The sun gear is fixed to the synchro-hub
which carries the selector sleeve.
Shifting is effected by means of the selector
sleeve via the synchro-ring, coupling body 1
or coupling body 2 to the synchro-hub and
then to the sun gear.
Clutch-hub 2 is bolted to the housing cover
and locks the sun gear in low range
operation.
Design of additional shift
stage
The speed reduction of 1.54 is effected via a
simple planetary gear set whose planet
carrier is integrated into the Torsen
differential housing.
The drive torque is transmitted to the internal
gear via the hollow shaft. The internal gear
engages with the planetary gears and is also
fixed to the coupling body 1.
The shift actuation is effected via the
hydraulic regulator under electronic control
and monitoring.
