Steering axis or king pin angle
Harvey mate, I am amazed by your statement in this thread as follows : -
06/18/03, Quote ---- I'll explain it better. Looking from the front of the car at the right side wheel. The steering axis or kingpin inclination, is a line drawn down from the top strut bearing, down through the bottom ball joint, to meet the ground in the centre of the tyre contact patch. This is the line that the wheel steers around. ---------------------------------- It is the fact that the line of the steering axis or king pin inclination does NOT meet the ground in the CENTRE of the tyre contact patch as you so exactly state that provides correct steering geometry. If what you state was true there would be no caster angle and no offset. In fact what you later describe would not take place. In the usual set up i.e. a car with positive caster, the line of the king pin or steerin axis will meet the ground at a point ahead of the centre of the tyre contact patch so as to provide caster angle and will also be inside or outside the centre point to provide offset. I have looked at the drawing you have provided but this in no way corrects your statement and in fact illustrates your error in respect of offset. Cheers, have a Cooper's. Trevor.
