  • Integrated starter-generator device with unidirectional clutch actuation utilizing biased lever assembly
    Patent number: 11719209
    Abstract: 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.
