Description

Anhängerkupplung mit einem um ein Horizontalgelenk schwenkbaren Kupplungskopf Anhängerkupplungen mit einem um ein Horizontalgelenk in der Vertikalen schwenkbaren Kupplungskopf, bei denen der Kupplungskopf in seiner Mittelstellung durch Rastenscheiben oder Federn gehalten wird, sind bekannt. Bei diesen Ausführungen ist die erforderliche äußere Kraft zum Verschwenken des Kupplungskopfes nach abwärts geringer als für eine Bewegung nach aufwärts, weil das Eigengewicht des Kupplungskopfes das Abwärtsklappen unterstützt.Trailer coupling with a coupling head that can be pivoted about a horizontal joint Trailer hitches with a pivotable about a horizontal joint in the vertical Coupling head, in which the coupling head is in its central position by detent washers or springs are known. In these versions, the required external force for pivoting the coupling head downwards less than for an upward movement because the dead weight of the coupling head causes the downward folding supports.

Die Erfindung betrifft die Ausführung eines Vertikalgelenkes, welches den Vorzug der Kompensation des Gewichtes des Kupplungskopfes mit dem der hohen Lebensdauer und geringem Raumbedarf vereint.The invention relates to the execution of a vertical joint, which the advantage of compensating the weight of the coupling head with that of the high one Service life and low space requirements combined.

In der Zeichnung ist ein Beispiel der erfindungsgemäßen Ausführung dargestellt; es zeigt Fig. 1 die erfindungsgemäße Kupplung in Seitenansicht bei Mittelstellung, teilweise geschnitten, Fig. 2 die Kupplung mit nach abwärts geschwenktem Kupplungskopf, Fig. 3 das Vertikalgelenk im Schnitt in Blickrichtung A-B, Fig. 4 eine abgewandelte Ausführungsform des Gelenkes.In the drawing is an example of the embodiment according to the invention shown; it shows Fig. 1 the coupling according to the invention in side view Middle position, partially in section, Fig. 2 the coupling with pivoted downward Coupling head, Fig. 3 the vertical joint in section in viewing direction A-B, Fig. 4 a modified embodiment of the joint.

Der Kupplungskopf 1 ist in bekannter Weise durch einen horizontalen Gelenkbolzen 2 schwenkbar mit der Zugstange 3 verbunden. Am Kupplungskopf 1 ist an einen Querbolzen 4 eine Wippe 5 angelenkt, die sich in der Stellung der Fig. 1 gegen zwei Punkte a und b einer flächigen Anfräsung 6 der Zugstange 3 abstützt. Die Pressung wird durch ein federndes Mittel, hier beispielsweise durch ein Tellerfederpaket 7, erzielt, indem dieses gegen einen Bolzen 8 an der Wippe 5 drückt. Das Tellerfederpaket ist in einem Gehäuse 9 durch einen Zapfen 10 geführt, der mit seitlichem Bund auf einem im Kupplungskopf 1 gelagerten Querbolzen 11 lagert.The coupling head 1 is in a known manner by a horizontal The pivot pin 2 is pivotably connected to the tie rod 3. On the coupling head 1 is hinged to a cross bolt 4, a rocker 5, which is in the position of FIG. 1 is supported against two points a and b of a planar milling 6 of the tie rod 3. The pressing is carried out by a resilient means, here for example by a disk spring assembly 7, achieved by pressing against a bolt 8 on the rocker 5. The disc spring package is guided in a housing 9 by a pin 10 with a lateral collar a cross bolt 11 mounted in the coupling head 1.

Durch die verschiedenen Hebelarme der Angriffspunkte a und b an der Wippe 5 wird erreicht, daß das erforderliche Moment für die Aufwärtsbewegung des Gelenkes aus der Mittelstellung geringer ist, als für die Schwenkung aus der Mittelstellung nach unten Dadurch wird auf einfache Weise das Gewicht des Kupplungskopfes 1 kompensiert.Due to the different lever arms of the points of application a and b on the Rocker 5 is achieved that the required moment for the upward movement of the Joint from the central position is less than for the pivoting from the central position down The weight of the coupling head 1 is compensated for in a simple manner.

Die Anfräsung der Zugstange kann nach Fig. 1, 2 oder 4 konkav oder winkelig oder ähnlich ausgekehlt 2 sein. Hierdurch wird eine gegen Abnützung unempfindliche Mittelstellung des Kupplungskopfes gewährleistet.The milling of the tie rod can be concave or according to Fig. 1, 2 or 4 be angular or similarly fluted 2. This makes one that is insensitive to wear and tear Central position of the coupling head guaranteed.
