A starter-generator device for a work vehicle having an engine includes a gear set for transmitting power, one or more clutch portions configured to selectively interact with the gear set, an actuator device to power movement of an armature only in a first direction, and a linkage having a first portion extending axially and having a neck region formed as a permanent bend and having a bend radius. The linkage also includes a second portion extending radially from the first portion to a distal end. An actuation pin is connected to the distal end and to the clutch portion such that movement of distal end causes corresponding movement of the clutch portion. Powered movement of the armature moves the distal end in one direction. An elastic return force of the linkage moves the distal end in an opposite direction.

Integrated starter-generator device with unidirectional clutch actuation utilizing biased lever assembly

A drive assembly for a work vehicle has a drive housing including at least one housing element forming a reaction member, a drive shaft rotatable about a drive axis, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes at least one clutch arrangement having at least one clutch ring configured to selectively interact with the planetary gear set to effect a rotation speed of the output element. At least one actuator is configured to axially drive the clutch ring along the drive axis. A retention mechanism is configured to retain the clutch ring at an axial position along the drive axis. The retention mechanism includes a detent ball, a detent groove and a resilient member configured to urge the detent ball into the detent groove to retain the clutch ring at the axial position.
