Traction Control

[mcderd]

hey,

just wondering if anyone knows where to get an explanation of how, exactly traction control works in both f1 cars and normal road cars. its the whole transfer of torque thing that i don't get... how is <700bhp moved about?!

SOUND!!

You could try this:

* F1 Technical
* How stuff works
* F1 official site

looking for something a little more exact than what they can offer... they don't really talk about it...

what i wanted to know was how the mechanical aspect of it worked. how is it possible for mechanical linkages capable of distributing the rotation between the two wheels. does the rotation of the shaft stop to one wheel allowing the spin to stop and the power redirect to the wheel that has traction?

if so, how does this work?

Thanks... (its not the easiest thing to find out)

Well, I hope this helps:

* http://en.wikipedia.org/wiki/Differential, Wikipedia article on differentials, if this is your question. How stuff works explains several types.

* F1 differentials are... different (sorry, I couldn't resist).

* Formula One.com explains that they are limited slip differentials, or this is what I understood.

* You can find a list of types of differentials that "have stood the test of time on racing" on Milliken and Milliken (link to Amazon listing) that maybe you can check at your library.

* Finally, there was a thread about CVT (which are forbidden) that you may find interesting and a really short explanation on differentials, both on this site.

I believe traction control through electronic controlled differentials is forbiden, so modulation of engine and braking of wheels (this last one I am not sure) are what is left in F1.

Maybe somebody can help with something more specific.

There's an SAE paper on Traction Control development in F1. Check it out. sae.org
