Definitions

  • the present invention relates to an intercirculation device for railway cars.
  • the qualities that an intercirculation device must have are essentially good general sealing, whatever the relative positions of the coupled cars, in particular in the curved parts of the tracks, and also good soundproofing.
  • an intercirculation device between railway cars comprising two corridors suspended from adjacent cars using means allowing universal movement of these corridors.
  • the means in question are, however, very complicated and are not applied to an intercirculation device between railway cars, in accordance with the preamble of claim 1, comprising a retractable half-corridor formed by a rigid ring connected to the body. of the car and provided with attachment means for making it integral with a similar ring connected to another car and with means for suspending this ring from the car.
  • the present invention aims to improve the suspension of such a rigid ring sealing device and to produce it in such a way that its bulk practically does not encroach on the interior space of the car and which lends itself easily to a coupling with a classic type car.
  • the suspension means comprise an upper bar fixed to the upper part of the ring and resting on two lateral supports fixed to the body of the car by means of an articulation allowing their rotation around of a vertical axis independently of each other.
  • the rotation of two lateral supports of the device allows the movement of the ring parallel to the direction of advance of the car.
  • the upper bar is fixed to the upper part of the ring by a reason allowing an angular movement of the bar relative to the ring in all directions.
  • the ring is able to rotate around the three axes of space.
  • the device comprises two control members mounted on the body of the car with coaxial rotation with the rotation of the lateral supports and coupled by a coupling bar connected to the lower part of the ring.
  • a differential rotation of the lateral supports and of the control members allows the ring to take an inclination which intervenes, for example, in the event of a difference in level of one car relative to the other.
  • the coupling bar is connected to the lower part of the ring by a link allowing a clearance between the bar and the ring in the direction of advance of the car. and in the horizontal transverse direction.
  • the coupling bar advantageously passes between the fork teeth fixed to the lower part of the ring, the spacing of the teeth being greater than the width of the bar.
  • connection allows the ring to perform, within certain limits, roll and pitch movements.
  • No rigid connection is provided between the ring and the coupling bar which in no case serves as a support means, the support function being only fulfilled at the level of the suspension of the ring on the upper bar.
  • the lateral supports as well as the control members are connected to the body of the car by means of elastic means protrusion tending to rotate them to project the ring out of the car.
  • the device also advantageously comprises a servo-assistance mechanism for bringing the ring in the retracted position towards the car against the elastic projection means.
  • the ring 1 is suspended from a substantially horizontal upper bar 2 and resting at its ends on lateral supports 3 themselves fixed to the body 4 of the car.
  • the ring 1 carries a bearing 5 in which is mounted a tube 6 by means of a pad 7 made of plastic material.
  • the bar 2 is slidably mounted in the tube 6, so that it can not only slide along its axis but also be oriented in all directions thanks to the plasticity of the pad 7.
  • Each lateral support 3 comprises a vertical tube 8 rotatably mounted in a bearing 9 fixed to the body 4 and resting, by means of a spring 11, in a ball bush 12 also fixed to the body 4.
  • each tube 8 On each tube 8 is fixed a support arm 13 extending horizontally and carrying at its end a ball bearing 30 in which the upper bar 2 is slidably mounted.
  • a symmetrical rotation of the lateral supports allows a translational movement of the ring 1 in the direction of advance of the car, that is to say perpendicular to the plane of Figure 1.
  • a lateral translational movement is also authorized by sliding the bar 2 in the bearings 30 and in the tube 6.
  • a vertical translational movement can be effected by variable compression of the spring 11.
  • the ring 1 By differential rotation of the supports 3, the ring 1 can be rotated about its vertical axis. It can also undergo a pitch rotation by rotation of the tube 6 around the bar 2, and a roll rotation by deformation of the plastic pad 7.
  • a control member 14 comprises a tube 15 coaxial with the tube 8 and resting on the latter by a shoulder 16.
  • the tube 15, which is thus free to rotate relative to the tube 8, carries at its lower end an articulated crank arm 17 to a coupling bar 18 which connects it to a symmetrical control member (not shown).
  • the bar 18 has at its ends elongated holes 20 allowing the deformation of the bar-crank arm system.
