Abstract
Description
Die vorliegende Erfindung betrifft einen Planetenradsatz eines Getriebes eines Fahrzeuges gemäß der im Oberbegriff des Patentanspruches 1 näher definierten Art.The The present invention relates to a planetary gear set of a transmission of a vehicle according to the Preamble of claim 1 further defined type.
Automatikgetriebe für Fahrzeuge in Planetenbauweise sind aus der Fahrzeugtechnik hinreichend bekannt. Üblicherweise umfassen derartige Getriebe mehrere Planetenradsätze, denen mehrere Schaltelemente zugeordnet sind, um durch selektives Eingreifen verschiedene Übersetzungsverhältnisse zwischen der Antriebswelle und der Abtriebswelle des Fahrzeuges zu bewirken.automatic transmission for vehicles in planetary construction are sufficiently known from automotive engineering. Usually For example, such transmissions include a plurality of planetary gear sets having a plurality of shifting elements are assigned to by selective intervention different ratios between the drive shaft and the output shaft of the vehicle to effect.
Jeder Planetenradsatz umfasst einen Planetenträger an dem über Planetenbolzen gelagerte Planetenräder vorgesehen sind. Die Planetenräder kämmen sowohl mit einem Hohlrad als auch mit einem Sonnenrad. Um eine Schmierung des Planetenradsatzes und auch der Lagerung der Planetenräder zu gewährleisten, ist das Sonnenrad mit zumindest einem Ölversorgungskanal ausgerüstet ist. Das aus dem Ölversorgungskanal austretende Öl wird über zumindest eine Ölfangschale an dem Planetenträger zu den Lagerstellen der Planetenräder transportiert.Everyone Planetary gear includes a planet carrier on the planetary pin mounted planetary gears are provided. The planet wheels comb both with a ring gear and with a sun gear. To a lubrication of the planetary gear set and also to ensure the bearing of the planet gears, the sun gear is equipped with at least one oil supply channel. That from the oil supply channel escaping oil will be over at least an oil catcher to the planet carrier too the bearings of the planet gears transported.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Planetenradsatz der eingangs beschriebenen Gattung vorzuschlagen, bei dem die Ölversorgung weiter verbessert wird.Of the present invention is based on the object, a planetary gear to propose the genus described above, in which the oil supply is further improved.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen ergeben sich insbesondere aus den Unteransprüchen.These The object is achieved by the Characteristics of claim 1 solved. Further advantageous embodiments emerge in particular from the dependent claims.
Demzufolge wird ein Planetenradsatz für ein Getriebe eines Fahrzeuges, insbesondere für ein Automatikgetriebe vorgeschlagen, bei dem ein Planeten träger vorgesehen ist, an dem mehrere an Planetenbolzen gelagerte Planetenräder angeordnet sind, wobei an dem Planetenträger eine Ölfangschale bzw. ein Ölfangblech zum Leiten des Ölstromes vorgesehen ist. Ferner umfasst der erfindungsgemäße Planetenradsatz ein Sonnenrad mit zumindest einem Ölversorgungskanal, mit dem die Ölversorgung des Planetenradsatzes sichergestellt wird, wobei der Planetenträger zumindest eine Vertiefung als Öltasche oder dergleichen aufweist.As a result, becomes a planetary gear set for a transmission of a vehicle, in particular proposed for an automatic transmission, where a planet carrier is provided, arranged on the plurality of planetary gears mounted on planetary gears are, being at the planet carrier an oil catcher or an oil collector for conducting the oil flow is provided. Furthermore, the planetary gear according to the invention comprises a sun gear with at least one oil supply channel, with the oil supply the planetary gear set is ensured, wherein the planet carrier at least a depression as an oil pocket or the like.
Auf diese Weise kann zusätzliches Öl zur Schmierung des Planetenradsatzes aufgefangen werden, welches ansonsten nicht zur Schmierung zur Verfügung stehen würde. Somit kann die Ölversorgung bei dem erfindungsgemäßen Planetenradsatz optimiert werden.On This way can add extra oil for lubrication of the planetary gear set, which is otherwise not available for lubrication would stand. Thus, the oil supply in the planetary gear according to the invention be optimized.
