The car generator generates electricity by connecting the motor to the generator belt, then connecting the generator to the belt and using the motor to drive the generator to produce electricity. Therefore, if the car's alternator belt is aged or loose, it will have some impact on the car. So let's take a look at the symptoms and effects of your car's alternator belt aging and loosening. The symptoms and effects caused by the aging of the automobile alternator belt are as follows: 1. The battery fault light triggers an alarm. When the generator belt is loose, the seal with the pulley is reduced and the efficiency of the transmission is reduced, limiting the power output of the generator. When power generation is insufficient for a long time, an alarm display will be sent to the monitoring systemTurn on the vehicle's power supply and the battery power warning light will illuminate on the dashboard. 2. There is an abnormal, high-pitched noise coming from the engine compartment. When the generator belt is relaxed, the friction between the belt and pulley decreases and the relative slip increases significantly. When the belt slides on the pulley, it will make a high-pitched abnormal sound, which is very annoying. In addition, this sliding friction will further promote the aging of the belt, and the belt will crack. If it is not replaced in time, the belt will break. 3. The engine stops and starts or is difficult to start. When the generator belt is loose, the operating efficiency of the generator is reduced, the battery is not fully charged, and it becomes difficult to start the vehicle. In addition, due to the low output voltage of the generator, the power supply is insufficient.irritating while driving, which can easily lead to a flameout. 4. The light flickers then dims. When the belt is loose, the generator output voltage will decrease and can also cause lighting problems in the vehicle. When power generation is insufficient, problems such as flickering and dimming may occur when the lights are turned on, affecting driving safety. 5. Other belt drive components are operating abnormally. Components such as vehicle steering pumps and air conditioning compressors often share a belt drive with the generator. Once the belt becomes loose, the functions of many components requiring power from the belt will also be limited. Therefore, problems such as heavy vehicle steering and poor air conditioning cooling effect may also be caused par loose belts. How often should a car's alternator belt be replaced? Generally speaking, the car generator belt needs to be replaced every 100,000 to 120,000 kilometers, and the service life is also in this range. When inspecting the belt, if it is found that the core is broken and the groove section is broken, it should be replaced in time. The belt also needs to be replaced when the belt cover separates from the cord or the drawstring comes loose. Additionally, when the belt is placed on the pulley, there should be a gap between the inner diameter of the belt and the bottom of the pulley groove. If there is no gap, the belt should also be replaced.
The following problems can occur with the engine drive belt: There may be no load. When not under load, our belt transmitssion will be too loose and will slip. At that time we should check it. time Find out why the generator is not producing electricity, if the regulator is malfunctioning, or if there may be a circuit fault. Sometimes problems such as too low charging current may arise, caused by insufficient voltage of the generator itself, poor technical condition of the regulator or excessive resistance in the charging circuit. If the charging current is too large, there is also a problem. The car's ammeter pointer gradually deviates to the maximum charging current position, but when we drive at night. During driving, the engine speed will be very high, and the gauges and instrument lights will become very bright.
If the engine drive belt is installed too loosely or too tight during the installation process, the belt will wear prematurely. If she's instalted too loosely, this will also result in a relatively large loss of the corresponding energy production. So it's normal, but after installing it, we turn the belt over by hand, and it can form about 90 degrees, so it's basically normal.
When our engine drive belt makes an abnormal noise, it is probably because the drive belt is loose. We'd better go to the competent repair shop to check the tightness. When our drive belt slips. A certain sound will be produced, then friction and high temperature will occur, which will cause our transmission belt to stretch. After stretching, it will be more likely to slip.
The car engine drive belt also needs to be replaced regularly. Normally we should replace it once after driving about 80,000 kilometersor have used it for two years. Since the engine transmission belt is made of rubber, when it is used for a long time or the mileage is high, corresponding aging will occur. If the aging is severe, it will break and the engine will not produce energy. 'electricity.
