Automobile belt is a kind of rubber product. With the increase of their working time, automotive belts and related accessories will wear and aging. Therefore, it is very important to correctly and timely understand the use status of automobile belts. Next, let's talk about how to identify the damage of the belt from the sound and appearance.

1.Listen to the sound to see if it's good or bad

When the belt squeaks, it generally means that the friction coefficient of the belt surface is greatly reduced, and the belt has been excessively worn. If there is a noise when the vehicle is under load, you may wish to observe one of the transmission belts, and you will find that the resistance or elasticity of the automatic belt tensioner or the belt elastic wheel will increase abnormally. When you hear the belt rumbling, it means the belt is shaking. This situation occurs generally because the drive belt is too loose and stretched too long, or the belt tensioner and elastic wheel are damaged.

2. Watch the belt change

The belt becomes longer: The first step to check whether the belt is normal is to check the belt tension. Use your fingers to strongly press the middle of the belt pulley. If the pressure is about 10kg and the belt reduction is about 10mm, the belt tension is just right. If the amount is too large, it means that the belt tension is insufficient. The cause of the insufficient tension may be that the fastening wheel is loose, or the belt has become longer. If the belt becomes longer, it means that the belt has been deformed and needs to be replaced in time.

Loose belt cracking: If the belt is found to have reduced hardness, abrasion, fiber breakage, cracks, burrs, etc., it indicates that the belt has been damaged and cannot be used.

Summary: Counterfeit and inferior belts will not only affect the normal operation of the engine and accelerate the damage of the vehicle, but may also affect the driving safety of the driver. Therefore, for our own safety, we must carefully discern when purchasing belts, compare them carefully, and must purchase them from regular automotive belt manufacturers. At the same time, in the daily use process, it should be timely maintained and discovered in time.

For car owners who are familiar with machinery, the most difficult part of replacing the automotive v belt is to adjust the belt tension. The tension should not be too loose or too tight. Whether the belt tension is suitable or not depends on not slipping when dragging a certain torque. Improper maintenance, improper installation due to lack of tools, and worn pulley grooves or worn side belts are all causes of improper tension. Therefore, the following steps should be taken when selecting automobile triangle belts:

(1) Make sure that the car and the fan cannot be started when the belt is replaced.

(2) Loosen the installation lock column and adjusting bolt, and move the generator to remove the old V-belt.

(3) Put the new V-belt on the pulley. Never use a screwdriver or a spudger to pry the belt onto the pulley. Doing so will lose tension and shorten the life of the belt.

(4) After inserting the V-belt into the wheel groove, move the parts of the generator and the generator body that are not easy to pry, and then tighten the adjustment bolt.

(5) Consult the maintenance manual, car manual, and V-belt product instructions, and select the appropriate tension.

(6) Use the tension gauge to accurately measure the tension of the belt. The finger pressure method is not as accurate as the tensiometer. In modern engines, the tension of the belt is relatively high, that is, the belt pulley bears a greater tension, the distance between the belts is shorter, and the belt cross section is less. Therefore, the tension estimated by the feeling is different from the actual tension. Shiatsu is a subjective method of measurement, which varies from person to person. When measuring by finger pressure method, different models have different requirements.

(7) After running the belt for 15 to 20 minutes, make the belt fit the pulley groove, and the tension will be relaxed. Therefore, the belt must be adjusted again.

As an important part of the operation of the car, the belt is connected to various parts. Once it breaks or slips, the related air-conditioning compressor, power steering oil pump, alternator, etc. will be adversely affected. Therefore, it is very important to master the identification method of the automobile belt, and it is also important to know the replacement cycle of the belt. The following are some methods for identifying the quality of automobile belts and determining whether the belt is damaged.

How to identify the advantages and disadvantages of automobile belts?

1. Smell

True: No odor

False: There is a pungent smell of smelly gum.

Smelling is the first step in the identification of the advantages and disadvantages of automotive belts, and it is also a relatively effective trick. Often inferior rubber products will have a pungent smell of gum. The car owner can distinguish it with just a little attention.

2. Take a look

For the same reasons as above, counterfeit products usually make a fuss about materials and processes in order to save costs. The products produced are generally rough, and the printed fonts are relatively vague.

3. More comparison

A repair shop or store that sells counterfeit and inferior belt products will usually have the same specifications but several prices. It is recommended to make a careful comparison of these products with different prices before choosing.

Suggestion: The best way to deal with counterfeit and shoddy products is to choose regular purchase channels. The genuine parts of most automotive belt manufacturers are only sold through regular companies to distinguish counterfeit and shoddy goods from the gray market. Genuine products are not sold through unauthorized distribution channels. Therefore, it is best to choose the corresponding regular store when replacing the car belt.

With the rapid development of society, more and more families or individuals have purchased cars. But as the saying goes, you can’t afford a car from buying a car, and you can’t repair a car from affording a car. Why? Because everyone is poor in car maintenance knowledge of various parts of the car.

Knowledge and recommendation for the purchase of belt:

Most friends will think that in theory, the car should be able to drive 100,000 kilometers or more, or drive for three to five years. This is actually wrong. The belts are all rubber parts. Everyone knows that rubber will age.

