FIELD: railway transport; rolling stock.
SUBSTANCE: invention relates to shock absorbing devices with friction vibration dampers of bogies. Overspring beam 2 with support pads for extreme springs of middle row of spring set is installed in device over spring set 3. Overspring beam in cross section has form of equilateral trapezium with large base from below. Friction wedges 4 of vibration damper 1 are pressed to side planes of beam and vertical planes of side frame 6 of bogie by elastic member 5.
EFFECT: improved vibration damping, and reliability, reduced wear and increased service life.
