An improved differential gear mechanism is characterized by a lockout mechanism ( 129 ) operably associated with a latch member ( 119 ) that cooperates with a flyweight mechanism ( 53 ) to retard differentiating action in the differential gear mechanism. The lockout mechanism ( 129 ) includes a lockout member ( 131 ) positionable, in response to an input signal, in a normal condition and a lockout condition. In the normal condition, the lockout member ( 131 ) permits the latch member ( 119 ) to move freely between a locking position and an unlocking position. In the lockout condition, the lockout member ( 131 ) prevents the latch member ( 119 ) from moving into the locking position. |
