The movement of the steering wheel can be either rotational or translational depending on the situation: when the car is moving straight, the steering wheel moves translationally; when the car is turning, the steering wheel rotates. The working principle of the steering wheel is to transmit torque to the rack and pinion mechanism, thereby pushing the wheels to turn left or right. Solutions for distinguishing left and right on the steering wheel include: 1. The left hand side is the left; 2. The passenger side is the right; 3. The side with gears is the right; 4. The side with the accelerator is the right. The method for removing the steering wheel is: 1. Disconnect all positive and negative battery cables; 2. Remove the lower inspection panel of the steering wheel; 3. Disconnect the connector between the airbag and the spiral cable; 4. Remove the driver's side airbag assembly; 5. Remove the steering wheel nut and take off the steering wheel.

When considering the movement of the steering wheel, it is purely a rotational action. In daily driving, turning the steering wheel makes the car change direction, but the steering wheel itself remains fixed in position on the dashboard without shifting—only the spokes and grips rotate around the central axis. This is similar to turning a knob, where only the angle changes. If it were a translational motion, the steering wheel would slide up and down or left and right, but in vehicle design, this is fundamentally impossible—the structure ensures that rotation is efficiently transmitted to the steering system, reducing driver fatigue. In actual driving, the sharper the turn, the more rotations the steering wheel makes, proving that rotation is key. With translational motion, directional control would become chaotic and could even increase the risk of accidents. Regular maintenance of the steering mechanism also helps prevent issues with rotational smoothness.

As a car enthusiast, I often observe the motion characteristics of the steering wheel: it belongs to pure rotational motion. When you turn the steering wheel, it rotates around its axis, driving the steering column and universal joints, which then control the wheel steering through tie rods. The entire process relies on rotation to transmit torque. Imagine translational motion like pushing a box, but the steering wheel is designed to rotate to improve handling precision; if it were translational, the steering response would be sluggish. Relatedly, modern car power steering systems like Electric Power Steering (EPS) optimize rotational efficiency to make the car more responsive. Understanding this helps in choosing the right components when modifying a steering wheel.

From a physical perspective, the movement of a steering wheel is rotation rather than translation. Translation refers to the overall movement of an object's position (such as sliding a chair), while rotation involves changing angles around a fixed point. The steering wheel is mounted at a stationary position on the car, and when turned, only the angle changes, hence it's rotation. This aligns with everyday experience: turning a car doesn't require pushing or pulling the steering wheel; try moving it without rotation, and the car won't change direction. Simply put, rotation is the core design principle that ensures safe driving.

When driving, steering wheel operation must involve rotation. Turning it steers the car, and fixed-position rotation is the standard procedure; if moved linearly, it becomes ineffective or dangerous. Beginners often make mistakes, such as pushing or pulling the steering wheel, resulting in no steering response from the car, whereas rotation allows precise control over directional changes. Practicing two-handed rotational operation during training can improve reaction speed and prevent sharp-turn accidents. Checking if the power steering system operates smoothly can also prevent rotation difficulties.
