A brake disk includes at least one friction ring, which includes a base member. The brake disk also includes at least one hole and/or groove located in the friction ring. The brake disk also includes at least one coating, which is applied to at least portions of the friction ring. The coating comprises at least portions of the transition between the hole and/or groove and the friction ring. At least portions of the transition between the hole and/or groove and the friction ring are constructed to be rounded and/or chamfered in a flat manner.

Brake disk and method for producing a brake disk

A brake disc having a friction ring and a hub produced as a separate element and arranged inside the friction ring according. Recesses are configured in the friction ring on the inside to connect the hub to the friction ring and corresponding projections are formed on the hub, which projections engage in the recesses of the friction ring in order to be able to transfer torque from the friction ring to the hub. The recesses have an undercut at least partially in a radial direction, as viewed looking inward from the outside. The disc is simple and cost-effective to manufacture and has an acoustically advantageous operating performance, in particular in the case of thermal expansion.
