Description

1. Technical field [0001] The invention relates to automobile suspension system components, in particular to an energy feedback type automobile active suspension electromagnetic damping device with adjustable damping. 2. Background technology [0002] The shock absorber is an important part of the automobile suspension system. Its main function is to absorb the vibration generated by the uneven road surface, alleviate the impact brought by the road surface, and meet the requirements of ride comfort and handling stability during the operation of the automobile. At present, the cylinder type hydraulic shock absorber commonly used in automobiles uses the friction between the oil and the piston hole when the piston moves in the piston cylinder and the internal friction between the oil molecules to form a damping force, so that the vibration energy of the automobile is converted into oil. The thermal energy of the liquid is then dissipated into the atmosphere by the shock absorbe...
