FIELD: construction.
SUBSTANCE: device comprises horizontal frame of longitudinal and transverse beams, adjustable means of limitation of longitudinal and transverse movement of the bogie side frames and means of suppressing wobble oscillations. Device also contains clamping brake with fixed to transverse beams horizontal frame at each bogie wheels to turn in horizontal plane of two mirror identical holders with brake shoes and nuts of screw pair, screw of which in zone of screw pairs has right and left threads, equipped with adjustable spring and articulated lever system and links with other screws of clamping brakes, with lever and brake system with braking cylinder of car and/or truck.
EFFECT: possibility of transporting car with speed equal to structural speed of bogies with zero transition probability in uncontrolled mode of self-oscillations wobble, and effective braking with the speed without increasing the braking distance and force action on wheel rolling surface.
