Rob,

The difference in speed of the front wheels in a turn is caused by the
friction between the tires and the
ground, plus the distance traveled by each. The differential gears are to
allow this to happen. If the
wheels are on a slick surface, one of them will slide causing a severe lack
of traction. Result BOOM.
Just my understanding and experience in crashing. LOL

Espen,

This unit is not designed like "all" LSD or lockers.

I'll try explaining it another way.

You're going down an icy road and you come to a corner where you want to
make a right turn.

You turn the steering wheel to the right.

The inside wheel slows down while the outside wheel speeds up.

The spur gear attached to the axle on the curb side of the turn slows down
while the spur gear attached to the axle on the outside
of the turn begins to turn faster. The coefficient of friction of the blocks
against the spur gears is NOT high enough to force the
inside wheel to turn and force the vehicle to go straight. It is low enough
to allow them to turn at different speeds yet high
enough to force them to turn in unison on slippery surfaces going straight
ahead.

The "secret" is getting the spring tension correct to allow this to happen!

Think about this; who would be stupid enough to sell a unit that would stop
you from making turns safely under any conditions?

Regards,

Yes and all of the above is just fine when you have traction on a asphalt
road, then all LSD or lockers will release due to the
frictions the tires have to the surface, however on a snowy or icey road
your traction will be minimal and the tires will have no
friction to the surface.
So what will happend ? the LSD will not release but lock up, and belive me,
you will not be able to make that turn.

Please prove me wrong :)
