Abstract
A brake disk with a friction ring or to a friction ring, which comprises a PMMC (particle metal matrix composite), at least in the region of its friction surface. The friction surface of the friction ring is provided with mechanically applied microgrooves, which extend in a radial direction with respect to a circumferential direction of rotation of the friction ring, non-tangentially angled thereto.
Claims14
A friction ring for a brake disk comprising:
- at least one friction surface configured for interacting with a brake lining, wherein the friction ring comprises an Al-MMC in one of at least in the region of the friction surface and the friction ring consisting completely thereof;
- the at least one friction surface has a plurality of microgrooves which extend in a radially directed manner with respect to a circumferential direction of rotation of the friction ring and non-tangentially angled thereto;
- and
- wherein the microgrooves are arranged orthogonally to the circumferential direction of rotation.
A method for machining the friction surface of a friction ring, the friction ring having at least one friction surface configured for interacting with a brake lining, wherein the friction ring comprises an Al-MMC material in at least one of in the region of the friction surface and the friction ring consisting completely thereof and comprising:
- moving the friction ring by a defined feed in the circumferential direction of rotation;
- and
- machining the friction surface with a tool rotating in a direction of tool rotation, wherein a plurality of microgrooves that extend radially with respect to the circumferential direction of rotation of the friction ring and non-tangentially angled thereto are thereby introduced into the friction surface, wherein the microgrooves are arranged orthogonally to the circumferential direction of rotation.
