Description

  

      Kreuzgelenk       Die vorliegende Erfindung bezieht sich auf ein  Kreuzgelenk, dessen Zapfen mittels Wälzkörpern  gegenüber den Gelenkgabeln drehbar gelagert sind.  



  Bei den bisher bekannten Ausführungen liegen  die Wälzkörper unmittelbar zwischen den Zapfen und  der als Laufbüchse ausgebildeten Lagerbüchse. Hier  bei ergab sich zunächst einmal der Nachteil, dass die  genannten Laufflächen besonders sorgfältig ausgebil  det werden mussten. Ausserdem war es erforderlich,  zum axialen Festlegen der Wälzkörper zusätzliche  Lagerscheiben vorzusehen.  



  Um diese Nachteile zu vermeiden, wird gemäss  der Erfindung vorgeschlagen, die     Wälzkörper    auf  einem auf jeden Zapfen     aufgepressten        Innenlaufring     anzuordnen und gegen axiale Verschiebung mittels  an diesem Laufring vorgesehener Schultern zu sichern.  Hierbei kann jedes beliebige, bekannte Wälzlager  ohne Käfig verwendet werden; vorzugsweise werden  jedoch Rollenlager angewendet.  



  Bei der praktischen Ausführung ist in die Boh  rung der Gelenkgabel ein     Aussenlaufring    für die     Wälz-          körper        eingepasst.    Dadurch kann das Lager und da  mit das gesamte Gelenk durch einen in radialer Rich  tung gegen den     Aussenlaufring    wirkenden und mit  einem Stirnlager für den Zapfen versehenen, auf die  Gelenkgabel     aufschraubbaren    Lagerdeckel gegenüber  der Gelenkgabel radial eingestellt werden. Dadurch  wird eine besonders genaue Einstellung der Kreuz  gelenke möglich.  



  Es ist jedoch auch möglich, die in an sich be  kannter Weise in die Bohrung der Gelenkgabel ein  gepasste Lagerbüchse als     Aussenlaufring    für die     Wälz-          körper    auszubilden. In diesem Fall muss man aller  dings auf die radiale     Einstellbarkeit    durch den oben  beschriebenen Lagerdeckel verzichten.  



  In der beiliegenden Zeichnung sind Ausführungs  beispiele des Erfindungsgegenstandes dargestellt, und  zwar zeigt         Fig.    1 ein Gelenk mit aufgeschraubtem Lager  deckel und       Fig.    2 ein Gelenk mit einer in die Gelenkgabel  eingesetzten Lagerbüchse.  



  Auf dem Zapfen 1 ist ein     Wälzlager    2 angeordnet,  das zur Lagerung des Zapfens gegenüber der Ge  lenkgabel 4 dient. Das Lager 2 besteht aus einem       Innenlaufring    3, auf dem Rollen 6 laufen, die mittels  am Laufring angeordneter Schultern 5 gegen axiale  Verschiebung gesichert sind. Bei der Ausführung ge  mäss     Fig.    1 ist ausserdem ein     Aussenlaufring    7 vor  gesehen, der in die Bohrung 8 in der Gelenkgabel 4       eingepasst    ist. An seinem oberen Ende weist der       Aussenlaufring    eine Schulter 7a auf, die auf der Ge  lenkgabel 4 aufliegt.

   Bei der Ausführung gemäss     Fig.    1       sind    Zapfen 1 und Lager 2 mittels eines Lagerdeckels  9 abgedeckt, in dem ein bekanntes Stirnlager. 10 für  den Zapfen 1 angeordnet ist. Der Lagerdeckel 9 ist  so ausgebildet, dass er in radialer Richtung gegen die  Schulter 7a des     Aussenlaufringes    wirkt, wodurch eine  radiale Verstellung des Zapfens 1 mit dem Lager 2  ermöglicht ist. Befestigt ist der Lagerdeckel 9 an der  Gelenkgabel 4 mittels Schrauben 11. Das Lager 2 ist  zur Mitte des Kreuzgelenkes mittels einer beliebigen  Dichtung 12 abgedichtet.  



  Bei der Ausführung gemäss     Fig.    2 ist das Lager 2  in einer Lagerbüchse 13 angeordnet, die gleichzeitig  als     Aussenlaufring    für die Rollen ausgebildet ist.  Auch in dieser Lagerbüchse 13 ist ein Stirnlager 10  vorgesehen. Die Büchse 13 ist in der Gabel 4 mittels  eines schulterförmigen Ansatzes     13a    gegen axiale  Verschiebung gesichert.



      Universal joint The present invention relates to a universal joint, the pins of which are rotatably mounted relative to the joint yokes by means of rolling elements.



  In the designs known up to now, the rolling elements are located directly between the pin and the bearing bush, which is designed as a liner. In this case, there was initially the disadvantage that the mentioned running surfaces had to be specially trained. In addition, it was necessary to provide additional bearing washers for axially fixing the rolling elements.



  In order to avoid these disadvantages, it is proposed according to the invention to arrange the rolling elements on an inner race that is pressed onto each journal and to secure them against axial displacement by means of shoulders provided on this race. Any known roller bearing without a cage can be used here; however, roller bearings are preferably used.



  In the practical version, an outer race ring for the rolling elements is fitted into the bore of the joint fork. As a result, the bearing and there with the entire joint can be adjusted radially with respect to the joint yoke by a bearing cover which can be screwed onto the joint fork and which acts in the radial direction against the outer race and is provided with an end bearing for the pin. This enables a particularly precise adjustment of the cross joints.



  However, it is also possible to design the bearing bush fitted in the bore of the joint fork in a manner known per se as an outer race for the rolling elements. In this case you have to do without the radial adjustability through the bearing cover described above.



  In the accompanying drawings, embodiment examples of the subject invention are shown, namely Fig. 1 shows a joint with screwed-on bearing cover and Fig. 2 shows a joint with a bearing bush inserted into the joint fork.



  On the pin 1, a roller bearing 2 is arranged, which is used to support the pin against the steering fork 4 Ge. The bearing 2 consists of an inner race 3 on which rollers 6 run, which are secured against axial displacement by means of shoulders 5 arranged on the race. In the embodiment according to FIG. 1, an outer race 7 is also seen in front of which is fitted into the bore 8 in the joint fork 4. At its upper end, the outer race has a shoulder 7a which rests on the steering fork 4.

   In the embodiment according to FIG. 1, pin 1 and bearing 2 are covered by means of a bearing cover 9 in which a known end bearing. 10 is arranged for the pin 1. The bearing cover 9 is designed so that it acts in the radial direction against the shoulder 7a of the outer race, whereby a radial adjustment of the journal 1 with the bearing 2 is made possible. The bearing cover 9 is fastened to the joint fork 4 by means of screws 11. The bearing 2 is sealed off from the center of the universal joint by means of any seal 12.



  In the embodiment according to FIG. 2, the bearing 2 is arranged in a bearing bush 13, which is also designed as an outer race for the rollers. A front bearing 10 is also provided in this bearing bush 13. The sleeve 13 is secured in the fork 4 against axial displacement by means of a shoulder-shaped extension 13a.
