What s the deal with parking and hitting the steering wheel and refueling lightly?

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, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

1.The in-situ direction is heavier, and the high-speed direction becomes lighter. This is normal for hydraulically assisted vehicles.

The vehicle is not moving, and the friction that the wheels need to overcome in order to turn is the greatest, so it is normal to be a little heavier. In the past, the car did not have directional assistance, and it took a lot of force to move if it stood still, and it would be much lighter to drive. Why does the direction of high speed become lighter?

It is formed by the combination of several reasons. First of all, the engine speed is fast, and the speed of the booster pump is also fast, so the power is relatively 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, so that the pressure of the wheels on the ground is reduced, and the friction is also reduced, so the direction rotation will be lighter.

This phenomenon is particularly obvious in hydraulically assisted cars, and now many electronically assisted cars will add a function, when the speed is high, the direction will be automatically weighted to reduce the feeling of light and floating of the vehicle.

2.Originally, the power was relatively light, but the vehicle became heavier after a long time. This is mostly due to the fact that the power steering oil has reached the end of its life and it is time to replace it.

Usually, the direction is relatively light, because there is a boost, as we turn the direction, the power system helps us to exert ourselves. The transmission of this force is to establish pressure on the booster oil through the rotation of the booster oil and the booster pump to push the rack in the direction machine to move. If the booster oil deteriorates, it will not be able to build up enough pressure, and the force transmission will become smaller or uneven, causing us to hit in a heavier direction.

Generally, the booster oil should be replaced in three years or 60,000 kilometers, and after deterioration, it will not only affect the transmission of influence, but also have an impact on the life of the booster pump and steering machine. If it is an electronically assisted vehicle, there is no need to think about oil changes.

Hello! It's a fault, it's your booster pump that only works at high speeds! Go to the repair point to replace the booster pump to solve the problem of steering sink!

It may be that there is a problem with the booster pump, and you go to the auto repair shop to check the condition of the car on the spot.
