What Are the Different Parts of a Steering System?

The steering system is made up of three major parts: the steering box, the suspension parts and the steering linkage. The steering box connects to the steering wheel, the suspension parts pivot the wheel assembly, and the steering linkage connects the steering wheel to the front wheels.

The primary function of the steering box is to ease the task of making a turn. There are two models of steering box, one with rack-and-pinion gearing and one with worm gears. A worm gear is a threaded cylinder that resembles a small bolt, while a rack-and-pinion is a little gear wheel that runs on a long transverse bar

The primary function of the steering linkage is to translate movement to the front wheels. Steer-by-wire systems, which are recent technology as of 2015, have replaced the steering linkage in some vehicles, but most modern vehicles still use steering linkages.

Suspension parts include the shock absorber system and the ties that join a vehicle to its wheels. There are two core functions of the suspension system: to allow the wheels to grip and maintain contact with the road and to ensure passengers travel comfortably by reducing the effects of bumps, road noises and vibrations.
