FIELD: rail transport.
SUBSTANCE: invention relates to axles of axle box axle suspension. Latter is located in axle-box opening with possibility of displacement along bogie axis. Front and rear hydromechanical converters are arranged between the front part of the aperture and the axle box body, as well as between the back part of the axle box opening and the journal box body. Each transducer comprises a rigid body, a plunger and an elastomer body connecting the rigid body with the plunger. Housing and plunger form variable-volume hydraulic chamber. Fluid is fed into the chamber through the inlet.
EFFECT: enlarging functional capabilities of axle box unit.
