A magnetorheological fluid shock absorb

The invention discloses a magnetorheological fluid shock absorber, comprising a magnetorheological fluid shock absorber and a self-generating system. A magnetorheological fluid shock absorb comprisesa piston rod, a piston body assembly, a cylinder barrel, a damping hole and a magnetorheological fluid; Self-generating systems include generators, sector gears, and solenoids. The rack is fixed on the piston rod through bolts, and the sector gear meshes with the rack, and the sector gear is connected with the generator through a sleeve coupling, leads out wires at both ends of the generator, andconnects the electromagnetic coil to form a closed loop. The solenoid is evenly wound around the cylinder. When the automobile is running on the uneven road, the rack on the piston rod makes reciprocating linear motion to drive the sector gear to rotate, and the sector gear to drive the generator to rotate, thus producing a certain electric current. The magnitude of current affects the viscosity of MR fluid, and then chang
