Abstract: A railway wheel includes a rotation axis and a supporting disk which can be attachable on an axle at the rotation axis. The supporting disk can be coupled with a wheel rim for rolling on a rail. The wheel provides damping means of the rim with respect to the supporting disk which include elastic elements interposed between the disk and the rim, aside with respect to the median plane of the wheel. Each elastic element has its own geometrical axis and includes a first face facing the median plane of the wheel and a second face opposed thereto and facing the opposite part with respect the median plane of the wheel, so that the elastic element extends its thickness between the two faces. The first and second faces of each elastic element have the same concavity or convexity when considered in cross section in any plane containing the geometrical axis.
