Abstract:
1. A locking differential mechanism for driving a pair of spaced collinearly arranged output shafts ( 104 , 106 ) from a main drive shaft, comprising: (a) a casing ( (b) an annular central driver member ( (c) a pair of annular side gears ( (d) a pair of annular clutch members ( (e) spring means normally biasing said clutch members toward engaged positions relative to said central driver member, said spring means including a pair of compressions springs ( (f) center cam means operable when the rotary velocity of one output shaft exceeds that of the other output shaft above a predetermined value for axially displacing toward a disengaged position the clutch member associated with said one overrunning output shaft, said disengagement means including: (g) holdout means operable from an inactive position to a lock-out position to retain the overrunning clutch member associated with the overrunning output shaft in the disengaged condition as long as the rotational velocity of the overrunning output shaft exceeds said given value, said holdout means including;
