Limited slip differential
*
With unfavorable road conditions, the
drive forces that should be transferred
may not be accommodated by the
traditional differential, and therefore
one wheel may spin. This wheelspin is
largely avoided by the limited slip differ-
ential (cut-off value approx. 25X).
Under actual driving conditions, this
means better traction characteristics
when starting and accelerating (under
adverse road conditions) and during
performance-oriented driving on
winding roads.However, in the case of extremely
dynamic driving, the vehicle may tend
at the same time to spin around its
vertical axis in the vehicle center of
gravity on road surfaces with different
adhesion characteristics. Controlling
this rotation tendency places greater
demands on the driver and therefore
requires special alertness.
The limited slip differential is active
during actual driving without the driver
taking action.
