Abstract

A clutch actuation device includes two plates that can selectively extend and compress relative to one another to selectively engage or disengage a clutch. Each plate includes a plurality of grooves, each groove having a deep end portion, a shallow end portion, and a ramped or inclined surface between the end portions. Each groove on the first plate corresponds with a respective groove on the second plate to define a plurality of pockets. Within each pocket is an elongated member having a pair of curved ends and an elongated shaft therebetween. The curved ends sit in the deep end portions of the grooves. To extend the plates relative to one another, the first plate is rotated relative to the second plate. This causes the curved ends of the elongated members to pivot within the deep end portions, and the elongated shaft extends away from the ramped surface, separating the plates.
