Abstract
Es wird ein Ölbehälter (1) in einem Automatgetriebe (5) eines Kraftfahrzeugs vorgeschlagen, der von einem Parksperrenrad (2) abgeschleudertes Spritzöl auffängt und durch einen eine Lagerung (8) einer Abtriebswelle (3) des Getriebes (5) umschließenden Gehäuseinnenbereich zwischen dem Parksperrenrad (2) des Getriebes (5) und dem Abtrieb und einen axial an das Parksperrenrad (2) angrenzenden Abschirmdeckel (4) gebildet ist.An oil container (1) in an automatic transmission (5) of a motor vehicle is proposed which absorbs spray oil spun off by a parking lock gear (2) and a housing inner region between the parking lock gear enclosing a bearing (8) of an output shaft (3) of the transmission (5) (2) of the transmission (5) and the output and an axially to the parking lock gear (2) adjacent shielding cover (4) is formed.
Description
Die vorliegende Erfindung bezieht sich auf einen Ölbehälter in einem Automatgetriebe eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to an oil reservoir in an automatic transmission of a motor vehicle according to the preamble of
Das Ölvolumen des Öls in einem Getriebe ändert sich signifikant in Abhängigkeit der Temperatur, so dass eine an Hochtemperatur, beispielsweise an 130°C angepasste Ölmenge sich beim Kaltzustand als gering erweist und somit in nachteiliger Weise zu Luftansaugung führt. Eine an Niedrigtemperatur, beispielsweise an -30°C angepasste Ölmenge erweist sich ist bei Hochtemperatur als zu viel und führt zur Überflutung von Schaltelementen des Getriebes. Aus diesen Gründen entsteht die Notwendigkeit, wegen Wärmeausdehnung erzeugtes zusätzliches Ölvolumen getrennt von rotierenden Bauteilen zu speichern.The oil volume of the oil in a transmission changes significantly as a function of the temperature, so that an adjusted to high temperature, for example at 130 ° C oil amount turns out to be low in the cold state and thus leads to adverse air intake. An adapted to low temperature, for example, to -30 ° C oil amount proves to be too high at high temperature and leads to the flooding of switching elements of the transmission. For these reasons, there is a need to store additional oil volume generated due to thermal expansion separately from rotating components.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Ölbehälter in einem Automatgetriebe eines Kraftfahrzeugs zu schaffen. Hierbei soll die Dimensionierung des Getriebes beibehalten werden.The present invention has for its object to provide an oil reservoir in an automatic transmission of a motor vehicle. Here, the dimensioning of the transmission should be maintained.
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
Demnach wird ein Ölbehälter in einem Automatgetriebe eines Kraftfahrzeugs vorgeschlagen, in den vom Parksperrenrad abgeschleudertes Spritzöl gelangt, welcher durch einen die Abtriebswellenlagerung umschließenden Gehäuseinnenbereich zwischen einem Parksperrenrad des Getriebes und dem Abtrieb und einen axial an das Parksperrenrad angrenzenden Abschirmdeckel gebildet ist, wobei der Abschirmdeckel an seinem dem Ölsumpf des Getriebes zugewandten unteren Bereich zumindest eine Ablaufbohrung aufweist.Accordingly, an oil tank is proposed in an automatic transmission of a motor vehicle, in the thrown off the parking lock gear splash oil, which is formed by a shaft surrounding the output shaft housing between a parking lock gear of the transmission and the output and an axially adjacent to the parking lock screen cover, wherein the shield cover at his Having the oil sump of the transmission facing lower portion has at least one drain hole.
Gemäß der Erfindung ist die zumindest eine Ablaufbohrung derart dimensioniert, dass weniger Öl abläuft, als vom Parksperrenrad abgeschleudertes Spritzöl in den Ölbehälter gelangt.According to the invention, the at least one drain hole is dimensioned such that less oil runs off as spilled by the parking lock gear splash oil passes into the oil reservoir.
Der Abschirmdeckel kann ringscheibensegmentförmig sein und die Abtriebswellenlagerung konzentrisch umschließen.The shield cover may be annular segment-shaped and concentrically surround the output shaft bearing.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Gleiche Bezugszeichen in den Figuren bezeichnen gleiche Bauteile. Es zeigen:
