Do the front wheels of your car really meet Ackermann's principle when driving through a bend of the road? [PDF]
, 1997 In the past, a trapeziformed four-bar has often been used to realize the unequal turning of these wheels. Geometrically, however, this deviates considerably from the required (relative) motion as dictated by Ackermann's Principle.
