BRAKE DISC COMPRISING A FRICTION RING AND A HUB PRODUCED AS A SEPARATE ELEMENT AND ARRANGED INSIDE OF THE FRICTION RING

摘要

A brake disc (10) comprises a friction ring (12) and a hub (22) produced as a separate element and arranged inside of the friction ring (12), wherein recesses (20) are configured in the friction ring (12) on the inside to connect the hub (22) to the friction ring (12) and corresponding projections (32) are configured on the hub (22), which projections engage in the recesses (20) of the friction ring (12) in order to be able to transfer torques from the friction ring (12) to the hub. To this end, the recesses (20) have an undercut at least partially in a radial direction, as viewed looking inwards from the outside.
