The invention relates to a brake disk having a face-end friction ring portion on which a brake disk cam provided with a cam bore is molded. In order to further develop the brake disk in such a manner that adequate safeties with respect to the permissible material values on brake disks for high-energy application cases are provided and material stresses in the region of the brake disk cam of the brake disk, which are caused through temperature differentials within the brake disk as a consequence of high braking energy inputs, are reduced, the brake disk cam includes two arm parts which extend spaced from each other from the face-end friction ring portion in the direction of the cam bore and converge in front of the cam bore.
A brake disk having a face-end friction ring portion on which a brake disk cam provided with a circular cam bore is moulded, wherein the brake disk cam is configured to connect the brake disk to a hub, characterised in that the brake disk cam comprises two arm parts which extend spaced from each other from the face-end friction ring portion in the direction of the circular cam bore and converge in front of the circular cam bore and behind the circular cam bore, and in that the arm parts each comprise a web which are moulded on the face-end friction ring portion and which are followed by arms which are substantially arranged parallel and spaced from the face-end friction ring portion.
