Abstract

PROBLEM TO BE SOLVED: To manufacture a drum hub having sufficient predetermined strength, thermal conductivity, and abrasion resistance without an assembly process by casting a hub part and a brake drum part integrally from pseudo-flake-like graphite cast iron. SOLUTION: A drum hub A is integrally constituted of a hub part H to which a drive shaft is attached and a brake drum part D with which a brake shoe part B is contacted. Then, a steel wheel W is attached to the drum hub A through a bolt and nut, and a tire T is mounted to the wheel W. Parts which is the hub part H and the brake drum part D are formed from pseudo-flake-like graphite cast iron (FCV cast iron). Thereby, the hub part H is allowed to have the strength substantially middle of nodular graphite cast iron (FCD cast iron) and flake graphite cast iron (FC cast iron), and the brake drum D is also allowed to have thermal conductivity and abrasion resistance substantially middle of the FCD and FC cast iron on the nature of the FCV cast iron.
