Vehicle brake disk has disk body with pyramid-shaped lugs on internal edge

摘要

The brake disk consists of an annular brake disk body (1) and a dished support body (2) in a positive fit with it. The disk body has pyramid-shaped lugs (3) on its internal edge, surrounded by pockets (5) in the wall (4) of the support body. The positive fit between the disk body and the support body is achieved by internally hydroforming and upsetting the wall.
