<p>The assembly has a towing vehicle (1) including a frame (10), a trailer (2) and an axial guidance system. A connection device (6) is assembled symmetrically on the frame of the towing vehicle. Another connection device (7) is assembled symmetrically on a frame (20) of the trailer. A coupling device (8) e.g. hydraulic coupling device, is allowed to act on the former connection device and/or the latter connection device to ensure identity of relative longitudinal displacements of the latter connection device and/or of moving parts i.e. rods.</p> |
