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.
Claims11
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 a PMMC material (particle metal matrix composite) in the region of the friction surface;
- and
- the at least one friction surface has at least one microgroove which extends in a radially directed manner with respect to a circumferential direction of rotation of the friction ring, non-tangentially angled to the circumferential direction of rotation at least with one component.
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 a PMMC material (particle metal matrix composite) in the region of the friction surface, the at least one friction surface has at least one microgroove which extends in a radially directed manner with respect to a circumferential direction of rotation of the friction ring, non-tangentially angled to the circumferential direction of rotation at least with one component;
- and
- wherein the friction ring is offset with a defined feed in the circumferential direction of rotation and the friction surface is machined by a tool rotating in a direction of tool rotation, which the microgrooves are introduced into the friction surface.
