Auto generator tightening wheel action
The main function of the auto generator tightening wheel is to adjust the tightness of the belt, reduce the vibration of the belt and prevent the belt from slipping, so as to ensure the normal and stable operation of the transmission system . Specifically, the tension pulley automatically adjusts the tension of the belt to ensure that the belt works in the best condition of tension, avoids wear caused by improper tension, prolongs the service life of the belt, and improves the efficiency and reliability of the transmission system .
The structure of the tension wheel includes a fixed shell, a tensioning arm, a wheel body, a torsion spring, a rolling bearing, a spring sleeve and other components. It can automatically adjust the tension according to the tightness of the belt to ensure the stability, safety and reliability of the transmission system. With the extension of the belt use time, the tension pulley may be extended, so it needs regular inspection and maintenance .
Common faults include abnormal sound, reduced spring strength, belt failure to operate, oil leakage, fracture deformation and so on. In order to avoid these failures, it is recommended to replace the tightening wheel every 3-5 years or about 80,000 to 100,000 kilometers, the specific time can refer to the vehicle maintenance manual .
In addition, regular inspection and maintenance is also the key to keep the expansion wheel working properly .
is an important part of the automobile transmission system, mainly used to adjust the tightness of the generator belt to ensure the stable operation of the transmission system. Its main functions include:
Adjusting belt tension : the tightening wheel automatically adjusts the tension of the belt to ensure that the belt maintains a proper tension during operation, preventing the belt from loosening or being too tight, thereby reducing vibration and noise, and avoiding the belt slipping .
reduce vibration and noise : by adjusting the belt tension, the tightening wheel can effectively reduce the vibration and noise of the belt during operation, and improve the stability and reliability of the transmission system .
extend belt life : By maintaining proper belt tension, the tension pulley can reduce the wear caused by improper tension, thus extending the service life of the belt .
ensure the normal operation of the engine : the normal operation of the tension pulley is very important to the normal operation of the engine, it ensures that the engine components can obtain stable power transmission, to avoid the failure caused by loose or too tight belt .
Structure and working principle
The tightening wheel consists of several parts, including hub, bearing, tensioning arm, etc. The hub is used to hold the belt and drive its operation, the bearings ensure smooth rotation of the hub, reduce friction and resistance, and the tension arm is responsible for adjusting the tightness of the belt. During the working process, the tightening wheel automatically adjusts according to the tension of the belt to keep the belt in the appropriate tension range to ensure smooth power transmission .
Common faults and maintenance suggestions
abnormal sound : if the expansion wheel bearing is damaged or insufficient lubrication, it may emit abnormal sound, affecting the normal use of the car .
spring force decrease : the spring force decrease will cause the expansion wheel can not maintain the appropriate tension, may need to be replaced .
belt failure to operate : In extreme cases, the tightening wheel may become stuck, causing the belt to fail to operate .
oil leakage : hydraulic tension pulley may have oil leakage problem, affecting its normal work .
fracture deformation : improper installation or improper use may lead to fracture deformation of the tension wheel .
In order to ensure the normal work of the tightening wheel, it is recommended to replace the tightening wheel every 3-5 years or about 8-100,000 kilometers, and the specific time can be referred to the vehicle maintenance manual. When purchasing and replacing, the tightening wheel should be selected with guaranteed quality and matching the model.
