Description
Die Erfindung bezieht sich auf ein Kardangelenk, insbesondere für Kleinkraftfahrzeuge,
bei dem zwischen den beiden Wellenenden ein loses Kuppelglied vorgesehen ist.
Es ist bekannt, solche Kuppelglieder mit kreuzförmig zueinander verlaufenden Rillen
zu versehen. Man nat auch schon Kardangelenke hergestellt, bei denen das mittlere
Kuppelglied aus zwei ineinanderzuschieb'enden Teilen besteht.The invention relates to a universal joint, in particular for small motor vehicles, in which a loose coupling element is provided between the two shaft ends.
It is known to provide such coupling elements with cross-shaped grooves. Cardan joints have also been produced in which the middle coupling element consists of two parts that can be pushed into one another.
Demgegenüber besteht die Erfindung darin, daß die in dem losen Kuppelglied um 900 versetzt zueinander angeordneten Rillen zu Ausschnitten ausgebildet sind, in die plattenförmige Mitnehmer der Wellenenden hineinragen, die sich mit ihren kalottenförmigen Stützflächen auf einer in der Bohrung des Kuppelgliedes liegenden losen Kugel abstützen. In contrast, the invention consists in that the mutually arranged grooves offset in the loose coupling element 90 0 are formed into cut-outs extend into the plate-shaped carrier of the shaft ends, which rest with their cup-shaped supporting surfaces on a lying in the bore of the coupling element loose ball.
Durch diese Ausbildung wird erzielt, daß die Reibung, die durch den Achsdruck entsteht, verringert wird, indem sie sich im Innern auf der losen Kugel auswirkt. Andererseits ist der Flächendruck, der durch die Mitnehmerplatten entsteht, bei der Umdrehung infolge der verhältnismäßig breiten Ausführung der Mitnehmerflächen kleiner als bei sehr schmalen Gabeln, wie sie früher verwandt worden sind, so daß dadurch einem Verschleiß entgegengetreten wird.This training ensures that the friction caused by the axle pressure, is reduced by affecting the inside of the loose ball. on the other hand is the surface pressure created by the driver plates during rotation due to the relatively wide design of the driver surfaces smaller than in very narrow forks, as they were used earlier, so that this gives a Wear is countered.
Die Erfindung hat den wesentlichen technischen Fortschritt der vereinfachten Ausführung und daher der billigeren Herstellung. Es ist kein umständliches Drehstück notwendig. Die Schlitze und Platten lassen sich leichter einander anpassen, als wenn man gabelförmige Mitnehmer anwendet.The invention has the essential technical advancement of the simplified execution and therefore cheaper to manufacture. No cumbersome turning piece is necessary. The slots and plates are easier to match than if one were fork-shaped Driver applies.
Von Vorteil ist beim Erfindungsgegenstand ferner, daß die Rillen durch Deckflächen abdeckbar sind.Another advantage of the subject matter of the invention is that the grooves are formed by cover surfaces are coverable.
Die Erfindung läßt sich in verschiedener Weise ausführen. Sie ist in der Zeichnung beispielsweise in einer Ausführungsform veranschaulicht, und zwar zeigtThe invention can be carried out in various ways. She is in the drawing for example illustrated in one embodiment, namely FIG

Das Kardangelenk besteht aus einem kugelförmigen Verbindungsglieds, das für zwei zu kuppelnde Wellen b, c mit kreuzförmig zueinander liegenden Ausschnitten d, e versehen ist, die in der Kugeis nebeneinander liegen. In diese Kugelausschnitte £?,£ fassen segmentförmige Mitnehmer /, 0· der zu kuppelnden Wellenenden ein. Die segmentförmigen Mitnehmer sind plattenförmig ausgeführt und dienen durch ihren Eingriff in die Kugelausschnitte als Mitnehmerkeile. Die Mitnehmer f,g sind gegeneinander abgestützt, was entweder bei einfacher Ausführung unmittelbar geschehen kann, oder, wie in der Zeichnung veranschau-The cardan joint consists of a spherical connecting member which is provided with cross-shaped cutouts d, e for two shafts b, c to be coupled, which lie next to one another in the ball. In these spherical cutouts £?, £ enclose segment-shaped drivers /, 0 · of the shaft ends to be coupled. The segment-shaped drivers are plate-shaped and serve as driver wedges due to their engagement in the spherical cutouts. The drivers f, g are supported against each other, which can either happen directly with a simple design, or, as illustrated in the drawing
licht, besser unter Zwischenschaltung einer lose in eine zylindrische Bohrung h der Kugel α eingesetzten Kugel/, an der sich die abgerundeten, beispielsweise kalottenförmigen Stützflächen gt, Z1 der Mitnehmerplatten /, g abstützen.light, better with the interposition of a loosely inserted into a cylindrical bore h of the ball α ball /, on which the rounded, for example dome-shaped support surfaces g t , Z 1 of the driver plates /, g are supported .
Die zu verbindenden Wellen sind in axialer Richtung federnd gegeneinander in dem Kugelgelenk gehalten, indem mindestens der eine ίο Mitnehmerg" auf dem zu kuppelnden Wellenende c undrehbar, jedoch verschiebbar, beispielsweise mittels der Hülse k, geführt ist. Zwischen Wellenstumpf c und Mitnehmer g ist gleichachsig eine Feder I eingesetzt. Die Wellen b, c sind an ihrem anderen Ende, wo sie beispielsweise zum Antrieb dienen — beispielsweise kann die Welle & an dem Getriebe eines Motors angeschlossen sein, die Welle c an dem Getriebe des Hinterrades des Fahrzeuges -—, an sich unverschiebbar gelagert, jedoch durch das Kugelkardangelenk α nunmehr beweglich miteinander verbunden, so daß sie sich in einem Winkel zueinander einstellen können.The shafts to be connected are held against each other in the axial direction resiliently in the ball joint, by at least the "non-rotatably on the c to be coupled to the shaft end, but slidably, k is an ίο Mitnehmerg for example by means of the sleeve, is guided. C intermediate stub shaft and the carrier is g equiaxed a spring I. The shafts b, c are at their other end, where they are used, for example, to drive - for example, the shaft & can be connected to the gearbox of a motor, the shaft c to the gearbox of the rear wheel of the vehicle - on mounted immovably, but now movably connected to one another by the spherical cardan joint α, so that they can be set at an angle to one another.
Die Mitnehmerplatten /, g sind so ausgeführt,
daß ein genügender Spielraum m in den Ausschnitten vorhanden ist, um einen genügenden
Winkelausschlag der Wellen zueinander zu gestatten.
Die Mitnahme der Hülse k des Mitnehmers g mittels der Welle c erfolgt beispielsweise
durch die Nutenkeile η (s. Abb. 5).The driver plates /, g are designed so that there is sufficient play m in the cutouts to allow a sufficient angular deflection of the shafts to each other.
The driving of the sleeve k of the driver g by means of the shaft c takes place, for example, by the keyways η (see Fig. 5).
Die Wellenenden bzw. die Mitnehmer f, g sind an der Außenseite der Kugel mit seitlichen Deckflächen ο versehen, welche ebenfalls segmentförmig ausgebildet sind, und durch die die Kugelausschnitte einigermaßen verdeckt werden, um das Eindringen von Staub und Schmutz zu verhindern.The shaft ends or the drivers f, g are provided on the outside of the ball with lateral cover surfaces ο , which are also segment-shaped, and by which the ball cutouts are covered to some extent in order to prevent the ingress of dust and dirt.
