FIELD: railway transport.
SUBSTANCE: invention relates to additional devices designed for reducing vibrations of freight car. Proposed device has flexible member in form of two torsion bars 1 installed in upper part of side frame of freight car bogie 2. Torsion bars are rigidly connected with levers 3 whose opposite ends are coupled by common axle 4. Cylindrical roller 5 is fitted on axle with elastic pressing. Said roller 5 rolls along cylindrical surface of one of two shaped cams fixed on plate 8 at end of overspring beam of car at a distance corresponding to points of static deflection of typical spring suspensions at empty and loaded conditions of car.
EFFECT: reduced dynamic loads in zone of wheel-to-rail contact.
