Can the car electronic power steering motor be repaired if it is broken

There are three situations that will occur when the steering gear of the car is broken:

1. There will be abnormal sound when you hit the steering wheel in place, whether it is in place or when the speed does not exceed 20 kilometers per hour.

2. The turning steering wheel is very loose or the steering wheel is very heavy and very difficult.

3. The typical power booster pump failure leads to difficulty in direction rotation, and the direction of rotation will be abnormally heavy during driving.

At present, the steering system configured on the car can be roughly divided into mechanical steering, mechanical hydraulic power steering system, electro-hydraulic power steering system and electric power steering system.

Most of the new models are equipped with electro-hydraulic or electric power assist systems, while mechanical steering gears have been phased out.

Maintenance precautions for mechanical steering machines:

1. When driving on potholes and uneven roads, slow down and slow down to reduce the load on the steering machine.

2. Always check the protective sleeves on both sides of the steering machine and the protective sleeves connected to the universal cross shaft on the upper part of the steering machine. Breakage of the sheath is the most important factor that causes early wear and damage to the steering machine.

After the sheath is damaged, water, dust and sand will enter the inside of the steering machine through the damaged place, destroying the grease oil film of the rack and pinion, resulting in rust and abnormal wear inside the steering machine.

3. Due to the use of grease, it will gradually become dirty and deteriorate, so that the lubrication capacity will decrease; At the same time, the material under wear will gradually increase, and the abrasive wear phenomenon will become heavier and heavier, which will aggravate the wear of the steering machine.

4. The use conditions of the steering machine are harsh and the load is large, so special grease must be used.

5. The clearance will gradually increase in use, if the clearance of the steering wheel is too large, the steering machine must be inspected, if the rack and pinion are abnormally worn, the steering machine assembly must be replaced.

6. Do not carry out the maintenance and maintenance of the steering machine in the roadside shop with poor equipment and low technical level. If the steering machine is not adjusted properly, it will cause jamming, endangering driving and personal safety.

Analysis of hydraulic power assist systems.

The structure of this type of booster system is shown in the figure below, which is mainly composed of oil return pipe, oil inlet pipe, oil outlet pipe, steering device assembly (including steering control valve), booster liquid oil tank, steering power pump, etc. The hydraulic power assist system is characterized by low sound when working, short response time of lag, and better absorption of road impact from different road conditions.

As shown in the figure below, when we play the steering wheel, the steering control valve also rotates, opening and closing the channel of the oil channel in the internal structure control steering gear, so there will be different pressure differences on the power cylinder in the steering gear.

At the same time, the power piston is pushed to the left or right, so that the effect of power is produced. The power then transmits the torque to the wheels through the steering tie rod so that the left and right wheels have the correct steering relationship.

Yes, if the steering machine is broken, it must be repaired, it is best to repair it, and it is best to replace the assembly parts directly if it cannot be repaired, and it is best to replace the original parts, which is guaranteed, which directly affects driving safety. If the steering machine is broken, it may be difficult to steer, the steering power will fail (that is, there is no power assist, and the steering is too heavy when steering), the steering machine will be stuck and unable to turn (the direction cannot be turned directly, and it will be stuck), and the indirect will also lead to abnormal tire wear.

China's latest national standard "Terms and Definitions of Automobile and Trailer Types" (GB T 3730 1-2001) has the following definition of automobiles: non-track vehicles driven by power and with 4 or more wheels, mainly used for: carrying people and (or) goods; towing vehicles carrying people and/or goods; Special Purpose.

In 1680, the famous English scientist Newton.

The scheme of a jet car, using a nozzle to eject steam to propel the car, was conceived, but it was not made into a physical object.

Steam power. In 1769, the Frenchman N.J. Günyu built a three-wheeled automobile powered by steam from the combustion of coal gas.

However, the speed of this car is only 4 kilometers per hour, and it has to stop every 15 minutes to refuel the boiler, which is very troublesome. Later, the car crashed into a brick wall during a march and shattered the collision.

Can be repaired, but not very well, or a new insurance.

Solution 1: Can be repaired, but not very well or replaced with a new insurance solution 2: Generally the entire replacement.

If the motor of the electronic booster pump is broken, the most obvious symptom is that it will be very heavy when hitting the direction, and it will not move, and there is a fault light on the instrument. If it is an electronic booster, the impact of the broken motor is the direction of heavy.