  • the position of the bar 18 is such that it does not touch the lower part of the ring 1, but that it is moved away from it by a distance d of the order of a few millimeters.
  • the coupling bar 18 cooperates with the ring only by means of forks 19 fixed on the ring, and the spacing of the teeth of these forks is significantly greater than the width of the bar ( Figure 6). This game allows a certain longitudinal movement of the bottom of the ring for a given position of its upper part.
  • each tube 15 is still fixed an arm of reminder 21 connected to the body 4 of the car by a tension spring 22 fixed to the body by means of a clip 23 located towards the outside of the body with respect to the common axis of the tubes 8 and 15 ( figure 3).
  • the support arms 13 are connected by springs 24 to fasteners 25 situated in a similar manner (FIG. 4).
  • the lateral supports 3 play a control role in the same way as the control members 14. However, their role as supports explains the terminology used.
  • An auxiliary shaft 26 is mounted vertically in bearings 27 fixed to the body and carries two arms 28, 29 provided with rollers to cooperate with plates 31, 32 fixed respectively on the return arm 21 and on the support arm 13.
  • the shaft 26 carries an arm 33 connected to the rod 34 of a jack 35 shown diagrammatically in FIG. 3 and arranged so as to rotate, by means of the shaft 26, the lateral supports 13 and the members of command 14 against the electrical projection means.
  • the servo-assistance mechanism comprising this cylinder (and a symmetrical cylinder) will be described later in detail.
  • Two membranes 36 of elastic material such as rubber extend vertically on the sides of the ring 1 (FIG. 8). Each is attached on the one hand to the front edge 37 of the ring and on the other hand to the body 4 of the car. These membranes have a convexity directed towards the outside of the car to cooperate with membranes 36a attached to a ring 1a of a car of the same type.
  • Pleated membranes 38 of similar material extend around the entire periphery of the ring and are attached on the one hand to the inner edge 39 of the ring and to the body 4 of the car. They are isolated from the interior of the car by partitions 41 which extend along lateral protective cheeks 42 articulated and applied to the interior walls of the ring by elastic means.
  • a hollow bead 43 of rubber substantially cylindrical, is fixed to the body of the car ( Figure 9) and extends above the upper part of the ring, to cooperate with a similar ring 43a of car of the same type.
  • a movable hatch 44 is articulated on the floor of the ring around an axis 45. It is liftable and its dimensions are sufficient to allow the passage of a man responsible for coupling the cars.
  • This hatch extends over the entire width of the ring and carries a bolt 46 arranged to engage, in the high position of the hatch, behind a latch 47 (FIG. 11) articulated around an axis 48 integral with the side wall of the ring.
  • This latch can be raised by means of a cable control under sheath 49 connected to a return 51 secured to a transverse shaft 52 ( Figures 7 and 9).
  • the shaft 52 is controlled in rotation by means of a connecting rod 53, shown by a single line for greater clarity, and a crankpin 53a, from a manual control lever 54.
  • the reference 51 also controls, by means of another connecting rod 55, the operation of two rotary hooks 56 intended to cooperate with bolts 57a fixed on the other ring 1 for the purpose of hooking the two rings one to the other.
  • the ring 1 On its side face not shown in FIG. 9, the ring 1 carries two bolts 57 corresponding to two hooks 56a of the ring 1a.
  • the ring 1 carries a centering cone 58 to cooperate with a complementary conical cavity 59a of the ring 1a.
  • the panel 1 On its other lateral face, the panel 1 carries an identical cavity 59 (FIG. 7) for cooperating with a cone, not shown, of the ring 1a.
  • a lever 54, a connecting rod 53 and a crankpin 53a are provided on each lateral face of the ring 1, the two crankpins being conjugated by the shaft 52 (FIG. 7). In this way, the coupler can simultaneously operate the levers 54 of the two cars.
  • a retraction lever 61 is wedged on the axis 45 of the hatch 44.
  • a similar lever (not shown) is wedged at the other end of the axis 45.
  • This lever has a curved shape to prevent, in its rotation, strike the coupling bar 18. It has an appendage 62 (FIG. 11) arranged to bear on a stop 63 integral with the body 4 of the car so as to maintain the ring in the retracted position against the projection means ( Figure 9). By rotation of this lever, this retainer disappears and the ring protrudes ( Figure 10).
