Ackermann geometry. The Ackermann steering geometry 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.
Ackermann steering geometry. The basic aim of steering is to ensure that the wheels are pointing in the desired direction to move the vehicle as required. This is typically achieved by a series of linkages, rods, pivots, and gears. One of the fundamental concepts is that of caster angle. Each wheel is steered with a pivot point ahead of the ...
Caster displacement moves the steering axis ahead of the axis of wheel rotation, as with the front wheels of a shopping cart. Caster angle moves the steering axis from vertical. [3] In automobile racing, the caster angle may be adjusted to optimize handling characteristics for a particular venue. This is all connected to the front wheels.
One related concept is that the proper toe for straight-line travel of a vehicle will not be correct while turning, since the inside wheel must travel around a smaller radius than the outside wheel; to compensate for this, the steering linkage typically conforms more or less to Ackermann steering geometry, modified to suit the characteristics ...
Dual-pivot steering geometry (also known as virtual pivot) is a geometric arrangement of linkages in the steering of a car designed to reduce or eliminate scrub radius by moving the pivot point of the king pin outboard, in order to improve steering precision and straight line stability.
When a steering quickener is employed in an automobile, the driver of the automobile can turn the steering wheel a smaller degree compared to a factory-installed steering system without a steering quickener, to turn the vehicle through same distance. [2] On the other hand, the steering effort needed will greatly increase.
The advantage of a small scrub radius is that the steering becomes less sensitive to braking inputs. More scrub radius adds to road feel by pushing the inside wheel into the ground. An advantage of a negative scrub radius is that the geometry naturally compensates for split μ (mu) braking, or failure in one of the brake circuits. It also ...
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.
