When should I turn the steering wheel when driving left and right?

How to turn the steering wheel and how much depends on the actual road conditions:

1. Turning curvature:

The steering wheel should be hit according to the bending degree sooner or later. If the curve is big, you need to hit it early, but the speed is slow. If it is sharp, it needs to be played later, but the speed should be fast. Don't wait for the front of the car to straighten after turning the corner, wait for the front of the car to come back soon.

2. Pavement width:

If it is a left turn, turn the steering wheel when the right corner of the front of the car is tangent to the roadside in the case of narrow road surface, and turn the steering wheel earlier in the case of wide road surface. So is turning right. Remember to adjust flexibly and adjust the steering wheel according to the specific driving trajectory of the vehicle.

3. Steering principle:

(1), slow bend (early play, slow play; Early return, slow return), sharp bend (late play, fast play; Come back early.

(2) Pay attention to the right side when turning, don't scrape or drive the rear wheel off the road, and pay attention to the inner wheel difference.

(3) If there are obstacles on the roadside, start to hit the direction when people and obstacles are almost parallel.

Extended data:

The steering wheel is generally connected with the steering shaft through splines, and its function is to convert the force that the driver acts on the edge of the steering wheel into torque, and then transmit it to the steering shaft. When steering with a steering wheel with a larger diameter, the driver's hand force acting on the steering wheel is smaller. As the connecting piece between the steering gear and the steering shaft, the steering transmission shaft is beneficial to the generalization of the steering gear, compensates the errors in the manufacturing and installation process, and makes the installation of the steering gear and the steering wheel more reasonable.

Steering wheel composition:

1, skeleton, usually zinc alloy, or aluminum alloy, some manufacturers are trying to use cheaper and lighter magnesium alloy. The skeleton is produced by die casting. A few manufacturers still use steel plate metal as the skeleton, and the structure is complicated.

2, foaming, foaming materials are produced in a foaming machine, and the skeleton is fixed in the foaming machine during production.

3. Some steering wheels need skin sewing, which is generally done by workers in China.

4. Some steering wheels need wood. Use a special machine to stack the wood chips layer by layer and finally paint them.

5. Some steering wheel wood is replaced by fake wood, which is usually finished by plastic injection molding such as PP and ABS, plus watermark.

6. There will be a mounting buckle or screw hole corresponding to the main driving airbag DAB on the steering wheel.

7. Some steering wheels need horn contacts. An easier method is to press the horn contact into the frame. Another method is to make a horn contact module and integrate a part of electrical wiring harness and circuit board on it.

8. Some steering wheels need switches, which are mainly located on both sides of the spoke shell or the main airbag. Their functions are generally radio, acceleration and deceleration, cruise, sound, telephone answering and so on. The steering wheel should provide not only the mounting buckle, but also the harness interface.

9. Generally, there will be a multi-function switch module or paddle shift under the steering wheel. At this time, it is necessary to consider the electrical connection.
