How much do you know about car belts

Function of car belt

Automobile belts are also called automobile transmission belts. Its main function is power transmission. The transmission belt on the car is responsible for driving the

movement of all parts. If it breaks, the car won't move.

Classification of car belts

There are three common belts in automobiles: V-belt, V-ribbed belt and timing belt.

The installation position of the car belt

In automotive applications, they are mainly installed in automotive engine crankshaft cams, water pumps, generators, air-conditioning compressors, power steering

pumps and other locations.

Structure of car belt

V-belt consists of three parts: upper cloth, tension thread and lower glue.

V-ribbed belt is similar to V-belt and consists of three parts: top fabric, tension thread and bottom rubber;

The main difference between the two is: multiple micro V-ribbed belt surface composition, wide and thin, making it have a greater degree of flexibility, surrounded

by smaller driving wheels so that the multi-ribbed belt (MICRO-V) can be Transmission power "snake-shaped" drive device. Such a transmission device can drive the

plurality of transmission power engine accessories.

Timing belt structure: gluing and fiber, tension line, gluing. The tension thread is made of very strong glass fiber. The bottom layer of the timing belt is composed of

precision casting mold teeth.

Belt preservation method

Although the timing belts are strong, they are very fragile and fragile. If the timing belt is bent too much in either direction, the glass fiber will easily break. Therefore,

the timing belt should not be stored arbitrarily, but should be packaged and sealed in the box until it is installed.

How to check the belt

First check that the transmission belt selects the longest unsupported span. The moderate pressure is applied to the belt tension of the middle with the thumb. If the

belt reduction is about 10 mm, the belt tension should be just right. If the belt tension is too large or too loose, it may cause the sliding gear transmission to be incomplete.

Adjust the belt tightness so that the belt will be easily stretched and deformed, but it will accelerate the wear of the pulley and the bearing. For this purpose, the relevant

adjustment should loosen the nut or bolt, and the belt tension will be adjusted to the best condition.

How to make many parts of a car move together in an orderly manner? What we rely on is the function of the transmission belt! If there is a problem with the safety, our

car will not be able to move forward. Because the engine drives various auxiliary mechanisms such as air-conditioning compressors, power steering pumps, and alternators

through belt drives, if the belt slips or is disconnected, the relevant auxiliary mechanisms will not work properly, affecting the normal use of the car. Therefore, it is necessary

to check the transmission belt regularly.
