FR2635064A1 - Aluminium rail-vehicle body - Google Patents

Abstract

The present invention relates to an aluminium rail-vehicle body comprising, in the region of the floor, two resistant strong longitudinal elements 2, in the region of the roof two other resistant strong longitudinal elements 4, and in the region of the faces vertical metal columns framing the doors; the roof, floor, faces and ends consisting of panels 10, characterised in that at least one of these panels is formed from multi-tubular sections 11 joined on edge one after the other and welded to one another.

Description

Aluminum railway car body.

 The present invention relates to a body of aluminum railway cars.

 Document WO 86/00268 discloses a body of railway cars comprising, at the faces, vertical metal uprights, horizontal stiffeners welded to the uprights, and sheet metal spot welded to the uprights and stiffeners.

 Such a body therefore comprises a large number of stiffener and sheet metal amounts which must be assembled by welding, which means that a large number of these welds have to be made.

 The present invention makes it possible to considerably limit the number of welds by eliminating the stiffeners, the sheets and most of the vertical uprights, because in the box of the invention only the vertical uprights at the level of the doors are preserved, the face panels being formed profiles joined together in the field and welded together automatically.

 The present invention relates to a body of aluminum railway cars, comprising, at floor level two longitudinal resistant elements, at the level of the pavilion two other longitudinal resistant elements, at the faces of the vertical metal uprights framing the doors; the pavilion, the floor, the faces and the ends being made up of panels, characterized in that at least one of these panels is formed from multitubular profiles joined in the field one after the other and welded together.

 The face panels preferably consist of multitubular profiles arranged horizontally.

 The openings for the windows are obtained by machining the multitubular profiles in the mass.

 The end panels preferably consist of multitubular profiles arranged vertically.

 The roof and floor panels SOnw preferably made up of multi-tubular profiles arranged longitudinally.

 In some cases, to lighten the body without affecting its compressive strength, the roof and floor panels located at both ends of the car are formed from multi-tubular profiles, and the roof and floor panels located in the central part are formed of a honeycomb type network.

In the case of a two-storey box, the central part further comprises an intermediate floor separating the two floors, formed of a honeycomb type network, this floor being supported, at each face, on a intermediate resistant element.

 It is described below, by way of example and with reference to the accompanying drawings, a two-storey railway car body.

 Figure 1 shows a box seen from the front.

 FIG. 2 shows a half-section along line II of FIG. 7.

 FIG. 3 shows a half-section along line III of FIG. 7.

 Figure 4 shows a half-section along IV of Figure 1.

 FIG. 5 shows a half-section along V of FIG. 1.

 In FIG. 1, the body 10 of a double-decker railway car consists of a central compartment A with two floors and two ends B constituting the attachment and support areas of the axles, and the passage from one car to another.

 One face consists of two panels 10, each panel being obtained by superposition of profiles 11, this being clearly visible in the following figures.

 The face has a door 70 and glass windows 60.

 The door 70 comprises two vertical uprights 5, 6 made up of profiles.

 One end consists of panels 20.

 Figures 2 and 3 show, in section, the constitution of the body in its central compartment A. This body consists of four longitudinal resistant elements, two floor elements 1, 2 and two roof elements 3, 4. The body comprises two additional resistant elements 7, 8 carrying an intermediate floor 50 consisting of a panel 51 of the honeycomb type.

 The two front panels 10 are obtained by superposition of sections 11 on the field, and by welding these sections together continuously.

 Of course, for a single-story car, each side would consist of a single panel 10, connecting a resistant floor element and a resistant roof element.

 Figure 3 shows an opening in each panel 10, allowing the mounting of a window 60. This opening is obtained by direct machining in the mass of the panel, the window then being placed in this opening.

 FIGS. 2 and 3 show, in the central compartment A, a floor 40 and a roof 30 made up of panels, respectively 41 and 31, of the honeycomb type. The floor and the roof can, of course, be made up of multitubular profiles.

 Figures 4 and 5 show, in the ends B, a floor 45 consisting of multitubular sections 46 joined on the field and welded together, and a pavilion 35 formed of multitubular sections 36 joined on the field and welded together.

 Figure 4 shows a door opening, the amount 5 consisting of a profile attached to the adjacent face panel.
