Definitions

  • an important object of the invention is to provide a railroad switch structure which reduces mechanical and flattening stresses upon the transit of railroad wheels at the point of the frog.
  • a switch structure which comprises at least one wide-V rail at a frog provided with at least one point and constituted by means of mutually assembled parts, characterized in that said at least one wide-V rail has, proximate to said frog, a raised region whose upper surface, for the rolling of the railroad wheels, is higher than the corresponding upper surface of said at least one point.
  • the railroad wheels advantageously do not use the end or the initial part of the point 3, which has a reduced cross-section, as resting surface, but rest on the part of the point whose cross-section is sufficient to withstand the flattening stresses, thus avoiding this problem.
  • the switch structure according to the invention is particularly advantageous in that it enormously limits maintenance interventions suitable to restore the original shape of the flattened point, with the consequence of a considerable saving of labor and materials during the technical life of the frogs of switches.
