How many belts does this car have? What are the functions?

There are three kinds of belts commonly used in automobiles: fan belt, multi-wedge belt and timing belt. Installation position of automobile belt: in automobile application, it is mainly installed in the rotating cam of crankshaft such as automobile engine, water pump, generator, air conditioning compressor and power steering pump.

1. The fan belt is driven by the crankshaft. Its main purpose is to drive engines, fans and water pumps.

2. V-ribbed belt, also known as air conditioning belt, is used to drive generators, air conditioning compressors and power steering pumps. These belts are hung on the crankshaft pulley and fixed by the air conditioning belt tensioner. Belt damage, power drop, no power steering; If the air conditioner is turned on, the compressor of the air conditioner will not start and cannot be cooled.

3. Timing belt is an important part of engine valve system. Through the connection with crankshaft and a certain transmission ratio, the accuracy of intake and exhaust time is ensured.

When the engine is running, the timing belt is used to start the piston stroke (up and down) and the valve opening and closing sequence (time). For timed connections, you should always run synchronously.

The engine drives various auxiliary machines such as air conditioning compressor, power steering pump and alternator through belt drive. If the belt slips or breaks, the corresponding auxiliary mechanism will not work normally, thus affecting the normal use of the car. So it is necessary to check the belt regularly.

Extended data:

Regular maintenance of automobile seat belts;

Automobile maintenance has a definition of wear and aging prevention of automobile engine belt. Before the definition, rare root zone is the first achievement of each zone. The rubber of the belt also has the problem of aging. If the rubber of the adhesive tape is seriously aged, it must be replaced with a new adhesive tape in time.

The car engine is the brain of the car. If the engine breaks down, the whole car is useless. Cars running on the road for a long time every day may lead to wear or aging of the engine belt, so car owners usually start to check the belt after a while to avoid unnecessary trouble.

Automobile maintenance has a definition of wear and aging prevention of automobile engine belt. Before the definition, rare root zone is the first achievement of each zone. Air conditioner retractor, power steering pump, alternator and other auxiliary machines are all belt-driven.

If the belt is broken, it may slip, which will make the relevant auxiliary machines lose their functions or reduce their functions, thus affecting the normal operation of the car.
