Abstract
A composite, i.e., two element, two material clutch hub includes an inner sleeve of a heavy, high strength material to and about which is cast an outer element of a lighter, lower strength material. The sleeve typically includes a splined opening that is received on one or two complementarily splined shafts and a plurality of radially oriented pins or lugs or a discontinuous flange about which the outer element is cast. The outer element is splined to the friction plate of a clutch or other component. The high strength material is preferably, though not necessarily, steel and the lighter material is preferably, though not necessarily, an aluminum alloy. Alternatively, the sleeve may be a high strength aluminum alloy such as a metal matrix composite (MMC) and the outer element may be a lower strength, different aluminum alloy.
