A brake disc for a vehicle disc brake has a friction ring supported by a brake disc chamber made of a specifically light material and having a central flat hub section perpendicular to the axis of rotation of the brake disc and a support wall section connected thereto. The support wall section extends radially outward and in some regions has a truncated circular cone shape, with whose free edge region the friction ring is connected via connection elements. The ratio of the height of the friction ring to the diameter of the brake disc is less than 0.12, and the connection between the brake disc chamber and the friction ring is provided with a prestressed support wall section such that the edge region of the brake disc chamber acts in an outwardly pressing manner upon the unheated friction ring directly or indirectly by way of the connection elements. |
