ABSTRACT OF THE DISCLOSURE
A locking system for a differential gear including a
differential carrier having a cavity within which a pair of bevel gears
and at least one pinion gear which meshes with the pair of bevel gears
are housed, the bevel gears being adapted to be splined to axial shafts,
the locking system including a locking means positioned within the
differential carrier between the differential carrier and at least one of
the bevel gears, the locking means including locking teeth or spline means,
at least one of the bevel gears being formed with co-operating teeth or
spline means, cylinder means formed in the differential carrier and housing
an actuator positioned to cause movement of the locking means relative to
the carrier whereby the locking teeth or spline means on the locking means
engages the teeth or spline means on the one bevel gear to prevent rotation
of the one bevel gear relative to the carrier to thereby lock the
differential gear.
