How do you turn the steering wheel? How?
In the process of driving a car, the turning of the steering wheel is crucial. It is not only the main means for the driver to control the direction of the vehicle, but also a key factor in the safety of the vehicle. However, do we really understand how the steering wheel turns? How does it work?
First, the basic structure and principle of the steering wheel.
The steering wheel is an important part of the car manipulator, and its basic structure includes parts such as the disc body, axle, steering knuckle, and wheel hub. When the driver turns the steering wheel, the torque is transmitted to the axle through the disc body, and then finally acts on the wheel through the steering knuckle and the wheel hub, causing the wheel to deflect, so as to realize the steering of the vehicle.
Second, the way the steering wheel is rotated.
Mechanical steering: This method relies mainly on the driver's arm strength and physical strength to turn the steering wheel. When the driver turns the steering wheel, through the meshing of gears and racks, the rack inside the steering gear is moved, so as to push the steering tie rod and the transverse tie rod, so that the wheel is deflected. The advantage of this method is that the structure is simple and the cost is low, but the disadvantage is that the steering torque is large and the operation is laborious.
Hydraulic power steering: This method adds a hydraulic power assist system on the basis of mechanical steering. When the driver turns the steering wheel, the hydraulic power assist system uses the pressure of the oil to amplify the steering torque, making steering more effortless. The advantage of this method is that it is light and responsive, but the disadvantage is that the hydraulic system requires regular maintenance and can not work well in low temperatures.
Electro-hydraulic power steering: This method adds an electronic control system to the hydraulic power steering. When the driver turns the steering wheel, the electronic control system adjusts the pressure and flow of the hydraulic booster system according to the vehicle speed, steering angle and other parameters, making the steering operation more precise and stable. The advantages of this method are high intelligence, fast response and accurate operation, but the disadvantage is that the cost is high.
3. How to realize the rotation of the steering wheel.
Hold the steering wheel correctly: When holding the steering wheel, the driver should adopt the correct holding posture, that is, hold the steering wheel with both hands at 3 o'clock and 9 o'clock, so that the steering of the vehicle can be better controlled.
Turn the steering wheel gently: When turning the steering wheel, the driver should turn gently and avoid excessive force or rapid turning, which can cause the vehicle to lose control or damage components.
Follow the steering principle: When steering, the driver should follow the principle of "left to right", that is, the vehicle turns to the right when hitting the left, and the vehicle turns to the left when hitting the right.
Pay attention to vehicle speed and road conditions: When steering, drivers should pay attention to vehicle speed and road conditions, and avoid sharp turns or sudden braking at high speeds or in bad road conditions to avoid danger.
In short, the rotation of the steering wheel is one of the basic skills of car driving, and mastering the correct rotation mode and implementation method is of great significance to ensure driving safety. Therefore, drivers should always pay attention to their own operation and road conditions when driving a car to ensure that their driving skills are fully utilized and driving safety.
