Ackermann geometry. The Ackermann steering geometry (also called Ackermann's steering trapezium) [1] is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
A tire can generate horizontal force where it meets the road surface by the mechanism of slip. That force is represented in the diagram by the vector F. Note that in this example, F is perpendicular to the plane of the tire. That is because the tire is rolling freely, with no torque applied to it by the vehicle's brakes or drive train. However ...
where is the force on the front tires, is the force on the rear tires, is the distance from the CM to the rear wheels, is the distance from the CM to the front wheels, is the wheelbase, is the mass of the vehicle, is the acceleration of gravity (approx. 9.8 m/s 2), is the height of the CM above the ground, is the acceleration (or deceleration ...
Its hubless wheels are made from former truck tires, and a chain-driven friction drum provides power and brake force. [6] Designed "for casual cruising and slow ride-bys at shows", it consists of a 996 cc (60.8 cu in) fuel-injected Suzuki 4-stroke engine [7] in a steel frame covered by a fiberglass body with electroluminescent wire lighting.

In this case the lateral forces at the tire do not act at the center of the contact patch, but at a point behind the center. This distance is called the pneumatic trail and varies with speed, load, steer angle, surface, tire type, tire pressure and time. A good starting point for this is 30 mm behind the center of the contact patch. [citation ...
Geometric roll center is solely dictated by the suspension geometry, and can be found using principles of the instant center of rotation.; Force based roll center, according to the US Society of Automotive Engineers, is "The point in the transverse vertical plane through any pair of wheel centers at which lateral forces may be applied to the sprung mass without producing suspension roll".

Performance vehicles may run zero front toe or even some toe-out for a better response to steering inputs. Increased front toe-in marginally increases the wear on the tires as the tires are under slight side slip conditions when the steering is set straight ahead. On front-wheel drive vehicles, the situation is more complex. Rear toe-in ...
