Abstract
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.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen topfförmigen Lamellenträger eines Lamellenschaltelementes eines Getriebes eines Kraftfahrzeugs anzugeben, der derart ausgestaltet ist, dass ein Vorbeispritzen des Öls an der Fangkante verhindert wird.The present invention has for its object to provide a cup-shaped plate carrier of a plate switching element of a transmission of a motor vehicle, which is designed such that a Vorbeispritzen the oil is prevented at the catching edge.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.This object is solved by the features of patent claim 1. Further embodiments and advantages of the invention will become apparent from the dependent claims.
Demnach wird ein topfförmiger Lamellenträger eines Lamellenschaltelementes eines Getriebes eines Kraftfahrzeugs vorgeschlagen, welcher im Nabenbereich mehrere umfangsverteilt angeordnete, achsparallel zur Lamellenträgerlängsachse angeordnete Bohrungen aufweist, durch die Öl in einen seitlich des Topfbodens und radial betrachtet nach außen unterhalb des Lamellenpakets vorgesehenen Ölfangraum geleitet wird, wobei die Bohrungen derart gestaltet sind, dass sie den Topfboden radial betrachtet unterhalb ihrer Längsachse nicht durchdringen und den Topfboden radial betrachtet oberhalb ihrer Längsachse durchdringen, so dass aus diesen Bohrungen austretendes Öl auch bei hohen Drehzahlen des Lamellenträgers in den Ölfangraum geleitet wird.Accordingly, a cup-shaped plate carrier of a lamellar switching element of a transmission of a motor vehicle is proposed, which has a plurality circumferentially distributed arranged axially parallel to the disk carrier longitudinal axis bores, is passed through the oil in a side of the pot bottom and radially outwardly provided below the disk pack oil catchment space, wherein the Holes are designed such that they do not penetrate the bottom of the pot viewed radially below its longitudinal axis and penetrate the bottom of the pot viewed radially above its longitudinal axis, so that exiting from these holes escaping oil is passed at high speeds of the disk carrier in the oil sump.
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.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es zeigen:The invention will be explained in more detail below by way of example with reference to the attached figures. Show it:
