Definitions

  • the present invention relates to a bogie comprising two beams between which extend at least two axles and, between them, a cross member, each end of which is joined to a respective one of the beams by an articulated connection.
  • Such bogies are used for traffic on poor track conditions. At least the very large inequalities are absorbed not by the play of a suspension between axle and spar, but by a pendulum movement of the spar in its vertical plane.
  • this type of chassis has the disadvantage of allowing numerous parasitic movements, and in particular the movements according to which each spar has a constant tendency to overtake the other or to be overtaken by it. In oscillatory mode, this type of movement leads to a winding trajectory of the entire vehicle, and possibly a derailment.
  • FR-A-22 01 999 concerns a joint without corner.
  • the cross member rests on the side members by means of elastic blocks having an arcuate shape or a V shape which tends to favor the configuration in which the two side members are perpendicular to the cross member.
  • the stability of the preferred configuration is very low, in particular because any deviation from this configuration certainly results in a overcompression of part of the elastic blocks, but also expansion of another part of the same elastic blocks.
  • FR-A-26 34 714 Also known from FR-A-26 34 714 is a bogie in which pre-stressed elastic blocks act in an oblique horizontal direction to apply a vertical face of the cross member, opposite these blocks, against a corresponding reference face of the side members, perpendicular to the longitudinal direction of the bogie.
  • This arrangement has the disadvantage of requiring that the reference faces take off from one another when the spar performs its pendulum movement in the vertical plane relative to the cross member.
  • the recall to the preferred configuration is independent of the load supported by the bogie, which is a drawback since the tendency of the bogie to take undesirable configurations increases with the loading supported by the bogie.
  • the object of the invention is thus to provide a bogie whose side members are articulated to the cross member with great freedom to carry out their pendulum movement in their vertical plane while being very effectively prevented from pivoting in the horizontal plane relative to said crosspiece.
  • the railway bogie comprising two beams between which extend at least two axles and, between them, a cross member each end of which is joined to one respective of the beams by an articulated link without corner which transmits to the side member the weight of the vehicle supported by the cross member while allowing the side member to travel in a plane perpendicular to the longitudinal direction of the cross member, is characterized in that: a lateral reference face belonging to the spar is in friction contact with a conjugate reference face belonging to the cross member, these lateral and conjugate reference faces being transverse to the longitudinal direction of the cross member; and the articulated connection is arranged so that the cross member transmits to the spar, under the action of said part of the weight of the vehicle a force having a horizontal component applying one against the other the lateral reference face and the conjugate reference face.
  • the force with a horizontal component can be obtained by pressing between bearing surfaces, at least one of which is oblique, preferably with the interposition of an elastic block.
  • the presence of the elastic block makes it possible to reduce the manufacturing tolerances of the cross member and the spar, and ensures a certain elastic return torque on the spar. If the elastic block is easily deformable in shear, it can be fixed to the spar and to the cross member. while allowing the side member to bear laterally against the reference faces of the cross member.
  • the chassis of the bogie comprises two side rails 1 whose general longitudinal direction M is, at rest, parallel to the rails 2 and to a median vertical plane PP of the bogie.
  • M general longitudinal direction
  • PP median vertical plane
  • the two longitudinal members 1 are supported by two axles 3 whose axis 4 is perpendicular to the plane PP.
  • the axles 3 are arranged symmetrically on either side of a median vertical transverse plane TT of the bogie.
  • each axle 3 carries two wheels 6.
  • the axles 3 have an axial extension 7 supported by a bearing 8 mounted in an axle box 9 located under the side member.
  • the base of each axle box 9 is extended forward and backward by an ear 11 extending in a substantially horizontal plane.
  • An elastic system 12, comprising in the example two helical springs with a common vertical axis, is supported in compression on the upper face of each lug 11.
  • one of the elastic systems 12 is supported directly under the spar 1.
  • the other elastic system 12 is supported in a cap 13 which is pulled down by the spar 1 via an oblique link 14. Due to the obliquity of the link 14, the cap 13 undergoes a force directed obliquely downwards, the component of which vertical compresses the elastic system 12 and the horizontal component of which is transmitted to the axle box 9 via a plunger 16 slidably mounted in the side member.
  • the pusher 16 is supported on a side face of the axle box 9 and pushes the axle box 9 to bear by its opposite side face against a corresponding wall 17 of the spar.
  • the longitudinal members 1 are joined to each other, in the TT plane, by a cross member 18.
  • the central region of the upper face of the cross member is shaped as a cylindrical crapaudine 19 for the articulation of the cross member 18 with the body (not shown) of the wagon.
  • the clamp 19 is intended to receive a complementary cylindrical pivot 21 fixed on the underside of the wagon body and connected axially to the cross-member, with the possibility of rotation around the central vertical axis of the bogie, by means of a retaining bolt 22.
  • the pivot 21 rests on the bottom of the clamp 19 by means of a sliding pad 23.
  • the cross member 18 still carries on its upper face, in the vicinity of the inner face of each spar, two lateral supports 37 for the wagon body.
  • These lateral supports are elastically compressible and have on their upper face a friction lining 38 intended to be in friction support. against the underside of the wagon body to support the wagon body at a distance from the toe plate 19 and therefore remove most of the tilting loads to which the base plate could be subjected, and at the same time dampen by friction any movements of bogie laces in relation to the wagon body.
  • Each end of the cross member 18 is engaged in a window 24 of one of the side members 1.
  • An elastic joint is produced between the cross member 18 and the side member 1 in this opening. This connection provides prepositioning of each beam 1 relative to the crosspiece 18.
