FIELD: railway transport.
SUBSTANCE: proposed axle-box has housing 1, brackets 2,3 with axle-box springs 15, longitudinal ribs connecting brackets with axle-box housing, wheelset axle, link, and wheelset axle radial setting mechanism. Axle-box is connected with lower or middle part of lever 11 by eye plate 7 or flange found on longitudinal ribs of brackets and it is connected by middle or lower part of lever with frame of bogie by link 13 arranged, respectively, higher or lower or at lever of wheelset axle, and is hinge-connected by upper part of lever with body 20 of rail vehicle of frame of bogie 19 by wheelset axle redial setting mechanism. Minimum horizontal distances between axis of body and axis of eye plates or support plane of flange and vertical distances between axis of eye plates or axis of body, link and upper hinge joint of lever are chosen from mechanical equation.
EFFECT: reduced longitudinal rigidity of axle-box unit and wheelset, provision of radial setting of wheelset axle, reduced resistance to movement, noise in curved sections of track, wear of wheel tires, rail and other units.
