There are three types of belts commonly found in automobiles: fan belts, V-ribbed belts, and timing belts. Installation position of automobile belt: In automobile application, it is mainly installed in the position of automobile engine crankshaft wheel to cam, water pump, generator, air conditioner compressor, power steering pump, etc.
1. The
Fan Belt is a belt driven by the crankshaft. Its main purpose is to drive the engine fan and water pump.
2. The multi-ribbed belt, also known as the air-conditioning belt, is used to drive the generator, the air-conditioning compressor, and the power steering pump, hang on the crankshaft pulley, and be tightened by the air-conditioning belt tensioner. When the belt is damaged, the power assist will feel heavy and there will be no steering assist; if the air conditioner is turned on, the air conditioner compressor will not start, so it cannot be cooled.
3. The
Timing Belt is an important part of the engine distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust time.
The function of the timing belt is when the engine is running, the stroke of the piston (up and down movement) the opening and closing (time) of the valve and the sequence (time) of ignition. Under the connection of "timing", it is necessary to maintain "synchronization" at all times run.
The engine drives various auxiliary mechanisms through the 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, thus affecting the car. normal use. Therefore, it is necessary to check the drive belt regularly.
