Abstract
The invention discloses a single-rod multistage diffraction passive double-control variable-damping magnetorheological damper and belongs to the field of variable-damping magnetorheological fluid instruments. The magnetorheological damper comprises a rheological fluid cylinder body, a left end cover module, a right end cover module, a diffraction piston module arranged in the rheological fluid cylinder body, a large working clearance opening and a small working clearance opening. The diffraction piston module comprises a diffraction piston body, a piston rod, left piston magnets, right piston magnets, left piston protective layers and right piston protective layers. A diffraction orifice bent in an S shape is formed in the diffraction piston body, and the internal diameter of the diffraction orifice gradually changes. The internal diameter of a hole in one end of the diffraction orifice is large and serves as the large working clearance opening, and the internal diameter of a hole in the other end of the diffraction orifice is small and serves as the small working clearance opening. When the diffraction piston module moves, the diffraction orifice is changed into a working clearance for magnetorheological fluid to flow. The magnetorheological damper is simple and reasonable in structure and wide in damping force adjusting range, and the variable working clearance and a permanent magnetic field are arranged.

In order to solve the problem, the solution that the present invention proposes is: the multistage diffraction of single pole passive dual control mutative damp MR damper, it comprise stream become liquid cylinder, be installed in described stream become liquid cylinder left end left end cap module, be installed in described stream become liquid cylinder right-hand member right end cap module, be installed in described stream and become the diffraction piston modules of liquid cylinder inside, working clearance large mouth and working clearance osculum.
It is hollow cylinder that stream of the present invention becomes liquid cylinder, and its internal diameter equals the maximum diameter of described diffraction piston modules; Described left end cap module comprises left end cap, is installed in the left end cap magnet inside described left end cap, the left end cap protective layer be installed on described left end cap magnet; Described right end cap module comprises right end cap, is located at the bearing hole of described right end cap center, the linear bearing be installed in described bearing hole, be installed in the right end cap magnet inside described right end cap, the right end cap protective layer be installed on described right end cap magnet; Described diffraction piston modules comprises diffraction piston only, piston rod, the left magnet of piston, the right magnet of piston, the left protective layer of piston, the right protective layer of piston.
Diffraction piston only of the present invention offers the diffraction throttle orifice of one serpentine bend internal diameter gradual change; One end perforate internal diameter of described diffraction throttle orifice is comparatively large, and be large mouth of described working clearance, the other end perforate internal diameter is less, is described working clearance osculum; One end of described piston rod is equiped with described diffraction piston only, and the other end, by described right end cap protective layer, described right end cap magnet and described linear bearing, reaches the outside that described stream becomes liquid cylinder; The inner space that described stream becomes liquid cylinder is divided into stream and becomes the left room of liquid and Liu Bian liquid right ventricle by described diffraction piston modules; It is identical with large mouth of described working clearance that described stream becomes the left room of liquid, and described Liu Bian liquid right ventricle is identical with described working clearance osculum; During described diffraction piston modules motion, diffraction throttle orifice becomes the working clearance of magnetic flow liquid flowing.
Compared with prior art, the invention has the advantages that: the multistage diffraction of single pole of the present invention passive dual control mutative damp MR damper is provided with diffraction piston only, diffraction piston only offers the diffraction throttle orifice of serpentine bend, when by the working clearance, large mouth flows into magnetic flow liquid, because the internal diameter of diffraction throttle orifice is more and more less, damping force diminishes, otherwise when being flowed into by working clearance osculum, damping force increases; The present invention is also provided with end cap magnet and piston magnet, effectively prevent the sedimentation of suspended particulate.It can thus be appreciated that the present invention is simple and reasonable, adopt and become the working clearance and widened damping force regulation range, and improve the stability of magnetic flow liquid.
