Abstract: Stabilizing device for compensating by restraining the relative rocking movements between an articulated railroad car body and bogie running at high speed. The device comprises, longitudinally extending across the frame of the bogie a tube having sufficient stiffness for being free of any torsion, adapted to rotate inside bearings disposed at the extremities of the frame. The tube is provided at its extremities, with two parallel crank-arms integrally connected to the tube. The extremity of each of the crank-arms is articulated to a rigid connecting member which is attached on the other hand, by means of a swivel-joint, to a corresponding car body.
