Abstract: 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.

A shaft lock (56) is provided to enable the user to selectively lock either or both of the shafts (32, 52) against rotation about their respective axes.

Abstract: An improved differential gear mechanism is characterized by a lockout mechanism (63) operably associated with a flyweight mechanism (53) and including a lockout member (65, 101) positionable, in response to an input signal, in a normal condition and a lockout condition. In the normal condition, the lockout member (65, 101) permits a flyweight stop surface (57) to move from the retracted position to the extended position.
