Abstract

The invention discloses an overrunning alternator pulley used for transmitting torque between a shell and a transmission shaft uniaxially. The overrunning alternator pulley is characterized by comprising a mandrel, a ferrule, a roller pin, an outer ring and rolling bearings, wherein the mandrel is arranged on the outer surface of the transmission shaft in a sleeving manner; the ferrule is arrangedon the outer surface of the mandrel in a sleeving manner; the roller pin rotates relative to the surface of the ferrule; the outer ring is arranged on the outer side of the roller pin; the rolling bearings are arranged at the two ends of the ferrule and the outer ring correspondingly; and the ferrule is made of a first material, the mandrel is made of a second material, and the hardness of the first material is greater than that of the second material.

Description

Technical field [0001] The invention relates to a component of a vehicle, in particular to an overrunning pulley. Background technique [0002] Generator Overrunning Alternator Pulley is a device that transmits torque in one direction based on the principle of one-way clutch. Unlike the traditional rigid pulley, the overrunning pulley only allows the pulley to rotate in one direction, which reduces the vibration of the engine accessory drive system, which can significantly extend the service life of each accessory system component. [0003] Such as figure 1 As shown, when the crankshaft rotation speed fluctuates upwards, that is, the outer ring 1 of the pulley accelerates, and the outer ring 1 of the generator pulley 1 drives the one-way clutch needle 3 to roll clockwise. Due to the inclined surface design of the mandrel 2 of the overrunning pulley, when the clutch needle 3 rolls in the clockwise direction, the movement space of the clutch needle 3 becomes narrower. The clutch nee...
