Causes of alternators producing unidirectional pulleys
The traditional power transmission is a belt drive: the belt between the engine and the generator is used to complete the power transmission. Minor speed changes on the engine side can cause instability and slippage of the belt, as well as accompanying noise, and even reduce belt life. Based on this, some manufacturers have been inspired by the use of several types of one-way clutches on starters. Since the beginning of the 21st century, they have developed and manufactured automobile generator pulleys with built-in one-way clutches. Sexual drive system.
