When the steering wheel becomes heavier, do you need to add power steering oil?

Quote: Engine oil **** netizen 01:23 Posted on the 1st floor Taking the co-pilot's position as the left side, there is probably a pink oil pot behind the left headlight, which is the direction oil can, look at the liquid level.

If it's okay, it's probably caused by you adjusting the height of the steering wheel, which is said to be heavier when the steering wheel is lowered. Or you have something else wrong with your car. I double-checked.

The pink liquid level is standard, the steering wheel has not moved, and the tire pressure is appropriate, but it feels like the direction is much heavier than before. The car feels underpowered, could it be related to the gasoline I added this time? In the past, it was added at one gas station, but this time it was added at another house.

It seems that you can only go to 4s to check it.

I used this tank of oil and looked at it, this car is like this.

The power pump is replaced, and the steering wheel is heavy probably because the power assist oil pipe is blockedThe relay controlling the steering machine is faulty. The steering power assist is mainly to assist the driver to adjust the direction of the car and reduce the force of hitting the steering wheel for the driver. Of course, power steering also plays a certain role in the safety and economy of car driving.

The reasons for the abnormal noise of the booster pump are as follows:

1. The oil leakage of the booster pump causes the oil level to be too low, resulting in abnormal noise when hitting the steering wheel;

2. Poor lubrication of the cold car of the booster pump leads to internal wear, resulting in abnormal noise;

3. The installation of the booster pump is not firm, which leads to abnormal noise during work.

Common faults in car steering wheels.

1. The steering wheel shakes.

When driving above medium speed, the steering wheel shakes strongly, and the chassis has periodic abnormal noises, which is likely to be due to the destruction of the balance of the steering transmission, and the transmission shaft and its spline shaft and spline sleeve may be excessively worn.

2. Steering weakness.

When steering, it feels heavy and laborious, which may be due to the rolling bearings of various parts of the steering system being too tight, poor bearing lubrication, and the ball head of the steering straight tie rod being too tight or lacking oil; In addition, the lack of air pressure in the front tires can also contribute to this situation.

The steering wheel becomes heavier after changing the booster oil, which is caused by the presence of air in the booster pump system. Turn off the engine, turn it all the way to the left, then hit the right all the way down, and so on. At least thirty times!

The air from the assistant pump system will be exhausted. In this way, the direction of the power assist system will not sink.

When changing the booster oil, first turn the car on and use the oil extractor to suck the old oil clean. Inject the new booster oil and turn the steering wheel back and forth to let the new oil penetrate, which also serves as a wash. In order to penetrate thoroughly, it is best for the owner to turn the direction left and right sharply, and then slightly turn the direction left and right.

The purpose of hitting the steering wheel back and forth is to drain the old oil in the steering machine, but not for a long time, otherwise it will cause the oil pressure to be too high and the steering oil will be sprayed. The oil in the booster tank is sucked out again, and then a new booster oil is injected, and the steering wheel is turned again. The third time the booster oil is sucked away, and the purpose of this repeated operation is to ensure that the old oil is completely removed.

Then inject new oil.

No oil can be mixed. When you take the car, you will hear a slight "hula" sound, and it doesn't matter, it is the oil circulating, and it will slowly return to silence. Experts remind that the car should not be left empty for a long time, otherwise it will destroy the booster pump.

The reason why the steering wheel of a car is heavy:

1. Insufficient booster oil.

Booster oil is the main driving force that drives our cars**, so when there is a shortage of booster oil, it is naturally difficult for our cars to drive, let alone change direction when turning.

2. Help the uncleanness of the oil.

If it is difficult for our car to move the steering wheel when steering, it is possible that our booster oil is mixed with unclean gas mixtures or impurities, which causes the booster oil to not work normally and pushes the car to drive.

3. There is a problem with the booster.

The relationship between the steering wheel and the booster is naturally inseparable, and when the steering wheel becomes heavy, it is likely that there is a poor circuit contact inside the booster system or some other problem.

Steering wheel. The reasons for the sinking are: 1. Insufficient booster oil, 2. Tire pressure.

Too low, 3, the bearing fit is too tight, 4, the booster problem, can be dealt with according to the actual situation.

1. Insufficient booster oil.

Generally, the feeling of the weight of the direction is relatively constant, if it suddenly becomes very heavy one day, or slowly becomes heavier, it may be that the steering power oil is dirty, it is similar to the engine oil, and it needs to be replaced. Or if there is less oil leakage, then there is less power, so the steering wheel becomes very heavy. In this case, it is necessary to maintain it in time, or to add and change the steering oil.

2. The tire pressure is too low.

If the tire pressure is too low, the area of contact between the tire and the road surface will increase, the friction will increase, and the steering difficulty will increase, resulting in a heavy steering wheel, which is not conducive to driving safety.

3. The bearing fit is too tight.

A rolling bearing is connected to each steering system.

It is also closely matched with the sliding bearing, so it will lead to the lubrication of the bearing can not be well run, which will affect the phenomenon of stagnation, causing the steering wheel to become sinking, this situation should check the mechanical part and the booster system, or rule out whether there is oil leakage inlet seal damage.

