Description
Vorrichtung an einem Zugschlepper mit Kraftheber zum Ankuppeln von ein- oder zweiachsigen Anhängern Die vorliegende Erfindung betrifft eine Vorrichtung an einem Zugschlepper mit Kraftheber und Kupplungs- maul <RTI
ID="0001.0020"> zum Ankuppeln der Deichsel von ein- oder zwei achsigen Anhängern. Zum Ankuppeln eines Anhängers an einem Zugschlepper sind meist zwei Mann nötig, von denen der eine die Deichsel hält, während der andere den Schlepper rangiert.
Die Erfindung bezweckt eine Vorrichtung zu schaf- fen, mittels welcher das Ankuppeln vom Schleppersitz aus erfolgen kann, ohne dass eine Hilfskraft gebraucht wird.
Die erfindungsgemässe Vorrichtung ist dadurch ge- kennzeichnet dass am Kraftheber des Zugschleppers di rekt oder indirekt eine schlaufemförmige Fangvorrichtung zur Aufnahme der Anhänger-Deichsel vorgesehen ist, so dass die mit der Fangvorrichtung unterfahrene Deichsel durch Betätigen des Krafthebers so weit angehoben wer den kann,
dass beim Zurückfahren des Schleppers das Kupplungsauge der Deichsel in das Kupplungsmaul des Schleppers gleitet.
Nachfolgend wird anhand der Zeichnung ein Aus führungsbeispiel des Erfindungsgegenstandes beschrie- ben, und zwar an einem Schlepper, dessen Kraftheber mit einer Geräteschnellkupplung versehen ist.
Fig. 1 zeigt die Vorrichtung an einem Schlepper mit anzukuppelndem Anhänger, und Fig. 2 zeigt die Vorrichtung in Vorderansicht, in Richtung des Pfeiles A in Fig. 1.
Der Schlepper 3 ist auf seiner Rückseite mit einer Aufnahmekupplung 4 versehen. Das Kupplungsauge 11 an der Deichsel 10 des Anhängers 12 soll beim Zurück fahren des Schleppers 3 in das Maul 5 der Aufnahme kupplung 4 gleiten. Dazu muss aber zuerst die Deichsel 10 mit ihrem Kupplungsauge auf die Höhe der Aufnah- mekupplung 4 des Schleppers gehoben werden.
Zu die sem Zweck ist eine Fangvorrichtung vorgesehen. An der Schnellkupplung 6, die von dem Kraftheber 1, 2 des Schleppers 3 getragen wird, sind an den Stellen 8 zwei Kettenstücke 7 befestigt, die an ihren freien Enden durch ebnen Quersteg 9 miteinander verbunden sind.
Da die Deichsel 10 den Boden nicht berührt, ist es leicht mit der Fangvorrichtung bei gesenktem Krafthe- ber 1, 2 die Deichsel zu unterfahr. Das Ende der Deich sel liegt dann zwischen den zwei Kettenstücken 7 auf dein Quersteg 9.
Wird nun der Kraftheber hochgehoben, so wird damit auch, das Ende der Deichsel hochgehoben. Beim Zurückfahren, des Schleppers gleitet das Kupp lungsauge 11 der Deichsel in das Kupplungsmaul 5 des Schleppers. Die Verriegelung kann dann vom Schlepper fahrer mit der Hand erfolgen.
Anstatt der Kettenstücke 7 können auch Seilstücke verwendet werden. Auch eine andere schlaufenförmige Fangvorrichtung kann vorgesehen sein.
Ist am Schlepper keine Geräteschnellkupplung 6 vor handen, so kann die Vorrichtung auch direkt am Kraft heber angeordnet werden.
Device on a tractor with a power lift for coupling one or two-axle trailers. The present invention relates to a device on a tractor with a power lift and coupling jaw <RTI
ID = "0001.0020"> for coupling the drawbar of one or two axled trailers. To hitch a trailer to a tractor, two men are usually needed, one of whom holds the drawbar while the other maneuvers the tractor.
The aim of the invention is to create a device by means of which coupling can take place from the tractor seat without the need for an assistant.
The device according to the invention is characterized in that, directly or indirectly, a loop-shaped safety device for receiving the trailer drawbar is provided on the power lift of the tractor, so that the drawbar under which the safety device is driven can be raised by actuating the power lift,
that when the tractor moves back, the coupling eye of the drawbar slides into the coupling mouth of the tractor.
In the following, an exemplary embodiment of the subject matter of the invention is described with reference to the drawing, namely on a tractor whose power lift is provided with a quick coupling device.
1 shows the device on a tractor with a trailer to be coupled, and FIG. 2 shows the device in a front view, in the direction of arrow A in FIG.
The tractor 3 is provided with a female coupling 4 on its rear side. The coupling eye 11 on the drawbar 10 of the trailer 12 is to slide when driving back the tractor 3 in the mouth 5 of the receiving clutch 4. To do this, however, the drawbar 10 must first be raised with its coupling eye to the level of the receiving coupling 4 of the tractor.
A safety gear is provided for this purpose. On the quick coupling 6, which is carried by the power lift 1, 2 of the tractor 3, two pieces of chain 7 are attached at the points 8, which are connected to one another at their free ends by a flat crosspiece 9.
Since the drawbar 10 does not touch the ground, it is easy to drive under the drawbar with the safety gear when the power lift 1, 2 is lowered. The end of the drawbar then lies between the two pieces of chain 7 on your crossbar 9.
If the power lift is now raised, the end of the drawbar is also raised. When moving back, the tractor slides the coupling eye 11 of the drawbar in the coupling jaw 5 of the tractor. The tractor driver can then lock it manually.
Instead of the chain pieces 7, pieces of rope can also be used. Another loop-shaped catch device can also be provided.
If there is no quick coupling 6 on the tractor, the device can also be placed directly on the power lift.
