Brake disk for commercial vehicle

摘要

Each of the two halves (2a, 2b) of the brake disk (2) has an upper and a lower friction surface (5, 6) with joint elements (4) positioned between them and cams (7) arranged along the inner edge. The cylindrical hub (3) is equipped with matching cams (8) at its outer edge in order to be interlocked with the disk halves. U-shaped clamping elements (9) can be pushed onto the cams to secure their connection. A lock ring (11) is inserted into a circular groove formed by short grooves (10) in the lower area of the clamping elements.
