What is the use of the car's assistance system?

1. Power steering system,As the name implies, it is to assist the driver in adjusting the direction of the car and reduce the intensity of the driver's force on the steering wheel. Of course, the power steering system also plays a certain role in the safety and economy of the car.

2. The function of the automobile steering booster pump is to reduce the driver's operation intensity, improve the maneuverability of the whole vehicle, ensure the safety of the steering system, and ensure the driver's steering feel when the vehicle is driving at high speed.

3. At low speed, the electric power steering system can provide greater steering power and steering portability of the car.

4. The direction assistance of a car refers to the force that uses external power to produce steering assistance in order to reduce the driver's operating force on the steering wheel, which is called direction assistance. Three types of power steering systems are configured: mechanical hydraulic power steering system.Electric hydraulic power steering system. Electric power steering system.

5. The electric power steering system is a power steering system that directly relies on the motor to provide auxiliary torque. The electric power steering system is the development direction of the automobile steering system. The electric power steering system provides the driver with auxiliary steering operation.

6. The function of the car vacuum booster is to use vacuum (negative pressure) to increase the force exerted by the driver on the pedal. The vacuum booster is generally located between the brake pedal and the brake master cylinder. In order to facilitate installation, it is usually synthesized into a component with the master cylinder, and part of the master cylinder goes deep into the vacuum booster housing.

How does the car steering booster pump work?

The function of the booster pump is to generate high pressure in the steering system, and the high-pressure oil pipe is responsible for transmitting pressure from the booster pump to the oil volume control valve in the steering device. The oil regulating valve is installed on the steering shell, and there is a small gear at the end, which is used to cooperate with the rack in the steering.

The function of the automobile steering booster pump is to reduce the driver's operation intensity, improve the maneuverability of the whole vehicle, ensure the safety of the steering system, and ensure the driver's steering feel when the vehicle is driving at high speed.

The working principle of the power steering pump is: when the pump is working, the slide valve has a certain opening degree, so that the flow rate meets the specified requirements. The excess flow rate is returned to the oil absorption chamber of the pump.

What are the classifications and characteristics of power steering?

(2) One is an electronic hydraulic power steering system; (3) The other is an electric power steering system. Mechanical hydraulic power steering system Mechanical hydraulic power steering system is generally composed of hydraulic pump, oil pipe, pressure flow control valve body, V-type transmission belt, oil storage tank and other components.

These three types of power steering can be regarded as cascade development, and the purpose of research and development is to be convenient.

Hydraulic power steering system.(Hydraulic power steering) The hydraulic power steering system has a history of half a century. It can be said that the technology is very mature, so it is widely used. The hydraulic power steering system is composed of a hydraulic part and a mechanical part.

The hydraulic assistance system software selects a foot-mounted hydraulic assistance pump driven by the engine belt to complete the actual effect of amuth assistance. This kind of assistance system software is relatively accurate. After a long period of deposition, the technical level is very perfect and stable, and the cost is also very low.

The types of power assistance include electronic hydraulic assistance and mechanical hydraulic assistance. The differences between the two are as follows: different components Electronic hydraulic assistance: electronic hydraulic assistance includes oil storage tank, power steering control unit, electric pump, steering machine, power steering sensor, etc., including power steering control unit and electric pump It is a whole structure.

If it is not turned, the system will not work and will be in a dormant state waiting for the call. Due to the working characteristics of electric power steering, you will feel that driving such a car has a better sense of direction and is more stable at high speed. As the saying goes, the direction does not float. And because it doesn't work when it doesn't turn, it also saves energy to some extent.

What is the function and principle of the automobile steering booster pump?

The function of the booster pump is to generate high pressure in the steering system, and the high-pressure oil pipe is responsible for transmitting pressure from the booster pump to the oil volume control valve in the steering device. The oil regulating valve is installed on the steering shell, and there is a small gear at the end, which is used to cooperate with the rack in the steering.

The booster pump isThe power source of the power steering system is that when the engine is working, the steering booster pump is assisted by the crankshaft pulley driven by the belt.

Power steering pump is an important part of the automobile power transmission system. Its function is to provide hydraulic assistance for the steering machine and reduce the steering force during steering. In a car, the steering machine is the part used to control the wheel steering, and the driver needs to forcefully turn the steering wheel so that the steering machine can be turned.
