DESCRIPTION
●
The driving power for the engine
b
is transmitted through the flywheel to the converter
c
. The converter uses hydraulic
oil to convert the torque transmitted by the engine into driving power. The converter transmits motion to the drive shaft of
the transmission
d
and to the drive shaft of the hydraulic pump
e
.
●
The transmission
d
has two hydraulically activated clutches that can be selected by an electrically controlled gear selec-
tor. The same switch also controls the four speed clutch packs.
●
The driving power is transmitted from the transmission flanges to the front
f
and rear
g
axles through the drive shafts
h
and
i
.
●
The driving power transmitted to the front
f
and rear
g
axles is reduced by the differentials and then transmitted to the
planetary gear through the differential shafts.
