Derartige mechanische und hydraulische Kupplungen sind aus dem Stand der Technik bekannt. Es ist jedoch bisher nicht bekannt, eine Einrichtung vorzusehen, durch welche eine automatische Kupplung der hydraulischen Systeme erfolgt.Such mechanical and hydraulic couplings are from the state known in the art. However, it is not yet known an establishment to provide through which an automatic clutch of the hydraulic Systems.

Nachstehend ist anhand der Fig.2 die erfindungsgemäße Kupplungseinrichtung, durch welche eine automatische Kupplung der hydraulischen Systeme bewirkt werden kann, erläutert:Below is the coupling device according to the invention with reference to FIG. 2, through which an automatic coupling of the hydraulic systems can be explained:

An der am Traktor 1 vorgesehenen Tragkonsole 11 ist eine erste Kupplungsplatte 31 starr befestigt. An diese Kupplungsplatte 31 sind zum hydraulischen System des Traktors 1 führende Leitungen 32 angeschlossen. An der Tragkonsole 11 ist zudem ein die Kupplungsplatte 31 U-förmig umschließendes Stellelement 4 vorgesehen, welches mittels eines hydraulischen Stellzylinders 41 gegenüber der Kupplungsplatte 31 vertikal verschiebbar ist. An der Tragkonsole 11 befindet sich weiters eine von dieser quer abragende Führungsplatte 12, welche von einer am Stellelement 4 vorgesehenen Lasche 13 umschlossen wird. Das Stellelement 4 ist an seinem oberen Ende mit zwei Fanghaken 42 ausgebildet, welche mit Führungsschlitzen 43 ausgebildet sind. An der Kupplungsplatte 31 ist weiters ein Bolzen 44 befestigt, welcher das Stellelement 4 in zwei Schlitzen 45 durchsetzt und an welchem ein Rasthaken 46 verschwenkbar gelagert ist. Der Rasthaken 46 ist mit einer Führungsfläche 47 ausgebildet, welcher ein am Stellelement 4 angeordneter Stellbolzen 48 zugeordnet ist. Weiters ragen von der Innenseite des Stellelementes 4 vier Bolzen 49 ab.
Das Stellelement 4 ist mittels des Stellzylinders 41 höhenverstellbar. Die Führung des Stellelementes 4 erfolgt durch die Schlitze 45, welche vom Bolzen 44 durchsetzt sind, sowie durch die Lasche 13, welche längs der Führungsplatte 12 gleitet.A first coupling plate 31 is rigidly attached to the support bracket 11 provided on the tractor 1. Lines 32 leading to the hydraulic system of the tractor 1 are connected to this coupling plate 31. On the support bracket 11, an actuating element 4, which surrounds the coupling plate 31 in a U-shape, is also provided, which can be displaced vertically relative to the coupling plate 31 by means of a hydraulic actuating cylinder 41. On the support bracket 11 there is also a guide plate 12 which projects transversely therefrom and is enclosed by a tab 13 provided on the actuating element 4. The actuating element 4 is formed at its upper end with two catch hooks 42, which are formed with guide slots 43. On the coupling plate 31, a bolt 44 is also fastened, which passes through the adjusting element 4 in two slots 45 and on which a latching hook 46 is pivotally mounted. The latching hook 46 is formed with a guide surface 47 to which an adjusting bolt 48 arranged on the adjusting element 4 is assigned. Furthermore, four bolts 49 protrude from the inside of the actuating element 4.
The adjusting element 4 can be adjusted in height by means of the adjusting cylinder 41. The actuating element 4 is guided through the slots 45, which are penetrated by the bolt 44, and through the tab 13, which slides along the guide plate 12.

