ELASTIC WHEEL OF RAIL TRANSPORT Russian patent published in 2022 - IPC B60B9/10 

FIELD: rail transport.

SUBSTANCE: invention relates to a structure of a rolling stock of rail transport. An elastic wheel of rail transport contains a bandage with a disc, a hub with a flange, a pressure flange, elastic elements between the bandage disc and hub flanges, and fasteners. Faces of the bandage disc, facing the removable flange and the hub flange, are provided with irregularities in the form of protrusions and recesses between them. The face of the hub flange, facing the bandage disc, is provided with similar irregularities in the form of protrusions, each of which is placed in an adjacent recess of the bandage disc, and recesses between them, in each of which an adjacent protrusion of the bandage disc is placed, with a gap between the specified irregularities. The face of the pressure flange of the hub, facing the bandage disc, is provided with similar irregularities in the form of protrusions, each of which is placed in an adjacent recess of the bandage disc, and recesses between them, in each of which an adjacent protrusion of the bandage disc is placed, with a gap between the specified irregularities, an elastic element is placed in each of the specified gaps. The bandage disc is made of two plates, the face of each plate, facing the adjacent plate, is made with irregularities similar to irregularities of the bandage disc with arrangement adjacent along the axis of the disc with each of recesses of irregularities of the bandage disc facing the adjacent plate of the protrusion and adjacent to each of protrusions of irregularities of the bandage disc facing the adjacent plate of the recess, and plates are interconnected or each of plates is attached to a radial disc located between plates, while each of plates is attached to the bandage.

EFFECT: elasticity is increased, and unsprung weight of a wheel is decreased.
