STRUCTURE AND FUNCTION

DESCRIPTION
The driving power for the engine (1) is transmitted through the flywheel to the converter (2). The converter (2) uses
hydraulic oil to convert the torque transmitted by the engine (1) into driving power. The converter (2) transmits motion to
the drive shaft of the transmission (3) and to the drive shaft of the hydraulic pump (4).
The transmission (3) has two hydraulically actuated clutches that can be selected by an electrically controlled gear selec-
tor. It also has a manual gear selection (four forward gears and four reverse gears).
The driving power is transmitted from the transmission flanges (3) to the front (5) and rear (6) axles through the drive
shafts (7 and 8).
The driving power transmitted to the front (5) and rear (6) axles is reduced by the differentials and then transmitted to the
planetary gear through the differential shafts.
