Description

Schlepper mit zwischen zwei Lochschienen gelagerter Anhängerkupplung und Dreipunktanbauvorrichtung Die Erfindung bezieht sich auf einen Schlepper mit zwischen zwei Lochschienen gelagerter Anhängerkupplung und Dreipunktanbauvorrichtung. Es ist schon bekanntgemacht, den Tragbock mittels Steckbolzen am Schlepper zu lagern. Auch hat man schon vorgeschlagen, den Kupplungskopf in senkrechter Ebene schwenkbar an seinem Träger anzuordnen. Dennoch bereitet bei Ackerschleppern mit Dreipunktanbauvorrichtung der Anschluß von deren oberen Lenker im Bereich eines die Erzielung einer maximalen Zugkraft ermöglichenden Punktes am Schlepper erhebliche Schwierigkeiten. Die Erfindung hat sich zum Ziel gesetzt, diesen übelstand unter Zurückgreifen auf die normalerweise gegebenen konstruktiven Möglichkeiten zu beheben. Sie schafft eine Anordnung, die infolge ihrer neuartigen Ausgestaltung in einfachster und daher auch wirtschaftlich vorteilhaftester Weise besonders gute Betriebseigenschaften bei der übertragung der Zugkraft aufweist.Tractor with a trailer coupling mounted between two perforated rails and three-point hitch The invention relates to a tractor with Trailer coupling and three-point hitch mounted between two perforated rails. It is already known to mount the trestle on the tractor by means of socket pins. It has also been proposed to pivot the coupling head in a vertical plane to be arranged on its carrier. Nevertheless, it prepares for tractors with three-point hitch the connection of their upper link in the area of the achievement of a maximum Traction enabling point on the tractor considerable difficulties. The invention has set itself the goal of addressing this malady by resorting to normally to fix given constructive possibilities. She creates an arrangement that due to their novel design in the simplest and therefore also economical most advantageously, particularly good operating properties during transmission the tensile force.

Diese Vorteile werden erfindungsgemäß dadurch erzielt, daß der Tragbock der Anhängerkupplung um einen Steckbolzen in senkrechter Ebene schwenkbar und in verschiedenen Stellungen an den Lochschienen feststellbar ist und an der beim Verschwenken aus der Anhängestellung entgegen der Fahrtrichtung weisenden Seite eine oder mehrere Lochschienen für den Anschluß des oberen Lenkers des Dreipunktgestänges hat.These advantages are achieved according to the invention in that the support bracket the trailer hitch can be pivoted about a socket pin in a vertical plane and in different positions on the perforated rails can be determined and when pivoting one or more of the side facing opposite the direction of travel from the attachment Has perforated rails for connecting the upper link of the three-point linkage.

Die Verschwenkbarkeit des Kupplungstragbockes gestattet es, den Punkt des Schleppers von maximaler Zugkraftübertragung auch zur Anlenkung des Dreipunktgestänges heranzuziehen. Hierzu wird lediglich der Tragbock der Anhängerkupplung in eine unwirksame Stellung verschwenkt. In dieser Stellung dient dann der Tragbock als Anschlußelement für den oberen Lenker des Dreipunktgestänges.The pivotability of the coupling support bracket allows the point of the tractor of maximum tractive power transmission also for the articulation of the three-point linkage to use. For this purpose, only the support bracket of the trailer coupling is in an ineffective Swiveled position. In this position, the support bracket then serves as a connection element for the upper link of the three-point linkage.

Gemäß einem weiteren Merkmal der Erfindung können die Lochschienen des Schleppers eine den Tragbock in die Senkrechtstellung überragende Breite haben, wobei der überragende Teil die Lochreihe zum Anschluß des oberen Lenkers des Dreipunktgestänges trägt.According to a further feature of the invention, the perforated rails of the tractor have a width that protrudes beyond the support frame in the vertical position, the protruding part is the row of holes for connecting the upper link of the three-point linkage wearing.

In der Zeichnung ist die Erfindung beispielsweise dargestellt, und zwar zeigt Fig. 1 das hintere Ende eines Schleppers mit Anhängerkupplung in Arbeitsstellung, Fig. 2 eine der Fig. 1 entsprechende Darstellung mit an den Schlepper angeschlossenem oberem Lenker des Dreipunktgestänges und Fig. 3 eine Draufsicht auf die Anhängerkupplung in einer Fig. 1 entsprechenden Darstellung.In the drawing, the invention is shown as an example, namely Fig. 1 shows the rear end of a tractor with trailer coupling in the working position, Fig. 2 shows a representation corresponding to Fig. 1 with the upper link of the three-point linkage connected to the tractor, and Fig. 3 is a plan view on the trailer coupling in a representation corresponding to FIG. 1.

An der Rückseite des mit 1 bezeichneten Getriebegehäuses eines Schleppers sind zwei Lochschienen2 befestigt, die Bohrungen 3 aufweisen. Zwischen den beiden Lochschienen2 ist der Tragbock4 der insgesamt mit 5 bezeichneten Anhängerkupplung mittels zweier durch die Bohrungen 3 geführter Steckbolzen6 befestigt. Nach Lösen des die Bohrung3' durchsetzenden Steckbolzens kann die Anhängerkupplung 5 um den Steckbolzen in der Bohrung 3 in Pfeilrichtung 7 verschwenkt werden. Die Lochschienen 2 sind etwa auf die Breite des Tragbockes 4 verbreitert und weisen eine weitere mit 8 bezeichnete Bohrung auf, durch welche nach Hochschwenken des Tragbockes 4 im Sinne des Pfeiles 7 der vorher die Bohrung 3' durchsetzende Steckbolzen geführt werden kann.Two perforated rails 2, which have bores 3 , are attached to the rear of the transmission housing of a tractor designated by 1. Between the two perforated rails 2, the support bracket 4 of the trailer coupling, designated as a whole by 5, is fastened by means of two socket pins 6 guided through the bores 3. After dissolving the Bohrung3 the 'passing through the socket pin 5, the trailer hitch can be pivoted around the lock pin in the bore 3 in the arrow direction. 7 The perforated rails 2 are widened approximately to the width of the support bracket 4 and have a further bore denoted by 8 through which, after pivoting the support bracket 4 upwards in the direction of arrow 7, the socket pin which previously penetrated the bore 3 ' can be passed.

An seiner in Fig. 1 unteren Seite trägt der Tragbock 4 zwei Lochschienen 9, die bei in die in Fig. 2 wiedergegebene Stellung verschwenkter Anhängerkupplung entgegen der Fahrtrichtung des Schleppers weisen und in deren Bohrungen 10 der mit 11 angedeutete obere Lenker eines Dreipunktgestänges angeschlossen werden kann. Diese Lochschienen 9 können sich über die ganze Länge des Tragbockes 4 erstrecken, um nach Bedarf besonderen Anhängeverhältnissen Rechnung zu tragen. Dieser Tatsache ist in den Fig. 1 und 2 durch teilweise punktierte Darstellung der Lochschiene 9 Rechnung getragen.On its lower side in Fig. 1 , the support bracket 4 carries two perforated rails 9, which point against the direction of travel of the tractor when the trailer hitch is pivoted into the position shown in Fig. 2 and in whose bores 10 the upper link indicated by 11 of a three-point linkage can be connected . These perforated rails 9 can extend over the entire length of the support bracket 4 in order to take into account special attachment conditions as required. This fact is taken into account in FIGS. 1 and 2 by the partially dotted representation of the perforated rail 9.
