Simple approximation for designing Ackermann geometry. A simple approximation to perfect Ackermann steering geometry may be generated by moving the steering pivot points [clarification needed] inward so as to lie on a line drawn between the steering kingpins, which is the pivot point, and the centre of the rear axle. [3]
The steering linkages connecting the steering box and the wheels usually conform to a variation of Ackermann steering geometry, to account for the fact that in a turn, the inner wheel travels in a path of smaller radius than the outer wheel, so that the degree of toe suitable for driving in a straight path is not suitable for turns.
A series of more advanced designs were introduced, especially through World War II, that maintained power to both tracks during steering, a concept known as regenerative steering. Some also allowed one track to move forward while the other reversed, allowing the tank to spin in place, a concept known as neutral steering .
The Understeer Angle is the amount of additional steering (at the road wheels, not the hand wheel) that must be added in any given steady-state maneuver beyond the Ackermann steer angle. The Ackermann Steer Angle is the steer angle at which the vehicle would travel about a curve when there is no lateral acceleration required (at negligibly low ...
The steering kingpin is held in place by the forked ends of a beam axle on a Ford Model T. The kingpin (also king-pin, king pin and k pin) [1] [2] is the main pivot in the steering mechanism of a car or other vehicle. The term is also used to refer to part of a fifth wheel coupling apparatus for a semi and its trailer or other load.
No, you should not use 100% Ackermann for a high speed car. Typically a modern production car will use perhaps 60% Ackermann, whereas racing cars often use parallel steer (0% Ackermann), or even negative Ackermann, in which the outer wheel turns more than the inner wheel.

As I understand from your explaination, the image I made is correct, but the text/article isn't. So obviously the image needs to be placed at Ackermann steering (yet perhaps the name needs changing too to Ackermann steering linkage). You also hint that parallellogram steering does exist, but the explaination doesn't match what it exactly is.
Pitman arm Steering box, with the pitman arm just visible beneath. A Pitman arm is a shaft that translates rotary or angular movement into linear movement, or vice versa. Pitman arms are commonly found in water pumping windmills, automotive steering systems, and sewing machines. In windmills, the Pitman arm connects the driving gear to the ...
