Description

La présente invention concerne les châssis de bogies, en général, et porte, plus particulièrement, sur un châssis de bogies en alliage d'aluminium.The present invention relates to bogie frames, in general, and relates, more particularly, to a bogie frame made of aluminum alloy.

Comme indiqué dans l'article "L'ALLEGEMENT DES CHASSIS DE BOGIES MECANO-SOUDES DES TGV", publié dans la Revue générale des chemins de fer, Novembre 1993, pages 17 à 23, aux éditions GAUTIER-VILLARS, un bogie remplit un certain nombre de fonctions principales, grâce à des organes conçus et proportionnés pour cela.As indicated in the article "LIGHTENING CHASSIS OF MECANO-SOUDES TGV BOGIES", published in the General Review of Railways, November 1993, pages 17 to 23, published by GAUTIER-VILLARS, a bogie fulfills a certain number of main functions, thanks to organs designed and proportioned for this.

Ces fonctions sont, notamment:

  • la fonction guidage, fonction dans laquelle interviennent les roues et les essieux;
  • la fonction freinage, fonction dans laquelle interviennent les cylindres et les disques de frein;
  • la fonction traction, fonction dans laquelle interviennent les moto-réducteurs et les ponts sur essieux;
  • la fonction confort, fonction dans laquelle interviennent les suspensions primaires et secondaires.
These functions are, in particular:
  • the guidance function, a function in which the wheels and axles are involved;
  • the braking function, a function in which the cylinders and the brake discs are involved;
  • the traction function, a function in which the gearmotors and axle axles operate;
  • the comfort function, a function in which primary and secondary suspensions are involved.

L'art du concepteur de châssis est de réaliser des choix architecturaux qui aboutissent à un compromis convenable entre toutes les exigences auxquelles il est confronté, à savoir: tenue en fatigue, place disponible, masse, coûts de réalisation.The art of the chassis designer is to make architectural choices which lead to a suitable compromise between all the requirements which he is confronted with, namely: fatigue strength, available space, mass, production costs.

Les châssis de bogies de l'état de la technique sont principalement réalisés en construction mécano-soudée à partir de tôles d'acier du type A42 FP, selon la norme NF A 36-205.The state-of-the-art bogie frames are mainly made in mechanically welded construction from steel sheets of type A42 FP, according to standard NF A 36-205.

Ces tôles d'acier sont découpées, grenaillées, planées, pliées et préparées pour être assemblées entre elles, par soudage, pour former des sous-ensembles en forme de caissons qui, après l'opération finale d'assemblage, constituent le châssis définitif.These steel sheets are cut, shot blasted, planed, folded and prepared to be assembled together, by welding, to form sub-assemblies in the form of boxes which, after the final assembly operation, constitute the final chassis.

Outre un cycle de fabrication long, lié à l'assemblage d'un nombre élevé de tôles, à savoir: une centaine de pièces élémentaires, la réalisation du châssis nécessite une parfaite maîtrise de l'exécution et du contrôle des joints soudés.In addition to a long manufacturing cycle, linked to the assembly of a large number of sheets, namely: one hundred elementary parts, the production of the chassis requires a perfect mastery of the execution and control of welded joints.

Il ressort de cet article, ainsi que des réalisations des bogies de l'art antérieur, que les études pour la réalisation de châssis de bogies portent sur l'utilisation de l'acier essentiellement sous forme de tôles.It emerges from this article, as well as from embodiments of the bogies of the prior art, that the studies for the production of bogie frames relate to the use of steel essentially in the form of sheets.

Aussi est-ce le mérite de la demanderesse que de proposer un châssis de bogie faisant appel à des matériaux non encore utilisés dans les structure de châssis de bogie et allant à l'encontre de préjugés de l'homme du métier.It is therefore the merit of the applicant to propose a bogie chassis using materials not yet used in the bogie chassis structure and going against prejudices of the skilled person.
