[0002] With the rapid development of the automotive industry, people's demands for vehicle comfort and handling are becoming increasingly stringent. While driving, cars are subject to the impact of various road surface irregularities, such as potholes, bumps, and gravel roads. Shock absorbers, as key components of the vehicle suspension system, have a direct impact on ride comfort. Early automotive shock absorbers were primarily simple friction shock absorbers, which dissipated vibration energy through friction. For example, in older cars, friction between two metal plates was used to mitigate vehicle vibrations. However, this type of shock absorber has limited damping effectiveness and is susceptible to wear and temperature fluctuations. Electric vehicles generally use coil spring shock absorbers, but these are bulky, heavy, and difficult to control in terms of cost. Summary of the Invention
