Abstract[English]
The invention relates to a torsion crossmember (6) for an axle (1), the torsion crossmember comprising a metal strip that has two longitudinal edges (10, 11) and is folded back on itself about a longitudinal axis, wherein the two longitudinal edges (10, 11) are welded to one another so as to form a closed section; the torsion crossmember (6) comprising at least one central region (Zc) and two end regions (Ze1, Ze2) which are respectively located at two opposite ends of the torsion crossmember (6); the metal strip having a thickness eext. in the end regions (Ze1, Ze2) and a thickness ecent. in the central region (Zc); the thickness eext. being greater than the thickness ecent.[French]
L'invention concerne une Traverse de torsion (6) pour un essieu (1) comportant une bande métallique qui présente deux bords longitudinaux (10, 11) et est repliée sur elle-même autour d'un axe longitudinal, les deux bords longitudinaux (10, 11) étant soudés l'un à l'autre de sorte à former une section fermée; ladite traverse de torsion (6) comportant au moins une zone centrale (Zc) et deux zones extrêmes (Ze1, Ze2) qui sont respectivement situées à deux extrémités opposées de la traverse de torsion (6); la bande métallique présentant une épaisseur eext. dans les zones extrêmes (Ze1, Ze2) et une épaisseur ecent. dans la zone centrale (Zc); l'épaisseur eext. étant supérieure à l'épaisseur ecent.