The general use period of automotive timing belt is 2 years. The high temperature when the engine is running, the cooling when the car is stopped, the greasy impurities, the matching of the timing belt tensioner and the incorrect method during installation will lead to a shortened service life of the timing belt, so it caused another problem of kilometers. New car timing belts generally run 80,000-100,000 kilometers. After the timing belt is replaced, the service life of the belt will also be reduced due to the depreciation, use, and equipment of the car. Therefore, it is best to replace the timing belt in time.

Everyone needs to always pay attention to some things to replace the purchased belt:

When changing the belt, please pay attention to the correct operation of the operator in severe cold or scorching heat. Do not twist the timing belt hard. This will cause the internal fibers of the belt of the timing belt to break severely, which seriously affects the service life. When installing an automobile belt, the tensioner must be adjusted and cannot be pryed up directly with a wrench or hard object. If you see cracks on the outer surface of the timing belt and the rubber smell is very strong during use, you need to pay attention to whether the belt is aging. There are abnormal noises while driving, you need to pay attention to whether the car belt is installed correctly, or the quality and tooth shape of the belt are qualified, and match the generator timing pulley. Therefore, it is time to consider replacing the belt.

In the past, the application of electronic modules to automobiles was relatively simple. Today, a new form of technology is emerging. Vehicle systems are connected to sophisticated electronic devices that drive modularity. With the increase in cabin systems, human-machine interfaces, radars, and cameras, the number of multi-interface printed circuit boards (PCBs) and flexible components is also increasing. These components require connector products to enhance signal integrity and ensure transmission speeds in harsh environments.

The latest trend in the market is the integration of connected sensors, and the need for interconnection has created huge business opportunities for suppliers.

Trend 1: Human Machine Interface (HMI) connection

More and more applications use interfaces for communication, and most user interfaces have flexible board-to-board (F-to-B) connection points that require flexible printed circuit boards or board-to-board connectors.

The demand for sensors, microphones, speakers, and cameras is driving increased modularity, which requires more and better flexible printed circuits (FPCs), flexible flat cables (FFCs), board-to-board, and wire-to-board signal connections.

Trend 2: Durability requirements for harsh environments

Flexible components and printed circuit boards are becoming more complex. Harsh environments require higher signal integrity and more stable retention characteristics to withstand shocks and vibrations, which requires more and better flexible printed circuits (FPC), flexible flat cables (FFC), board-to-board and wires Signal connection to the board.

Consider the need for high-performance, durable interconnects early in the development process.

Trend 3: Limited space requires design flexibility

Automotive applications are getting smaller and smaller. The increased modularity limits the space between the connector and other components, requiring more space-matched miniature connector products.

Miniature connectors with multiple contact surfaces and orientations address the design challenges presented by designers with space, location, and connector entry points.

Vehicle electronics now require higher speeds and signal integrity to transmit higher bit-rate data streams.

The key to success in this area is a high-speed solution that supports the signal integrity (SI) required for sensor, camera, human-machine interface, and system communication.

Sunkye is a professional mil spec military connector manufacturer and supplier, if you are looking for automotive power connectors, contact us now.

D-sub connectors are bulky and durable, which made them suitable for being applied in harsh environments where durability is extremely important. They can also be compatible with many old-fashioned devices. For these advantages, D-sub is widely used in factories, manufacturing workshops and industrial environments.

From the purpose of using automotive connectors,in order to ensure better driving of the car, Sunkye can divide the reliability of the connector into the tightness of the connector in use, the performance of fire protection, the performance of shielding, and the performance of temperature control.

Generally speaking, when discussing the tightness of automotive connectors, it does not only refer to the tightness to water. In this area, the current popular international management specification is IP67, and this specification is now the highest level in the automotive industry. Although the requirements for waterproofing are different in different parts of the car, many car manufacturers will choose IP67 to ensure the tightness of the connector of their car.

In the driving of a car, the power source is a very important energy source, which is not only related to the normal work of the engine, but also often involves the use of the power source when people are driving. So in the car's power supply system, car connectors have different divisions. Certain sealing measures can be implemented between the male connector and the device, between the male connector and the cable, between the male and female connector, and between the female connector and the cable.

In the realization of the sealing performance of automotive connectors, the seal ring is a commonly used tool. This tool can not only achieve the effect of fixing between different hole positions, but also the effect of sealing. It can not only ensure the stable operation of automobile equipment, but also ensure the waterproof performance of automobile equipment in work.

In the production of seal rings, silicon rubber is mostly used. This material is made by liquid silicon and solid silicon after certain chemical changes.

Now that electronic circuit technology is an important aspect of the automotive industry. In order to ensure the stable operation of electronic circuit technology, people have applied many shielding technologies in the production of automobiles. These shielding technologies not only play a protective role in the electronic circuit of the car, but also play a role in anti-interference and anti-radiation in the parts of the car. In addition, they can also protect the stable operation of the automotive connector.

Shielding technology can be divided into two types: internal shielding and external shielding. When using an external shield to protect a car connector, two identical shield shells are usually assembled to form a shield layer, and the length of the shield layer can cover the entire connector length. It is also necessary to ensure that the shield shell There are enough lock plate structures to ensure the reliable installation of the shielding layer. In addition, the shielding material used must not only be treated by electroplating, but also be treated to prevent chemical corrosion.
