Problems solved by technology

This scheme adopts the vibration conduction between multiple elastic systems to capture the vibration of the vehicle body. The power to drive the central axis of the generator to rotate mainly comes from the vibration of the sprung vehicle body caused by the excitation of the road surface when the electric vehicle is driving. On the one hand, the flat road will make the sprung vehicle body The amplitude becomes smaller. On the other hand, the bumpy road surface will cause the sprung body to have vibration suppression requirements. Although the traditional shock absorber or damping leaf spring suppresses the vibration of the body through frictional damping, it wastes vibration energy; In actual installation, the setting requirements of the pre-tightening tension spring are relatively high and complicated. Therefore, how to enhance the capture efficiency of the vibration energy of the vehicle body, simplify the method of overcoming the starting torque of the generator, and eliminate the waste of frictional heat energy by the traditional vibration damping device has not yet been updated. perfect solution
