Abstract
A disc/hub connection for connecting the brake disc with the hub is provided. The brake disc has support elements on the inner peripheral area and the hub has cams. The hub has a pot-like, hollow cylinder section that merges with a disc section that extends outward radially. The disc section has support rods that extend outward axially and that extend into the area where the brake disc contacts the pot-like section and that merge with the cams that, in turn, engage between the support elements of the brake disc. The support rods radially-placed inside the extension of the brake disc do not, or only by way of thin connection rods, connect radially with the outer periphery of the pot-like section.

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.
