<p>Disclosed are a train wheel and a train. The train wheel comprises a hub (1) and a wheel rim (2), the hub being connected to the wheel rim via webs (3), wherein the thickness of the wheel rim is 6%-7% of the diameter of a rolling circle of the wheel, the thickness of the hub is 5%-6% of the diameter of the rolling circle of the wheel; the thickness of the webs near the wheel rim is 2%-3% of the diameter of the rolling circle of the wheel, and the thickness of the webs near the hub is 4%-5% of the diameter of the rolling circle of the wheel. By optimising the size of each component of the wheel, the train wheel and the train provided by the present embodiment can enable stress sustained by each component to be distributed uniformly when the wheel is subjected to alternating stresses, reducing cracks appearing from deformation and uneven stresses on the wheel.</p> |
