Abstract
Apparatus for driving a clutch plate includes a drive pin comprising a shank and a drive head rotatably mounted thereon. In a preferred embodiment, an intermediate clutch plate of a two-plate heavy duty clutch is axially but non-rotatably movable with respect to the clutch flywheel. The flywheel contains an axially extending annular flange from which the aforesaid shank fixedly extends radially inwardly. The drive head, rotatably mounted thereon, is disposed within a recess of the clutch plate for driving engagement of the plate. The apparatus provides a self-aligning clutch plate drive system which substantially minimizes the declutching failures experienced in conventional non-self-aligning drive systems. A friction member resiliently holds the drive head to the drive pin shank for ease of handling and installation of the apparatus. Typically, clutch plate drive recesses comprise slots having radially extending walls positioned parallel to the clutch plate axis of rotation. An alternate preferred embodiment of the clutch plate recess utilized herein comprises radially extending walls angularly offset from said axis.
