How to solve the abnormal noise of the steering wheel and the abnormal noise of the brakes

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 should 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.

Abnormal steering wheel noise: Basically, it is normal to turn the steering wheel after the engine is turned off, but it is not recommended that the vehicle rotate the steering wheel on the spot, as playing the direction in place will cause wear and tear on the tires, steering system and shock absorbers. When the vehicle starts, there is an abnormal sound in the direction of rotation may be the noise of the shock absorber pressure bearing, it is recommended that you go to the 4S shop to re-check the pressure bearing.

The damage of the pressure bearing is mainly related to driving habits, and the following points should be paid special attention to in future driving. 1. Avoid turning the steering wheel on the spot, and try to play the direction after the vehicle moves. 2. When the vehicle is stopped, the steering wheel should be returned to the center position to avoid excessive load on the suspension parts and tires.

3. When you need to turn around, try to avoid the steering wheel hitting the dead center, if you need to hit the dead center, but the time should not exceed 5 seconds.

1. The steering string is not lubricated and has high friction.

2. Check that the steering power oil is less.

3. Check whether there is a problem with the universal joint.

4. The chassis suspension balance rod lifting lug sleeve is aging and hardening.

5. The plane bearing is broken.

Causes and solutions to abnormal steering wheel noise:

1. The ball joint of the steering tie rod is aging and has an open space. Replace the steering tie rod ball joint and do four-wheel alignment.

2. Oil leakage from the dust jacket of the steering machine. Replace the dust jacket or re-butter it.

3. Steering machine failure. It may be caused by the gear clearance of the steering machine is too large, and the steering machine needs to be replaced.

4. If the tightness of the booster belt is improper or aging, the tightness of the belt needs to be adjusted or replaced.

Stepping on the brakes on the spot to hit the direction is the ape-man way! If you were born 30 years early, you may not even be able to get a driver's license. Anyone who has gone to junior high school and learned physics knows that the rolling grinding coefficient is the smallest, and the direction of the restoring is played?

Before the friction of the ground of the front wheel without the steering power device, the torque sound of the second pull rod, and the friction of the ball sleeve of the third ball head, as you said, this phenomenon is generally the damage of the pressure bearing on the shock absorption, or the abnormal sound caused by the damage of the ball head of the low disc arm and the lack of oil, and you have to go to the repair shop 4S shop to check.

<>If you don't have one, you have to check the cage, it must be a problem with the cage, and if it is from the car, you have to check whether the airbag balance spring under the steering wheel and the cross joint inside the direction column are normal. These two parts are worn or faulty, there will be you Hello, I am doing automobile after-sales maintenance services, your situation should be a problem with the pressure bearing or top rubber on the shock absorption, the solution is to disassemble the shock absorber, and replace it with a new pressure bearing or top rubber. Cause of failure:

This phenomenon occurs when one of the wheel bearings of a vehicle is damaged. Long-distance driving has high requirements for the bearing of the wheel, and the bearing will be damaged due to fatigue damage due to fatigue under the long-term high-speed operation of the bearing, which is not of good quality or has been used for a long time.

Check steps: 1. Whether the tire is caught with stones; 2. Plane pressure bearing (if the sound is happening here); 3. a steering tie rod ball joint; 4. a balance rod tie rod ball joint; 5. Front wheel vertical shaft ball joint. Step by step, the basic plane bearing is likely to be damaged.

This will also happen to the travel problems of various parts of the suspension shock absorber, when the ball joint of the tie rod is loose or the front swing arm is deformed back and the steering wheel shakes back and forth when the driving is idling, it can be checked and replaced. My habit is: if the car wants to pull over, first hit the right turn signal, look in the rearview mirror to see if there is a vehicle in the right lane, if not, press the clutch and brake pedal, and gradually reduce to the low gear, stop to the side of the road and hang neutral, pull down the hand brake.

When you press the brakes on the spot and hit the direction, the wheels rub against the ground to make a sound of rattling tires. The steering system vibrates due to increased force on the steering system, and a gurgling sound is emitted. The suspension system is also stressed, but it is easy not to make noise, unless some cars with a problem with the suspension system may make a rattling or creaking sound.

Of course, it doesn't mean that you can't step on the brakes in place to play the direction, after all, in some cases, you really need to step on the brakes in a narrow space, so we don't have to be completely taboo, try to avoid it when allowed, you really need to step on the brakes to play the direction on the spot, you don't have to step on the brakes, and you can limit the movement of the vehicle by tapping the brakes.

I don't think you should drive anymore in this case. You can send the car to the maintenance office for maintenance and solve the problem in time.

I think that this situation can be solved by changing the brake pads and steering power oil. It is necessary to repair it in time, otherwise it will lead to safety hazards.

When the wheel rubs against the ground when the brake is pressed, the tire rattles sound, and the steering system vibrates when the force increases, and the steering system vibrates. In the final analysis, it is the steering structure of the car that determines the sound that occurs when you press the brakes on the spot.

When the car is in place, the steering wheel does not rotate around the center of the tire, but rolls slightly, because the center of rotation of the tire is not in the geometric center of the tire, but in the center of rotation of the knuckle. When playing in the same direction, the wheel actually rolls in a circle with the steering knuckle axis as the center of the circle. At this time, we step on the brake to play the direction, which will inevitably hinder the wheel rolling, resulting in the sound of the wheel rubbing against the ground, and at the same time, it will also drive the relative motion trend of the friction block and the brake disc, and produce the creeping sound of the brake friction block and the brake disc.

