The tensioning wheel is mainly composed of a fixed shell, tensioning arm, wheel body, torsion spring, rolling bearing and spring sleeve, etc. It can automatically adjust the tensioning force according to the different tightness of the belt, so that the transmission system is stable, safe and reliable.
The tightening wheel is a wearing part of the automobile and other parts, the belt with a long time is easy to wear, the belt groove grinding deep and narrow will appear to be elongated, the tightening wheel can be automatically adjusted through the hydraulic unit or damping spring according to the wear degree of the belt, in addition, the tightening wheel belt running more stable, less noise, and can prevent slipping.
The tensioning wheel belongs to the routine maintenance project, which generally needs to be replaced for 60,000-80,000 kilometers. Usually, if there is abnormal noise at the front end of the engine or the location marked by the tensioning wheel tensioning force deviates too much from the center, it means that the tensioning force is insufficient. It is recommended to replace the belt, tensioning wheel, idler wheel and generator single wheel when the front end accessory system sounds abnormally at 60,000-80,000 km
