Definitions

  • the present invention relates to the field of vehicle construction, in particular railway, and in particular the free end structures of all vehicles, and relates to an energy absorbing structure for such vehicles.
  • US-A-4 702 515 and DE-A-2 509 351 disclose deformable structures intended to equip motorized vehicles and absorbing, during an impact, by plastic deformation, a significant part of the energy of said shock.
  • Document DE-A-2 509 351 provides for the mounting of such an absorbent structure at the end of a vehicle.
  • the present invention aims to overcome these drawbacks by proposing an energy-absorbing structure, in particular for railway vehicles, allowing the total deformation of a space, while ensuring the protection of the passenger space.
  • the energy-absorbing structure in a vehicle in particular a rail vehicle, which consists of a zone deformable by dynamic plastic buckling of its structural elements, said zone being provided at at least one or at both ends of the vehicle, is characterized in that the deformable zone by dynamic plastic buckling of its structural elements forms a luggage compartment, an access platform, or the like, with the possibility of bilateral access, between a mobile end frame and a fixed frame delimiting the end of the passenger space, the mobile end frame being constituted by anti-collision uprights, by an upper crossmember and by a head crossmember, on which the coupling and the buffers are fixed and an anti-overlapping device guaranteeing a good distribution of forces.
  • the energy absorbing structure for vehicles in particular rail vehicles, shown by way of example in FIG. 1 of the accompanying drawings, consists of a zone 1 deformable by dynamic plastic buckling of its structural elements 2, said zone 1 being provided for at least one or both ends of the vehicle 3 and advantageously forming a luggage compartment, an access platform, or the like, with the possibility of bilateral access, between a mobile end frame 4 and a fixed frame 5 delimiting the end of the passenger area.
  • the movable end frame 4 is constituted by anti-collision uprights 6, by an upper cross member 7 and by a head cross member 8, on which the hitch 9 is fixed, as well as the buffers 10 and advantageously a device for anti-overlap ensuring good distribution of forces.
  • the coupling 9 and the buffers 10 are of known type and are shown in the accompanying drawing only by their center line.
  • the anti-overlapping devices are also not shown in the accompanying drawing and may in particular be of the type described in French patent application No. 91 11407.
  • the fixed frame 5 is advantageously in the form of a rigid hoop 11, bearing on the complete section of the vehicle 3 and connected to a lower cross member 12.
  • the latter may, in particular, form a pivot cross member of a railway vehicle.
  • the structural elements 2 are deformable in a predetermined direction and are formed by profiles forming, respectively, central beams 13 and stretchers 14 connecting the head cross member 8 of the movable frame 4 to the lower cross member 12 of the fixed frame 5 and leaves 15 connecting the upper cross member 7 of the movable frame 4 to the arch 11 of the fixed frame 5.
  • the deformable zone 1 is advantageously intended to carry out an energy absorption by plastic buckling of the structural elements 2 without having recourse to energy absorbers added to the structure of the vehicle.
  • the profiles constituting the elements 2 forming the central beams 13, the stretchers 14 and the leaves 15, are double-core profiles I and can be produced by extrusion and machining or by mechanical welding, the cutouts 16 being advantageously produced by machining.
  • the double-core profiles I constituting the elements 2 are shaped to deform by oriented plastic buckling, taking place by successive deformations in the longitudinal axis of said profiles.
  • the profiles forming the central beams 13, the stretchers 14 and the leaves 15, are advantageously made of a ductile material allowing a significant elongation and are provided, in the plane of their preferential deformation , of cutouts 16.
  • These cutouts 16 are preferably in the form of oblong holes. So the forecast holes 16 make it possible to weaken the profiles under a compression load and the existence of circular arcs at the ends of said cutouts 16 makes it possible to direct the plastic buckling of said profiles perpendicular to the longitudinal axis of said cutouts 16.
  • These profiles may have, if necessary, a prior plastic buckling of the walls corresponding to the longitudinal edges of the cutouts 16 by bending.
  • these sections 13 to 15 forming the elements 2 no longer fulfill the elastic function of the structure and are only intended to form an energy absorbing element and the peak in force from the start of the buckling is eliminated.
  • the elements 2 can be constituted by a juxtaposition and / or a superposition of several simple sections, the parts of which provided with cutouts 16 extend parallel and / or perpendicularly to each other, in the same plane or in parallel and / or perpendicular planes.
  • cutouts 16 extend parallel and / or perpendicularly to each other, in the same plane or in parallel and / or perpendicular planes.
  • the leaves 15 are assembled together by stiffening connection profiles 17 and the central beams 13 and the stretchers 14 are also assembled together by other stiffening connection profiles 18, these sections 17 and 18 being advantageously connected to sections 13 to 15 at locations corresponding to an interval between two cuts 16 and at a frequency of one or more cuts.
  • cutouts 16 are defined in order to guarantee a preferred plastic buckling order of the different stages, this order being the same for all the elements 2 connected together.
  • the central beams 13 and the stretchers 14 are advantageously embedded and bearing in the head cross member 8 of the movable frame 4 and in the lower cross member 12 of the fixed frame 5 and the leaves 15 are embedded and bearing in the upper cross member 7 of the frame mobile 4 and in the arch 11 of the fixed frame 5, their fixing being provided by welding, by riveting, by bolting or the like.
  • the invention it is possible to carry out an energy absorption, over a considerable length, at one end of a vehicle striking another vehicle or an obstacle, said energy absorption being carried out by progressive plastic buckling of said profiles. in the form of a reduction in length and with a limitation of the transverse deformation.
  • Such buckling is in particular made possible by means of a rigid mobile frame distributing the shock over all of the sections. This distribution can also be improved by the joint implementation of anti-overlapping devices.
  • the elastic behavior of the structure guarantees the resistance to the stresses to which the vehicle is subjected under normal traffic conditions, as well as during light impacts.
