FIELD: railway transport. SUBSTANCE: invention relates to design of devices intended for provision of radial setting of wheelset axle of bogies on curved sections of track. Proposed device contains two wheelsets with axle boxes. Rods are hinge-mounted between thrust brackets of axle boxes. Axes of rods do not intersect with axes of wheelsets. Springs of spring suspension resting on wheelset axle boxes are displaced relative to vertical planes passing through axes of wheelsets through preset value.
