Description
Die Erfindung betrifft ein selbstfahrendes Gerät gemäß des Oberbegriffes des Patentanspruches 1.The invention relates to a self-propelled device according to the preamble of
Ein derartiges selbstfahrendes Gerät ist aus der
Das Problem bei derartigen Geräten besteht darin, vor allem bei der Fahrt am Seitenhang, eine gute Richtungsstabilität zu erreichen. Insbesondere kann es problematisch sein, die Hinterräder überhaupt in Geradeausposition zu bringen.The problem with such devices is, especially when driving on the side slope, to achieve good directional stability. In particular, it can be problematic to bring the rear wheels at all in the straight ahead position.
Der Erfindung liegt daher die Aufgabe zugrunde, u. a. auch am Seitenhang eine gute Richtungsstabilität in einfacher Weise und eine stabile Geradeausfahrt ohne großen baulichen Aufwand zu erreichen.The invention is therefore based on the object u. a. to achieve good directional stability in a simple manner and a stable straight ahead on the side slope without major construction effort.

Die oben genannte Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Infolge dieser Maßnahmen wird das Fahrzeug bei reiner Geradeausfahrt stabilisiert. Insbesondere ist es auch möglich, die nachlaufenden Räder automatisch in eine Geradeausfahrtposition zu bringen. Darüber hinaus vollzieht das Fahrzeug die Richtungsänderung von Kurvenfahrt in Geradeausfahrt wesentlich schneller als bisher bekannt. Es wird weiterhin bei der Geradeausfahrt am Seitenhang eine Richtungsänderung durch Rutschen des weniger belasteten Antriebsrades vermieden. Die erfindungsgemäße Steuerung lässt sich auch bei der bekannten Lenkhebelsteuerung anwenden.The above object is achieved by the features of
Aufgrund der erfindungsgemäßen Lösung werden die nachlaufenden Räder bei der Vorwärts- und Geradeausfahrt automatisch in die Geradeausfahrtposition gebracht. Wenn die Kurvenfahrt durch Relativbewegung der beiden Lenkhebel, die die Antriebsräder ansteuern, eingeleitet wird, wird diese Zwangsführung aufgehoben und die nachlaufenden Räder können sich führungslos bewegen.Due to the solution according to the invention, the trailing wheels are automatically brought in the straight ahead driving position when driving forward and straight ahead. If the cornering is initiated by relative movement of the two steering levers that drive the drive wheels, this forced guidance is released and the trailing wheels can move without guidance.
Um die nachlaufenden Räder in einfacher Weise bei Geradeausfahrt gerade zu stellen, ist vorgesehen, dass an den Schwenkbolzen jeweils Hebel angeordnet sind, an welchen die Stelleinrichtung beabstandet zur Schwenkachse angreift, und dass die Stelleinrichtung zwischen den beiden Hebeln angeordnet ist.To make the trailing wheels in a straightforward straight ahead driving, it is provided that each lever are arranged on the pivot pin, on which the adjusting device engages spaced from the pivot axis, and that the adjusting device is arranged between the two levers.
In einfacher Weise lässt sich die Stelleinrichtung als Hydraulikzylinder ausbilden. Hierdurch ist die Stelleinrichtung einfach anzusteuern.In a simple way, the adjusting device can be formed as a hydraulic cylinder. As a result, the actuator is easy to control.
Weitere Einzelheiten der Erfindung sind der Beispielsbeschreibung und den Zeichnungen zu entnehmen. Hierbei zeigenFurther details of the invention can be taken from the example description and the drawings. Show here

Durch entsprechendes Auslenken der Handlenkhebel
Durch Zurückziehen einer der beiden Hebel kann der linke oder rechte Ölmotor in der Geschwindigkeit reduziert werden, oder sogar in der Drehrichtung umgekehrt werden, so dass ein schnelles Wenden und Drehen auf der Stelle möglich wird.By retracting one of the two levers, the left or right oil motor can be reduced in speed, or even reversed in the direction of rotation, allowing fast turning and turning on the spot.