Electric Power Steering (EPS) is a power steering system that directly relies on the electric motor to provide auxiliary torque, and the EPS system has many advantages over the traditional hydraulic power steering system HPS (Hydraulic Power Steering). EPS is mainly composed of torque sensor, vehicle speed sensor, electric motor, deceleration mechanism and electronic control unit (ECU).

Electric power steering is actually the direct output power of the motor to help you increase the power of the steering wheel. No more hydraulics.

So basically, most of the faults of electric power steering are related to poor contact. Whether it is a loose connector on the motor side that causes poor contact, or a loose connector on the direction sensor that causes poor contact, it can cause a failure of the electric power steering system.

Generally, the most common thing is that the amount of power is lost, that is, there is suddenly no power and the steering wheel becomes heavy.

The faults of the electric power steering system of the automobile are mainly as follows: (1) heavy steering: 1

Steering system: The power steering system contains a large amount of air, which causes the car to steer abnormally; 2.Hydraulic Hose:

There are foreign objects in the steering hydraulic pipeline that cause the flow control valve of the steering pump to be stuck; 3.Power steering system: The connection part of the power steering system is loose, resulting in the leakage of steering fluid; (2) There is abnormal sound in the steering

1.Steering system: The steering system is overloaded, resulting in excessive wear of the stator and rotor inside the steering pump, resulting in irregular movement of the oil in the pump and abnormal noise; 2.

Steering gear and steering pump: The installation of the steering gear and steering pump on the bracket is loose, the internal wear of the steering gear and the improper adjustment of gears and racks;

Questions.. The car's electronic direction assist is recovered after failure and restart, and there is a failure after driving for a while.

What is the reason for this.

1. There are foreign objects in the steering hydraulic pipeline that cause the flow control valve of the steering pump to be stuck. When there is a foreign object in the hydraulic line, the flow rate of the steering pump is high and low, which will cause false alarms in the steering power system; 2. False alarm of the sensor. If a sensor installed in the booster system fails, it will cause a false alarm of the booster system failure.

After restarting, the sensor is rechecked, and the false alarm may disappear; 3. Poor contact of electronic power supply line. Poor contact of the electronically assisted power cord will cause the steering system to fail, which may be restored after a restart. Symptoms of a broken electronic power assist module 1. The steering wheel has become significantly heavier.

Damage to the electronic power assist module will cause the electronic power assist to fail, and the steering wheel will become very difficult and the steering wheel will be extremely heavy; 2. The steering wheel sways from side to side. The electronic power assist module is the core of the control electronic power assist system, and when there is a problem with the power assist module, even if it is parked in place, the steering wheel may swing from side to side. 3. The steering wheel is light and heavy on one side.

There is a steering angle sensor in the electronic power assist module, which is an important part of the steering command to the power assist computer. If the steering angle sensor fails, it can cause the steering wheel to be different from side to side.

It is recommended to go to the repair shop or 4S shop for inspection.

The common faults of automotive electronic power steering include heavy steering, loose connections in the steering system, and abnormal steering noise.

The failure of electric power steering is basically related to poor contact, whether it is the loose connector at the motor end resulting in poor contact, or the loose connector of the direction sensor causing poor contact, it will cause the failure of the electric power steering system.

Analysis of electronic control and computer circuits. (Use multimeter, simulator, and analog ** signal to observe the changes before and after comparison; and the use of an oscilloscope to check the signal change relationship between each sensor and the computer).

It is recommended that you use a decoder to decode, find the fault, and then go to the repair shop to find a professional for you to detect and repair, I hope my help to you, hope.

Summary. Fault solution of electric power steering system: 1. When the coil in the torque sensor is damaged, or the torque sensor is damaged, it will cause the electric power steering indicator to light up.

In this case, it is recommended to replace the torque sensor. Of course, if it is a torque sensor in the steering machine, the steering machine assembly should be directly replaced at this time. 2. If the vehicle is powered off, or the battery is in the case of power loss, it will also cause the electric power steering indicator to light up.

It is recommended to start the vehicle in place first, then go left and right to kill the steering wheel, and after several consecutive operations, then go to drive the vehicle for about 30 to 50 kilometers, so that the electric power steering indicator will go out. 3. When the ABS sensor is dirty or damaged, it will cause the electric power steering indicator to light up. It is recommended to remove the ABS sensor first, clean up the dirt and dust on it, and then reinstall it.

If the electric power turn indicator is still on, the ABS sensor needs to be replaced.
