Power Divider/Inter Axle on Ice

my statement was more explain the reason why they say to not use the power divider on snow and ice. to say never use the power divider on snow and ice is as bad of advice as to say to always use the power divider on snow and ice.

 

Let's see the upper Midwest and Canadian tundra or the mid Atlantic ......

I think that sums it up.

 

not4hire, I've fought the battle you're fighting many times on here. And it's always the same... those who think they know, refuse to listen to those who actually do know and can explain why. And sadly, it's those who 'think they know' who are far more likely to bloviate about it and spread misinformation amongst the noobs and other impressionable sorts. No wonder trucking is such a mess, huh?

But thanks for fighting the fight, as futile as it seems sometimes.

 

Thanks for the encouragement. I have to admit though, I'm a bit of a masochist. Next topic; what pressure should my tires be?

 

Locked differentials while driving on ice: Two points are important to keep in focus, 1), the tractors pivot point is changed, 2), additionally causing a greater amount of force focused to the ground. i.e. this may work to get the combination vehicle unstuck. However, those same greater forces used by combination vehicle may cause an accident.

How: Under Steer, By changing the trucks pivot point, widens the turning radius (2 axles engaged Vs. 1 axle engaged) during the moment of a loss of traction. i.e. to counter steer, the driver needs to respond sooner/quicker to counter the greater forces applied by the two engaged powered axles that changed the tractors pivot point or face a loss of control. (to unlock the differential, will shorten the trucks turning radius.)

(im pretty sure, i got it right)

 

This tread is about power divider, not Differential Lock!

 

You Sir have no idea how an Interaxle Lock works. An IAL is not the same as Diff Cross Lock". Especially if you have diff locks on all axles. You can have diff lock on rear only and have Inter axle lock on that will give you a (3 way) 3 wheels with traction at all times. Have the diff locks on 2 axles will give you 4 way lock. We have tri drives with locks on all 3 axles, 6-way lockers. Just don't try making a sharp turn on ice when all 3 are locked.

 

Actually both are in the subject title, but youre right they are not totally the same thing.

 

Opps, thanks, didn't see interlock.

 

SMDH I have learned nothing from this thread except truckers never agree. Everyone has different opinions. I guess I will just drive really really slow then in bad weather. Agreed?
