Description
Schnellkupplung zur Verbindung der Zapfwelle eines Schleppers mit der Antriebswelle einer Arbeitsmaschine Die Erfindung bezieht sich auf eine Schnellkupplung zur Verbindung der Zapfwelle eines Schleppers mit der Antriebswelle einer Arbeitsmaschine, bestehend aus einer Aufsteckhülse, die an ihrem Inneren ein dem Zapfwellenprofil entsprechendes Mehrkeilprofil aufweist.Quick coupling for connecting the PTO shaft of a tractor with the drive shaft of a work machine The invention relates to a quick coupling for connecting the power take-off shaft of a tractor to the drive shaft of a work machine, consisting of a push-on sleeve, which is attached to the PTO shaft profile on its interior has a corresponding multi-spline profile.
Es. ist bereits eine Schnellkupplung bekanntgeworden, die als Sperrelemente lose, in Bohrungen gelagerte Kugeln aufweist, die sich diametral gegenüberliegen, wobei die Gefahr besteht, daß die obenliegende Kugel beim Lösen der Kupplungsteile infolge ihres Eigengewichtes in der Sperrlage verbleibt und das Lösen der Kupplungsteile nicht gewährleistet.It. a quick coupling has already become known, which is used as a locking element has loose balls mounted in bores that are diametrically opposed to each other, there is a risk that the overhead ball when loosening the coupling parts remains in the blocking position due to its own weight and the loosening of the coupling parts not guaranteed.
Bei einer anderen Ausführung handelt es sich um eine Schnellkupplung, bei der mehrere Sperrbolzen an ihrem äußeren Ende mit je einem Querschlitz versehen sind, in die Führungsrippen eingreifen, die Bestandteil eines um die Aufsteckhülse drehbaren Ringes sind.Another version is a quick coupling, in which several locking bolts are each provided with a transverse slot at their outer end are engaged in the guide ribs, which are part of a around the slip-on sleeve rotatable ring are.
Diese Anordnung der Sperrbolzen und deren Sicherung im Kupplungskörper bedingt verhältnismäßig hohen Aufwand an Material und ist außerdem für den robusten Betrieb in der Landwirtschaft ungeeignet.This arrangement of the locking pins and their securing in the coupling body requires a relatively high cost of material and is also for the robust Unsuitable for use in agriculture.
Bei einer weiteren Zapfwellenkupplung wird als Sperrmittel gegen Axialkräfte ein Ring verwendet, der innen mit Erhebungen versehen ist. Der Ring ist in einem rohrförmigen Gelenkstück begrenzt drehbar und gegen axiale Kräfte abgestützt. Die Ausführung hat den Nachteil, daß die Nutzlänge für die axiale Abstützung gering ist und somit die Übertragung von Axialkräften wesentlich vermindert.Another PTO clutch acts as a locking means against axial forces a ring is used, which is provided with bumps on the inside. The ring is in one tubular joint piece rotatable to a limited extent and supported against axial forces. the Execution has the disadvantage that the useful length for the axial support is small and thus the transmission of axial forces is significantly reduced.
Erfindungsgemäß werden die Nachteile der bekannten Zapfwellenkupplungen dadurch vermieden, daß die Aufsteckhülse mit wenigstens zwei sich diametral gegenüberliegenden, radial angeordneten Querschlitzen versehen ist, in welchen je ein Sperrzapfen geführt wird, der mit einem um die Aufsteckhülse drehbaren Ring fest verbunden ist.According to the invention, the disadvantages of the known PTO clutches avoided by the fact that the push-on sleeve with at least two diametrically opposite, radially arranged transverse slots is provided, in each of which a locking pin is guided which is firmly connected to a ring rotatable around the push-on sleeve.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. 1 eine Schnellkupplung in Ansicht und Fig. 2 eine Schnellkupplung in Arbeitsstellung entsprechend der Schnittlinie.An exemplary embodiment of the invention is shown in the drawing. 1 shows a view of a quick coupling and FIG. 2 shows a quick coupling in working position according to the cutting line.
Auf der mit einem Mehrkeilprofil versehenen Zapfwelle 1 ist eine Aufsteckhülse 2 axial verschiebbar angeordnet, die in ihrem Inneren dem Zapfwellenprofil entsprechende Nuten aufweist. Die Aufsteckhülse 2 ist mit zwei Querschlitzen 3, die sich diametral gegenüberliegen und zur Führung der Sperrzapfen 4 dienen, versehen. Diese Sperrzapfen sind mit einem auf der Aufsteckhülse 2 aufgeschobenen Drehring 5 fest verbunden und mittels Körnerschlag gesichert. Zur Sicherung der Kupplung gegen Verdrehung ist eine Drehfeder 6 vorgesehen, die zwischen der Aufsteckhülse 2 und dem Drehring 5 angeordnet ist. Die Drehfeder 6 ist dabei in einer im Inneren des Drehringes 5 vorgesehenen Aussparung 7 geschützt untergebracht. Die axiale Festlegung der Kupplung erfolgt durch den Eingriff der Sperrzapfen 4 mit ihrem kugelförmig abgerundeten einen Zapfenende in eine Ringnut 8 der Zapfwelle 1.On the PTO shaft 1, which is provided with a multi-spline profile, there is a push-on sleeve 2 arranged axially displaceable, the corresponding inside the PTO profile Has grooves. The push-on sleeve 2 has two transverse slots 3, which are diametrically opposed opposite and serve to guide the locking pin 4, provided. These locking pins are firmly connected to a rotary ring 5 pushed onto the slip-on sleeve 2 and secured with a center punch. To secure the coupling against twisting a torsion spring 6 is provided between the push-on sleeve 2 and the rotating ring 5 is arranged. The torsion spring 6 is in one in the interior of the rotary ring 5 provided recess 7 housed protected. The axial fixing of the coupling takes place through the engagement of the locking pin 4 with its spherically rounded a pin end in an annular groove 8 of the power take-off shaft 1.