  • a pawl 64 ( Figures 11 to 13) is integral with the hatch 44 and cooperates with the lever 61 so as to rotate it in the direction of retraction when the hatch is raised. Conversely, the pawl 64 does not drive the lever 61 when the hatch is lowered ( Figure 13).
  • the apparatus thus described operates in the following manner when it comes to coupling two cars of the same type (FIGS. 9 and 10).
  • the coupler raises the hatch 44 to obtain the space necessary for its operation.
  • the maneuvers carried out on the other car, which are identical and practically simultaneous, will not be described.
  • the raising of the hatch causes the rotation of the retraction lever 61 which, by bearing on the stop 63, causes the ring to retract towards the car.
  • the hatch is locked in the high position by the passage of the bolt 46 behind the latch 47, which allows the coupler to freely carry out its coupling operations.
  • the coupler turns the manual control lever 54 along the arrow F1, which causes, by the sheathed cable 49, the unlocking of the latch 47 and the release of the bolt 46.
  • the hatch 44 falls back down, driving the pawl 64.
  • the retraction lever 61 accompanies the pawl 64 and the ring moves into the protruding position (FIG. 10).
  • control levers 54 and the mechanism they drive constitute general control means, with multiple functions, used to control the hatch, the projection of the ring and its attachment.
  • a U-shaped ring 65 forming a closed yoke is articulated around an axis 66 integral with the wall of the ring and arranged to come over and hold a finger 67 of the lever 61. It is understood that the lever 61 thus retained will not accompany the pawl 64 when the hatch is lowered and the ring 1 will be kept retracted.
  • a rotary cam 68 maneuverable by a square 69, is arranged to act on a tail 71 of the latch 47 and cause it to be unlocked (FIG. 13).
  • This cam is integral with an arm 72 coupled by a connecting rod 73 to an arm 74 integral with the ring 65.
  • unlocking the hatch by means of the square 69 simultaneously causes the rotation of the ring 65 which covers the finger 67, and the hatch 44 lowers without authorizing the movement of the lever 61.
  • the arm 74 is provided long enough to serve as an end-of-travel stop for the movement of the ring 65.
  • This servo-mechanism comprises the two cylinders 35 mentioned above, the bodies of which are articulated on the body 4 of the car. They are connected by flexible pipes 75 to a pneumatic connector 76 fixed to the ceiling of the ring 1.
  • a flexible supply pipe 77 connects the connector 76 to a general pipe 78 of compressed air via a capacity 79, a non-return valve 81 and a shut-off valve 82.
  • this piping is extended by a loop 83 which returns to the connector to communicate with the piping 75 of the jacks, and on which is interposed a three-way distributor 84.
  • This distributor makes it possible to put the jacks in communication either with the general pipe 78 or with the atmosphere by means of a pusher 85 controlled by a cam 86 secured to one of the assembly hooks 56.
  • the pusher is arranged to admit compressed air into the jack when the hook 56 is in the high position in the direction of a retraction of the rod 34 in the jack, and to put the jack in the atmosphere when the hook 56 is in the low hooking position.
  • the servo-mechanism thus described operates in the following manner.
  • the coupler begins by operating the lever 54 in the direction of the arrow F2 to raise the hooks 56 and, thereby, cause the withdrawal of the ring. It can then raise the hatch 44 effortlessly since no elastic means no longer oppose it. This lifting of the hatch drives the retraction lever 61 which comes to bear on the stop 63 and remains locked in this position by locking the bolt 46 behind the latch 47. If any incident occurs on the air circuit compressed, the ring cannot therefore protrude and the coupler is safe from any accident.
  • the type of passage according to the invention is compatible with conventional cars known as “with beads”, where the passage is only formed by three hollow cylindrical rubber beads, upper and lateral.
  • the cooperation of these beads with the outer membranes 36 and with the upper bead 43 takes place in a satisfactory manner as shown in FIGS. 24 and 25.
  • the passage according to the invention can still be used as it is with an automatic coupling. In such an application, it can even be considerably simplified, the ring no longer having to be retracted.
