FIELD: transport.
SUBSTANCE: railroad wheel includes a hub designed to be secured on wheelset axle and a rim with tread area and flange, which is connected to the hub through conical faces capable of independent rotation. One of the conical faces is made on the ring inserted into the wheel, this ring is installed on the hub capable of limited axial movement and is secured against rotation. The ring is spring-loaded against the hub towards the vertex of the conical faces.
EFFECT: reduced wear of conical hub-coupling faces, increased wheel stiffness.
