Abstract
Indexing drives associated with a transmission each include a housing having a plurality of guideways, actuators slidably mounted in the guideways and a carrier with follower elements. The actuators include drive elements which can extend to the follower elements. The follower elements are movable across the drive elements and the drive elements are movable toward and away from the follower elements. The drive elements include convexities and the follower elements include concavities. The concavities are spaced from one another and the convexities are spaced from one another such that when one of the concavities is fully engaged with one of the convexities, two other of the concavities and two other of the convexities are sufficiently aligned to be partially engageable. The follower elements are severally arranged to provide cylindrical surfaces with concavities, circular surfaces with concavities and longitudinal surfaces with concavities. The transmission includes gears, clutches engageable with the transmission gears, clutch control elements extending to operatively engage the clutches and linkage engaged with the carrier of the indexing drive and the clutch control elements.
