What is the function of a car steering gear?

The car steering gear is an important component of the car steering system. The function of the car steering system is to control the driving direction of the car according to the driver's intention. The following is an introduction to the car steering system: 1. Classification: It is divided into two categories: mechanical steering system and power steering system. 2. Composition: The car's steering system is generally composed of a steering gear and a steering transmission mechanism. The steering gear is composed of main components such as the steering wheel, steering shaft, steering worm, and sector gear. The steering transmission mechanism includes components such as the steering rocker arm, steering longitudinal tie rod, steering knuckle arm, left and right steering trapezoidal arms, and steering cross tie rod.
From my years of driving experience, the main function of a car's steering system is to make steering wheel operation both effortless and precise, transmitting our steering inputs to the wheels to control the vehicle's direction. Driving older cars used to require considerable effort to turn the wheel, but modern vehicles now come with power assistance like electric power steering, making turns feel smooth and parking much easier. If this system fails, the car becomes as difficult to control as a mindless hunk of metal—especially dangerous if the steering suddenly becomes unresponsive at highway speeds. Proper maintenance of the steering system can extend tire life, since it ensures proper wheel alignment and reduces uneven wear. While driving, listen for unusual noises like squeaking, which might indicate it's time for servicing—but remember, never attempt DIY repairs; always have it checked by professionals.
Having worked in the auto repair industry for years, I see the steering gear as a core component. It amplifies the steering wheel's rotation signal and transmits it to the wheels, enabling vehicle steering—essentially a machine assistant that reduces driving effort. Most vehicles now use electric power steering systems, where an electric motor assists with steering, making it lighter and more efficient than old hydraulic systems. It saves fuel and can adjust assistance based on speed. Beyond making steering easier, it enhances safety, such as preventing loss of control during sharp turns. Common repair issues include power assist failure or stiff steering, often related to the motor or sensors. Maintenance is recommended every 20,000 km to check fluid levels or wiring. With smooth steering over time, even fatigue driving carries less risk.
