Definitions

  • the present invention relates to the field of the construction of railway vehicles fitted with shock buffers, in particular safety devices intended to avoid overlapping, that is to say making it possible to limit the vertical movements of a vehicle relative to the other in the event of an accident, and relates to a device for overlapping and energy absorption for such railway vehicles.
  • an energy absorption device for railway vehicles is known, essentially constituted by a pad mounted to slide so as to be able to sink elastically into a support, which is itself fixed. at the end of the chassis with the possibility of sliding, after breaking of its fixing bolts, in order to retract inside the chassis.
  • Such a device does not, however, prevent an overlap of two vehicles, because it does not provide any means of maintaining said vehicles in alignment by removing their latitude of lateral and / or vertical movement.
  • the present invention aims to overcome these drawbacks.
  • a device for anti-overlapping and energy absorption for rail vehicles comprising two shock buffers intended to cooperate with each other and integrated in a sliding manner in two supports, characterized in that the supports are a male support fixed at the end of the chassis on one of the vehicles and a female support fixed at the end of the other vehicle, the male support penetrating into the female support when the shock pads sink into the respective supports during a shock.
  • the anti-overlap and energy absorption device for rail vehicles comprising two shock buffers 5, 6 intended to cooperate with each other and integrated in a sliding manner in two supports 1, 2, is characterized in that the supports 1, 2 are a male support 1 fixed at the end of the chassis on one of the vehicles 3 and a female support 2 fixed in end of the other vehicle 4, the male support 1 penetrating into the female support 2 when the shock buffers 5, 6 sink into the respective supports 1, 2 during an impact.
  • the device according to the invention is in the normal circulation position, the buffers being free.
  • the device directly integrates the shock buffers 5 and 6 in a sliding manner in the corresponding male 1 and female 2 supports.
  • the buffers 5 and 6 are secured to the supports 1 and 2 by means of fusible fasteners 7, such as shear rivets, pressure screws 8 being mounted opposite one another in order to eliminate the mounting clearance and to prevent the fasteners 7 from working in traction.
  • the supports 1 and 2 for sliding guide of the shock buffers 5 and 6 contain, behind said buffers 5 and 6, energy absorbers 9.
  • the fasteners 7 shear and the buffers 5 and 6 sink against the energy absorbers 9 allowing a stroke C 2 of each buffer such that the two vehicles 3 and 4 are in contact.
  • the height of the tray 10 of the pad 5 guided in the male support 1 is reduced compared to that of the tray 11 of the pad 6 guided in the female support 2, so that the size of the latter can be reduced.
  • the female support 2 has a conical opening, the opening angle of which is such that it allows maximum vertical displacements d, with simple contact at the level of the plates 10 and 11 during the total compression of the buffers 5 and 6 over their respective stroke length C 1.
  • the opening angle of which is such that it allows maximum vertical displacements d, with simple contact at the level of the plates 10 and 11 during the total compression of the buffers 5 and 6 over their respective stroke length C 1.
  • the device according to the invention allows direct recovery by the supports 1 and 2 and not by the buffers 5 and 6 of the vertical forces in the event of a sudden approach of two vehicles.
  • all standards in traffic law relating to the coupling, the gangway, the Berne rectangle, the flange and the half coupling, etc., as well as the passage of the coupler under the buffers may be respected.
  • the device according to the invention also provides, in the event of an impact, an energy absorption function until the structures of the two vehicles are in contact.
  • the device according to the invention can be adapted, subject to minor modifications, to existing equipment.
  • the invention it is possible to produce a device for overlapping ensuring, in addition, in the event of shocks an energy absorption function until the structures of the two vehicles are in contact.
