Gleichlaufdrehgelenkkupplung mit Verschiebemöglichkeit Die Erfindung bezieht sich auf eine Gleichlaufdrehgelenkkupplung mit Verschiebemöglichkeit eines äußeren und eines inneren Gelenkkörpers relativ zueinander, deren Drehmomentübertragung durch Kugeln erfolgt, die in Längsrillen beider Gelenkkörper mit sich jeweils paarweise kreuzenden Längsmittellinien geführt und in einer Ebene in öffnungen eines in einer Zylinderfläche des äußeren Gelenkkörpers axial verschiebbaren Käfigs gehalten sind, der kugelschalenförmig ausgebildet und mit einem eine Relativverschiebung ge.genüber dem inneren Gelenkkörper zulassenden Abstand zu diesem angeordnet ist, nach Patent 1211871. Constant velocity joint coupling with displacement option The invention relates to a constant velocity universal joint coupling with displacement option of an outer and an inner joint body relative to one another, the torque transmission of which is carried out by balls, which are guided in longitudinal grooves of both joint bodies with longitudinal center lines crossing in pairs and in a plane in openings of one in a cylinder surface of the outer joint body are held axially displaceable cage, which is designed in the shape of a spherical shell and is arranged with a relative displacement ge.genüber the inner joint body allowing distance, according to patent 1 211 871.
Das Hauptpatent bezieht sich dabei sowohl auf solche Gelenke, bei denen die Führungsrillen für die Kugeln in demselben Gelenkkörper denselben Schrägungswinkel haben, als auch auf solche Gelenke, bei denen das Vorzeichen des Schrägungswinkels der Führungsrillen in demselben Gelenkkörper abwechselt. Unter den Gattungsbegriff fallen auch solche Gelenke, bei denen sich die Längsrillen wechselweise in entgegengesetzter Richtung keilförmig in Ebenen öffnen, welche die gemeinsame Achse der fluchtenden Wellen enthalten.The main patent relates to both such joints which the guide grooves for the balls in the same joint body have the same helix angle have, as well as those joints where the sign of the helix angle the guide grooves alternate in the same joint body. Under the generic term also include those joints in which the longitudinal grooves alternate in opposite directions Direction wedge-shaped open in planes, which are the common axis of the aligned Waves included.
Der Erfindung liegt die Aufgabe zugrunde, die Eigenschaften derartiger Verschiebegelenkkupplungen an den Endpunkten der Verschiebestrecke mö '-lichst weitgehend denen eines Festgelenkes anzunähern.The invention is based on the object of the properties of such Sliding joint couplings at the end points of the sliding distance as far as possible to approximate those of a fixed joint.
Zum Lösen dieser Aufgabe wird nach der Erfindung zunächst vorgesehen, daß die Außenfläche des inneren Gelenkkörpers zwei im Abstand von einer Kugelhauptebene liegende Kugelflächenzonen mit demselben Radius wie die Innenfläche des Käfigs aufweist, die so aneinander anschließen, daß der Querschnitt etwa die Gestalt eines Spitzbogens hat. Hierdurch wird an den Endpunkten der Verschiebestrecke eine flächenhafte Abstützung des Käfigs am inneren Gelenkkörper erreicht.To solve this problem, the invention initially provides that the outer surface of the inner joint body two at a distance from a main spherical plane has lying spherical surface zones with the same radius as the inner surface of the cage, which connect to one another in such a way that the cross-section roughly has the shape of a pointed arch Has. This provides extensive support at the end points of the displacement path of the cage on the inner joint body.
Ferner ist nach der Erfindung insbesondere als zusätzliche Maßnahme vorgesehen, daß die Enden der zylindrischen Innenfläche des äußeren Gelenkkörpers in an sich bekannter Weise in je eine Kugelflächenzone mit demselben Radius wie die äußere Ku-elfläche des Käfigs übergehen und daß die AnordnunC so getroffen ist, daß der Käfig, jeweils zugleich an einer dieser Kugelflächenzonen und an dem inneren Gelenkkörper zur Anlage kommt. Hierbei wird der Käfig in den Endlagen der Verschiebung zugleich am äußeren und am inneren Gelenkkörper abgestützt.Furthermore, according to the invention, it is particularly provided as an additional measure that the ends of the cylindrical inner surface of the outer joint body merge in a manner known per se into a spherical surface zone with the same radius as the outer spherical surface of the cage and that the arrangement is such that the cage, each at the same time comes to rest on one of these spherical surface zones and on the inner joint body. Here, the cage is supported in the end positions of the displacement at the same time on the outer and the inner joint body.
