Die Erfindung betrifft eine Anordnung des Bedienungsgestänges an mittels Holmen geführten, vorzugsweise einachsigen, landwirtschaftlichen Kleinschleppern mit um eine aufrecht stehende Achse schwenkbarem Holmentragkopf. Während sich bei bekannten Ausführungen derartiger Kleinschlepper die Getriebehebel außerhalb des Holmentragkopfes befinden, ist erfindungsgemäß der Gang wechsel-Getriebeschalthebel im Innern des Holmentragkopfes gelagert. Diese Maßnahme hat gegenüber den bisherigen Anordnungen den Vorteil, daß das Schaltgestänge vor Beschädigungen und Verstaubung geschützt liegt. Außerdem ist die Übertragung der Schaltvorgänge infolge der Anordnung der Übertragungsmittel in der Drehachse des Kopfes sehr einfach.The invention relates to an arrangement of the operating linkage on guided by means of spars, preferably single-axle, small agricultural tractors with an upright standing Axis swiveling spar support head. While in known designs of such small tractors the gear levers are located outside of the spar support head, is according to the invention Gear change gear shift lever stored inside the spar support head. This measure has compared to the previous arrangements the advantage that the shift linkage from damage and Protected from dust. In addition, the transmission of the switching operations is due to the arrangement the transmission means in the axis of rotation of the head is very simple.
In den Zeichnungen sind zwei Ausführungsbeispiele für eine Schaltanordnung nach der Erfindung dargestellt.In the drawings are two exemplary embodiments of a switching arrangement according to the invention shown.
Abb. ι zeigt eine Anordnung im Längsschnitt in verriegelter Stellung des Holmentragkopfes,Fig. Ι shows an arrangement in longitudinal section in locked position of the spar support head,
Abb. 2 einen Längsschnitt durch eine andere Anordnung in schaubiidlicher Darstellung bei entriegelter Stellung des Holmentragkopfes.Fig. 2 is a longitudinal section through another arrangement in a schematic representation with the unlocked position of the spar support head.
Die Anordnung nach der Abb. ι besteht in der Hauptsache aus dem Holmentragkopf ι mit den beiden Holmen 2, von denen nur einer sichtbar ist, sowie dem an der Zugmaschine sitzenden Kopfträger 3 als Getriebegehäuse. Die Holme sind nach Lösen des Knebels 4 um die Achse A in lotrechter Richtung schwenkbar. Der Holmenfaragkopf ist nach Anheben des druckfederbelasteten Riegels 5 mittelsThe arrangement according to Fig. Ι consists mainly of the spar support head ι with the two spars 2, of which only one is visible, and the head support 3 sitting on the tractor as a gear housing. After loosening the toggle 4, the spars can be pivoted about the axis A in the vertical direction. The spar faragkopf is after lifting the compression spring-loaded bolt 5 by means of
des Doppelarmhebels 6 und des in Richtung C verstellbaren Zugrohres 7 um die lotrechte Achse B schwenkbar. Das Zugrohor 7 ist auf dem von Hand zu betätigenden Schaltglied 8, welches in Richtung des Pfeiles D verdrehbar und in Richtung des Pfeiles C verschiebbar ist, gelagert. Das Schaltglied 8 umfaßt mit seinem hülsenartigen Ende den Kugelkopf ga des Getriebeschalthebels 9, welcher mittels seiner kugelkopfartigen Verstärkung gb in einem Quersteg des Holmenkopfes, und zwar in dessen lotrechter Drehachse schwenkbar gelagert ist. Mit seinem anderen kugelförmig gestalteten Ende gc greift er in die Schaltgabel 10 ein, die in bekannter Weise auf das Gangwechselgetriebe einwirkt. Bowdenzüge 11 führen von den Handgriffen der Holme durch die Öffnung ifl in den Holmentragkopf und in den Kopfträger hinein und sind an ihrem Ende, z. B. an Kupplungen, Differentialsperren, Bremsen usw., angeschlossen, ao Kerbverzahnungen zwischen den Holmen 2 und dem Kopfträger 3 vergrößern den Reibungsschluß zwischen diesen Teilen und entlasten den Knebel 4. Die Anordnung nach der Abb. 2 besteht in der