What is the reason for the rattling sound in the direction of the car?

There are a lot of gurgling sounds on the left and right steering wheels, and the first thing to distinguish is the part: 1The lower part of the steering wheel may be caused by loose bolts or a lack of lubricating oil.

2.The chassis part of the body, mainly the suspension parts with too large axle head clearance or loose bolts, need to be checked. One.

Basic Concept 1A wheel-shaped device used to control the direction of travel for automobiles, ships, airplanes, etc. In the fifties, concept cars without steering wheels were introduced, but consumers were not interested in them at all.

Because a car without a steering wheel is not a car at all. 2.The first cars were controlled and driven with rudders.

The rudder cannot be said to be bad, but it will transmit the violent vibrations generated by the car to the driver, making it more difficult for him to control the direction. When the engine was relocated to the front of the car, the driver could no longer use the rudder to drive the car due to the increased weight. 3.

But the original designer of the steering wheel could not have foreseen that in today's faster and faster cars, once a car accident occurs, the steering wheel will become a driving test failure.

There is a certain relationship between the abnormal sound of the steering wheel and the change of temperature, and it may be that the steering column is faulty, the plastic will become hard after the temperature drops, and there will be abnormal noise when the steering wheel is played, and there will be friction when the gap is small when turning, and the run-in can be returned to normal after a period of time, depending on the situation.

If the abnormal sound of the steering wheel is a normal phenomenon in winter, because the plastic parts on the steering wheel produce friction, resulting in the gap of the car when it rotates, this fault does not need to be dealt with, and the normal use can be resumed when the weather warms up, if it is abnormal noise during the run-in period, it is normal to resume normal use after the run-in period, and if there is abnormal noise after the run-in period, the steering wheel needs to be reinstalled.

First of all, it is necessary to distinguish between normal and abnormal sounds. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises really had problems. Models equipped with turbocharged engines are different; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that due to their lack of understanding of mechanical knowledge, they mistake reasonable abnormal noise as a vehicle failure.

Therefore, learn to distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to measure the sound of the car with special instruments, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will emit a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal noise. The normal vibration sound of each system component (such as the noise on the surface of the engine), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of wear of the parts is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal operation of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire cut-off to reduce the sound to meet the diagnostic needs. The auscultation site should be kept quiet to minimize human interference.

Generally, it is the problem of the general column under the steering machine, and it will be fine if you change it. I changed the car in 14 years. Generally, there will be a sound when you hit the dead back direction.

1. This situation generally appears in the model of mechanical hydraulic power steering, which is a very common way of steering power in the past, referred to as HPS in English, with mature and reliable technology and low cost. This type of steering power assist converts a part of the engine's power output into hydraulic pump pressure, which exerts auxiliary force on the steering system to steer the tires. When the steering wheel is not turned, the pressure in the chambers on both sides of the piston is the same and it is in equilibrium.

When the steering wheel rotates, the mechanical control valve connected to the steering column will be opened or closed accordingly, one side of the oil will no longer pass through the hydraulic cylinder and directly flow back to the oil storage tank, the other side of the oil continues to be injected into the hydraulic cylinder, the pressure difference between the two sides of the piston will be pushed under the action of the hydraulic force, and then produce auxiliary force, at this time we will feel that the steering wheel is not so laborious.

2. The steering pump drives the belt to slip. The steering pump is driven by a belt, and if the friction between the belt and the pulley is too small, the belt will slip on the pulley, and there will be a squeaky sound at this time. It may be caused by loose belt adjustment, excessive wear of the grooves of the pulley, or the new belt does not fit well with the old pulley.

A simple way to tell is to pour a little water on the belt when there is a noise, if the noise goes away, it means that the belt is slipping. At this time, first adjust the tension of the belt, if there is still a sound after adjustment, you can use it for a period of time to make the belt and the pulley fully match and then see if it is still ringing, if it is still ringing, you have to replace the pulley.

What to do if the steering wheel of the car is abnormal.

1. The sound of rebounding the clip after the turn signal.

2. The sound of the dust jacket of the direction column.

Whether you are in place or driving as long as you hit the steering wheel, you will hear the sound coming from under the steering wheel, you must check the steering post dust jacket, once the steering post dust jacket lacks lubrication, it will produce a dry friction sound, you just need to apply some butter in the dust jacket This sound will disappear.

Hello, it may be the reason for the ball head or the steering machine, and it is recommended to go to the after-sales maintenance station for inspection.

Reasons why a car rattles in the direction are: the sound of the turn signal, a problem with the steering wheel, damage to the inside of the spiral cable, or a lack of lubrication.

1. The sound of the turn signal: If the turn signal is played at the same time when turning, the sound may be the sound of the rebound clip of the turn signal automatic return mechanism. If you hit the steering wheel after hitting the turn switch, it will have this sound, which is the sound of the rebound card of the turn signal automatic return mechanism, and this sound is normal.

Solution: You need to turn off the turn signal.

2. There is a problem with the steering wheel: If the abnormal noise comes from the steering wheel, the problem is likely to be caused by the airbag hairspring in the steering wheel.

Solution: Remove the steering wheel airbag hairspring, apply butter and see if it still rings.

3. Damage or lack of lubrication inside the spiral cable: It is usually caused by damage or lack of lubrication inside the spiral cable.

Solution: If it is confirmed that it is an internal fault of the spiral cable, it can only be replaced, and the finger cannot be repaired by yourself.

The cause of abnormal steering wheel noise and how to deal with it

1. The ball head of the steering tie rod is aging. Replace the ball head of the steering lever and perform four-wheel alignment.

2. Oil leakage from the steering gear dust cover. Replace the dust cover or refill the butter.

3. Steering gear failure. This may be due to the large gap between the steering gear and the gear, which is causing the steering to be replaced.

In addition, if you hear an unusual sound from outside the car when you open the steering wheel, it may be due to a lack of oil in the flat bearings of the shock absorber. Just open the hood and listen to the sound. It doesn't come out of the top seat position of the shock absorber.

In general, the ** of the sound can be determined. When the flat bearing of the shock absorber makes an abnormal sound, you can apply some butter to the flat bearing. If there is an abnormal noise after application, it can only be replaced.

A variety of reasons are as follows:1. The sound of the vehicle's turn signal.

2. The sound that appears inside the steering wheel.

3. The sound of the dust jacket of the steering system.

4. The abnormal sound emitted by the steering machine.

5. The sound of the steering gimbal near the accelerator and brake pedal. All of the above causes are:

There was a loud bang in the direction of the car. There are many reasons for this. 1.

The steering power of automobiles is generally divided into electronic steering power and hydraulic steering power. If it's hydraulic power steering, it's normal to hit the steering wheel with a hammer. Because when the steering wheel is killed, the hydraulic booster pump is under high load, and abnormal noise will occur in this case.

2.The sound of the turn signal returning. For example, when the left turn signal is turned on and the steering wheel turns to the right, the turn signal automatically returns, accompanied by a banging sound, which is the rebound clip of the turn signal automatic return mechanism that makes a gesture sound, normal.

3.The clearance between the axle heads of the suspension parts is too large or the bolts are loose. If this is the case, the abnormal noise usually comes from the chassis or the steering column under the steering wheel.

Workaround: Adjust to normal clearance. 4.

There is a problem with the ball joint. The function of the ball head is to make the steering mechanism rotate smoothly and reduce vibration. If there is a problem with the ball head, there will naturally be a heavy hitting sound.

Solution: Replace the ball joint. Others, such as airbag hairsprings in the steering wheel, balance bars, etc., can cause abnormal noise.

A professional examination is required to know what the problem is.