It is not recommended to operate this way for a long time, as it will increase the burden on the steering mechanism, brakes and suspension. Of course, this is not to say that you can't step on the brakes to play the direction on the spot, after all, there are some situations where you do need to step on the brakes to turn around in a narrow space, so we don't have to be completely taboo. Try to avoid it if you can, if you really need to step on the brake to hit the direction on the spot, you don't have to step on it, and just tap the brake to restrict the movement of the vehicle.

Abnormal braking noise, which is basically the case of automatic transmission cars. The friction sound of the brakes and clutches not leaving will be improved when the brake pads are sharpened again. Done, mobile phone typing is hard, if it is helpful to you, please click on the reply below, thank you.

The brake squeaks, the vehicle brakes at low speed, at this time, the brake pad surface and the brake disc friction will appear hardened layer, in the brake disc or brake drum surface of this hardened layer in the case of cold car is easy to scream, if you want to eliminate the abnormal noise, check the brake noise of the part that causes the brake noise There are many reasons, such as the brake disc is uneven, the brake pad is too hard, there are foreign objects between the brake pad and the brake disc, etc., which will cause the brake to have abnormal noise. We need to solve this according to the actual choice. If the brake disc is uneven, it needs to be replaced or repaired.

If they are just simple brake pads, when stepping on the brakes produce abnormal noise, at this time we can check, whether the brake pads are too thin, has rubbed to the alarm on the brake pads, when our brake pads are too thin, once we step on the brakes, we have to say that if we can drive, but not necessarily understand the car, because now for the understanding of the car, in fact, many people are ignorant of it, So, for example, what kind of speed should we use when driving, or whether we should apply the brakes when turning.

Just pay attention to the timely replacement. However, after this "squeak" disappears, the brake pads must be replaced, because the metal plates may have been damaged, and in this case, it is necessary to pay attention to check whether the brake discs have been worn out when replacing the brake pads. The first reason may be relatively rare, drive the car to the repair shop, and let the master see if the brake pads are worn to the point of touching the disc?

Let's take a look at the brake cylinder return to position! Add the new brake pads, maybe because there are too many metal particles, rubbing the sound of the disc!

First of all, if there is only a squeaky sound, you can only replace the brake pads. If there is directional jitter, you need to check the brake disc. After the brake pad is used to a certain thickness, it will trigger a spring metal sheet, and then step on the brake at the same time to produce a squeaky metal friction sound, which is to replace the brake pad, if the replacement is not timely will wear the brake disc, the cost of repairing the car will be high, put the direction in one direction to the head to observe the brake pad you will see.

Don't drive anymore at this time. The car should be driven to the 4S shop in time for a test, so that it can be effectively repaired.

Immediately stop the power, stop stepping on the accelerator, reduce the amount of oil, immediately get out of the car to check if it is an engine failure, if you can't find the cause, go to the 4S shop for maintenance.

The brake pads need to be replaced, and if the edges are not very deep, they can be solved by sanding the edge of the brake disc.

Abnormal brake noise indicates that the steering wheel is faulty, and the brake pads should be checked to see if they are worn too much.

The reasons for the abnormal sound of stepping on the brake and hitting the steering wheel are as follows: 1. The disc brake makes an abnormal sound. Features:

When the vehicle is driving on a flat road at a low speed, it makes an intermittent and irregular noise at the wheel axle part, and the sound will be slightly aggravated when the speed increases, but there is no change when going uphill and downhill and turning; When driving on uneven roads, the noise is aggravated, and the sound of pressing the brake pedal with your foot is reduced or eliminated. 2. Due to the damage, deformation and falling off of the brake shoe support plate, damping spring plate or guide plate of the disc brake, the gap between the brake shoe and the brake caliper support frame increases, and the sound is made when it hits each other. You can go to a repair shop to repair deformed parts and replace the parts that have fallen off.

3. The abnormal sound of the ball head hanging before Sun La. When the vehicle is driving on the undulating road surface in a low-speed gear, the front axle part emits an uninterrupted abnormal sound, the worse the road quality, the louder the sound, the sound intensifies with the increase of speed, and the front of the vehicle will be abnormal after stopping. Because the ball head seat is a sealed structure, it cannot be removed and can only be replaced.

Summary. The rattling sound in the direction of the brake is due to a problem with the ball head or arm of the chassis. Generally speaking, there is an open space in the plane of the brake disc, and when the car applies the brakes at high speed, the brake pedal will have a slight jump, and this beating will also be transmitted to the steering wheel through the relevant steering system, causing the steering wheel to shake left and right.

Once the brake disc has been sanded, it can be reused.

Sometimes it will also make the booster pump the highest pressure, producing a sound Do you have any other questions that I need to answer for you?

There is a rattling sound in the direction of the brakes.

Hello, Nianzi your problem I have seen Ha Now I am hand-hungry for you to return to the limb content, but it takes a little time, please wait patiently, thank you

The rattling sound in the direction of the brake is due to a problem with the ball head or arm of the chassis. Generally speaking, there is an open space in the plane of the brake disc, and when the car steps on the brakes at high speed, the brake pedal will have a slight car rock jump, and this beating will also be transmitted to the steering wheel through the relevant steering system, resulting in the steering wheel shaking left and right. After grinding the brake disc, it can be reused, and sometimes the pressure of the booster pump is the highest, producing a sound Do you have any other questions that I need to answer for you?
