What does power steering mean?

Power steering refers to the addition of external force to counteract steering resistance, allowing the driver to complete steering with less effort, also known as power-assisted steering. It makes driving simpler and easier, improves vehicle responsiveness, and to some extent enhances safety. There are three types of power steering systems configured in vehicles: mechanical hydraulic power steering system, electro-hydraulic power steering system, and electric power steering system. Economy cars mostly use mechanical hydraulic power steering systems, which generally consist of components such as a hydraulic pump, oil pipes, pressure flow control valve body, V-type drive belt, and oil reservoir.
I remember the steering wheel of my first old car was so heavy that it took sheer brute force to turn, which was exhausting. It wasn't until I switched to a new car that I discovered the wonders of power steering. It's a system that helps you turn the wheel effortlessly, primarily driven by hydraulics or electricity. Sensors detect your turning force, and then a motor or pump provides additional assistance. Without it, parking and making turns become extremely strenuous, especially in the city with frequent steering, leaving your arms sore and numb. Modern cars, like those with electric power steering, are even smarter—light and easy at low speeds, stable at high speeds. I once tried a used car with a failed power steering system, and the steering was so dangerously heavy that I had it fixed immediately. In daily driving, it makes it much easier for female and elderly drivers to control the car, reducing fatigue-related accidents. The key is not to neglect maintenance—regularly check belts and fluids to avoid insufficient power assistance.
