Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the axial positioning accuracy of the entire wheel train is affected due to the lack of reliable axial positioning between the one-way clutch and the support bearing and the mandrel in the existing pulley assembly for the automotive alternator , resulting in inconsistencies in the effective length of the transmitted torque; slipping failures will occur between the one-way clutch and the mandrel; when the road conditions are relatively bad, dust will enter the support bearing during driving and affect the service life, etc.

Embodiment Construction

[0013] Such as figure 1 , 2 The automobile alternator integral pulley assembly shown in the present invention has a cylindrical structure as a whole, and has a mandrel 1 set on the end of the rotating shaft of the alternator, and the inner circle surface in the middle of the mandrel 1 has internal threads 1. It is threadedly connected with the rotating shaft of the alternator. There is an internal spline on the inner surface of the front end of the mandrel 1, which is matched with a tool with an external spline on the head, and is used for assembling the mandrel 1 and the rotating shaft of the alternator. A driven pulley 2 is arranged concentrically with the mandrel 1 outside the circumference of the mandrel 1, and a one-way clutch, a front support bearing and a rear support bearing, a front support bearing and a rear support are arranged between the mandrel 1 and the driven pulley 2. The bearings are respectively arranged at the front end and the rear end of the one-way clut...

Abstract

This invention relates to one airmobile alternating motor integral slides bus with imbed single clutch, which is fixed on end of rotation axis and to drive automobile alternating moor through hook wireless joint band between the drive band wheels of the axis end. This invention is one integration structure outer ring composed of clutch outer ring, front supportive ring and back supportive ring.

Description

technical field [0001] The invention relates to an integral pulley assembly for an automobile alternator with a built-in one-way clutch. The belt, which drives the car's alternator above. Background technique [0002] In order to meet the high power requirements of automotive alternators, the pulley assembly, as the most feasible solution to realize this function, has attracted more and more attention from many OEMs. At present, domestic automobile generators use simple pulleys without one-way clutches. Under the requirements of increased electric power of automobiles, slippage is easy to occur, causing the whole vehicle to fail to work normally. The main reason is that the entire wheel around the automobile engine is considered The service life of the system, including the belt and the idler pulley, the engine drives the generator through the wheel system. When the engine stops working, since the entire wheel system is a driven part, including the pulley of the generator, ...
