Definitions

  • the present invention relates to a railway car bogie, comprising a chassis and two steerable axles.
  • the classic, non-orientable bogies consist of a chassis and two axles rigidly connected to this chassis.
  • the two axles thus form a non-deformable rectangle.
  • These bogies make it possible to drive at very high speeds while retaining good stability, but, on the other hand, they do not allow correct registration of the axles in small radius curves.
  • the wheels and rails therefore show significant wear.
  • An object of the present invention is to produce a bogie stabilized at high speed.
  • Another object is to make a simple implementation bogie.
  • the bogie of the invention which comprises on each side, two connecting rods each connected to a frame integral with the axle box and to a central lifting beam articulated on the chassis.
  • These two connecting rods introduce, between the two axles, a very low angular stiffness in curve (axles in opposition) and a high angular stiffness in alignment which stabilizes the behavior of the mechanical system.
  • the subject of the present invention is a bogie of railway vehicles, comprising a chassis and two orientable axles each mounted on a frame, each axle being carried by two axle boxes linked to a frame, each frame being connected to the chassis by via primary suspension springs and a vertical link, the two frames being interconnected by two diagonal bars, characterized in that it comprises, on each side of the chassis, two connecting rods each connected to a frame and to a central lifting beam articulated on the chassis.
  • the bogie comprises a chassis 10, two axles 20, two frames 30, two links 50, four springs 40, two transverse bars 71, 72, two spreaders 60 and four links 55.
  • Each axle 20 receives a guide frame 30 composed of two longitudinal bars 31 and a transverse bar 32.
  • Each longitudinal bar 31 is fixed to an axle box 25.
  • the assembly thus produced is connected to the chassis by means of two springs 40.
  • Each guide frame is also connected to the chassis by a vertical connecting rod 50.
  • the two frames 30 are interconnected by two diagonal bars 71, 72, these bars each being connected to the two transverse bars 32 of the frames 30. These two frames each receive two connecting rods 55, each articulated to a lifting beam 60 itself articulated on the chassis.
  • FIG. 2 shows, on the left side, a complete half-view from above, and on the right, a half-view from above comprising cutouts.
  • the chassis 10 composed of its two longitudinal members 11, a connecting tube 12 and two longitudinal stretchers 13 connecting the two tubes 12.
  • the two frames are interconnected, at their crossbar 32, by two diagonal bars 71, 72 mounted on a hinge.
  • Each frame 30 is connected to the chassis by means of its transverse bar 32 and a link 50 drawn in broken lines in FIG. 3, on the right side.
  • Each frame 30 is also linked to the chassis via its transverse bar 32 and two connecting rods 55 each attached to one end of the bar 32.
  • the two connecting rods located on the same side of the bogie therefore connect a different frame, and they are articulated to a spreader 60, such a connecting rod 55 and a half spreader being clearly visible on the left side of FIG. 3.
  • the crossbar 32 of a frame 30 carries, as can be seen in Figure 2, right side, and in Figure 3, right side, two supports 33 on which is fixed a tube 34, this tube carrying two braking devices 23, each device being actuated by a cylinder 24.
  • FIG. 2 also shows a torsion bar 18 and a pivot 14 for driving the box-chassis of the bogie, on which is articulated a lifting beam 19A connected to the two longitudinal stretchers 13 by means of two links 19B.
  • Figure 3 also shows the bar 18, the pivot 14 and the rods 19, but also the primary and secondary suspensions, left side in the figure.
  • the primary suspension comprises four springs 40 each arranged between an axle box 25 and a beam 11, and four shock absorbers 41.
  • the secondary suspension comprises two groups of vertical springs 15, two vertical shock absorbers 16 and two anti-yaw dampers 17, a shock absorber 17 being of course connected to the bogie chassis as shown in FIG. 2, and to the vehicle body .
  • the connecting rods 55 - lifting beams 60 transmits the longitudinal forces which appear between the bogie chassis and the axles, and stabilizes the axles in alignment because it avoids any yaw movement.
  • the low shear stiffness of the springs 40 allows good radial registration of the axles.
  • the diagonal bars 71, 72 do not hinder the radial registration of the axles, the connecting rods 55 - spreaders 60 assembly then opposing no resistance to this movement while continuing to perform its function of transmitting the longitudinal forces.
  • the recovery of the transverse forces between the bogie chassis and the axles is ensured by the shear strength of the springs 40 and by transverse stops which limit the clearance in the event of excessive forces. These stops are produced in the form of plates on which the axle boxes abut. The geometrical place of the recovery of the transverse forces being very close to the axis of the axle, these generate no torque tending to modify the orientation of the axles.
