Definitions

  • the present invention relates to a rail vehicle body structure.
  • the floors of the structure can be made of aluminum, while other parts such as the floor support rails are made of steel.
  • the various elements which compose it by welding it is preferable to join together the various elements which compose it by welding.
  • the welding of steel elements with aluminum elements requires special precautions, insofar as these materials are difficult to weld together and tend to generate galvanic corrosion when they are brought into contact.
  • the object of the invention is in particular to remedy the aforementioned drawbacks of the prior art by proposing a new body structure, the manufacture of which is more easy and less expensive, this new body structure not being less solid and durable than the known structures.
  • the invention also proposes a method of manufacturing such a structure, simple to implement (without chips or restrictive tolerance), economical, allowing direct assembly, and allowing to obtain a final structure having a high mechanical resistance.
  • the invention particularly relates to a body structure according to claim 1.
  • the structure is therefore produced on the one hand by inserting the slat into the notch, then by blocking the slat with respect to the notch thanks to the pin, passing through the panel and welded to the slat.
  • This assembly is simple and economical to produce, and has satisfactory mechanical strength.
  • FIG. 1 One represented on the figure 1 a body structure 1 of a railway vehicle, of the wagon, car or locomotive type.
  • the term "body” designates the upper part of the vehicle, resting on the bogies of the vehicle.
  • the crate is intended to contain people or goods transported by the vehicle or a traction assembly in the case of a locomotive.
  • the body comprises at least one horizontal panel 2 forming a floor, and side walls 4, only one of which is partially visible on the figure 1 , which rise from the floor 2 to define an interior volume V of the body.
  • several floors can be provided in order to form levels within the crate.
  • the body preferably comprises a roof or a roof, not shown, closing the volume V from above, and interior and exterior trim elements, also not shown.
  • the structure 1 also comprises a frame 6, formed mainly by an assembly of support elements, of the beam and upright type.
  • the support elements are made at least predominantly, or even completely, of steel or a steel alloy, to give the frame 6 a predetermined mechanical strength as a function of the conditions of use of the vehicle.
  • predominantly is meant that more than 50% by weight of each support element is made of steel or a steel alloy.
  • at least the majority of the support elements form metal profiles.
  • the support members are assembled with each other by welding, riveting, bolting, or any other suitable technique.
  • the frame 6 therefore constitutes a rigid framework, the main purpose of which is to support the equipment elements, including the floor 2 and the side walls 4.
  • Two longitudinal rows of vertical uprights support the side walls 4 of the body.
  • the frame 6 also includes at least two support elements 8, also called stretchers, only one of which is visible on the figure 1 , each forming a longitudinal beam of the frame 6.
  • Each of the support elements 8 connects the vertical uprights of one of the longitudinal rows to each other, being welded to these vertical uprights.
  • Each support element 8 is made of steel, or of a steel alloy, at least predominantly, and preferably completely.
  • Each support element 8 is preferably formed by a profile, that is to say a part obtained by extrusion of material, or is formed by an assembly of profiles fixed together.
  • the support elements 8 are arranged at the same height, between the two rows of vertical uprights and support the floor panel 2 of the structure 1.
  • each support element 8 has a flat fixing surface 9 and oriented along a longitudinal plane parallel to the walls 4.
  • Each fixing surface 9 is turned towards the inside of the body, so that the two fixing surfaces 9 face each other.
  • Each support element 8 also comprises a part shaped to receive a lower end of the vertical uprights, opposite the fixing surface 9.
  • the panel 2 for its part comprises a profile at least predominantly, or even totally, of aluminum or of an aluminum alloy, so that it is particularly easy to manufacture and comprises a reduced number of parts.
  • predominantly is meant that more than 90% by weight of the panel 2 is made of aluminum or an aluminum alloy.
  • the panel 2 comprises for example a first horizontal upper plate and a second lower plate, disposed away from, and parallel to, the first plate.
  • the panel 2 is delimited laterally by two longitudinal edges 18, only one of which is visible on the figure 1 , facing the mounting surface 9.
  • Panel 2 shown in more detail on figure 2 , has a first surface 15A delimited by the edge 18, and a second surface 15B parallel to the first surface 15A and opposite to this first surface 15A.
  • the panel 2 comprises at least a first notch 16A, formed on said edge 18, and extending parallel to the first surface 15A, close to this first surface 15A.
  • the panel 2 also includes a second notch 16B, parallel to the first notch 16A, and extending close to the second surface 15B.
  • the body structure 1 comprises means 34 for fixing the support element 8 with the panel 2.
  • the fixing means 34 comprise at least a first slat 14A of steel alloy, integral with the support element 8, inserted in said first notch 16A.
  • the fixing means 34 also comprise at least one second slat 14B parallel to the first slat 14A, also made of steel alloy, integral with the support element 8, and inserted in said second notch 16B.
  • each slat 14A, 14B has a longitudinal outer edge S 'through which this slat 14A, 14B is welded to the support member 8.
  • each slat 14A, 14B is integral with the support element 8, and belongs to this support element 8.
  • the fixing means 34 also comprise, for the first notch 16A, respectively second notch 16B, a first pin 24A, respectively second pin 24B, extending between a head 26A, 26B and one end 28A, 28B.
  • the first pin 24A extends through the panel 2 in a direction perpendicular to the first surface 15A, up to an interface 30A between the first notch 16A and the first slat 14A.
  • the head 26A rests on the first surface 15A, and the end 28A is friction welded with the first slat 14A.
  • the panel 2 is partly interposed between the head 26A of the first pin 24A and the weld between the end 28A of the first pin 24A and the first batten 14A.
  • the second pin 24B extends through the panel 2 in a direction perpendicular to the second surface 15B, up to an interface between the second notch 16B and the second slat 14B.
  • Head 26B rests on second surface 15B, and end 28B is friction welded with second batten 14B.
  • the panel 2 is partly interposed between the head 26B of the second pin 24B and the weld between the end 28B of the second pin 24B and the second batten 14A.
  • the panel 2 and the support element 8 are blocked with respect to each other by the pins 24A, 24B and by the cooperation of the slats 14A, 14B in the notches 16A, 16B.
  • the manufacturing process comprises a step of supplying the panel 2 provided with the notches 16A, 16B, and a step of supplying the support element 8 provided with the slats 14A, 14B.
  • the method then comprises inserting each slat 14A, 14B into the corresponding notch 16A, 16B.
  • the method then comprises the positioning of the first pin 24A, against the first surface 15A, in line with the first notch 16A in a direction perpendicular to the first surface 15A.
  • the method then comprises the rotation of said first pin 24A, and the penetration of the first pin 24A in the panel 2, through the first surface 15A, so as to form a passage orifice 29A extending from the first surface 15A up to the interface 30A between the first notch 16A and the first slat 14A.
  • the method finally comprises friction welding between the end 28A of the first pin 24A and first slat 14A, at the interface 30A between the first notch 16A and this the first slat 14A.
  • the panel 2 is partly interposed between the head 26A of the first pin 24A, resting on said outline of the passage opening 29A, and the end 28A of the first pin 24A, welded to the first batten 14A.
