[0002] In the current booming automobile industry, the comfort and safety of automobiles are increasingly valued, and the damping system, as a key part of ensuring the smooth operation of vehicles and reducing vibration impact, plays an indispensable role. Traditional automobile rubber damping bushings often focus only on the basic damping and buffering functions in design, and mostly use simple rubber and metal inner and outer shell combination structures. Such conventional bushings can still meet the basic damping needs in a stable environment at room temperature, helping to maintain the smoothness of vehicle travel and reducing the interference from road unevenness, vehicle component operation vibration, etc. on the vehicle body and driving experience.

[0003] With the increasing complexity and diversity of automobile use scenarios, traditional rubber damping bushings have exposed many drawbacks in high-temperature and cold weather. The physical properties of rubber materials will change significantly, the Shore hardness will increase significantly, and the elasticity will decrease sharply, resulting in a significant reduction in the buffering and damping effectiveness, which cannot effectively absorb and reduce vibration, seriously affecting the driving comfort of the vehicle, and may also cause additional impact and wear on other related components of the vehicle due to poor damping. At the same time, when maintenance personnel need to replace and maintain the core components such as rubber bushings inside the bushing, the operation is extremely inconvenient, often requiring a lot of time and effort to disassemble, and even the shell structure may be damaged due to forced disassembly, further affecting the vehicle repair efficiency and economy.

[0004] Therefore, it is necessary to provide a new automobile rubber damping bushing to solve the above technical problems. INVENTION CONTENTS
