What are the common faults of Double joint universal coupling? How to solve them?
Publish Time: 2024-08-15
Double joint universal coupling (also often called double joint universal joint) is a key component in the automobile transmission system, and its stability and reliability are directly related to the driving safety of the vehicle.
1. Common faultsAbnormal noisePhenomenon: When driving or turning, a regular "clicking" or "humming" sound is emitted.Cause: It may be caused by bearing wear, aging or damage of oil seals, insufficient lubrication, etc.Poor maneuverability and difficult steeringPhenomenon: When driving or turning, the vehicle's maneuverability becomes poor and the steering is not flexible.Cause: This may be due to wear of internal parts of the universal joint, failure of the oil seal leading to poor lubrication, or improper installation of the universal joint.Steering wheel shaking or body shakingPhenomenon: During driving, the steering wheel shakes or the body shakes, and it intensifies with the increase of vehicle speed.Cause: This is usually related to the balance problem of the universal joint, sagging or bending of the shaft tube, loose connection bolts, etc.Fatigue cracksPhenomenon: Fatigue cracks will appear in the double universal joints after long-term use or overload.Cause: This is caused by factors such as material fatigue and stress concentration.Excessive temperaturePhenomenon: In a high temperature environment, the lubricating oil inside the double universal joint will fail, resulting in increased wear.Cause: This is mainly due to the high working environment temperature, which affects the performance of the lubricating oil.
2. SolutionRegular inspection and maintenanceRegularly check the status of the double universal joint, including the wear and aging of bearings, oil seals, lubricating oil and other components.Clean and replace worn or aged parts in time to ensure the good working condition of the universal joint.Correct installationWhen installing the double universal joint, follow the correct installation method to ensure the verticality and load uniformity of the coupling.Avoid increased wear and rust caused by improper installation.Choose high-quality productsWhen replacing the parts of the double universal joint, you should choose high-quality products with reliable quality.Ensure the service life and safety of the product.Strengthen lubricationMaintain the lubrication of the universal joint, and regularly add and replace lubricating oil.Ensure that the bearings and universal joint gears are fully lubricated to reduce wear and abnormal noise.Solve vibration problemsCheck whether the balancing parts or components of the universal coupling have dynamic balance compensation.Ensure that the two couplings are assembled on the same plane to avoid sagging or bending of the shaft tube.Tighten the flange connection bolts to prevent vibration caused by angle deviation.Treatment for specific faultsFor serious faults such as fatigue cracks, the damaged parts should be replaced in time, and necessary repairs and reinforcements should be carried out.When used in high temperature environments, high temperature resistant lubricants and sealing materials should be selected to improve the durability of the universal joint.
Common faults of double joint universal coupling mainly include abnormal noise, poor maneuverability, steering wheel shaking or body shaking, fatigue cracks and excessive temperature. These problems can be effectively solved through regular inspection and maintenance, correct installation, selection of high-quality products, enhanced lubrication, and treatment of specific faults, ensuring the normal working state of the Double joint universal coupling and the driving safety of the vehicle.
