Abstract

The present invention relates to a railway carriage body comprising, in the region of the top, two longitudinal members (20) connected by cross-members (40); in the region of the floor, two longitudinal members (10) connected, in the central part (A) of the body, by means of a floor (11); in the region of the flanks, on each side of the door apertures, a vertical member (30) connecting a top longitudinal member (20) and a floor longitudinal member (10), characterised in that each vertical member (30) consists of a profile of large cross-section, these profiles themselves alone forming the working structure in the region of the flanks.

Description

The present invention relates to a box of railway cars

  comprising, at the level of the roof, two longitudinal members connected by sleepers, at floor level, two connected longitudinal members, in the central part of the body, by a floor, at the flanks, on each side of the door openings, a stud linking ur

  roof spar and floor spar.

  Document EP-A-0 260 200 discloses such a box in which the faces consist of panels each composed of a honeycomb network surrounded by framing profiles. These frame profiles ensure, alone or with the amounts installed on each side of the door openings, the connection between the roof and floor rails However, whether or not there are door jambs, bees always participate in the working structure The openings in these panels, such as bay windows for example,

  must be limited on the surface.

  The present invention aims to increase this non-working surface, and this is achieved by a total suppression of the honeycomb panels, the working structure, at the flanks, being then only achieved by amounts of significant section The surface glass can then be total between two

door jambs.

  The box according to the present invention is characterized in that each amount consists of a profile of large section, these sections alone constituting the working structure at the flanks, the packing elements then being purely decorative. It is described below, with reference to the accompanying drawings,

  an embodiment of the car body according to the invention.

  Figure 1 shows the box in perspective.

  Figure 2 shows this box in cross section.

  Figure 3 shows two details of Figure 2, with a view to

enlarged.

  FIG. 4 shows an amount in section along IV of the

figure 2.

  In FIG. 1, the central part is referenced A and the end parts of the box are referenced B. The central part A, clearly visible in FIG. 2, comprises two longitudinal members 10 at the level of the floor, and two side members 20 at the level of the floor. A floor spar and a roof spar are interconnected by four vertical uprights 30 Both

  roof rails 20 are interconnected by cross members 40.

  The two floor rails are interconnected at each end of the central portion by transverse sections 11, a floor 12 being placed between these two transverse sections 11 and the two longitudinal members 10 This floor may be, for example,

made of aluminum panels.

  The ends B each consist of a platform located in the extension of the floor A platform comprises a knuckle 61 and, on each side, two bosses 62 allowing the establishment of a bogie Each end has two panels 63

  connected, at the flag level, by a crossbar 64.

  These two panels are separated by a gangway.

  The two roof rails 20 run all along the body and they bear on the uprights 30 and, at the end, on

the panels 63.

  The working structure of the body is constituted by the two floor rails 10, the two platforms 60, the two roof rails 20, the cross members 40 and 64, the eight vertical uprights 30 and finally the panels 63.

welded together.

  This box has only four uprights 30 per side, two on each side of a door opening. It is therefore possible to install three covering panels per side, one between the two door pillars of the central part and one in each part. The uprights 30 are set back from the outer edge of the longitudinal members 10, so that each trim panel extends in front of an upright and -3-

mask this one.

  Figure 2 shows two cladding panels 70 These cladding panels 70 may consist of, for example, a glass plate, because this plate does not participate in the working structure. Each trim panel 70 is installed between a box 50 integral with a floor spar 10, and a section 21 integral with a roof spar 20 A box 50 could consist of a single profile, but preferably a box 50 consists of two sections 51, 52 welded together, as shown in FIG.

figure 3.

  FIG. 2 shows that a shim 80 is positioned between an upright 30 and a casing 50. To modify the width of the crate, it suffices to vary only the shape of the non-working structure, in particular by modifying the thickness of the panel 50 and or

  the shape of the curve of the cladding panels.

  FIG. 4 shows a preferential embodiment of an upright 30 which is hollow, made of aluminum, and its inertia along the X axis is close to 3000 cm 4 and along the Y axis close to 6500 cm 4. amount can be realized in other forms and

in other subjects.

Claims (5)

claims   1 / Box of railway cars comprising, at the level of the roof, two longitudinal members (20) connected by sleepers (40), at floor level, two longitudinal members (10) connected, in the central part (A) of the body, by a floor (11) at the flanks, on each side of the door openings, an upright (30) connecting a roof spar (20) and a floor spar (10), characterized in that each upright (30) consists of a section of large section, these profiles constituting alone the working structure at the level flanks.   2 / Case according to claim 1, characterized in that it comprises, between the two uprights of the central portion (A) and at each end (B), a box (50) supporting a panel dressing (70).   3 / Case according to claim 2, characterized in that the box   (50) consists of two sections (51, 52) welded together.   4 / Case according to one of claims 2 and 3, characterized in that   it comprises, at the level of a roof spar (20), a profile   (21) ensuring the maintenance of a trim panel (70).   5 / Case according to one of claims 2 to 4, characterized in that   it comprises, between an amount (30) and a box (50), a hold (80).
