ELASTIC WHEEL (VERSIONS) Russian patent published in 2018 - IPC B60B17/00 

FIELD: railway transport.

SUBSTANCE: inventions relate to the rail transport. In the elastic wheel with the shroud disk, of hub flanges and elastic elements between them, on one edge facing the hub flange or two edges of the shroud disk irregularities in the form of protrusions and recesses between them are made. Adjacent to the shroud disk irregularities, the hub flange edge is provided with similar protrusions, each of which is placed in the shroud disk adjacent recess, and recesses between them, in each of which the shroud disk protrusion is placed. Between the irregularities elastic elements in the form of a rubber or rubber-cord gasket or an elastic steel or synthetic washer with elastic cantilevered cutouts are arranged. In the reinforced version, one or more shroud disks and one or more hub flanges with similar irregularities and elastic elements between them are added. On the external flange outer side, a fixing disc with a rim is screwed in onto the wheel hub, clamping heads or circumferential screws external end faces, and with cantilevered cutouts interacting by their irregularities with irregularities of the external part for fixing against unscrewing.

EFFECT: technical result is an increase in the wheel reliability and service life, as well as a reduction in the noise level.
