What causes a car steering wheel to be heavy?

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.

The steering wheel is getting heavier and heavier, referred to as the direction heavy, mainly due to the following reasons:1Insufficient booster oil.

Power steering oil is a kind of medium oil used in the automobile power pump pump, which plays the role of transmitting steering force and buffering, and the power steering oil needs to be replaced regularly to check whether it is leaking, and when the power oil is insufficient, the direction will be heavy and heavy. 2.Tire pressure is too low.

Tire pressure that is too low can cause tires.

Car steering wheels are heavy for the following reasons:

In the case of electronic power steering, the power steering motor is faulty, resulting in a heavy steering wheel.

If it is hydraulic power steering, it is the power pump of the steering machine that is damaged, resulting in a heavy steering wheel.

Dust enters the steering column gimbal joint, causing the gimbal to get stuck and causing the steering wheel to be heavy.

The inside of the steering machine is damaged.

The front tires lack air pressure, resulting in a heavy steering wheel.

It is recommended to go to the 4S store for inspection to avoid serious aggravation of failures and safety problems!

There are several reasons why a car steering wheel is heavy:

1) The oil seepage of the oil pipe of the booster pump is heavy in the direction of oil shortage.

2) The belt of the booster pump is broken, and the booster pump does not work in the direction of heavy.

3) The booster pump is broken and does not work in a heavy direction.

See if the amount of booster oil is enough, and if it is not enough, it must be added. Second, see if the belt is broken.

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 bearing of the steering gear or steering column is 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 tire pressure is insufficient, 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 a professional maintenance technician to adjust the preload of the pinion;

1) The oil seepage of the oil pipe of the booster pump is heavy in the direction of oil shortage.

2) The belt of the booster pump is broken, and the booster pump does not work in the direction of heavy.

3) The booster pump is broken and does not work in a heavy direction. The solution to the heavy steering wheel of the car:

1. Check whether the power steering pump is faulty in oil pressure or oil circuit.

2. Go to the 4S store for re-testing.

Precautions for the use of the steering wheel:

1. Stick both hands on the left and right sides of the edge of the steering wheel. Hold the four fingers inwards and the thumb naturally on the edge of the steering wheel, and do not bend to the inside of the steering wheel. This grip is relatively close to the other control parts of the right hand, which is easy to operate.

In addition, when the right hand controls other parts, it is also convenient for the left hand to effectively grasp the direction.

2. When using the steering wheel, both hands should cooperate with each other and exert appropriate force. When turning the direction, one hand is the main hand, and the other hand is supplemented, pushing or pulling appropriately. If you turn to the left, you will be driven to the left with the right hand, and the left hand will be used as a supplement to pull the steering wheel, and when the vehicle enters a new route and needs to turn the steering wheel, you can still use the right hand to turn right.

The left hand can also be pushed appropriately.

The reasons why the steering wheel is too heavy when the car is steering, in addition to the insufficient tire pressure, the increased front load of the vehicle, and the small diameter of the steering wheel, are mainly due to:

The direction (direction machine) is not installed properly, the internal clearance of the direction machine is too small, the friction surface is rough or abrasive, the worm mandrel is bent, and the steering arm shaft and bushing are bitten.

The steering kingpin (vertical shaft) is too tight or bites with the bushing, and the steering knuckle kingpin pressure bearing is severely worn or rolled.

There is no "toe-in" or "negative toe-in" in the steering front wheel, which makes the tire and the road surface eccentric, and the front cross member bends and twists to cause the caster of the kingpin, backward tilt and wheel camber.

When the steering wheel is too heavy, the front wheels should be lifted up and suspended, and the steering wheel feels light and heavy, if it is still heavy, you can loosen the steering sleeve and the seat clamp of the cab and try again; If it is still too heavy, you can disconnect the big head of the steering arm from the thin star key of the steering arm shaft and try again; If it still doesn't work, it's a problem inside the steering machine. At this time, you can move the front wheel by hand, feel whether the steering kingpin or pressure bearing is blocked, if you can not find the fault above the steering arm, and it is not the knuckle that is blocked, you have to consider whether the steering wheel "toe" is abnormal. If the toe-in is normal after measurement, it is necessary to consider whether a series of inclination changes are caused by the deformation of the front crossmember, so that the steering mechanism can not work normally.

Whether the front beam is damaged and deformed, the driver is clear, if the front wheel has been violently impacted during driving, it is necessary to consider the warranty front beam, and the problem of excessive direction will be solved.

Generally, the steering wheel is too heavy, which is not properly installed after the warranty steering machine, and the steering machine and the cab resist. The reason is that the lower part of the steering machine is first bolted, and then the upper pipe wall of the steering machine is forced to be tightened with the seat, so that resistance is generated when the steering shaft rotates. If the steering machine first fixes the upper part and then the lower part, the resistance resistance of the rotating shaft disappears.

Although the wheel "toe-in" has been adjusted during the warranty, after a stage of vehicle operation, the wear of each active part, the looseness of the steering kingpin and the bending of the tie rod formed by the vehicle's attack have changed the "toe-in" of the wheel. If the toe-in can be restored in time, then the "toe-in" abnormality will not only increase the wear of the tires, but also cause the vehicle to roll over because the tie rod is not locked. Therefore, the anomaly of the steering wheel being too light should be paid attention to.

Hello, happy to answer your questions.

Hello, happy to answer your questions.

