The utility model discloses a magneto rheological damper with two -stage damping force output control mainly comprises piston rod, attenuator end cover, attenuator cylinder body, piston head, piston head end cover, piston sleeve, an excitation coil, the 2nd excitation coil and spring etc.. When switching on for an excitation coil and the 2nd excitation coil respectively, flow channel leads to entirely, seals to hold chamber I and seal the pressure differential that holds chamber II little, and the output damping force is also little, and this is first kind of operating condition of attenuator. When excitation coil circular telegram, when the 2nd excitation coil cut off the power supply, the flow channel part was stopped up, sealed and held chamber I and the closed pressure differential increase of holding chamber II, and the output damping force also increases thereupon, and this is the second kind operating condition of attenuator. The utility model discloses under the prerequisite that does not increase ove
