Abstract (en)

The vehicle (2) is articulated on its bogie (4) with respect to the chassis. It has a bogie support (16) and two connecting rods (8,10) that are articulated to an adjacent vehicle (2') and two levers (12,14) which are also articulated to the bogie support. The levers are free to pivot with respect to the median axes without acting on the support bogie whilst the connecting rods are subjected to longitudinal movements acting in the same directions. When the connecting rods are subjected to longitudinal movements in the opposite direction, the levers are driven in rotation about their pivot axis which is arranged at their adjacent ends. This causes the bogie support to rotate about its axis (18).

Abstract (fr)

Ce véhicule (2) est pourvu de moyens d'articulation du bogie (4) par rapport au châssis, qui comprennent un organe de support (16) du bogie (4), deux bielles (8, 10) destinées à être articulées à un véhicule ferroviaire voisin (2') et deux leviers (12, 14) articulés aux bielles (8, 10), et adjacents l'un de l'autre, les leviers étant en outre articulés à l'organe de support (16), les leviers (12, 14) étant libres de pivoter par rapport à des axes médians (20, 22), sensiblement sans action sur l'organe de support (16), lorsque les bielles (8, 10) sont soumises à des actions longitudinales dirigées selon un même sens, et lorsque les bielles (8, 10) sont soumises à des actions longitudinales dirigées selon des sens opposés, lesdits leviers sont alors entraînés en rotation autour d'un axe de pivotement des leviers, voisin de leurs extrémités adjacentes, de manière à provoquer la rotation de l'organe de support (16) autour de son axe (18). <IMAGE>
