英文How to determine if the vibration isolator needs to be replaced?
2025-12-04
To determine whether the vibration isolator needs to be replaced, the following aspects can be considered:
1. Mileage and time traveled:
- In general, the service life of vibration isolators is about 50000 to 80000 kilometers or 3-5 years. If the vehicle's mileage or time is close to this range, it is recommended to check and consider replacing the vibration isolators in a timely manner.
2. Appearance inspection of vibration isolators:
- Check if there is any oil leakage in the vibration isolator. If there are oil stains or droplets on the cylinder wall and lower lifting ring of the vibration isolator, it may indicate that there is an oil leakage problem with the vibration isolator.
- Observe whether the appearance of the vibration isolator is damaged or deformed, which may be a sign of internal damage to the vibration isolator.
3. Riding experience:
- When the vehicle passes over bumps or potholes at a moderate speed, pay attention to the bouncing and vibration of the body. If the vibration isolator fails, the vehicle body will produce a large amplitude of vibration, and the vibration may last for a long time.
4. Monomer test:
- Remove the vibration isolator from the car for individual testing, and check whether its resistance is stable by pulling and pressing the vibration isolator rod. If the resistance is unstable or there is no resistance, it may indicate that there is an internal problem with the vibration isolator.
5. Temperature inspection:
- After driving a certain distance on a road with poor road conditions, touch the vibration isolator housing. If it doesn't feel hot enough, it may indicate that there is no resistance inside the vibration isolator, that is, the vibration isolator is not working.
In summary, if the vibration isolator experiences oil leakage, damage and deformation, significant deterioration in riding sensation, abnormal individual testing or temperature inspection, etc., replacement of the vibration isolator should be considered. Timely replacement of vibration isolators can ensure the safety and comfort of driving. At the same time, it is recommended to regularly inspect and maintain vibration isolators to extend their service life.
