Definitions

  • the object of reference in the invention covered by this Patent comprises an "Elastic tie plate for railway track”.
  • the supporting structure for railway lines comprises generally, from bottom to top: a layer of ballast (crushed stone) which is extended over the roadbed for laying and supporting upon it the crossties; the crossties themselves (of wood, iron, concrete or mixture thereof) on which the rail rests; and the latter, whose shape is defined by the head (upper widening on which sits the rim of the wheels and is guided by its flange), web (vertical union between head and foot) and base (horizontal plane seated on the crosstie).
  • ballast crushed stone
  • the fastening of the rail to the crosstie is done according to a great many systems and with different means however, in general, it can be considered to consist of: an element for tightening on the base which can be of the plate or clip type; an element for anchoring on the crosstie into which element is inserted a bolt or screw spike (large screws which are mounted in pairs, running through symmetrically arranged holes made for this purpose in the flanges of the base, on both sides, and which are inserted or removed with large box spanners); and a butt element or piece, generally at the side, to withstand the forces produced in this direction through the guidance of the wheel flanges by the rail head.
  • a bolt or screw spike large screws which are mounted in pairs, running through symmetrically arranged holes made for this purpose in the flanges of the base, on both sides, and which are inserted or removed with large box spanners
  • a butt element or piece generally at the side, to withstand the forces produced in this direction through the guidance of the wheel f
  • complementary elastic means mention can be made of: springs inserted between the head of the screw spike and the base of the rail; clips with extra elasticity due to their shape or constitution; and seating plates inserted between the base of the rail and the top side of the crosstie, in the retention area.
  • the elasticity of the latter also depends on their shape (geometry of their design) and their constitution (technical properties of the material employed in their manufacture).
  • the effectiveness of the elastic tie plates is of major importance, not only for the better performance of their primary function of damping vibrations but also because, through this action, they contribute to the conservation, on one hand of the roadbed, by reducing the forces applied to it, and on the other hand of the crosstie, through the same damping action of the fastening clips or plates, by removing to a great extent or at least reducing the fatigue they suffer from the cyclic forces produced by the movement of the rolling stock, especially from high speed convoys.
  • the purpose of the invention which constitutes the object of this Patent, consists in obtaining a tie plate for railway track whose technical properties, and particularly its elasticity, improve the features of those known and employed to date.
  • the plate has a thickness of 7 mm and is generally rectangular in form, which is necessary for its application, having the following geometrical and functional characteristics:
  • the flexible tie plate for railway track which is the object of the Patent, is of a generally rectangular shape and is moulded using an ether-ester thermoplastic elastomer.
  • Said projections (1) are arranged in order in rows and columns, with their upper face coplanar with and positioned in the longitudinal direction of the rail, the base of which rests on them.
  • the plane defined by the upper faces of the projections (1) reaches as far as the plate edges (2) perpendicular to the rail, whilst the other two edges (3), parallel to it, are situated in a slightly lower plane, forming rectangular bands (4) parallel to each side, which contribute to the reduction of rated pressure when, through live loading on the rail, elastic deformation takes place of the upper plane of the projections (1).
  • projections (5) On its lower face there are a number of projections (5) of like shape, arrangement and positioning as the projections (1) on the upper face, though slightly smaller, arranged with respect to them so that their geometric centre coincides with the centre of the spacing between every four projections (1).
  • the plate sides perpendicular to the rail extend below said plate, on both sides, forming discontinuous lips (6), in the form of a truncated pyramid, said lips fitting externally over the crosstie to prevent the plate being displaced in the longitudinal direction of the rail, and facilitate its being centrally mounted.
  • the plane defined by the upper faces of the projections (5) reaches the four edges of the plate, forming a rectangular frame which, on each of the sides parallel to the rail, is extended in the form of a flat lip (7), whilst on the sides perpendicular to it and on the inside of the frame, corresponding rectangular bands (8) appear on an intermediate plane between that of the upper faces of the projections (5) and that on which they rest, said bands complying with the same mechanical objective as the bands (4) of the upper face.
