What s wrong with the car struggling to play the direction?

It may be caused by insufficient power oil, low tire pressure, toe-in, steering machine, power booster pump failure, and overtight bearing fit. The specific reason why the steering wheel is hard to turn. 1. The power steering oil is a medium oil used in the car power pump to transmit the steering force and buffer, and the power oil needs to be replaced regularly to check whether it is leaking, and when the power boost oil is insufficient, the direction will be heavy.

2. The tire pressure is too low, and the tire pressure is too low, which will lead to more contact area between the tire and the road surface, increase the friction, and increase the difficulty of turning, resulting in a very heavy steering wheel, which is not conducive to driving.

3. Toe-in, toe-in can also affect the steering of the car, the meaning of toe-in is quite complex, simply put, it is to make the steering wheel automatically return to the right, to ensure that the car can drive in a stable straight line. Therefore, when there is a problem in this aspect, it will also cause the direction to sink.

4. Failure of the steering machine and booster pump. Also affecting the steering of the car are the steering machine and the booster pump, which can cause steering difficulties when there is any reason for these two important components. Whether it is universal joints, chassis suspension balance bars, plane bearings and other problems can not be ignored.

5. The bearing fit is too tight. The rolling bearings connected by each steering system and the East China bearings are too closely matched, which will lead to poor lubrication of the bearings and the formation of stagnation. It is necessary to check the mechanical part and the cause of the booster system, or rule out whether there is any seal damage such as oil leakage and air intake.

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.The bearings of the steering gear or steering column are damaged, resulting in heavy steering. This is mechanical damage and the bearing must be replaced.

3.The steering tie rod ball joint pin lacks oil or is damaged, resulting in heavy steering. If damaged, the ball pin must be replaced.

4.The front inner tire lacks air pressure, resulting in heavy steering. Check the tire pressure regularly and inflate the front tires at the prescribed air pressure.

5.The meshing gap between the steering gear pinion and the rack is too small, resulting in heavy steering. Ask professional maintenance technicians to adjust the preload of the pinion;

The reasons for the laborious rotation of the steering wheel of the car are: 1. The steering column is not lubricated and the friction is large; 2. Lack of steering booster oil; 3. Universal joint failure; 4. The chassis suspension balance rod lifting lug sleeve is aging; 5. Plane bearing failure; 6. Assist system failure; 7. Abnormal wear on the surface of the brake disc and brake pad; 8. The steering shock absorber is damaged. The solution to the laborious rotation of the car's steering wheel is:

1. Lubrication and steering string; 2. Replenish the steering booster oil; 3. Replace the universal joint; 4. Replace the chassis suspension balance rod lifting lug sleeve; 5. Replace the plane bearing; 6. Replace the steering shock absorber.

When the car is in the direction, if it is difficult, this should be to see if his power is broken, or whether his tire pressure is too small.

When the engine is turned off, it is in a state of stagnation, so that the motor vehicle has electricity and gives the engine a certain driving force. Nowadays, the dream of many of us is to own a car of our own. Some people may want a Mercedes-Benz BMW, while others may be content with a very ordinary car.

They are content with the pleasure of driving. At this time, we will find it difficult to turn the steering wheel with the engine turned off.

However, when the engine starts, the steering wheel turns easily. Why? It is heavier in the in-situ direction and lighter in the high-speed direction.

This is a normal phenomenon for hydraulically driven vehicles. When the vehicle is stationary, the friction that the wheels need to overcome in order to turn.

The largest, so it's normal to be a little heavier. In the past, there was no steering aid, so it was very laborious to move if it was not in place, and it would be much lighter to drive. Why is the direction shallower at high speeds?

It is formed by the superposition of several reasons. First of all, the engine speed is fast, and the power pump speed is also fast, and the power is sufficient. Secondly, due to the shape of the car, the faster the driving speed, the greater the lift force of the air acting on the car, reducing the pressure and friction of the wheels on the ground, so the directional rotation will be lighter.

This phenomenon is especially pronounced for hydraulically assisted vehicles. Nowadays, many electronically assisted vehicles have an added feature. When the speed is high, the direction will automatically increase, reducing the feeling of lightness and fluttering of the vehicle. The mechanical hydraulic pump is driven by an engine belt.

Direct drive. The most common reason for steering wheel weight is dirty steering oil. It's like the oil is dirty, which will affect the normal operation of the engine; When the steering oil is dirty, the steering wheel will get heavier and heavier.

Not only dirty, but also if there is less oil. If there is a problem with the steering oil, it is necessary to maintain it in time, or add or replace the steering oil.

In addition, in the mechanical-hydraulic power steering system, if a mechanical part fails, the steering wheel of the car will suddenly become immobile and heavy. First of all, the engine is at a standstill when it stalls and does not work properly. If the steering wheel of the engine can still turn when the engine is turned off, doesn't it need power and electricity?

