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.
