Description
Kupplungsvorrichtung für Zugwagen und Anhänger mit einem in eine Gabel des Zugwagens einzusteckenden Kupplungsbolzen. Bei Kraftfahrzeugen besteht die Kupplungseinrichtung zumeist aus einer am Zugwagen befindlichen Gabel, die mit dem Kupplungsbügel bzw. der Kupplungsstange des Anhängewagens durch einen Bolzen verbunden wird. Die Abmessungen des Bolzens bzw. der Bohrung des Auges an der Kupplungsstange sind aber in ihren Durchmessern bei den verschiedenen Fabrikaten ungleich groß dimensioniert, so daß es vorkommt, daß der Bolzen durch das Auge nicht hindurchgesteckt werden kann bzw. der Durchmesser des Auges verhältnismäßig groß ist, was beim Fahren zu harten Stößen Veranlassung gibt, die das Kupplungsmaterial vorzeitig zerstören: idiit dem Gegenstand der Erfindung sollen diese übelstände in einfacher Weise behoben werden, und zwar durch eine neue Gestaltung des Kupplungsbolzens.Coupling device for towing vehicles and trailers with one in a fork of the towing vehicle to be inserted. The coupling device exists in motor vehicles mostly from a fork on the towing vehicle, which is connected to the coupling bracket or the coupling rod of the trailer is connected by a bolt. The dimensions of the bolt or the hole of the eye on the coupling rod are in their Diameters of different makes of unequal size, so that it happens that the bolt cannot be inserted through the eye or the diameter of the eye is relatively large, which leads to hard bumps when driving Gives cause that destroy the coupling material prematurely: idiit the object The invention is intended to remedy these inconveniences in a simple manner, namely through a new design of the coupling bolt.
Auf der Zeichnung ist -eine Anordnung in den Abb. i und z schematisch dargestellt. Der in die Kupplungsgabel a von unten einsteckbare Bolzen b ist zwischen den Gabelarmen von unten nach oben verjüngt, und zwar von dem größtvorkomnienden Bolzeadurchmesser c auf einen kleineren noch zulässigen Durchmesserd. Hierdurch wird zunächst bewirkt, däß die Kupplungsteile, wie Bolzen b und Kupplungsaugee, stets ineinanderpassen; des weiteren ergibt sich aber auch der große Vorteil, daß- die Kupplungsstange bzw. das Auge e dicht schließend im Bolzen ruht, wodurch die schädlichen, das Material vorzeitig zerstörenden Stöße beim Fahren und Anziehen vermieden werden.In the drawing, an arrangement in Figs. I and z is schematic shown. The bolt b which can be inserted from below into the coupling fork a is between the fork arms tapers from bottom to top, from the largest front Bolt diameter c to a smaller, still permissible diameter d. Through this is first effected that the coupling parts, such as bolts b and coupling eyes, always fit together; but there is also the great advantage that- the coupling rod or the eye e rests tightly in the bolt, whereby the damaging impacts, which prematurely destroy the material, when driving and putting on clothes be avoided.
