Definitions
- the present invention relates to a side wall for a rail vehicle body comprising a metal support frame and a metal outer covering welded to the frame.
- the invention applies in particular to the bodies of railway vehicles made of steel.
- resistive spot welding causes the marking of the outer face of the covering sheets, at the contact points between these sheets and the welding electrodes.
- this type of welding is prohibited by certain countries and / or certain companies.
- the object of the invention is to solve these problems by providing a side wall for a rail vehicle making it possible to respond economically to the visual appearance constraints mentioned above.
- the invention relates to a side wall for a rail vehicle body comprising a metal support frame and a metal outer covering welded to the frame, characterized in that at least some welds connecting the covering to the frame are laser welds made in overlapping zones between the frame and the tying, in that these welds are obtained by transparency from the inner face of the side wall, through elements of the support frame, and in that these welds are non-opening welds in the outer face of the side wall.
- the side wall may include one or more of the following characteristics, taken individually or in combination: - it includes a flag leaf intended to be connected to the flag of a rail vehicle body, and elements of the support frame are connected to the roof wing by laser welds produced in overlapping zones between these elements and the roof wing, these welds are obtained by transparency from the inner face of the side wall, at the through elements of the frame, and these welds are non-through in the outer face of the side wall; and - these laser welds are structural welds for force transmission.
- the invention also relates to a rail vehicle body, characterized in that it comprises two side walls as defined above.
- FIG. 1 is a cross-section and schematic of a box rail vehicle according to the invention
- FIG. 2 is a partial schematic view in external perspective of a side wall of the box of Figure 1;
- FIG. 3 is a partial, schematic view, partially broken away and inside perspective of the wall of Figure 2;
- Figures 4 and 5 are partial schematic sections taken respectively along lines IV-IV and VV of Figure 3.
- Figure 1 shows schematically a body 1 of a railway vehicle made of steel and which essentially comprises a chassis 2, a roof or pavilion 3 and two side walls 4 each of concavity directed towards the inside of the body 1.
- the walls 4 being symmetrical to each other with respect to a median longitudinal plane of the body 1, only one will be described below.
- the wall 4 essentially comprises a longitudinal lower spar 6 (at the bottom in FIGS. 1 and 3), a support frame 8, an upper arched part of the covering or flying the roof 10 and a outer covering 12, which extends between the side member 6 and the wing 10 and whose outer face 13 is smooth.
- the longitudinal member 6 connects the chassis 2 to the wall 4.
- the roof leaf 10 connects the roof 3 to the side wall 4.
- the steel frame 8 essentially comprises uprights 14 and longitudinal or long profiles 16 orthogonal to the uprights 14.
- the uprights 14 are very thick U-shaped profiles (FIG. 4) (3 to 5 mm), the lower ends of which (at the bottom in FIG. 3) are fixed, for example by MIG (Metal Inert Gas) welding, to the spar. 6 and whose upper ends are welded to the wing 10, as described later. These uprights 14 are arranged regularly along the side wall 4 and substantially orthogonally to the spar 6.
- the long ⁇ nes 16 are very thick profiles (3 to 5 mm) and of current section in ⁇ (figure
- the elements 14 and 16 of the framework 8 are assembled together, for example by MIG welding, at their meeting areas by forming assembly nodes. These elements 10 and 12 are furthermore stamped and cut at the level of these assembly nodes to present flat surfaces for fitting the covering 12.
- the outer covering 12 comprises, for example, thin steel sheets assembled together by edge-to-edge welding.
- the thickness of these sheets is typically less than 3 mm.
- the covering 12 is precut to provide openings 19 for windows.
- the covering 12 is arranged on the outside of the framework 8 and it is fixed to the uprights 14 by laser welding cords 20. As illustrated in FIG. 4, these laser welding cords 20 are produced in areas of overlap 21 between the covering 12 and the flat central cores 22 of the uprights 14.
- These weld beads 20 are obtained by transparency from the inner face 24 of the side wall 4 (below in FIG. 4). In other words, a laser beam has come through the core 22 of the upright 14 and then locally melt the covering 12 and thus weld the upright 14 and the covering 12 at their facing surfaces in the area of overlap 21. Thus, each weld bead 20 completely crosses the corresponding core 22 and then partially the covering 12 overlapping the core 22.
- weld beads 20 are non-opening in the outer face 13 of the covering 12.
- the covering 12 is fixed to the long ⁇ nes 16 by laser welding beads 26 produced in overlapping zones 27 between the lateral tabs 28 of the long ⁇ nes 16 and the covering 12.
- the tabs 28 have been enlarged on the Figure 3 for clarity.
- These weld beads 26 are produced by transparency from the internal face 24 of the wall 4 (on the right in FIG. 5) and are non-opening in the external face 13 of the covering 12.
- the uprights 14 are welded to the wing 10 in overlapping zones 30 between the latter and the uprights 14, by extension of the weld beads 20.
- the covering 12 is welded along its lower part to the beam 6, for example by MIG welding. This welding, carried out after welding of the covering 12 on the framework 8, induces limited deformations due to the rigidity imparted to the covering 12 by the framework 8.
- the weld beads 20 and 26, connecting the covering 12 to the framework 8, are structuring welds of force transmission.
- the covering 12 participates, with the framework 8, in the rigid fication of the side wall 4 and therefore of the body 1.
- the type of welding chosen makes it possible to limit the deformations induced in the covering 12 when it is welded to the frame 8.
- the operations necessary to restore a satisfactory visual appearance are limited; the non-opening weld beads 20 and 26 do not mark the outer face 13 of the wall 4, which makes it possible to obtain the desired visual appearance.
- the structure chosen side wall 4 allows automated assembly of these walls in relatively short times, laser welding to achieve welding speeds of 20 m / min.
- the weld beads 20 and 26 can be discontinuous and the use of laser welding can be limited to the areas necessary to ensure a satisfactory visual appearance.
