The steering wheel is heavy, what s going on?

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.

There are several possibilities, the first may be the lack of power steering oil, the second is the wear of the rack and pinion inside the steering machine, and the third is that the power steering pump is faulty, and the specific fault point needs to be checked before it can be determined.

Designed this way, to avoid losing control of the vehicle at high speed in potholes, Pajero is designed for rallying, you can find a continuous pothole section to drive and experience, the speed is slow and bumpy, and the speed is very stable.

1. This situation generally appears in the model of mechanical hydraulic power steering, which is a very common way of steering power in the past, referred to as HPS in English, with mature and reliable technology and low cost. This type of steering power assist converts a part of the engine's power output into hydraulic pump pressure, which exerts auxiliary force on the steering system to steer the tires. When the square loss pure to Bikong filial piety disc is not rotated, the pressure in the chamber on both sides of the piston is the same and is in a balanced state.

When the steering wheel rotates, the mechanical control valve connected to the steering column will be opened or closed accordingly, one side of the oil will no longer pass through the hydraulic cylinder and directly flow back to the oil storage tank, the other side of the oil continues to be injected into the hydraulic cylinder, the pressure difference between the two sides of the piston will be pushed under the action of the hydraulic force, and then produce auxiliary force, at this time we will feel that the steering wheel is not so laborious.

2. The steering pump drives the belt to slip. The steering pump is driven by a belt, and if the friction between the belt and the pulley is too small, the belt will slip on the pulley, and there will be a squeaky sound at this time. It may be caused by loose belt adjustment, excessive wear of the grooves of the pulley, or the new belt does not fit well with the old pulley.

A simple way to tell is to pour a little water on the belt when there is a loud manuscript, and if the sound goes away, it means that the belt is slipping. At this time, first adjust the tension of the belt, if there is still a sound after adjustment, you can use it for a period of time to make the belt and the pulley fully match and then see if it is still ringing, if it is still ringing, you have to replace the pulley.

What to do if the steering wheel of the car is abnormal.

1. The sound of rebounding the clip after the turn signal.

2. The sound of the dust jacket of the direction column.

Whether you are in place or driving as long as you hit the steering wheel, you will hear the sound coming from under the steering wheel, you should check the steering post dust jacket, once the steering post dust jacket lacks lubrication, it will produce a dry friction sound, you just need to apply some butter in the dust jacket This sound will disappear.

If the steering wheel of the car is heavy, you need to check the front tire pressure and the steering wheel power assist system to see if there is a problem.

The steering wheel is generally connected to the steering shaft by a spline, and its function is to convert the force acting on the edge of the steering wheel into torque and transmit it to the steering shaft. When steering with a steering wheel with a larger diameter, the driver's hand force on the steering wheel is smaller. The steering transmission shaft should be used as a connector between the steering gear and the steering shaft, which is conducive to the generalization of the steering gear, compensates for the errors generated during manufacturing and installation, and makes the installation of the steering gear and steering wheel on the vehicle more reasonable.

Sutar ( Check price |.)Detailed explanation of the model) The reason why the steering wheel is heavy:

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, there is no shortage of oil to check whether the booster pump belt is too loose, too loose need to tighten the belt, and check whether the oil is too dirty to cause poor fluidity, generally replaced once every 2 years or 60,000 kilometers.

If it is electronically assisted, check whether the fuse is burned out, and whether the line is open or short circuit to ground; Check the tire pressure, a flat air will also cause the direction to become heavier, so you need to deinflate.

The Sutar is equipped with an electronic steering booster. Hydraulic power steering has been canceled. If you feel that the steering wheel is a lot heavier than before, we can check the following points first:

First of all, first we need to check the tire pressure of the four-wheeled tires. If the tire pressure is too low, the friction area between the tire and the ground will increase, resulting in too much resistance to turning the steering wheel, so we will feel that the steering wheel is much heavier than usual.

Secondly, when checking the four-wheel alignment data of the car such as the spare car, if the four-wheel alignment is not done for a long time, the four-wheel alignment data will change greatly. When the rubber next to the steering wheel turns or returns, the return angle will become smaller or not in place, resulting in a heavy steering wheel rotation.

Third, check the top rubber bearing on the shock absorber. If there is a problem with this bearing, it will cause the steering wheel to turn excessively. Fourth, check whether the dust cover of the tie rod ball joint is damaged, resulting in the lubricating oil in the ball joint losing lubrication in contact with the outside dust, and the steering wheel feeling too heavy due to dry grinding.

Fifth, after the accident of the vehicle, there is a problem with the inside of the steering gear, and it feels too heavy when hitting the steering wheel.

If there is no problem with the above checks, it is recommended to drive the vehicle to a 4S shop for diagnosis and determine whether the steering system of the vehicle is normal.

Sutar steering wheel weight solution: 1. Replace the pressurized jujube oil. 2.Check the power system. 3.Check the tire pressure. The steering oil also needs to be changed regularly, usually every 2 years or 30,000 kilometers.

The reason why the steering wheel is heavy:

1.Insufficient pressurized oil.

Booster oil is the main power source to drive a car, so when the booster fuel is insufficient, it is naturally difficult for our car to drive, let alone turn and change direction.

2.Booster oil impurities.

If it is difficult for our car to move the steering wheel when turning, it may be that the booster oil of the Zen dismantling vehicle is mixed with unclean mixed gases or impurities, resulting in the failure of the booster oil.

3.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 that the circuit is in poor contact or there is another problem with the power assist system.

4.The tire pressure is too low.

Low tire pressure in cars can also cause the steering wheel to become heavier. In severe cases, it can even lead to a puncture due to insufficient tire pressure. Therefore, it is recommended to check the tire pressure and steering oil first when the steering wheel becomes heavier.

Pacific Automobile Network] The solution to the weight of the steering wheel: 1. Replace the booster oil. 2. Check the booster system. 3. Check the tire pressure. The steering power oil also needs to be replaced regularly, and it is generally replaced once every 2 years or 30,000 kilometers.

The reason why the steering wheel is 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 our car to drive, let alone turn and change direction.

2. Assist the oil to change the non-sharp branch clean.

If our car has difficulty moving the steering wheel when turning, it may be that the vehicle's booster oil is mixed with unclean gas mixtures or impurities, resulting in the booster oil cannot be used normally.

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 contact of the silver sensitive circuit inside the booster system or other problems.

4. The tire pressure of the car is too low.

If the tire pressure of the car is too low, it will also cause the steering wheel to become heavier, and in severe cases, it may even burst due to insufficient tire pressure. Therefore, it is recommended that when the steering wheel becomes heavier, first check the tire pressure and steering power oil.
