detailed description

During operation, the upper suspension ring 1 is connected with the pin shaft of the automobile body, and the lower suspension ring 3 is connected with the pin shaft of the wheel shaft. During the driving process of the automobile, due to the impact, there is vibration, so that the housing 5 fixedly connected with the lower suspension ring 3 and the upper suspension ring 1 There is relative movement up and down in the fixedly connected rack 7 .

The up and down relative movement of the rack 7 relative to the housing 5 is converted into the rotational movement of the motor rotor 12 relative to the motor stator 11 through the gear 8, the shaft 6, the large hypoid gear 9 and the small hypoid gear 10, thereby generating electricity.

When the motor rotor 12 rotates relative to the motor stator 11, it will be affected by the magnetic resistance torque. This resistance plus the impact resistance generated by the gear meshing process makes the upper suspension ring 1 and the lower suspension ring 3 have a resistance effect when they move, achieving a vibration reduction effect.
