Hello,
I have a question about Ackermann percentage calculated by Lotus Shark.
I have read the software help and I have understood 100% Ackermann is full Ackermann.
Before I use the software, I have done the traditional drawing to establish angle at which steering arm should be mounted to obtain full Ackerman but with this configuration Lotus Shark gives only 45% Ackermann.
I have defined the angle of steering arms drawing lines along the arms from the trackrod ends, via the kingpin axis to intersect at the centre of the rear axle line (this approch is valid because the rack and pinion lie on a straight line joing the two trackrod ends each other).
I have used some software template and Ackermann percentage is very different from traditional drawing method.
Can you help me? Where is the mistake?
Best Regards
M.R.
