Ackermann Steering Geometry The intention of Ackermann geometry
is to avoid the need for tires to slip sideways when following the
path around a curve. The geometrical solution to this is for all
wheels to have their axles arranged as radii of a circle with a
common center point.
Slide 8
Ackermann Steering Geometry Rear wheels are fixed and a center
point must be on a line extended from the rear axle. This line
intersects the axes of the front wheels and requires that the
inside front wheel is turned, when steering, through a greater
angle than the outside wheel.
