Abstract
A differential gear mechanism is provided of the type including a gear case (11) at least one input pinion gear (19) and a pair of output side gears (23) and (25). A clutch pack (35) is disposed between one of the side gears and the gear case and is operable, when engaged, to retard relative rotation between the gear case and the side gear. Disposed adjacent the clutch pack is a cam means (23,43,45,47) which is operable to ramp-up and engage the clutch pack. An engagement shaft (53) is in splined engagement (49,55) with the cam member and has an opposite end extending through the gear case and in splined engagement (59,63) with a retarding gear member (61). An actuator (69) includes an actuation member (71) which moves from a first position (FIG. 1) to an actuated position in response to an external signal (73) to bias the retarding gear into engagment with the gear case, thus retarding rotation of the engagement shaft relative to the gear case, and retarding rotation of the cam means relative to the gear case, to cause engagement of the clutch pack.
