What does an alternator freewheel clutch do?
As opposed to traditional solid pulleys, they allow the alternator to “free-wheel” or “overrun” every time the engine decelerates and, at the same time, dampen vibrations at the alternator. They come in two types: one-way clutches (OWCs) and overrunning alternator decouplers (OADs).
How does an alternator clutch work?
The alternator pulley works the same way. This is where the clutched alternator pulley comes in – just like the bike, the alternator can “free-wheel” at the higher speed, spinning down gradually until the alternator speed matches the engine speed, at which point the pulley will engage again, just like your bike.
What is an alternator clutch?
An Overrunning Alternator Pulley (OAP) has a one-way clutch mechanism inside the hub that allows the belt to turn the alternator in one direction, but allows the alternator to free-wheel and spin at its own speed when the engine suddenly decelerates. Some replacement alternators come with pulleys and some do not.
Can you hand crank an alternator?
Can you hand crank a car alternator to power other supplies? – Quora. You can hand crank it. It has internal diodes to convert AC to DC. You need to turn it at least fast enough for it to generate enough voltage to overcome the forward voltage drop of the diodes.
How does an overrunning clutch work?
Overrunning clutches, sometimes called freewheel clutches, are used to freewheel in one direction while driving in another direction of rotation. When the driven shaft is rotating faster than the driveshaft, the clutch mechanically disconnects the driveshaft from the driven shaft. This engages the clutch.
How does an overrunning alternator pulley work?
“An Overrunning Alternator Pulley (OAP) has a one-way clutch mechanism inside the hub that allows the belt to turn the alternator in one direction, but allows the alternator to free-wheel and spin at its own speed when the engine suddenly decelerates.
Can a bad alternator pulley cause vibration?
Overrunning Clutch/decoupler pulleys have a much greater chance of making noise and vibration in the alternator, such as when they are about to fail. Solid pulleys do not fail, they are solid steel, no clutch in them, I’ve never seen any vibration in an alternator other than when the clutch/decoupler pulley fails.
How does the alternator free wheel?
It says in the conterman magazine article that clutch/decoupler pulley drives the alternator one direction and slips in the other direction. It says that this allows the alternator to “free wheel” when the motor slows down rapidly. Well I can tell you that alternators do not “free wheel” when they are charging.
