1.1 DESCRIPTION
The reduction in the differential is only very
limited. That is why a single-reduction differential
can be applied with a pinion which has a relatively
large diameter, creating a relatively favourable
load.
The load for the satellite gears, planet gear and
axle shafts is low.
Due to this low load the crown wheel and pinion
could be equipped with a helical toothing instead
of a hypoid bevelled gear.
The fitting dimension of the pinion is adjusted
using shims, the bevel gear-to-pinion backlash is
adjusted using adjusting nuts.
The pinion is supported on two bevel roller
bearings. The bearing pre-load of the bevel roller
bearings is adjusted using spacers which are
positioned between the inner bearing race of the
front bevel roller bearing and the shoulder of the
pinion.
The satellite-gear housing is supported on bevel
roller bearings.
The pre-load of these bearings is adjusted using
adjusting nuts.

Differential lock
The differential is equipped with a variable
differential lock.
The satellite-gear housing flange is fitted with
radial toothing at the right. The left side of the
selector sleeve is equipped with similar toothing.
This selector sleeve is also equipped with
keyways which fit into the keyways in the right
axle shaft. The left axle-shaft journal is also
equipped with keyways which fit into the internal
keyways of the planet wheel. The selector sleeve
(9) can be slid over the axle shaft using a fork (6).
This hinged fork is suspended from the axle (5)
fitted to the axle housing. The fork is operated via
the control rod which is activated by the engaging
cylinder (1). The connection between fork and
selector sleeve is composed of two sliding blocks
(7) which fit into a groove of the selector sleeve
(9). A spring clip ensures that the selector sleeve
and sliding blocks do not fall into the axle
housing, once the right axle shaft has been
removed. Air is admitted to and bled from the
engaging cylinder via a pneumatic valve which is
operated by a switch on the dashboard.
Once the engaging cylinder is pressurised, the
selector sleeve will move to the left.
Subsequently the toothing of the selector sleeve
will engage the toothing of the satellite-gear
housing.
This will create a rigid connection from the
satellite-gear housing via the selector sleeve to
the right axle shaft. As a consequence, the
remaining parts of the differential, such as the
planet wheels and satellite gears, can no longer
turn in relation to the satellite-gear housing. The
differential is now locked and both the left and the
right axle shafts are loaded with 50% of the
torque. If the engaging cylinder is bled using the
pneumatic switch on the dashboard, a spring in
the engaging cylinder will deactivate the lock.