4. Booster problem.

The relationship between the steering wheel and the booster is inseparable, so when the steering wheel becomes very heavy, it is likely that there are some poor circuit contacts or other problems inside the booster system, which should be repaired by the 4th shop.

The reason why the steering wheel of a car is heavy:

1. If it is hydraulic assistance, check whether the booster oil is lacking, whether there is oil leakage, the lack of oil needs to be replenished to the normal range, and if there is no shortage of oil, check whether the booster pump belt is too loose, and if it is too loose, the belt needs to be tightened, and whether the oil is too dirty to cause poor fluidity, which is generally replaced once every 2 years or 60,000 kilometers.

2. If it is electronically assisted, check whether the fuse is burned out, and whether the line is open or short circuited to the ground.

3. Check the tire pressure, air leakage will also cause the direction to become heavier, so you need to inflate.

The throttle is heavy because the throttle is dirty.

Solution: Disassemble the place where the air filter is connected to the intake branch, and spray some carburetor cleaning agent into the throttle valve (break the throttle line with your hand to make a gas throttle shape, then the valve in the throttle valve body will be opened, so that the area that can be cleaned will be a little more), and at the same time wipe it in with a clean cloth, which will clear out some black dust.

The reason why the steering wheel is scattered and the steering power has become heavier: 1. The power assist oil is insufficient, and the power assist oil is the main driving force to drive our car**, so when the power assist oil is insufficient out of the chain mountain, our car will be difficult to drive, let alone turn and change direction; 2. The booster oil is not clean, if it is difficult to move the steering wheel when our car is steering, it may be that our booster oil is mixed with unclean mixed gas or impurities, which will cause the booster oil to be unable to be used normally; 3. If there is a problem with the booster, the relationship between the steering wheel and the booster is naturally inseparable, when the steering wheel becomes heavy, it is likely to be caused by poor circuit contact or other problems inside the booster system.

The reasons for the power of the steering wheel of the car to become heavier are: 1. The fit between the rolling bearings and the sliding bearings connected to the steering system is too close: it will lead to the decline of the lubrication effect of the bearings and the formation of stagnation, which reflects the performance of the steering wheel.

2. The pump pressure of the booster pump does not reach the standard value: there will be a heavy phenomenon when using the steering wheel, check the flow control valve, during driving, the leakage of the flow control valve or safety valve can be repaired by grinding, and then check whether the spring of the safety valve fails. 3. The power assist oil pressure of the steering machine is low

Due to the steering oil pressure caused by the direction of the trouser pant becomes heavy, it is necessary to go to the state sales repair shop for repair in time. 4. The oil return filter in the oil storage tank is not maintained or replaced in time for a long time: the circulation of the booster oil is not smooth, and the steering wheel becomes heavy.

If you find that the booster oil is lower than the scale, the oil is thinner, or the color of the oil is darker, it means that the booster oil needs to be replaced.

1.When changing the booster oil, take a taxi first and use the oil pump to suck up the old oil.

2.Fill in the new booster oil and then turn the steering wheel back and forth to let the new oil penetrate in, which can also play a cleaning role. In order to penetrate thoroughly, it is best for the owner to make a large left and right turn of the limb first, and then turn left and right in a small way.

However, experts remind that the purpose of turning the steering wheel back and forth is to drain the old oil of the sock whisperer, but do not kill the steering wheel for a long time, otherwise it will cause excessive oil pressure and make the steering oil spray out.

3.Suck out the oil from the booster tank again and then inject new booster oil. Then, turn the steering wheel again.

4.The third time to suction the booster oil. The purpose of this repetitive operation is to ensure that the old oil is completely removed. Then inject new oil. Experts warn that no oil can be mixed.

5.When driving, you will hear a slight "hula" sound. It doesn't matter, it's just that the oil is circulating, and it will slowly return to silence. Experts warn that the car should not be empty for a long time, otherwise it will destroy the booster pump.

The directional assist oil needs to be replaced. In most cases, the replacement interval of the booster oil is 3 years and 40,000 km. But this is not absolute.

In many cases, the booster oil does not need to be replaced for three years, but depends on the actual situation. Check whether the booster oil is dirty, foaming, whitish, black, etc. All mean that the booster oil is contaminated and needs to be replaced in a timely manner.

Steering wheel power assist is to help the driver reduce the force of the steering wheel, and power steering also plays a certain role in the safety and economy of car driving. When the car is turning, the torque (steering) sensor senses the torque of the steering wheel and the direction in which it is going to turn, and these signals are sent to the electronic control unit via a data bus. The electronic control unit will send action instructions to the motor controller according to the data signals such as transmission torque and direction to be steered, so that the motor outputs the corresponding steering torque according to specific needs, so as to generate power steering.

The power steering systems equipped on automobiles can be broadly divided into three categories: mechanical-hydraulic power steering, electro-hydraulic power steering, and electric power steering. The power pump provides power for the power steering system and is the first power of power, while the power oil is the medium of power transmission.

Power oil is not only used to transmit power, but also to lubricate. Therefore, when the booster oil is contaminated or deteriorated, it should be replaced in time to avoid damage to the hydraulic system due to excessive wear.
