摘要： 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.

摘要： The invention concerns a vibration dampener device to reduce the noise of the moving railway wheels, which comprises two flat, annular, metal plates (16, 17), coupled and joined face to face and attached to the wheel, in front of the intermediate web or disk thereof, to cover the area of the wheel between the wheel hub and rim. Both annular plates have a central bore; they are positioned concentrically and one of them, the one with a larger diameter, is fixed to a peripheral plate supporting ring, whereas the other plate, with a smaller diameter, is fixed to a centre plate supporting ring. The two plate supporting rings are associated respectively with the wheel hub and rim by the anchoring of the annular plates to the wheel.

摘要： An axle of railway wheel sets and a corresponding method for the ultrasound inspection are described. A blind hole, coaxial to the axle and sized to accommodate an ultrasonic probe, is obtained in each end of the axle. Main holes are intended to accommodate the probe holder containing a plurality of ultrasonic transducers for the inspection of the axle from the inside of the hole. The main advantage is to facilitate the propagation of the ultrasounds without being subjected to the interference caused by the geometric discontinuities normally present at the ends of the axles thereby minimizing false positives in the readings of the echoes.

摘要： The present invention relates to a covering for protection against corrosion and knocks, specifically designed for railway wheel sets, consisting of at least three superimposed layers of different paints. The paints of the second and third layers also contain reinforcing fibres. Advantageously, the second layer of paint, i.e. the intermediate layer, provides a substantially elastic support for the third layer of the paint, i.e. the outer layer, which in turn is very resistant against knocks of ballast and ice.

摘要： The invention concerns a railway wheel with a mid-plane (S) perpendicular to the rotation axis, and a web (5) which extends along a central curvilinear line (AB) between a junction point (A) to the rim and a junction point (B) to the hub of the wheel. The web has an intermediate point (C) and two inflection points (D, E) between the intermediate point (C) and, respectively, the junction points (A and B). The two junction points (A e B) are located from the same part of the mid-plane (S) of the wheel, the intermediate point (C) of the web has a tangent to the central line (AB) that is parallel to the mid-plane (S) and is on the opposite side of said median plane (S), and the angle between the tangents to the central line (AB) of the web in the inflection points (D - E) is between 90 and 120 degrees.
