The invention relates to a bar (10) for a braked aircraft wheel (103), the bar being for fitting to a rim (104) of the wheel in order to drive rotor brake disks (106b) in rotation. The bar comprises a substantially rectilinear body (11) having at least one segment (14) including two wings (15) connected together by a core (16) and intended to co-operate with the rotor disks. At least one brace element (17) connects a free edge of each of the wings to a central portion of the core.
