Definitions

  • the present invention relates to a railway vehicle comprising a body and two bogies, each of which is connected to the body by a single connecting rod articulated between a point of the longitudinal axis of the bogie close to the end of the body and a point of the longitudinal axis of the body close to said end, one of the connecting rods working in compression while the other working in traction, and vice versa, depending on the direction of travel.
  • a railway vehicle comprising a body and two bogies, each of which is connected to the body by a single connecting rod articulated between a point of the longitudinal axis of the bogie close to the end of the body and a point of the longitudinal axis of the body close to said end, one of the connecting rods working in compression while the other working in traction, and vice versa, depending on the direction of travel.
  • FIGS. 1 and 2 show how this result is achieved.
  • FIG. 1 represents the behavior of such a vehicle for a locomotive having the direction of travel considered, illustrated by the arrow M.
  • the bogie 2 is the front bogie and it pushes the body 1 by means of the connecting rod 7'-9 ' , this connecting rod being disposed at the front of the front bogie in 7 ', a point of articulation to the bogie 2, and in 9', a point of articulation with the body 1.
  • the force F transmitted to the bogie 2 in 7 'by the rod 7'-9' acts on it in compression.
  • the force F has a longitudinal component L equal to the motor force of the bogie 2 and a transverse component T balanced by reactions R1 and R2 of the track on the axles which are in the opposite direction to the normal reactions S1 and S2 due to slipping on the rail and therefore come to reduce its value.
  • the wear of the locomotive flanges is therefore low.
  • 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 in the opposite direction to the reactions S3 and S4 due to the sliding of the axles on the rail and therefore always come to 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 4'-6 'rod is arranged this times 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 rods 7'-9 'and 4' work in this case both in compression and in traction. This requires oversizing the cross section of the connecting rods to allow them to respond to compression as well as tensile stresses.
  • the invention aims to allow the use of connecting rods of moderate cross section in a railroad vehicle each bogie of which is connected to the body by a single connecting rod operating in traction or in compression so as to reduce the wear of the flanges of the wheels. .
  • the rail vehicle according to the invention is characterized in that its connecting rods between body and bogie are full, at least at their two ends, and of cross section progressively increasing from their ends.
  • the articulation of said connecting rod does not include any play.
  • said connecting rod is metallic.
  • said connecting rod is full at its two ends and hollow in the form of a cylindrical tube in the middle.
  • 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 part 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 has 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 rests 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 ensure the transfer of 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.