The steering wheel is heavier after just starting, if the car is hydraulic power steering, because after this just start, the viscosity of this hydraulic power steering oil is relatively high, so this general direction is heavier. If it is electronic power steering, this phenomenon needs to check the steering torque sensor to see if there is a problem, and check the pressure bearing on the shock absorber to see if there is a lot of wear.

Questions. There was no such phenomenon before, it was last winter, it was fine this summer, and now it is cold again.

What kind of car model are you?

Questions. I bought a Toyota Vios in 2005.

This is hydraulic power steering. There is this phenomenon in winter, mainly in the case of low temperature, the viscosity of the steering power oil is relatively high, and it is recommended to replace the power steering oil.

Questions. I changed the oil this spring, and it was good at the time, but now it's cold and it's not good, and some people say it's a problem with the steering belt.

Check the belt to see if there is any slippage. If the belt is not slipping, there may be a problem with the power steering pump. This phenomenon occurs at low temperatures, especially when the temperature of the power steering oil is low.

Questions. Ok thanks.

You are welcome. Questions.

It's just that you can't turn when you start to start, just get up and take a step.

In this case, it may be that the belt is slipping, or the power steering pump will start if there is a problem, and this phenomenon will occur when the speed is relatively low.

1. Analysis of the reasons why the steering wheel of the car is very heavy.

1. Insufficient booster oil.

Booster oil is the main driving force for the car**, so when the booster oil is insufficient, it is naturally difficult for the car to drive, let alone turn and change direction.

2. Help the uncleanness of the oil.

If it is difficult to move the steering wheel when the car is steering, it is possible that the booster oil is mixed with unclean mixed gases or impurities, which causes the booster oil to be unable to be used 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.

Second, the car steering wheel is very heavy solution.

1. Replace the booster oil.

The long-term use of booster oil may lead to unclean booster oil, and in this case, the booster oil should be replaced as soon as possible to ensure the normal operation of the car.

2. Check the booster system.

Most of the accessories in the car rely on electricity to drive the work, so when the steering wheel is not easy to use, you should check whether there is a problem with the booster in time and drive the car to the repair shop for professional repairs.

3. Ensure that the front tire pressure is sufficient.

If the steering wheel becomes heavy when steering, you can check whether the air pressure in the front wheels is sufficient, and if the air pressure is not enough, it should be added in time to ensure the normal driving of the car.

If the steering machine is broken, it will produce abnormal noise, the direction will become heavier, and the stroke will be too large, and the steering wheel may not obey the call, which will affect the driving safety.

Generally, there are several reasons for the failure of the direction machine:

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 spacer behind the spring. 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.

3. Lack of oil, the system has air.

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.

Faulty booster pump, faulty steering, lack of oil, or blocked return filter in the power steering system or oil reservoir.

Here's why the steering wheel is heavy and doesn't move:

1. Failure of the booster pump: when the pump pressure of the booster pump does not reach the standard value, there will be a heavy phenomenon when using the steering wheel, and the flow control valve needs to be checked.

2. Steering machine failure: when the steering engine power oil pressure is low, there will be a phenomenon of heavy direction, if it is due to the steering wheel oil pressure caused by the steering wheel becomes heavy, you need to go to a professional manufacturer for repair, it is not recommended that the owner deal with it by himself.

3. Lack of oil or air in the steering power system: When there is air in the steering system of the car, not only the steering is heavy, but also there will be noise during the steering, which needs to be dealt with in time to avoid greater losses.

4. Blockage of the oil return filter in the oil storage tank: When the oil return filter in the oil storage tank is not maintained or replaced for a long time, it is easy to cause blockage, resulting in poor circulation of the booster oil and heavy steering wheel.

The reasons are: one. The oil leakage oil cup of the booster pump oil pipe is heavy in the direction of oil shortage. Second, the belt of the booster pump is broken, and the booster pump does not work in the direction of heavy. Third, the booster pump is broken and does not work in a heavy direction. One or two are very likely.

There are several reasons why a car steering wheel is heavy:

1. The steering wheel is locked.

The car has a simple anti-theft measure where the steering wheel locks automatically when the car is turned off. When encountering such a situation, the first task is that the car owner can first try to twist the key with his right hand and turn the steering wheel with his left hand, and most of these sub-steering wheels will be automatically unlocked.

2. The belt of the hydraulic booster pump is too loose.

If the car is hydraulically assisted, we need to detect whether the booster oil is missing, or whether there is oil leakage, etc., if the above conditions are basically not, check whether the booster pump belt is too loose, and whether the oil is too dirty, these problems may basically affect the weight of the steering wheel.

3. Flat tires.

Detect whether the tire pressure of the car is normal, whether the tire is leaking, if it is leaking, it needs to be inflated immediately.

The reason why the steering wheel shakes and vibrates.

1. When the speed of the car reaches 80-90 kilometers per hour, the steering wheel trembles and vibrates.

The vast majority of such conditions are affected by tire deformation or transmission system, detect whether the front wheel alignment angle and toe of the vehicle meet the requirements, if there is a failure criterion, it should be adjusted immediately, and whether the tire balance of the vehicle is deformed or not, and it can be replaced immediately.

2. The car is driving on a flat ground normally, and the steering wheel trembles when it touches the pothole.

Most of these conditions are caused by the wear of the tie rod ball joint or the irregularity of the tire, so you should go to a professional repair shop for repair immediately.
