Definitions

  • railway vehicles especially high-speed trains, are sometimes brought into contact with obstacles placed on the track.
  • the railway vehicles placed at the ends of the convoy are equipped, at the front, with a shock-absorbing device.
  • This device makes it possible to dissipate part of the kinetic energy of the vehicle.
  • it is known to transfer, during the retraction of the coupling, a portion of the kinetic energy to a sliding drawer mounted movable along the length of machinable bars arranged longitudinally and carried by the vehicle structure.
  • the drawer is equipped with cutting tools, commonly referred to as machining knives, for cutting the bars along their length to form chips.
  • the machinable bars are mounted under the chassis of the vehicle cab. They are secured by screws distributed along the length of the bars. The bars abut from their rear end on the rear portion of the frame.
  • the impact energy is dissipated only by machining the bars, which allows only limited energy absorption.
  • the object of the invention is to provide a shock absorbing device that allows greater energy dissipation.
  • the subject of the invention is a shock absorber device for a railway vehicle, of the aforementioned type, characterized in that the structure consists of a compressible element for the absorption of energy in the direction of the or each bar, and in that the or each bar is linked, from its front end, to said supporting structure, at a front end of the supporting structure opposite its connecting end for a concomitant movement of the or each bar and the front end of the carrier structure during compression of the carrier structure.
  • the invention further relates to a railway vehicle comprising a body and a shock absorber device as described above, attached to one end of the vehicle body from the fastening means of the carrier structure.
  • FIG. 1 On the figure 1 is schematically shown a front end of a railway vehicle equipped with a shock absorber device 10 according to the invention.
  • the railway vehicle comprises a body 12 supported by unrepresented bogies.
  • This box defines a cabin 14 for a driver.
  • the box 12 has at the front a glazed portion 16 forming a windshield and a solid wall 18 disposed under the windshield and on which is secured the shock absorber device 10.
  • the cabin 14 has a floor 20 below which is delimited a reserved space 22 adapted to receive certain movable elements of the shock absorber device after the railway vehicle has encountered an obstacle.
  • the shock absorbing device 10 is also used for the end-to-end connection of two railway vehicles.
  • the shock absorbing device comprises a carrier structure 32 connected to the solid front wall 18 of the vehicle structure from a rear end 34 equipped with a connecting flange 35.
  • the carrying structure 32 is able to transmit the traction / compression forces applied to the vehicle and thus forms a structural element of the vehicle. It consists of a metal box usually truncated pyramid gradually flaring from its front end 36 noted at its rear end 34 from which it is linked to the vehicle body.
  • the carrying structure 32 is formed of a set of metal sheets mechanically welded to each other so that the box formed is compressible axially by plastic deformation when bringing its two ends 34, 36 closer together. At its narrowed front end, the carrier structure has a front transverse plate 37.
  • the carrier structure 32 defines in its lower part a housing 38 reserved for the retraction of the drawbar 30. This housing opens through the front plate 37.
  • the shock absorbing device comprises an interchangeable modular absorber 40 secured to the front plate 37 of the supporting structure beyond which it projects forwardly. It is disposed above an opening 42 through which the housing 38 opens.
  • the modular absorber 40 consists of a plastically deformable metal structure formed of a set of welded sheets.
  • the axial compressive strength of the modular absorber 40 is less than the axial compressive strength of the carrier structure 32.
  • the modular absorber 40 is removably bonded to the front plate by screws.
  • the shock absorbing device further comprises a mechanism 50 energy absorption mechanism to allow the retraction of the drawbar 30 and the energy dissipation.
  • This mechanism comprises two machinable bars 52 extending on either side of the longitudinal axis of the vehicle and parallel thereto. They are each linked from a front end 54 to the front plate 37 of the supporting structure.
  • a drawbar 56 is slidably mounted along the length of the machinable bars 52.
  • the drawbar 30 is connected by a ball joint disposed at a first end on the slide 56. At its other end, the drawbar 30 comprises means 60 for mechanical coupling with a drawbar complementary to a other vehicle.
  • the machinable bars 52 extend generally horizontally. They are arranged in the retraction housing 38 of the drawbar formed inside the supporting structure 32. These bars are arranged in the extension of the space 22 formed below the cockpit 14 in the body 12 of the vehicle.
  • the two bars 52 are linked only at their front end 54 to the front plate 37. At their rear end 64, the two machinable bars are independent of the carrier structure 32 and the body 12 of the vehicle.
  • the bars 52 have at their front end 54 a connecting portion to the front plate 37 extended substantially along their length by a machinable section of greater diameter than the connecting section.
  • An intermediate chamfer connects the two successive sections.
  • Each bar 52 is engaged through an orifice formed in the front plate 37 and is retained therein.
  • a calibrated fuse element is interposed between the drawer 56 and the front plate 37. It ensures the initial retention of the drawer relative to the front plate.
  • This fuse element comprises a breakable section having a calibrated thickness allowing a break of this weakened section during a predetermined axial traction force applied between the slide 56 and the front plate 37.
  • the drawer is equipped for each bar 52 with a machining nut.
  • Each machining nut is engaged around a bar and comprises an annular machining profile formed of a crown delimiting according to its inner periphery cutting edges capable of machining the bar by cutting metal chips in it.
  • the shock absorbing device illustrated in the figures operates as follows.
  • the coupling bar 30 of the vehicle can be used to ensure the axial connection of two successive vehicles.
  • the forces are transmitted through the drawbar 30 to the drawbar 56, which transmits the forces to the front plate 37 of the carrier structure through the fuse element not yet broken. These forces are transmitted to the vehicle body coupled through the carrier structure 32.
  • the fuse element is selected sufficiently resistant to withstand the traction forces existing between two connected trains.
  • the drawbar 30 is, as is visible on the figure 1 , the first element of the shock absorbing device to come into contact with the obstacle placed in front.
  • the force applied by the obstacle on the drawbar 30 is transmitted to the drawbar 56 and the fuse element.
  • this force is greater than the predetermined breaking force of the fuse element, it breaks, thus allowing the slide 56 to slide along the machinable bars 52 away from the front plate 37.
  • the crown of the machining nut then enters the enlarged section of the machinable bar and causes the progressive formation of chips. The formation of such chips allows the dissipation of kinetic energy.
  • the drawbar 56 thus moves to the rear end of the bars 52 where it is held in abutment against a stop.
  • the obstacle comes into contact with the modular absorber 40, which compresses as shown in FIG. figure 2 to absorb some of the shock energy.
  • the carrier structure 32 After retraction of the coupling bar 30 and compression of the modular absorber 40, the carrier structure 32 is deformed axially by compression of the metal sheets constituting it as shown in FIG. figure 3 . During this compression, the bars 52, as well as the hitch bar 30 retracted engage in the reserved space 22 below the cabin 14.
  • the energy of the shock is dissipated on the one hand by machining the bars 52, and on the other hand by compression of the modular absorber 40 and the carrier structure 32.
  • connection of the bars 52 only from their front end on the front plate of the support structure allows them to retract into or inside the vehicle body 12, without damaging it.
  • the retractable bars they are not forks linked rigidly in the extension of the vehicle body, which could ride the obstacle and cause it to serious damage.
