Abstract
Description
Die Praxis kennt heute nur noch die Variante P 28 02 572. Es handelt sich dabei um eine stabile aber teuere Lösung. Die Zentrierscheibe verbunden mit der Kugelfassung unterliegt in ihrer Führung einer starken Beanspruchung durch Reibung, sobald ein Winkeleinschlag erfolgt.Practice only knows the variant P 28 02 572. It is a stable but expensive solution. The centering disc connected to the ball socket is subject to heavy strain in its management by friction as soon as there is an angle.
Der Erfindung liegt die Aufgabe zugrunde, ein preiswertes unkompliziertes und dauerhaftes Weitwinkelgelenk zu erstellen.The invention has for its object an inexpensive uncomplicated and permanent wide-angle joint too create.
Diese Aufgabe wird erfindungsgemäß durch den Patentanspruch 1 gelöst.This object is achieved by the claim 1 solved.
Eine weitere Ausbildung der Erfindung besteht in der Verstärkung oder Ersetzung des Lagers 8 durch ein Kugellager. Ferner kann durch den Einsatz oder den Entzug der Abstandsringe der Abstand der beiden Kreuzgelenke zueinander verändert werden. Die pilzartige Halbkugel, festverbunden mit dem Kreuzgelenk, kann durch die freibewegliche Rundschale ersetzt werden, die durch die kugelförmige kleine Abrundung des Kreuzgelenkes, oder an dessen Stelle durch einen fest verbundenen Ring, als Endseite des Kreuzgelenkes, in den Rohrabschnitt eingedrückt werden.Another embodiment of the invention consists in strengthening or replacing the bearing 8 with a ball bearing. Furthermore, the distance between the two universal joints can be changed by using or withdrawing the spacer rings. The mushroom-like hemisphere, firmly connected to the universal joint, can be replaced by the freely movable round shell, which is pressed into the pipe section by the spherical small rounding of the universal joint, or in its place by a firmly connected ring, as the end side of the universal joint.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß bei Umdrehungen der Gelenkwelle bereits bei geringer Verwinkelung die Halbkugeln und die bewegliche Rundscheibe mit ihrem Führungselement nicht mehr mitdrehen und daher keinen Reibwiderstand mit Abnutzung erzeugen. Die freibewegliche Rundschale, die die pilzartige Halbkugel ersetzt, bringt wesentliche Vorteile bei der Produktion, Haltbarkeit und Montage. Durch den Einsatz der Hülse, die eine teleskopische Wirkung erbringt, kann die Größe des Weitwinkelgelenkes verkleinert werden. The advantages achieved with the invention are in particular in that already at revolutions of the propeller shaft the hemispheres and the movable one at a slight angle Round disc no longer with its guide element turn and therefore no frictional resistance with wear produce. The free moving round bowl that the mushroom-like Hemisphere replaced, brings significant advantages in production, Durability and assembly. By using the The sleeve, which produces a telescopic effect, can The size of the wide-angle joint can be reduced.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden näher beschrieben:An embodiment of the invention is in the Drawing shown and described in more detail below:
Fig. 1 Weitwinkelgelenk bei 90° in Arbeitsstellung, Fig. 1 wide-angle joint at 90 ° in the working position,
Fig. 2 Weitwinkelgelenk in Mittelstellung, Fig. 2 wide-angle joint in the central position,
Fig. 3 Weitwinkelgelenk bei 90° in Arbeitsstellung mit eingesetzter, freibeweglicher Rundschale und eingesetzter kreisförmigen Hülse. Fig. 3 wide-angle joint at 90 ° in the working position with inserted, freely movable round shell and inserted circular sleeve.
Bei Fig. 1 zeigen beide Kreuzgelenke eine gleiche Abwinkelung, zusammen 90°, und ergeben ein homokinetisches Weitwinkelgelenk. Der Drehpunkt 11 des Kreuzgelenkes 10 ist gleichzeitig Mittelpunkt der Halbkugel 1.In Fig. 1, both universal joints have the same angle, together 90 °, and give a wide-angle constant velocity joint. The pivot point 11 of the universal joint 10 is also the center of the hemisphere 1 .
Die durch eine Muffe 6 verbundenen Rohrabschnitte 5, die einen beweglichen Sitz auf den Halbkugeln 1 haben, verbleiben bei jeder Bewegung der Kreuzgelenke 10 in Mittelstellung des umfassenden Hohlkörpers 12. Die bewegliche Rundscheibe 4, die mit ihren beiden kugelförmigen Zapfen 3 eine Verbindung zu den Halbkugeln 1 aufweist, verändert bei jedem Winkeleinschlag ihre Position derart, daß beide Kreuzgelenke 10 zur Mittellinie den gleichen Winkel bilden. Dabei ist es unwichtig, ob die Zapfen 3 sich an der Rundscheibe 4, oder an den Halbkugeln 1 befinden, wenn die Kugelfassung entsprechend angeordnet wird.The pipe sections 5 connected by a sleeve 6 , which have a movable seat on the hemispheres 1 , remain in the middle position of the encircling hollow body 12 with each movement of the universal joints 10 . The movable circular disc 4 , which has a connection to the hemispheres 1 with its two spherical pins 3 , changes its position with each angular movement in such a way that both universal joints 10 form the same angle with the center line. It is unimportant whether the pins 3 are on the circular disc 4 or on the hemispheres 1 if the spherical mount is arranged accordingly.
Die Kugellagerung 7 kann mit ihrem großen Durchmesser auch als einzige Lagerung eingesetzt werden.With its large diameter, the ball bearing 7 can also be used as the only bearing.
Bei Punkt 13 kann der entsprechende Schmiernippel eingeschraubt werden zur Versorgung der Lager 7 + 8, der Bohrung 2, der Zapfen 3, der Oberfläche der Halbkugel 1 und der beweglichen Rundscheibe 4.At point 13 the corresponding grease nipple can be screwed in to supply the bearings 7 + 8 , the bore 2 , the pin 3 , the surface of the hemisphere 1 and the movable circular disk 4 .
Bei Fig. 2 befinden sich die Kreuzgelenke 10 in Mittelstellung ohne Abwinkelung. Beim Lauf der Gelenkwelle dreht sich in dieser Stellung der gesamte Innenteil mit, erzeugt aber keine Reibungspunkte. Sobald eine Abwinkelung erfolgt, treten die Lager in Tätigkeit, und die Rotierung des Innenteils entfällt.In Fig. 2 there are the universal joints 10 in the center position without bending. When the PTO shaft runs, the entire inner part rotates in this position, but does not generate any friction points. As soon as it is bent, the bearings start to operate and there is no need to rotate the inner part.
Bei Fig. 3 ist die pilzartige Halbkugel durch die freibewegliche Rundschale 14 ersetzt. Die kugelförmige Abrundung 15 oder der Ring 16 drücken die Rundschale bei jedem Winkel in den Rohrabschnitt 5. Die kreisförmige Hülse 17 sitzt bei jedem Winkel in der Muffe 6 ein, ebenfalls sitzt stets die Rundscheibe 4 in der Hülse 17.In Fig. 3, the fungal hemisphere is replaced by the free moving circular shell 14. The spherical rounding 15 or the ring 16 press the round shell into the pipe section 5 at every angle. The circular sleeve 17 is seated in the sleeve 6 at every angle, and the circular disk 4 is also always seated in the sleeve 17 .
