somit zur Kühlung des Lamellenpakets zur Verfügung steht.The inventive concept is ensured in a cost effective manner that the emerging from the holes oil does not splash past even at high speeds at the catching edge of the oil collecting space and thus is available for cooling the plate pack.
