What is automotive hydraulic system

Control composed of hydraulic technology The system is called the hydraulic control system. Hydraulic control usually includes hydraulic open-loop control and hydraulic closed-loop control. Hydraulic closed-loop control is also called hydraulic servo control, which constitutes a hydraulic servo system, usually including an electrical hydraulic servo system and a mechanical hydraulic servo system.

The hydraulic pressure of a car increases the force by changing the pressure. Cars must be equipped with hydraulic systems, such as clutch hydraulic devices, steering hydraulic devices (some cars have adopted electronic assistance), brake hydraulic devices, etc., as well as hydraulic push devices used by dump trucks, cranes, etc.

The hydraulic system consists of two parts: signal control and hydraulic power. The signal control part is used to drive the control valve action in the hydraulic power part. The hydraulic power part is represented by a circuit diagram to show the interrelationship between different functional components.

Automotive hydraulic brake system refers to the brake system. The working principle of the brake system is to create a huge friction force and convert the kinetic energy of the vehicle into heat energy.

Brake fluid brake fluid is a liquid medium that transmits brake pressure in a hydraulic brake system. There are synthetic type and mineral oil type, which are divided into four levels: DOTDOTDOT1. DOTDOT4 mineral oil brake fluid is commonly used in cars. The function of the brake fluid control oil pipe is to transmit the brake fluid in the brake system.

The automobile steering hydraulic system is an early power steering system.The hydraulic power steering system is composed of a hydraulic pump, an oil pipe, a pressure flow control valve body, a V-shaped transmission belt, a storage tank and other components. When the vehicle turns, through the intervention of the auxiliary system, the problem of heavy steering is solved and some of the driver's labor force is released.

Principle of automotive hydraulic brake system

1. Working principle of hydraulic brake, introduction to hydraulic brake: working principle It is composed of brake yco, excitation coil, spring, brake disc, armature, spline sleeve, mounting screw, etc. . The brake is installed at the rear end of the equipment flange (or motor). Connect the spline sleeve of the transmission shaft and the brake disc.

2. Automobile hydraulic brake system refers to the brake system. The working principle of the brake system is to create a huge friction force and convert the kinetic energy of the vehicle into heat energy.

3. The working principle of the hydraulic brake system; When the driver steps on the brake pedal, under the action of the vacuum booster, the brake fluid of the total mercury of the brake enters the brake before and after pressurization. Then, the wheel brake works, generates braking force, and makes the car slow down or even stop.

4. Automobile hydraulic brake system refers to the brake system. The working principle of the brake system is to create a huge friction force and convert the kinetic energy of the vehicle into thermal energy. As we all know, energy is neither generated nor disappearing out of thin air. It can only be converted from one form to another, or from an object. Move to another object and transform.

What are the faults and maintenance methods of automobile hydraulic power steering?

1. The common faults of the hydraulic steering system are heavy steering; the steering wheel deviates; the steering wheel rotates and cannot return to the idle position; the steering wheel shakes seriously; and the steering wheel rotates without a dead point. Turning to heavy fault analysis, the main flash is that there is not enough pressure oil to supply the steering or sufficient mechanical failure.

2. The solution to the fault of the power steering is that there is a strange sound when steering. The abnormal sound when steering is generally the mechanical part. For example, the main pin and bushing damage the column thrust bearing damage, etc. When checking, the direction can be left and right, and the part of the sound can be observed to disassemble and inspect the oil leakage of the steering machine. The oil leakage part of the steering machine is rotated. Cover the side end of the machine.

3. What is the fake label like? Car Master Rabbit 2023-06-17 · Adopted by more than 233 usersTA's answer, follow, expand all, use and maintenance of hydraulic power steering system, heavy steering is mostly caused by the ineffectiveness of the steering hydraulic assistance system, which has nothing to do with the mechanical part of steering.

What are the hydraulic transmissions used in automobiles

1. The application of hydraulic transmission on vehicles: to make the vehicle have good adaptability. A hydraulic torque converter is installed behind the engine, and the torque on the torque converter output shaft is comparable to the rotation of the engine. The moment increases several times, and the rotation speed can be reduced to zero.

2. (3) Control component valve (functioning to control pressure, direction and flow rate) (4) Auxiliary components Hydraulic oil tank, filter, pipeline, etc. (5) Working medium Hydraulic oil. The combination of hydraulic transmission system uses hydraulic force and machinery to transmit power.

3. The main components of the hydraulic transmission device are as follows: the brake master cylinder The main cylinder can convert the mechanical force input by the brake pedal into hydraulic pressure. Most of the brake cylinders are made of cast iron or alloy, some of which are integrated with the oil storage chamber to form a whole main cylinder. Others are separated from each other and then connected by an oil pipe, which is a separate main cylinder.

The oil leakage of the automobile hydraulic brake system causes the automobile brake to run out of control and become a traffic accident, resulting in the risk of casualties...

1. The risk factor of the oil leakage of the automobile brake system causing the car to lose control and the death of people is a super-large traffic accident.

2. The third type, oil sealFailure This is the main reason for oil leakage in cars. Simply put, oil seal is a mechanical original used to seal oil.

3. Risk factors, also known as risk events, refer to the conditions that cause and promote the occurrence of risk accidents, and the increase and expansion of losses when risk accidents occur. It is the potential cause of the accident and the indirect and intrinsic cause of damage.

4. Reason: the aging of the sealing ring and the deterioration of the lubricating oil cause the temperature of the cylinder to rise abnormally, which promotes the aging of the sealing ring. Solution: It needs to be analyzed according to the sealing ring or cylinder and other problems.

Automotive hydraulic separation Advantages of the gate

Advantages of automobile hydraulic clutch: the clutch is lighter, and there will be no phenomenon of wire jamming. The slight jitter of the separation bearing will not be transmitted to the clutch pedal after the filtration of hydraulic oil. There is no wire in the hydraulic clutch, only the pipeline and the sub-pump master pump. Because the clutch of the pull wire is easy to break or the pull wire rust, resulting in the weight of the clutch.

Advantages of hydraulic clutch: 1. Light and comfortable operation. 2. The friction resistance is small, and long-term operation will not significantly increase the pedal force.To put it simply, you have seen the principle of the wire brake of a bicycle.

Friction clutch uses the friction between the junction components to achieve the purpose of transmission. The advantages are stable clutching and closing, soft and impact-free, which can be sleased and closed at a high speed difference. When overloaded, it has a safety protection effect and has high adaptability.
