Abstract

The resilient protective sleeve (16) which excludes dirt etc. from the moving parts of a universal joint, as in the main patent, has one end (17) retained on the cup shaped part (19) of the end of one shaft and the other end (5) fitted around the end of the second shaft. In front of the concave surface (9) of the sleeve is a funnel shaped spacer ring (6), which may be made of steel. This forms the front part of a sleeve (7) which fits over the portion of the resilient sleeve around the second shaft. The front part has elongated holes (15) which form a self cleaning device for the second shaft. The part of the resilient sleeve (5) around the first shaft is also protected by a further metal sleeve (4).

Der Erfindung liegt die Aufgabe zugrunde, den Gegenstand der Hauptpatentanmeldung durch eine besondere Ausbildung des Distanzelementes zur Distanzierung der beiden Ringe des Rollbalges weiterzuentwickeln und so zu vervollkommnen, dass nicht nur eine Verbesserung der Funktion sondern auch ein optimaler Schutz gegen jede Art einer mechanischen Beschädigung von aussen mit einfachen Mitteln erreicht wird.The invention is based on the object of the main patent application by a special design of the spacer element to distance the two To further develop the rings of the rolling bellows and to perfect them in such a way that not only an improvement of the function but also an optimal protection against any kind mechanical damage from the outside is achieved with simple means.

Diese Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Distanzelement aus einem Panzerring herauswächst, welcher aus einem Werkstoff von höherer Festigkeit, beispielsweise Stahl, gefertigt ist, und der den äusseren Ring des Rollbalges gelten Beschädigungen von aussen schützt. Hierbei ist das Distanzelement mit einer Vielzahl von Durchbrüchen versehen, welche eine Selbstreinigung des Rollelementes von Verschmutzungen ermöglichen. These This object is achieved according to the invention solved that the spacer grows out of an armored ring, which from a Material of higher strength, such as steel, is made, and the The outer ring of the bellows protects against damage from the outside. Here is the spacer element is provided with a large number of openings which allow self-cleaning enable the rolling element to remove dirt.

Der innere Ring des Rollbalges ist hierbei von einem Panzerring umhüllt, dessen Aussendurchmesser nach Erreichen eines bestimmten Beugungswinkels gegen den Innendurchmesser des Distanzelementes schlägt, sodass es bei einer weiteren Vergrösserung des Beugungswinkels zu einer Zwangs steuerung der Winkelbewegung des äusseren Ringes des Rollbalges kommt.The inner ring of the bellows is encased in an armored ring, its outside diameter after reaching a certain diffraction angle against the The inner diameter of the spacer element suggests that it is a further enlargement the flexion angle to a forced control of the angular movement of the outer ring of the bellows comes.

Die Erfindung wird an Hand der Zeichnung an einem Ausführungsbeispiel beschrieben. Es zeigt Fig.1 einen Längsschnitt durch einen winkelbeweglichen Rollbalg gemäss der Erfindung am Anwendungsbeispiel einer Abdichtung für eine Drehgelenkkupplung zum Antrieb der Räder eines Kraftfahrzeuges, die. als Gleichlaufverschiebegelenk ausgebildet ist, und Fig.2 einen Querschnitt durch Fig. 1 an der Verbindung des inneren Ringes des Rollbalges mit der Gelenkwelle.The invention is based on the drawing using an exemplary embodiment described. FIG. 1 shows a longitudinal section through an angularly movable rolling bellows according to the invention using the example of a seal for a swivel joint coupling to drive the wheels of a motor vehicle that. as a constant velocity joint is formed, and Fig.2 shows a cross section through Fig. 1 at the connection of the inner ring of the bellows with the cardan shaft.

