Description
Die Erfindung betrifft eine Schutzanordnung für einen Freiraum zwischen einem feststehenden Getriebegehäuseteil und einem im Fahrbetrieb eines Kraftfahrzeuges rotierenden Antriebswellengehäuseteil, wobei ein Wellenstück der als Antriebswellengehäuseteil zumindest teilweise ausgebildeten Antriebswelle in das Getriebegehäuseteil hineinreicht, wobei ein Wellendichtring zur Abdichtung des Wellenstückes gegenüber dem Getriebegehäuseteil vorgesehen ist.The invention relates to a protective arrangement for a free space between a fixed transmission housing part and a drive shaft housing part rotating during driving operation of a motor vehicle, wherein a shaft piece of the drive shaft, which is at least partially designed as a drive shaft housing part, extends into the transmission housing part, wherein a shaft sealing ring is provided for sealing the shaft part from the transmission housing part.
Um den Freiraum zwischen dem feststehenden Getriebegehäuseteil und dem im Fahrbetrieb des Kraftfahrzeuges rotierenden Antriebswellengehäuseteil von Schmutz freizuhalten und damit den Wellendichtring vor einem erhöhten Verschleiß zu schützen, ist es beispielsweise aus der
Aufgabe der Erfindung ist es daher, den oben genannten Nachteil auf einfache und kostengünstige Weise zu vermeiden.The object of the invention is therefore to avoid the above-mentioned disadvantage in a simple and inexpensive manner.
Diese Aufgabe wird dadurch gelöst, dass ein Schutzring vorgesehen ist, der mindestens zwei Schenkel aufweist, wobei ein erster, axialer Schenkel zum Zusammenwirken mit einer in Axialrichtung verlaufenden Mantelfläche des Antriebswellengehäuseteils und ein zweiter, radialer Schenkel zum Zusammenwirken mit einer in Radialrichtung verlaufenden Oberfläche des Getriebegehäuseteils vorgesehen sind, wobei der Schutzring kraft- und/oder formschlüssig mit dem Antriebswellengehäuseteil verbunden ist. Hierdurch wird auf einfache Weise ein Schutz des Freiraumes gewährleistet. Durch eine derartige, ringförmige Ausgestaltung ist es zudem möglich, den Schutzring in einen bestimmten Bereich für unterschiedliche Antriebswellengehäuseteile einzusetzen.This object is achieved in that a protective ring is provided which has at least two legs, a first, axial leg for interacting with an axially extending lateral surface of the drive shaft housing part and a second, radial leg for interacting with a radial surface of the transmission housing part are provided, wherein the protective ring is non-positively and / or positively connected to the drive shaft housing part. Protection of the free space is thereby ensured in a simple manner. Such an annular configuration also makes it possible to use the protective ring in a specific area for different drive shaft housing parts.
In einer besonders vorteilhaften Ausführungsform ist ein dritter, radialer Schenkel zum Zusammenwirken mit einer in Radialrichtung verlaufenden Oberfläche des Antriebswellengehäuseteils vorgesehen. Dieser dritte Schenkel erhöht zum einen die Schutzwirkung und zum anderen kann er als Angriffsfläche beim Aufpressprozess des Schutzringes auf das Antriebswellengehäuseteil dienen.In a particularly advantageous embodiment, a third, radial leg is provided for interacting with a surface of the drive shaft housing part that extends in the radial direction. This third leg increases the protective effect on the one hand and on the other hand it can serve as a contact surface during the process of pressing the protective ring onto the drive shaft housing part.
In einer besonders vorteilhaften Ausführungsform ist ein vierter, axialer Schenkel zum Zusammenwirken mit einer in Axialrichtung des Getriebegehäuseteils verlaufenden Stegfläche vorgesehen. Hierdurch wird der vorliegende Freiraum zwischen Getriebegehäuseteil und Antriebswellengehäuseteil noch einmal verkleinert und verkompliziert, was dazu führt, dass die Gefahr, dass Schmutz eindringt, noch einmal deutlich verringert werden kann.In a particularly advantageous embodiment, a fourth, axial leg is provided for interacting with a land surface running in the axial direction of the gear housing part. As a result, the available space between the transmission housing part and the drive shaft housing part is further reduced and complicated, which means that the risk of dirt penetrating can be significantly reduced again.
Es hat sich als vorteilhaft erwiesen, dass der Schutzring als Spritzgussteil hergestellt ist. Hierbei ist es insbesondere vorteilhaft wenn er aus Kunststoff gefertigt ist.It has proven to be advantageous that the protective ring is produced as an injection molded part. It is particularly advantageous here if it is made of plastic.
Um eine sichere Befestigung am Antriebswellengehäuseteil zu gewährleisten, kann der erste Schenkel zum Antriebswellengehäuseteil gerichtete Formschlussmittel aufweisen.In order to ensure secure attachment to the drive shaft housing part, the first leg can have positive locking means directed towards the drive shaft housing part.
In besonders vorteilhafter Weise ist das Antriebswellengehäuseteil als Gelenkwellengehäuseteil ausgebildet, aufgrund eines dritten Schenkels.In a particularly advantageous manner, the drive shaft housing part is designed as an articulated shaft housing part, due to a third leg.
