Definitions

  • the present invention relates to a coupling joint between a first car and a second car of a vehicle, including rail, comprising at least two cars, said hinge being of the type comprising a first element adapted to be connected to said first car and a second element capable of being connected to said second car, means for translational displacement of said second element with respect to said first element in the event of an impact, and energy absorption means able to be arranged between said first and second cars.
  • Such articulation finds particular application when it is mounted between two cars of a railway vehicle each comprising two floors, because such two-stage cars have high weight compared to cars with only one floor.
  • the document FR 2,879,549 describes an embodiment of such a device, arranged at the front of the railway vehicle and not between cars.
  • Such a device is satisfactory for railway vehicles with few cars, for example up to eleven cars.
  • the energy absorbing devices provided at the front of the vehicles are no longer sufficient.
  • the articulations described in the document FR 2,716,149 are not adapted to be arranged between two cars comprising a single floor, because they are bulky. In particular, they require changing the entire morphology of devices allowing the passage of people from one car to another.
  • the object of the invention was therefore to provide a coupling joint between two cars, the bulk of which would be substantially identical to that of existing joints between two cars each comprising a single floor, and which would also include absorption means. impact in the event of a collision.
  • Such an arrangement of the energy absorbing means makes it possible to reduce the size of the joint and, associated with such a design of the first element, it allows a more compact construction than those known from the prior art.
  • FIG. figure 1 At the origin of the invention, it has been sought to replace a device 1 for articulation between two rail vehicle cars, illustrated in FIG. figure 1 attached to the end of a car 3, by another device according to the invention.
  • the other device must ensure not only the same functions of articulation between two cars and passage for travelers, but also a damping function in case of shock.
  • the device according to the invention which is also called coupling joint in the following description, must also not be more bulky than the device 1 illustrated in FIG. figure 1 , so that in practice the device 1 can be changed by a coupling joint according to the invention, without having to change the shape of the end 5 of the car 3.
  • the ends 5 of the cars comprise a wall 7, crossed by a gangway 9, of height such that a man of average size can stand there.
  • a frame 11 forming part of a corridor 12 between two cars.
  • the device 1 of the state of the art is designed to be fixed at least partially on the frame 11, in the lower part of the passage 9.
  • the device 1 comprises two substantially symmetrical lateral portions 13, each being designed to attach to an element of the frame 11, on either side of the corridor.
  • the device 1 also comprises a central portion 15, substantially flat, shaped such that it can be accommodated in a housing 17 formed at the end of a second car 19 and allow the passage of a man between the car 3 and the car 19.
  • the central portion 15 of the device 1 also comprises a through opening 21 adapted to cooperate with an opening 23 made in the housing 17 of the second vehicle 19, when the device 1 is positioned in the housing 17.
  • a ball (not shown) is inserted into the openings 21 and 23 when the device 1 is mounted in the housing 17 of the second vehicle 19 to ensure the articulation between the cars 3 and 19.
  • the housing 17 has a trapezoidal shape 25 to allow a slight pivoting of the device 1 between two edges 27 and 29 of the housing 17 around the ball joint, for example when the railway vehicle, including cars 3 and 19, enters a turn, so that cars register in curve.
  • the figure 3 shows an example of coupling articulation 31 according to the invention, able to replace a device 1 as described above.
  • the coupling joint 31 is fixed at least partially on the frame 11 of a vehicle 3, like the device 1.
  • the coupling joint 31 comprises a first element 33 comprising means for being connected to the car 3, partially illustrated in FIG. figures 1 and 3 , and in particular to the frame 11 of the car 3.
  • the first element 33 is made in one piece, for example steel, aluminum, composite material or other.
  • This one-piece construction of steel provides the joint with physical properties such that it can withstand, in particular, compression forces of substantially 1500 kN, tensile force of substantially 1000 kN and that it exhibits resistance to a vertical load. of substantially 1.3 CE.
  • the first element 33 comprises, more particularly, a central portion 36 adapted to form a bridge between the two cars 3 and 19, and two side portions 37 and 39 adapted to be fixed on the side walls of a gangway, planned between two cars.
  • the central portion 36 is shown in particular on the figure 5 .
  • the fastening means 41 comprise for example a plate 43 projecting from an edge of the central portion 36, and having through holes 45 able to accommodate fixing bolts, rivets and shear pins.
  • the central portion 36 is hollow, and has a substantially U-shaped cross-section. It thus has an upper wall 47, two lateral walls 51 and 53, and two strips 49, parallel to the upper wall 47, each extending from one of the side walls 51, 53 and forming a shoulder turned towards the inside of the central portion 36. It finally has a rear wall 52, connecting the side walls 51 and 53.