  • each spar 1 carries on its inner face, that is to say facing the other spar 1, two friction linings 26 located on either side of the window 24, which define two reference faces side of the coplanar spar and parallel to the PP plane.
  • the crosspiece 18 carries in the vicinity of each of its ends and on each of its lateral faces a console 27 on which is fixed, facing one of the linings 26, a friction lining 28.
  • the friction linings 28 define on the cross-member 18 two reference faces which are combined with those defined by the linings 26 on the beam 1, and which are coplanar and perpendicular to the longitudinal direction L of the cross-member 18.
  • the corresponding spar 1 is in a configuration orthogonal to the cross member 18.
  • none of the two longitudinal members 1 is not ahead of the other with respect to the direction of advance of the bogie along the rails, provided that the distribution of the clearances X and X '(FIGS. 1 and 2) which are reserved on both sides and other of the crosspiece in the window 24 in the longitudinal direction M, the same at the two ends of the crosspiece.
  • each spar 1 can pivot in a pendulum movement around an axis parallel to the longitudinal direction L of the cross member 18 without this causing separation between the friction linings 26 and 28. Such a movement simply requires sliding with friction between these linings, which plays a beneficial role of damping.
  • each end of the cross member 18 bears by its base against the base of the window 24, by means of two elastic blocks 32 each comprising a mass of rubber or other elastomer 33 interposed between two end plates 34 and 36.
  • the base of the window comprises two faces 31 in the form of a concave dihedral symmetrical with respect to the transverse plane TT, and the base of the cross-member end has a complementary convex dihedral form, the two faces 29 of which, when the bogie is at rest, substantially parallel to the faces 31 of the cross-member.
  • the two elastic blocks 32 are each mounted between one of the faces 31 of the window 24 and the parallel face 29 of the cross-member.
  • Each elastic block 32 is relatively little compressible, but very flexible in shear deformation so that the block 32 transmits little force parallel to its bearing faces. Thus the pressing forces exerted by the block 32 on each of these faces are substantially perpendicular thereto.
  • Each face 31 and each face 29 is inclined at an angle A (FIG.
  • the angle A is oriented so that the pressing force F of the elastic block 32 (FIG. 3) on the corresponding face 31 of the window 24, has a horizontal component F HT parallel to the direction L which pushes the beam 1 towards the plane longitudinal median PP and therefore tends to press the side member by its two friction linings 26 against the two friction linings 28 integral with the cross member 18.
  • the face 31 is therefore directed obliquely upward and towards the plane PP.
  • the elastic block 32 exerts on the face 29 of the cross-member 18 a force having a component directed horizontally towards the outside of the bogie, but this force is balanced by an equal and opposite force exerted by the elastic blocks on which s supports the other end of the cross member 18.
  • transverse horizontal component F HT produced by each elastic block 32 on the associated spar 1 continuously tends to produce between the linings 26 and 28 the support by which the spar 1 retains its preferred configuration with respect to the cross member 18.
  • the two faces 31 and the two faces 29 form an angle B of approximately 30 ° with the longitudinal direction M of the spar 1.
  • this inclination has the consequence that the pressing force F exerted by each elastic block 32 on the corresponding face 31 of the window 24 has a horizontal component F HL parallel to the longitudinal direction M of the beam 1.
  • the two components F HL are equal and opposite: this is the position of stability.
  • a stop shoulder 39 is provided for each block 32 (FIG. 3) in the vicinity of the upper end of the face 29 and a stop shoulder 41 at the neighborhood of the lower end of each face 31.
  • the angle A (figure 3) is chosen equal to 25 ° and the angle B (figure 1) is chosen equal to 30 °.
  • the rubber of the blocks 32 can have a Shore hardness equal to 50.
  • the dimensions (length and width) of the rubber blocks 32 are chosen to be sufficient so that the blocks do not undergo excessive pressure from the cross member and the side members.
  • the spar Under the lateral thrusts transmitted to the spar by the axles, the spar tends in circulation to have parasitic movements which would correspond to detachment of the one of the pairs of linings 26, 28, the other pair of linings 26, 28, located on the other side of the cross member acting as a hinge.
  • this tendency to parasitic movement is combated by the elastic blocks loaded by the cross-member 18, and more particularly by the component F HT of their compression force F.
  • This force is proportional to the load supported by the cross-member 5, so that the stability increases with the load supported by the bogie, as is desirable, since the parasitic forces are themselves proportional to the load.
  • the elastic blocks 32 oppose only a small return torque against the pivoting movements of each beam 1 around an axis parallel to the longitudinal direction of the cross-member.
  • the bogie according to the invention allows the two longitudinal members to take different orientations around an axis parallel to the longitudinal direction of the cross-member, which makes it possible to distribute the load on the four wheels 6 of the bogie even when the railroad track is very distorted. All this is possible without the cross member 18 having to tilt relative to the wagon body. This is why the invention allows the use of a flat cylindrical plug, as explained above.
  • one of the sets X or X ′ may momentarily cancel each other out and a lateral face of the cross-member may come into contact with the lateral face of the window 24 situated opposite. This is without disadvantage, these two faces being dimensioned sufficiently wide to undergo such an impact without damage.
  • the invention is not limited to the example described and shown.
  • the cross-member could have, in place of the surfaces 29, a single surface in the form of a cylinder sector whose generatrices are parallel to the edge separating the surfaces 29. This cylindrical surface is directly supported, by two of its generators, on the surfaces 31 of the spar.
