Abstract
The utility model discloses an electromagnetic type energy feedback shock absorber based on a Halbach permanent magnet array. Multiple groups of coil windings are distributed in an outer barrel with a groove and led out to be connected with a rectifying circuit by wires, and the outer barrel is made of soft magnetic materials. The Halbach permanent magnet array composed of annular permanent magnet bodies with different polarization directions is installed on an inner barrel. The inner barrel is connected with the outer barrel through a spring. When the shock absorber is installed on a suspension frame of a vehicle in traveling, axial relative displacement is produced between the inner barrel and the outer barrel under a road surface vibration exciting function transferred by axles or wheels, flux linkage of the coil windings in the outer barrel is changed and accordingly induced electromotive force is generated. Due to the fact that the Halbach permanent magnet array has significant single-edge reinforcement characteristic, a magnetic field on the side where magnetic induction strength is intensified is in sinusoidal distribution, higher harmonic is small, and accordingly the shock absorber is small in size and mass and good in energy recovery performance.
