Automobile belts are also called automobile conveyor belts. The main function is to transmit power and drive the operation of all parts. If the belt is broken, the car will be paralyzed. There is no doubt that the belt is a very important part of the car. Today, I will take you up and take care of your belt so that you can travel without worries.
Classification of belts
Transmission belts are mainly divided into V-belts and V-ribbed belts. Both are composed of three parts: top fabric, tension thread and bottom rubber.
The difference is that the V-ribbed belt is composed of multiple miniature V-surfaces, which are wider and thinner. The special structure makes it have greater flexibility when surrounding a smaller transmission wheel, and can transmit power in a complex transmission device.
The timing belt is an important part of the engine's air distribution system. It is connected to the crankshaft and matched with a certain transmission ratio to ensure accurate intake and exhaust times.
The importance of belts
Transmission belts and timing belts are both very important. Always pay attention to inspections to ensure their healthy operation.
If the drive belt breaks, it will cause a series of problems such as generator strikes, power-assisted pump failure, and inability to move the direction, causing driving troubles.
If the timing belt breaks, the throttle and ignition system will not function properly. However, the piston will continue to operate due to inertia, causing the throttle rod to be bent by the piston, and even the engine cylinder head will be knocked out of the hole. In this case, the engine needs to be overhauled at least, and it is scrapped.
5 reasons that affect belt life
envirnmental factor
In order to improve the efficiency of the engine, some models will be equipped with turbocharging and other devices. However, the heat emitted will cause the temperature of the engine compartment with a high compression ratio to rise, which extremely tests the high temperature resistance of the belt.
Drive system factors
Transmission belts have high requirements on the transmission system. The coplanarity and coaxiality of the same transmission plane components directly affect the service life of the transmission belt.
In the entire transmission plane, only the transmission belt is a rubber component. After a long period of operation, the coplanarity or coaxiality of the original end face components will be damaged due to excessive wear.
Effect of flying foreign objects
The driving conditions of a car are very complicated. In a harsh driving environment, the belts and pulleys are very easy to splash foreign objects.
In the state of high-speed operation, the foreign matter is like a knife that continuously cuts the belt, causing damage to the transmission belt.
Belt bending
Cord is an important part of the belt, it will cause the attenuation of the belt tension under a small bending radius.
Especially the timing belt, its cord is made of relatively fragile glass fiber, it is very easy to bend, even under a very small bending radius, it can cause serious attenuation of the belt tension.
Installation tension
The installation tension will directly affect the use status of the transmission belt. If the tension is too small, it will cause the belt to slip; if the tension is too large, it will directly cause the belt to layer and lose its working ability.
Belt replacement standard
According to the standards of domestic vehicles, it is necessary to replace the transmission belt and timing belt in time after driving 60,000 to 100,000 kilometers.
At the same time, in order to ensure the service life of the vehicle, regular maintenance of the entire vehicle is also necessary.
