FIELD: rail transport.
SUBSTANCE: invention relates to railway transport, particularly, to railway car bogies. Cart comprises frame, mounted axles and spring set. Frame comprises side members connected by bolster beam. Wheel pairs are divided into two semi-axles. On both sides of wheel there are axle box units mating wheel with sidewall. Wheel pair semi-axes are articulated via spring. Wheels are installed on additional axle by means of metal-polymer bearings with corrugated surface. Additional axes are rigidly connected with boxes. Non-rotating axes of wheel pairs are connected with axles via damping elements made of corrugated plates. Additional axle can move relative to sidewall in transverse direction of bogie.
EFFECT: reduced wear of car running gear and track assembly parts and parts.
