Definitions

  • the present invention relates to a device for orienting a bogie to an axle in a curve.
  • motor or towed vehicles were mounted on two axles arranged pependicularly to the longitudinal median plane of the vehicle, and fixed orientation relative to this plane.
  • the invention of the two-axle bogie made it possible to produce longer vehicles, while limiting the angle of attack of the axles relative to the track; indeed, the bogie allows a certain orientation of these, from which it follows that the angle of attack is reduced and becomes a function of the length of the bogie and no longer of that of the vehicle.
  • Document FR-A-1 104364 has proposed a device for orienting a bogie with an axle in the radial direction of the track in a curve, applicable to one end of a first vehicle adjacent to a second vehicle, comprising two fixed anchor points arranged on either side of the longitudinal axes of said first and second vehicles at a distance "a" from each of these axes, the first fixed anchor point being on one end of said first vehicle, the second fixed anchor point being on the opposite end of said second vehicle, and on each bogie two articulation points arranged on either side of each of the longitudinal axes of the two vehicles at a distance "b" from each of these axes, greater than the distance "a”, and respectively called first and second points of articulation for said first vehicle, and third and fourth points of articulation for said second vehicle, and at least four connecting rods, the second connecting rod connecting said fourth articulation point at said first anchoring point, the third connecting rod connecting said first articulation point to said second anchoring point, said first and fourth connecting rods being parallel
  • Such a device makes it possible to cross radius curves which can go down to 80 meters, provided however that the overhang of the vehicles is limited.
  • This limitation admissible for radii of curvature of the order of 80 meters, becomes prohibitive for smaller radii of curvature, which can go down to 30 meters, as they occur frequently in metro networks.
  • the object of the present invention is to provide a device capable of being installed on a train composed of at least two vehicles with two axles, and allowing the adjacent axles of another vehicle to take a suitable orientation in relation to the track, even for very small radii of curvature thereof, limiting the transverse displacement of the axles relative to the axis of the wagon to a small value. It also aims to prevent the longitudinal traction forces exerted by an axle from being transmitted by one of the connecting rods to the body which it carries and by the other connecting rod to the adjacent body, by creating a torque of pivoting of vehicles.
  • the device according to the invention is characterized in that said first connecting rod connects the second articulation point to the first fixed anchoring point, in that said fourth connecting rod connects the third articulation point to the second fixed anchoring point, and in that it further comprises vertical levers suspended from third and fourth anchor points each disposed respectively opposite said first and second anchor points on the opposite end of the adjacent vehicle, and in that six connecting rods longitudinal connect said first, second, third and fourth points of articulation and the four aforementioned anchoring points so that on one side of the ten longitudinal axis of the vehicles a connecting rod connects the second point of articulation to said vertical lever suspended from said third anchor point, which is connected, on the one hand by a connecting rod to the fourth point of articulation, and on the other hand by the end of said lever and another connecting rod to the first point of anchoring, and that on the other side of said longitudinal axis of the vehicle there are three symmetrical connections from the previous connections.
  • the fixed point 31 attaches two longitudinal connecting rods 11 and 21; the connecting rod 11 is linked to the articulation point 51 of the axle 5 of the same box, the connecting rod 21 is linked to the articulation point 61 of the axle 6 of the adjacent box.
  • the fixed anchor point 32 attaches two longitudinal connecting rods 12 and 22, the connecting rod 22 is linked to the articulation point 62 of the axle 6 of the same body, the connecting rod 12 is linked to the articulation point 52 the axle of the adjacent body.
  • the axle 5 pivots around of the articulation point 51, linked to the body of the vehicle 1 by the connecting rod 11 and the fixed anchor point 31, likewise the axle 6 pivots around the articulation point 62, linked to the body of the vehicle 2 by the connecting rod 22 and the fixed anchor point 32. If the connecting rods 11, 12, 21, 22 are strictly parallel to the longitudinal axis, the axles 5 and 6 assume an orientation parallel to the external bisector of angle a; they remain parallel to each other, and their position relative to the track is not perfectly radial.
  • the distance "a” from the fixed anchor points under boxes 31 and 32 to the longitudinal axis of the vehicles is less than the distance "b" from the articulation points 51, 52, 61, 62 to which the longitudinal connecting rods hang on the axles 5 and 6 with respect to this same axis.
  • the optimal a / b ratio depends on the longitudinal dimensions of the vehicles but is always less than 1.
  • FIG. 4 represents a view in elevation and perspective of this variant, taken in the vertical plane of the fixed point 31 of the body 1.
  • This body 1 rests at its end adjacent to the body 2 on the axle 5 and the body 2 rests by its end adjacent to the body 1 on the axle 6.
  • Connecting rods 111 and 211 respectively connect the articulation point 51 of the axle 5 and the articulation point 61 of the axle 6 to a vertical lever 35 suspended at the anchor point 34 of the body 2, and the other end of which is linked by a longitudinal link 36 to the fixed anchor point 31 of the body 1.
  • the forces exerted by the axles 5 and 6 s '' apply half to the body 1 by the fixed anchor point 31 and the other half to the body 2 by the fixed anchor point 34.
  • a device symmetrical to that shown in FIG. 4 exists in the vertical plane of the fixed point 32 of the body 2. This variant makes it possible, as in the previous case, to provide the axles in the curves with the desired radial orientation.
  • each axle is oriented by the action of the body of the adjacent vehicle, which cannot be achieved for the end axles of the train.
  • the orientation of these axles could however be controlled by that of the nearest axle, by any known device, usually designated by the name of coupling between bogies.
  • the applications are in the field of railway, train or metro technology.
