A two-way assembly consisting of a chassis-frame (11) formed by two branches (17) and (18) articulated pivoting about two end pins (21) and (22) each bearing two inclined guide rollers (14) along a rail (8). The chassis-frame (11) is longitudinally movable relative to the road axle (2) for reversing an automatically guided travel direction by the effect of a reversing actuator (15). The chassis-frame (11) can be lifted after the rollers (14) have disengaged from the guide rail (8) by a lifting mechanism acting on the chassis-frame arms. The axle (12) is automatically guided by a subassembly guided (9) by the chassis-frame (11). The guided subassembly (9) capable of being displaced transversely at the rear about a pivot point located in the proximity of the front rollers. The invention is particularly advantageous to manufacturers of rail-mounted road vehicles. |
