Bei den bekannten Ausführungen, bei denen die Kardanwellenlager in Büchsen untergebracht sind, handelt es sich um die Lagerung der Wellen in zwei Büchsen, die mittels Flansche mit einem Stutzen in Verbindung gebracht sind und in diesem und im Getriebegehäusekasten frei ausladen, wodurch während des Antriebes leicht Schwingungen auftreten. Außerdem ist die Kardanwelle aus denIn the known designs in which the cardan shaft bearings are housed in sleeves are, it is the storage of the shafts in two bushes, which means Flanges are brought into connection with a nozzle and in this and in the transmission housing box unload freely, whereby vibrations occur easily during the drive. In addition, the cardan shaft is from the
ίο Büchsen nur nach einer Richtung hin herausnehmbar, und es muß zu diesem Zwecke das jeweilige Kegelrad von dieser Welle abgenommen werden.ίο bushings can only be removed in one direction, and for this purpose the respective bevel gear must be removed from this shaft.
Zweck der Erfindung ist die Beseitigung dieses Mißstandes durch die Anordnung der Kardanwellenlager in einer in einem Stutzen des Wechselgetriebekastens passend geführten bzw. eingespannten Büchse, die die Unterbringung eines oder zweier Kegelräder und der Wellen und die Herausnahme derselben ohne die Abnahme der Kegelräder ermöglicht.The purpose of the invention is to remedy this deficiency by the arrangement of the Cardan shaft bearings in a suitably guided in a connection piece of the gear box or clamped bushing, which accommodates one or two bevel gears and the Allows shafts and the removal of the same without removing the bevel gears.
Die Zeichnung zeigt den Erfindungsgegenstand in einer beispielsweisen Ausführungsform im Mittelschnitt.The drawing shows the subject matter of the invention in an exemplary embodiment in the middle cut.
Die als Kugellager ausgebildeten Lager a, b der im gezeichneten Falle als Doppel- bzw. als Vollwelle c und Hohlwelle d ausgeführten Kardanwelle sind in einer Büchse e untergebracht. Diese weist am vorderen Ende einen Bund f auf und ist in einem Flanschstutzen g des Differenjtialgetriebekastens h eingeschoben. Letzterer ist zugleich der Anschlußstutzen für das Kardanstützrohr i mit dem Führungsflansch k. Der Bund f der Lagerbüchse e ist zwischen den Stirnflächen der Flansche des Gehäusestutzens g und des Kardanstützrohres i gelegen, und es wird diese Büchse durch Anziehen der Verbindungsschrauben I sowohl gegen Drehung als auch gegen achsiale Verschiebung gesichert und mithin festgelegt. The bearings a, b designed as ball bearings of the cardan shaft, which in the illustrated case is designed as a double or solid shaft c and hollow shaft d , are accommodated in a bushing e. This has a collar f at the front end and is pushed into a flange connection g of the differential gear box h. The latter is also the connection piece for the cardan support tube i with the guide flange k. The collar f of the bearing bushing e is located between the end faces of the flanges of the housing stub g and the cardan support tube i , and this bushing is secured against rotation and axial displacement by tightening the connecting screws I and is therefore secured.
Die Kegelradzahnkränze m und η der VoIl- und der Hohlwelle c und d greifen in die Zahnkränze 0 eines Rades des im Differentialgetriebekasten h gelegenen Getriebes ein, das den Antrieb der Hinterradachse des Kraftwagens vermittelt. Im Bereiche der Radeingriffsstellen bzw. im Bahnbereiche der Radzahnkränze 0 ist die Lagerbüchse e entsprechend ausgeschnitten.The bevel gear rims m and η of the full and the hollow shaft c and d mesh with the ring gears 0 of a wheel of the transmission located in the differential gear box h , which drives the rear wheel axle of the motor vehicle. In the area of the wheel engagement points or in the path area of the gear rims 0, the bearing bush e is cut out accordingly.
Durch die Unterbringung der Kugellager a, b in der Büchse ist ein sicherer Halt dieser Lager erreicht, und es ist eine leichte Freilegung der Getrieberäder m, η möglich, wie sich auch der Zusammenbau der Gehäuse- und Getriebeteile wesentlich vereinfacht. Auch ist hierdurch eine genaue Einstellung und Prüfung des richtigen Eingriffes der Zahnräder vor dem Zusammenbau möglich.By accommodating the ball bearings a, b in the bushing, a secure hold of these bearings is achieved, and the gear wheels m, η can be easily exposed, and the assembly of the housing and gear parts is also considerably simplified. This also enables precise setting and checking of the correct engagement of the gears before assembly.
