hydraulic engine

Improper thread connection: If the thread connection does not have the correct tightening force and torque, it may cause the screw to be easy to loosen and break. Thread aging: If the thread connection is used for too long, it will cause the thread to age and wear, resulting in loose and broken screws.

I just changed the hydraulic pump engine, and it's a little heavy. Check whether there is any abnormal noise, and learn to distinguish the abnormal noise that belongs to the reasonable noise. It is difficult for ordinary car owners to distinguish which are faulty abnormal noises and which are reasonable abnormal noises.When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.

A hydraulic engine refers to an engine that uses liquid as the working medium and uses the pressure energy of liquid to transmit power. Engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Sterling engines, steam engines, etc.), electric motors, etc.

What is the function of hydraulic suspension of automobile engine

Hydraulic suspension is an automobile part used for shock absorption, and the interior of the suspension is full of oil. The process of this system is to replace ordinary shock absorbers with oil cylinders, and the height of the body can be increased or decreased by increasing or decreasing hydraulic oil., that is, automatically adjust the ground clearance according to the speed and road conditions, so as to improve the smoothness and control stability of the car.

Its main functions are: supporting. The most basic function of the suspension system is to support the powertrain. When designing the suspension, it is necessary to ensure that the powertrain of the automobile is in a reasonable position and that the whole suspension system has a sufficient service life. Limiting effect.

Improve driving comfort: Double hydraulic suspension can reduce body bumps and vibration, providing a smoother driving experience. Improve vehicle stability: Double hydraulic suspension can make the vehicle more stable when driving at high speed and reduce the body shaking caused by uneven road surface.

Suspension is an automobile powertrain used to reduce and control the transmission of engine vibration and play a supporting role. It is applied to the current automotiveIn the industry, the widely used suspension is divided into traditional pure rubber suspension and hydraulic suspension with good dynamic and static performance.

When the natural frequency of the vibration is equivalent to the inherent vibration of a certain order of the car, larger vibration and noise will be formed. The powertrain suspension is the connecting part between the engine and the car body. Its main function is to attenuate the low-frequency vibration of the engine and suppress the high-frequency noise generated in the cab.

The installation system is part of connecting the powertrain and the car body. The key function of the suspension system is to support the powertrain, shorten the relationship between the total dynamic vibration and the whole vehicle, and limit the total dynamic vibration, which plays a very important role in the NVH performance of the whole vehicle.

What are the advantages of the engine hydraulic column?

The biggest feature of the hydraulic column is that it is stretchable. Therefore, the hydraulic column engine does not need to adjust the valve gap. This is much less noisy than other engines that need to adjust the valve gap, but the structure is complex and the oil pressure is strict.

The hydraulic lever can achieve fast response, which provides higher performance for the car engine. In addition, compared with ordinary steel boltsThe stroke should be smaller and the volume occupied should be smaller, so the internal structure of the car engine can be more compact, so as to improve the efficiency and power output of the engine.

3 eliminates the noise, impact, etc. caused by the valve gap, and reduces the friction wear of the cam surface and the top of the column. The hydraulic column of the automobile is made of quenchable cast iron, which is a precision coupling part. The structure is relatively complex, and the processing accuracy requirements are high.

The hydraulic bar uses the pressure of the engine lubricating oil to adjust its own length to compensate for the reduction of the valve gap in the valve transmission mechanism caused by thermal expansion, wear and other factors to a minimum. The hydraulic support rod can make the engine gas distribution mechanism maintain good airtightness during the working process and ensure the smooth operation of the engine.