Die Erfindung wird im folgenden an Hand schematischer Zeichnungen an zwei Ausführungsbeispielen näher erläutert.The invention is described below with reference to schematic drawings explained in more detail using two exemplary embodiments.
F i g. 1 zeigt eine Gelekkupplung nach der Erfindung im Längsschnitt, wobei zur einfacheren Darstellung die Kugelrillen im inneren und äußeren Gelenkkörper in die Zeichenebene eingeschwenkt dargestellt sind; F i g. 2 ist ein Teil einer Abwicklung der Innenfläche des äußeren Gelenkkörpers und der Außenfläche des inneren Gelenkkörpers bei einer Ausführun,o"sform der Gelenkkupplung gemäß F i g. 1, bei der die Führun-srillen für die Ku-eln in demselben Gelenkkörper denselben Schrägungswinkel haben; F i g. 3 zeigt die entsprechende Abwicklung der Innenfläche des äußeren und der Außenfläche des inneren Gelenkkörpers bei einer Ausführungsform der Gelenkkupplung gemäß F i g. 1, bei der die benachbarten Län-srillen in jedem Gelenkkörper abwechselnd in entgegengesetzter Richtung steigen.F i g. 1 shows a joint coupling according to the invention in longitudinal section, the ball grooves in the inner and outer joint bodies being shown pivoted into the plane of the drawing for the sake of simplicity; F i g. 2 is a part of a development of the inner surface of the outer joint body and the outer surface of the inner joint body in an embodiment of the joint coupling according to FIG . 1, in which the guide grooves for the balls in the same joint body have the same helix angle Fig. 3 shows the corresponding development of the inner surface of the outer and the outer surface of the inner joint body in an embodiment of the joint coupling according to Fig. 1, in which the adjacent longitudinal grooves in each joint body rise alternately in opposite directions.
Bei der Gelenkkupplung gemäß F i g. 1 bat die Außenfläche des Käfigs 40 für die Kugeln 46 die Gestalt einer Kugelfläche mit dem Radius R um den Käfigmittelpunkt Z. Die zylindrische Innenfläche 41 des äußeren Gelenkkörpers 42 setzt sich an ihren Enden in je eine Kugelflächenzone 43 mit demselben Radius R wie die äußere Fläche des Käfigs, aber um die Punkte X und Y der Achse XZY des Zylinders fort. Die Innenfläche des Käfigs 40 hat ebenfalls die Gestalt einer Kugelfläche, und zwar mit dem Radius r um den Punkt Z. Der innere Gelenkkörper 45 hat im Querschnitt etwa die Gestalt eines Spitzbogens, der sich aus zwei Kugelflächenzonen 48 mit dem Radius r um zwei symmetrisch zum Punkt Z auf der Achse des inneren Gelenkkörpers liegende PunkteA und B zusammensetzt.In the case of the articulated coupling according to FIG . 1, the outer surface of the cage 40 for the balls 46 asking the shape of a spherical surface with the radius R around the cage center Z. The inner cylindrical surface 41 of the outer joint body 42 sits at its ends in a respective spherical surface zone 43 with the same radius R as the outer surface of the cage, but around points X and Y of the XZY axis of the cylinder. The inner surface of the cage 40 also has the shape of a spherical surface, with the radius r around the point Z. The inner joint body 45 has approximately the shape of a pointed arch in cross section, which is made up of two spherical surface zones 48 with the radius r by two symmetrical to the Point Z composes points A and B lying on the axis of the inner joint body.