Hauptsache aus dem Holmentragkopf 1 mit zwei nicht dargestellten Holmen sowie dem Kopfträger 3 als Getriebegehäuse. Der Holmentragkopf ist nach dem Hochheben der Riegel 12 entgegen Federbelastung mittels des in Richtung des Pfeiles E schwenkbaren und in Richtung des Pfeiles F verschiebbaren Getriebeschalthebels 13 um die lotrechte Mittelachse B des 'Tragkopfes schwenkbar. Am Getriebeschalthebel befindet sich der Arm i3B, der mittels Kugelkopfes an den Arm I4? des Schaltgliedes 14 angeschlossen ist, welches in Richtung des Pfeiles G schwenkbar und in Richtung des Pfeiles H verschiebbar ist. Am Getriebeschalthebel sind ferner Schaltsterne 15 angeordnet, welche mit den Schaltgabeln 16 des Gangwechselgetriebes in Eingriff bringbar sind.of the double arm lever 6 and of the draw tube 7 adjustable in the direction C can be pivoted about the vertical axis B. The pull tube 7 is mounted on the manually operated switching element 8, which can be rotated in the direction of the arrow D and displaced in the direction of the arrow C. The switching member 8 comprises with its sleeve-like end the ball head g a of the gear shift lever 9, which is pivotably mounted by means of its ball-head-like reinforcement g b in a crosspiece of the spar head, namely in its vertical axis of rotation. With its other spherical end g c it engages in the shift fork 10 , which acts in a known manner on the gear change transmission. Bowden cables 11 lead from the handles of the spars through the opening i fl into the spar support head and into the head support and are at their end, for. B. to clutches, differential locks, brakes, etc., ao serrations between the spars 2 and the head support 3 increase the frictional engagement between these parts and relieve the toggle 4. The arrangement according to Fig. 2 consists mainly of the spar support head 1 with two spars, not shown, as well as the head support 3 as a gear housing. After lifting the bolt 12, the spar support head can be pivoted about the vertical center axis B of the 'support head by means of the gear shift lever 13 which is pivotable in the direction of arrow E and displaceable in the direction of arrow F against spring loading. Arm i3 B is located on the gear shift lever, which is attached to arm I4 ? of the switching element 14 is connected, which is pivotable in the direction of the arrow G and displaceable in the direction of the arrow H. On the gear shift lever there are also shift stars 15 which can be brought into engagement with the shift forks 16 of the gear change transmission.
Wird der Getriebeschalthebel 13 nach unten geschoben, dann greifen die Riegel in Löcher 3a ein, der 'dargestellte Schaltstern 15 in die dargestellte Schaltgabel, während die Nase 17 am Getriebeschalthebel durch eine der Nuten I6 der Gleitbahn ic Jiindurchgleitet. Die Nutung ib entspricht der Einstellmöglichkeit des Holmentragkopfes und der Teilung der Löcher 3a, so. daß das Gangwechselgetriebe nur geschaltet werden kann, wenn die Riegel ein Schwenken des Holmentragkopfes gegenüber dem Kopfträger verhindern, mithin die Riegel im Kopfträger im Eingriff sind. Durch Verschieben des Schaltgliedes in Richtung des Pfeiles H wird die Schaltgabel in Richtung des Pfeiles K verstellt.Is the transmission shift lever is pushed 13 downward, then the bolts engage into holes 3 a, a, of the 'star wheel 15 shown in the illustrated shift fork, while the nose 17 on the gear shift lever by one of the grooves I 6 of the slide i c Jiindurchgleitet. The groove i b corresponds to the adjustment of the spar support head and the division of the holes 3 a , see above. that the gear change transmission can only be switched when the bolts prevent pivoting of the spar support head with respect to the head carrier, and consequently the bolts in the head carrier are in engagement. By moving the switching element in the direction of the arrow H , the shift fork is adjusted in the direction of the arrow K.
