There are three types of belts common to cars: fan belt, multi wedge belt and timing belt.
Installation position of automobile belt: in automobile application, it is mainly installed in the position of automobile engine crankshaft to cam, water pump, generator, air conditioning compressor, power steering pump, etc.
1. Fan belt is a kind of belt driven by crankshaft, whose main purpose is to drive engine fan and water pump.
2. Multi wedge belt, also known as air-conditioning belt, is used to drive generator, air-conditioning compressor and power steering pump. It is hung on crankshaft pulley and tightened by air-conditioning belt tightening pulley. When the belt is damaged, it will feel that the power supply is heavy and there is no power supply for steering; If the air conditioner is turned on, the air conditioner compressor will not start, so it can not cool
3. Timing belt is an important part of engine valve system. It can ensure the accuracy of intake and exhaust time by connecting with crankshaft and matching with a certain transmission ratio. The function of timing belt is that when the engine is running, the stroke of piston (up and down movement) the opening and closing of valve (time) the sequence of ignition (time). Under the connection function of "timing", the "synchronous" operation should be maintained at all times.
The engine drives various auxiliary mechanisms through belt drive, such as air conditioner compressor, power steering pump, alternator, etc. if the belt slips or breaks, the relevant auxiliary mechanisms will not work normally, thus affecting the normal use of the car. Therefore, it is necessary to check the drive belt regularly.
