AN IMPROVED ROTOR FOR SELF-VENTILATING DISC BRAKES

摘要

A disc brake rotor which includes a central hub (1) co-axial with surrounding annular rings (3) which form brake bands for engagement with brake pads. The rings (3) are supported in a parallel spaced apart configuration by a plurality of pillars (6) between them which are arranged in clusters to form a series of overlapping edges and channels. In use of the rotor cooling air is drawn radially outward through the channels as the rotor turns. The pillars (6) are disposed in staggered tiers to facilitate the distribution of support against heat distortion.
