Definitions

  • the present invention relates to a railway vehicle comprising a body and two motor bogies, each of which is connected to the body by a single connecting rod, one of the connecting rods working in compression while the other works in traction, and vice versa, according to the direction of travel.
  • Document DE-A-2 604 769 describes a railway vehicle with a motor bogie connected to the body by a single connecting rod of constant cross section, the latter ending on the side of the bogie by an elastic ball joint and on the side of the body with a articulation with elastic discs.
  • Document GB-A - 2,055,079 describes a railway vehicle with two motor bogies, each of which is connected to the body by a single connecting rod, one of the connecting rods working in compression and the other in traction, and vice versa, depending on the direction of travel. But each of these connecting rods is articulated between a point on the axis of the bogie distant from the end of the body and a point of the body relatively close to the middle of the latter.
  • the object of the present invention is to reduce wear on the flanges of the wheels in the course of curved tracks.
  • each of the connecting rods is articulated between a point on the longitudinal axis of the bogie close to the end of the body and a point on the longitudinal axis of the body close to said end .
  • the articulation of the connecting rod does not include any play.
  • the articulation between the connecting rod and the chassis formed either by the body or by the bogie comprises an axis integral with said chassis and a ball joint integral with the connecting rod cooperating with each other.
  • the articulation between the connecting rod and the chassis constituted either by the body or by the bogie comprises elastomer damping elements.
  • the connecting rod is full, at least at its ends, and of cross section progressively increasing from its ends.
  • it is hollow in the form of a cylindrical tube in the middle.
  • Figures 1 and 2 show the distribution of forces in a motor vehicle according to the invention traveling a curved track.
  • FIG. 3 represents a schematic side view of a connecting rod according to the invention and of its articulations.
  • the rear bogie 2 ' As for the rear bogie 2 ', it pulls the body 1 by means of the connecting rod 4'-6' disposed at the rear of the rear bogie 2 '.
  • the force F transmitted by the connecting rod on the body acts this time in traction but the reactions R3, R4 of the track on the axles and balancing the transverse component T are of opposite direction to the reactions S3 and S4 due to the sliding of the axles on the rail and therefore always reduce its value.
  • the bogie 2 is the front bogie and it pushes the body 1 by means of the connecting rod 4'-6 '.
  • the rod 4'-6 ' is arranged this time at the front of the bogie before 2', and it works in compression.
  • the bogie 2 is the rear bogie and it pulls the body 1 by means of the connecting rod 7'-9 '.
  • the rod 7'-9 ' is disposed at the rear of the rear bogie 2 and it works in traction.
  • connecting rod 100 connecting the points of articulation 7 'and 9' or 4 'and 6'.
  • the connecting rod 100 is dimensioned so that it can withstand compression or tensile forces and for this the section of the connecting rod 100, metallic and solid, is greater in the middle of the connecting rod than at the ends, the variation in the section being progressive.
  • the connecting rod 100 has at its ends ball joints 11 which cooperate with and are crossed by the axes 12 and 13 arranged in fixed yokes 14 and 15 respectively in the body and bogie chassis. It should be noted that instead of ball joints such as 11, it is possible to envisage orifices in the ends of the connecting rods ensuring an equivalent role which is to transfer the forces from the yoke to the connecting rod or vice versa and to allow rotation of the connecting rod around of the axis.
  • the axes 12 and 13 have reverse stop heads 16, 17 in order to facilitate their installation, but heads arranged in the same direction can also be envisaged.
  • a connecting rod 100 ′ represents a variant of the connecting rod 100.
  • the connecting rod 100 ′ is made up of metal ends 18 and 19 of progressively increasing sections and solid and of a metallic and hollow central portion 20 in the form of a cylindrical tube, for example, welded to the ends 18 and 19 by welds such as 21.
  • FIG. 5 we see an articulation such as 7 'remarkable in that it comprises elastomer elements which have the advantage of absorbing shocks.
  • a connecting rod 100 (or 100 ') passing through a fixed part 22 secured to the body or bogie chassis.
  • the fixed part 22 includes an orifice 23 through which the end of the connecting rod 100 passes.
  • On this end of the connecting rod 100 are mounted two elastomer elements 24, 25 held in position by two metal stops 26, 27; one of the stops 26 is supported on a shoulder 28 of the connecting rod 100, the other stop 26 is supported by a washer 29 on a nut 30.
  • the elastomer elements 24, 25 provide the transfer forces from the connecting rod 100 to the fixed part 22 or vice versa.
  • the applications of the device of the present invention are in the field of fitting out bogies and rail vehicle chassis as well as their connections.