Die Strecke X-Y ist die maximale Verschiebestrecke. Die rollende Bewegung erfolgt dabei maximal über eine Strecke der doppelten Länge des Abstandes der PunkteA und B. Am Ende der Verschiebestrecke kommt die äußere Kugelfläche des Käfigs 40 an den Kugelflächenzonen 43 des äußeren Gelenkkörpers 42 zur Anlage.The distance X-Y is the maximum displacement distance. The rolling motion takes place over a maximum distance of twice the length of the distance between points A. and B. At the end of the displacement distance, the outer spherical surface of the cage 40 comes on the spherical surface zones 43 of the outer joint body 42 to rest.
Bereits dann, wenn eine Kugelzone der Außenfläche des inneren Gelenkkörpers an der Kugelfläche des Käfigs zur Anlage kommt, nähert sich das Gelenk in seinen Eigenschaften denen eines Festgelenks. Wenn schließlich die kugelflächenförmige Außenfläche des Käfigs an den Kugelflächenzonen 43 des äußeren Gelenkkörpers anliegt, zeigt die Gelenkkupplung dasselbe Verhalten wie eine übliche Gleichlauf-Festgelenk-Kupplung, außer daß eine Verschiebemö-lichkeit in einer Richtung besteht.Already when a spherical zone of the outer surface of the inner joint body comes to rest on the spherical surface of the cage, the joint approaches in its Properties those of a fixed joint. When finally the spherical The outer surface of the cage rests against the spherical surface zones 43 of the outer joint body, the articulated coupling shows the same behavior as a common constant velocity fixed joint coupling, except that there is a possibility of shifting in one direction.
Dieses Verhalten liegt in gleicher Weise dann vor, wenn sich gemäß F i g. 2 die Kugeln 46 in Rillen 47 des äußeren Gelenkkörpers 42 und entsprechenden Rillen 49 des inneren Gelenkkörpers 45 bewegen, welche jeweils denselben Schrägungswinkel in demselben Gelenkkörper 42 bzw. 45 haben, oder wenn das Vorzeichen des Schrägungswinkels in demselben Gelenkkörper 42 bzw. 45 gemäß den mit Strichen bezeichneten Führungsrillen der F i g. 3 abwechselt. Die Ausführungsforin gemäß F i g. 2 wird gern bei Gelenkkupplungen benutzt, welche eine relativ geringe Drehzahl haben, bei denen aber ein relativ weiter Weg gewünscht ist. Die Ausführungsform gemäß F i g. 3 wird bei hohen Drehzahlen bevorzugt, da dann in bekannter Weise einem axialen Schub auf den Käfig vorgebeugt wird. Allerdings ist dann der Verschiebeweg durch die maximale Wanderstrecke der Kugeln in Umfangsrichtung gegeneinander begrenzt.This behavior is the same when, according to FIG. 2 move the balls 46 in grooves 47 of the outer joint body 42 and corresponding grooves 49 of the inner joint body 45, which each have the same helix angle in the same joint body 42 or 45, or if the sign of the helix angle in the same joint body 42 or 45 according to the The guide grooves of FIG . 3 alternates. The execution form according to FIG. 2 is often used for articulated couplings which have a relatively low speed, but where a relatively long distance is desired. The embodiment according to FIG. 3 is preferred at high speeds, since an axial thrust on the cage is then prevented in a known manner. However, the displacement path is then limited to one another by the maximum travel distance of the balls in the circumferential direction.
Es sei noch darauf hingewiesen, daß auch bei Gelenken, bei denen sich die Längsrillen wechselweise in entgegengesetzter Richtung keilförTnig öffnen, die beschriebene Kupplungsausbildung Anwendung finden kann. Auch bei solchen Gelenken kreuzen sich übrigens die Längsmittellinien der Führungsrillen paarweise, wenn sich auch nicht die Führungsrillen selbst kreuzen.It should also be pointed out that even with joints in which the longitudinal grooves alternately open wedge-shaped in the opposite direction, the described coupling training can be used. Even with such joints Incidentally, the longitudinal center lines of the guide grooves cross each other in pairs when also do not cross the guide grooves themselves.
