TORQUE TRANSFER DIFFERENTIAL
The torque transfer differential consists of differential mechanism,acceleration/decelation gear and two
pairs of wet multi-plate clutch. The hipoid gear oil is used to lublicate differential part, ATF-SP III is used
to lublicate torque movement part (acceleration/decelation gear and clutch).

DIFFERENTIAL MECHANISM
When the vehicle turns, admits the revolution difference between inner race and outer race.
ACCELERATION/DECELATION GEAR
Have the revolution speed of right and left wet multi-plate clutch to accelerate or decelate as oposed
to the revolution speed of right wheel.
WET MULTI-PLATE CLUTCH
Have the torque to move from high speed wheel to low speed wheel.
L.H. clutch operate: decelation geer have the torque to move R.H. wheel to L.H. wheel.
R.H. clutch operate: accelelation geer have the torque to move L.H. wheel to R.H. wheel.
The movement of torque is dependence on pushing force of the clutch.
