Multiple-section brake disc esp. for motor vehicles has two friction rings of steel or ceramics, and drive plate, spacers, and fasteners of steel, carbon, or alloys

摘要

The brake disc has two friction rings (1,2) connected via fasteners (8) to a central drive plate (3). Spacers (6) located between the friction rings in areas acting with friction linings, are fitted into radial long bore-shaped passages in the drive plate. The spacers are positioned in at least two radial rows. The spacer ends are stud-shaped, and engage positively into corresponding openings (9) in the insides of the friction rings, and the rings engage on a collar next to the ends.
