Brake drum for a vehicle brake, comprising a main portion (2) with a cylindrical inner frictional surface (5), a radial flange portion (4), on which the wheel rim is intended to be bolted, and a transitional portion (3) between the main portion and the flange portion. The thickness of the transitional portion is successively reduced from the main portion towards the flange portion in order be weak enough to be able to absorb deformation caused by a non-planar rim and prevent the deformation from being transferred to the main portion. <IMAGE> |
