Abstract
A brake disk for disk brakes, in particular of land vehicles, has a friction ring received by a support section, formed, for example, by a portion of a wheel hub. The support section has an out-of-round outer formation on which the friction ring is seated torsionally tight with a centric opening of complementary inner out-of-round formation. The friction ring, and preferably also the support section, is comprised of cast metal and the friction ring is cast onto the prefabricated support section to form a cast connection between the friction ring and the support section. The cast connection between the friction ring and the support section is such that upon an initial heating of the brake disk the cast connection becomes ruptured and the friction ring becomes separated from the support section.
Claims14
A brake disk, comprising:
- a prefabricated bearing hub including a support section having an out-of-round outer formation;
- and
- a friction ring received by said support section and having a central opening with an inner out-of-round formation complementary to said out-of-round formation of said support section and with which said friction ring is seated torsionally tight on said out-of-round outer formation of said support section;
- wherein said friction ring comprises cast metal cast onto said support section to form a cast connection between said friction ring and said support section, with said cast connection between said friction ring and said support section being such that upon an initial heating of the brake disk said cast connection becomes ruptured and said friction ring becomes separated from said support section.
