Definitions

  • the present invention concerns a railway bogie equipped with a gauge varying system, and a railway vehicle comprising such bogie.
  • a bogie is a component of a railway vehicle which is provided with sets of wheels and carries the carbody of the vehicle above the rails.
  • bogies are designed for railway lines having a standard or main reference gauge; for example, in central Europe the predominant standard gauge measures 1,435 mm.
  • railway lines have different gauges; for example, in topographically challenging area, such as mountains, smaller gauges are sometimes used, e.g. gauges of 1,000 mm, usually referred to as the metric gauge.
  • patent document CH 703 173 A2 describes a solution where a bogie comprises two half frames supporting each a corresponding set of wheels, and wherein their mutual distance can be varied by means of two lateral arms protruding laterally outside the aligned set of wheels.

  • first and second half-frames 10 and 20 are movably connected to each other by means of at least one telescopic bar 15.
  • the bogie 100 comprises a first telescopic bar 15 and a second substantially identical telescopic bar 25 (only partially visible in figures 2-4 ), which are positioned, with reference to the travel direction (X), on a front part and on a rear part of a transverse bolster 30 of the bogie 100.
  • the transverse bolster 30 is suitable to be connected to a carbody (not illustrated in the figures) of a railway vehicle; for example, according to solutions well known in the art and therefore not described herein in details, the connection is realized using one or more suspensions comprising, inter alia, an air spring 31 and a coupling pivot 32 positioned at the central part of the bolster 30.
  • the transverse bolster 30 is movable, together with the carbody once connected therewith, between a lowered position ( figure 1 ) where the bolster 30 rests on and is locked to the first and second half-frames 10, 20 at a first mutual position thereof, and a raised position (see figures 2-4 ) where it is unlocked from and is lifted above the first and second half-frames 10, 20 from the first mutual position.

  • the second distance is longer that said first distance.
  • the third and fourth pivots 203 and 204 slide inside and are guided each by the profile of the corresponding guiding rails; in particular, the presence of the four guided pivots 201, 202, 203 and 204 prevents undesired rotations of the bogie 100 around the vertical axis (Z) and ensures a steady movement of the half-frames 10 and 20, thus eliminating, or at least reducing, the likelihood of their jamming.
