Torsen repl for VC   Message List

Re: Torsen repl for VC


Gday Mark,

Sorry Mark. I was deliberately trying to get down to the root
fundamentals on this without diflocks being involved, they only muddy
the waters even more, the only variations I concentrated on were a VC
and solid shaft comparison. Hence my specifically composed comments and
questions.

So from your reply, I take it you mean that with a VC, nearly full
torque is available at whichever wheel set is gripping, which for a VC
is clearly not both at the same time (i.e., if rear set are gripping,
there should be little or no torque transfer to the front wheel set by
the VC). Conversely, with a solid shaft in the same scenario and rear
wheels gripping AND the solid shaft coupled, does that provide full
torque to both wheel sets or does it equally divide (split) available
torque between both gripping wheel sets? That is the conundrum. Any
thoughts please?

Cheers.

Ken

My apologies folks, I see now that a Torsen replacing the VC will not act as a Torsen would in a vehicle with a traditional center differential. Silly me....
