  • the sole 9B connected to the body of the adjacent vehicle B, is composed of several elements welded together.
  • This sole 9B has a vertical cylindrical rim 10 to which is fixed, by bolts such as 11, a part circular of triangular cross section 12 supporting the O-ring element 13.
  • the element O-ring 13 is, for example, composed of 14 metal plates sandwiched between layers of elastic material 15.
  • a frustoconical plate 16 constitutes the bearing surface of the periphery of the lower part of the O-ring 1.
  • means of energy absorption 3 are arranged between the part upper part of the O-ring 1 and the upper part of the support piece 9 facing it. These means energy absorption 3 are arranged between the second external cylindrical surface 1B of the toric part 1 and the surface 20B of vehicle B facing the second surface 1B.
  • shearing means 22 cooperating with longitudinal translation means 23 are arranged between the support piece 9 and a support arm 24.
  • the support arm 24 is connected to vehicle B.
  • the means of shear 22 hold the support piece 9 integral longitudinal translation means 23.
  • the means of longitudinal translation 23 are fixed to the support arm 24.
  • the ends of the longitudinal translation means 23 and the support piece 9 have surfaces such that they constitute a transverse stop 25.
  • This stop has the function of limiting the stroke of the support piece 9 along the support arm 24 and prevent the bodies of vehicles from dissociate when pulling the train following the rupture of the shearing means 22.
  • the O-ring 1 is non-deformable and one and the other of its ends forms a buttress.
  • the O-ring 1 is calibrated according to the type of railway material rolling on which it is mounted. For example, the holding of this toric part varies from 20 kN to 3000 kN.
  • the O-ring can be made of steel, alloy Titanium, aluminum alloy or composite materials.
  • the energy absorption means 3 mounted at the end of vehicle B absorbs energy. This energy absorption can be done when the vehicles are aligned or when the vehicles are on a curve, but also when recesses and bumps in the track profile.
  • the energy absorption means 3 are elements intervening only when the force values longitudinal exceed the values of the normal forces of service.
  • the means of energy absorption can be made from materials with coefficients high elongation and a large difference between its limit elastic and its breaking limit so as to absorb the maximum energy without risk of rupture from the start of shock.
  • the energy absorption means 3 are structures of ordinary steel, of steel stainless, aluminum alloy, forming a structure in sheets or honeycombs, or a structure combining the steels or alloy mentioned.
