Composite brake disc for a vehicle disc brake

A composite brake disk for a vehicle disk brake, comprising:

• a brake disk pot formed from a first material, and
• a friction ring, which is formed from a different material and is connected to the brake disk pot,
• wherein the brake disk pot has a pot base extending in a radial direction with respect to an axis of rotation, and a circular-cylindrical pot shell extending from the pot base concentrically with respect to the axis of rotation, wherein the friction ring has at least two friction surfaces oriented in the radial direction with respect to the axis of rotation, and a circular-cylindrical collar pre-stretched axially in a direction of the brake disk pot concentrically with respect to the axis of rotation, and wherein the pot shell and the collar overlap in some regions in the radial direction in a connecting region and are penetrated by a plurality of connecting elements oriented substantially orthogonally with respect to the axis of rotation, wherein the collar engages radially on the outside around the pot shell in the connecting region.
