TORQUE TRANSFER DIFFERENTIAL MECHANISM
When high speed clutch is pushed, the driving power always
moves from high speed side to low speed side, and controls
the driving power with the aid of the property which the
movement of driving power is proportional to the pushing
force of clutch.
In torque transfer differential, acceleration/decelation gear
always engages, and towerd to input speed from the
differential case, L.H. clutch engaging decelation gear is
revolutes in low speed, R.H. clutch engaging accelelation
gear is revolutes in high speed.
In the other hand, the housing side of R.H/L.H. clutch is
integlated to rear R.H. axle, if R.H. or L.H. clutch is opelated,
the driving power can be moved to right or left.
THE FLOW OF DRIVING POWER
(1) L.H.CLUTCH OPERATE
In order to boost the driving power of L.H. wheel, when
L.H.clutch is operated,a part of the driving power of R.H.
wheel flows to the differential case, the driving power
of L.H. wheel is boosted.
The result of this, the yaw moment occures in a right
to the vehicle.
(2) R.H.CLUTCH OPERATE
In order to boost the driving power of R.H. wheel,when
R.H.clutch is operated, a part of the driving power of
L.H. wheel flows to the differential case, the driving power
of R.H. wheel is boosted.
The result of this, the yaw moment occures in a left to
the vehicle.
