A differential mechanism of the type including a pair of annular driven clutch members spring-biased into driven engagement with an annular central driving member arranged colinearly therebetween, and holdout ring means operable when one of the driven shafts overruns the other for maintaining the corresponding driven clutch member in a disengaged condition relative to the driving member, characterized in that each of the axially split resilient holdout rings is normally biased radially outwardly in an expanded condition into frictional engagement with the outer side wall of the driven clutch recess in which it is rotatably supported. Pilot means contained solely within the driving member are provided for piloting the adjacent ends of the side gears upon which the driven clutch members are axially slidable. According to the preferred embodiment, the adjacent ends of the side gears are journalled in the central cam member, the spring biasing means being arranged either externally or internally of the driven clutch members. According to an alternate embodiment, the piloting is effected by a telescopic connection between the adjacent ends of the side gears. |
