Definitions

  • the invention relates to a suspension and damping device for rail vehicles with steerable axles, of the type known, for example, from French patent 1,256,132, certificates of addition 77428 and 82179 attached to the aforementioned French patent as well as by French patents 2,477,090 and 2,490,172.
  • Suspension and damping devices of this type which can be used to orient the axles of a bogie with respect to the bogie chassis or the axles of an agon with respect to the chassis or body of the wagon, include, for each axle, two axle boxes on each of which the chassis to be suspended is supported by two helical compression springs arranged on either side of the box.
  • Each spring is capped with a cap and the connection between the frame and the two caps is ensured by two pairs of connecting elements articulated on the caps and on the frame so that the lines of action of the two pairs of connecting elements converge downwards.
  • the axle box has, in the longitudinal direction of the chassis, a freedom of movement limited by two guard plates integral with the chassis and two pushers guided in said guard plates are interposed between the caps and the axle box, these pushers rubbing on the two opposite sides of the axle box.
  • the pushers are guided in the guard plates integral with the chassis to be suspended so as to be movable along their axes, the axes of the pushers being orthogonal to the axis of the axle when the latter has not undergone orientation.
  • the axes of the lifters are no longer perpendicular to the axle of the axle and the conditions of friction of the lifters on the sides of the axle box are modified in proportions which are a function of the angle of orientation, this modification being able to go as far as jamming detrimental to the orientation of the axle.
  • This orientation of the axles does not have a very significant consequence on the friction function of the pushers in the case of bogie axles, owing to the fact that due to the small wheelbase of the bogie axles, this orientation can be limited in this case. at very low angular values.
  • the present invention relates to a suspension and damping device for rail vehicles with steerable axles, overcoming the drawbacks of known devices of this type, that is to say allowing the orientation of the axles without affecting the transverse stability of the vehicle.
  • the invention also relates to a suspension and damping device designed so that it can be used for axles other than bogie axles and in particular for vehicle axles with two axles only.
  • the device according to the invention for suspension and damping for rail vehicles with steerable axles comprises, for each axle, two axle boxes on each of which the chassis to be suspended (bogie chassis or wagon body) is supported by two helical compression springs arranged on either side of each box.
  • Each spring is capped with a cap and the connection between the frame and the two caps is ensured by two pairs of connecting elements articulated on the caps and on the frame so that the lines of action of the two pairs of connecting elements converge downwards.
  • the axle box has, in the longitudinal direction of the chassis, a freedom of movement limited by two guard plates integral with the chassis.
  • each plunger is an articulated plunger comprising a rod guided in the guard plate and a friction sole in contact with the axle box, the sole being articulated on the rod.
  • the friction conditions of the lifters on the axle box are not affected by the orientation of the axle, which allows without altering the lateral stability of the vehicle, relatively angles of orientation important of the axle, as necessary to enable correct registration in the curves of the axles of large wheelbase vehicles, for example of two - axle wagons.
  • each push rod has, at its end facing the axle box, a blind hole with a hemispherical bottom and the friction sole comprises, opposite its friction face, a projecting spherical head cooperating with the hemispherical bottom of the blind hole in the stem.
  • the spherical head projecting from the sole ⁇ e friction is connected to the latter by a neck of diameter smaller than the diameter of the head and is held in the blind hole of the rod by a retaining ring engaged in a qorqe of the boron hole.
  • Such an arrangement makes it possible to dissociate the two friction functions which occur, on such suspension devices, for the purpose of damping between the pushers and the axle box, namely horizontal friction for damping transverse movements ( transverse stability) and friction in the vertical direction for damping vertical movements (vertical stability).
  • transverse stability for damping transverse movements
  • vertical stability friction in the vertical direction for damping vertical movements
  • FIGS. 1a and 1b schematically show in elevation and in horizontal section the conditions of contact of non-articulated pushers with an axle box during the orientation of the axle
  • FIGS. 2a and 2b represent same manner of contact conditions when using articulated pushers
  • Figure 3 shows, in detail, the vertical section of a suspension and damping device according to 1 * i nvention
  • Figure 4 shows larger scale the structure of an articulated pusher.
  • an axle box 2 in which is mounted an axle 3 with wheels 4 has horizontally, in the longitudinal direction of the chassis 1, mobility limited by two guard plates 5 integral with the chassis 1 and framing the axle box 2 with play on the two opposite sides.
  • the chassis 1 is supported on the axle box 2 by means of two helical compression springs 6, the lower ends of which bear on lateral ears 7 of the axle box 2.
  • the springs 6 are capped, each at its upper end, by a cap 7 on which is articulated, by a horizontal axis 8, the upper end of a pair of connecting elements 9 whose lower end is articulated by a horizontal axis 10 on lateral legs 11 of the corresponding guard plate 5.
  • a pusher 12 guided in each of the guard plates 5 is interposed between each cap 7 and one side of the axle box 2, the pusher 12 comprising a rod 13 guided in the guard plate 5 so as to be able to slide in the direction longitudinal of the chasi 1, the rod 13 carrying by its free end against the cap 7 and having at its other end a friction sole 14 in contact with a friction lining 15 attached to the axle box 2.
  • Figures 2a and 2b show a suspension and damping device having the same general structure as that of Figures la and 1b, but using instead of rigid pushers 12 of Figures la and lb, pushers articulated 16 between the caps 7 covering the springs 6 and the axle box 2.
  • Each articulated pusher 16 which will be described in more detail below, with the aid of FIGS. 3 and 4, comprises a rod 17 slidingly mounted in the longitudinal direction of the chassis 1 in the guard plate 5, and a friction sole 18 in contact with one side of the axle box 2, the rod 17 being connected to the sole 18 by a hinge 19.
  • the articulation 19 of the pushers 16 allows the friction soles 18 to maintain, whatever the orientation of the axle 3, always the same friction conditions with the friction linings 15 provided on the axle box 2.
  • the rod 17 has, at its end facing the sole 18, a blind hole 20 with a hemispherical bottom 21.
  • the friction sole 18 carries, projecting from its face turned towards the rod 17, a spherical head 22 which, in the example shown, corresponds to a spherical segment at a base, of a height slightly greater than the radius of the sphere.
  • the head 22 is connected to the sole 18 by a neck 23 with a diameter less than the diameter of the head 22.
  • the head 22 is held in the blind hole 20 by a retaining ring 24 engaged in a groove in the blind hole 20, so that the head 22, in contact with the hemispherical bottom 21 of the blind hole 20, has sufficient freedom to allow the orientation of the sole 18 by relative to the rod 17 within the necessary limits taking into account the possibilities of orientation of the axle 3 between the guard plates 5.
  • FIG. 3 which is a detailed section of an embodiment of the suspension device according to the invention, it can be seen that the sole 18 of each pusher 16 is embedded and movable horizontally in a groove 25 of a slide 26, itself movable vertically in a groove 27 of a slide 28 fixed laterally on the axle box 2.
  • This makes it possible to dissociate the friction in the horizontal direction which determines the transverse damping, that is to say the transverse stability of the vehicle , vertical friction which determines the damping of vertical movements.
  • suspension springs 6 are supplemented, in a manner known per se, by additional suspension springs 29 arranged inside the main springs 6.
  • additional suspension springs 29 arranged inside the main springs 6.
  • the use according to the invention of pushers articulated 16 between the caps 7 of the suspension springs 6 and the axle box 2, is particularly advantageous in the case of individual axles, that is to say on vehicles which are not with bogie and whose axles have a large wheelbase.
  • the invention is also applicable to bogie axles, in particular on vehicles having to operate on tracks having curves of small radius.
