The car feels particularly heavy when cornering?

It may be that the steering gear and steering linkage mechanism are not in good condition, or there is a problem with the tires, or it may be that the hydraulic power steering system is failing.

Looking at the manual, some vehicles will become heavy when the electronic power steering is at high speed. I don't know if that's the case. Otherwise, go check it out.

Check that the tires are not full of gas, it should be that they are low on gas.

Mainly due to resistance during turning.

Check whether the booster oil should be changed, the general direction machine booster oil 30,000 kilometers to change once, if it is an electric booster, you have to see if he is working when playing the direction, if there is no booster device to check the direction machine.

First of all, we must know whether the direction of the car has a power assist function, if there is, check whether the power assist oil should be changed, the general direction machine power assist oil 30,000 kilometers to change once, if it is an electric power assist, you have to see if he is working when playing the direction, if there is no power assist device, check the direction machine, or whether the steering mechanism is loose and deformed.

The following is illustrated by the situation where the car is driving in a straight line and is not electronically assisted.

When the car turns, the center of gravity of the car moves forward and moves in the opposite direction of the steering wheel; At the same time, the car is affected by centrifugal force, and the car has a tendency to roll over, and the weight is also transferred to the front and rear wheel side; In the above case, the weight on one side of the front wheel must increase in proportion to the weight of the whole vehicle, and the front tire is compressed, so that the friction between it and the ground increases, resulting in a heavier feeling when hitting the direction.

There is also a case where when the turning speed is fast, it is heavier than hitting the steering wheel at a slow corner.

The hydraulic system lacks oil and the afterburner is insufficient when steering; The oil pump dynamic cylinder or distribution valve is worn, the sealing ring is damaged, the internal leakage is serious, and the pressure is insufficient; There is air in the hydraulic system; Poor working of the road drive oil pump device version (too loose belt or poor gear transmission); Clogged filters, leaking or clogged oil supply line joints, poor oil supply; The safety valve is leaking oil or the spring is too soft and the pressure is insufficient.

What is the reason for the heavy steering of the car?

Causes and elimination methods of heavy steering of automobiles Troubleshooting check the front tire pressure check whether the car is overloaded or the front is overloaded, whether the front tire pressure is too low, if the tire pressure is low, it should be inflated to reach the specified value to support the front axle, and turn the steering wheel by hand to test. If you feel that the steering wheel is light, it means that the front axle or frame is deformed, the front wheel alignment is inaccurate, etc., and the calibration should be checked and calibrated. Remove the steering rocker arm and turn the steering wheel for testing.

If you feel that the steering is light, it means that the fault is in the steering transmission mechanism to pull the front wheel test left and right by hand, check the fit between the steering knuckle kingpin and the bushing, if the wheel is more laborious, it means that the steering knuckle kingpin is poorly lubricated or the fitting clearance is too small, the steering knuckle thrust bearing should be filled with grease or adjusted to adjust the fitting clearance, and if the bearing is short of oil or damaged, it should be replaced.

The steering wheel suddenly becomes heavy, if you suddenly find that there is obvious resistance in the direction of rotation while driving, and the steering wheel cannot automatically return after turning, it may be that there is an air leak on one side of the front wheel, if it is hydraulic assistance, it may be that there is a problem with the booster oil, if it is electric assistance, it may be that the fuse is burned out or there is a short circuit in other lines.

If the vehicle feels heavy and laborious while steering, it may be due to a malfunction in the steering system, and the driver is advised to check the steering system.

Commonly used automotive steering systems include electric power steering systems, electro-hydraulic steering systems, and mechanical hydraulic steering systems. Electric power steering is not a hydraulic mechanism, this steering system relies on an electric motor to provide steering. Electronic and Mechanical Hydraulic Steering System A hydraulic steering system is a hydraulic mechanism, both of which use steering oil.

Electronic & Mechanical Hydraulic Steering SystemThe hydraulic steering system has steered the power pump, which is connected to the engine by a belt, and the engine also drives the power steering pump to run while the engine is running. If there is a problem with the belt, it will affect the work of the steering power pump and the steering handle will become heavier.

The specific cause analysis may be as follows:

1.Low on fuel. Fuel is the main driving force that drives us**, so when we run low on fuel, it's natural for us to struggle to drive our cars, let alone steer.

2.The steering machine or steering column bearing is damaged, causing serious damage. This is a type of mechanical damage and the bearing must be replaced.

3.The tie rod ball joint has insufficient oil supply or damage, resulting in serious damage. If damaged, the ball pin must be replaced.

