Subject: Free limited slip differential. Was: Locking differential..?
Content-Type: text/plain; charset=iso-8859-1
In the military terrain driving education we were taught to
use the brakes as a way of balancing motor power. On
the 4x4 (or 6x6) many times applying limited braking
at the same time as power would help negotiate a challenging
terrain.
Now on the 2WD vanagon, pushing the brake pedal is counter productive
as it will stop also the non-driven wheels. One can pull the handbrake
to prevent a spinning wheel. It will of course brake both rear wheels,
but it can somewhat help stabilize power on difficult/slippery surfaces.
It works best if applied before anything starts slipping.
(probably due to difference between static and dynamic friction)
A means of engaging the brake on just one wheel might be handy also.
Would need the cables from both wheels to be pulled to the front.
