Inclined/rotated roll axis; handling effects.
Posted 05 March 2012 - 18:33
I was thinking of the effects of and inclined and/or skewed roll axis on handling in terms of load transfer. The poster in the fsae forum does a much better job of articulating the idea than I could, but I was trying to picture how the vertical and lateral location of the roll axis might cause load transfer even under constant throttle while cornering.
I do recall Mssr Rouelle discussing how an inclined roll axis can cause roll and yaw coupling (if memory serves)....
Thanks in advance for any insight, much appreciated.

Suppose a car is in a very long constant radius corner.
Taking the situation to the extremes, if the roll axis is directed perpendicularly to the car path, the suspension will not move unless the car is accelerating or braking.
In this situation, front-rear roll stifness distribution would become immaterial to the car's handling. Provided the chassis to be stiff, load transfer would be divided between front and rear axles following their mass ratio.

Note this is the steady state cornering case.
