  • Running profile of railway wheel
    Patent number: 7669906
    Abstract: Wheels for goods wagons with small and large diameters, in addition to wheel sets equipped with wheels of this type for running gear, which are dependent on a highly passive radial positioning when negotiating curves and must remain stable at high speed. The inventive wheel profile is characterized as a result of the relatively large entry radius into the transition area from the running surface to the wheel flange by a low equivalent conicity. This enables a quieter running of the wheel set when the latter is travelling in a straight line. In curves, there is a sufficient rolling circle differential, permitting less wear and tear.
