The role of the drive shaft:
1, the drive shaft is an important part of the transmission of power in the automobile transmission system, its role is to transfer the power of the engine to the wheel with the gearbox and the drive axle, so that the car generates driving force;
2, the use of the drive shaft: the special car drive shaft is mainly used in tank trucks, refueling trucks, sprinklers, suction trucks, suction trucks, fire trucks, high-pressure cleaning vehicles, road wreckers, aerial work vehicles, garbage trucks and other models;
3, the drive shaft is a high speed, less support of the rotating body, so its dynamic balance is crucial. Generally, the drive shaft should be tested for action balance before leaving the factory, and adjusted on the balancing machine.

1. The full name is exhaust gas recirculation valve/pressure converter valve.
2. The EGR valve is a very important and key component in the exhaust gas recirculation device.
3. The EGR valve (egr solenoid valve) is a mechatronic product installed on the diesel engine to control the amount of exhaust gas recirculation fed back to the intake system.

The role of the automotive egr vacuum solenoid:
1. Control the amount of exhaust gas entering the intake manifold so that a certain amount of exhaust gas flows into the intake manifold for recirculation.
2. Improve the working efficiency of the engine, improve the combustion environment, reduce the burden on the engine, effectively reduce the emission of NO compounds, reduce knocking, and prolong the service life of each component.
3. It can reduce the emission of nitrogen oxide (NOX) in exhaust gas.

Engine support pad broken common manifestations:
1, driving under the resistance of large torque, there will be a phenomenon of shrugging the car, reversing will also appear in the car, must increase the throttle can be solved;
2, start or open the air conditioning refrigeration engine shaking is very large, high-speed driving steering wheel vibration is obvious, while the acceleration and brake pedal also have a shock;
3, the second or third gear acceleration, often hear the sound of rubber rubber friction;
4. When the engine foot glue is found to have the above problems, it can be determined that the foot glue has been damaged, please replace it in time. Without effective shock absorption and support of the engine, some components will be damaged, which will affect the performance of the engine, not only the operation jitter, but also the phenomenon of unstable shaking of the engine.

When the car is running, it uses various oils and air. These oils and air are not pure, and contain more or less impurities. And these impurities will increase the wear and tear of the car and shorten the service life of the car, so these impurities must be filtered out, and there are various filtering devices, such as air filters, oil filters, gasoline filters and so on. Today we will talk about the function and replacement cycle of these filters on the car.

Oil filter
There is no doubt that the oil filter is the most important filter in the car, also known as the "kidney of the engine". The function of engine oil is mainly to filter most of the impurities in the engine oil, keep the engine oil clean and prolong the service life of the engine.

Steel plate bushing is a kind of accessories used outside mechanical parts to achieve sealing, wear protection and other functions, which refers to the ring sleeve that plays the role of liner. It can be used in many different cars, including those with factory suspension systems. The role of the bushing is to absorb the impact of the collision and protect the brake disc from dust and debris. In addition, the steel plate bushing can also be adjusted to work properly, but it is highly recommended that you let a professional perform this task to ensure safety. Now, you can find many different designs of bushings that you can purchase and install into your car. However, there are also some manufactured to improve the performance of the brake. This means that it will be harder for you to put pressure on the brakes while driving, but easier to maintain brake performance.

There are generally three places for the rubber dust cover on the steering machine:
1. It is between the steering gear, the car body and the floor. The steering boot here generally plays the role of shock absorption, noise reduction and dust prevention;
2. It is the part connecting the end of the tie rod of the steering machine and the rocker arm of the wheel, which is in the shape of a leather bowl. The steering rubber boot here is filled with grease to prevent atmospheric dust from entering the ball pin housing and storing grease;
3. It is on the steering machine, one end is fixed on the cylinder of the steering machine with a cable tie, and the other end is fixed on the tie rod with a metal clip. This power steering boot is mainly to prevent muddy water, oil and dust from entering the steering machine. Steering heavy and dead.

The car cannot run if the tie rod end is broken. The tie rod end ball joint of the car is also called a universal joint. It is a very important part of the car. It is a mechanical structure that uses a spherical connection to transmit power to different shafts. The steering mechanism provides multi-angle rotation, thereby reducing vibration and achieving smooth steering.

The ball joint of the steering series is an indispensable part for transmitting the power of the steering wheel to the tires, and supports the "turning" function among the three basic functions of the car "driving", "turning" and "stopping". The ball joint of the suspension series is one of the parts that maintains the correct direction of the tire and improves the driving stability, and contributes significantly to the realization of modern comfortable and safe driving.

The role of the power steering pump pulley is to drive the water pump to run. Once the power steering pulley breaks, it will affect driving, and the steering pulley will rotate heavily, which will pose a safety hazard during driving, so it needs to be replaced in time.
