BRAKE DISK COMPRISING COOLING RIBS

摘要

The invention relates to a brake disk (100) provided with a plane-sided friction ring part (10), said part comprising an outer edge (11) and an inner edge (12) and radial long cooling ribs (13, 14, 15) between which ventilation channels (16, 17) extend. The aim of the invention is to improve the ratio of cooling capacity to dissipated power. To this end, cooling ribs (20, 21) are arranged between the radial long cooling ribs (13, 14, 15) and the inner edge (12), at a distance from the radial long cooling ribs (13, 14, 15).
