Stuck on Ice

Interesting...sounds like I had it

Thanks for that Mike. At one time I thought I had a good search method, but I wasn't able to find what you did.

How did you do it?

I think I'm beginning to understand it better myself. I was wrong to say that the Hummer uses open diffs, but apparently the Torsen reaches a point at which it can't compensate any further and and goes "open". A one front and one rear on glare ice scenario would probably qualify. I think Detroit lockers are an option.

It's all in the link.... ..."+Gleason+Torsens+air&hl=en&client=" I just searched

It works by biasing the resistance to movement between left & right more closer to even. In other words it evens out the resistance to movement.

It's slightly wasteful because it's adding resistance to the traction wheel(s) as well as the spinning wheels, but it will get you moving. It's more effective with open-diff AWD than with open-diff 2WD.

VDC is essentially a more sophistocated version of the same thing. It allows momentary blipping of the individual brakes of the spinning wheels to bias some torque back towards the wheels with traction.

Some folks preffer a manual trans in snow because of the greater control it affords them. Likewise, some folks preffer open diffs with the option of applying some brake for the greater control it affords them.

Different strokes. -Danny

You have a wheel in the front and a wheel in the back that can give you forward movement. Seems like a good deal to me, over and above any FWD or RWD vehicle.

Caveat emptor! Anyway go buy a WRX--it has limited slip rear, and a center differential too. Very nice in snow.
