Зачем нужен шкив муфты свободного хода генератора и как он работает?
In the past, 60 or 70 amp alternators were used commonly, with solid pulleys. Today’s new cars with high-resolution touch screens, electronics, entertainment centers, USB ports, and an increasing number of ADAS features may require 120 amp, 160 amp, or higher amp alternators to power their electrical and electronic systems. Since the beginning of the 21st century, we have been developing and manufacturing automotive Overrunning alternator pulley with built-in one-way freewheel clutch. Currently, the type of alternator freewheel clutch pulley can absorb speed variations with high reliability.
OAP Цель работы:
OAP: Overrunning Alternator Pulley, or “Freewheel” Clutch pulley, when the speed of the drive belt is suddenly reduced. The overrunning alternator pulley accomplishes this by allowing the alternator freewheel clutch pulley to “freewheel” or rotate independently of the engine. This means that the alternator rotor can be coasted to a stop when the engine is turned off. This “override” function eliminates the squealing and slipping that occurs when the engine slows down, the transmission shifts, or shuts down. This technology of reducing noise, vibration and harshness (NVH) minimizes system stress and extends belt and tensioner life.
What Beyond bring from Alternator freewheel clutch pulleys:
Шкив позволяет генератору "свободно вращаться" или "перебегать". Это предотвращает проскальзывание ремня и снижает вибрацию. Кроме того, система требует меньшего натяжения, и вы даже можете использовать более узкий ремень. Это может улучшить экономию топлива на 1,5% - 2%.
However, due to the way the alternator freewheel clutch pulleys operate, they have a limited lifespan. In the next article, we’ll learn how to recognize beyond freewheel clutch alternator pulley wear signs.
