I went with the ackerman first and it works.
This is as it is leve, The wheels are both parallel to each other.
in the folowing immage with a tilt of 30 degree, you see that the inner wheel tilts more and the other wheel points out.
I can change both angles very easy. As you want to make the tilt difference smaller, you need to keep the mounting points ad the bottom arms in the middle, closer to each other.
Than the wheels will have less tilt difference.
In the next image, you can see the way i changed it so the ackerman changes in a corner.
The red lines show the hight difference of the 2 rotation points. The higher the difference, the more the wheels start to point out in the front as it tilts.
There are 2 ways to adjust that. You can move it up or down, but you can also move the link between the wheels in the direction of the blue arrow. The more to the back, the smaller the angle between the wheels will be. This way i can finetune the Ackerman on the trike. I can change it, to the wheel base. By looking in cad, what the position needs to be, i can adjust it to a wheel base, if you want an adjustable wheel base.
As you don't use an adjustable wheel base, it can make it so it has the right length for that trike.
I need to look ad tilt and ackerman. to see what settings are best. With the ackerman i set it so the points cros ad the right point adn with the length of the bottom arms, i can set the rotation point on the right spot.
the arm length is only one time and will be fixed. The ackerman can change from trike to trike depending the wheel base.
Small tilts, so as the road is slightly tilted, will not give any problems. That ackerman difference is just way to small to notice it.
This system also only works as you tilt. But with the limited steering angle of the front wheels, you need to tilt. With this setup i can set it for a tilt of close to 35 degrees. But it depends on how yopu do the rotation points if you can do more or less. I will focus for about 30 degrees tilt.
The tilting system lowers the friction compared with a normal trike a lot. Tires will wear a lot less and the corner speed will go up.
with the ackerman compensation, this friction will be even lower and even go faster trough a corner. It doesn't need to be a lot. All tiny bits help to improve it.
The next thing i wanted to check was camber. But i don't need to change the model for that, i just need to rotate it a few degrees on the ground and see what it does.
But i chck that with center lines in the wheels, so i can determen the point in a corner and adjust tilt and ackerman.
Under and angle, those things will also change a bit. i want to set a camber of about 10 degrees. A slight camber just to help with centering the wheels.
Only disadvantage of this tilting system is, is that it doesn't walk that great. so lifting the rear wheel and walk with it, will give some problems. But that is for me not a problem. It is more a race trike than anything else.
