Abstract
A brake disc (10) has a cover (12) made of a cast aluminium alloy and a brake ring (14) made of cast steel or cast iron. The cover (12) is cast onto pockets (22) which have a radially inwardly facing pocket opening next to the pocket edge (26), formed on the internal circumference (U.sub.i) of the brake ring, creating a radial distance (b) between the cover (12) and the brake ring (14). The pocket edge (26) is surrounded by the cast cover (12) and the pockets (22) are substantially filled with the cast aluminium alloy. Because of this method of connecting the brake ring (14) to the cover (12), umbrella-like distortion can be largely avoided.
Claims13
Brake disc with a cover (12) made of a cast aluminium alloy and a brake ring (14) made of cast steel or cast iron, where the cover (12) is cast onto anchoring pieces protruding radially inwards from the inner circumference (U.sub.i) of the brake ring (14), leaving a radial spacing (b) between the cover (12) and the brake ring (14), characterised in that the anchoring pieces are constructed as pockets (22) formed on the brake ring each having radially inwardly facing pocket opening with a pocket edge (26) bordering the radially inwardly facing pocket opening, where the pocket edge (26) is surrounded by the cover casting (12) and the pockets (22) are substantially filled with the cast aluminium alloy.
