Abstract

The invention aims to provide an embedded extrusion type magnetorheological shock absorber which comprises a working cylinder, a piston rod, a piston body, magnetorheological fluid, permanent magnet positioning rings, permanent magnet rings I and permanent magnet rings II, wherein the left end face and right end face of the piston body are provided with an annular convex portion respectively. By adopting the embedded extrusion type magnetorheological shock absorber provided by the invention, the existing problems such as relatively small damping force and the like can be solved, simultaneously, the volume of the magnetorheological fluid for work is reduced, and the magnetorheological damping force is greatly improved. The magnetorheological shock absorber has the advantages of less required amount of the magnetorheological fluid and significant magnetorheological effect.

Description

technical field [0001] The invention belongs to the field of magnetorheological technology, and in particular relates to an embedded extrusion magnetorheological shock absorber. Background technique [0002] The magnetorheological shock absorber is a new type of shock absorber that uses the controllable fluid of magnetorheological fluid. Under different magnetic fields, the shear yield strength of the magnetorheological fluid is different, and the shear force that forces the magnetorheological fluid to flow is also different, that is to say, the damping force provided by the magnetorheological shock absorber is variable. Therefore, by controlling the magnetic field generated by the applied current, the purpose of adjusting the damping force of the magneto-rheological shock absorber can be achieved. It is precisely because the magneto-rheological damper has this important engineering application value that it has caused extensive research on the magnetorheological damper in ...
