ABSTRACT:
Air cooled brake disc having first and second disc-shaped face portions with each face portion having an outer braking surface and an inner surface. A plurality of radially disposed webs extend between the face portions from an inlet adjacent an inner portion of the disc to an outer portion of the disc, the webs defining with inner surfaces of the face portions radially extending cooling passages within the disc. A plurality of radially disposed cooling fins extend from opposite inner surfaces of each passage. Sums of cross sectional areas of inner and outer cooling passage portions defined in part by the cooling fins are generally equal to reduce air flow velocity variations within the cooling passages. In one embodiment, a clearance space extends between opposed edges of the fins adjacent a central diametrical plane of the disc.
