Why does Wuling Rongguang make a buzzing noise when running?
1 Answers
Wuling Rongguang making a buzzing noise when running is due to abnormal noise from the engine tensioner pulley bearing, which needs to be replaced promptly. Here is more information: 1. Composition of the generator tensioner pulley: The generator tensioner pulley is a belt tensioning device used in the automotive transmission system. It mainly consists of a fixed housing, tensioning arm, wheel body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the varying tightness of the belt, ensuring the transmission system remains stable, safe, and reliable. 2. Function of the tensioner pulley: The tensioner pulley is a wearable part in automotive components. Over time, belts tend to stretch, and some tensioner pulleys can automatically adjust the belt tension. Additionally, a tensioner pulley makes the belt run more smoothly, reduces noise, and helps prevent slipping.
