Abstract
Es wird eine Flachdichtung (4) zur Abdichtung zweier Gehäusehälften und zur Abschirmung eines Entlüftungsraums eines Fahrzeuggetriebes vorgeschlagen, welche ein im montierten Zustand nicht zwischen den Gehäusehälften eingespanntes Teil (5) umfasst, das in den Gehäuseinnenraum hineinragt und derart dimensioniert und angeordnet ist, dass der Entlüftungsraum abgeschirmt wird.It is proposed a gasket (4) for sealing two housing halves and for shielding a vent space of a vehicle transmission, which comprises a not clamped in the assembled state between the housing halves part (5) which projects into the housing interior and is dimensioned and arranged such that the Venting space is shielded.
Description
Die Erfindung betrifft eine Flachdichtung zur Abdichtung zweier Gehäusehälften und zur Abschirmung eines Entlüftungsraums eines Fahrzeuggetriebes gemäß dem Oberbegriff des Patentanspruchs 1. The invention relates to a flat gasket for sealing two housing halves and for shielding a venting space of a vehicle transmission according to the preamble of
Aus dem Stand der Technik ist bekannt, zur Entlüftung des Innenbereichs eines Gehäuses eines Fahrzeuggetriebes, umfassend zwei zusammengeflanschte Gehäusehälften, ein Labyrinth mit einem Beruhigungsraum als Entlüftungsraum vorzusehen, wobei der Entlüftungsraum mittels einer eingepressten Abdeckscheibe abgeschirmt wird. Durch das Labyrinth werden ein Eindringen von Schmutz und ein Austreten von Getriebeöl verhindert. From the prior art it is known to provide for venting the inner region of a housing of a vehicle transmission, comprising two flanged housing halves, a labyrinth with a calming space as a vent space, wherein the vent space is shielded by means of a pressed-cover. The labyrinth prevents the ingress of dirt and leakage of gear oil.
Die Abdeckscheibe wird in den Entlüftungsraum eingepresst, was in nachteiliger Weise in einem erheblichen Montageaufwand resultiert. Des Weiteren sind die Anforderungen an die Form-, Lage- und Oberflächengenauigkeit für den Presssitz der Abdeckscheibe sehr hoch. Zudem ist eine hohe Gussgenauigkeit für den Presssitz der Abdeckscheibe erforderlich; alternativ muss die Genauigkeit mittels einer spanenden Bearbeitung gewährleistet werden. The cover is pressed into the vent space, resulting in a disadvantageous manner in a considerable installation effort. Furthermore, the demands on the form, position and surface accuracy for the press fit of the cover are very high. In addition, a high accuracy casting for the interference fit of the cover is required; Alternatively, the accuracy must be ensured by means of a machining.
Die zwei Gehäusehälften werden mittels einer Metall-Elastomer-Flachdichtung gegeneinander abgedichtet, wodurch eine Ölleckage verhindert wird. The two housing halves are sealed against each other by means of a metal-elastomeric flat gasket, whereby oil leakage is prevented.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Flachdichtung zur Abdichtung zweier Gehäusehälften und zur Abschirmung eines Entlüftungsraums eines Fahrzeuggetriebes anzugeben. The present invention has for its object to provide a flat gasket for sealing two housing halves and for shielding a vent space of a vehicle transmission.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor. This object is solved by the features of
Demnach wird eine Flachdichtung zur Abdichtung zweier Gehäusehälften und zur Abschirmung eines Entlüftungsraums eines Fahrzeuggetriebes vorgeschlagen, umfassend ein im montierten Zustand nicht zwischen den Gehäusehälften eingespanntes Teil, das in den Gehäuseinnenraum hineinragt und derart dimensioniert und angeordnet ist, dass der Entlüftungsraum abgeschirmt wird. Accordingly, a flat gasket for sealing two housing halves and for shielding a vent space of a vehicle transmission is proposed, comprising a not clamped in the assembled state between the housing halves part which projects into the housing interior and is dimensioned and arranged such that the vent space is shielded.
Durch die erfindungsgemäße Konzeption wird die Funktion der Abdichtung des Entlüftungsraums von der Flachdichtung übernommen. Dadurch entfällt die Notwendigkeit einer Abdeckscheibe und deren Montage sowie der Form-, Lage- und Oberflächengenauigkeit für den Presssitz der Abdeckscheibe. Due to the conception according to the invention, the function of sealing the venting space is taken over by the flat gasket. This eliminates the need for a cover and its mounting and the form, position and surface accuracy for the interference fit of the cover.
Gemäß der Erfindung kann die Flachdichtung als Metallsickendichtung, als Metallelastomerdichtung, als Papierdichtung oder auch als Dichtung aus Verbundstoffen ausgeführt sein. According to the invention, the flat gasket may be designed as a metal bead seal, as a metal elastomer seal, as a paper seal or as a seal made of composite materials.
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:
