Anmelder Herbert Weber, Kiteingerstraße 5, 83254 Breitbrunn Lenkung für handgeschobene FahrzeugeApplicant Herbert Weber, Kiteingerstraße 5, 83254 Breitbrunn Steering for hand-pushed vehicles

Beschreibung:Description:

Front oder Hecklenkung für handgeschobene Fahrzeuge mit der Eigenschaft bei geringen Lenkkräften einzulenken und ohne Lenkkraft die spur wieder gerade zu stellen.Front or rear steering for hand-pushed vehicles with the ability to steer with little steering force and to straighten the track again without steering force.

Bisherige Lenkungen fur diesen Einsatz besitzen herkömmliche Gabeltechnik mit einem zentralen Gabelkopf.Previous steering systems for this application have conventional fork technology with a central fork head.

Dabei werden, um die Baügröße gering zu halten ,meist kleine Laufräder verwendet. Bei geschobenen Fahrzeugen wird ein Hinderniss einfacher durch Laufräder mit großem Durchmesser überwunden.In order to keep the size small, small wheels are usually used. When pushing vehicles, obstacles can be overcome more easily using wheels with a large diameter.

Das Problem wird dadurch gelöst, daß beiderseits seitlich von der gelenkten Achse die Auslenkung geschieht.The problem is solved by having the deflection occur on both sides of the steered axle.

Die lenkbare Laufradachse ist die Koppel eines ebenen viergliedrigen Drehgelenkgetriebes. Die Koppel des Getriebes ist kürzer als das Gestell, so daß sich bei betätigen der Kurbeln sich die Koppel um einen veränderlichen Drehpunkt bewegt.The steerable wheel axle is the coupling of a flat four-link swivel gear. The coupling of the gear is shorter than the frame, so that when the cranks are operated, the coupling moves around a variable pivot point.

Die Drehachsen des viergliedrigenDrehgelenkgetriebes sind so aus der Senkrechten geneigt, daß sich in Fahrtrichtun ein Nachlauf ergibt.The axes of rotation of the four-link swivel joint are inclined from the vertical in such a way that a caster occurs in the direction of travel.

Die Laufradachse wird von den beiden Kurbeln des viergliedrigen Drehgelenks in Fahrtrichtung so geschoben ,daß sich sowohl durch den Nachlauf, als auch durch die statische Belastung eine Neutralstellung ,das heißt Geradeausfahrt, einstellt.The wheel axle is pushed in the direction of travel by the two cranks of the four-link swivel joint so that a neutral position, i.e. straight-ahead travel, is achieved by both the caster and the static load.

Die beiden Koppeln sind gleich lang mit gleicher Neutralstellung von Nachlauf und statischer Belastung.The two couplers are the same length with the same neutral position of caster and static load.
