Diese Feder stützt sich gegen einen Ansatz des Zapfens 1 ab und ist von einem U-förmigen Ring 6 umgeben, der als Schutzring für die Dichtung dient und der vorteilhaft auf den Kreuzgelenkzapfen 1 aufgepreßt ist. Die Flachfeder 5 kann in einem U-förmigen Ring 7 aus elastischem Werkstoff untergebracht werden. Der Kreuzgelenkzapfen 1 kann auch in bekannter Weise mit einer Bohrung 1 a zur Zuführung und Aufnahme eines Schmiermittels versehen sein. Hierbei kann der Ring 4 in an sich bekannter Weise eine Nase od. dgl. erhalten, die in eine Aussparung des U-förmigen Ringes 6 eingreift, um den Ring 4 gegen Drehen zu sichern.In Fig. 1, the universal joint pin 1 is by means of the needles 2 in the Outer shell 3 stored. A ring 4 is used for sealing, in a known manner from a flat spring 5 or the like. Is loaded. This spring is supported against an approach of the pin 1 and is surrounded by a U-shaped ring 6, which acts as a protective ring serves for the seal and is advantageously pressed onto the universal joint pin 1 is. The flat spring 5 can be in a U-shaped ring 7 made of elastic material be accommodated. The universal joint pin 1 can also in a known manner with a Bore 1 a be provided for supplying and receiving a lubricant. Here the ring 4 can od in a known manner a nose Recess of the U-shaped ring 6 engages in order to secure the ring 4 against rotation.
Man erreicht so eine sehr gute und einwandfreie Abdichtung des Nadellagers, wobei das Eintreten von Schmutz und das Heraustreten von Fett vermieden wird.A very good and perfect seal of the needle bearing is achieved in this way, avoiding the entry of dirt and the exit of grease.
Bei dem Ausführungsbeispiel nach Fig. 2 findet ein Ring 4 Verwendung, der nicht mit planparallelen Flächen versehen ist, sondern bei dem die Fläche 8 kegelig verläuft, entsprechend der Stirnfläche der Außenschale 3. Bei diesem Ausführungsbeispiel ist die Feder 5 zwischen zwei winkelförmigen Ringen 9 und 10 angeordnet, deren axial gerichtete Flansche gegeneinanderliegen. Auch hierbei kann, falls es erforderlich ist, der Ring 4 gegen Drehen gesichert sein, indem er z. B. mit dem winkelförmigen Ring 9 verbunden wird.In the embodiment according to FIG. 2, a ring 4 is used, which is not provided with plane-parallel surfaces, but in which the surface 8 runs conically, corresponding to the end face of the outer shell 3. In this embodiment the spring 5 is arranged between two angular rings 9 and 10, the axial facing flanges are against each other. Here too, if necessary is, the ring 4 be secured against rotation by z. B. with the angular Ring 9 is connected.
