Definitions
- the present invention relates to improvements to bogies, in particular of the type intended to ensure the maintenance of freight wagons.
- the connecting means between the lower part of the wagon and the upper part of the bogie consist of a crapaudine which comprises a receiving surface in the form of a semi-spherical bowl in which comes to bear an element of complementary shape arranged at the base of the car.
- Such connecting means make it possible to give the bogie / wagon connection a large capacity for deformation.
- the present invention particularly relates to the toad located in the upper part of the bogie.
- this clamp especially when the bogie is made up of elements produced by the technique known as mechanically welded, that is to say in sheet metal elements which are assembled by welding, is made up of an insert whose base takes place in a circular orifice provided at the upper part of the bogie and which is fixed thereon by a first circular weld bead produced from inside the bogie.
- the external part of the clamp rests on the upper sheet of the bogie by a circular shoulder, generally inclined with respect to the vertical, the base of which is fixed by a second circular weld bead on the upper sheet of the bogie.
- the loading plane that is to say the contact zone between the support element which is integral with the base of the wagon and the receiving element, or crapaudine, which is integral with the internal face of the bogie, is arranged as low as possible, of course taking into account the sizes imposed by the legislation on the subject.
- the object of the present invention is to propose a new type of clip, as well as means for fixing the latter to the upper part of a bogie, making it possible on the one hand to lower the loading plane significantly and, d on the other hand, to improve its connection with the bogie as well as the fatigue resistance of the connection.
- the present invention thus relates to a bogie, in particular for goods transport wagons, of the type comprising a semi-spherical plate intended to ensure an articulated connection with complementary means integral with the base of the wagon, characterized in that the upper periphery of the toad extends outwards by a flat zone, perpendicular to its axis of revolution, which comes to be embedded in the upper plane of a beam of the bogie and which is fixed thereto by welding.
- the toad can have at least two substantially vertical opposite walls which extend towards the low from its base, so that it forms an element of a box.
- the substantially vertical walls of the basket can be connected to each other by their ends so as to constitute a box.
- the upper part of the basket is substantially coincident with the upper plane of the beam.
- Figure 1 is a partial vertical sectional view of a transverse bogie beam equipped with a clamp according to the invention.
- FIG. 2 is a partial top view of the beam and of the clamp shown in FIG. 1.
- Figure 3 is a partial top view of a transverse beam of a bogie equipped with an embodiment of a clamp according to the invention.
- Figure 4 is a perspective view and partial section of an alternative embodiment of a clamp according to the invention.
- a bogie is made up of two lateral beams which are joined on the one hand by a central cross member and on the other hand by two extreme cross members of lesser importance.
- the central cross-member forms a sort of box beam 1 which joins the two longitudinal members transversely.
- the toad 2 is arranged in the upper part of the central beam 1.
- the clamp 2 consists of a semi-spherical element with an upwardly-facing concavity and which comprises, at its base, a cylindrical boss 3 pierced in its center with a bore 5.
- the latter does not have a circular upper shoulder coming to bear on the upper sheet 7 of the central beam 1 of the bogie.
- the semi-spherical element ends at its upper part by a planar circular crown 9 which is an integral part of said element.
- This ring 9 takes place in a recess provided in the upper sheet 7 forming the upper wall of the central beam 1.
- the fixing of these two elements is ensured by a circular weld bead 10 which can be produced from the upper face of the bogie and / or from its underside.
- the beams which ensure the retention of the frills have vertical and longitudinal partitions, (that is to say that these partitions are perpendicular to the longitudinal axis xx 'of the beam ) which connect the upper sheet 7 of this beam 1 to the lower sheet 12 as well as possibly to the side sheets, so as to form a box element giving this beam area better mechanical strength.
- the method of fixing the clamp according to the present invention also makes it possible to constitute a box, but this box is produced from a basic element which is the basket itself, which reinforces the maintenance and the integration of this one in the beam 1.
- substantially vertical and longitudinal partitions 14 are fixed by welding to shoulders 16 provided at the base of the clamp 2 and extend downward to be fixed by welding to the sheet 12. These partitions 14 are also fixed by their ends to the vertical walls 17 of the beams 1 which form a box. The clamp 2 is thus completely integrated into the structure of the transverse beam 1.
- the partitions 14 may be slightly inclined relative to the vertical so that, as shown in FIG. 1, their base comes to connect with the angle formed by the horizontal lower sheet 12 with a lower inclined sheet 12a.
- FIG. 3 In another embodiment, shown on a smaller scale in FIG. 3, four vertical partitions 14 are provided which extend downwards from the shoulders 16 provided at the base of the basket 2. These elements wall 14 are welded to each other by their ends so that they constitute with the crapaudine a real box whose base will be fixed on the lower sheet 12 forming the base of the central beam 1. Furthermore the external shape of the flat area 9 'is no longer circular but has the shape of a square.
- the clamp 2 and its vertical partitions 14 can be made in one piece obtained for example by molding.
- the clamp 2 according to the invention makes it possible both to lower the loading plane of the bogie while improving the mechanical resistance of this part of it, in particular as regards the resistance to fatigue.
