Automobile maintenance has definitions for the wear and aging prevention of automobile engine belts. There are rare belts at the front end of the definition machine, and each belt bears the primary result. Assuming that the belt is broken, or there may be slippage, it will cause the related auxiliary equipment to lose or reduce its function, and then affect the normal use of the car.
1. The 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.
2.The classification of car belts
There are three types of belts commonly used in automobiles: V-belt (automobile V-belt or also known as trimming belt), V-ribbed belt (PK belt) and timing belt. For details, you can reply 1 to view.
3.The installation position of the 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.
4. The structure of the car belt
The V-belt is composed of three parts: the top fabric, the tension line and the bottom rubber; the V-ribbed belt is similar to the V-belt, but also consists of three parts: the top fabric, the tension line and the bottom rubber; the main difference between the two: The micro-V surface is wider and thinner, so that it has greater flexibility when it wraps around the smaller transmission wheel; it enables the multi-ribbed belt (MICRO-V) to transmit power in the "snake-shaped" transmission device. 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.
The reflection method of the belt is very simple. First, check the tension of the belt. At this time, you can use your thumb to forcefully press the belt between the two pulleys. The pressing force is about 10kg. Assuming the belt depression is about 10mm, the belt tension is considered suitable. If the reduction is too large, it is considered that the belt tension is lacking. Assuming that there is almost no reduction in the belt, it is considered that the tension of the belt is excessive.
In addition, car maintenance must also pay attention to belt wear. The old belt wears severely, which sharply reduces the contact area between the belt and the pulley. At this time, you only need to press the belt hard and the belt will sink deeply into the groove of the pulley. The belt rubber also has an aging problem. Assuming that the belt rubber is seriously aging, it is necessary to change the belt in time.
A car engine is the brain of a car. If the engine is broken, it means that a car is useless. Cars have to run on the road every day. For a long time, it may cause wear or aging of the engine belt. Therefore, the owner usually starts to check the belt after a period of time to avoid unnecessary trouble.
