Abstract:
A electric locker differential assembly includes a first and second side gear. A pinion gear set is disposed between the first side gear and the second side gears. An engagement shaft includes flyweights disposed on the engagement shaft which are moveable between retracted and extended positions to lock and unlock the differential assembly. A lockout shaft includes a pawl disposed thereon. An electrical adjustment mechanism includes an actuator operably connected with an adjustment nut or rod. An electrical adjustment biasing spring includes a first leg retained by the adjustment nut and a second leg connected with the pawl wherein movement of the adjustment nut by the actuator varies a biasing force applied to the pawl.
