Description
Die Erfindung bezieht sich auf eine Zugmaschine mit einer insbesondere frontseiligen Geräteanbauvorrichtung, die zwei Unterlenker und einen Oberlenker sowie eine quer zur Längsachse der Zugmaschine an dieser schwenkbar gelagerte Hubwelle aufweist, auf der drehfest zwei mit den Unterlenkern über Hubstangen gelenkig verbundene Hubarme sitzen, an welchen mindestens ein Hubzylinder zum Heben und Senken der Unterlenker angreift.The invention relates to a tractor with an especially front-roped implement attachment device, the two lower links and one upper link and one at right angles to the longitudinal axis of the tractor Has pivotably mounted lifting shaft, on the non-rotatable two with the lower links via lifting rods articulated lifting arms sit on which at least one lifting cylinder for raising and lowering the Attacks lower link.
Es ist bei einer mittels Kraftheber heb- und senkbaren Geräteanbauvorrichtung genannter Art bekannt, die Anlenkstelle des Oberlenkers außerhalb der Drehachse der Hubarme des Krafthebers, vorzugsweise unterhalb davon, anzuordnen. Bei einer solchen Anordnung ist ein besonderes Schwenklager für den Oberlenker erforderlich, das an einem kräftigen und gut mit der Zugmaschine verbundenen, gegebenenfalls speziell für das Schwenklager vorgesehenen Rahmenteil befestigt ist. Eine solche Ausführung ist aufwendig und nimmt zusätzlichen Raum in Anspruch.It is known in a type of implement attachment that can be raised and lowered by means of a power lift Articulation point of the upper link outside the axis of rotation of the lifting arms of the power lift, preferably below from ordering. With such an arrangement, a special pivot bearing is required for the top link, that on a strong and well connected to the tractor, possibly especially for the pivot bearing provided frame part is attached. Such a design is complex and takes take up additional space.
Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung der geschilderten Nachteile das Schwenklager so anzuordnen, daß hierfür keine aufwendigen Bauteile erforderlich sind.The invention is based on the object, while avoiding the disadvantages described, the pivot bearing to be arranged so that no complex components are required for this.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der vertikal frei schwenkbare Oberlenker fahrzeugseitig an einer auf der Hubwelle der Geräteanbauvorrichtung drehbar gelagerten Hülse starr befestigt ist. Durch diese Maßnahme wird die Einsparung eines besonderen Schwenklagers und eine gedrungene Bauweise erreicht.This object is achieved according to the invention in that the vertically freely pivotable upper link is on the vehicle side is rigidly attached to a sleeve rotatably mounted on the lifting shaft of the implement mounting device. This measure saves a special pivot bearing and a squat Construction achieved.
In der Zeichnung ist ein in der nachfolgenden
Beschreibung erläutertes Ausführungsbeispiel einer Geräteanbauvorrichtung gemäß der Erfindung vereinfacht
dargestellt.
Die dargestellte Geräteanbauvorrichtung ist insbesondere für die frontseitige Verwendung an einer
Zugmaschine vorgesehen. Dabei sind an einem unteren Rahmenteil 1, das mit der nicht gezeigten Zugmaschine
fest verbunden ist, zwei Lagerböcke 2 und 3 befestigt, i.n denen je ein Unterlenker 4 bzw. 5 schwenkbar gehalten
ist. In den Lagerböcken 2 und 3 sind ebenfalls schwenkbar zwei hydraulische Hubzylinder 6 und 7
gehalten, welche mit ihren oberen Enden an je einem Hubarm 8 bzw. 9 gelenkig angreifen. Die Hubarme 8
und 9 sind einerseits durch je eine Hubstange 10 bzw. 11 gelenkig mit den Unterlenkern 4 bzw. 5 verbunden und
sitzen andererseits drehfest auf einer gemeinsamen Hubwelle 12. Diese Hubwelle 12 ist in Lagerböcken 13
und 14 drehbar gehalten, welche ihrerseits an einem ebenfalls mit der nicht dargestellten Zugmaschine fest
verbundenen oberen Rahmenteil 15 sitzen.In the drawing, an exemplary embodiment of an implement attachment device according to the invention, which is explained in the following description, is shown in a simplified manner.
The device attachment device shown is intended in particular for use on the front of a tractor. Two bearing blocks 2 and 3 are attached to a lower frame part 1, which is firmly connected to the tractor, not shown, in each of which a lower link 4 and 5 is pivotably held. In the bearing blocks 2 and 3, two hydraulic lifting cylinders 6 and 7 are also pivotably held, which at their upper ends act in an articulated manner on a lifting arm 8 and 9, respectively. The lifting arms 8 and 9 are articulated on the one hand by a lifting rod 10 and 11, respectively, with the lower links 4 and 5 and on the other hand are seated in a rotationally fixed manner on a common lifting shaft 12. This lifting shaft 12 is rotatably held in bearing blocks 13 and 14, which in turn are attached to a also sit firmly connected to the tractor, not shown, upper frame part 15.
Wird den hydraulischen Hubzylindern 6 und 7 Druckmittel aus einem hydraulischen System der Zugmaschine zugeführt, so werden die Hubarme 8 und 9 nach oben verschwenkt und heben dabei über die Hubstangen 10 und 11 die Unterlenker 4 und 5 an. Bei Abführung des Druckmittels aus den Hubzylindern werden die Unterlenker 4 und 5 gesenkt.If the hydraulic lifting cylinders 6 and 7 pressure medium from a hydraulic system of the Tractor supplied, the lifting arms 8 and 9 are pivoted upwards and lift over the Lifting rods 10 and 11 the lower links 4 and 5. at Removal of the pressure medium from the lifting cylinders, the lower links 4 and 5 are lowered.
Zwischen den beiden Lagerböcken 13 und 14 sitzt auf der Hubwelle 12 frei drehbar eine Hülse 16, deren seitliche Verschiebbarkeit durch die beiden Lagerböcke begrenzt ist. Rechtwinklig zur Hülse 16 ist mittig ein Oberlenker 17 befestigt. Damit der Oberlenker 17 eine den Belastungen entsprechende starre Verbindung mit der Hülse 16 aufweist, sind zwischen dieser und dem Oberlenker 17 Versteifungsbleche 18 eingeschweißt. Der Oberlenker 17 hat geräteseitig eine Gewindespindel 19, an der ein Gelenkkopf 20 zum Anschluß des Oberlenkers 17 an ein Arbeitsgerät sitzt. Durch Verdrehen des Gelenkkopfes 20 bzw. der Spindel 19 kann die Gesamtlänge des Oberlenkers 17 zur Anpassung an ein Arbeitsgerät verändert werden.Between the two bearing blocks 13 and 14 sits on the lifting shaft 12 freely rotatable a sleeve 16, the lateral displacement is limited by the two bearing blocks. At right angles to the sleeve 16 is a center Upper link 17 attached. So that the upper link 17 has a rigid connection corresponding to the loads the sleeve 16, 17 stiffening plates 18 are welded between this and the upper link. The upper link 17 has on the device side a threaded spindle 19 on which a joint head 20 for connecting the Top link 17 is seated on an implement. By turning the joint head 20 or the spindle 19 the total length of the upper link 17 can be changed to adapt it to an implement.
