Definitions

  • the present invention relates to a bogie in particular for maintaining the maintenance of freight wagons.
  • a bogie consists essentially of longitudinal members which are joined in the vicinity of their center by a pivot crossbar.
  • the longitudinal members comprise, in their central part, a zone of great thickness which, in a conventional way in material resistance, is provided with a light making it possible to reduce the weight of this spar while conferring on it sufficient rigidity.
  • a bogie according to the state of the art is represented on the figure 1 . It comprises two longitudinal members 2 which are joined near their middle, at their light, by a pivot crossbar 4. At each of their ends, the longitudinal members 2 are mounted on axle boxes 6, the latter allowing The bogie shown further comprises shock absorbers, brake systems, a thrust block or other elements which are well known to those skilled in the art. It also includes elements, also well known to those skilled in the art, which have been omitted not to unnecessarily burden the figure, such as in particular the head rails connecting one end of each spar or the side members, parallel to the side members and connecting the head rails to the pivot crossbar.
  • This pivot crosspiece comprises an upper sole 12 and a lower sole 14 whose ends are interconnected by spacers 18-24.
  • the soles are of generally rectangular shape. They have a large side, the length of which is the order of 2 m, whose direction is perpendicular to that of the longitudinal members, and a small side, whose length is of the order of 1 m, whose direction is parallel to that of the longitudinal members.
  • the thickness of the soles is of the order of 15 mm.
  • the upper sole 36 comprises, at each end of its long sides, an ear 26, 28, 30 and 32 intended to be connected to a spacer 18, 20, 22 and 24.
  • the lower sole 38 comprises similarly ears 26 ', 28', 30 'and 32'.
  • the ears are generally square with a side of the order of 10 cm, one of the sides being partly curved to come tangent the long side of the sole.
  • An object of the present invention is to overcome the disadvantages of the prior art.
  • the subject of the present invention is a bogie, in particular for a goods transport wagon, comprising a pivot cross-member comprising an upper sole, a lower sole and spacers joining the soles together, in which at least one of the soles is rectangular in shape and in which the spacers are fixed on the long sides of said at least one rectangular sole.
  • the pivot crosspiece according to the invention is particularly interesting in that its manufacture is easier and requires less time than a manufacture according to the prior art.
  • a second advantage of the invention is a reduction of the material necessary for the manufacture of the cross pivot.
  • each sole of the pivot crossbar is rectangular.
  • the spacers are fixed by welding to the soles of the pivot crossbar.
  • the spacers have a generally U-shaped whose ends flare at their attachment to each rectangular sole.
  • the bogie comprises two beams each provided with a light, the periphery of this light receiving an edge of each sole and an edge of each spacer.
  • the spacers have a variable thickness in their longitudinal direction.
  • the thickness is made variable by machining to optimize the stresses.
  • the spacers have a thickness equal to that of the lower flange of the pivot crossbar.
  • the crossbar pivot 34 according to the invention shown on the figure 3 has a similar shape, even identical, to the pivot crossbar 4 according to the prior art shown in the figure 2 . It differs, however, fundamentally in the form of the elements that constitute it.
  • At least one sole of the upper sole 36 and the lower sole 38 of the cross member 34 is of rectangular shape.
  • the upper sole 36 and the lower sole 38 are rectangular, with a length of the order of 2 m, a width of about 80 cm and a thickness of about 15 mm.
  • the soles are joined together by spacers 40, 42, 44 and 46 of rectangular shape and which are folded on themselves so that one end of a spacer can be fixed on one end of a large side of the upper sole 36 and the other end of this spacer can be fixed on the corresponding end of the lower sole 38.
  • the fixing between the spacers and the flanges is preferably performed by welding.
  • a spacer of a pivot cross member according to the invention it is necessary to use spacers of greater length, a spacer of a pivot cross member according to the invention to have a length equal to that of a spacer of a pivot cross member according to the prior art plus the length of two ears.
  • the balance sheet in raw material is in favor of the pivot cross member according to the invention, the gain being of the order of 100 kg (corresponding to the removal of the four blanks).
  • the spacers are rectangular. It may be advantageous, to better stiffen the cross pivot, to flare the spacers in their part fixed to the flanges. In other words when moving in the longitudinal direction (parallel to the long sides of the spacer), the width of the spacer gradually increases near the short side of the spacer.
  • this flare may be such that the edge of a large side of the spacer comes tangent the edge of a large side of a sole when the spacer is attached to the sole (see area 48) .
  • the bogie according to the invention can be of any known type, and in particular according to the bogie represented on the figure 1 , in respect of elements other than the pivot crossbar.
  • the beams of the boggie comprise, in their central part, a thick area which is provided with a light to reduce the weight of the spar while giving it sufficient rigidity, the periphery of this light receiving an edge of each sole and an edge of each spacer.
