An automatic adjusting device for the pulley of an automobile generator

Abstract

The utility model discloses an automatic adjusting device of automobile generator pulley, include: engine machine case, tension adjusting mechanism is installed in the inside of engine machine case for realizing adaptation pulley automatic regulation, wherein, tension adjusting mechanism includes first support and the second support of fixed top through fixed column fixed in first support. The utility model second spring will promote second branch arm rotate around second rotating seat, drive its second tightener and move outward, and elastic telescopic link provides auxiliary support and stroke, therefore, when the tightness of transmission belt changes, first spring and second spring will act on first branch arm and second branch arm respectively, through the telescopic of elastic telescopic link, make first tightener and second tightener can automatic regulation position, and then change the prestress of transmission belt, always keep the belt in the best tension state, thereby solved the problem that manual regulation can not adapt to change in real time.
