What about the car 120 yard car shaking

It may be a manifestation of poor dynamic balance between the two front wheels of the vehicle, and the downward dynamic balance can be adjusted.

The wheels of a car are made up of tires and hubs, but due to manufacturing reasons, the mass distribution of all parts of this whole cannot be very uniform.

When the wheels of the car rotate at high speed, a dynamic imbalance will be formed, resulting in the phenomenon that the wheels of the vehicle shake and the steering wheel vibrates while driving.

1. Dirty air filter: The air filter is designed to protect the engine and reduce wear, generally replaced in about 10,000 kilometers, if the replacement is not timely, there will be insufficient air intake to cause low idle speed, and the engine shakes, as long as the filter element is replaced, it can be solved.

2. High-voltage line break: High-voltage line breakage refers to the high-voltage wire core break, which can affect the ignition and cause the engine to shake.

3 Spark plug life:

The spark plug has a lifespan, and the ignition efficiency is significantly reduced after more than 3-40,000 kilometers, and can affect the ignition, which is the most common failure.

4. Low idle speed: The engine idle speed value has been set in the computer, and when the number of revolutions is low to a certain range, the car computer will automatically adjust it. If the idle speed is too low and the jitter is beyond the control range of the computer, some cars have adjusting screws on the throttle to adjust the idle speed, and some cars can not adjust, this kind of car can check the idle valve, throttle, air flow meter, vacuum sensor, adjust the ignition time (car with distributor), you can increase the idle speed.

Low idle speed can occur even when the water temperature is low, so you can check and replace the thermostat.

5. The water temperature is abnormal:

There is a normal range of engine operating temperatures, and high water temperatures will cause earlier ignition times, changes in the oil-air mixing ratio, thinner oil viscosity, and worse lubrication performance. The general fault cause is the jitter caused by the lack of antifreeze, the thermostat cannot be opened, the fan does not rotate, and the temperature of the temperature control switch is inaccurate.

6. Fuel injector plugging:

The fuel injector of the EFI vehicle is a key component of automobile fuel injection, and the service life is very long, which can reach hundreds of thousands of kilometers. However, because there is gum in the gasoline, the fuel injection hole of the fuel injector will be blocked, so the amount of fuel injected by each fuel injector is inconsistent, resulting in the inconsistent work of each cylinder and causing the engine to shake. The solution is to remove it and clean it.

7. Carbon deposits, oil scale blockage:

The throttle, idle valve, and air intake hole will be blocked by carbon deposits, oil scale, and poor air intake after a period of use, which will affect the stable idle speed and shaking. It is necessary to inspect and clean the above parts with cleaning agent, and there is no need to remove them for cleaning.

8-cylinder low pressure: the engine has 3 cylinders, 4 cylinders, 5 cylinders, 6 cylinders, 8 cylinders, if one cylinder does not work well, there will be a lack of cylinder phenomenon engine shaking. Three-cylinder engines are the most obvious, followed by four-cylinders.

Check the cylinder pressure with the cylinder pressure gauge, and solve the fault of low pressure with Xinba. Xinba has a unique effect on low cylinder pressure and unbalance. It can be added to the engine oil or directly added to the cylinder to restore the balance cylinder pressure.

What is the car shaking Knowing these three points you won't be pitted!

Directional jitter: The frequency of jitter increases with the increase of vehicle speed, or the jitter of a certain speed is not obvious above or below the speed of the vehicle. If the steering wheel is shaking from side to side, it is generally a problem of four-wheel alignment or tire dynamic balance; If it is vertical shaking or vibration, it is generally a problem of deformation of the wheel hub or tire.

If the dynamic balance is not a problem, you can first change the 2 front wheels and the rear wheel, if it does not shake, it means that the tires or wheels are deformed; If it's still shaking, you'll need to redo the wheel alignment.

This is a problem with tires, first balance the tires and change them to run, if there is still a problem, then do four-wheel alignment, to see if the tires are too serious to eat tires and need to be replaced.

Hello, this depends on the degree of jitter, a slight jitter should be caused by resonance, and it is generally fine. If mine is helpful to you, please set it to the best.

Hello: There is resonance, it is recommended to do a dynamic balance try.

I believe that many car owners have driven on the high-speed road, and many drivers pay special attention to the driving safety of the car due to the high speed in the high-speed road. When the speed of the car reaches 120 yards, the body of the car shakes very obviously, and this is caused by two reasons, the first reason is because of the different tire pressure of the car; The second reason is a malfunction in the suspension system of the car's tires. Both of these reasons can cause the car to shake when driving on the highway.

1. The tire pressure of the car is different, which leads to the occurrence of this phenomenon.

The tire pressure of car tires is very important for cars, especially on highways, car owners must focus on checking the tire pressure of cars. When the tire pressure of the car is different on both sides, then the car driving on the highway will cause the car to shake, because the tire pressure on both sides of the car is inconsistent, it will cause the force of the tires on both sides to be different, which will cause the problem of body shaking. At the same time, the tire pressure problem also affects the safety of the car, if the tire pressure is too large, it will not lead to a tire puncture, and it is very dangerous to drive on the highway car tire puncture.

Second, the failure of the automobile suspension system will also lead to this kind of problems.

