TWO-WAY GUIDING ASSEMBLY ALONG A RAIL FOR A ROAD AXLE LATERAL OFFSET

摘要

The invention concerns 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 mobile relative to the road axle (2) for reversing the automatically guided travel direction by the effect of a reversing actuator (15). The chassis-frame (11) can be lifted after the rollers (14) have been 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) said guided subassembly (9) capable of being displaced transversely at the rear about a pivot point located in the proximity of the front rollers. Said invention is of particular interest to manufacturers of rail-mounted road vehicles.
