Function of car belt
Automobile belt is also called automobile transmission belt, and its main function is power transmission. The drive belt on the car is responsible for driving the movement of all parts. If it breaks, the car can't move.
Classification of car belts
There are three types of belts commonly used in automobiles: V-belts, V-ribbed belts and timing belts.
Installation position of car belt
In terms of automotive applications, it is mainly installed in the crankshaft cam, water pump, generator, air-conditioning compressor, and power steering pump of the automobile engine.
Structure of car belt
V-belt consists of three parts: top fabric, tension thread and bottom rubber;
The V-ribbed belt is similar to the V-belt and consists of three parts: the top fabric, the tension thread and the bottom rubber;
The main difference between the two: the V-ribbed belt is composed of multiple micro-V surfaces, which are wider and thinner, so that it has greater flexibility when it wraps around the smaller transmission wheel; this makes the multi-ribbed belt (MICRO-V) can Transmission of power in a "snake-shaped" transmission. This kind of transmission can drive multiple engine accessories to transmit power.
Timing belt structure: top rubber plus fiber, tension line, bottom rubber. The tension thread is made of a very strong glass fiber. The bottom layer of the timing belt is composed of the teeth of the precision mold.
Belt preservation method
Although the timing straps are very strong, they are very delicate and fragile. If the timing belt is excessively bent in either direction, the glass fiber is extremely easy to break. Therefore, the timing belt cannot be stored casually, but should be packaged and sealed in the box, and cannot be taken out until installation.
How to check the belt
First check the tension of the belt, and choose to apply moderate pressure with your thumb in the middle of the longest unsupported drive belt span. If the belt depression is about 10 mm, the belt tension is considered to be just right. If the tension of the transmission belt is too large, or too loose, it may cause slippage and incomplete transmission. If the transmission belt is adjusted too tightly, the transmission belt will be easily stretched and deformed. At the same time, it will also accelerate the wear of the pulley and bearing. For this reason, the relevant adjustment nuts or bolts should be loosened to adjust the belt tension to the best condition.
How to make the numerous parts of the car move together in an orderly manner? It depends on the role of the transmission belt! If there is a problem with the transmission belt, our car will not move forward. Because the engine drives various auxiliary mechanisms through a belt drive, such as the compressor of the air conditioner, the power steering oil pump, the alternator, etc., if the belt slips or breaks, the related auxiliary mechanisms will not operate normally, which will affect Normal use of the car. Therefore, it is necessary to check the transmission belt regularly.
