Abstract

The circular steering arrangement has track rods (6) which are variable in length. The changes in length can be carried out hydraulically or mechanically. The track rods in the retracted state can execute all known types of conventional steering. In the extended state of the track rods the wheels (3) roll around a circular track, thereby enabling turning on the spot.

Description

Die Erifndung bezieht sich auf einen möglichst kleinen Wendekreis von Räderfahrzeugen, durch Veränderung der Länge der Spurstangen.The Erifndung refers to the smallest possible turning circle of wheeled vehicles, through change the length the tie rods.

Der Stand der Technik bietet hier ein Gegenlaufen der Radseiten an. Dieses bringt einen sehr hohen Reifenverschleiß und Kraftaufwand mit sich. Angewandt hauptsächlich bei Kompaktladern.Of the The state of the art here offers counteracting of the wheel sides. This brings a very high tire wear and expenditure of energy. Applied mainly on skid steers.

Einige Rasenmäher treiben nur eine Achse gegenläufig an und lassen die andere Achse abrollen, hier verdoppelt sich der Wendekreis etwas über den Fahrzeugachsabstand (Radstand). Durch den verhältnismäßig großen Wendekreis, ist diese Lenkung nicht mit der Erfindung zu vergleichen. Sie ist Achslastabhängig und nicht sehr Geländetauglich.Some mowing machine drive only one axis in opposite directions and let roll the other axis, here doubles the Tropic something about the Vehicle axle distance (wheelbase). Due to the relatively large turning circle, this steering is not to be compared with the invention. It is axle load dependent and not very off-road suitable.

Die Allradlenkung ist im Gelände einsetzbar und die Räder rollen Boden schonend ab, aber es ist auch hier kein Wendekreis über den Mittelpunkt der Fahrzeugdiagonale. Der Wendekreis ist etwas größer als bei der vorher genanten.The All-wheel steering is off-road can be used and the wheels roll off soil gently, but it is also here not a turning circle over the Center of the vehicle diagonal. The turning circle is slightly larger than at the aforementioned.

Die Erfindung bezieht sich auf eine Leicht abrollende, für Allradantrieb geeignete Fahrzeugdrehung um den Mittelpunkt der Fahrzeugdiagonale zwischen den Rädern. Der Wendekreis Außendurchmesser entspricht der Fahrzeugdiagonale.The The invention relates to a lightweight rolling, for all-wheel drive suitable vehicle rotation about the center of the vehicle diagonal between the wheels. The turning circle outer diameter corresponds to the vehicle diagonal.

Während normaler Straßenfahrt wird das Fahrzeug Standardmäßig gelenkt. Es kann auch dem Stand der Technik entsprechend mit Allradlenkung und Krebs oder Hundegang gelenkt werden. Dies geschieht wie bekannt über Schubstange, Schubstangenhebel, Spurstangenhebel und Spurstange.While normal road travel the vehicle is steered by default. It can also according to the prior art with all-wheel steering and can be directed to cancer or crab. This is done as known about push rod, push rod lever, Tie rod lever and tie rod.

1 zeigt den Zustand der Spurstangen für Standard Lenkungsarten. 1 shows the condition of the standard steering tie rods.

Bei den Standardlenkungsarten sind die Spurstangen 6 eingefahren Situation 11.In the standard steering types are the tie rods 6 retracted situation 11 ,

2 ist die Darstellung der Kreislenkung. 2 is the representation of the circular steering.

Um eine Drehung auf der Stelle zu ermöglichen sind die Spurstangen Teleskopisch ausgebildet. Soll nun auf der Stelle gewendet werden, Teleskopieren die Spurstangen in eine vorgegebene Endlage aus, Situation 10, so das die Räder 3 beim abrollen einen Kreis 9 ergeben.To enable rotation on the spot, the tie rods are telescopically formed. Should now be turned on the spot, Telescoping the tie rods in a predetermined end position, situation 10 That's how the wheels are 3 when rolling a circle 9 result.

Das Austeleskopiren kann mechanisch über eine Spindel oder einfacher über einen doppelt wirkenden Hydraulikzylinder, siehe Darstellung, erfolgen. Die Endlage wird einmal durch das Austeleskopieren vorgegeben, den maximalen hub der Hydraulikzylinder. Zum Zentrieren um den Fahrzeugmittelpunkt befinden sich an der Achse und den Achsschenkeln Anschläge, oder dieses wird durch die Schubstangen 13 über den Schubstangenhebel 12 erreicht.The Austeleskopiren can be done mechanically via a spindle or more easily via a double-acting hydraulic cylinder, see illustration. The final position is once given by the Austeleskopieren, the maximum stroke of the hydraulic cylinder. For centering around the vehicle center are on the axis and the stub axle stops, or this is by the push rods 13 over the push rod lever 12 reached.

Um einen einfachen Allradantrieb zu ermöglichen empfiehlt es sich Radnabenmotore 4 zu benutzen. Diese lassen sich am einfachsten gegenläufig antreiben.To enable a simple four-wheel drive, it is recommended wheel hub motors 4 to use. These are the easiest to drive in opposite directions.

Der Wirtschaftliche Nutzen besteht in dem einfachen und robusten Aufbau der Konstruktion. Dem Minimum an Platzbedarf für eine Fahrzeugdrehung. Hier durch kann bei Dumpern und Spezialmaschinen auf gefährliches Rückwärtsfahren und Rangieren verzichtet werden. Bei Hebezeugen die viel Wegstrecken zurücklegen müssen, kann so oft auf einen Kostspieligen Drehkrans verzichtet werden. Das Haupteinsatzgebiet könnte bei Teleskopladern liegen. Diese könnten so ihre Wendigkeit und somit auch ihre Arbeitsgeschwindigkeit erheblich steigern. Die Fahrzeuglänge bestimmt hier die Größe des Hüllkreises.Of the Economic benefits consist in the simple and robust construction the construction. The minimum amount of space required for a vehicle turn. Here can be dangerous on dumpers and special machines Drive backwards and maneuvering are dispensed with. When lifting the long distances return have to, can be dispensed so often on a costly rotary crane. The Main application area could lie with telescopic loaders. These could be so maneuverable and thus significantly increase their working speed. The vehicle length determines here the size of the outer circle.

Die Schutzrechtansprüche beziehen sich auf, die durch das Austeleskopieren der Spurstangen, und dadurch in einem Kreis abrollenden Räder um den Fahrzeugmittelpunkt.The Patent claims refer to the removal of the tie rods by telescoping, and thereby in a circle rolling wheels around the vehicle center.

Durch die vorgegebenen Anschläge zwischen den Achsschenkeln und dem Achsgehäuse oder der Endlage der Schubstange 13, siehe 2.By the given stops between the stub axles and the axle housing or the end position of the push rod 13 , please refer 2 ,
