Description

Schlepperradachse Die Erfindung bezieht sich auf eine Schlepperradachse mit mittels einer Parallelogrammführung in Querrichtung veränderbarem Radstand. Bisher wurde die Verschwenkung der Parallelogrammführung nur dazu benutzt, die Spurbreite zu ändern.Tractor wheel axle The invention relates to a tractor wheel axle with a wheelbase that can be changed in the transverse direction by means of a parallelogram guide. So far, the pivoting of the parallelogram guide has only been used to adjust the track width to change.

Der Erfindung liegt die Aufgabe zugrunde, auf einfache Weise sowohl eine Änderung der Spurbreite als auch der Höhenlage des Schlepperrahmens gegenüber den Schlepperrädern zu ermöglichen.The invention is based on the object in a simple manner both a change in the track width as well as the height of the tractor frame to enable the tractor wheels.

Dies erfolgt erfindungsgemäß dadurch, daß die Parallelogrammführung als Ganzes um eine im wesentlichen waagrechte Achse gegenüber dem Schlepprahmen schwenkbar ist, so daß sowohl die Spurbreite als auch der Radstand beliebig eingestellt werden kann.According to the invention, this takes place in that the parallelogram guide as a whole around an essentially horizontal axis with respect to the towing frame is pivotable, so that both the track width and the wheelbase can be set as desired can be.

Zweckmäßig verläuft dabei die waagerechte Achse quer zur Fahrtrichtung, und die Parallelogrammführung ist als Ganzes um etwa 90° um die waagrechte Achse verschwenkbar.The horizontal axis expediently runs transversely to the direction of travel, and the parallelogram as a whole is about 90 ° around the horizontal axis pivotable.

In den Zeichnungen zeigt Fig. 1 die Draufsicht auf den rückwärtigen Teil eines Schleppers und Fig.2 eine Seitenansicht eines Hinterrades des Schleppers, in Richtung II-II der Fig. 1 gesehen. Gemäß Fig. 1 ist im rückwärtigen Teil des Schlepperrahmens 39 auf jeder Seite eine Welle 40 gelagert, um die Tragarme 40A drehbar sind. Der Fahrer kann den Wellen 40 und den Tragarenen 40 A eine innerhalb bestimmter Grenzen beliebige Winkellage geben, z. B. mittels Zahnstangen, die in auf den Wellen 40 befestigte Zahnräder eingreifen.In the drawings, Fig. 1 shows the plan view of the rear Part of a tractor and FIG. 2 a side view of a rear wheel of the tractor, seen in the direction II-II of FIG. According to Fig. 1 is in the rear part of the Tractor frame 39 on each side a shaft 40 mounted to the support arms 40A are rotatable. The driver can the shafts 40 and the carrying arenas 40 A within give certain limits any angular position, z. B. by means of racks in gear wheels mounted on shafts 40 engage.

An jedem Tragarm 40A sind zwei parallele Schwenkachsen gelagert. Auf der rechten Radseite sind dazu Achsen 41 und 42 vorgesehen, um die Arme 43 und 44 schwenkbar sind. Diese sind andererseits mit den Achsen 41 und 42 parallelen Achsen 47 und 48 an einem Achshalter 45, der den Achsstummel für das Hinterrad 46 des Schleppers trägt, angelenkt (s. auch Fig. 2). Der Arm 43 ist, zwischen den Achsen 41 und 47 gemessen, gleich lang wie der Arm 44 zwischen den Achsen 42 und 48, und der Abstand zwischen den Achsen 41 und 42 ist gleich dem Abstand zwischen den Achsen 47 und 48. Die Arme 43 und 44 bilden also die gegenüberliegenden Seiten eines Parallelogramms, die stets parallel bleiben, wenn das Rad 46 gegenüber dem Rahmen seitlich verschwenkt wird. Bei einem derartigen Verschwenken des Rades bleibt die Radebene 46 stets der Längsmittelebene des Schleppers parallel. Die Achsen 42 und 47 sind durch eine ihren gegenseitigen Abstand festlegende Vorrichtung 49 miteinander verbunden. Diese Vorrichtung 49 besteht aus einem gelenkig an der Achse 47 befestigten Zylinder und aus einem in diesem Zylinder bewegbaren, gelenkig an die Achse 42 angeschlossenen Kolben. Eine ausdehnbare Hülle 50 umgibt den Kolbenteil der Vorrichtung, soweit dieser aus dem Zylinder hinausragt. Der Abstand von Rad 46 bis zur Längsmittelebene des Schleppers kann dadurch eingestellt werden, daß eine bestimmte Ölmenge einer der beiden Kammern des Zylinders zugeführt wird. Eine gleiche Anordnung ist beim linken Hinterrad 51 vorgesehen, so daß dieses Rad in der dargestellten Lage des Tragarmes 40A in Richtung des Pfeiles 52 bewegt werden kann. Der Antrieb der Räder 46 und 51 kann mittels in den Naben eingebauter, durch Drucköl getriebener Motoren geschehen. Biegsame Ölzuführungsleitungen und Ölabfuhrleitungen 53 bzw. 54 sind mit Ölleitungen im Gestell 39 verbunden.Two parallel pivot axes are mounted on each support arm 40A. For this purpose, axles 41 and 42 are provided on the right-hand side of the wheel, around which arms 43 and 44 can be pivoted. On the other hand, with axles 47 and 48 parallel to axles 41 and 42, these are articulated to an axle holder 45 which carries the axle stub for the rear wheel 46 of the tractor (see also FIG. 2). The arm 43 is, measured between the axes 41 and 47, the same length as the arm 44 between the axes 42 and 48, and the distance between the axes 41 and 42 is the same as the distance between the axes 47 and 48. The arms 43 and 44 thus form the opposite sides of a parallelogram, which always remain parallel when the wheel 46 is pivoted laterally relative to the frame. When the wheel is pivoted in this way, the wheel plane 46 always remains parallel to the longitudinal center plane of the tractor. The axes 42 and 47 are connected to one another by a device 49 which defines their mutual spacing. This device 49 consists of a cylinder that is articulated to the axis 47 and of a piston that can be moved in this cylinder and is articulated to the axis 42. An expandable sheath 50 surrounds the piston part of the device to the extent that it protrudes from the cylinder. The distance from wheel 46 to the longitudinal center plane of the tractor can be adjusted by supplying a certain amount of oil to one of the two chambers of the cylinder. The same arrangement is provided for the left rear wheel 51, so that this wheel can be moved in the direction of arrow 52 in the illustrated position of the support arm 40A. The wheels 46 and 51 can be driven by means of motors built into the hubs and driven by pressurized oil. Flexible oil supply lines and oil discharge lines 53 and 54 are connected to oil lines in the frame 39 .
