Where is the reason for the sinking of Wuling Hongguang

The reasons for the direction sinking are as follows:

1) Failure of the booster pump.

When the pump pressure of the booster pump is judged to be less than the standard value through the test, it is obvious that the direction is heavy and related to this. First of all, it is necessary to check whether the meshing surface between the flow control valve and the valve seat and the steel ball of the safety valve are not tightly closed. If the flow valve or safety valve is leaking, it can be repaired by grinding.

Secondly, check whether the spring of the safety valve has failed. This can be checked by adding a gasket behind the spring, if the maximum pump pressure increases significantly after adding a gasket behind the spring, it means that the spring fails. If there is no problem in both parts, the dismantling booster pump should be dismantled and the cavity wall of the vane pump should be observed for wear and strain.

Due to the strain of the cavity wall, the high and low pressure cavities will be connected, resulting in the pressure cannot be established. Generally, the cause of strain is oily dirt. If the direction is suddenly heavy, it should be checked to see if it is caused by a broken pump shaft.

2) Steering machine failure.

If it is found that the power assist oil pressure of the steering machine is low through inspection, it is explained that the cause of the heavy direction is in the steering machine. In this case, you should ask a professional manufacturer to repair it. Generally speaking, most of the steering machine failures are due to the piston and cylinder strain, or the damage of the sealing ring on the piston, resulting in the communication of the two chambers of the piston, so that the booster pressure can not be effectively established.

In addition, the damage of various sealing rings on the circumferential surface of the piston and the sealing ring on the steering screw will also cause high-pressure unloading and reduce the power assist pressure to the bottom.

3) Lack of oil, there is air in the system.

4) The oil return filter in the oil storage tank is blocked.

The oil return filter in the oil storage tank is not maintained and replaced for a long time, resulting in blockage, poor circulation of booster oil, and increased back pressure of oil return, which will also make the direction heavy.

5) The sealing rings of the two limit valves fail, so that the two chambers of the piston are connected, resulting in the failure of the booster.

The reasons for the steering wheel sinking are: 1. Insufficient booster oil, 2. Tire pressure is too low, 3. Bearing fit is too tight, 4. Booster problem, which 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.

For a rolling bearing 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 power assist system, or rule out whether there is a leakage of the inlet seal damage phenomenon.

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.

Hello! There are many reasons for the heavy direction:

1: The steering machine is short of oil, maintain the steering machine.

2: The gap of the front suspension system is too large, and the lower arm can be replaced after inspection.

3: Turn to the ball head loose mine, and change it after the inspection.

4: Measure the forward speed (i.e. the direction of the steering angle).

5: Check whether the direction booster is leaking oil, or whether the booster oil is missing.

6: Check whether the tire pressure is too low, or whether the pattern is worn off, if the wear deviation is the front lower arm damage, the replacement can be.

7: If the first few items are not, then you'd better do a wheel alignment.

Hope it helps, hope, thank you!

There are many reasons for mistracking, such as insufficient air pressure of the tire, different degrees of tread pattern wear, problems with the design of the suspension system, suspension injuries, deformation, displacement, etc.

Automobile deviation is the process of driving in a straight line on a flat road, and the car deviates to one side by itself, resulting in the inconsistency between the center line of the front and rear axles and the center line of the driving trajectory. If the deviation is light, it will cause tire gnawing and tire scrapping, and at worst, it will cause tire burst, vehicle loss of control and other dangerous conditions.

If the situation is light, it will cause tire gnawing and tire scrapping, and if it is serious, it will cause tire bursts, vehicle loss of control and other dangerous situations. According to the survey, for ordinary family cars, the probability of surviving a puncture at 150km h is less than 20%; Although deviation is not a problem that can make the car break down immediately, there are still many hidden dangers in long-term driving deviation of the vehicle, and if deviation occurs, it should be checked and repaired in time.

Hello, this situation first check whether the front wheel pressure is normal, if the air pressure is inconsistent, there will be a direction deviation, you need to put the two front wheel pressure, supplement to the same, to return to normal, if the tire pressure is normal, this is generally the tire positioning is not accurate, you need to do a four-wheel alignment, correct the tire position, to return to normal, to ensure driving stability, timely maintenance to ensure that the driving is stable, comfortable and safe, thank you.

Check to do positioning, if the steering wheel is crooked, it is easy to adjust without using the locator (find an experienced master to adjust it according to the crooked angle.) If the steering wheel is tilted to the side after letting go, it will be troublesome to adjust.

Is your car ready? My car sometimes runs 40 horses and then runs to the right, the same road and the same speed is better, what's going on? The four-wheel alignment has been done countless times, and the tires are all new.

Hello, let's see if the tire pressure is consistent. There is no space in the site part, ball head, lower swing arm, if not, do four-wheel alignment.

Check your tires for uneven wear and tear, followed by a four-wheel alignment.

Check the chassis to do the four-wheel alignment.

It is recommended to do a four-wheel alignment first.

Check the chassis to make a positioning.

It seems that this situation is mainly caused by the wrong wheel data, and it is recommended that you go to the repair shop to do a four-wheel alignment.

You can try to do a four-wheel alignment, if it doesn't work, the problem is not small, it is recommended to enter the store immediately to check it!

The steering wheel shakes when the car is idling, which is very common, and some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake.

Generally, the symptoms can be solved after replacing the brake discs and brake pads. If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

Summary. In this case, there are two main reasons to consider, the first thing to consider is that the steering system of your machinery and the chassis data are not right, so this needs to do the four-wheel alignment to adjust the chassis data, if the data is normal, then you have to consider the second situation, that is, your steering power system is faulty, so you can test the power steering system through the computer to see if there is a fault.

In this case, there are two main reasons, the first thing to consider is that the steering system of your machinery and the bottom dust source disk data is not right, so this needs to do a four-wheel mountain positioning adjustment chassis data, if the data is normal, then you have to consider the second situation, that is, your steering power system is faulty, so you can test whether the power steering system is faulty through the computer.

1. The steering machine lacks lubricating oil;

2. The ball head is damaged;

3. The toe-in value is incorrect;

4. Low air pressure on the front wheels;

5. There is a problem with the steering machine;

6. There is a problem with the bearing of the steering wheel;

7. Increase the size of the tire.

You can check them one by one.

It could be a problem with the steering machine.

It depends on whether you have been going to the repair station to do the maintenance, and the warranty time of each part is different, depending on your maintenance manual

It is recommended to check the booster oil, steering machine.

I just bought a Wuling freight car on 2020, 9, 2, just left the factory in July, or the national sixth, the direction is good and heavy when reversing, what is going on.

If you still feel that the direction is sinking when the car is empty, it is that your skills are not at home! Let's drive a car!

4S shop go scrapped hehe.

There are the following possibilities:

1. The oil of the power arm of the steering machine is leaking;

2. Caused by the drying of the lubricating oil of the steering system;

3. As you said, the bearing has a dead point;

4. The horizontal tie rod of the steering is deformed by impact.

Go to the usual maintenance area and ask them to check it.

As for the warranty thing, many times it is the maintenance site that says that it is a way to pit your money, remember to bring the maintenance manual when you go.
