The steering wheel has sunk recently, what to do, what to do if the steering wheel sinks

1. Low tire pressure.

The four-wheel air pressure should be 225kpa, and the low air pressure will cause the friction area between the tire and the ground to be too large, which will cause the steering wheel to increase the force;

2. Toe-in and camber angles are beyond the allowable range.

Excessive toe angles of the two front wheels and inverted casters of the kingpin are beyond the allowable range, which increases the damage to the tires and also causes the steering wheel to turn more forcefully.

Third, the internal adjustment of the steering machine is too tight.

If the internal structure of the steering machine is too tight, it will also cause the steering wheel to be heavy, and it needs to be checked in a professional place.

Fourth, check the electronic power assist system.

The steering power assist is electronically assisted, and the fuse is checked for burn-out, and whether the line is open or short to the ground.

If these problems are present, they will also cause the steering wheel to be heavy.

5. Carry out four-wheel alignment inspection.

After the car travels a certain mileage, the front wheel kingpin camber, kingpin camber, inclination and front wheel toe-in, rear wheel.

Wheel camber and rear toe-in deviations can also cause the steering wheel to sink.

Generally, after the above inspection and adjustment of the problematic items, the problem of steering wheel sinking can be solved.

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 reason why the steering wheel of a car is heavy:

1. 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, and if there is no shortage of oil, check whether the booster pump belt is too loose, and if it is too loose, the belt needs to be tightened, and whether the oil is too dirty to cause poor fluidity, which is generally replaced once every 2 years or 60,000 kilometers.

2. If it is electronically assisted, check whether the fuse is burned out, and whether the line is open or short circuited to the ground.

3. Check the tire pressure, air leakage will also cause the direction to become heavier, so you need to inflate.

It is an electric power boost, and repeatedly turning the steering wheel in situ or at low speed has a great load on the power assist system, which is easy to protect the steering machine from high temperature, resulting in heavy steering, and can be restored after heat dissipation, which is a normal phenomenon.

The following parts need to be checked for heavy steering wheel: collapse 1, check whether the hydraulic oil is sufficient; 2. Check whether the tire pressure is sufficient; 3. Check whether the hydraulic oil circuit is blocked to enter the space, etc.; 4. Check whether the steering booster is damaged; 5. These are the reasons why the steering wheel is heavily emptied.
