Brake disk for a motor vehicle's disk brake has friction rings linked to a pot-shaped retaining part and a ring extending proportionally over the cylindrical surface of the pot-shaped retaining part

摘要

Fastened on a brake disk (1), a ring (10) extends proportionally over the cylindrical surface area of a pot-shaped retaining part (6) and has a sleeve-shaped fastening section and a collar with holes parallel to friction rings (2,3) so as to protrude over a transition area (7) between the pot-shaped retaining part and the friction rings.
