How Your Car's Steering System Works

The steering system is one of the most vital parts of your car. It translates your rotational indications from the steering wheel into linear motion on the front wheels for turning. While there are various systems in use, the fundamental concept remains the same – to change the position of your car's front wheels as you turn the steering wheel. This makes it easy to maneuver your vehicle and provides a safe driving experience. However, this system can easily become faulty or worn over time if not properly maintained and serviced. That's why it's important to know how your steering system works, its basic function, and the various types of steering systems used in vehicles.

The most common system in use today is the rack and pinion system. In this type of system, a shaft extends from the steering column and has a round gear at its end called a pinion. The pinion interlocks with straight rows of teeth on a notched bar called a rack. Rotating the pinion gear moves the rack to shift its ends left or right, causing your car's front wheels to turn. This type of steering system is used in cars and most smaller trucks, but is not usually found on semi-trucks.

Another popular steering system is the recirculating ball system. In this system, there is a large block with threads on which the steering wheel is attached. The steering wheel's worm gear then meshes with the sector gear on this block, and changing the direction of the wheel rotates the worm gear, which in turn changes the direction of the sectors on the recirculating ball. The recirculating ball then relays this movement to the pitman arm, which in turn connects with either the left or the right tie rod end. The pitman arm then relays the movement to the steering knuckles, which in turn move the wheels.

While recirculating ball systems are more complex than the rack-and-pinion design, they are also less likely to wear out or break. They can be found in older vehicles, including some British sports cars of the 1950s. However, this type of steering system is slowly being replaced by rack-and-pinion systems, as they are more efficient, easy to maintain, and provide precise control over the vehicle's direction.
