Abstract

The invention provides a connecting structure for a vehicular generator for eliminating coupling of mechanical vibration noise, which solves the problem of resonance and noise easily generated by the prior vehicular generator and the engine. The structure is provided with a hitching pin of a mounting frame of the generator, wherein a compensating sleeve is arranged in a hole of the hitching pin; and a through bolt is arranged in the compensating sleeve. The connecting structure is characterized in that the compensating sleeve is made of PC engineering plastics; and an elastic element is arranged between the compensating sleeve and the through bolt to eliminate vibration when the engine works and avoid resonance of the generator and the engine. The connecting structure has the advantages that rigid connection between the generator and the engine is changed into elastic connection so as to effectively absorb the vibration generated by the engine, avoid the resonance generated by the generator and the engine, and eliminate noise generated by vibration coupling; and the compensating sleeve is made of the PC engineering plastics to meet the use requirement of the vehicular generator under various complicated environmental conditions, thereby reducing friction resistance, and prolonging the service life of the elastic element.

Description

technical field [0001] The invention relates to a vehicle generator connection structure capable of eliminating mechanical vibration and noise coupling. Background technique [0002] The alternator used in vehicles is usually installed on the engine, that is, the mounting bracket hanging legs of the alternator are fixed on the casing of the engine through through bolts, forming a vibrating body with the engine. During installation, in order to ensure the tightness of the hanging feet of the engine and generator mounting brackets, and to make the cooperation between the hanging feet of the generator A metal compensation sleeve is installed inside, and the gap fit between the compensation sleeve and the hanging feet of the generator installation bracket, the axial length of the compensation sleeve is greater than the axial length of the hanging foot hole of the generator installation bracket. During installation, through the axial tightening of the through bolts, the compensa...
