Abstract
A differential is provided that includes a first and second side gear and a reaction block disposed between the first and second side gear. The differential further includes an engagement mechanism configured to have at least a portion of the engagement mechanism that is moveable from a retracted position to an extended position and a lock-out mechanism that is configured to engage the portion of the engagement mechanism. The lock-out mechanism is mounted to the reaction block. A reaction block for a differential in which a lock-out mechanism is mounted on the reaction block is also provided.
Claims17
A differential comprising:
- a first and second side gear;
- a reaction block disposed between the first and second side gear;
- an engagement mechanism configured to have at least a portion of the engagement mechanism moveable from a retracted position to an extended position;
- and
- a lock-out mechanism configured to engage and at least partially control the movement of the engagement mechanism,
- wherein the lock-out mechanism is mounted to the reaction block.
A differential comprising:
- a case;
- at least one pinion gear disposed in the case;
- a first and second side gear disposed in the case and in meshed engagement with the at least one pinion gear;
- a lockup means operable to retard differential action of the differential;
- an actuating means for actuating the lockup means;
- and
- a reaction block disposed in the case between the first and second side gears,
- wherein the actuating means comprises an engagement mechanism rotatable about an axis oriented generally parallel to an axis of rotation of the first and second side gear, the engagement mechanism including at least one flyweight, and wherein the actuating means further comprises a lock-out mechanism configured to engage the at least one flyweight of the engagement mechanism when the at least one flyweight is in an extended position, and
- wherein the lock-out mechanism is mounted on the reaction block.
A reaction block for a differential comprising:
- an engagement mechanism comprising at least one flyweight member having a least a portion thereof that is moveable from a retracted position to an extended position;
- and
- a lock-out mechanism comprising a pawl configured to receive the at least one flyweight member and at least partially control movement of the engagement mechanism,
- wherein the lock-out mechanism is mounted on the reaction block.
