company news about What is the composition of a railway wheel?

On the outer surface of the spokes of the railway wheel, the radii of the curve having the first outer radius and the curve having the second outer radius are 0.04 to 0.05 times the diameter of the rim. The radius of the curve with the third outer radius is 0.08 to 0.1 times the diameter of the rim. The radius of the curve with the fourth outer radius is 0.07 to 0.09 times the diameter of the rim. For the inner surface of the spoke, the radius of the curve having the first inner radius is 0.08 to 0.1 times the diameter of the rim. The radius of the curve with the second inner radius and the curve with the third inner radius is 0.06 to 0.08 times the diameter of the rim. The radius of the curve with the fourth inner radius is 0.04 to 0.06 times the diameter of the rim, wherein the first point is offset from the center plane in a direction away from the flange by no more than 0.08 times the width of the rim. The center point is offset from the center plane by a distance in the range of 0.35 to 0.4 times the rim width, and the second point is offset from the center plane in the direction toward the flange by no more than 0.1 times the rim width. The ratio of the thickness of the spoke at the first point to the thickness of the spoke at the second point is from 0.7 to 1.1, and the ratio of the thickness of the spoke at the center point to the thickness of the spoke at the second point is from 0.7 to 0.9. As a result, a low stress state of the wheel under the influence of different types of working loads is achieved, a minimum mass is achieved, a satisfactory degree of lateral deformation of the rim under thermal stress is achieved.
