Dual core magneto-rheological damper

Abstract

The application discloses a double-core magneto-rheological damper, which comprises an outer cylinder and a piston, the outer cylinder is filled with magneto-rheological fluid, and the piston divides the inner cavity of the outer cylinder into a recovery cavity and a compression cavity; a magnetic field generator is arranged on the piston, the magnetic field generator comprises a compression magnetic field generator which is electrified in the compression stroke of the piston and a recovery magnetic field generator which is electrified in the recovery stroke of the piston, the magnetic field strength generated by the compression magnetic field generator is different from that generated by the recovery magnetic field generator, the compression magnetic field generator and the recovery magnetic field generator are arranged on the piston, an integrated iron core is adopted, the winding is separately wired, and a one-way valve is arranged on both sides of the piston, so that the size and the adjusting range of the damping force output can be improved, the energy consumption economy can be optimized, the damage to the magnetic field of the piston can be reduced, the risk of magneto-rheological fluid leakage can be reduced, the standardization and the rapid sample production can be realized, and the processing difficulty and the manufacturing cost can be reduced.
