Self-adaption magnetic suspension train damper

The utility model relates to a self-adaption magnetic suspension train damper, which belongs to the technical field of motor vehicle damping. The damper is mainly characterized in that cylindrical permanent magnets and cushion pads are sleeved on a connecting rod at the upper part of a piston of an internal cylinder; a mixture of a liquid and a magnetic material is injected into the internal cylinder; and permanent magnets are sleeved on a groove at the axial middle part of the periphery of the internal cylinder to form the self-adaption magnetic suspension train damper as a replacement of a traditional hydraulic damper. The self-adaption means the instant energy dissipation, which is the premise of good damping effect; and during the energy dissipation, the downward movement of the piston fixed at the end of the connecting rod below the cylindrical permanent magnets is lighter than the upward movement, so as to achieve the effect of suspension for the comprehensive fulfillment of the requirement of the dampi
