I saw a report of the previous incident, and my heart was raw. According to the report, a man in Zhejiang was driving on the road when his steering wheel suddenly locked and he couldn't move at all. As there are electric cars and other vehicles on the road, the driver, out of instinct, stepped on the brake in a hurry, and finally the car stopped. And the owner was scared out of a cold sweat.

What are the reasons for the sudden locking of the steering wheel during driving?

Cause 1: steering machine failure

The official name of steering gear is steering gear, which directly controls the rotation of wheels. The abnormal failure of the steering gear is likely due to the unreasonable design of the water outlet point at the bottom of the vehicle of the front windshield water diversion conduit, and the lax sealing of the steering power mechanism, which results in the sensor harness or internal water inflow, thus leading to the failure of the steering power and the "locking of the steering wheel". If it is caused by this reason, the vehicle may have design defects. Of course, we do not rule out the possibility of such events caused by problems such as steering gear harness.

Reason 2: anti theft function started

In general, when the car stalls, turn the steering wheel to a certain angle, the steering wheel will make a "click" sound, and then it can no longer turn the steering wheel, which is locked at this time. The principle is that there is a pin in the steering wheel. When the key is pulled out, as long as the steering wheel rotates slightly, the pin will pop into the hole and block the steering wheel. In this state, on the one hand, the steering wheel does not turn, on the other hand, the key hole does not turn, so as to ensure that the person with ulterior motives cannot steal your car.

If the anti-theft system fails, it is possible to lock the steering wheel when the vehicle is driving normally.

Then, if the steering wheel suddenly locks when the vehicle is driving, what should be done?

If the steering power disappears and the steering wheel becomes extremely heavy and almost unable to turn without any warning, what the driver has to do is to brake and stop the vehicle in time under the condition of ensuring safety as much as possible. Of course, this process may be violent emergency braking or light braking to stop the vehicle slowly. Measures shall be taken according to the road conditions at that time

Remind all car owners: when using the car everyday, we should strengthen the maintenance of the car and the inspection of important parts. At the same time, when driving on the road, we must also know how to drive the vehicle correctly and treat the vehicle well. In case of an emergency, we should take correct measures to deal with it.