The suspension system of the car is very important for the car, and the quality of the suspension system of the car directly affects the comfort of the driver. When the car is driving more than 120 yards on the highway, if there is a problem with the suspension system of the car, such as the bearing position in the suspension system is seriously worn, and the rubber sleeve is seriously aged, these problems will lead to the phenomenon of body shaking. <>

3. Summary. In general, when the speed reaches 120 yards, the owner feels that the body shakes significantly, then it is caused by the inconsistent tire pressure on both sides of the car's tires and the failure of the car's suspension system. Therefore, at this time, the owner must reduce the speed of the car to prevent traffic safety accidents caused by car tire punctures, and then go to a professional auto repair shop for targeted inspection and maintenance.

At that time, when the owner was driving on the high-speed road, he must check the tire pressure of the car and the condition of the car in advance to ensure the safety of the car owner during the trip. <>

This is a relatively normal phenomenon, when the wheels of a car rotate at high speed, it will form an unbalanced state, resulting in the car shaking in the process of driving, of course, it may also be that your car has other parts of the fault, you should go to a professional 4S shop for inspection, if not, you don't need to care too much.

The shock absorber is not working well and cannot absorb the vibration well, so the shock absorber can be checked and repaired or replaced if it fails.

This is mainly due to the air pressure difference between the tires, which causes the car to shake when the wheels have different abilities to absorb vibrations.

If your car is driven to 120 miles, the body shakes and there is usually a problem with the dynamic balance. Wait until you get home and do a balancing, and the problem will be solved.

1. The car will shake when it reaches 120 yards, which may be a manifestation of poor dynamic balance between the two front wheels of the vehicle;

2. The performance indicators usually used to evaluate the car mainly include power, fuel economy, braking, handling stability, smoothness and passability;

3. The dynamics of the car are expressed by the average driving speed that the car can achieve when driving in a straight line on a good road surface.

Summary. If the body will shake more than 120 yards, this phenomenon occurs, this is the need to do 4 wheels of dynamic balance, see if there is a problem with the data of 4 wheels of dynamic balance, if there is no problem, it is necessary to check the position of the rubber sleeve connection of the arm under the half-shaft ball cage, to see if there is any looseness or the gap is relatively large. Target.

If there is no problem, it is necessary to check the engine, look at the engine and gearbox, and see if there is a large vibration at high speed, these are all things that need to be checked.

The speed of the car is more than 120 yards, and the body is shaking.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

If the body will shake more than 120 yards, this phenomenon occurs, this is the need to do 4 wheels of dynamic balance, see if there is a problem with the data of 4 wheels of dynamic balance, if there is no problem, it is necessary to check the position of the rubber sleeve connection of the arm under the half-shaft ball cage, to see if there is any looseness or the gap is relatively large. Target. If there is no problem, it is necessary to check the engine, look at the engine and gearbox, and see if there is a large vibration at high speed, these are all things that need to be checked.

1. This has something to do with the design of the center of gravity of the car. We all know that some sports cars have a low center of gravity, so they are designed to reach speeds of more than 300 kilometers per hour, and on the other hand, a sedan is generally more stable at high speeds than SUVs of the same platform. Therefore, the lower the vehicle's center of gravity, the better the stability at high speeds and the better the handling.

2. It is related to the aerodynamic design of the car. This is what we usually call the drag coefficient, the lower the drag coefficient, the better the stability at high speeds. Generally speaking, according to a good design, the speed of the air flow under the car should be greater than the speed of the air flow above the body, and this difference in air pressure will cause the air to press the car firmly on the ground (the so-called air downforce), and the faster the speed, the more obvious the effect.

3. It is related to the suspension design of the car. The suspension of the car is hard and soft, the spring travel of the hard suspension is short, the body is stable, but the shock absorption is not ideal, and the body bumps are more serious. The soft suspension spring travel is long, the body stability is poor, the body shaking response is more sensitive, the high-speed stability is poor, and the soft suspension will have a more intense response when it encounters a cross wind or strong air flow.

Hello high-speed driving body shaking, mainly two aspects:

1.The dynamic balance of rotating parts such as tires and half-shafts is not good, and centrifugal force causes the vehicle to shake;

2.The transmission efficiency of the engine and gearbox is low, and the lack of power causes the vehicle to shake during driving.

If the body shakes only at about 120 yards, it may be caused by body resonance. Other situations are possible. Resonance is the most likely.

Whether the chassis is bumped, go to the next four-wheel alignment, and you will know it after you finish it, and adjust it.

What's the deal with 120 yard body shaking? What's the deal with 120 yard body shaking? The reasons why the car shakes violently when driving to 120 mph are as follows:

1. There is an air pressure difference between the tires, and the wheels have different ability to absorb shocks, which causes the limbs to shake. Re-inflate the tires so that the air pressure between the tires is consistent. The air pressure of a passenger car tire is generally in between.

2. The transmission shaft is deformed and bent, and the transmission ball head is worn too much, resulting in the vehicle shaking. The transmission shaft can be removed to do dynamic balancing and the transmission ball bearing can be replaced. 3. There are differences in the toe of the vehicle and the camber angle of the kingpin, resulting in body shaking.

The numerical value of each inclination angle can be adjusted by destroying the vertical four-wheel positioning, and the remaining fast removal problem can be eliminated. 4. The shock absorber works poorly and cannot absorb the vibration well. Check the shock absorbers and repair or replace them if they fail.

5. The machine mat is seriously aged, and the vibration generated when the engine is running cannot be absorbed and transmitted to the body. Remove the old pad and replace it with a new one. @2019
