Forward steering for trailing vehicles

Die Erfindung betrifft eine Lenkung für Anhänger-Fahrzeuge mit einem starren Zugelement, insbesondere Zuggabel, welches mit seinem einen Ende hinten an der Zugmaschine und mit seinem anderen Ende, insbesondere mittels Drehkranz an der Anhänger-Vorderachse angelenkt ist, wobei die Anhängervorderachse (3) eine eigene von der Drehlagerung (23, 24) der Zuggabel (29, 30) unabhängige Drehlagerung (26) besitzt und für eine Lenkung der Anhänger-Vorderachse auf einem grösseren Kurvenfahrradius als demjenigen der Zugmaschinenhinterseite zusätzliche Lenkübertragungselemente (27-33) vorgesehen sind, derart, dass bei Kurvenfahrten durch die Winkelbewegung des Anhängers (25) zur Zugmaschine (16) der Anhänger (25) durch die Zuggabel (29, 30) nur gezogen, aber ausschliesslich durch die Lenkübertragungselemente (27-33) gelenkt wird. 1. Forward steering gear for the unitary steerable front axle (3) of trailer vehicles (6) equipped with front and rear axles and having a rigid draw bar (5) which is pivoted at one of its ends on a pivoting coupling (2) at the rear of the towing machine (16) and is pivoted at its other end by means of a rotatable bearing (23, 24) at the front of the trailer, in which the trailer front axle (3) has its own front axle rotatable bearing (26) independent of the draw bar rotatable bearing (23, 24) and, for steering the trailer front axle on a larger radius (10) of curved movement than that of the towing machine rear axle, the front axle rotatable bearing is adjustable by means of additional steering transfer elements (27-33) in dependence on the angular movement between the rear end of the towing machine and the front end of the trailer, the trailer being pulled only by the draw bar (5), but being pivoted by the steering transfer elements (27-33), characterized in that, as the steering transfer element, a tiller strut arrangement (29, 30) is provided which extends neither laterally swingable nor laterally movable with respect to the towing machine from the rear end of the towing machine to the trailer (17), and which is connected by means of a pivot point (31) provided on its rear end with the front axle rotatable bearing (26) and by means of a sliding guide (27, 28) with the trailer front axle (3).
