Correct use and maintenance of the automotive hydraulic power steering system

1. Steering assistance system maintenance is the maintenance of the steering assistance system of the vehicle.The maintenance of the steering assistance system requires regular inspection of the use of steering assistance oil, booster pump, booster pump belt and other accessories. Add booster oil regularly and check whether the accessories are good or bad.

2. During maintenance, check the tightness of the steering pump belt to see if there is any breakage. If there is a break, replace it in time. Elasticity with your fingers should be about 1cm. Regularly check whether the pipe joints of the hydraulic system are leaking oil. Hydraulic oil pipes should try to avoid friction with other parts to prevent damage to the air intake.

3. Today, our car side will share the good use and maintenance of the hydraulic power steering system with our friends. Procedure Regular maintenance of whether the steering hydraulic oil is missing. If it is missing, it should be supplemented immediately. At the same time, clean the hydraulic oil cup and filter element regularly to prevent the hydraulic oil from getting dirty or deteriorated. It is recommended to change the hydraulic oil every 3,000 kilometers.

4. 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.

5. In addition, the mechanical hydraulic power steering system is composed of a hydraulic pump, pipeline and cylinder. In order to maintain the pressure, whether the steering assistance is required, the system always needs to be in working condition, which is also a reason for resource consumption. Most economical cars use a large number of mechanical and hydraulic power systems.

How does the automobile steering hydraulic system work?

1. 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.

2. The hydraulic power steering system is the steering system that controls the car. The most basic function is steering to ensure that the car can drive according to the driver's wishes. The hydraulic power steering system is mainly composed of mechanical parts and hydraulic power devices.

3. Today, I would like to share with you the working principle of the steering system to improve your understanding of automobile knowledge. In the hydraulic power steering system, the steering power is determined by the pressure acting on the piston of the steering power cylinder. When the steering force is large, the hydraulic pressure will also increase accordingly.

4. In short, the hydraulic power steering system is a key part of the car chassis, which plays a crucial role in ensuring the safety and comfort of the driver's operation.Although it has some shortcomings and problems, as long as proper maintenance and repair is carried out, the normal operation of the system can be ensured.

5. Working principle: in the middle position (when the steering wheel does not turn). The oil from the oil pump is returned to the fuel tank through the inside of the steering device.

What is an automotive hydraulic system

1. The control system composed of hydraulic technology is called a 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.

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

3. 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.

Is the hydraulic oil of the car the same as that of the forklift?

Belongs to. The return oil of the forklift gearbox is the oil pumped from the gears in the hydraulic system. The transmission oil is also a hydraulic oil. A forklift is an industrial handling vehicle, which refers to the loading, unloading and stacking of pallet goods.And all kinds of wheeled handling vehicles for short-distance transportation operations, the International Organization for Standardization ISO/TC110 is called industrial vehicles.

The fuel refueling port is generally exposed on the inside of the car; the hydraulic oil refueling port is generally on the outside of the car, some exposed and some covered; the fuel oil refueling port is at the top of the engine: the fluid transmission oil refueling port is in the upper part of the gearbox; the brake oil cup is found along the brake master pump, generally above the clutch (slight movement) pedal.

The cleanliness requirements of hydraulic oil are relatively high. There are several layers of filtration devices in the system. The filtration of some systems is very strict, especially for foreign products. Mechanical oil is now called full-loss system oil. Because there are many types of machinery and equipment, they also play different roles, so there are also many varieties of lubricating oil required.

Question 9:What kind of hydraulic oil should be added to the automatic gear forklift? The hydraulic oil is the same, but the wave tank oil is different. Question 10: The label and quantity of hydraulic oil used by the forklift. For this is still necessary to ask the engineer of the forklift. Generally, it will be marked.

Most of them are hydraulic oil, but the brand signal specifications are different, which is mainly related to viscosity and temperature.
