## How is Ackerman angle calculated?

Cot Ф -cot Ө = Where, Ф = Outer wheel steering angle, Ө = Inner wheel steering angle. c = Distance between the pivots of front axle, mm. b = wheelbase, mm. a = Wheel track, mm Consider the Inner wheel steering angle = Ө = 40° (assume) Cot Ф -cot 40 = Ф= 28.5° Turning radius of inner front wheel Rif =

## How do you find the turning angle?

s = wheel base a = steering wheel angle n = steering ratio (e.g. for 16:1, n = 16) r = radius of curvature, in the same units as the wheel base So: r = s / (sqrt(2 – 2 * cos(2*a/n)) For an angle of zero degrees, the radius of curvature is infinite, which is expected.
