Patent ID: 8037980

Claim:
A brake disc/hub connection for connecting a brake disc comprising friction rings connected via webs with a hub, the brake disc/hub connection comprising: a pot-like, hollow cylindrical section of the hub, at one end of which extends a radially outward disc section; support elements arranged about a radially inner peripheral region of the brake disc; axially extending support webs which extend from the disc section into a region in which the brake disc is seated on the pot-like, hollow cylindrical section of the hub, said axially extending support webs forming cams that are arranged about an outer peripheral region of the pot-like, hollow cylindrical section of the hub, said cams engaging between the support elements to secure the support elements on the hub in a peripheral direction; and wherein the cams are connected only via one narrow connecting web at each cam radially to the outer periphery of the pot-like, hollow cylindrical section of the hub, whereby air flow ducts are formed radially inward with respect to the support webs and the support elements, wherein the connecting webs have a width in a circumferential peripheral direction less than 50% of the extent of the support webs in the circumferential peripheral direction in a region of the brake disc.