Zudem ist an der Kupplungsplatte 31 ein entgegen der Wirkung einer Rückstellfeder in seine Offenlage verstellbarer Verschlußdeckel 70 gelagert. Die Verschwenkung des Verschlußdeckels 70 erfolgt gleichfalls durch das Stellelement 4. In addition, on the clutch plate 31 is against the action of a return spring adjustable cover 70 stored in its open position. The Pivoting the closure cover 70 is also done by the actuator 4th

Die der Kupplungsplatte 31 des Tragfahrzeuges 1 am der Ladegerät 2 zugeordnete Kupplungsplatte 51 ist an einem Träger 5 angeordnet. Von dieser Kupplungsplatte 51 gehen hydraulische Leitungen 52 ab, welche zum hydraulischen System des Ladegerätes 2 führen. Die Kupplungsplatte 51 ist weiters mit einem quer abragenden Bolzen 53 ausgebildet, durch welchen sie am Träger 5 um eine angenähert horizontale Achse verschwenkbar gelagert ist. Die Verschwenkbarkeit wird durch einen am Träger 5 vorgesehenen Bolzen 56 begrenzt. An der Konsole 21 des Ladegerätes 2 ist ein Schwingarm 6 gelagert, welcher um eine angenähert horizontal ausgerichtete Achse 61 verschwenkbar ist. An den Schwingarm 6 ist eine Stellstange 62 angelenkt, welche in ihrer wirksamen Länge einstellbar ist und welche von einer Schraubendruckfeder 63 umgeben ist. Der Träger 5 ist mittels einer Lasche 54 längs des Schwingarmes 6 verschiebbar, wobei er mittels einer Bremseinrichtung 55 in der jeweiligen Lage verbleibt.The one assigned to the coupling plate 31 of the carrier vehicle 1 on the charger 2 Coupling plate 51 is arranged on a carrier 5. Of this Coupling plate 51 go off hydraulic lines 52, which for hydraulic Lead charger 2 system. The clutch plate 51 is further formed with a transversely protruding bolt 53 through which they mounted on the support 5 so as to be pivotable about an approximately horizontal axis is. The pivotability is provided by a bolt provided on the support 5 56 limited. On the bracket 21 of the charger 2 is a swing arm 6 mounted, which is pivotable about an approximately horizontally aligned axis 61 is. An actuating rod 62 is articulated to the swing arm 6, which its effective length is adjustable and which by a helical compression spring 63 is surrounded. The carrier 5 is longitudinal by means of a tab 54 of the swing arm 6 slidably, it by means of a braking device 55 remains in the respective position.

Die für den Kupplungsvorgang erforderliche Abwärtsbewegung der Kupplungsplatte 51 mittels des Stellelementes 4 wird dadurch ermöglicht, daß der Schwingarm 6 um den Bolzen 61 entgegen der Wirkung der Druckfeder 63 verschwenkbar ist, daß weiters der Träger 5 für die Kupplungsplatte 51 mittels der Traglasche 54 längs des Schwingarmes 6 verschiebbar ist und daß die Kupplungsplatte 51 im Träger 5 um den Bolzen 53 verschwenkbar gelagert ist. Da die wirksame Länge der Stellstange 62 mittels einer Stellmutter einstellbar ist, ist das Ausmaß der Schwenkbewegung des Schwingarmes 6 einstellbar.The downward movement of the clutch plate required for the clutch process 51 by means of the actuator 4 is made possible that the Swing arm 6 around the pin 61 against the action of the compression spring 63 is pivotable that the carrier 5 for the clutch plate 51 by means of the support bracket 54 is displaceable along the swing arm 6 and that the coupling plate 51 is pivotally mounted in the carrier 5 about the bolt 53 is. Since the effective length of the adjusting rod 62 by means of an adjusting nut is adjustable, the extent of the pivoting movement of the swing arm 6 adjustable.

