RE:A New Look at Torsens

["Dave Eaton" <Dave.Eaton@clear.net.nz>]

ummm, weren't you the person who has so stoutly being saying that chassis is
not a factor in this???  i appreciate the public retraction...

also, you continue to misunderstand that the *fixed* centre diff (not just
the torsen) continually varies torque front and rear through a corner.  so
your statement "a torsen with torque applied to it, ALWAYS varies the BR
when you aren't in a straight line", could equally well be "a locked centre
diff with torque applied to it, ALWAYS varies the BR when you aren't in a
straight line".

with all due respect scott, your baseline understanding of either the torsen
of a simple locker is well off.

a good reference for you would be chapter 10 of "car suspension at work" by
jeff daniels which details the generation 1 quattro system, and how it works
dynamically.

Depends on wheelbase, cf, rate of acceleration, weight of vehicle and radius
of turn.

>Is it a three-state device (rear 75/25 front, or front 75/25 rear, or equal
>50/50), or does it continuously vary the ratio?
Varies as you add slip angle, engine torque, weight transfer cf, etc.  As
you
unwind the steering wheel, the ratio varies again.  Think of it this way, a
torsen with torque applied to it, ALWAYS varies the BR when you aren't in a
straight line.
