Brake disk for disk brake, has friction ring for frictional engagement of brake disk with brake pad, while support cup is arranged coaxially with friction ring for supporting brake disk on hub, and teeth are formed on friction ring

摘要

The brake disk (10) has a friction ring (11) for frictional engagement of the brake disk with a brake pad, while a support cup is arranged coaxially with the friction ring for supporting the brake disk on a hub. The teeth (12) are formed on the friction ring and the counter teeth are formed on the support cup for the form-locking connection of the friction ring with the support cup. A groove (13) molded in the friction ring for insulating the heat of the brake disk. The friction ring is made from cast iron, particularly from a gray cast iron, where the groove is formed in the friction ring.
