The company develops a railway wheel that does not cause corrugation of the rail, including the hub, the spokes and the rim, the spokes connected between the hub and the rim and including the outer side facing the outside of the track and the inner side facing the inner side of the track, the outer side is vertical The curve formed on the cross-section of the wheel surface from the hub to the rim includes the first outer concave section, the outer convex section, the outer second inner concave section, and the outer third inner concave section that are tangent in sequence; the inner side is perpendicular to the wheel surface. The curve formed on the cross section from the hub to the rim includes the inner first outer convex section, the inner second outer convex section, the inner inner concave section, and the inner third outer convex section that are tangent in sequence. The railway wheel of the invention can eliminate the frictional self-excited vibration of the wheel-rail system, thereby eliminating the corrugation of the steel rail, and also has a beneficial effect on controlling the noise of the wheel-rail and preventing the breakage of the fastener spring and the bolt; the subway line will no longer need the rail. Grinding the car, the service life of the rail will be greatly improved, and the fracture of the rail fastener will be greatly reduced.
