What is the reason for the squeaking of car belts
Release time:

1. Belt aging Because the main component of the transmission belt is rubber, especially in winter, the rubber will become hard and brittle, and the friction coefficient will decrease. If the belt is excessively worn, it will also make a "squeaking" sound. The belt is made of rubber, and after aging, the friction force will decrease, which cannot transmit power well and may cause slipping. After slipping for a while, the banana will soften and the sound will disappear. The motor belt not only drives the generator, but also needs to drive the compressor, booster pump, water pump, and other accessories. Continuously running, ensuring sufficient power, air conditioning, and assistance for the car. Over time, the belt will age and slip, and then make a squeaking sound.

2. When the belt tension is insufficient, the belt is also prone to slipping like aging. Many friends who understand cars should know that the belts used in most cars on the market nowadays are automatically adjusted for tightness. They are designed with a large spring to press the belt and adjust the tightness of the belt. When the belt is too loose, the friction force will also decrease, causing abnormal noise due to slipping.
3. Severe belt wear
When the belt of a car is severely worn, there will be a significant reduction in the contact area between the belt and pulley. At this point, as long as the belt is pressed hard, it will deeply sink into the groove of the pulley. When the belt rotates, the opportunity becomes very difficult, and the friction force also increases significantly, just like when we ride a bicycle and the chain cannot rotate, it makes a very harsh sound. At this point, we need to replace the belt with a new one as soon as possible.
