Jiabao v52 seems to be falling apart when driving at 70 kilometers per hour. What is the reason?

The chassis is loose, the rubber sleeve of the balance bar is aging, and the rubber connecting the connecting rod and the car body is aging.

1, the chassis is loose, and the suspension system includes connecting rod, spring, damping and balance bar. When the wheel is in contact with the ground, it will vibrate when passing through the uneven road surface, and the suspension will move up and down to absorb the vibration from the ground. Driving on the uneven road for a long time will cause some damage to the suspension and produce the feeling of loose chassis.

2. The rubber sleeve of the balance bar is aging. The suspended balance bar is designed to prevent the vehicle from tilting seriously and keep the vehicle balanced, and it is also designed for better handling. The force on the balance bar is also a fulcrum. If the rubber sleeve on it ages, it will produce squeaky and twisted abnormal sound.

3. The rubber of connecting rod and connecting body is aging. The looseness or abnormal sound of most chassis is almost caused by the aging of the connecting rod and the rubber connecting the car body. When the suspension bumps for a long time, the connecting rod is connected with the car body, which will release heat, just like the joints of the human body. After a long time, it will definitely age.
