Kind Code:
A
Abstract:
A locking differential having a collar member ( 35 ) fixed to rotate with the gear case ( 11 ), but free to move axially, and cooperating with a first sidegear ( 19 ) to define interdigitated lock members ( 41,43 ) operable, when the collar member is locked (FIG. 1 ), to prevent rotation of the first sidegear relative to the gear case ( 11 ). A spring ( 61 ) is disposed between the collar member and the gear case, to bias the collar member toward unlocked (FIG. 3 ). A plurality of actuation members ( 47 ) is provided, each having a first end ( 49 ) in engagement with the collar member, and a second end ( 51 ) in engagement with a ramp plate ( 53 ). When the actuating means is in the actuated condition, the ramp plate rotates relative to the gear case, and the actuation members ramp-up on the ramp plate and move the collar member from unlocked to locked.
