Auto air conditioning pump belt action.
Automobile air conditioning pump belt function is to drive the engine fan and water pump. The multi-wedge belt, also known as the air conditioning belt, is used to drive the generator, air conditioning compressor, steering booster pump, hanging on the crankshaft pulley, tightened by the air conditioning belt tightening wheel.
There are three kinds of belts commonly used in cars, fan belts, multi-wedge belts and synchronous belts. Automotive belt installation position: In automotive applications, it is mainly installed in CAM, water pump, generator, air conditioning compressor, steering booster pump and so on. The fan belt is a belt driven by the crankshaft and its main purpose is to drive the engine fan and water pump. The multi-wedge belt, also known as the air conditioning belt, is used to drive the generator, air conditioning compressor, steering booster pump, hanging on the crankshaft pulley, tightened by the air conditioning belt tightening wheel. When this belt is damaged, it will feel the power is very heavy and there is no steering force; If the air conditioner is on, the air conditioner compressor will not start, so it will not cool.
The timing belt is an important part of the engine distribution system, which 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 synchronous belt is the stroke of the piston when the engine is running, the opening and closing of the valve, and the sequence of ignition. Under a timed connection, it is necessary to keep synchronized operation at all times. The engine drives various auxiliary mechanisms through belt transmission, such as air conditioning compressors, power steering pumps, alternators, etc. If the belt slips or breaks, the relevant auxiliary mechanism will not work normally, thus affecting the normal use of the car. Therefore, it is necessary to check the transmission belt regularly. The generator belt is the most important belt on the car, which connects the generator, air conditioning compressor, booster pump, idler, tension wheel and crankshaft pulley. Its power source is the crankshaft pulley, the power is provided by the rotation of the crankshaft, and then the other parts are driven to run together. When there is a small crack in the contact surface between the belt and the pulley, it needs to be replaced. If it is not replaced, it will cause the generator to fail to generate electricity, and the booster pump can not move in the direction, which is a very dangerous situation.
Here are some suggestions for belt replacement cycles in your car:
1. In general, car belts are recommended to be replaced after 60 to 70 thousand kilometers or about 5 years of use. In order to ensure safety and avoid accidents or damage to the engine caused by breakage of the belt during use, it is recommended to replace it in advance when it is close to the recommended replacement time.
2. Another common replacement cycle is to replace it every 50,000 to 60,000 kilometers. However, the specific replacement time also needs to refer to the vehicle maintenance manual. If the belt is found to have multiple cracks, it should be replaced in time. These belts are mainly used for air conditioning compressors, although they do not directly affect the overall operation of the vehicle, but modern vehicles are increasingly dependent on air conditioning.
3. For the timing belt, it is usually recommended to replace it when traveling 160,000 kilometers. Similarly, the replacement cycle of the external air conditioning belt is also 160,000 kilometers.
4. The replacement cycle of the generator belt is usually every 2 years or when the driving distance is more than 60,000 kilometers. This is also a routine maintenance recommendation to ensure the proper operation of the belt.
5. It should be noted that the replacement cycle of the car belt is not a fixed value. The owner should decide whether to replace it in advance according to his driving habits and driving environment. In harsh driving conditions, it may need to be replaced after less than 60,000 kilometers.
