I made some images with the steering moved and tilted.
I changed the position of the link between the wheels. I moved it 100mm back and there is a small difference in angle. Hard to see, but tit is there.
also did i put the wheels under an angle. It makes it a bit harder to see.
arrow is pointing to the front of the trike.
I raised the mounting point of that link, so the ackerman would be biger and more visible.
I looked ad caster of 10 degree and the difference isn't worth to look ad, that small is it.
Alan's design has an ackerman that reacts on the amount of steering. It must be a combination of both to activate it, but he can change it under each angle. So the steering input influences his ackerman and therefore always point the right direction.
This design only reacts on tilting. So as it tilts, it is activated and the amount is not changed by the amount of steering input.
That means that i will go back to the first setup where I splitted the link between the wheels and use that as ackerman setup.
By doing this, i remove the ackerman from the tilt and can i change the ackerman by changing the steering angle. sockerman will be set the conventional way. Tilting will not have any influence on the ackerman, because it is in the same plane as the top bar.
I amn happy that the small amount of caster, has so little effect on the steering. THat makes that i don't have to look ad that and can keep it for now like this and work on it.
