Abstract
A clutch plate assembly includes a central axis, a clutch plate with a first friction surface and a radially outer depressed portion, and a friction material ring. The friction material ring is bonded to the first friction surface and extends radially outside of the first friction surface such that an outer portion of the friction material ring is axially aligned with the clutch plate radially outer depressed portion. In an example embodiment, the first friction surface is disposed at an acute angle to a plane orthogonal to the central axis. In some example embodiments, the first friction surface is conical. In an example embodiment, the radially outer depressed portion is conical and axially offset from the first friction surface. In an example embodiment, the radially outer depressed portion is manufactured by machining, stamping, or coining.
