摘要

The brake disk (10) has a brake disk chamber (11) made from metal, a friction ring (12) made from fiber-reinforced ceramic, and connecting elements (18). Each connecting element has a guide portion (20) which is guided in an assigned radial groove (21) with a rear section (22) in a radial movable manner. A positioning portion (23) extends in a positioning opening (24) which runs transversally to the radial groove. the brake disk chamber is made from a light metal alloy and the friction ring is made from a carbon-silicon carbide-ceramic.
