What are the three main components of a mechanical steering system?

Automotive steering systems generally consist of three main components: the steering control mechanism, the steering gear, and the steering linkage. When the steering wheel is turned, the steering shaft and worm gear rotate, causing the steering arm to swing and push the drag link back and forth. Since the steering knuckle pivots around the steering axis, it turns one of the front wheels to achieve vehicle steering control. Below is relevant information about steering systems: 1. There are two types of steering systems: mechanical steering systems, where the steering power comes from the driver's physical effort; and power steering systems, where the steering power includes both the driver's effort and the engine's power, typically used in vehicles weighing over 50 tons. 2. The requirements for steering systems include: the ability to self-center, light and responsive operation, consistency between steering direction and vehicle movement, minimized kickback to the steering wheel, and no self-oscillation during driving.
The mechanical steering system is primarily divided into three major components, each crucial for handling. The steering control mechanism is the starting point of the entire system, essentially the part driven by the steering wheel, including the steering column and some connecting parts—it responds as soon as you turn the wheel while driving. The steering gear is the core, tasked with converting the rotational motion of the steering wheel into linear push-pull movement, such as via a steering gear or rack; if the steering gear wears out, the wheel becomes heavy and unresponsive, compromising driving safety. The steering linkage, composed of components like tie rods and steering knuckle arms, transmits force to the wheels to enable turning; looseness or aging here can cause wheel wobble. As an experienced mechanic, I've seen many accidents stem from neglected maintenance of these parts, so I advise drivers to regularly inspect the steering system, lubricate key points, and ensure free play stays within safe limits.
As a car enthusiast, the structure of mechanical steering systems is truly fascinating, consisting of three basic components. First is the steering control mechanism, where the steering wheel and shaft assembly allow you to input commands to rotate the system. Second is the steering gear, which acts as a converter, transforming rotational motion into linear push-pull forces through mechanisms like the steering worm or recirculating ball system; failure of the steering gear can lead to sluggish steering or unusual noises. Third is the steering linkage, which includes the tie rod arms and steering knuckles connected to the wheels, directly driving changes in steering angle. A common issue when driving older cars is instability in steering caused by worn tie rod ends, posing significant safety risks. I always emphasize checking the integrity of these components and applying grease to maintain flexibility—don't wait until losing control to regret it.