Die Wirkungsweise dieser Kupplungseinrichtung ist nachstehend anhand der Fig.3 bis 3e erläutert:
In der Ausgangslage, welche in Fig.3 dargestellt ist, ist die Kupplungsplatte 31 des Traktors 1 durch den Abschlußdeckel 70 abgedeckt und befindet sich die Stelleinrichtung 4 in ihrer untersten Lage.
Sobald die hydraulischen Systeme des Traktors 1 und des Ladegerätes 2 miteinander gekuppelt werden sollen, wird das Stellelement 4 mittels des Stellzylinders 41 aufwärts bewegt. Hierdurch wird der Verschlußdeckel 70 mittels an diesem seitlich angeordneter Steuerbolzen 71, welche in seitlich am Stellelement 4 vorgesehene Kulissenführungen 72 einragen, entgegen der Wirkung seiner Schließfeder im Gegenuhrzeigersinn in seine vertikale Lage verschwenkt, wobei er durch die Kulissenführungen 72 in dieser Lage gehalten wird. Zudem wird durch den Stellbolzen 48, welche auf die Führungsfläche 47 aufläuft, der Rasthebel 46 um den Bolzen 44 im Gegenuhrzeigersinn verschwenkt, wodurch dessen Führungsfläche 47 angenähert vertikal ausgerichtet ist.The operation of this coupling device is explained below with reference to Figures 3 to 3e:
In the starting position, which is shown in Figure 3, the clutch plate 31 of the tractor 1 is covered by the end cover 70 and the actuating device 4 is in its lowest position.
As soon as the hydraulic systems of the tractor 1 and the charger 2 are to be coupled to one another, the actuating element 4 is moved upwards by means of the actuating cylinder 41. As a result, the closure cover 70 is pivoted counterclockwise into its vertical position against the action of its closing spring by means of control bolts 71 which are arranged on the side of the latter and which protrude into link guides 72 provided on the actuating element 4, and is held in this position by the link guides 72. In addition, the locking pin 46 is pivoted about the pin 44 in the counterclockwise direction by the adjusting bolt 48, which runs onto the guide surface 47, whereby its guide surface 47 is approximately vertically aligned.

In dieser Lage, welche in Fig.3a dargestellt ist, wird der Traktor 1 so zum Ladegerät 2 hin bewegt, daß sich die Kupplungsplatten 31 und 51 vertikal übereinander befinden und die Fanghaken 42 über die seitlich der Kupplungsplatte 51 ausragenden beiden Enden des Tragbolzen 53 gelangen, wodurch sich diese Enden innerhalb der Schlitze 43 befinden. Diese Lage ist in Fig.3b dargestellt.In this position, which is shown in FIG. 3a, the tractor 1 thus becomes a charger 2 moves that the clutch plates 31 and 51 vertically one above the other are located and the catch hook 42 on the side of the clutch plate 51 protrude two ends of the support bolt 53, which causes these ends are located within the slots 43. This situation is shown in Fig.3b.

Hierauf wird das Stellelement 4 mittels des Stellzylinders 41 abwärts bewegt, wobei sich der Stellbolzen 48 längs des vertikal verlaufenden Abschnittes der Führungsfläche 47 des Rasthakens 46 bewegt, wodurch dieser in seiner Lage verbleibt. Diese Lage ist in Fig. 3c dargestellt. Durch eine weitere Bewegung kommt die Unterseite der Kupplungsplatte 51 auf der Oberseite der Kupplungsplatte 31 zur Auflage, wodurch die beiden hydraulischen Systeme miteinander gekuppelt sind.The actuating element 4 is then moved downwards by means of the actuating cylinder 41, the adjusting pin 48 along the vertical portion of the Guide surface 47 of the locking hook 46 moves, causing this in its position remains. This situation is shown in Fig. 3c. By another move comes the bottom of the clutch plate 51 on top of the clutch plate 31 to support, whereby the two hydraulic systems together are coupled.

Durch den Bolzen 56 wird das Ausschwenken der Kupplungsplatte 51 begrenzt. Bei der Abwärtsbewegung des Stellelementes 4 kommen weiters die Bolzen 49 an die Oberseite der Kupplungsplatte 51 zur Anlage, wodurch diese gegenüber der Kupplungsplatte 31, an welche sie durch das Stellelement 4 zur Anlage gebracht wird, parallel ausgerichtet wird.The pivoting out of the coupling plate 51 is limited by the bolt 56. With the downward movement of the control element 4 also come Bolt 49 to the top of the clutch plate 51 to the system, causing this opposite the clutch plate 31, to which it is actuated by the actuating element 4 brought to the plant, is aligned in parallel.

