<p>The device of this invention is a device for linking two movable bodies, one of which is a trailer (2) coupled to the other which is a tractor (1), in order to optimise the trajectory of the said trailer with respect to the said tractor. The device comprises a drawbar (3) articulated at its two ends (6,7), connected on one side to the rear of the tractor (1) and on the other side to the front of the trailer (2), the latter resting and rolling on at least three wheels (4,5), two (41 and 42) of which, at most, are in fixed planes parallel to the axis (X,X') of the trailer (2) and situated laterally each on either side of this axis, and at least one (5) is mounted so as to be idle and directionally free. In the present invention at least the said articulation (6) of the end of the drawbar (3) on the tractor (1) is mounted on any means (8,12) allowing the angle alpha which the drawbar (3) makes with the axis (Y,Y') of the tractor (1) to be modified at will. <IMAGE></p> |
