摘要

P The coupling system according to the invention comprises a connecting arm (5) disposed between the front (8) of the trailer and the drawbar (7) of the tractor, which is fixed and articulated on the lifting arm (9). BR/ The link arm (5) comprises articulation means around a roll axis (13) and hinge means around two axes of shoelaces (11, 12), permutable, arranged for one at the lower central part of the front face (8) of the trailer, and for the other at the drawbar (7). BR/ The device comprises means for locking one or the other axis of laces (11, 12) to perform an alternative selection of said axes. These means may be in the form of a latch (20) sliding associated with lever type operating means (23) or hydraulic cylinder. BR/ This coupling system improves the traction or the reverse, thanks to the choice of positioning the yaw axis. / P
