Vorrichtung zur Erzielung enger Wendekreise bei
Fahrzeugen mit KnicklenkungDevice for achieving tight turning circles
Articulated vehicles
Die Erfindung betrifft eine Vorrichtung zur Erzielung enger
Wendekreise bei mittels einer Knicklenkvorrichtung miteinander verbundenen Fahrzeugen, insbesondere Gleiskettenfahrzeugen.
The invention relates to a device for achieving closer
Turning circles in vehicles connected to one another by means of an articulated steering device, in particular crawler vehicles.
Fahrzeuge mit Knicklenkung, insbesondere eine Knicklenkvorrichtung
aufweisende Gleiskettenfahrzeuge, weisen meist eine wesentlich bessere Geländegängigkeit auf als mittels der
Gleisketten gelenkte Fahrzeuge ohne Knicklenkung. Der Wendekreisradius
ist bei solchen Fahrzeugen verhältnismäßig groß, er ist abhängig von dem Neigungswinkel, den die Fahrgestell-Vehicles with articulated steering, in particular caterpillar vehicles having an articulated steering device, usually have significantly better off-road mobility than by means of the
Crawler-steered vehicles without articulated steering. The turning radius is relatively large in such vehicles, it depends on the angle of inclination that the chassis

ebenen der beiden mittels einer Knicklenkvorrichtung aneinander gekuppelten Fahrzeuge miteinander bilden.Form levels of the two vehicles coupled to one another by means of an articulated steering device.
Der Erfindung liegt die Aufgabe zugrunde, den Radius des Wendekreises zweier aneinander gekuppelter Fahrzeuge zu verkleinern, um die Manövrierbarkeit zu erhöhen.The invention is based on the object of the radius of the turning circle to reduce the size of two coupled vehicles in order to increase maneuverability.
Hierbei wird von der Überlegung ausgegangen, daß beim Fahren auf ebener, bzw. gleichmäßig geneigter Strecke der Bodendruck der beiden Fahrzeuge über die Länge der Gleisketten im wesentlichen derselbe ist, so daß bei einer Fahrtrichtungsänderung das einzelne Fahrzeug etwa um seine Mitte geschwenkt werden muß. Wird der Abstand der beiden Schwenkmittelpunkte verkürzt, so ergibt sich hieraus eine Verkleinerung des Radius des Wendekreises und damit eine bessere Manövrierbarkeit der beiden aneinander gekuppelten Fahrzeuge.This is based on the assumption that the ground pressure when driving on a level or evenly inclined route of the two vehicles is essentially the same over the length of the tracks, so that when the direction of travel is changed the individual vehicle must be pivoted about its center. If the distance between the two pivot centers is shortened, this results in a reduction in the radius of the turning circle and thus better maneuverability of the two coupled vehicles.
Gemäß der Erfindung wird eine Verlagerung des Schwenkpunktes der beiden Fahrzeuge im Sinne einer Verkürzung des Abstandes der Schwenkpunkte dadurch erreicht, daß zwischen den beiden Fahrzeugen zusätzlich'zu der Knicklenkvorrichtung eine die beiden Fahrzeuge miteinander verbindende Vorrichtung angeordnet ist, die in ihrer Länge einstellbar ist und so die Möglichkeit bietet, den vertikalen Neigungswinkel der beiden Fahrzeuge zu verändern.' . ■-. .According to the invention, a displacement of the pivot point of the two vehicles in the sense of a shortening of the distance between the pivot points is achieved in that, in addition to the articulated steering device, a device connecting the two vehicles is arranged between the two vehicles, the length of which is adjustable and so offers the possibility of changing the vertical angle of inclination of the two vehicles.

Die beiden in Fig. 1 dargestellten, den Fahrzeugzug 10 bildenden, auf ebener Strecke bewegten Fahrzeuge 11 und 12 üben einen über die Länge der Gleisketten gleichmäßig verteilten Bodendruck 13 und 14 aus. Bei der in Fig. 2 dargestellten Kurvenfahrt auf ebener Strecke (06 = 180°) ergibt sich ein Radius r. des Wendekreises mit dem Mittelpunkt 15 von verhältnismäßig großer Länge. Weisen die beiden Fahrzeuge 11 und 12, wie in Fig. 3 dargestellt, in der Vertikalen eine Neigung entsprechend dem Winkel ^C- gegeneinander auf, so verlagern sich die Schwerpunkte der Angriffsflächen der Ketten 16 und 17 des Fahrzeugs 11 und der -Ketten 18 und 19 des Fahrzeugs 12 und damit die Bodendrücke in einer Weise^ wie esin den Diagrammen 20 und dargestellt ist. -Der Radius r- des Wendekreises mit dem Mittelpunkt 15 verkürzt sich damit.in der in Fig. .4 dargestellten Weise, Dieser; Radius kann, wie in Fig. 5 dargestellt, noch verkleinert werden, -so daß er den geringen Wert r, annimmt, wenn bei der Kurvenfahrt die Innenkreisketten 16 und 18 festgestellt und nur die Außenkreisketten 17 und 19 angetrieben werden. Dergl^eg^ekÄeieiK^Mis r- entspricht hierbeiThe two vehicles 11 and 12 shown in FIG. 1, forming the vehicle train 10 and moving on a level route, practice one Ground pressure 13 and 14 evenly distributed over the length of the crawler tracks. When cornering shown in FIG on a level stretch (06 = 180 °) there is a radius r. of the turning circle with the center 15 of relative great length. If the two vehicles 11 and 12, as shown in FIG. 3, have a corresponding inclination in the vertical the angle ^ C- against each other, the centers of gravity shift the contact surfaces of the chains 16 and 17 of the vehicle 11 and the chains 18 and 19 of the vehicle 12 and thus the ground pressures in a manner ^ as shown in diagrams 20 and is shown. -The radius r- of the turning circle with the center point 15 is thus shortened in that shown in Fig. 4 Way, this one; As shown in Fig. 5, the radius can still be reduced so that it assumes the low value r, if when cornering the inner circle chains 16 and 18 established and only the outer circular chains 17 and 19 driven will.
