A rack and pinion is a pair of gears which convert rotational motion into linear motion. The circular pinion engages teeth on a flat bar - the rack. Rotational motion applied â¦to the pinion (by the steering wheel) will cause the rack to move to one side or the other, right up to the limit of its travel. The rack and pinion arrangement is commonly found in the steering mechanism of cars or other wheeled, steered vehicles.
