The owners who are accustomed to seeing the fault from various indicators，Do you know again，Small steering wheel，Can you judge a lot of failures? today，Xiaobian talks about the steering wheel with a large role in small bodies，What can I judge?

When the vehicle is driving，There is a periodic sound of the chassis，In severe cases, the cab and the door shake，The steering wheel is strongly vibrated，until the hand is numb。This means that the car fails!

Shake on the idle speed

Steering wheel shake is not common when idling，Of course, the amplitude of this jitter is not very large，Generally because of resonance，It has little effect on the use of vehicles，You need to check whether there is a problem with the glue cover of the steering wheel transmission device、Whether the bolt of the transmission device of the fixed steering wheel is loose。

The speed of the car appears at 30 to 40 kilometers per hour

This situation occurs mostly because the tires are rubbed due to daily use、Banging or old causes caused by deformation，Just change the tire at this time。

The speed of the car appears at 80 to 90 kilometers per hour

This situation occurs mostly due to tire deformation or vehicle transmission system。At this time，Should check whether the front wheels and bouquets meet the requirements，If you are in trouble, adjust it，or stand up the front bridge test and rotate the wheel，Check the balance of wheel static and whether the tire is too large，If the deformation is too large, replace it。

Step on the brake jitter at high speed

Excessive brake force、Excessive seabet appfrequency may lead to the brake disc、Her brake pads overheated，Cold deformation，Causes the steering wheel shake。Generally changing the brake disk、After the brake pad，Symptoms can be solved。

Driving normally, low -lying roadsAbnormal

This is due to the car when the car is driving，Polar lever head wear looseness or jams at the joint，It may still be irregular due to wear due to wear，Check the professional maintenance point for professional maintenance，Replace the damage part。

If you find that the car is just started，The first steering wheel is particularly heavy，After that, just fight again，Generally because the driver is in the direction of the driver，There is a valve in the direction machine to open，Makes oil circulation。

As soon as the valve is stuck, there will be a steering wheel sinking situation。But if you always turn to labor，Generally there may be several cases:

Insufficient tire pressure

In particular, pay attention to the front tire pressure，If there is tire pressure monitoring in the car，It is easier to find problems。

Steering system

Steering rolling bearings and sliding bearings in various parts of the direction are too tight，Bearing lubrication bad，Turn to the longitudinal pull rod、The ball head of the horizontal pull rod is too tight or lack of oil，turning shaft and sleeve bending，Card stagnation。

Improper coordination

Improper adjustment of the front wheels, the front sedan or frame bent.

The cause of running bias is large and small，But basically caused by left and right asymmetric。

Left and right tire pressure asymmetry

The simple and simple deal isLeft and right tires are asymmetric,Which side of the tire pressure car is easy to partial。In short,，Check the fetal pressure first if you have any questions，The tire pressure is fine and then deepened。

Suspension components aging wear

Severe more may be the aging and wear of the suspension seabet myparts，Cause caused by different gaps，This situation generally occurs in an old car for more than 8 years，It can be completely solved by replacing parts。

Step on the brakes and run off

If you are not running when you drive normally，Drive when stepping on the brake，And the heavier the steps, the more severe the more severe。This may be caused by the imbalance of braking power to the left and right wheels in the brake system，It is best to monitor the braking system。

steering wheel crooked

The steering wheel is crooked because the positioning parameters are chaotic，Just to offset，The burden at this time is all borne by the wheel。

First see if you step on the brakes,Followed by whether to hit the steering wheel after turning the switch, there will be this sound，If it is not the above situation，Then you need to judge the direction of the sound。

The sound came from under the steering wheel

Check the direction column dust -proof set，Once the direction of the pillar anti -dust cover lacks lubrication, it will produce friction，You only need to paint the sound of butter in the dustproof cover and it will disappear。

The sound comes from the steering wheel

Most of this problem is caused by the interference of airbags in the steering wheel，Remove the steering wheel airbagwater to apply some butter to see it and not sound，If you are still ringing, change the airbags，It may be damaged by airbags。

Pay attention to checking the help system and steering machine

1、Check if there is an oil seepage for the help oil tank，Is there any oil leakage at the pipeline joint。

2. Determine whether the oil is missing in the oil tank after the non -oil seepage.

3. Check whether the hydraulic oil has become dirty and deteriorated.

4. Check whether the pump is damaged.

1、The internal gear of the steering machine is severely worn out，Can't cooperate well，Frication and collision during steering causes abnormal noise。

2. Electronic assistance servo motors fail to change.

3、Available or damage to the sealing ring of the bearing of the internal bearing of the steering machine。

4、Help the motor card，Hold the steering wheel with your hands，The abnormal noise will disappear。
