Ventilated brake disc for motor car, has connection node and rib element which are arranged in periphery of brake disc to locally change rigidity of brake disc in circumferential direction or in radial direction

摘要

The brake disc has friction rings (4) which are spaced apart from each other, and the radially running connection ribs (2) that are arranged between the friction rings. The connection node (8) and rib element (9) are arranged in the periphery of the brake disc to locally change the rigidity of the brake disc in circumferential direction or in radial direction. The rigidity of the brake disc in axial direction concerning the bending from the plane of the brake disc is not influenced.
