What are the benefits of generator one-way wheels?

Alleviate the impact of the generator and the adjustment of the power generation during the acceleration and deceleration of the vehicle, reduce the load caused to the engine at the moment of acceleration or deceleration of the engine and gear change of the gearbox, so as to reduce the load of the generator belt and increase the service life of the belt! Reduce engine vibration and noise!

Unidirectional alternator pulley is also called alternator overrunning pulley, which is called overrunning alternator pulley in English

Commonly known as the generator belt clutch, in fact, it refers to the belt pulley of one-way alternator.

The one-way belt pulley of the generator is composed of an outer ring matching the cross-sectional shape of the multi-wedge belt, a clutch unit composed of a stamped inner ring, an outer ring and a double needle roller bearing, a shaft sleeve and two sealing rings. In order to prevent the influence of water and other dirt, a protective cover is installed on its outer end face.

Its function is to decouple the alternator from the front engine accessory belt drive train, because the alternator has the highest rotational moment of inertia in the front engine accessory belt drive train. This means that the generator one-way pulley is a V-belt and can only drive the alternator in one direction.