Der winkelbewegliche Rollbalg 1, der aus einem elastisch verformbaren Werkstoff, beispielsweise Gummi, gefertigt ist, besteht aus einem äusseren Ring 8 zur dichten Verbindung mit dem äusseren Kupplungsteil 13, 19 der Drehgelenkkupplung, einem inneren Ring 5 zur dichten Verbindung mit der Gelenkwelle 2 und einem diese beiden Ringe verbindenden Rollelement 9, welches so gewölbt ist, dass die konvexe Seite der Wölbung der Drehgelenkkupplung zugekehrt ist. Die Verbindung des äusseren Ringes 8 des Rollbalges mit dem äusseren Kupplungsteil der Drehgelenkkupplung ist in zwei verschiedenen Ausftihrungsformen dargestellt. Bei der in der.The angularly movable bellows 1, which consists of an elastically deformable Material, for example rubber, is made, consists of an outer ring 8 for a tight connection with the outer coupling part 13, 19 of the swivel joint coupling, an inner ring 5 for a tight connection with the cardan shaft 2 and one of these two rings connecting rolling element 9, which is curved so that the convex Side facing the curvature of the swivel coupling. The connection of the outside Ring 8 of the rolling bellows is with the outer coupling part of the swivel coupling shown in two different versions. In the case of the.

oberen oberen Hälfte der Fig.1 dargestellten Ausführungsform wird das Ende 17 des äusseren Ringes 8 mittels eines Spannringes 18, der um einen Bund des äusseren Kupplungsteiles 19 gebördelt ist, direkt angedrückt und unlösbar verbunden. Bei der unteren Ausführungsform ist das Ende 12 des äusseren Ringes 8 in einen Zwischenring 11 eingeklemmt, der über Schrauben 14 lösbar mit dem äusseren Kupplungsteil 13 verbunden ist. Über die Sicken 10, 16 kommt eine kardanische Verbindung des äusseren Ringes 8 mit dem äusseren Kupplungsteil 13, 19 zustande, welche eine Zwangs steuerung der Winkelbewegung des äusseren Ringes 8 erlaubt. Das Distanzelement 6 wächst aus einem Panzerring 7 heraus, welcher aus einem Werkstoff von höherer Festigkeit, beispielsweise Stahl, gefertigt ist, und der den äusseren Ring 8 des Rollbalges gegen Beschädigungen von aussen schützt. upper upper half of Figure 1 illustrated embodiment is the end 17 of the outer ring 8 by means of a clamping ring 18, which is around a The collar of the outer coupling part 19 is crimped, pressed directly and undetachable tied together. In the lower embodiment, the end 12 of the outer ring 8 is clamped in an intermediate ring 11, which is detachable via screws 14 with the outer Coupling part 13 is connected. A cardanic connection is made via the beads 10, 16 of the outer ring 8 with the outer coupling part 13, 19 which is a Forced control of the angular movement of the outer ring 8 is allowed. The spacer element 6 grows out of an armored ring 7, which is made of a material of higher Strength, for example steel, is made, and the outer ring 8 of the Protects roll bellows against external damage.

Es ist mit einer Vielzahl von Durchbrüchen 15 versehen, welche eine Selbstreinigung des Rollelementes 9 von Verschmutzungen ermöglichen. Der innere Ring 5 des Rollbalges, der mittels des Klemmringes 3 fest mit der Gelenkwelle 2 verbunden ist, ist von einem Panzerring 4 umhüllt, dessen Aussendurchmesser nach Erreichen eines bestimmten Beugungswinkels 21 gegen den Innendurchmesser des Distanzelementes 6 schlägt, soldass es bei einer weiteren Vergrösserung 22 des Beugungswinkels 23 der Drehgelenkkupplung zu einer Zwangssteuerung der Winkelbewegung des äusseren Ringes 8 des Rollbalges kommt. 20 sind die Verschiebewege der als Gleichlaufverschiebegelenk ausgebildeten Drehgelenkkupplung.It is provided with a plurality of openings 15, which one Allow self-cleaning of the rolling element 9 from dirt. The inner one Ring 5 of the rolling bellows, which by means of the clamping ring 3 is firmly attached to the cardan shaft 2 is connected, is encased by an armored ring 4, the outer diameter of which according to Achieving a certain deflection angle 21 against the inner diameter of the spacer element 6 suggests that it is at a further enlargement 22 of the diffraction angle 23 the swivel coupling to a forced control of the angular movement of the outer Ring 8 of the rolling bellows comes. 20 are the displacement paths of the constant velocity displacement joint trained swivel coupling.
