Abstract:
1. A brake disc for a vehicle disc brake, comprising: a friction ring; a brake disc chamber configured to support the friction ring, the brake disc chamber being made of a specifically light material and having a central flat hub section perpendicular to an axis of rotation of the brake disc and a support wall section connected to the central flat hub section and extending radially outward, the support wall section having, at least in some regions, a truncated circular cone shape; wherein the friction ring is connected via connection elements to a free edge region of the support wall section, the friction ring being made of a different material than that of the brake disc chamber; wherein a ratio of a height of the friction ring measured in a radial direction to a diameter of the brake disc is less than 0.12, and a connection between the brake disc chamber and the friction ring is produced with a prestressing of the support wall section such that the free edge region of the brake disc chamber acts in an outwardly pressing manner in the radial direction on the friction ring directly or indirectly via the connection elements when the friction ring is not in a heated condition due to braking operation; and wherein, viewed in the radial direction, the free edge region of the support wall section of the brake disc chamber has a slightly elastic construction, the slightly elastic construction being formed by finger-type segments of the free edge region configured to have an approximate S-type shape viewed in the radial direction.
