What is the Function of a Car Steering Wheel?
2 Answers
The function of a car steering wheel is to convert force into torque and transmit it to the steering shaft. The steering wheel, also known as the driving wheel, is a wheel-shaped device used to control the direction of vehicles such as cars, construction machinery, and agricultural vehicles. The hub, rim, and spokes of the steering wheel are typically made with an inner core of steel, aluminum alloy, magnesium alloy, or carbon fiber. The steering wheel is usually connected to the steering shaft via splines. As a general rule, avoid turning the steering wheel forcefully while the vehicle is stationary, commonly referred to as 'locking' the steering. When the wheels are not rolling, the friction between the tires and the ground is significantly higher, placing greater stress on the steering mechanism. Turning the steering wheel while stationary not only risks damaging the steering mechanism but can also cause severe tire wear.
On my daily commute, the steering wheel is like my right-hand man. Turning it allows me to effortlessly control the car's direction, avoiding traffic jams or changing lanes. I remember once on the highway when I almost hit an obstacle, a slight twist of the steering wheel helped me dodge it—so convenient! It also integrates many functions, like the heating feature in my car's steering wheel, which keeps my hands from freezing in winter. Additionally, the power steering system makes turning even lighter, so even women can handle it with ease. However, it's worth noting that the feel of the steering wheel varies by car model—leather ones are more comfortable, while plastic ones can be a bit slippery. I’ve also heard that early car steering wheels were very heavy, unlike today’s electronic power steering, which makes long drives less tiring. Don’t forget to regularly check if the steering wheel is loose—safety first!
