Vehicle brake disc with cooling borings

摘要

The brake disc consists of a ring with a shaped inner edge (1) and a number of through apertures (2) in it. The axes of the holes form an angle of between 0 and 90 degrees, preferably between 25 and 65 degrees, with the plane of the disc. The axes of the holes may be basically tangential or radial to the disc. The direction of angling of the apertures may differ so than on each side of the disc, approximately the same number of holes form acute angles and obtuse angles with the brake block.
