Definitions
- the present invention relates to improvements bogies, in particular of the type intended to ensure the maintenance of freight wagons.
- the means of connection between the party bottom of the wagon and the top of the bogie consist of a toad which includes a surface in the shape of a semi-spherical bowl in which comes to bear an element of form complementary placed at the base of the wagon.
- Such means link allow to give link bogie / wagon with great deformation capacity.
- the present invention relates particularly the toad located in the upper part of the bogie.
- this toad 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, consists of an element reported whose base takes place in an orifice circular provided at the top of the bogie and which is fixed on it by a first weld bead circular made from inside the bogie.
- the external part of the clamp rests on the sheet upper part of the bogie by a circular shoulder, generally inclined to the vertical, the base is fixed by a second circular weld bead on the upper sheet of the bogie.
- the loading plan that is to say the contact area between the support element which is integral with the base of the wagon and the receiving element, or toad, which is integral with the internal face of the bogie, be as low as possible given of course templates imposed by legislation in matter.
- the object of the present invention is to provide a new type of toad, as well as ways to fixing the latter in the upper part of a bogie, allowing on the one hand to lower the loading plan of notable way and, on the other hand, to improve its solidarity with the bogie as well as resistance to the fatigue of the bond.
- the present invention thus relates to a bogie, especially for freight wagons, from type comprising a semi-spherical strainer intended for ensure an articulated link with resources complementary to the base of the wagon, characterized in that the upper periphery of the toad extends outward through a flat area, perpendicular to its axis of revolution, which comes fit into the upper plane of a bogie beam and which is fixed thereon by welding.
- the base of the toad can be secured with at least two substantially vertical opposite walls which extend downward so that they form a element of a box. These substantially vertical walls can be connected together by their ends of so as to constitute a box.
- the top of the basket is substantially confused with the upper plane of the beam.
- a bogie is made of two side rails which are joined on the one hand by a central cross member and on the other hand by two cross members minor extremes.
- the central crosspiece forms a sort of box beam 1 which unites transversely the two side members.
- Classically the toad 2 is arranged in the upper part of the central beam 1.
- the crapaudine 2 consists of a semi-spherical element with concavity turned upward and which comprises, at its base, a cylindrical boss 3 pierced in the center with a bore 5.
- the latter does not include 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 flat circular crown 9 which is an integral part of said element. This crown 9 takes place in a recess provided in the sheet upper 7 forming the upper wall of the beam central 1.
- the fixing of these two elements is ensured by a circular weld bead 10 which can be made from the upper side of the bogie and / or from its underside.
- the beams which ensure the support of the cranks have vertical and longitudinal partitions, (i.e. these partitions are perpendicular to the longitudinal axis xx 'of the beam) which connect the sheet upper 7 of this beam 1 to the lower sheet 12 as well as possibly to the side plates, so as to form a box element giving this area of beam better mechanical resistance.
- the method of fixing the clamp according to the present invention also makes it possible to constitute a box, but this box is made from a basic element which is the toad itself, which strengthens the maintenance and integration of this in the beam 1.
- partitions substantially vertical and longitudinal 14 are fixed by welding on shoulders 16 provided at the base of the basket 2 and extend downward to be fixed by welding on the sheet 12. These partitions 14 are also fixed by their ends on the vertical walls 17 of the beams 1 which forms a box. The toad 2 is located thus fully integrated into the structure of the beam transverse 1.
- the partitions 14 may be slightly inclined relative to the vertical so that as shown in Figure 1, their base is connected with the angle formed by the horizontal bottom plate 12 with an inclined lower sheet 12a.
- each wall element 14 is planned vertical partitions 14 which extend downwards to from the shoulders 16 provided at the base of the clip 2. These wall elements 14 are welded between them by their ends so that they constitute with the crapaudine a real box whose base will come attach to 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 basket 2 and its partitions vertical 14 can be made in one piece obtained for example by molding.
