ABSTRACT:
An internally air cooled brake disc assembly of the invention is manufactured by casting in small pieces to eliminate problems associated with casting large discs with integral air cooling passages. The assembly has a main disc member and a plurality of disc segments secured to the main disc member. The disc segments are separate entities and can expand and contract independently of each other, thus reducing distortion from thermal effects. Assembled outer surfaces of each disc segment are generally flat and provide an annular surface to be swept by brake pads. Inner surface of each disc segment has a plurality of ridges and at least one groove which spaces apart the ridges. The ridges contact the main disc member so that at least one passage is formed between the disc segment and the disc member to receive a flow of cooling air. When the disc segments are secured on each side of the main disc member, the disc assembly has a plurality of cooling passages on each side of the main disc member. An optional external fan means can be provided adjacent inner ends of each disc segment to provide a forced flow of air over the outer surfaces of the disc.
