RAILROAD WHEEL BY V.V.BODROV Russian patent published in 2016 - IPC B60B17/00 

FIELD: transport.

SUBSTANCE: invention relates to railway transport and can be used in passenger and freight speed cars bogies wheel pairs. Railroad wheel comprises hub and rim with tread area and flange, connected to hub with possibility of independent rotation, viscoelastic ring installed between them without gaps, bushing made from metal with low dry friction sliding coefficient by steel between ring and rim adjacent surfaces and highly heat-conducting soft antifriction material powder on sliding surface. Wheel rim (2) is made with ring groove on flange side and with radial thrust (3) on opposite side on inner radius. Height of radial thrust (3) is at least twice exceeds viscoelastic ring (4) thickness. Wheel rim (2), viscoelastic ring (4) and wheel center (1) are connected in assembly unit by stop ring. Assembled unit radial section is inscribed in wide gage railway rolling stock standard-rolled wheel radial cross-section.

EFFECT: enabling lower costs, reduced wheel rolling resistance and safety of operation.
