Locking Diff?

[ghetdjc320]

In an auto locker it still allows a wheel to “differentiate” though and spin faster unlike most auto lockers which are typically spools when locked.

If it’s allowing different wheel speeds across the axle in the “locked” mode, then it’s not a locker. There’s different kinds of auto-locker, and some of them do require a speed differential to lock in, while others operate more like a spool that disengages under low load. I’m sure there’s other varieties out there as well... but if they allow for slip between the axle shafts, then it’s a limited-slip diff, not a locker.

A limited slip alters the torque bias. Depending on the model, a Truetrac could be as much as 3.5:1. This means that it’s going to bind up so that it pushes 3.5 times as much torque onto a “stationary” wheel as it does on the free-spinning wheel.

 

"as much as 3.x..." or "up to 3.x..."

 

I see this language often and then my understanding starts getting muddled.  In a Torsen style differential, is the torque biasing capability progressive? 

 

Or does it try to transfer the full 3.x all the time?

I doubt the truetrak is 3.5 to 1 when new. Maybe.....

 

The original TorSen. which was the DualDrive Differential never had to spin before working.

I’m just referring to your typical Detroit, Grizzly and lunchbox style lockers. In a corner, the outside wheel can spin faster if needed but it never allows that wheel to spin slower than the inside wheel. These are tried and tested lockers.
