2) When right and left wheels turn at different speeds .
When a speed difference occurs between the right and
left wheels, the VC housing and VC hub turn relatively at
the same speed difference as that of the rear drive shaft.
Because of the shearing force caused in the silicon oil, a
differential torque is generated, which controls differen-
tial operation (idle rotation) . For example, if the left
wheel turns idle due to a difference in the road resis-
tance, a speed difference occurs between the right and
left wheel . Since the VC is installed between the right
and left wheels, a differential torque is generated in the
VC corresponding to this speed difference, and this
differential torque is transferred from the left wheel to
the right wheel. Accordingly, a greater driving force is
transferred to the right wheel which is rotating at a
lower speed as shown in Figure 7 .
The component parts of LSD ASSY are not available as
piece parts.
Therefore, it is recommended to not disassemble LSD
ASSY.