4.Before the tire pressure is insufficient, the steering wheel is heavy. Tire pressure should be checked regularly and wheel tires should be inflated as specified.

5.The steering pinion and rack joint clearance is too small, resulting in overweight tires. Ask a professional maintenance technician to adjust the pinion preload.

Therefore, when using the hydraulic steering system of automobiles, the steering power pump belt should be checked frequently, and the steering oil should be changed regularly. If a car with an electric power steering system feels heavy, the system needs to be updated or reset. If the power steering pump of a car using a hydraulic steering system breaks the belt during driving, the driver will immediately lose steering, which is more dangerous.

I believe that after passing the above analysis, drivers must have an understanding of their own car conditions.

It may be that there is a problem with the power steering unit, so the vehicle feels heavy and laborious when steering.

It may be due to the failure of the power assist pump after steering, the oil leakage of the rotary valve, or the drive conversion of the power assist pump.

Because the wheelbase of the car was too small, the steering system failed, and the electro-hydraulic system did not work, so it felt heavy and laborious.

The four reasons for the heavy steering of the car are as follows: 1. Insufficient fuel to help the attack; 2. The bearing of the steering gear or steering column is damaged; 3. Lack of oil or damage to the ball joint pin of the steering tie rod; 4. Insufficient tire pressure on the front tires. Heavy steering in the car will increase the physical exertion of the driver, which needs to be solved as soon as possible.

The steering system is a series of devices used to change and maintain the direction of the car, which plays an important role in the safe driving of the car. Therefore, if the steering system fails, it must be paid attention to, and it must be checked and repaired in time.

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 turn and change direction.

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 with the required 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. Insufficient oil to help Paivo; 2. The bearing of the steering gear or steering column is damaged; 3. Lack of oil or damage to the ball joint pin of the steering tie rod; 4. Insufficient tire pressure on the front tires. The heavy steering of the car will cause the physical consumption of the driver to increase, and it is necessary to untie the chain as soon as possible.

It may be that there is less power assist oil in the steering engine.

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.

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 exciting. 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 booster system, or rule out whether there is no lead leakage and damage to the inlet seal.

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.You will know if you go to run a ring road, you don't dare to run on the narrow road around the mountain road, you can only drive slowly. Because the steering reaction is slow, you will panic. Steering sensitivity is always half a beat slower.

2.The large virtual position (not the loose virtual position, but the virtual position set by the adjustment) is suitable for high-speed straight driving, and it is easy to keep the lane; The virtual position is small, the response is sensitive, the steering is precise, suitable for running mountain roads, and low speed.

3.Variable steering system, which can be set artificially; However, the degree of fineness of tuning depends on the level of the commissioning engineer, and some cars are still high-quality even if they do not have this system. For example, cheap and fun, Peugeot 307, Polo.

4.The full-frame subframe is less accurate than the frame of the Yuanbaoliang, mainly because of the overall layout of the full-frame type, which makes the steering accuracy more difficult to adjust.

5.Try the same car as yours, if it's the same it's a design problem, if it's different, it's your chassis inclination offset.

Look at the direction of the power tension belt is loose or not Check the direction of the hydraulic power booster oil is not less, and check the ball heads of the suspension system If it is all right, then change the direction of the power pump

Check the suspension and do a four-wheel alignment.

There are four main reasons for the heavy steering of the car: 1. Lack of booster oil: The lack of booster oil will directly lead to heavier direction, because the booster pump needs sufficient oil to push the piston to bring assistance.

When the vehicle has a shortage of booster oil, it is necessary to check whether there is oil leakage in the pipeline, if there is no oil leakage, check whether the oil is dirty, whether the pipeline is blocked, etc., and then repair it according to the specific problem. 2. Slippage or breakage of the belt of the booster pump: the power of the booster pump needs to be transmitted by the belt, and if the belt slips, it will cause the booster pump to fail to reach the speed standard when working, so that the booster will become sinking; If the belt is broken, the booster pump will directly lose its working power source, and the vehicle will have a complete failure without assistance.

When the above situation occurs, only the belt of the booster pump needs to be replaced. 3. Motor damage: The motor is the last and most important link to provide steering assistance, and its damage will cause the vehicle to become heavier or directly without assistance.

During maintenance, it is necessary not only to check whether the circuit is normal, but also to check whether the sensors, control units, fuses, relays and other components are normal. 4. Low tire pressure on the front wheel: low tire pressure will increase the contact area between the tire and the ground, which also means that the friction resistance during driving or steering will increase.

When handling, the first thing to check is whether the tire is leaking, and if there is no air leak, you can make up the air pressure.