Im letzten Teil der Abwärtsbewegung des Stellelementes 4 kommt der Stellbolzen 48 an einen Vorsprung 47a der Führungsfläche 47 des Rasthakens 46 zur Anlage, wodurch der Rasthaken 46 im Uhrzeigersinn verschwenkt wird. Durch diese Verschwenkung wird der Rasthaken 46 über den Tragbolzen 53 verschwenkt, wodurch die beiden Kupplungsplatten 31 und 51 mittels des Rasthakens 46 in ihrer gekuppelten Lage verriegelt sind. Diese Lage ist in Fig.3d dargestellt.
Selbst dann, wenn in weiterer Folge das Stellelement 4 aufgrund von Leckagen im hydraulischen System etwas nach aufwärts verschoben wird, wie dies in Fig.3e dargestellt ist, verbleibt der Rasthaken 46 in seiner den Tragbolzen 53 verriegelnden Stellung, wodurch die Kupplung der hydraulischen Systeme gesichert ist. Nachdem die Kupplung der hydraulischen Systeme erfolgt ist, wird das Ladegerät 2 an den Traktor 1 mechanisch angekuppelt und in seiner Lage verriegelt.In the last part of the downward movement of the actuating element 4, the actuating pin 48 comes to rest against a projection 47a of the guide surface 47 of the latching hook 46, as a result of which the latching hook 46 is pivoted clockwise. As a result of this pivoting, the latching hook 46 is pivoted over the supporting bolt 53, as a result of which the two coupling plates 31 and 51 are locked in their coupled position by means of the latching hook 46. This situation is shown in Fig.3d.
Even if the actuating element 4 is subsequently moved upwards somewhat due to leakages in the hydraulic system, as shown in FIG. 3e, the latching hook 46 remains in its position locking the supporting bolt 53, thereby securing the coupling of the hydraulic systems is. After the hydraulic systems have been coupled, the charger 2 is mechanically coupled to the tractor 1 and locked in position.

Sobald das Ladegerät 2 vom Traktor 1 wieder entfernt werden soll, erfolgt zuerst mittels der hydraulischen Systeme die mechanische Entkupplung. In der Folge werden die beiden Kupplungsplatten 31 und 51 dadurch voneinander entkuppelt, daß das Stellelement 4 mittels des Stellzylinders 41 aufwärts verschoben wird. Hierdurch wird der Rasthaken 46 durch den mit der Führungsfläche 47 zusammen wirkenden Stellbolzen 48 im Gegenuhrzeigersinn verschwenkt, wodurch die beiden Enden des Tragbolzens 53 freigegeben werden. Hierdurch kann durch eine weitere Aufwärtsbewegung des Stellelementes 4 der Träger 5 für die Kupplungsplatte 51 durch das Stellelement 4 angehoben werden, wodurch die Kupplungsplatte 51 von der Kupplungsplatte 31 gelöst wird. Hierbei gleitet der Träger 5 für die Kupplungsplatte 51 längs des Schwingarmes 6 aufwärts. Da in der Folge die freien Enden des Tragbolzens 53 von den Fanghaken 42 freigegeben werden, kann der Traktor 1 vom Ladegerät 2 vollständig wegbewegt werden.
Aufgrund der Bremseinrichtung 55 verbleibt der Träger 5 in derjenigen Höhenlage, in welcher die Entkupplung erfolgt ist, wodurch eine nachfolgende Kupplung erleichtert wird.As soon as the charger 2 is to be removed from the tractor 1 again, the mechanical uncoupling takes place first by means of the hydraulic systems. As a result, the two clutch plates 31 and 51 are uncoupled from one another in that the actuating element 4 is displaced upward by means of the actuating cylinder 41. As a result, the latching hook 46 is pivoted in the counterclockwise direction by the adjusting bolt 48 which interacts with the guide surface 47, as a result of which the two ends of the supporting bolt 53 are released. As a result, the carrier 5 for the clutch plate 51 can be raised by the actuator 4 by a further upward movement of the adjusting element 4, whereby the clutch plate 51 is released from the clutch plate 31. Here, the carrier 5 for the clutch plate 51 slides along the swing arm 6 upwards. Since the free ends of the carrying bolt 53 are subsequently released by the catch hooks 42, the tractor 1 can be completely moved away from the charger 2.
Due to the braking device 55, the carrier 5 remains at the height at which the uncoupling took place, whereby a subsequent clutch is facilitated.
