Embodiment
[0035] In the embodiment, the outer cylinder 1 and the piston 4 are made of aluminum alloy, and the piston 4 is provided with a second sealing ring 14 to maintain the sealing between the piston 4 and the outer cylinder 1;
[0036] The piston 4 is symmetrically opened with two through holes, which connect the upper liquid chamber 2 and the lower liquid chamber 5. The upper liquid chamber 2 is filled with the magnetorheological fluid 8, and the lower liquid chamber 5 contains the magnetorheological fluid 8, and the liquid level exceeds the lower liquid chamber. connection to the outer catheter.
[0037] The lower end of the piston 4 is connected with the foot pad 6 through the push rod 11, and the three are mechanically connected;
[0038] The upper end of the piston 4 is connected with the lower end of the spring 3 , and the upper end of the spring 3 is fixed on the inner side of the top of the outer cylinder 1 .
[0039] The bottom of the outer cylinder 1 is open, and a cylin...
