The life of automobile hydraulic bushing

1. Generally, automobile bushings will not be damaged during use, and there is no problem of how often to replace them. If the differential bushing is broken, it is likely that the gear meshing of the differential is abnormal and should be replaced in time.If there is a problem with the differential bushing, there will be an abnormality when the vehicle turns while driving.

2. It can directly improve the driving texture and driving quality of the car, and instantly find the feeling of youth in the past. In addition, many new cars now use "hydraulic bushings". You can simply understand that these bushings are small "shock absorbers" with oil inside. As long as they do not leak, they will have a much longer life than rubber blocks.

3. The car bushing is generally not damaged during use, and it does not take long to replace it. If the differential bushing is broken, it is likely that the differential has abnormal gear meshing. In this case, it should be replaced in time.

4. Generally, the vehicle should be used for about 2 to 3 years, but it depends on whether the vehicleIf there is a fault, if the vehicle makes abnormal noise or shakes badly, you need to check the rubber cover of the chassis suspension.

5. Rubber products have a certain service life, and it is also normal for rubber products to have aging after long-term use. Therefore, it is normal for the chassis to be inferior to the new car after driving for a period of time.

Which is higher, automobile hydraulic bushing or rubber bushing

1. Both are good. Hydraulic bushings are suitable for the excitation frequency caused by low-frequency action, which has better absorption effect, but the cost is high; while rubber bushings are suitable for occasions where it is inconvenient to install rolling bearings, with the advantages of good lubrication and less maintenance workload, but not applicable to all application scenarios.

2. Two longitudinal hydraulic bushings are used at the junction of the hem arm and the subframe. Compared with ordinary rubber bushings, the cost of hydraulic bushings is relatively higher, and the durability is better than that of rubber bushings.

3. In addition to the suspension itself, Lantu FREE provides a 100mm height adjustable air suspension, which can not only adjust the soft hardness of the suspension, but also adjust the body height and load balance.In addition, we also found that Lantu FREE adopts hydraulic bushing, which suppresses vibration better than rubber bushing, but the cost is higher.

4. Baojun Yunduo is also equipped with a rear suspension hydraulic bushing, and BYD chooses a traditional rubber bushing. Objectively speaking, the cost of hydraulic bushing is higher, which usually appears in some luxury models, which can maximize the vibration isolation function and dynamic performance, reduce the impact energy generated when passing through bumpy road sections, and optimize the handling and comfort of the vehicle.

5. The symmetrical oblique shock absorber on both sides presents an eight-character structure, which can make the vehicle drive more stable, and it also adopts a higher-cost hydraulic bushing. Compared with rubber bushings, the hydraulic bushing has a better absorption effect on the vibration of the suspension.

6. And ordinary rubberCompared with bushing, hydraulic bushing can strengthen the vibration isolation function and dynamic performance of the vehicle to the greatest extent, so that the handling and comfort of the vehicle can be improved synchronously.

How often should the car bushing be replaced

1. Generally, the car bushing will not be damaged during use, and there is no problem of how often to replace it. If the differential bushing is broken, it is likely that the gear meshing of the differential is abnormal and should be replaced in time. If there is a problem with the differential bushing, there will be an abnormality when the vehicle turns while driving.

2. The bushing of the car is generally not damaged during use, and it does not take long to replace it. If the differential bushing is broken, it is likely that the differential has abnormal gear meshing. In this case, it should be replaced in time.

3. About. The rear axle bushing is not expensive, but the manual cost is expensive. It is recommended to replace it with the original factory, which can be used for about 6 years. The rear axle bushing is a part used to connect the rear torsion beam and the car body. When the vehicle turns, the bushing will deform to achieve its correction function and reduce noise, so that the vehicle has good operational stability and ride comfort.
