The free rotation is intended to help make steering with one hand easier or faster. Some heavy automobiles without a power steering system tended to have heavy and slow responses requiring hand-over-hand turning of the wheel by the driver, and the knob allowed the driver to "crank" the steering wheel to make faster turns.

A steering ratio of x:y means that a turn of the steering wheel x degree(s) causes the wheel(s) to turn y degree(s). In most passenger cars , the ratio is between 12:1 and 20:1. For example, if one and a half turns of the steering wheel, 540 degrees, causes the inner & outer wheel to turn 35 and 30 degrees respectively, due to Ackermann ...
The point where the steering axis line contacts the road is the fulcrum pivot point on which the tire is turned. Scrub radius is changed whenever there is a change in wheel offset. For example, when the wheels are pushed out from the body of the car the scrub radius becomes more positive.
Sensors collect data such as current vehicle speed, turning angle, terrain conditions, crosswind acceleration, and torque applied to the steering wheel. [ 5 ] [ 6 ] [ 7 ] The electric motor is a device powered by electricity that adds torque in the form of mechanical energy to a steering gear(the gear responsible for translating the rotation of ...
A steering wheel (also called a driving wheel, a hand wheel, or simply wheel) is a type of steering control in vehicles. Steering wheels are used in most modern land vehicles, including all mass-production automobiles , buses, light and heavy trucks, as well as tractors and tanks .
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.
Torque steer is the unintended influence of engine torque on the steering, especially in front-wheel-drive vehicles. For example, during heavy acceleration, the steering may pull to one side, which may be disturbing to the driver.
The recirculating ball steering mechanism contains a worm gear inside a block with a threaded hole in it; this block has gear teeth cut into the outside to engage the sector shaft (also called a sector gear) which moves the Pitman arm. The steering wheel connects to a shaft, which rotates the worm gear inside of the block.