Im Rahmen einer bevorzugten Ausführungsvariante der Erfindung kann der Planetenträger des vorgeschlagenen Planetenradsatzes als einteiliges Scheibenelement mit einer Innenkontur und mit Befestigungsbereichen für die Planetenbolzen ausgebildet sein. Als Werkstoff kann vorzugsweise ein Aluminiumguss oder dergleichen verwendet werden.in the Frame of a preferred embodiment The invention may be the planet carrier of the proposed planetary gear set as a one-piece disc element with an inner contour and with attachment areas for the Be formed planet pins. As a material may preferably a cast aluminum or the like can be used.
Bei einer solchen Ausgestaltung des Planetenträgers ist es besonders vorteilhaft, wenn am Umfang der Innenkontur des Planetenträgers zumindest eine Vertiefung als Öltasche vorgesehen ist. Somit kann das von innen nach radial außen spritzende Öl durch die Öltaschen aufgefangen und gesammelt werden, da sich die Öltaschen an der Innenkontur des Planetenträgers befinden. Es sind jedoch auch andere Anordnungsmöglichkeiten für die Ölauffangtaschen denkbar. Jedoch ist die Anordnung der Öltaschen an der Innenkontur bei einem Gussteil besonders vorteilhaft, da diese kostenneutral in die Gießform untergebracht werden können.at Such an embodiment of the planet carrier, it is particularly advantageous if at least one recess on the circumference of the inner contour of the planet carrier as an oil bag is provided. Thus, from the inside to the outside radially splashing oil through the oil pockets be caught and collected, as the oil pockets on the inner contour of the planet carrier are located. However, there are also other arrangements for the oil collecting bags conceivable. However, the arrangement of the oil pockets on the inner contour particularly advantageous in a casting, as this cost-neutral in the mold can be accommodated.
Vorzugsweise können mehrere Öltaschen am Umfang der Innenkontur gleichmäßig verteilt sein. Auf diese Weise kann das abspritzende Öl gleichmä ßig über den Umfang der Innenkontur des Planetenträgers aufgefangen und gesammelt werden. So ist es vorteilhaft, die gleiche Anzahl Öltaschen vorzusehen, wie der Planetenradsatz Planetenräder aufweist.Preferably can several oil pockets on Scope of the inner contour to be evenly distributed. In this way, the squirting oil gleichmä larly over the circumference of the inner contour of the planet carrier be collected and collected. So it is beneficial to the same Number of oil pockets to provide as the planetary gear planetary gears has.
Um das aufgefangene und gesammelte Öl zur Schmierung in die Ölfangschale zu leiten, kann gemäß einer nächsten Weiterbildung vorgesehen sein, dass die Vertiefungen jeweils in axialer Richtung eine Formschräge oder dergleichen aufweisen. Dadurch kann das Öl aus dem Bereich der Innenkontur des Planetenträgers in die Ölfangschale zur Ölverteilung transportiert werden. Durch die Wahl der Steigung an der Formschrägen kann eine gewünschte Strömungsrichtung und Strömungsgeschwindigkeit realisiert werden.Around the collected and collected oil for Lubrication in the oil tray to conduct, according to one next Be provided training that the wells each in axial direction a draft or the like. This allows the oil from the area of the inner contour of the planet carrier into the oil catcher for oil distribution be transported. By choosing the slope at the draft angles can a desired one flow direction and flow rate will be realized.
Ein mögliches Ausführungsbeispiel kann die Verwendung des erfindungsgemäßen Planetenradsatzes bei einem Achtgang-Automatikgetriebe als dritten Planetenradsatz vorsehen. Es sind jedoch auch andere Anwendungsbereiche denkbar.One potential embodiment can the use of the planetary gear according to the invention in a Provide eight-speed automatic transmission as the third planetary gear set. However, other applications are conceivable.
