The question is - Does an NP 229 have a differential?
Obviously, a differential is anything that allows differential motion between the 2 outputs, so in a way the VC is a differential. But I'm talking about a real gear-to-gear differential.
Looking at the exploded view here http://www.bjsoffroad.com/CartGenie/image.asp?pid=1121 has not helped me much. I can't seem to follow the flow of power through the dissected views.
And reading the last few comments in this old thread
http://www.ifsja.org/forums/vb/showt...9+differential has piqued my interest.
I've read that the difference between the NP228 and NP229 is that the VC replaces the differential in a NP229. However, if that is true, then I agree with GWChris' argument as follows.
"Without a mechanical diff, you would have to drive one axle directly (like some of the cheap 4WD systems), and then the viscous coupling would send a little tourque to the other axle if there was a speed difference between them.
That's not how this works. It has an open diff with a viscous coupler in addition. If you drain out the secet fluid, then you just have an open diff left and it works like a NP228."
My NP 229 does not operate as if there is simply a VC in the front shaft. I do not have to have slippage in the rear wheels to get torque at the front.
Is the VC more complicated than just a set of parrellel plates in silicone fluid? Does it also have a mechanical differential function with the plates making it a limited-slip?
Can someone please shed some light on this? It's driving me crazy (and that's a short trip).
Thanks