  • Such a configuration allows the first element 33 to provide a slide function.
  • the plate 43 is substantially in the extension of the upper wall 47.
  • the coupling joint 31 also comprises a second element 35 comprising means for being connected to the second car 19, illustrated in FIG. figure 2 .
  • the upper wall 47 has a through opening 55 which may include the attachment of energy absorbing means 56 between the first 33 and second 35 elements.
  • energy absorbing means 56 are known to those skilled in the art and are for example knives associated with bolts 57, as described in the patent application. FR 2,716,149 .
  • the upper wall 47 is substantially flat to support a floor plate, allowing the passage of people on the central portion 36.
  • the second member 35 has an outer shape complementary to the inner shape of the central portion 36, so that it is inserted in the portion 36, between the top wall 47 and the two strips 49, and can slide in the central portion 36 .
  • the first element 33 will be called slider 33 and the second element 35 will be called slider 35 in the following description.
  • the slideway 33 and the slider 35 provide a displacement in translation with respect to each other in the event of impact.
  • the device comprises means for holding the slider 35 in the slider 33 in a normal condition of use so as to prevent the displacement of the slider 35 in the slide 33 during normal operation of the railway vehicle.
  • the holding means are arranged to break in order to release the slide 35 and allow it to move in the slideway 33 so that the energy absorbing means 56 can fulfill their function.
  • the holding means are for example formed by the bolts 57 passing through the slide of the upper wall 47 to the strips 49 through the slide 35. Before an impact, the bolts 57 ensure that the slide 35 is held in position in the slideway 33. In the event of impact, the bolts 57 break, which releases the slide 35 which can thus move in the slideway 33.
  • the energy absorbing means 56 are fixed to the slider 35 or the slider 33 or both to the slider 35 and to the slider 33.
  • the energy absorbing means 56 are disposed at one end of the slider. slide 35 and bear against the rear wall 52 of the slideway 35.
  • the slider 35 Before a shock, the slider 35 is held in position in the slideway 33 by the bolts 57 calibrated in shear.
  • the bolts 57 break or are sheared, and the slider 35 moves in the slideway towards the rear wall 52 of the slideway 33.
  • the energy absorbing means 56 being disposed between the end of the slider 35 and the rear wall 52 of the slide 33, the displacement of the slider 35 causes the energy absorbing means 56 to collapse between the end of the slider 35 and the rear wall 52, which makes it possible to absorb a portion of energy due to shock.
  • the Figures 6 and 7 respectively show the position of the slider 35 in the slider 33 after an impact and before an impact.
  • the stroke of the slider 35 in the slider 33 is substantially 300 mm.
  • the slider 35 comprises an opening 59, substantially circular, to accommodate a ball (not shown) ensuring the maintenance of the coupling joint on the second car 19, as shown in FIG. figure 2 .
  • the patella allows, as explained above, the pivoting between the two cars 3 and 19 to ensure their registration curve.
  • the slider 35 also has at its free end 61 (that is to say the one on which the energy absorbing means 56 do not rest) hooking means 62 on a part of the end of the second car 19 (see in particular on figures 2 , 6 and 7 ).
  • the attachment means 62 are for example made in the form of a shoulder 62 engaging behind a piece 63 forming a hook, said piece 63 forming the aforementioned end portion of the second car 19, shown in particular on the figure 2 .
  • the two lateral parts 37 and 39 of the coupling joint each have a curved shape, respectively connecting the lateral edges 51 and 53 of the slideway 33 to the side walls 65 and 67 of the passageway 12.
  • Each of the lateral parts 37 and 39 is fixed on a side wall 65 and 67, respectively, by bolts 69 and rivets (see in particular the figures 4 and 5 ).
  • each end of the side portions 37 and 39 has a shape adapted to conform to the shape of the walls 65 and 67, so that each end of the side portions 37 and 39 is pressed respectively against each wall 65 and 67.
  • Each end of the side portions 37 and 39 also has through holes, so as to allow their attachment by means of bolts 69 and rivets.
  • the surplus mass resulting from the replacement of devices 1 by articulations as described above is substantially 430 kg on the entire railway vehicle, which does not impair (or little) the performance of rail vehicles to which such joints are intended.
  • the coupling joint according to the invention has a bulk substantially identical to that of a device 1 which it must replace.
  • the joint can be installed between each car of a railway vehicle or between certain cars only depending on the desired absorption performance.
