## Main Question or Discussion Point

How would I calculate what % of torque is transferred to front and rear wheels in a 4WD?

The split happens at the lay shaft. Crown pinion(

For Rear wheel, Torque = gear box ratio * Rear CP ratio / 2 * Final reduction

For Front wheel, Torque = gear box ratio * 4WD ratio * Front CP ratio / 2 * Bevels reduction ratio

I have split CP shaft torques into 2 while transferring to wheels but for lay shaft where it was CP and 4WD gears attached on either ends, I have not split the torques.

I suppose it has to be split but I am not sure in what ratio as CP rear ratio and 4WD ratio are different.

Can anyone help me on this split?

Regards,

RJ
