In our daily driving process, one of the problems that we may encounter frequently, but it does not greatly affect the normal driving, is the incorrect steering wheel. At this time, the so-called four-wheel misalignment occurs. In short, one or more of the four wheels have deviated from the initial position setting, resulting in a deviation.
Before, I personally experienced that the car hit the curb with more force, and then there was a relatively obvious steering wheel error. Later, I went to test and found that the angle of the front wheel was greatly shifted, which was very dangerous, and then I carried out four-wheel alignment.
Four-wheel alignment In fact, some people who understand the principle know that the front wheel alignment is divided intoKingpin caster angle, Kingpin inclination angle, Front wheel camber, Front wheel toe-inthese four parts.rear wheel forCamberand one by onerear toetwo parts.
Several situations are very likely to cause wheel irregularities
1: The front wheel collides with a foreign object
2: Passing through potholes faster
3: The vehicle rubs against the wheel
How to judge the four-wheel irregularity?
1: The vehicle deviates
When the vehicle accelerates, the steering wheel automatically rebounds to the center position. At this time, the vehicle obviously does not go straight and deviates to a certain side.
2: The steering wheel is incorrect
In the normal driving process of the car, the steering wheel is crooked after the automatic rebound, but the driving route of the car is straight.
3: A single tire is severely worn
Normally, the wear degree of the two wheels before and after the car is running should be almost the same. If there is a single wheel with serious wear, it means that the angle is wrong and the wheel is wrong.
What are the dangers of four-wheel misalignment?
Many people don't take the above three issues seriously, because they think that as long as the technology is stable, the car will not be affected, but everyone is unaware of the potential dangers.
1: It is easy to deviate from the lane if you are not careful
Since there are many functions on the vehicle that the driver must operate in person, if there is a distraction for a few seconds during the driving process, if the direction is automatically returned to the right at this time, the vehicle will run off course, which is extremely dangerous.
2: Danger of puncture
The four-wheel misalignment and single wheel eat tire seriously and increase the wear. If it accumulates for a long time, it is very easy to cause the tire wall to become thinner and increase the probability of tire blowout.
3: Poor cornering balance
When the four wheels are out of alignment, if there is a problem with a single support rod and the wheel posture is inclined, then when the car enters a corner, the contact area and direction between the wheel and the ground will be insufficient, the grip is poor, and it is easy to lose control.
4: Accelerate the wear of components such as suspension
Because if the four wheels of a single wheel are out of alignment, long-term abnormal driving will increase the wear of the connecting parts, which will greatly reduce the life of these parts and cause greater safety hazards.
How to deal with it?
If you find the above three points at the first time, it may be a four-wheel misalignment problem, you should go to the nearby repair shop to find a professional for testing. , about 100 yuan.
Summarize:
Most of us are not very concerned about the four-wheel misalignment, but it is really not to be underestimated. I personally experienced a front wheel collision with a single wheel and when the steering wheel was misaligned, I had to keep pulling the steering wheel to drive in a straight line. Accidents will happen, so eliminate all kinds of hidden dangers in time to achieve safe driving.
