Very informative Anoop. I never gave thought to train curves as I thought that since curves of tracks are not sharp, they may not need differential speed at wheels. Also, I believe that tracks are placed at different levels on a curve so as to combat the centrifugal force of the moving train.
Thanks a lot.

The centre differential in an AWD car behaves exactly in the same way (e.g. the Fortuner, Grand Vitara, Pajero). Some AWD vehicles, however, don't use a centre diff to transmit power to the opposite axle, but make use of either a clutch pack or a viscous coupling to even out the difference in rotation between front and rear axles (e.g. the Tucson, CR-V, XUV500).

What I can't figure out is how a variable and unequal torque split happens in AWD systems, whether with or without centre differentials employed. Under normal driving conditions, a differential is known to have an equal torque split between 2 wheels running at the same speed on similar surfaces.

• How then, does a car achieve unequal torque split between front and rear axles, esp. in vehicles with a centre diff (e.g. Porsche Cayenne, VW Touareg)?
• How does it help to have an unequal torque split? and
• How does one quantify / calculate this torque split?

Came across this nice thread when reading about vehicle dynamics. Can you please post the rest of the article a the links do not exist anymore?

This was so long ago! Seems to have gone.

I don't have the third page as I never wrote that. I have no contact with the other contributors too!

A reverse Google search also didn't throw up anything.

This was again posted on reddit and I found it quite useful and easy to understand even after decades.

I wonder if there is anythink similar for multi link suspension setups and how they work.
