Abstract
A brake drum is provided that includes an open end and a hub end, with a braking section extending generally transversely from the open end to join with the hub end. A plurality of first-indented sections are present on an outer surface of the braking section. A transition section extends from the braking section to the hub end. A plurality of second indented sections are located on an outer surface of the transition section. A plurality of third-indented sections or openings can be present in the hub end between wheel lug openings.
Claims28
A brake drum comprising
- a cylindrical drum structure having an open end and a hub end, said hub end being partially closed to form a hub receiving opening in a radially central portion of said hub end,
- a braking section extending generally transversely from said open end toward said hub end,
- a transition section extending from said braking section to an intersection with said hub end,
- a plurality of first-indented sections on an outer surface of said braking section, each of said indented sections extending from said braking -section onto said transition section,
- a plurality of second-indented sections on an outer surface of said transition section, and a plurality of wheel lug openings in said hub end.
