Description

Kupplung für Lastkraftwagen-Anhänger mit gegabelter Deichsel. Die Erfindung bezieht sich auf Kupplungen für Lastkraftwagen-Anhänger mit einer gegabelten Deichsel, deren Arme miteinander und mit dem Anhänger gelenkig verbunden sind und je aus zwei gelenkig miteinander verbundenen Gliedern bestehen. Die Erfindung besteht darin, daß an einem der vorderen Glieder der Deichsel ein Kupplungsbolzen gelagert ist, der beim Übergang der Kupplung in die Fahrstellung in das analere vordere Glied eingreift. Durch diese Anordnung wird erreicht, daß die Ausschaltung der Gelenke der Deichsel beim Anfahren des Fahrzeuges selbsttätig erfolgt, so daß das Kuppeln zweier Fahrzeuge rasch und gefahrlos erfolgen kann.Coupling for truck trailers with forked drawbar. the The invention relates to couplings for truck trailers with a forked Drawbar whose arms are articulated with each other and with the trailer and each consist of two articulated links. The invention exists in that a coupling pin is mounted on one of the front links of the drawbar is that when the clutch changes to the driving position in the anal front link intervenes. This arrangement ensures that the joints are eliminated the drawbar takes place automatically when the vehicle starts, so that the coupling two vehicles can be done quickly and safely.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht, und zwar zeigt Abb. i eine Oberansicht der in der Fahrstellung befindlichen Kupplung, teilweise im Schnitt, Abb. 2 die zugehörige Seitenansicht, einige Teile sind weggebrochen, Abb. 3 in größerem Maßstäbe den Schnitt nach 3-3 der Abb. i, von links gesehen, und Abb. 4 eine Oberansicht der Kupplung bei einer Stellung, die sie vor dem Kuppeln der nicht in einer Richtung stehenden Fahrzeuge einnimmt.An exemplary embodiment of the invention is illustrated in the drawing, namely Fig. i shows a top view of the clutch in the driving position, partly in section, Fig. 2 the associated side view, some parts are broken away, Fig. 3 on a larger scale the section according to 3-3 of Fig. I, seen from the left, and Fig. 4 is a top view of the coupling in the position it will be prior to coupling which does not occupy vehicles that are not in one direction.

Die Kupplung besitzt eine gegabelte Deichsel mit fünf Gelenken a, b, c, d und e. Diese Gelenke gestatten es, die Kupplung in einer Ebene beliebig zu schwenken und ihr somit jede gewünschte Lage zu geben.The coupling has a forked drawbar with five joints a, b, c, d and e. These joints allow the coupling to be pivoted as desired in one plane and thus to give it any desired position.

Soll ein Anhänger F mit einem Motorwagen gekuppelt werden, so ist es nur erforderlich, daß der Motorwagen ungefähr bis in die Nähe der Protzöse g des Anhängers heranfährt, da die Protzöse durch Schwenken der Kupplung ohne weiteres in diejenige Lage gebracht werden kann, in welcher der Kupplungsbolzen des Motorwagens in Eingriff mit der Protzöse g treten kann. Ist die Kupplung der beiden Fahrzeuge durch Einführen des Kupplungsbolzens in die Protzöse erfolgt, so kann die Fahrstellung (Abb. i) der beiden Kupplungsarme h und i durch Anziehen des Motorwagens herbeigeführt werden. Im vorderen Gliede des Kupplungsarmes i ist ein Bolzen k in senkrechter Richtung verschiebbar gelagert. Dieser Bolzen ist dazu bestimmt, unter der Wirkung einer Feder n (Abb. 3) in eine Bohrung m (Abb. 3 .und 4) des vorderen Gliedes des Kupplungsarmes h einzugreifen; er steht in gelenkiger Verbindung mit einem Handhebel p, mittels dessen er außer Eingriff mit der Bohrung m gebracht wird, wenn die Kupplung verschwenkt werden soll. Wird dagegen die Kupplung aus der verschwenkten Lage (Abb.4) beim Anziehen des Motorwagens gestreckt, d. h. in ihre Fahrstellung gebracht, so wird der Bolzen k durch eine der beiden an dem vorderen Gliede des Kupplungsarmes h vorgesehenen Schrägflächen y (Abb. 3) entgegen der Wirkung der Feder n emporgedrückt. Bei erfolgter Streckung der Kupplung springt er jedoch wieder in die Bohrungm ein, so daß die Kupplung ein starres System bildet. Um zu verhindern, daß die Kupplungsarme h, i beim Verschwenken nach innen durchknicken, sind ihre beiden Glieder in der Nähe der Gelenke b, c mit Anschlagflächen s versehen.If a trailer F is to be coupled to a motor vehicle, it is only necessary that the motor vehicle drives approximately up to the vicinity of the prominent eye g of the trailer, since the prominent eye can easily be brought into the position in which the Coupling bolt of the motor vehicle can come into engagement with the ostentatious eye g. If the coupling of the two vehicles is done by inserting the coupling bolt into the ostentatious eyelet, the driving position (Fig. I) of the two coupling arms h and i can be brought about by pulling the motor vehicle. In the front link of the coupling arm i, a bolt k is mounted so as to be displaceable in the vertical direction. This bolt is designed to engage, under the action of a spring n (Fig. 3), in a hole m (Fig. 3 and 4) in the front link of the coupling arm h; it is in an articulated connection with a hand lever p, by means of which it is disengaged from the bore m when the coupling is to be pivoted. If, on the other hand, the coupling is stretched out of the pivoted position (Fig. 4) when the motor vehicle is pulled, i.e. brought into its driving position, the bolt k is countered by one of the two inclined surfaces y (Fig. 3) provided on the front link of the coupling arm h pushed up by the action of the spring n. When the coupling has been stretched, however, it jumps back into the borehole, so that the coupling forms a rigid system. In order to prevent the coupling arms h, i from buckling inward when pivoting, their two links are provided with stop surfaces s near the joints b, c.