Therefore, in the state of flameout, the car stops working, and only by giving the engine a certain amount of power can it run normally, turn the steering wheel, and keep working.

This is because if you play in the same direction, the friction between the tires and the ground is very large, and when you move, the friction is much smaller, so this is the case.

However, the previous hydraulic assist and non-assisted steering system made it easier to play the direction while driving. And no matter what the steering system, the steering system must exert more steering force on the wheels when playing the direction on the spot than when driving.

The wheels do not rotate when they are in place, and the steering system must provide enough friction between the tires and the ground to deflect the wheels, which naturally requires more steering force. Therefore, for the steering system itself, more steering force must be provided to steer the wheels when the direction is played on the spot, while the steering system only needs to provide a small amount of force to steer the wheels during driving.

This is because if you hit the steering wheel on the spot, the friction between the tires and the ground will be directly expressed on the wheels, and it is more difficult to play the steering wheel, so you need to overcome the friction.

Because the left hand is suitable for pulling, and the right hand is suitable for pushing.

It's okay, new converter, it's normal.

1.The steering power is not good to use the reason why the steering wheel is laborious:

1) Less steering oil leads to power failure, 2) Insufficient pump oil pressure due to internal wear of the steering machine booster pump (solution: replace the booster pump) (3) Damage to the direction machine grind causes power failure (maintenance method: replace the direction machine), (4) The direction oil pipe is blocked and causes the direction to be heavy, 5) The front tire pressure is low (the tire pressure can be hit to kilograms) can be checked according to the above maintenance ideas.

Check that the wheels and air pressure are consistent.

Check the wheel alignment and steering knuckle for damage.

The steering machine itself failed.

Steering tie rods and other suspensions are in the making.

Insufficient steering fluid or malfunctioning steering pump.

What should I do if the steering column lock integrated switch fails?

Diagnostic Help: The vehicle anti-theft subsystem is capable of electrically locking or unlocking the steering system.

The seedling power mode is converted to non-off mode and there is a verified driver ID, and the Xunzhu lock Cong Tansui control module can be unlocked.

Qingqiu. Troubleshooting: Clear all troubleshooting codes in the bar of Run Troubleshooting Codes.

f, the integrated switch that operates the steering column lock. No fault diagnosis code is set.

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.

1. Pseudo-faults.

1. You can see if you have changed the driving mode, different driving modes have different requirements for steering wheel sensitivity, and some will make you feel heavier.

2. Check the tire pressure, if the tire pressure becomes low, the contact area between the tread and the ground becomes larger, the friction is large, and the steering wheel will naturally feel heavier. Of course, this feeling is very slight.

3. The four-wheel alignment needs to be re-aligned, and there are two parameters in the four-wheel alignment, the caster angle of the kingpin and the camber angle of the kingpin will affect the steering resistance of the steering wheel.

Two. Steering related component failures.

1. Plane bearing wear: The plane bearing on the shock absorber, also known as the pressure bearing, its function is the active connection between the shock absorber and the car body, if it is worn, it may make the steering heavy, but its damage is also agreed.

There was a rattling sound in the direction of hitting.

2. Failure of the steering machine: such as the corrosion of the universal joint of the steering machine, the damage of the solenoid valve, etc.

3. Failure of the power steering system.

Once there is no steering assistance, it is necessary for us to overcome the various moments inside to turn the steering wheel, and then the required force will increase greatly, and it will naturally feel very heavy. Mercedes-Benz's power steering control system depends on the model.

The different configurations can be divided into speed-sensing power steering system SPS, ECO power steering pump, electric steering system, hydraulic electric auxiliary steering system, dual pump power steering system, full hydraulic power assist, etc., to put it simply.

It can be divided into hydraulic power assist and electronic power assist.

1. Hydraulic assistance: This kind of power assist is mainly achieved through the establishment of hydraulic power pump to achieve power assistance, so if the power assist oil is not clean, missing, there is air, and the circulation is not smooth, it will affect the steering power.

2. Electronic assistance: This type is controlled by the electronically controlled power steering control module and ESP control module, and various information is analyzed, such as steering torque, wheel speed, steering angle and steering speed, engine speed, and steering electricity.

The rotor position of the machine realizes the steering assistance. Therefore, the control module and various related sensors can have an impact on the steering assistance. There are mainly steering torque sensors, wheel speed sensors, steering angle sensors, and motor position transmission.

Sensors, electronically controlled power steering control modules, and ESP control modules. In addition, whether these parts, control module wiring harnesses, and plug joints are in good condition will also affect their normal operation, which will indirectly affect the steering assistance.

There are three basic reasons why the car direction is heavy, 1There is no power aid.

2.There is power assist but oil leakage.

3.Tire imbalance or abnormal tire pressure.
