Brake disk i.e. double-walled brake disk, for disgruntlement and/or vibration-damping modification of oscillatory system, has elliptical ribs provided on radial jets that are arranged opposite to each other

摘要

The disk has circular ribs (2) and elliptical ribs (3) that are arranged on a rear side of a frictional ring (1). The ribs limit cooling air channels (4) that lie on circular rings (21-25). The circular rings are concentric to a rotating center (M) of the brake disk, and are attached in a radial direction (R). The cooling air channels run in both running directions of the brake disk in a curved manner. Semi-axes of the ribs lie on the concentric circles. The elliptical ribs are provided on radial jets (11, 12) that are arranged opposite to each other.
