well, you keep telling peeps what size tyres to fit on a disco and why petrol hippoos "cant be as bad as that" and where peeps can find green lanes, James. Yu will get sick and tired of repeating yoself ad-naseam.

Me - this is an interesting enuf site with lots of original discussions to keep me happy, without the repeat Q's.

I am sure yu wont mind having all the dumb-arsed repeat questions put in your direction :rolleyes:

But it's the friction from the heat produced as the liquid is agitated through slip that makes it 'stickier', if you like. Yes, there is a difference in rotational speed between the front and back wheels, the back wheels turning faster by a marginal percentage, and even if this small difference warms the liquid, its the temperature above a certain level that makes the liquid nearly solidify, not just the fact that it gets warm. Apparently, although I've not had a chance to experience this yet, but the vcu gets very hot when this happens.

just noticed this........ there's no difference in rotational speed on road, the back wheels will be turning at the same speed as the front. The point is this situation the back wheels aren't being driven by the rear diff they are driving the diff. No matter what resistance there is in the VC it is causing drag not drive.

ask away im very patient :D:D
 
Here's a good question (I think) if, on Tarmac with no wheel spin, it drives the front wheels only and just drags the rear around, this makes it behave like a front wheel drive slush box! Yes? The vcu wouldn't need to do anything, and it'd be front wheel drive! With all the soggy characteristics:) this seems to be the theory! So my question is, why did they design in a ratio difference to make it behave like a front drive car when you're all saying its front drive not four wheel drive? Answers on a post card
 
Well i'm finding it very interesting reading through this. I recon im getting an idea of how it works now but shall re-read again for better understanding.

I did also ask in the greenlane bit if there were decent freeby suitable lanes near hull, got no answers but as im not very good with my where in england is places as im a caber tossing haggis chaser.. Ah well.

have yu read the definitive guide to VCUs in the FAQ section? it even comes with pics :rolleyes:

Honest answer, No i haven't. :eek:

Shall go look, would hull lanes fall into one of the massive threads running already in the greenlane section? Genuinely have no idea :(

Yes? spose so The vcu wouldn't need to do anything, yes it still has to slip to prevent transmission wind up and it'd be front wheel drive!

don't know why they thought it would be better to give it a front bias.
The thing is the difference in ratio is/was only 0.8% so the slightest scrubbing of the front wheels particularly in a turn is enough to allow prop speeds to alter and progressively bring in the rear as a driven axle.

merely turning a corner could do it too, because the inner wheels would be going slower than the outers
