RACK AND PINION STEERING
Rack and pinion steering provides a much simpler method of converting the circular motion of the steering wheel to linear motion for steering. The steering column attaches to the top of the rack and pinion unit and rotates the pinion gear. The pinion gear actuates the rack, which is a simple straight shaft with teeth cut in the top. The rack will simply move back and forth, in a linear motion, in response to the pinion gear. The only steering linkage used is tie rods to indirectly link the rack gear to the steering knuckle. Vehicles with power rack and pinion steering use hydraulic pressure to assist in rotating the pinion gear.
