How to Steer the Wheel for Fine-Tuning the Car Body?
4 Answers
When fine-tuning the car body, if the front of the car deviates to one side, steer the wheel to the opposite side to straighten it. Only after the direction is straightened, continuing to steer to the other side can change the orientation of the car's front. Below is relevant information about the steering wheel: 1. Introduction to the Steering Wheel: A wheel-shaped device used to control the direction of cars, ships, airplanes, etc. 2. Function of the Steering Wheel: The steering wheel is generally connected to the steering shaft via splines. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Using a larger diameter steering wheel reduces the hand force required by the driver. The steering intermediate shaft, as a connecting component between the steering gear and the steering shaft, facilitates the standardization of the steering gear, compensates for errors during manufacturing and installation, and makes the installation of the steering gear and steering wheel in the vehicle more reasonable.
When I first started driving, I was most afraid of meeting cars on narrow roads. Later, an experienced driver taught me a trick: fine-tuning the steering wheel should be as gentle as holding a soup bowl. For example, if you want the front of the car to lean slightly to the right, gently turn the steering wheel 15 degrees with your right hand, and straighten it as soon as you see the car move. Remember, each adjustment should not exceed the width of the tire. When you see the white line on the roadside move half a finger's width in the rearview mirror, you should stop. Once, while reversing in an alley, I made five such small adjustments in a row, and in the end, the gap on both sides was only two fingers wide without scraping the wall. An old man nearby even gave me a thumbs up.
Last time I was maneuvering in the underground parking lot of a shopping mall with only half a meter of space front and back. I found that fine-tuning the steering wheel required embroidery-like precision: holding the wheel at the 3 and 9 o'clock positions with both hands, giving a gentle 30-degree twist of the wrists, and immediately correcting the direction as soon as the car began to move. The key is to coordinate with the speed—preferably moving at a snail's pace, lightly tapping the brake. This way, you can only move 5-10 cm at a time, but it's extremely precise. Once, I made eight such adjustments and managed to squeeze the car into a tight spot. Even the security guard said my skills were amazing.
Ever seen a watchmaker adjusting clock hands? Fine-tuning the steering wheel is just as delicate. For example, when reversing and noticing the rear of the car is off-center, turn your right wrist about 20 degrees, stopping as soon as you feel resistance in the steering wheel. Never overdo it—judge the car's movement by observing reference points in the rearview mirror, like a utility pole moving half a palm's width before straightening the wheel. When I was a teaching assistant at a driving school, I often used water bottles as obstacles to practice this. Once mastered, parallel parking can be controlled to within 3 cm of the curb.
