Abstract

The invention discloses a single outstretch pole magneto-rheological damper with an annular piston. A working cylinder of the single outstretch pole magneto-rheological damper with the annular piston has an inner-layer structure and an outer-layer structure; the annular piston is installed in an annular cavity between an inner layer and an outer layer of the working cylinder; and the annular piston is used for compensating volume change in the working cylinder caused when a piston rod enters and departs from the working cylinder so as to increase the working stroke of the magneto-rheological damper.

Description

technical field [0001] The invention relates to a magnetorheological damper, in particular to a single-rod magnetorheological damper with an annular piston. Background technique [0002] The current piston magneto-rheological damper is mainly divided into single-rod magnetorheological damper and double-rod magnetorheological damper; the double-rod magnetorheological damper is symmetrically installed at both ends of the piston with two identical diameter of the piston rod, when the piston moves in the cylinder, one piston rod enters the working cylinder while the other piston rod exits the working cylinder, so the volume in the working cylinder remains unchanged; Because the damper is only equipped with a piston rod at one end of the piston, when the piston moves in the cylinder, the volume in the working cylinder will change due to the piston rod entering and leaving the working cylinder. In order to work normally, it is necessary to compensate the change in the internal vo...
